Forecasting purchasing power of one currency with respect to another currency is always an interesting topic in the field of financial time series prediction. Despite the existence of several traditional and computational models for currency exchange rate forecasting, there is always a need for developing simpler and more efficient model, which will produce better prediction capability. In this paper, an evolutionary framework is proposed by using an improved shuffled frog leaping (ISFL) algorithm with a computationally efficient functional link artificial neural network (CEFLANN) for prediction of currency exchange rate. The model is validated by observing the monthly prediction measures obtained for three currency exchange data sets such as USD/CAD, USD/CHF, and USD/JPY accumulated within same period of time. The model performance is also compared with two other evolutionary learning techniques such as Shuffled frog leaping algorithm and Particle Swarm optimization algorithm. Practical analysis of results suggest that, the proposed model developed using the ISFL algorithm with CEFLANN network is a promising predictor model for currency exchange rate prediction compared to other models included in the study.

Soft currencies, cash economies, new monies: past and present.

Guyer, Jane I

2012-02-14

Current variation in the forms of money challenges economic anthropologists and historians to review theory and comparative findings on multiple currency systems. There are four main sections to the paper devoted to (i) the present continuum of hard to soft currencies as an instance of multiplicity, including discussion of different combinations of the classic four functions of money, especially the relationship between store of value and medium of exchange; (ii) the logic of anthropological inquiry into multiple currency economies; (iii) the case of the monies of Atlantic Africa, applying the analytics of exchange rates as conversions to African transactions; and (iv) the return to economic life in a present day Nigerian economy lived in soft currency and cash. The paper identifies five findings that suggest foci for future research. (i) The widespread occurrence of conversions, which bring together ranking principles within transactions. (ii) Several types of positional ranking ranging from simple stepwise ordinal scales to iconic ordinality that creates a parabolic curve of value. (iii) Fictional units of account that serve to mediate both the memorization of nonreductive transactions and their nature as conversions. (iv) The importance of the temporal reach of what constitutes wealth: over the short run, the life span, intergenerational succession, and in (legal) perpetuity (as for corporate and sovereign debts and specified assets). (v) The social niches in which these qualities are brought together in transactional regimes. In conclusion, the paper returns to the exchange function of cash, soft currencies, and new money forms.

NATIONAL CURRENCY INSTABILITY

The concept related to currency stability includes internal currency stability as intern price stability, the money demand and supply stability and the stability of the interest rate. Also it includes external currency stability through exchange rate mechanism. The equilibrium of national economy is determined by the evolution of inflation and by the evolution of nominal exchange rate mechanism as an expression of external stability.

Chaoticity in the time evolution of foreign currency exchange rates in Turkey

Cakar, O.; Aybar, O. O.; Hacinliyan, A. S.; Kusbeyzi, I.

Tools from chaos theory that have found recent use in analysing financial markets have been applied to the US Dollar and Euro buying and selling rates against the Turkish currency. The reason for choosing the foreign exchange rate in this analysis is the fact that foreign currency is an indicator of not only the globalization of economy but also savings and investment. In order to test the globality assumption and to ascertain the degree of involvement of local conditions in Turkey, the Euro and US dollar exchange rates have been subjected to the same analysis.

The impact of currency clause and exchange rate on Serbian economy

2012-01-01

Full Text Available In nineties Serbia survived the disintegration of the former Yugoslavia, intense UN sanctions, and 1999 78 days of bombing by NATO. This has resulted in a drop in production and hyperinflation. The confidence in the national currency the dinar has been lost. In order to do business in Serbia returned to normal framework the Law on Foreign Exchange imposed the possibility of nomination the loans in foreign currencies. This prompted the business, but it meant a de facto legalization of dual currency system. The logical consequence was the high degree of dollarization. It is important to mention that the dual currency system limited the possibilities of monetary policy of the National Bank of Serbia. Dollarization after the first positive results showed their expected bad sides. Appreciation of the dinar was one of the consequences. The trade deficit and foreign debt grew. Due to the appreciation production rate remained at 40% of its 1989 level, and unemployment has risen to 27%. The benefit of the appreciation had only importers and foreign-owned banks. They take out the capital abroad. Therefore, it is necessary to make changes to the Foreign Exchange Law and abolish foreign currency clause at least for a new loans.

Currency Boards; The Ultimate Fix?

Atish R. Ghosh

1998-01-01

The growing integration of world capital markets has made it fashionable to argue that only extreme exchange rate regimes are sustainable. Short of adopting a common currency, currency board arrangements represent the most extreme form of exchange rate peg. This paper compares the macroeconomic performance of countries with currency boards to those with other forms of pegged exchange rate regime. Currency boards are indeed associated with better inflation performance, even allowing for potent...

In Search for a Measure of Currency Misalignment: the Case of the 1997 Asian Currency Crisis

Directory of Open Access Journals (Sweden)

Daekeun Park

2000-03-01

Full Text Available The paper searches for an appropriate measure of currency misalignment in light of the 1997 Asian currency crisis. A couple of measures of currency misalignment, one based on purchasing power parity and the other based on equilibrium real exchange rate that is consistent with internal and external equilibrium are used to estimate the degree of currency misalignment for Korea, Indonesia, Malaysia, and Thailand before the 1997 currency crisis. The paper finds that the purchasing power parity based methods show that the Asian currencies were not significantly overvalued on the eve of the crisis. On the other hand, measures based on the equilibrium real exchange rate concept demonstrate that the Asian currencies were significantly overvalued. In consequence, the equilibrium real exchange rate based method seems to be a useful candidate for a measure of currency misalignment.

THE CHOICE OF THE EXCHANGE RATE REGIMES OF THE EUROPEAN UNION ACCESSION COUNTRIES INFLUENCED BY THE WORLD CURRENCY CONSOLIDATION

Directory of Open Access Journals (Sweden)

Marin Frâncu

2004-05-01

Full Text Available The pressure of the currency consolidation increased in the years 1990 as the world currency system became obviously too complicated and too costly. There are too many national currencies that generate artificial barriers and avoidable transaction costs, both for the domestic economies and for the world economy. The high costs and great vulnerability of the national currencies determined the financial and economic business of small open economies to move into the major currencies of the world. The world needs fewer national currencies, but does it need fewer central banks too? Or it needs central banks capable to pursuit sound monetary policies? What kind of institutional arrangements and international financial architecture are most suitable for the prospective environment of a greatly reduced multiplicity of currencies? A regional currency consolidation may be a good answer but a regional currency union is a better answer. Though, until membership of the Euro zone, what kind of the exchange rate regime is more suitable for Romania and other European Union accession countries? The hard peg regimes seem not to be a good solution. The best solution lays probable between managed floating regimes and intermediate regimes. This may be because emerging markets have both “fear of floating” and “fear of fixing”. But there is no ideal exchange rate regime”to suit everybody”. Once the exchange rate regime chosen, it evolves in time. So is the case with the exchange rate benchmarks for the national currency.

Some stylised facts about the exchange rate behaviour of Central European currencies

Directory of Open Access Journals (Sweden)

Jan Vejmělek

2016-04-01

Full Text Available The paper investigates developments of exchange rate time series of Central European currencies and tries to find evidence of some stylised facts. Statistical methods and an econometric approach to the univariate time series modelling of high-frequency data, i.e., daily, are used. The main conclusions are as follows: (1 All the CE nominal exchange time series are not stationary: nevertheless, stationarity of all the return time series was confirmed. (2 Volatility clustering was proven and the GARCH modelling approach was successfully applied, including asymmetric modelling of volatility. (3 The more flexible an exchange rate regime is, the more volatile the respective currency. This is true for both nominal and real exchange rates. While nominal volatility is lower than real volatility in a system of fixed or less flexible exchange rates, the opposite is true for flexible systems: exchange rate volatility is higher in nominal terms than in real terms.

The Pricing of Foreign Currency Futures Options

OpenAIRE

Chang Mo Ahn

We derive semi-closed form solutions for the forward and futures exchange rates, European foreign currency options, currency forward options, and currency futures options when the domestic and foreign interest rate movements follow mean reverting diffusion processes. These solutions are consistent with the Black-Scholes option formula so that they can be easily applied. The impact of interest rate uncertainty on theoretical prices of currency futures options is too significant to be neglected.

What currency do bumble bees maximize?

Directory of Open Access Journals (Sweden)

Nicholas L Charlton

2010-08-01

Full Text Available In modelling bumble bee foraging, net rate of energetic intake has been suggested as the appropriate currency. The foraging behaviour of honey bees is better predicted by using efficiency, the ratio of energetic gain to expenditure, as the currency. We re-analyse several studies of bumble bee foraging and show that efficiency is as good a currency as net rate in terms of predicting behaviour. We suggest that future studies of the foraging of bumble bees should be designed to distinguish between net rate and efficiency maximizing behaviour in an attempt to discover which is the more appropriate currency.

Bitcoin as a decentralized currency

Directory of Open Access Journals (Sweden)

Dinić Vladimir

2014-01-01

Full Text Available Bitcoin is the first decentralized peer-to-peer crypto-currency founded in 2009. Its main specificity is the fact that there is no issuer of this currency. On the other hand, the supply of this currency is software-programmed and limited. Among other things, its main features are relatively secure payments, low transaction costs, anonymity, inability of counterfeiting, irreversibility of transactions, but also extremely unstable exchange rate. Despite many advantages, the use of this currency is subject of numerous discussions, as this currency offers the possibility of performing various abuses and criminal activities. The future of this and other currencies in this regard depends on both security and privacy of these currencies, and legal regulation of such payments.

Currency Crisis Revisited: A Literature Review

Directory of Open Access Journals (Sweden)

Teuta Ismaili Muharremi

2015-12-01

Full Text Available This paper elaborates on currency crisis, focusing on the main factors causing the currency crisis. After a brief overview of the main factors driving currency crisis, the paper provides a literature review highlighting that the history of the global economy experienced a number of currency crisis whereas as relates to the triggers of the currency crisis there are three generations of models that have been used to explain currency crisis during the last four decades. Underscoring the role of the government in financial market, in particular the evolution of this role as a result of the recent global financial crisis and highlighting other factors that trigger such crisis, the paper concludes that the potential financial crisis can be addressed using early warning system, which consists of indicators proven to be beneficial in anticipation of the currency crisis, and using the advanced empirical models of currency crisis. In this context the paper reveals that currency crisis are associated with all factors impacting them such as inflation, real exchange rate, import growth, US interest rates, public debt/GDP, and current account/GDP – all with a slightly different time lag.

Unemployment Gap in the Currency Board Regime

A currency board combines three elements: a fixed exchange rate between a country’s currency and an “anchor currency,” automatic convertibility, and a long-term commitment to the system, often made explicit in the central bank law. The main reason for countries to consider a currency board is to demonstrate that they are pursuing an anti-inflationary policy. The mechanism works through changes in the money supply, which lead to interest rate changes, which, in turn, encourage funds to move be...

Currency speculation and dollar fluctuations

Directory of Open Access Journals (Sweden)

Stephan Schulmeister

1988-12-01

Full Text Available In this study the reasons behind the wide fluctuations of the dollar exchange rate following the breakdown of the Bretton Woods system, for the most part unexplained by the prevailing exchange rate theories, are explored. To do so, the author investigates the exchange rate between the two most traded currencies, the dollar and the deutschemark, from 1973 to 1988. In the first part, the pattern of the daily exchange rate movements is examined to show that a sequence of upward and downward trends interrupted by non-directional movements is typical of exchange rate dynamics in the short run. Moreover, this pattern is systemically exploited through currency speculation, particularly through the use of “technical analysis”. In the second part, the author focuses on the medium-term, arguing that fluctuations can be explained as the result of interacting disequilibria in the goods and asset markets. Although currency speculation has been systemically profitable for most currencies, it should be considered to be destabilizing since the sequence of price runs caused large and persistent deviations of exchange rates from their equilibrium values (purchasing power parity.

Country Fundamentals and Currency Excess Returns

Directory of Open Access Journals (Sweden)

Daehwan Kim

2014-06-01

Full Text Available We examine whether country fundamentals help explain the cross-section of currency excess returns. For this purpose, we consider fundamental variables such as default risk, foreign exchange rate regime, capital control as well as interest rate in the multi-factor model framework. Our empirical results show that fundamental factors explain a large part of the cross-section of currency excess returns. The zero-intercept restriction of the factor model is not rejected for most currencies. They also reveal that our factor model with country fundamentals performs better than a factor model with usual investment-style factors. Our main empirical results are based on 2001-2010 balanced panel data of 19 major currencies. This paper may fill the gap between country fundamentals and practitioners' strategies on currency investment.

This paper proposes a model for discrete-time hedging based on continuous-time movements in portfolio and foreign currency exchange rate returns. In particular, the vector of optimal currency exposures is shown to be given by the negative realized regression coefficients from a one......-period conditional expectation of the intra-period quadratic covariation matrix for portfolio and foreign exchange rate returns. These are labelled the realized currency betas. The model, hence, facilitates dynamic hedging strategies that depend exclusively on the dynamic evolution of the ex-post quadratic...... covariation matrix. These hedging strategies are suggested implemented using modern, yet simple, non-parametric techniques to accurately measure and dynamically model historical quadratic covariation matrices.

Full Text Available The high volatility combined with unpredictable fluctuations of CZK had shown one more time to the Czech exporting companies the necessity of currency hedging. This article is focused on finding of suitable currency hedging instrument for exporting company, working with the currency pair of CZK/EUR. In the first part, the time series analysis is made for volatility, interest rates and exchange rate. Based on the real market data – gained from Thomson REUTERS and CNB for the time period starting in 2002 – the detailed analysis is made in graphical form. The main goal is to find out the future trends with help of liner regression analysis, based on the historical data. Several graphs are provided with the trend line end estimated interval (min and max for the each variable. The calculated values are clearly marked, to be separated from the real market data. Exchange rate curve shows the market behaviour in the last years and is to be used as most important indicator for the future trends. Interest rates curves are very important for the calculation of the BIPS (basis points, determining the price of the forwards. The difference between landing and deposit rates for the same period of time and different currencies are showing the market estimation of the future development of each currency. Forward price is to be seen as a benchmark for the all other financial instruments. And finally the volatility (quoted as middle is very important part in the pricing of currency options.The second part is closely connected with the first one. Based on the results of provided analyses, it recommends a suitable hedging product for the next period of time. All of the analyses are taken as an input in different ways. The volatility is important for the decision of selling or purchasing the specific part of currency option. The exchange rate outlook together with the interest rates is the indicator of the future development of the currency pair and is playing

2017-11-01

The advancement of color printing technology has increased the rate of fake currency note printing and duplicating the notes on a very large scale. Few years back, the printing could be done in a print house, but now anyone can print a currency note with maximum accuracy using a simple laser printer. As a result the issue of fake notes instead of the genuine ones has been increased very largely. India has been unfortunately cursed with the problems like corruption and black money. And counterfeit of currency notes is also a big problem to it. This leads to design of a system that detects the fake currency note in a less time and in a more efficient manner. The proposed system gives an approach to verify the Indian currency notes. Verification of currency note is done by the concepts of image processing. This article describes extraction of various features of Indian currency notes. MATLAB software is used to extract the features of the note. The proposed system has got advantages like simplicity and high performance speed. The result will predict whether the currency note is fake or not.

Currency Policy Coordination оf Asean Countries: Foreign Trade Effects

Directory of Open Access Journals (Sweden)

Yana Valeryevna Dyomina

2015-12-01

Full Text Available The study estimates foreign trade effects of currency policy measures in ASEAN countries. On the base of exchange rate dynamics the author concludes that during the period of 2000-2014 ASEAN countries in general used competitive devaluation policy of national currencies to CNY, JPY, KRW and EUR and revaluation to USD. To eliminate negative effects of competitive devaluation policy the paper proposes currency policy coordination of ASEAN countries that could be done by pegging of national currencies to a common basket. Employing the SAC (Stable Aggregate Currency method the author suggests 4 options for a common currency basket. The researcher estimates foreign trade effects of currency policy coordination in ASEAN countries for every option of a currency basket in three following cases: ASEAN as a whole, ASEAN-6 and ASEAN-4. The author concludes that the optimal form of currency policy coordination in ASEAN is pegging of exchange rates of national currencies to a common basket composed of 13 East Asian currencies. This currency basket option has maximum foreign trade effects for the Association as a whole and by sub-groups of ASEAN-6 and ASEAN-4 when it devaluates to the U.S. dollar

Sovereign Risk and Currency Returns

DEFF Research Database (Denmark)

Della Corte, Pasquale; Sarno, Lucio; Schmeling, Maik

We empirically investigate the relation between sovereign risk and exchange rates for a broad set of currencies. An increase in the credit default swap (CDS) spread of a country is accompanied by a significant depreciation of the exchange rate. More generally, CDS spread changes have substantial...... explanatory power for currency returns which is largely driven by shocks to global credit risk. Consistent with the notion that sovereign risk is priced, we find that a country's exposure to global credit risk forecasts excess returns to trading exchange rates as well as to trading on the volatility, skewness...

A comparative examination of currency risk pricing and market integration in the stock markets of Nigeria and South Africa

Directory of Open Access Journals (Sweden)

Odongo Kodongo

2012-07-01

Full Text Available We examine the pricing of currency risk and market integration in the equity markets of Nigeria and South Africa. Using the Generalized Method of Moments with a multi-beta asset pricing model and firm-level data, we find that currency risk is partly unconditionally priced in South Africa's stock market, with this market being largely integrated with the world equity markets. Conversely, currency risk is not priced in Nigeria's equity market, which also shows no evidence of integration with the world equity markets. Interestingly, a portfolio analysis of firms reveals a size based return sensitivity to both world equity markets and exchange rate volatility across the two countries. Therefore, while general results suggest that Nigeria, rather than South Africa, would provide greater diversification benefits to international investors with little or no worry about hedging unconditional exchange rate risk, that view must be nuanced when considering large size firms which are consistently sensitive to the two factors across both countries.

Full Text Available We modeled the currency networks through the use of REER (real effective exchange rate instead of a bilateral exchange rate in order to overcome the confusion in selecting base currencies. Based on the MST (minimum spanning tree approach and the rolling-window method, we constructed time-varying and correlation-based networks with which we investigate the linkage effects among different currencies. In particular, and as the source of empirical data, we chose the monthly REER data for a set of 61 major currencies during the period from 1994 to 2014. The study demonstrated that obvious linkage effects existed among currency networks and the euro (EUR was confirmed as the predominant world currency. Additionally, we used the rolling-window method to investigate the stability of linkage effects, doing so by calculating the mean correlations and mean distances as well as the normalized tree length and degrees of those currencies. The results showed that financial crises during the study period had a great effect on the currency network’s topology structure and led to more clustered currency networks. Our results suggested that it is more appropriate to estimate the linkage effects among currency networks through the use of REER data.

Dollar as the world's reserve currency: Challenges and prospects

Directory of Open Access Journals (Sweden)

Kovačević Radovan

2014-01-01

Full Text Available The US dollar gained the status of the world's reserve currency in the Bretton Woods system and has preserved it until the present day. Such position in international finance entails both advantages and disadvantages to the USA as the issuer of this currency, and to the rest of the world using it in trading, as store of value, and for the purpose of various financial operations and transactions. After the collapse of the Bretton Woods system, the regime of fixed FX rates was replaced by floating FX rates. Yet, regardless of this change, the dollar kept its role of the world's reserve currency. Numerous banking and currency crises following the transfer to the floating FX rates regime, along with the shifts in international capital flows, forced the developing countries and countries in transition to increase their FX reserves. In the tendency to store their value, central banks usually invest them into US Treasury securities, as liquid and reliable assets. However, due to the risk incurred by the reliance on a single national currency in the role of the world's reserve currency, there have been many proposals to reform the international monetary system. According to the current global tendencies, the most serious candidates for acquiring the status of the world's reserve currency in the future are the dollar, the euro, and the Chinese yuan.

Currency Substitution and Inflation in Peru

We draw on a new data set on the use of Swiss francs and other currencies by European banks to assess the patterns of foreign currency bank lending. We show that the patterns differ sharply across foreign currencies. The Swiss franc is used predominantly for lending to residents, especially households. It is sensitive to the interest rate differential, exchange rate developments, funding availability, and to some extent international trade. Lending in other currencies is more used in lending ...

Evolutionary Topology of a Currency Network in Asia

Science.gov (United States)

Feng, Xiaobing; Wang, Xiaofan

Although recently there are extensive research on currency network using minimum spanning trees approach, the knowledge about the actual evolution of a currency web in Asia is still limited. In the paper, we study the structural evolution of an Asian network using daily exchange rate data. It was found that the correlation between Asian currencies and US Dollar, the previous regional key currency has become weaker and the intra-Asia interactions have increased. This becomes more salient after the exchange rate reform of China. Different from the previous studies, we further reveal that it is the trade volume, national wealth gap and countries growth cycle that has contributed to the evolutionary topology of the minimum spanning tree. These findings provide a valuable platform for theoretical modeling and further analysis.

OPPORTUNITIES FOR DECREASING EXCHANGE RISKS OF FOREIGN CURRENCY TRANSACTIONS IN ENTERPRISES WITH A SPECIAL REGARD ON CHANGING-OVER FOREIGN CURRENCY BOOKING

Directory of Open Access Journals (Sweden)

ROZSA ATTILA

2014-07-01

Full Text Available The profitability of the operation of an enterprise is influenced by several factors. Besides the tendency of market demand and supply, taking the changes of inflation, interest rate and exchange rate into consideration is necessary, as all these are risks. Since the start of the economic crisis in the autumn of 2008, changes in the exchange rate have been more and more emphasized. The article deals with methods for decreasing exchange risks of foreign currency transactions, without the need of completeness. In international trade due to the growth of the number of currency loans the significance of managing financial risks coming from the changes in exchange rates has increased. One of its tools is the currency based booking, which may make the effect of the change more predictable.

A PDE Pricing Framework for Cross-Currency Interest Rate Derivatives with Target Redemption Features

Science.gov (United States)

Christara, Christina C.; Minh Dang, Duy; Jackson, Kenneth R.; Lakhany, Asif

2010-09-01

We propose a general framework for efficient pricing via a partial differential equation (PDE) approach for exotic cross-currency interest rate (IR) derivatives, with strong emphasis on long-dated foreign exchange (FX) IR hybrids, namely Power Reverse Dual Currency (PRDC) swaps with a FX Target Redemption (FX-TARN) provision. The FX-TARN provision provides a cap on the FX-linked PRDC coupon amounts, and once the accumulated coupon amount reaches this cap, the underlying PRDC swap terminates. Our PDE pricing framework is based on an auxiliary state variable to keep track of the total accumulated PRDC coupon amount. Finite differences on uniform grids and the Alternating Direction Implicit (ADI) method are used for the spatial and time discretizations, respectively, of the model-dependent PDE corresponding to each discretized value of the auxiliary variable. Numerical examples illustrating the convergence properties of the numerical methods are provided.

Alternative international currencies

Directory of Open Access Journals (Sweden)

Rozhentsova Vladimirovna Elena

2012-01-01

Full Text Available The modern international monetary system has a number of flaws and therefore needs cardinal change. Hence, economists from all over the world are suggesting alternative international currencies that would make the international monetary system more efficient. However, it is essential when approaching the creation of a new international currency to analyze and take into account the experience of all the past international currencies. Therefore this paper begins with an exploration of the drawbacks of each of the past and present international currencies. Drawing on this analysis a justification will be made for the necessity of introducing a new international currency, pointing to the requirements it should meet. Further on, this paper proposes an alternative theoretically possible variant of the international currency, with a fixed value relative to a commodity basket. An abstract example is used to demonstrate its composition and circulation mechanism.

Forecasting of magnitude and duration of currency crises based on the analysis of distortions of fractal scaling in exchange rate fluctuations

Science.gov (United States)

Uritskaya, Olga Y.

2005-05-01

Results of fractal stability analysis of daily exchange rate fluctuations of more than 30 floating currencies for a 10-year period are presented. It is shown for the first time that small- and large-scale dynamical instabilities of national monetary systems correlate with deviations of the detrended fluctuation analysis (DFA) exponent from the value 1.5 predicted by the efficient market hypothesis. The observed dependence is used for classification of long-term stability of floating exchange rates as well as for revealing various forms of distortion of stable currency dynamics prior to large-scale crises. A normal range of DFA exponents consistent with crisis-free long-term exchange rate fluctuations is determined, and several typical scenarios of unstable currency dynamics with DFA exponents fluctuating beyond the normal range are identified. It is shown that monetary crashes are usually preceded by prolonged periods of abnormal (decreased or increased) DFA exponent, with the after-crash exponent tending to the value 1.5 indicating a more reliable exchange rate dynamics. Statistically significant regression relations (R=0.99, pcurrency crises and the degree of distortion of monofractal patterns of exchange rate dynamics are found. It is demonstrated that the parameters of these relations characterizing small- and large-scale crises are nearly equal, which implies a common instability mechanism underlying these events. The obtained dependences have been used as a basic ingredient of a forecasting technique which provided correct in-sample predictions of monetary crisis magnitude and duration over various time scales. The developed technique can be recommended for real-time monitoring of dynamical stability of floating exchange rate systems and creating advanced early-warning-system models for currency crisis prevention.

The Official Use of International Currencies – Assessments and Implications

Directory of Open Access Journals (Sweden)

Orăștean Ramona

2015-12-01

Full Text Available The paper analyses the official use of international currencies as reserve currency (store of value and anchor currency (unit of account. Examining the role as a reserve currency we note that the US dollar is the main reserve currency even if it recorded a decline given the decrease of the value of the US dollar reserve holdings and the gradual diversification of the currencies used. Since 2010, the euro's share decreased continuously may be due to the Eurozone crisis and the euro's depreciation against the US dollar. Then we show that the US dollar dominates as an anchor currency, though it was temporary abandoned during crisis time, having more than a regional dimension. At the same time, the use of the euro in exchange rate arrangements appears mainly in the regions that have close links with the euro area. Over the last few years, we have witnessed a gentle orientation towards a multimonetary world, especially regarding the use of the international currencies as reserve currency given the diversification of the currencies in which central banks understand to hold international reserves and the increasing share of the nontraditional currencies in total foreign exchange reserves.

Cross currency swaps are powerful instruments to transfer assets or liabilities from one currency into another. The market charges for this a liquidity premium, the cross currency basis spread, which should be taken into account by the valuation methodology. We describe and compare two valuation methods for cross currency swaps which are based upon using two different discounting curves. The first method is very popular in practice but inconsistent with single currency swap valuation methods....

A free-floating currency regime during economic crisis: advantage or disadvantage?

Directory of Open Access Journals (Sweden)

Lubor Lacina

2011-01-01

Full Text Available The paper deals with the identification of potential disadvantages associated with the existence of national currencies with the floating exchange rate regime during the current financial and economic crisis in countries postponing their entry into the eurozone. The hypothesis is that the advantages of a floating exchange rate may be outweighed by their disadvantages (high volatility of exchange rates. First part of the paper provides evidence about the development of Czech crown exchange rate since transition from fix to free float regime. Special attention will be given to the period during the recent global economic crisis. For the sake of comparison, evolution of other currencies in the region (zloty, forint and Slovak crown, will be taken to consideration. Second part of the paper form case studies identifying impact due to volatility on national currencies. Case studies were used to identify possible negative impacts from volatility in national currencies on export firms in the Czech Republic and holders of mortgage loans denominated in foreign currencies in Hungary. The last part of the paper will formulate recommendations for businesses entering into foreign trade relationships, as well as for policy makers in countries using national currencies which are preparing for membership in the eurozone.

The Determinants of Banking Crises and Currency Crises

Directory of Open Access Journals (Sweden)

Young Mok Bae

2005-06-01

Full Text Available This paper studies the factors associated with the emergence of banking crises and currency crises and the interrelationship between the two crises in 21 American, European and Asian countries in 1973~2000 using a multivariate logit econometric model. And this analysis attempts to introduce the lag model to solve the causality problems in banking crises and currency crises. In case of the simple binary models without lag, banking crises were associated with economic recession, inflation, depreciation, the rise of real interest rate, lending boom. But in case of lag models, banking crises were caused by economic recession, inflation, the rise of real interest rate, lending boom, the rise of reserve ratio, the liberalization of capital account. Currency crises were associated with economic recession, the larger deficit of current account relative to import in case of the simple binary models without lag, But in case of lag models, currency crises were caused by economic recession, the rapid decrease of net foreign assets of banks, and the larger deficit of current account relative to import. And this analysis shows that currency crises can be a cause of banking crises, not vice versa. Nevertheless the two types of crises have positive correlation with each other.

China-U.S. Currency Conflict:The Economic and Legal Implications

Directory of Open Access Journals (Sweden)

Hani Albasoos

2016-10-01

Full Text Available Abstract: For more than a decade, China has a policy of managing its currency exchange rate (RMB to limit its appreciation against other currencies like U.S dollar. This policy has been subjected to many criticisms from United States’ lawmakers as currency manipulation. The U.S. argues that China is gaining an advantage of export and attracting direct foreign investment at the expense of other countries including the United State. The claim also has included that China’s manipulation causes U.S. trade deficit as well as high rate of unemployment. Meanwhile, China’s policy makers argue that its policy of exchange rate is a mechanism tool to enhance the development of the country and attaining market growth to make China rich and powerful. This research paper underlines the root of this argument and how china’s currency policy has affected both economics of U.S. and China. Many economists have emphasized on the appreciation of RMB as an important factor to attain the trade balance. However, this research argues that the appreciation is not going to matter. Pressure has been put on Obama’s Administration to push China to appreciate its currency and to designate China as a "currency manipulator". Several Bills have been introduced to discuss this issue. From a legal perspective, two entities could tackle this issue. They are the World Trade Organization (WTO and the International Monetary Fund (IMF. However, IMF lack legitimacy and leverage and WTO has no jurisdiction over the exchange rate. So, none of these entities could handle the currency issue. Therefore, this paper analyzes some possible solutions such as Omnibus Act, tariffs, import quotas and forming new legislation. Where, it concludes that the best solution could be via forming a new international agency.

The Third Currency War as an Effect of Post-Crisis Changes in the International Currency System. The Risk Aspect - the Case Analyses of Brazil

Directory of Open Access Journals (Sweden)

Jacek Pera

Full Text Available Aim/purpose - The objectives of the paper include: identification of factors that influence the directions of fluctuations of foreign exchange rates seen as manifestations of currency wars; description of the most important forms of currency wars conducted in the contemporary global economy (including in particular the currently observed third currency war; analysis of risks to contemporary financial markets and national economies posed by the third currency war. Design/methodology/approach - The paper uses the method of critical analysis of the literature on the subject, as well as US-China and Brazil case analyses. The Propensity Score Matching method was used in the study. Findings - The research findings confirmed the following hypotheses: contemporary fluctuations of foreign exchange rates in the largest economies of the world confirm that the third currency war is ongoing; the risk of consequences of the currency war destabilises the international and local financial markets and trade transactions among them. Research implications/limitations - The limited scope of the research performed is due to the fact that emerging economies have no control of devaluation or revaluation processes in their respective countries. However, large economies, such as China or Japan, are able to create the value of their respective currencies, thus artificially controlling the competitiveness of their products and services. These differences between small and large economies limit and distort the scope of the research done.

Full Text Available Development of the country’s market national economy is closely connected with international economic relations. Therefore national business entities are actively involved in foreign trade, and their positive results influence not only on the status and income of owners, but form the economic potential of the country. The survey describes the main indicators of foreign trade and the impact of export and import transactions on economic development of Ukraine, particularly on the gross domestic income of the country. Taking into account also the negative trends in foreign currency exchange rates, the article considers the types of currency risks that accompany international transactions and identifies the limits of the usefulness of currency risk management methods. The methods of currency risk management are also systematized, the benefits of their use for the enterprise are considered and the status and readiness of Ukraine’s financial market to ensure appropriate conditions for the functioning of the currency risk management in domestic enterprises are analyzed.

Currency Crisis in Sudan in 2012: An Econometric Analysis

Directory of Open Access Journals (Sweden)

Alamedin Bannaga, Dr.

2015-06-01

Full Text Available The Sudan currency crisis in 2012 occurred when the Sudanese pound lost 66 percent of its value against the US dollar. In this article we adopt statistical methods such as the signal approach and econometric methods such as the Probit Model for identifying and evaluating the currency crisis. We utilize some economic indicators that have the ability to predict the crisis. We examined the capability of these indicators in generating an early warning system for Sudan currency crisis. The study confirms that the incidence of currency crisis in Sudan increases by increase in inflation rate, increase in import percentage of GDP, rise in claims against the central government, reduction in external reserves and existence of political crisis. Moreover, the study finds that the most important predictor of currency crisis in Sudan is decline in external reserves.

The euro: an international currency

A number of studies and reports are now readily available on how to come grips the Euro - its calendar, conversion factors, legal, financial and accounting aspects, and so forth. Typically, they point to a fixed-for-ever rate of exchange between participating countries, which of course may have strategic consequences for the location of many types of business. This survey does not seek to be exhaustive, nor to cover what is well documented elsewhere. Rather, it attempts to examine areas where uncertainty, or controversy continue to exist, as well as focus on aspects that are pertinent to the oil and gas industries. Two questions stand out. The first is a general one, concerning how the Euro is likely to fare in international currency markets, notably relative to the US Dollar. The second is closely linked to the first, but is specific to the hydrocarbons business: will European oil and gas prices be quoted in euros and, if so, over what time frame? Finally, this review looks briefly at a selection of other impacts relevant to the energy business

Full Text Available My thesis is that, in the “age of markets” in Europe the Euro is of central importance for creating (or destroying already established structures of European identity (at least in parts of Europe – with Great Britain taking a very remote position. I emphasize the theoretical aspects (Aftalion´s Psychological Theory of Exchange Rates; Simmel: Philosophie des Geldes to emphasize the importance of PR. I concentrate on historical cases – mainly German experiences – e.g. the campaign against the Rubel; the ideas of Ivy Lee; the PR-campaigns of the Nazi-government to fight inflation. The introduction of the German Mark (“die Deutsche Mark”, which became a central aspect of German national identity, and the campaign to give up this currency (“harte Währung” in order to introduce the “weak” Euro. In this context I discuss campaigns against the Euro (“only idiots want the Euro”. In the final remarks I refer to the role of rating agencies and trust in currencies and countries. It is my thesis that the analysts of the rating agencies live in a “world of literary images” and are acting in a completely irresponsible way (but even more incompetent are the politicians accepting the ratings without knowing anything about the problem of commensuration.

The methodology of comparative evaluation of ruble and foreign currency loans in the pre-crisis period

Chamov Aleksey Nikolaevich

2016-04-01

Full Text Available In the article the author considers a problem of an optimal way of borrowing during the pre-crisis period (deciding between ruble and foreign currency borrowings. It is obvious that during the period of stable economic growth, when currency pair rate (for example, ruble - USA dollar doesn't change significntly, the lower interest rate of foreign currency loans makes them a cheaper way of borrowing. But during a crisis an abrupt growth of currency pair rate can make foreign currency loan a more expensive way of borrowing (as compared to ruble loan. The author suggests a scenario-based method of decision making about an optimal way of borrowing during a pre-crisis period, which affords to calculate a threshold meaning of currency pair rate, after which a foreign currency loan becomes more expensive. Application of the method is illustrated on the example of a situation in a telecommunication sector in Russian Federation during currency crisis of 2014. A detailed analysis if the situation in the sector in the last pre-crisis year (2013 is provided. Structures of debt burdens of the leading companies (Vimpelcom, MTS and Megafon are considered.

Nitsch, Volker

2005-01-01

Recent research suggests that adopting a common currency increases bilateral trade. In this paper, I explore experiences of currency union entry in the post-war period and find no effect on trade. Previous results derived from a large panel data set (covering more than 200 countries from 1948 through 1997) appear to depend crucially on the assumption of symmetry between currency union exits and entries: While countries leaving a currency union experience significant declines in trade, currenc...

Full Text Available The ASEAN Economic Community (AEC will be shaped developing to be a single market and production base in 2015, moving towards regional Economic Integration, 2009. These developments in international financial markets do lead to some adverse cost for AEC country borrowers. The specific objective aims to investigate the dependent measures and the co-movement among selected ASEAN currencies. A Copula Approach was used to examine dependent measures of Thai Baht exchange rate among selected ASEAN currencies during the period of 2008-2011. Also, a Dynamic Copula Approach was tested to investigate the co-movement of Thai Baht exchange rate among selected ASEAN currencies during the period of 2008-2011. The results of the study based on a Pearson linear correlation coefficient confirmed that Thai Baht exchange rate and each of selected ASEAN currencies have a linear correlation during the specific period excluding Vietnam exchange rate. Furthermore, based on empirical Copula Approach, Thai Baht exchange rate had a dependent structure with each of the selected in ASEAN currencies including Brunei exchange rate, Singapore exchange rate, Malaysia exchange rate, Indonesia exchange rate, Philippine exchange rate, and Vietnam exchange rate respectively. The results of Dynamic Copula estimation indicated that Thai Baht exchange rate had a co-movement with selected ASEAN currencies. The research results provide an informative and interactive ASEAN financial market to all users, including Global financial market.

We study the correlations of exchange rate volatility in the global foreign exchange(FX) market based on complex network graphs. Correlation matrices (CM) and the theoretical information flow method (Infomap) are employed to analyze the modular structure of the global foreign exchange network. The analysis demonstrates that there exist currency modules in the network, which is consistent with the geographical nature of currencies. The European and the East Asian currency modules in the FX network are most significant. We introduce a measure of the impact of individual currency based on its partial correlations with other currencies. We further incorporate an impact elimination method to filter out the impact of core nodes and construct subnetworks after the removal of these core nodes. The result reveals that (i) the US Dollar has prominent global influence on the FX market while the Euro has great impact on European currencies; (ii) the East Asian currency module is more strongly correlated than the European currency module. The strong correlation is a result of the strong co-movement of currencies in the region. The co-movement of currencies is further used to study the formation of international monetary bloc and the result is in good agreement with the consideration based on international trade.

Full Text Available Background: Paper currency is used in exchange for services, and thisis why the circulation of paper currency from person to person expandsmicroorganisms. Objectives:: Paper banknotes would be a vector for transmission of pathogenic microorganisms through handling. This study aimed to determine bacterial contamination of Iranian paper currencies in circulation and their antibiotic resistance patterns. Materials and Methods: In this study, 337 currency notes of different value were collected from markets, shops, restaurants, bus stations and banks in Kashan, Iran during April 2015 to March 2016. The currency notes transferred to microbiology laboratory and were tested for bacterial contamination using standard microbiological methods. Antibiotic resistance patterns of isolated bacteria were determined by disk diffusion method according to CLSI standards. The results and data were analyzed using descriptive statistics. Results: Of 337 currency notes, 262 (77.7% were identified with bacterial contamination. Bacteria isolated from currency notes were as follows: Bacillus spp 113 (43.1%, coagulase-negative Staphylococci 99 (37.7%, Escherichia coli 20 (7.6%, Enterococci species 14 (5.3%, Staphylococcus aureus 8 (3.1%, Klebsiella spp 4 (1.5%, Shigella species 2 (0.8%, Pseudomonas species 2 (0.8%. The most and least contaminated currency notes were 50000 and 500 Rials, respectively. The most resistance rates in gram negative rods were against nalidixicacid, and ampicillin. Also most resistance rates in Staphylococcus aureus, coagulase-negative Staphylococci and Enterococci species were against ampicillin, erythromycin and tetracycline. Conclusion: Our study revealed that the bacterial contamination among Iranian paper currency in circulation especially those obtained from certain sources including shops and bus stations is high and in most cases these bacterial isolates are antibiotic resistant strains.

Full Text Available In this paper the trends of exchange rates for the foreign currency are studied yearly for Pakistan rupee. In 2000 State bank of Pakistan officially floated the rupee. In this studies the trends of the exchange rate before floating and after floating and then checks its impact on the GDP per capita of the country. Here we consider the daily data of exchange rates of Pakistani currency from 1995 to 2009. Data was analyzed from 1995 to 2000 in the first step. In the second step data from 2001 to 2009 was analyzed. The result shows that if one wants to fl oat currency he must keep in mind that the political condition or stable and that the economy is also stable so that the system of fl oat can perform its functions completely.

Usmanova, Vasilya; Lysogorskiy, Yury V.; Abe, Sumiyoshi

2018-02-01

The dynamical behavior of the currency exchange rate after its large-scale catastrophe is discussed through a case study of the rate of Russian rubles to US dollars after its crash in 2014. It is shown that, similarly to the case of the stock market crash, the relaxation is characterized by a power law, which is in analogy with the Omori-Utsu law for earthquake aftershocks. The waiting-time distribution is found to also obey a power law. Furthermore, the event-event correlation is discussed, and the aging phenomenon and scaling property are observed. Comments are made on (non-)Markovianity of the aftershock process and on a possible relevance of glassy dynamics to the market system after the crash.

The theory of an ‘optimum currency area’

Directory of Open Access Journals (Sweden)

Jarosław Kundera

2012-12-01

Full Text Available The main goal of this paper is to analyse and distinguish the main components of the theory of an ‘Optimum Currency Area’. The theory of an optimum currency area indicates some essential elements as preconditions for the successful introduction of a common currency: high mobility of labour, openness of the economy defined as a high proportion of tradable to non-tradable goods, and high diversification of domestic production before joining the union. The article’s analysis helps to better understanding the reasons of the current crisis in the euro zone. The main problem with a common currency area is the adjustment to imbalances, which cannot take place through exchange rates in conditions of a common currency. The missing elements of the theory are the role of the mobility of capital to correct interregional balance of payments disequilibria and lack of a common budget with sufficient own resources during the occurrence of debt crises in member countries. The theory of an optimum currency area has noticed the importance of coordination between fiscal and monetary policy and the necessity of redistribution of resources among partners. However, it does not say much about the methods applied, how to deal with debt crises and what the cost of a potential breaking up of monetary union would be.

Horváth, D.; Pincak, R.

2012-11-01

In the paper, we study the projections of the real exchange rate dynamics onto the string-like topology. Our approach is inspired by the contemporary movements in the string theory. The string map of data is defined here by the boundary conditions, characteristic length, real valued and the method of redistribution of information. As a practical matter, this map represents the detrending and data standardization procedure. We introduced maps onto 1-end-point and 2-end-point open strings that satisfy the Dirichlet and Neumann boundary conditions. The questions of the choice of extra-dimensions, symmetries, duality and ways to the partial compactification are discussed. Subsequently, we pass to higher dimensional and more complex objects. The 2D-Brane was suggested which incorporated bid-ask spreads. Polarization by the spread was considered which admitted analyzing arbitrage opportunities on the market where transaction costs are taken into account. The model of the rotating string which naturally yields calculation of angular momentum is suitable for tracking of several currency pairs. The systematic way which allows one suggest more structured maps suitable for a simultaneous study of several currency pairs was analyzed by means of the Gâteaux generalized differential calculus. The effect of the string and brane maps on test data was studied by comparing their mean statistical characteristics. The study revealed notable differences between topologies. We review the dependence on the characteristic string length, mean fluctuations and properties of the intra-string statistics. The study explores the coupling of the string amplitude and volatility. The possible utilizations of the string theory approach in financial markets are slight.

A stable world currency exchange rate is a very important aspect to be considered for a developed country, i.e Malaysia. A better understanding about the currencies itself is needed nowadays. This project is about to understanding the fluctuation and to identify the most influential world currencies in the three different cases; before credit crisis, during credit crisis and after credit crisis. A network topology approach is use to examine the interrelationship between currencies based on correlation analysis. With this point of view, those relationships can be measured by a correlation structure among the currencies. The network can be analyse by filtering the important information using minimum spanning tree (MST) and interpret it using degree centrality as the centrality measure. This topology will give a useful guide to understand the behaviour and determine the most influential currency in the network as a part of a complex system. All currencies are compared among the three different cases; before credit crisis, during credit crisis and after credit crisis period. The result of this project shows that Unites State Dollar (USD), Brazilian Real (BRL), United Kingdom Pound (EUR) and Danish Krone (DKK) are the most influential currencies before the credit crisis period. With respect to during the credit crisis, New Zealand Dollar (NZD) dominates the network and it is followed by Singapore Dollar (SGD) for after the credit crisis period.

A large set of daily FOREX time series is analyzed. The corresponding correlation matrices (CM) are constructed for USD, EUR and PLN used as the base currencies. The triangle rule is interpreted as constraints reducing the number of independent returns. The CM spectrum is computed and compared with the cases of shuffled currencies and a fictitious random currency taken as a base currency. The Minimal Spanning Tree (MST) graphs are calculated and the clustering effects for strong currencies are found. It is shown that for MSTs the node rank has power like, scale free behavior. Finally, the scaling exponents are evaluated and found in the range analogous to those identified recently for various complex networks.

Full Text Available Currency options are often used to mitigate currency risk resulting from corporate activities. Their implementation can be complex, and there could be problems if the essential elements and principles are not fully understood. Although they are not the simplest financial products, currency options are interesting and useful to those who are trying to make a step forward in the area of currency risk management. This paper aims to present the general principles and specifics of accounting records and valuation of currency options used for hedging against risk. It is a complex process which, in addition to numerous conditions, also involves the implementation of accounting rules that deviate from the generally accepted accounting principles.

Influencing Factors of Currency Risk of Deposit Banks in Turkey by Using Probit Method

Serhat Yüksel

2016-12-01

Full Text Available In this paper, we aimed to analyze the factors that affect currency risk of the banks. Within this scope, annual data of 23 deposit banks for the periods between 2005 and 2015 was evaluated. In addition to this situation, panel probit model was used in order to achieve this objective. Regarding the subject of the currency risk, this model was firstly used in this study. According to the results of the analysis, it was determined that 3 independent variables affect the currency risk of deposit banks in Turkey. Firstly, it was identified that there is a positive relationship between total assets and currency risk. This situation explains that when the size of the banks increases, they tend to take more currency risk. In addition to this variable, it was also defined that there is a direct relationship between economic growth and currency risk of the banks. This result refers that in case of an increment in the market stability; banks think that the market is safer and they increase their currency risk. Moreover, it was also concluded that there is a negative relationship between interest rate and currency risk of the banks. This aspect shows that when interest rate decreases, it will lower uncertainty in the market. Thus, banks would take higher currency risk in such markets.

Scale free effects in world currency exchange network

Science.gov (United States)

Górski, A. Z.; Drożdż, S.; Kwapień, J.

2008-11-01

A large collection of daily time series for 60 world currencies' exchange rates is considered. The correlation matrices are calculated and the corresponding Minimal Spanning Tree (MST) graphs are constructed for each of those currencies used as reference for the remaining ones. It is shown that multiplicity of the MST graphs' nodes to a good approximation develops a power like, scale free distribution with the scaling exponent similar as for several other complex systems studied so far. Furthermore, quantitative arguments in favor of the hierarchical organization of the world currency exchange network are provided by relating the structure of the above MST graphs and their scaling exponents to those that are derived from an exactly solvable hierarchical network model. A special status of the USD during the period considered can be attributed to some departures of the MST features, when this currency (or some other tied to it) is used as reference, from characteristics typical to such a hierarchical clustering of nodes towards those that correspond to the random graphs. Even though in general the basic structure of the MST is robust with respect to changing the reference currency some trace of a systematic transition from somewhat dispersed - like the USD case - towards more compact MST topology can be observed when correlations increase.

Forecasting of Currency Crises in East Asia

Directory of Open Access Journals (Sweden)

Chi-Young Song

2005-06-01

Full Text Available In this paper, we have developed a forecasting system for currency crisis in East Asia based on a signaling approach. Our system uses 15 monthly indicators of five East Asian countries including Indonesia, Korea, Malaysia, the Philippines and Thailand that were severely hit by the currency crisis in 1997. We investigate the performance of the system through deploying out-of-sample forecasting for the periods both before and after the 1997 East Asian currency crisis. Unlike the existing research based on the signaling approach, our out-of-sample forecasting does not fix the in-sample period. The out-of-sample forecasting between July 1995 and June 1997 shows that prior to breakout of the crisis, several indicators including real exchange rates and exports sent frequent warnings to all crisis-hit East Asian countries except the Philippines. This may indicate that a signaling-based early warning system for currency crisis could have been an useful method of forecasting the East Asian crisis. On the other hand, we also find that our forecasting system often generates warning signals during the out-of-sample period between July 1999 and June 2001. Since we have not observed any currency crisis in this region after 1998, these are all false alarms, indicating that our system may be seriously exposed to the type II error. We can, however, mitigate this problem if we adjust the optimal critical values of indicators depending on the preferences of forecasting system manager.

International business of banking: the pricing example of retail currency spreads

2013-05-01

Full Text Available In this paper the pricing of a specific service of currency exchange based on the retail exchange rate spreads is studied on the example of four international banking groups. The aim of this study is to explore pricing of currency exchange services based on bid-ask differences in some commercial banks and possible price discrimination in this segment of market comparing the behaviour of Western mothers and Eastern daughters in European international banking groups. The retail currency rate spreads in different bank groups and countries are compared with each other. The main results of the study are that statistically significant differences exist in the spreads set by banking groups in different countries. All banking groups in the pilot sample offer more favourable rates in Western countries indicating that the pricing policy of bank groups may be discriminatory. The volatility of spreads over different currencies suggests that different decision making mechanisms may be present in the groups depending on the location of banking unit. The results of this pilot study suggest that further research is needed to understand the extent and the mechanism of findings.

The optimal currency-peg for an oil exporting country: The case of Saudi Arabia

International Nuclear Information System (INIS)

Almasbahi, M.S.

1990-01-01

In a world of generalized floating exchange rates, it is not enough to solve the problem of exchange rate policy by determining whether to peg or float the currency under consideration. It is also necessary to choose to what major currency to peg. The main purpose of this study is to investigate and determine empirically the optimum currency peg for the Saudi riyal. To accomplish this goal, a simple conventional trade model, that includes variables found in many other studies of import and export demand, was used. In addition, an exchange rate term was added as a separate independent variable in the import and export demand equations in order to assess the effect of exchange rate on the trade flows. The criteria for the optimal currency peg in this study were based on two factors. First, the error statistics for projected imports and exports using alternative exchange rate regimes. Second, variances of projected imports, exports and trade balance using alternative exchange rate regimes. The exchange rate has a significant impact on the Saudia Arabian trade flows which implies that changes in the riyals value affect the Saudi trade deficit. Moreover, the exchange rate has a more powerful effect on its aggregate imports than on the world demand for its exports. There is also a strong support for the hypothesis that the exchange rate affects the value of the Saudi bilateral trade with its five major trade partners. On the aggregate level, the SDR peg seems to be the best currency peg for the Saudi riyal since it provides the best prediction errors and the lowest variance for the trade balance. Finally, on the disaggregate level, the US dollar provides the best performance and yields the best results among all the six currency pegs considered in this study

Full Text Available This study attempts to test the conditional version of the international asset-pricing model proposed in Bayraktar (2000, 2009 by using a parsimonious multivariate GARCH process. The theoretical model, contrary to previous empirical studies that have used random selection of currency risks, determines which currencies should be included in an empirical test, thus avoids this kind of random selection bias. The results from both full and sub-samples regressions provide some weak evidence for the existence of exchange rate risks, thus partially support the theory. However, exchange rate risks' premia are found considerably smaller than that of market risk.

Are pound and euro the same currency?

2007-01-01

Based on long-range dependence, some analysts claim that the exchange rate time series of the pound sterling and of an artificially extended euro have been locked together for years despite daily changes [M. Ausloos, K. Ivanova, Physica A 286 (2000) 353; K. Ivanova, M. Ausloos, False EUR exchange rates vs DKK, CHF, JPY and USD. What is a strong currency? in: H. Takayasu (Ed.), Empirical Sciences in Financial Fluctuations: The Advent of Econophysics, Springer-Verlag, Berlin, 2002, pp. 62-76]. They conclude that pound and euro are in practice the same currency. We assess the long-range dependence over time through Hurst exponents of pound-dollar and extended euro-dollar exchange rates employing three alternative techniques, namely rescaled range analysis, detrended fluctuation analysis, and detrended moving average. We find the result above (which is based on detrended fluctuation analysis) not to be robust to the changing techniques and parameterizing

This project entailed studying the cellulose in paper, the ink, colorants, and other materials used to produce American colonial currency. The technique primarily used in this project was X-Ray Fluorescence Spectroscopy (XRF). XRF mapping was used to provide both elemental analysis of large-scale objects as well as microscopic examination of individual pigment particles in ink, in addition to the inorganic additives used to prepare paper. The combination of elemental mapping with Fourier Transform Infrared (FTIR) and Raman Spectroscopies permits an efficient analysis of the currency. These spectroscopic methods help identify the molecular composition of the pigments. This combination of atomic and molecular analytical techniques provided an in-depth characterization of the paper currency on the macro, micro, and molecular levels. We have identified several of pigments that were used in the preparation of inks and colorants. Also, different inorganic crystals, such as alumina-silicates, have been detected in different papers. The FTIR spectroscopy allowed us to determine the type of cellulose fiber used in the production of paper currency. Our future research will be directed toward revealing important historical relationships between currencies printed throughout the colonies. ISLA Da Vinci Grant.

Full Text Available Optimization of currency portfolio structure of export industrial enterprises in the Republic of Belarus, by which we shall understand a currency structure of export contracts of an international enterprise, is considered as one of the most important problems in the financial management of an enterprise. Statement and analysis of industrial enterprise alternative costs and simultaneous investigation of tendencies pertaining to changes in the exchange rates give the possibility (under other equal status to reduce non-systematic risks in foreign trade. Diversification of industrial enterprise currency portfolios with the purpose to decrease financial risks and with due account of exchange rate correlation can lead to an increase of payments in Russian currency and Eurocurrency under enterprise export contracts. The given changes decrease currency risks in the foreign trade however they entail possible increase of the export share of products to the Russian Federation in total export volume of the Republic of Belarus that increases dependence of the Republic of Belarus on the Russian Federation as the main foreign trade partner.

Ist der Euro gefährdet? Is the European currency euro put at risk?

Armin Rohde

2012-01-01

Full Text Available Due to high national debt in several member states of the Euro-Currency-Area which led to huge relief programmes the single European currency Euro seems to be at risk. Bur neither inflation rates nor exchange rate movements of the Euro since 1999 up to 2011 give reasons to believe that an up to now success story of the Euro will come to a sudden end in shortness. On the other hand it often had been argued that increasing national debt will inevitably lead to higher inflation rates and will endanger a currency by permanent devaluation. But the institutional and legal framework of the European monetary policy, if used correctly, will give sufficient protection against inflation pressure due to increasing national debt. The most danger for the European currency or for the European-Currency-Area can be seen in drifting apart of national competiveness between the member states of the Euro- Area, especially due to an existing lack of coordination in wage policy. Different wage policies in the member states of the Euro-Area in the past had led to different national inflation rates and had caused calculated real exchange rate movements which had lasting influence on national competiveness, which hamper international trade in the case of real appreciation or which promote international trade in the case of real depreciation..

Gold, currencies and market efficiency

Science.gov (United States)

Kristoufek, Ladislav; Vosvrda, Miloslav

2016-05-01

Gold and currency markets form a unique pair with specific interactions and dynamics. We focus on the efficiency ranking of gold markets with respect to the currency of purchase. By utilizing the Efficiency Index (EI) based on fractal dimension, approximate entropy and long-term memory on a wide portfolio of 142 gold price series for different currencies, we construct the efficiency ranking based on the extended EI methodology we provide. Rather unexpected results are uncovered as the gold prices in major currencies lay among the least efficient ones whereas very minor currencies are among the most efficient ones. We argue that such counterintuitive results can be partly attributed to a unique period of examination (2011-2014) characteristic by quantitative easing and rather unorthodox monetary policies together with the investigated illegal collusion of major foreign exchange market participants, as well as some other factors discussed in some detail.

On the World and Regional Currencies

Rohach Fedir I.

2016-05-01

Full Text Available The problem of pegging currencies of developing countries to the US dollar is that its dynamics determines the economic instability of most of such countries and the world economy as a whole. In this regard there is a need to find alternative variants of the global monetary anchor to ensure the global financial stability. It is proposed to choose an anchor based on the basket of floating national currencies, which will be balanced by counter fluctuations of the basket currencies and be stable with respect to the national currency, as one of the variants. Such basket anchor can potentially perform the function of money and be used as the world and regional currency. The article presents the example of calculating the quotation of national currencies against the baskets based on the data on G-20 and EAEU countries.

It also contains research and analysis of HSBC's operations in different countries in the devaluation race grouping them according to the participation in currency wars. Along with the benefits of the devaluation of its own currency the actual disadvantages that may reveal afterwards have been identified. This article highlights the different versions of events put forward by the experts in the global economy and analysts. The authors mention the possible problems of ordinary citizens in case of their country's aggressive policy to reduce their national currency. The behavior of the Russian ruble was also discussed in detail according to which the recommendations were given to depositors of banks about their future action in the circumstances. Devaluation race in any case cannot be completed safely but it is possible to avoid excessive losses if the countries achieve international agreement by establishing a new currency regime.

NEGATIVE CURRENCY-RISK-EXPOSURE FOR TURKISH EQUITIES

Directory of Open Access Journals (Sweden)

Salvatore J. Terregrossa

2016-04-01

Full Text Available Currency-risk-exposure is an issue for Turkish equities, from two different angles: internationaltrade and foreign-portfolio-investment. The likely effect is positive for the former, and negative for the latter aspect. Consequently, the overall or net effect on equity value depends on which of these aspects of currency-risk-exposure has the greater impact. The present empirical analysis estimates currency risk of Turkish equities within a multi-factor regression setting, utilizing the framework of the Security Market Plane (SMP model. The SMP model embodies a conditional relation among three variables: beta, realized excess market-return, and expected excess portfolio-return. The SMP empirical framework is extended to include a currency-risk-factor in the present analysis. The currency-risk-factor is specified as the excess return to holding foreign currency (€; $, relative to holding domestic currency (Turkish Lira. The SMP-related factor is the cross-product term of beta and realized excess market-return (β it rMt . A regression of realized excess portfolio-returns against the corresponding currency-risk-factor and cross product-term (β it rMt finds that the Turkish stocks represented in the analysis generally have overall negative currency-risk-exposure; suggesting that unexpected currency depreciation generally leads to lower values for Turkish stocks (and portfolios of Turkish stocks. Thus, after accounting for the SMP-related interaction-effect between beta and realized excess marketreturn, currency risk is found to command a premium for the Turkish stocks represented in the analysis.

We study endogenous currency substitution in a decentralized trade environment. Sellers maximize profits from sales of imperfectly substitutable goods by posting prices in either one of two currencies. A unique symmetric equilibrium exists where goods are priced only in the local currency. This occurs if foreign trade is sporadic, there is sufficient but not excessive liquidity, and discounting is low. Excess or scarcity of liquidity, however, induces sellers to extract all surplus from bu...

2014-06-01

Full Text Available The present paper presents the models used by the countries that joined the Euro zone after 2000, in fixing the central parity and the evolution of the local currency towards Euro, when participating in Exchange Rate Mechanism II (ERM II. It synthesizes the main theories for determining the equilibrium exchange rate. It also presents the modality of putting them into practice in the countries that had already become members of the Euro zone. The better we know the other countries’ experience in the respect of the joining process to the Euro zone, the better will Romania be able to prepare itself for adopting the unique European currency. Thus, we will be synthesize the main approaches within literature and also in the economic policy deciders’ practice concerning the estimation of the equilibrium exchange rate and implicitly, of the central parity. The paper presents the modality of fixing the central parity and the experience of participating in ERM II for a number of member states that joined the Euro zone after 2000: Greece, Slovakia, Slovenia, Malta, Cyprus and Estonia. For these states we also analyze the evolution of the currency towards Euro while participating in ERM II. Starting from these examples, we explain the advantages and the disadvantages in fixing the central parity over/at/under the value of the exchange rate on the market at the moment of joining ERM II and we underline the problems that might occur in the case of choosing a central parity that is not compatible with the equilibrium value of the exchange rate.

An attempt to categorize Hungarian community currencies

Directory of Open Access Journals (Sweden)

Eszter Szemerédi

2018-04-01

Full Text Available Since the emergence of complementary currencies in the 1980s there have been numerous attempts to classify them, despite that the terms local currency, community currency and many others describing place-based monetary tools are not considered similarly by scholars. The local currencies take many forms, and local governments play different roles in their emergence and development. In Hungary there has been an increasing attention and discussion around the idea of implementing these alternative monetary tools. There is a growing number of working complementary currencies in Hungary, but academic research focuses mostly on whether these can contribute to the local development and what kind of effects they have. The aim of this paper is to present a possible categorization of Hungarian complementary currencies based on the role local governments played in their implementation. I evaluate whether these community currencies are effective at first, and attempt to categorize them based on their purpose, association form and their relationships with local governments, with the purpose of increasing awareness for these initiatives in the process of policy-making.

Improvement of attitude of many countries to the considered cryptocurrency, in particular the USA, Germany, Spain, Canada, Australia, Israel and Scandinavian countries has been identified. The reasons of Ukraine’s interest in Bitcoin have been considered. Possibilities of creation of cryptocurrency on the territory of Ukraine have been analyzed, i.e. cost of electricity for mining, the legal status of mining firms, and the attitude of the National Bank of Ukraine to the digital currency. It has been concluded that the recognition of Bitcoin by the world countries in the future will allow it to be granted the status of world-wide currency.

Polish Toxic Currency Options

Full Text Available Toxic currency options are defined on the basis of the opposition to the nature (essence of an option contract, which is justified in terms of norms founded on the general law clause of characteristics (nature of a relation (which represents an independent premise for imposing restrictions on the freedom of contracts. So-understood toxic currency options are unlawful. Indeed they contravene iuris cogentis regulations. These include for instance option contracts, which are concluded with a bank, if the bank has not informed about option risk before concluding the contract; or the barrier options, which focus only on the protection of bank’s interests. Therefore, such options may appear to be invalid. Therefore, performing contracts for toxic currency options may be qualified as a criminal mismanagement. For the sake of security, the manager should then take into consideration filing a claim for stating invalidity (which can be made in a court verdict. At the same time, if the supervisory board member in a commercial company, who can also be a subject to mismanagement offences, commits an omission involving lack of reaction (for example, if he/she fails to notify of the suspected offence committed by the management board members acting to the company’s detriment when the management board makes the company conclude option contracts which are charged with absolute invalidity the supervisory board member so acting may be considered to act to the company’s detriment. In the most recent Polish jurisprudence and judicature the standard of a “good host” is treated to be the last resort for determining whether the manager’s powers resulting from criminal regulations were performed. The manager of the exporter should not, as a rule, issue any options. Issuing options always means assuming an obligation. In the case of currency put options it is an absolute obligation to purchase a given amount in euro at exchange rate set in advance. On the

Value-at-Risk Analysis for the Tunisian Currency Market: A comparative study

Aymen Ben Rejeb

2012-01-01

Full Text Available The main purpose of this paper is to compare empirically four Value-at-Risk simulation methods, namely, the Variance-Covariance, the Historical Simulation, the Bootstrapping and the Monte Carlo. We tried to estimate the VaR associated to three currencies and four currency portfolios in the Tunisian exchange market. Data covers the period between 01-01-1999 and 31-12-2007. Independently of the used technique, the Japanese Yen seems to be the most risky currency. Moreover, the portfolio diversification reduces the exchange rate risk. Lastly, the number of violations, when they exist, does not generally differ between the simulation methods. Recent evaluation tests were applied to select the most appropriate technique predicting precisely the exchange rate risk. Results based on these tests suggest that the traditional Variance-Covariance is the most appropriate method.

Demystifying Bitcoin: Sleight of Hand or Major GlobalCurrency Alternative?

2014-12-01

Full Text Available Bitcoin, a peculiar crypto-currency has been the loudest buzzword in global finance over the last year or so, both for its spectacular and seemingly robust appreciation trend as well as for more recent equally ostentatious demise. After reviewing the history of bitcoin and specificities of its cyber-construct, this paper adds to the critical analysis of bitcoin as an international currency alternative. Lately, its volatility has been so excessive that it arguably cannot serve as a store of value. In addition, notwithstanding bitcoin's rising if bumpy credibility as a medium of exchange, since it has been immediately converted (by chief vendors in either of the leading world currencies upon payment due to its extraordinary exchange rate volatility, bitcoin's unit of account potential appears to be dubious too. Moreover, bitcoin's next to none correlation with other major currencies' movements renders it unsuitable for managing FX risk or hedging purposes. Finally, having in mind that it lacks formal reserves or deposit-insurance scheme to back it up yet it's also prone to hacking, bitcoin resembles and behaves more like a pyramidal investment vehicle than a global currency alternative. Nevertheless, technology that made it be may still spawn an evolution in the way we posses things, transfer ownership and pay for goods and services in the near IT-ridden future.

After the Fukushima disaster, energy conversion such as nuclear power phaseout and deployment of renewable energy or survival of nuclear power had been actively argued pro and con. Both sides admitted extra costs were needed but their economic effects would be contrary dependent on business state. Under better economy, extra costs would be actual burden of total economy. Under stagnation as was long in Japan at present, extra costs brought about expansion of employment and economy with simulated consumption increase. Industry conversion would occur such industry intensively using power would depreciate and energy conserved industry would grow. Difference of power use intensity between industries made difficult in energy conversion because present Japanese industry constitution was mostly formed based on cheap power cost for industry use. Even taking account of international competition, the same would be true by adjusting finance balance sheet and currency exchange rate. (T. Tanaka)

Are EUR and GBP different words for the same currency?

Science.gov (United States)

Ivanova, K.; Ausloos, M.

2002-05-01

The British Pound (GBP) is not part of the Euro (EUR) monetary system. In order to find out arguments on whether GBP should join the EUR or not correlations are calculated between GBP exchange rates with respect to various currencies: USD, JPY, CHF, DKK, the currencies forming EUR and a reconstructed EUR for the time interval from 1993 till June 30, 2000. The distribution of fluctuations of the exchange rates is Gaussian for the central part of the distribution, but has fat tails for the large size fluctuations. Within the Detrended Fluctuation Analysis (DFA) statistical method the power law behavior describing the root-mean-square deviation from a linear trend of the exchange rate fluctuations is obtained as a function of time for the time interval of interest. The time-dependent exponent evolution of the exchange rate fluctuations is given. Statistical considerations imply that the GBP is already behaving as a true EUR.

Cognitive processing of currency: Euros and Dollars.

Science.gov (United States)

Macizo, Pedro; Morales, Luis

2015-11-01

In the current study, we evaluated whether the processing of currency was determined by familiarity of people with banknotes. In Experiment 1, participants who used the Euro currency named sequences of Euro banknotes and Dollar banknotes blocked by category or mixed with exemplars of other categories. The participants showed an interference effect in the blocked context with Dollar banknotes but not with Euro banknotes. In Experiment 2, the interference effect was observed with Euro banknotes when participants were not familiar with the Euro currency. These results suggest that the semantic processing of banknotes depends on the participants' familiarity with currency. © 2015 The British Psychological Society.

International Nuclear Information System (INIS)

Clapham, M.; Seamans Jr, J.V.; Arbon, R.E.

2009-01-01

This document describes the methodology developed and used by the Advanced Mixed Waste Treatment Project for determining the activity content and the unshielded surface dose rate for lead lined containers contaminated with transuranic waste. Several methods were investigated: - Direct measurement of the dose rate after removing the shielding. - Use of a MicroShield R derived dose conversion factor, (mRem/hr unshielded )/(mRem/hr shielded ), applied to the measured surface dose rate to estimate the unshielded surface dose rate. - Use of a MicroShield R derived activity conversion factor, mRem/hr unshielded /Ci, applied to the measured activity to estimate the unshielded dose rate. - Use of an empirically derived activity conversion factor, mRem/hr unshielded /Ci, applied to the measured activity to estimate the unshielded dose rate. The last approach proved to be the most efficacious by using a combination of nondestructive assay and empirically defined dose rate conversion factors. Empirically derived conversion factors were found to be highly dependent upon the matrix of the waste. Use of conversion factors relied on activity values corrected to address the presence of a lead liner. (authors)

The quest for sound money: currency boards to the rescue

Some countries with high inflation have adopted another nation’s more stable currency: Panama uses the U.S. dollar, gaining price stability and easier trade with its primary partner. But this arrangement grants an interest-free loan to the government whose currency is used. And the nation using the currency forgoes any income on the foreign currency holdings. ; One alternative, a currency board, achieves the other country’s monetary stability without these costs.

Foreign currency-related translation complexities in cross-border healthcare applications.

Science.gov (United States)

Kumar, Anand; Rodrigues, Jean M

2009-01-01

International cross-border private hospital chains need to apply the standards for foreign currency translation in order to consolidate the balance sheet and income statements. This not only exposes such chains to exchange rate fluctuations in different ways, but also creates added requirements for enterprise-level IT systems especially when they produce parameters which are used to measure the financial and operational performance of the foreign subsidiary or the parent hospital. Such systems would need to come to terms with the complexities involved in such currency-related translations in order to provide the correct data for performance benchmarking.

Cross-correlations between Renminbi and four major currencies in the Renminbi currency basket

We investigate the cross-correlations between Renminbi (CNY) and four major currencies (USD, EUR, JPY, and KRW) in the Renminbi currency basket, i.e., the cross-correlations of CNY-USD, CNY-EUR, CNY-JPY, and CNY-KRW. Qualitatively, using a statistical test in analogy to the Ljung-Box test, we find that cross-correlations significantly exist in CNY-USD, CNY-EUR, CNY-JPY, and CNY-KRW. Quantitatively, employing the detrended cross-correlation analysis (DCCA) method, we find that the cross-correlations of CNY-USD, CNY-EUR, CNY-JPY, and CNY-KRW are weakly persistent. We use the DCCA cross-correlation coefficient ρ to quantify the level of cross-correlations and find the currency weight in the Renminbi currency basket is arranged in the order of USD>EUR>JPY >KRW. Using the method of rolling windows, which can capture the time-varying cross-correlation scaling exponents, we find that: (i) CNY and USD are positively cross-correlated over time, but the cross-correlations of CNY-USD are anti-persistent during the US sub-prime crisis and the European debt crisis. (ii) The cross-correlation scaling exponents of CNY-EUR have the cyclical fluctuation with a nearly two-year cycle. (iii) CNY-JPY has long-term negative cross-correlations, during the European debt crisis, but CNY and KRW are positively cross-correlated.

THE MARKET VALUE OF THE REAL ESTATE IN A SIGNIFICANT DEVALUATION OF THE NATIONAL CURRENCY

Directory of Open Access Journals (Sweden)

VORONIN V. A.

2016-02-01

Full Text Available Raising of problem. The current state of the real estate market is characterized by high inflation and a significant devaluation of national currency. In markets with mixed prices impact of devaluation and inflation against the foreign currency have most complex nature and usually leads to slower growth in prices in local currency and partial de-dollarization of the market. Provided that the value of the real estate market is denominated in local and foreign currency, it is necessary to solve the problem of correspondence between these prices. With this condition must be satisfied that the market prices in local currency correspond to the state of the real estate market on the valuation date. Purpose. Development of the method, which should take into account the particular valuation procedures in determining the market value of the local currency in terms of the existence of high inflation and a significant devaluation. The study of this problem, especially for the markets of emerging economics, is an urgent and important task of applied economic analysis and, in particular, the theory and practice of evaluation as part of this analysis. Conclusion. To achieve this goal have been developed and used techniques and methods of applied economic analysis and, in particular, the theory and practice of evaluation as part of this analysis. Satisfactory agreement obtained values and the market rent rate, which are responsible of the real estate market in a significant devaluation of local currency, confirm the position that the correction in market conditions ("discount on the offer price" and "market conditions" must be done in determining the market value so and the market rent rate.

Monetary policy under currency board arrangements: An necessary flexibility for transition countries?

One of the main disadvantages of currency boards is the rule-based character of this system and the resulting inflexibility in case of shocks, a frequently recurring event in transition countries. Accordingly, central banks under currency board arrangements (CBA) are unable to respond to short-term liquidity changes in the money market. To cushion negative effects of economic shocks on interest rates and on the volatility of banks' liquidity the Estonian and Lithuanian central banks have to a...

Based on the unique characteristic, the paper currency numbers can be put into record and the automatic identification equipment for paper currency numbers is supplied to currency circulation market in order to provide convenience for financial sectors to trace the fiduciary circulation socially and provide effective supervision on paper currency. Simultaneously it is favorable for identifying forged notes, blacklisting the forged notes numbers and solving the major social problems, such as armor cash carrier robbery, money laundering. For the purpose of recognizing the paper currency numbers, a recognition algorithm based on neural network is presented in the paper. Number lines in original paper currency images can be draw out through image processing, such as image de-noising, skew correction, segmentation, and image normalization. According to the different characteristics between digits and letters in serial number, two kinds of classifiers are designed. With the characteristics of associative memory, optimization-compute and rapid convergence, the Discrete Hopfield Neural Network (DHNN) is utilized to recognize the letters; with the characteristics of simple structure, quick learning and global optimum, the Radial-Basis Function Neural Network (RBFNN) is adopted to identify the digits. Then the final recognition results are obtained by combining the two kinds of recognition results in regular sequence. Through the simulation tests, it is confirmed by simulation results that the recognition algorithm of combination of two kinds of recognition methods has such advantages as high recognition rate and faster recognition simultaneously, which is worthy of broad application prospect.

Chávez Muñoz, Pablo; Fernandes da Silva, Marcus; Vivas Miranda, José; Claro, Francisco; Gomez Diniz, Raimundo

2007-12-01

We have studied the performance of the Hurst's index associated with the currency exchange rate in Brazil and Chile. It is shown that this index maps the degree of government control in the exchange rate. A model of supply and demand based in an autonomous agent is proposed, that simulates a virtual market of sale and purchase, where buyer or seller are forced to negotiate through an intermediary. According to this model, the average of the price of daily transactions correspond to the theoretical balance proposed by the law of supply and demand. The influence of an added tendency factor is also analyzed.

Two types of currency crisis models coexist in the literature: first generation models view speculative attacks as being caused by economic fundamentals which are inconsistent with a given parity. Second generation models claim self-fulfilling speculation as the main source of a currency crisis. Recent empirical research in international macroeconomics has attempted to distinguish between the sources of currency crises. This paper adds to this literature by proposing a new empirical approach ...

The analysis of return on speculative trading with futures contracts of agriculture commodities in the context of the currency risk

Oldřich Šoba

2007-01-01

Full Text Available The paper is focused on analysis of return on speculative operations with futures contracts from the view of participators not undertaking and undertaking the currency risk. The currency risk is determined by unexpected change of relevant exchange rate (currency denomination of futures contracts / domestic currency of participator. The paper analyses the basic factors influencing the profitability of these operations such as relative change of futures contract value, leverage incidence and relative change of relevant exchange rate. The paper is focused on futures contracts of the world most important agricultural commodities. The conclusion of the paper for participators not undertaking the currency risk is following: The relative change of futures contract is main factor for the calculation of return on speculative operation. This change is multiplied by leverage incidence finally. The conclusion of the paper for participators undertaking the currency risk is following: The relative change of relevant exchange rate is not usually relevant for the calculation of return on speculative operation. Main factor is the relative change of futures contract because this change is multiplied by leverage incidence finally but the relative change of relevant exchange rate isn’t.Neverthless the conclusions of this paper are not valid only for futures contracts of agricultural commodities but generally also for other commodity futures contracts and futures contracts where underlying assets are not commodities but for example financial assets.

Quantitative analysis of potential currency crisis in the Republic of Serbia

Directory of Open Access Journals (Sweden)

Rađenović Žarko

2015-01-01

Full Text Available The subject of this paper is theoretical and empirical analysis of potential currency crisis in the Republic of Serbia. The main aim of the paper is quantitative analysis of a set of key indicators (index of exchange market pressure, signal-to-noise ratio, misery index, a measure of openness and the monetary measure of openness of the country that indicate the possibility of a currency crisis. The cyclic character of currency and financial crisis is forcing policymakers to conduct thoughtful exchange rate policy. The aim of this is to prevent the scenario with which the countries of Latin America faced in the late 20th century. Although there is no a significant correlation in terms of international trade transactions between Serbia and the countries of Latin America, we should certainly learn from the experience of these countries. It is necessary to continuously monitor the value of indicators which point to possible distortion. In the paper we use some econometric and statistical tools, such as correlation and regression analysis, to point to the values of indicators which can contribute to early detection of a currency crisis.

Causes of the Recent Currency Crises in Developing Economies

Directory of Open Access Journals (Sweden)

Haesik Park

1997-12-01

Full Text Available This thesis analyzed the reasons of foreign currency crisis which happened in Mid-South America and South East Asia based on the economical structure of developing countries. First, it is illustrated theoretically. Since the developing countries, which maintain the export-oriented economic growth, allocates the sources in the trade area, equilibrium real exchange rate of these countries get relatively higher evaluation. Capital inflows with future exports as its necessary conditions make the foreign exchange market participants expect that the real future exchange rate will be much lower than the current equilibrium exchange rate (so called "devaluation", giving rise to foreign exchange crisis. Negative debts result in the information asymmetry between creditor and debtor, and between adverse selection and moral relaxation, and that cause crisis for foreign currency and reduces their attractiveness, proposed by Mishkin. In fact developing countries in Southeast Asia and Central and South America that has the recent outbreak of a foreign exchange crisis, also have unhealthy banks. When we apply analysis mentioned above to South Korea, we can not find evidence of relatively high evaluation level on the real equilibrium exchange rate and evidence of poor management in the banking sector.

This paper argues that the balance of evidence points to a large and statistically significant causal relation...

Relative Effects of the Dollar and Yen on East Asian Currency Values: Focusing on the Post-Crisis Period

Directory of Open Access Journals (Sweden)

Bonghan Kim

2007-06-01

Full Text Available This paper empirically analyzes the relative effects of the dollar and yen on the value of East Asian currencies. We focus especially on countries that have chosen to adopt floating regimes in the post-financial crisis period, such as South Korea, Taiwan, Indonesia, the Philippines and Thailand. First, we calculate a exchange rate flexibility index and carry out a regression using Frankel and Wei's (1994 methodology. The results confirm an increase in the coupling of East Asian currencies vis-a-vis the yen since the 1997 financial crisis. In addition to coupling, we calculate using a non-linear unit root test the exchange rates for four currencies vis-a-vis the yen, excluding the Philippine peso, which has a band-reverting tendency. As a second step, we examine the band-reverting tendency in more detail using the Markov-regime switching model and a three-regime threshold vector error correction model. As the results indicate, band-reverting tendencies are verifiable for all currencies, except for the Philippine peso. In particular, symmetrical band-reverting tendencies are observed whether exchange rates are beyond the upper boundary or below the lower boundary of the band. In the case of the Korean won and Taiwanese dollar, when these two currency exchange rates (measured against the yen deviate from a certain band, an adjustment process takes place in order to return toward the band.

Co-existence of multiple trade-off currencies shapes evolutionary outcomes.

Directory of Open Access Journals (Sweden)

Alan A Cohen

Full Text Available Evolutionary studies often assume that energy is the primary resource (i.e. "currency" at the heart of the survival-reproduction trade-off, despite recent evidence to the contrary. The evolutionary consequences of having a single trade-off currency versus multiple competing currencies are unknown. Using simulations, we modeled the evolution of either a single physiological currency between reproduction and survival, or of multiple such currencies. For a wide array of model specifications varying functional forms and strengths of the trade-offs, we show that the presence of multiple currencies (e.g. nutrients, time generally results in the evolution of higher lifetime reproductive success through partial circumvention of such trade-offs. Evolution of the underlying physiology is also more highly contingent with multiple currencies. These results challenge the paradigm of a single survival-reproduction trade-off as central to life history evolution, suggesting greater roles for physiological constraints and contingency, and implying potential selection for evolution of multiple trade-off currencies.

Virtual Currencies – monetary policy dilemmas and regulatory challenges

Directory of Open Access Journals (Sweden)

Daj Alexis

2018-01-01

Full Text Available Although the topic of virtual currencies is not completely new, the current technological developments and the extent of the globalisation process appear to have changed the scope of the research efforts needed to cover not only the advantages and opportunities, but also the disadvantages and threats that the expansion of virtual currencies can pose for monetary policy and the safety of the financial system. This paper comprises a brief presentation of the different types of virtual currencies and identifies some of the most significant implications of large-scale virtual currency adoption for monetary authorities and regulators, while providing an overview of the main trends in the evolution of virtual currencies. In the end, one conclusion is evident: whatever monetary policy or regulatory issues arise from the use of virtual currencies, their consequences are far from virtual.

2018-04-01

We present a simplistic model of the competition between different currencies. Each individual is free to choose the currency that minimizes his transaction costs, which arise whenever his exchanging relations have chosen a different currency. We show that competition between currencies does not necessarily converge to the emergence of a single currency. For large systems, we prove that two distinct communities using different currencies in the initial state will remain forever in this fractionalized state.

Effects of Synchronisation of Dynamics of Stock Indices and Currency Rates during Multifactor Analysis with the Use of Wavelet Technologies

Directory of Open Access Journals (Sweden)

Kravets Tetyana V.

2014-02-01

Full Text Available The article conducts analysis of behaviour of stock indices and currency rates before and after the crisis phenomena with the aim of detection of key features of the pre-crisis state, localisation and description of crisis effects by time and scale using methods of multifractal analysis and wavelet transformation. The article checks the method of allocation of intervals of self-similar behaviour of financial series in practice. For Dow Jones and Sand P 500 indices the article detects in the time interval of 2001 – 2013 fractality spans and also moments of time when behaviour of series was determined with the chaotic component. The article offers the measure of synchronous behaviour of stock indices and currency rates, value of which allows assessment of the degree of propagation of crisis phenomena and forecasting them. This measure is calculated for EUR/GBP, EUR/USD, FTSE 100, S and P 500, Dow Jones, DAX and CAC 40 series. The article observes a close connection between values of the introduced measure and volume of crisis phenomena, which took place in relevant period of time. It gives a characteristics of main economic crises for the period 2001 – 2003 with the aim of comparison of real events and specific features of dynamics of the measure of synchronisation as a precursor of crisis phenomena.

Advancing the design of a dynamic petro-dollar currency basket

International Nuclear Information System (INIS)

Elbeck, Matt

2010-01-01

This study offers Organization of Petroleum Exporting Countries (OPEC) member nations a crude oil pricing currency basket based on currency liquidity, in contrast with prior emphasis on OPEC trading patterns. Motivating the search for an alternative US dollar pricing of crude oil is the significant and inverse relationship (r=-0.82, p<0.01) between the US dollar major currencies index and crude oil price over the period January 1999-March 2009. A dynamically weighted petro-dollar currency basket is proposed based on the five currency claims (US dollar, Euro, British pound, Japanese yen and Swiss franc) and their varying proportions of foreign exchange reserves held by central banks. The major currencies US dollar index is compared against the proposed petro-dollar index to reveal an average US$8.1 billion annual gain in favor of the petro-dollar currency basket, offering OPEC members a revenue stream of diversified and highly liquid currencies to transition away from complete dependence on the US dollar crude oil pricing. The proposed petro-dollar crude oil pricing schema offers OPEC a crude oil price dynamically denominated in currencies reflecting the global use and importance of crude oil. This paper concludes with implementation issues facing a move toward the dynamically weighted petro-dollar crude oil pricing schema. (author)

Comparison of the two different standard flux-to-dose rate conversion factors

International Nuclear Information System (INIS)

Metghalchi, M.; Ashrafi, R.

1983-01-01

A very useful and simple way of obtaining the dose rate associated with neutron or photon fluxes is to multiply these fluxes by the appropriate flux-to-dose rate conversion factors. Two basic standard flux-to-dose rate conversion factors. are being used in all over the world, those recommended by the International Commission on Radiation Protection (ICRP) and the American National Standars (ANS). The purpose of this paper is to compare these two standard with each other. The comparison proved that the dose rate associated with a specific neutron flux, obtained by the ANS flux-to-dose rate conversion factors is usually higher than those calculated by the ICRP's conversion factors. Whereas in the case of the photon, in all energies, the difference between the dose rates obtained by these two standard flux-to-dose rate conversion factors are noticeable, and the ANS results are higher than the ICRP ones. So, it should be noted that for a specific neutron or photon flux the dose rate obtained by the ANS flux-to-dose rate conversion factors are more conservative than those obtained by the ICRP's. Therefore, in order to establish a more reasonable new standard flux-to-dose rate conversion factors, more work should be done. (author)

We study endogenous currency substitution in a decentralized trade environment. Sellers maximize profits from sales of imperfectly substitutable goods by posting prices in either one of two currencies. A unique symmetric equilibrium exists where goods are priced only in the local currency. This occurs if foreign trade is sporadic, there is sufficient but not excessive liquidity, and discounting is low. Excess or scarcity of liquidity, however, induces sellers to extract all surplus from buyer...

Customs unions, currency crises, and monetary policy coordination: The case of the Eurasian Economic Union

Directory of Open Access Journals (Sweden)

Evgeny Vinokurov

2017-09-01

Full Text Available After achieving substantial progress in establishing a common customs territory and regulations, customs unions face potential disruptions due to a lack of monetary policy coordination. These disruptions might appear in the form of currency shocks and the ensuing trade conflicts. We approach this issue by looking at the case of the Eurasian Economic Union (EAEU. The volatility of national currencies in 2014–2015 resulted in sizable shifts in competitiveness, culminating in a currency crisis in some member states. This raises the questions of how to gradually achieve a more coordinated monetary policy, what monetary policy options are available, and what would be their relative impact on macroeconomic stability. Using a set of modeling tools and econometric models, we review three monetary regimes, which represent moves from fully independent exchange rate policy through increased policy coordination to joint exchange rate setting.

Contamination rate of Ethiopian paper currency notes handled by various food handlers with Escherichia coli and antimicrobial susceptibility of the isolates was assessed. A total of 384 Ethiopian Birr (ETB) notes were randomly sampled from meat handlers at butchers, bread and the related food handlers at cafeteria, fruit and vegetables handlers at supermarket, and milk sellers both at open market and dairy station. Fifty control new currencies were also sampled from Commercial Bank of Ethiopia. Both surfaces of the currency were swabbed using wet sterile cotton. The swab was overnight incubated in buffered peptone water. A loop full was streaked on eosin methylene blue agar and followed by biochemical test on presumptive E. coli colonies. Randomly selected isolates were exposed to chloramphenicol (C-30 µg), neomycin (N-30 µg), oxytetracycline (OT-30 µg), polymyxin-B (PB-300 IU) and trimethoprim-sulfamethoxazole (SXT-1.25/23.75/µg) susceptibility using disc diffusion techniques. E. coli was not isolated from currency used as control. A total of 288 (75 %) currency notes were found carrying E. coli. E. coli prevalence was ranges from 67.2 % at open market milk sellers to 87.2 % at dairy station milk sellers; from 64.8 % on ETB 100 to 82.9 % on ETB 1. Differences were not observed in E. coli prevalence on currency notes from among almost all food handlers (P > 0.05). Susceptibility of tested isolates to each chloramphenicol, oxytetracycline and trimethoprim-sulfamethoxazole was 100 %, and to polymyxin-B was 97.3 %. High resistance (83.7 %) was observed to neomycin. The finding indicates, contaminated food can be a source of E. coli for further contamination of currency which again transfer through various foods ready for consumption.

Prediction of Currency Volume Issued in Taiwan Using a Hybrid Artificial Neural Network and Multiple Regression Approach

Directory of Open Access Journals (Sweden)

Yuehjen E. Shao

2013-01-01

Full Text Available Because the volume of currency issued by a country always affects its interest rate, price index, income levels, and many other important macroeconomic variables, the prediction of currency volume issued has attracted considerable attention in recent years. In contrast to the typical single-stage forecast model, this study proposes a hybrid forecasting approach to predict the volume of currency issued in Taiwan. The proposed hybrid models consist of artificial neural network (ANN and multiple regression (MR components. The MR component of the hybrid models is established for a selection of fewer explanatory variables, wherein the selected variables are of higher importance. The ANN component is then designed to generate forecasts based on those important explanatory variables. Subsequently, the model is used to analyze a real dataset of Taiwan's currency from 1996 to 2011 and twenty associated explanatory variables. The prediction results reveal that the proposed hybrid scheme exhibits superior forecasting performance for predicting the volume of currency issued in Taiwan.

Single European currency and Monetary Union. Macroeconomic implications for pharmaceutical spending.

Science.gov (United States)

Kanavos, P

1998-01-01

This article examines the potential implications of introducing a single currency among the Member States of the European Union for national pharmaceutical prices and spending. In doing so, it provides a brief account of the direct effects of introducing a single currency on pharmaceutical business. These are static in nature and include the elimination of exchange rate volatility and transaction costs, increased price transparency and limited potential for parallel trade. It subsequently analyses the potential medium and long term macroeconomic policy choices facing the Member States and their impact on pharmaceutical spending following the introduction of a single currency. These include policy directions in order to meet the Maastricht convergence criteria in the run-up to forming an Economic and Monetary Union (EMU) and the implications of EMU on national macroeconomic policy thereafter. This article argues that the necessity for tight fiscal policies across the EU and, in particular, in those Member States facing high budget deficits and overall debt levels, will continue to exert considerable downward pressure on pharmaceutical spending.

The Convergence Criteria and the SAARC Common Currency

Full Text Available These included cross-country standard deviations of call money rates, consumer price indices, real exchange rates, growth rates of foreign exchange reserves, growth rates of real volume of trade, growth rate of real relative volume of trade and the growth rates of real per capita GDP. None of the selected variables show signs for convergence of over the whole period of 1990s through 2000s. However, for the period of 2000s most of the economic indicators show signs of convergence. This suggests emerging signs for the prospects of common currency in SAARC region. The study, however, concludes that non-economic factors must also be considered seriously before making a serious move towards monetary union in the region.

Bosnian Draft of the law on the conversion of Swiss-francs loans: Critical review

Directory of Open Access Journals (Sweden)

Popović Igor

2016-01-01

Full Text Available Firstly, the author explains what motivated him to write this article, because Swiss-francs loans issue is very important for almost all Balkans states. After that, the essence of Swiss-francs loans is explained and what caused litigations relating to the nullity of these loans agreements. Courts are of the opinion that these agreements are legal and valid. They point out that currency clauses within these agreements are lawful and valid. Such courts' conclusion is a premise on which rests this article. The author emphasizes that subject of this article is not whether currency clauses regarding mentioned loans are lawful or not, but whether the Draft of the law on the conversion of Swiss-francs loans is constitutional and legitimate. The author explains the content of the mentioned Draft, especially the method of the intended conversion. Essence of the proposed conversion is as follows - conversion of Swiss-francs loans into the local currency (convertible mark at rates which had existed at the moment of the conclusion of an agreement. The author points to the vagueness of the Draft provisions and the possible problems that may arise in its application, if enacted. Next and main part of the article concerns the potential retroactive application of the Draft provisions. Draft covers all loans agreements, i.e. agreements which have ever been concluded, regardless of whether they are no longer in force. Thus, main effect of the Draft would be retroactive application of its provisions. Retroactivity undermines principle of legal certainty and to some extent principle of separation of powers, since courts have confirmed validity of the mentioned agreements. Draft, also, places all negative effects of rates exchange on creditors (banks, meaning that the question of proportionality could arise. Thus, the author argues that enactment of the Draft in proposed capacity would probably violate the principle of non-retroactive application of law and

Full Text Available Il presente articolo esamina i vantaggi relativi dei tassi di cambio fluttuanti nei confronti di un regime di tassi di cambio a parità rigidamente ancorate (hard peg, ponendo particolare enfasi sulle implicazioni per la domanda effettiva. In particolare, esso valuta se un deprezzamento della valuta abbia un effetto benefico sulla domanda aggregata e dunque sull’occupazione. Si sostiene che tale questione è centrale per il principio della domanda effettiva, e che l’idea che un deprezzamento valutario sia in grado di stabilizzare la domanda effettiva, equivale in larga misura a sostenere che la flessibilità (verso il basso dei salari nominali (e reali possa assicurare la piena occupazione. Coerentemente con ciò, viene analizzata la relazione tra la flessibilità verso il basso dei salari e la domanda effettiva, e viene valutata criticamente (dal punto di vista sia teorico sia empirico l’ipotesi che la flessibilità del tasso di cambio possa avere proprietà stabilizzanti quando si tenga conto di shock esogeni di varia natura. L’articolo si chiude con brevi deduzioni di teoria e di politica economiche.   This paper examines the relative advantages of floating exchange rates against a system of exchange rates for the same rigidly anchored (hard peg, with particular emphasis on the implications for effective demand. In particular, it will assess whether a currency depreciation has a beneficial effect on aggregate demand and hence employment. It is argued that this issue is central to the principle of effective demand, and that the idea that a currency depreciation is able to stabilize the effective demand, is equivalent to a large extent to support that flexibility (down in nominal wages (and real to ensure full employment. Consistent with this, we analyze the relationship between the downward flexibility of wages and effective demand, and is critically evaluated (in terms of both theoretical and empirical hypothesis that the flexibility

How do monetary institutions, such as currencies and central banks, interrelate to the construction of national communities? Using the national conflict between the Danish state and the Duchies of Schleswig-Holstein in the nineteenth century as an exemplary case, this article demonstrates how both...... banks and currencies were mobilized as political symbols to promote an agenda of regional nationalism. In the article I show how the local Schleswig-Holstein currency and the local Schleswig-Holsteinische Landsbank became symbolic antagonists to the Danish central bank and the official state......-sanctioned currency – which by Danish politicians were considers key elements in the attempt to consolidate the Danish nation-state.

Meiotic gene-conversion rate and tract length variation in the human genome.

Science.gov (United States)

Padhukasahasram, Badri; Rannala, Bruce

2013-02-27

Meiotic recombination occurs in the form of two different mechanisms called crossing-over and gene-conversion and both processes have an important role in shaping genetic variation in populations. Although variation in crossing-over rates has been studied extensively using sperm-typing experiments, pedigree studies and population genetic approaches, our knowledge of variation in gene-conversion parameters (ie, rates and mean tract lengths) remains far from complete. To explore variability in population gene-conversion rates and its relationship to crossing-over rate variation patterns, we have developed and validated using coalescent simulations a comprehensive Bayesian full-likelihood method that can jointly infer crossing-over and gene-conversion rates as well as tract lengths from population genomic data under general variable rate models with recombination hotspots. Here, we apply this new method to SNP data from multiple human populations and attempt to characterize for the first time the fine-scale variation in gene-conversion parameters along the human genome. We find that the estimated ratio of gene-conversion to crossing-over rates varies considerably across genomic regions as well as between populations. However, there is a great degree of uncertainty associated with such estimates. We also find substantial evidence for variation in the mean conversion tract length. The estimated tract lengths did not show any negative relationship with the local heterozygosity levels in our analysis.European Journal of Human Genetics advance online publication, 27 February 2013; doi:10.1038/ejhg.2013.30.

To date, the Croatian National Bank (HNB, as a regulator and formulator of monetary policy in Croatia has operated a policy of stable exchange rate, typically referenced to the formal currency of the European Union euro (EUR. From the date of introduction of the euro 01/01/1999 until 01/01/2016 the value of the currency pair HRK / EUR changed in value by only 4.25% (HNB. Although the value of the Croatian kuna is relatively stable, there are some fluctuations on an annual level (e.g. in ­­­the last few years because of the global crisis as well as  on periodic levels within a year. The aim of this paper is to show the movement of the value of the currency pair since the beginning of 2002 to the present day (the time curve, analyze the correctness, trends and periodicity (seasonal behavior, if any exist.The research will be done using the method of Time Series Analysis, assuming that the external (global economy and internal factors (economic policy remain similar or the same. According to the results, further assessment of price developments in the period followed will be made by using the obtained predicative models. In the event that the curve contains the component of periodicity, the observed patterns will be studied further.

Full Text Available In questo studio i motivi dietro le ampie fluttuazioni del tasso di cambio del dollaro a seguito del crollo del sistema di Bretton Woods, per la maggior parte non spiegata dalle teorie prevalenti del tasso di cambio, sono esplorate. L'autore indaga il tasso di cambio tra le due valute più scambiate, il dollaro e il marco tedesco, dal 1973 al 1988. Nella prima parte, il modello dei movimenti dei tassi di cambio quotidiani viene esaminato per dimostrare che una sequenza di rialzo o al ribasso interrotto da movimenti non direzionali è tipico della dinamica dei tassi di cambio nel breve periodo. Questo modello è sistematicamente sfruttata attraverso speculazione monetaria, in particolare attraverso l'uso di "analisi tecnica". Nella seconda parte, l'autore si concentra sul medio termine, sostenendo che le fluttuazioni possono essere spiegati come il risultato di interagire squilibri dei beni e mercati delle attività. Anche se valuta la speculazione è stata sistematicamente redditizio per la maggior parte delle valute, deve essere considerata destabilizzante in quanto la sequenza delle corse dei prezzi ha causato notevoli e persistenti deviazioni dei tassi di cambio dai loro valori di equilibrio (PIL.In this study the reasons behind the wide fluctuations of the dollar exchange rate following the breakdown of the Bretton Woods system, for the most part unexplained by the prevailing exchange rate theories, are explored.

In the first part, the pattern of the daily exchange rate movements is examined to show that a sequence of upward and downward trends interrupted by non-directional movements is typical of exchange rate dynamics in the short run. This pattern is systemically exploited through currency speculation, particularly through the use of “technical analysis”. In the second part, the author focuses on the

Lagrangian measurements of sulfur dioxide to sulfate conversion rates

Energy Technology Data Exchange (ETDEWEB)

Zak, B D

1981-12-01

On the basis of Project MISTT data and proposed homogenous gas phase oxidation mechanisms for sulfur dioxide, it has been suggested that the degree of mixing with background air, the chemical composition of the background air, and the intensity of the sunlight available are key factors determining the rate of sulfur dioxide to sulfate conversion. These hypotheses are examined in light of Lagrangian measrements of conversion rates in power plant plumes made during the Tennessee Plume Study and Project Da Vinci. It is found that the Lagrangian conversion rate measurements are consistent with these hypotheses. It has also been suggested that the concentration of ozone may serve as a workable surrogate for the concentrations of the free radicals involved in the homogeneous gas phase mechanism. The night-time Lagrangian data remind one that the gross difference in mean lifetime of ozone and free radicals can lead to situations in which the ozone concentration is not a good surrogate for the free radical concentrations.

Methods: when studying the role of state regulation of electronic money (crypto-currency, a dialectical method of scientific cognition was applied. Calculating and analytical methods of observing, measuring, analyzing and comparing indicators characterizing the state regulation of crypto-currencies in the Russian Federation, strengths and weaknesses, opportunities and threats to use and regulate crypto currency. Results: the authors conducted the analysis of the crypto-currency market, studied the experience and peculiarities of the state regulation of the crypto-currencies, examined and proposed strengths and weaknesses, opportunities and threats to use and regulate crypto-currencies. Conclusions and Relevance: in the process of studying the experience of regulating crypto currency in foreign countries, we found some similar features. First, each country seeks to create a favorable climate for the development of new technologies (detached and sees a high potential for using technology not only in the private sector, but also in the public sector. Secondly, the crypto-currency market is growing at a high pace, and the state, without adapting the tax code to the modern challenges of the digital economy, receives less revenue in the budget, since the crypto-currencies are out of legal jurisdiction. Thirdly, today there are more than 1 thousand different crypto-currencies, therefore, it is necessary to develop common standards for the regulation of crypto-currencies. 

Oil market structure, network effects and the choice of currency for oil invoicing

International Nuclear Information System (INIS)

Mileva, Elitza; Siegfried, Nikolaus

2012-01-01

Crude oil is a homogeneous good traded on specialised exchanges and quoted and invoiced predominantly in US dollars. Despite the strong case for the use of the US dollar as a vehicle currency in the oil trade, we provide an alternative view. We develop a simple network effects model to identify the conditions under which either a complete switch in the oil invoicing currency or parallel invoicing in different currencies is possible and economically sensible. We calibrate the model using low actual values for the transaction costs of using euro and/or US dollars, as well as a proxy for information costs, which decline with the increase in the use of the new currency. The results show that there will be a switch to parallel invoicing in both currencies when two conditions are met: first, oil exporters expect that a certain minimum number of other oil exporters will also start using the new currency; and second, the information costs associated with quoting oil contracts in two currencies are low. - Highlights: ► The US dollar as the dominant currency in the international trade of crude oil. ► We develop a model that treats currencies as network goods. ► The model predicts multiple equilibria with one or two vehicle currencies. ► Calibration shows that a switch to parallel invoicing in two currencies is possible.

Currency flaw severity. [Banknotes

Energy Technology Data Exchange (ETDEWEB)

Johnson, C.; Burnett, M.; Goodman, C.; Sherrod, R.; Schmoyer, R.; Harrison, C.; Uppuluri, R.

1986-01-01

A survey of currency flaw severity was carried out using 300 banknotes and 37 judges. Each judge assigned each note to one of five flaw severity categories. These categories correspond to severity grades of 1 to 5 with 1 equivalent to ''always accepted'' and 5 ''never accepted.'' An average flaw severity grade for each note was obtained by taking the mean of the severity grades assigned to that note by the 37 judges. Thus, each note has a single numerical real-number flaw grade between 1 and 5. Mathematical modeling of the currency flaw survey results is continuing with some very promising initial results. Our present model handles common excess ink and missing ink flaw types quite well. We plan to extend the model to ink level, mash, setoff and blanket impression flaw types.

Calculation of dose-rate conversion factors for external exposure to photons and electrons

International Nuclear Information System (INIS)

Kocher, D.C.

1978-01-01

Methods are presented for the calculation of dose-rate conversion factors for external exposure to photon and electron radiation from radioactive decay. A dose-rate conversion factor is defined as the dose-equivalent rate per unit radionuclide concentration. Exposure modes considered are immersion in contaminated air, immersion in contaminated water, and irradiation from a contaminated ground surface. For each radiation type and exposure mode, dose-rate conversion factors are derived for tissue-equivalent material at the body surface of an exposed individual. In addition, photon dose-rate conversion factors are estimated for 22 body organs. The calculations are based on the assumption that the exposure medium is infinite in extent and that the radionuclide concentration is uniform. The dose-rate conversion factors for immersion in contaminated air and water then follow from the requirement that all of the energy emitted in the radioactive decay is absorbed in the infinite medium. Dose-rate conversion factors for ground-surface exposure are calculated at a reference location above a smooth, infinite plane using the point-kernel integration method and known specific absorbed fractions for photons and electrons in air

The paper empirically investigates the determinants of currency invoicing in Dutch goods trade with OECD countries. To this end, a currency-share systems approach is employed, which is applied to quarterly panel data for 1987–1998. One of the key findings is that a country’s share of producer currency pricing falls if demand in the foreign export market falls. In addition, we find that the better developed the partner country’s banking sector and the larger its share in world trade, the lower...

Full Text Available To examine whether the recent price patterns and transaction costs of Bitcoin represent a general characteristic of decentralized virtual currencies, we analyze virtual currencies in online games that have been voluntarily managed by individuals since 1990s. We find that matured game currencies have price stability similar to that of small size equities or gold, and their transaction costs are sometimes lower than real currencies. Assuming that virtual currencies with a longer history can provide an estimate for Bitcoin's prospects, we project that Bitcoin will be less influenced by speculative trades and become a low cost alternative to real currencies.

To examine whether the recent price patterns and transaction costs of Bitcoin represent a general characteristic of decentralized virtual currencies, we analyze virtual currencies in online games that have been voluntarily managed by individuals since 1990s. We find that matured game currencies have price stability similar to that of small size equities or gold, and their transaction costs are sometimes lower than real currencies. Assuming that virtual currencies with a longer history can provide an estimate for Bitcoin’s prospects, we project that Bitcoin will be less influenced by speculative trades and become a low cost alternative to real currencies.

Full Text Available Introduction: Accumulated data obtained over the last 20 years on the microbial status and survival of pathogens on currency notes indicate that this could represent a potential cause of sporadic cases of food borne illness. Objectives: To identify the micro-organisms present on the Indian currency notes and the oral health risks due to microbial contamination of Indian currency notes circulating in Bengaluru city. Materials and Methods: A cross-sectional survey was conducted and the Indian currency notes of various denominations (Rs. 10, Rs. 20, Rs. 50, Rs. 100, Rs. 500, and Rs. 1000 were collected from fruit vendors, hawkers, vegetable vendors, bus conductors, railway ticket counters, hotel counters, and butchers. Sample size was determined to be 70 Indian currency notes. Convenience sampling technique was used. Microbiological analysis of the collected currency notes was done. Results: The contamination rate of collected currency notes from the butchers and hawkers were 80% and 60% respectively. Staphylococcus aureus was present on 15 currency notes (21.42% and was found to be higher in Rs. 10 than in other currency denominations. Streptococcus pyogenes was present on four currency notes (5.714% of Rs. 10. Conclusion: The Indian currency notes circulating in Bengaluru city were contaminated with pathogenic bacteria. The oral health risks due to microbial contamination of Indian currency notes are acute pharyngitis, peritonsillar or retropharyngeal abscess, mastoiditis, sinusitis, otitis media, mild cellulitis, angular cheilitis, some endodontic infections, osteomyelitis of the jaw, parotitis, and oral mucositis.

Invoice currency: Puzzling evidence and new questions from Brazil

Directory of Open Access Journals (Sweden)

Daniel Gersten Reiss

2015-05-01

Full Text Available This article for the first time uses Brazilian trade data to draw conclusions about the invoice currency choice — both in general and as it pertains to the Brazilian real (BRL. We find that the Brazil-Argentina policy of providing payment orders associated to an exchange transaction between their currencies has had a significant impact on the currency chosen for invoicing, establishing a link between the availability of financial instruments and the invoice currency choice. Moreover, the evidence does not confirm some previous international results. We identify that in Brazil there is no coincidence regarding the use of BRL for invoicing and its use for making payments. Yet we find that the main exports denominated in BRL are homogenous goods — sugar and tobacco — suggesting that some bargaining power might remain even if goods are traded in international markets. From the BRL-specific perspective, we categorically move away from the idea that the BRL is not used in Brazilian international trade. Although it is used at a limited absolute volume, an exceptional ninefold growth between 2007 and 2011 is observed. New intriguing questions about Brazilian currency usage can therefore be proposed.

2014-01-01

The universal adoption of fiat currencies and of the fractional reserve banking system coincided with access to and ability to utilize energy-dense fossil fuels leading to unprecedented rates of economic expansion. The depletion of economically recoverable fossil fuels though sets the stage for systemic crises as it is not adequately priced in the current market system. An energy-based system of exchange can be adopted in parallel to or in place of fiat currencies in order to facilitate a sustainable energy transition (SET) and mitigate the impacts of such crises. Energy-backed and energy-referenced currencies are discussed as two possible variants for their ability to realign the economic system to the thermodynamic limits of the physical world. The primary advantage of an energy-referenced currency over the current mechanisms for SET (like feed-in-tariffs or carbon taxes) is realized with the decoupling of the monetary and credit functions, especially when debt is tied to future energy availability. While energy-backed (credit) systems can be easier to adopt on a regional scale, the full transition to an energy-reference currency system requires significant reform of the financial and monetary system although it would not radically disrupt the current economic valuations given the high degree of correlation between value and embodied energy.

Full Text Available The author gives a brief excursus on the crypto-currency development, the theoretical understanding of a new kind of digital money. Today in the world there is no single interpretation of the crypto-currency, in some sources it is treated as a currency, others as a commodity or raw material. The appearance and use of Bitcoin (the main crypto-currency are considered by some authors as the evolution of the global financial system. The history of the crypto-currency origin, the distinctive features of cryptocurrency from the usual currency, the specifics of their use and relation to these governments are investigated and characterized by their legal status. There are real limitations in Australia, Germany, the Netherlands, New Zealand, Singapore, some US States and various offshore, they might constitute restrictive measures, as in Indonesia, China, Russia, and Ukraine. Many governments chose a wait – for example, the EU, UK, Switzerland, USA, Canada, Japan, countries of South-East Asia. The most significant signs of cryptocurrencies, such as decentralization, anonymity and lack of guarantees are marked. Two possible scenarios of crypto-currency development in Russia are proposed. The first scenario is prohibitive and the second one is regulatory. It is noted that the bitcoin should be banned, and should be studied, and then start to gradually adjust. Its benefits and disadvantages of the scenario use are highlighted. In addition, the author emphases the almost complete lack of a legal framework governing relations between clients of the new information network. As a result the study is focused not only on the necessity a detailed scientific study of crypto-currencies, but also on the need to develop institutional norms. Most of the developed countries adapt their legislation to regulate the new electronic money, which will allow slow to adapt innovation of the financial market - a crypto-currency to modern realities.

Through this paper, after making a detailed research into the current foreign currency policy of China and the experience of China Nuclear Power Engineering Corporate(CNPEC) during LA2 project, the author evaluates the current ability of foreign currency settlement ability and defines the applicable process in CNPEC, in order to meet the future needs of CNPEC to make foreign currency payment for the multiple nuclear power projects. To ensure the foreign payment can be settled successfully, CNPEC should pay more attention to the import duty, foreign currency loan, clearing method, remittance after verification, as well as the financial risk management of foreign currency loan. On the premise that CNPEC can also get entitlement of import duty and value added tax preference, the author makes the point about how to enhance the capacity of foreign currency payment of CNPEC.

Financial liberalization, currency substitution and savings in Nigeria: Evidence from cointegration and error correction modeling

Directory of Open Access Journals (Sweden)

M Aziakpono

2004-04-01

Full Text Available The study set out to test the McKinnon-Shaw proposition that financial liberalization will significantly increase savings mobilization. The results partly supported the financial liberalization proposition. Variables that capture the effects of currency substitution such as the interest rate differential, a proxy for underground economy, the inflation differential (as a measure of macroeconomic instability and a dummy for political instability were significant in their adverse impacts on the saving mobilization process in Nigeria. We, therefore, advocate for an active monetary policy that will help manage the delicate balance between domestic and foreign interest rates. This should be combined with macroeconomic policies that create a stable economic environment along with appropriate financial and exchange rate policies, in order to discourage economic agents from preferring foreign denominated assets to those held in the domestic currency.

Calculation of neutron and gamma-ray flux-to-dose-rate conversion factors

International Nuclear Information System (INIS)

Kwon, S.G.; Lee, S.Y.; Yook, C.C.

1981-01-01

This paper presents flux-to-dose-rate conversion factors for neutrons and gamma rays based on the American National Standard Institute (ANSI) N666. These data are used to calculate the dose rate distribution of neutron and gamma ray in radiation fields. Neutron flux-to-dose-rate conversion factors for energies from 2.5 x 10 -8 to 20 MeV are presented; the corresponding energy range for gamma rays is 0.01 to 15 MeV. Flux-to-dose-rate conversion factors were calculated, under the assumption that radiation energy distribution has nonlinearity in the phantom, have different meaning from those values obtained by monoenergetic radiation. Especially, these values were determined with the cross section library. The flux-to-dose-rate conversion factors obtained in this work were in a good agreement to the values presented by ANSI. Those data will be useful for the radiation shielding analysis and the radiation dosimetry in the case of continuous energy distributions. (author)

The role of nuclear power generation in aspects of the foreign currency outflow

International Nuclear Information System (INIS)

Kim, Seung Su; Lee, Man Ki

2005-01-01

Korea has little domestic energy resources and so imported almost all of the primary energy consumed from the foreign countries, with the foreign energy dependency being about more than 97% in recent years. In the meantime, the import amount of energy together with the rapid economic growth has increased continuously during the past 30 years to be 49.6 billion dollar in 2004 while the Current Account Balance was 27.6 billion dollar in the same year. Especially, the growth rate of electric consumption greatly surpassed ones in GDP and primary energy over the past 20 years. Nuclear power generation has played an important role in Korean society by supporting the industrial development as well as stabilizing downward the electricity price. The steady progress in the localization of nuclear construction has decreased the amount of foreign currency outflow by the nuclear power plant construction. In addition, nuclear fuel cost is the most competitive among those of the other fossil fuel power sources, so that this situation resulted in the large decrease of foreign currency outflow in power sector. In this thesis, we focused on the savings effect in foreign currency outflow by nuclear power generation using the scenario method. We tried to evaluate what amount of foreign currency has been saved by the introduction of nuclear power plant instead of the other fossil fuel power plants

On the equivalence between the minimum entropy generation rate and the maximum conversion rate for a reactive system

Bispo, Heleno; Silva, Nilton; Brito, Romildo; Manzi, João

Highlights: • Minimum entropy generation (MEG) principle improved the reaction performance. • MEG rate and the maximum conversion equivalence have been analyzed. • Temperature and residence time are used to the domain establishment of MEG. • Satisfying the temperature and residence time relationship results a optimal performance. - Abstract: The analysis of the equivalence between the minimum entropy generation (MEG) rate and the maximum conversion rate for a reactive system is the main purpose of this paper. While being used as a strategy of optimization, the minimum entropy production was applied to the production of propylene glycol in a Continuous Stirred-Tank Reactor (CSTR) with a view to determining the best operating conditions, and under such conditions, a high conversion rate was found. The effects of the key variables and restrictions on the validity domain of MEG were investigated, which raises issues that are included within a broad discussion. The results from simulations indicate that from the chemical reaction standpoint a maximum conversion rate can be considered as equivalent to MEG. Such a result can be clearly explained by examining the classical Maxwell–Boltzmann distribution, where the molecules of the reactive system under the condition of the MEG rate present a distribution of energy with reduced dispersion resulting in a better quality of collision between molecules with a higher conversion rate

Effectiveness of high interest rate policy on exchange rates: A reexamination of the Asian financial crisis

Directory of Open Access Journals (Sweden)

Chin Diew Lai

2006-09-01

Full Text Available One of the most controversial issues in the aftermath of the Asian financial crisis has been the appropriate response of monetary policy to a sharp decline in the value of some currencies. In this paper, we empirically examine the effects on Asian exchange rates of sharply higher interest rates during the Asian financial crisis. Taking account of the currency contagion effect, our results indicate that sharply higher interest rates helped to support the exchange rates of South Korea, the Philippines, and Thailand. For Malaysia, no significant causal relation is found from the rate of interest to exchange rates, as the authorities in Malaysia did not actively adopt a high interest rate policy to defend the currency.

FINANCIAL AND LEGAL CONSIDERATIONS OF THE FOREIGN EXCHANGE RATES ON BANK EXTERNAL TRADING OPERATIONS

Full Text Available The term "currency" has different meanings but is usually defined as any means of payment that is not in local currency units. The ratio between the foreign currency and local currency units results into exchange rate. When arranging payment transactions abroad, local entities - natural and legal persons must exchange their national currency in advance for the currency of the country in which they are due or in another currency commonly accepted as an international payment. Under this regime, the national currency is quoted in relation to another currency, that is exchange rate.

Virtual World Currency Value Fluctuation Prediction System Based on User Sentiment Analysis.

Full Text Available In this paper, we present a method for predicting the value of virtual currencies used in virtual gaming environments that support multiple users, such as massively multiplayer online role-playing games (MMORPGs. Predicting virtual currency values in a virtual gaming environment has rarely been explored; it is difficult to apply real-world methods for predicting fluctuating currency values or shares to the virtual gaming world on account of differences in domains between the two worlds. To address this issue, we herein predict virtual currency value fluctuations by collecting user opinion data from a virtual community and analyzing user sentiments or emotions from the opinion data. The proposed method is straightforward and applicable to predicting virtual currencies as well as to gaming environments, including MMORPGs. We test the proposed method using large-scale MMORPGs and demonstrate that virtual currencies can be effectively and efficiently predicted with it.

2010-12-01

Although there are extensive researches on the behavior of the world currency network, the complexity of the Asian regional currency system is not well understood regardless of its importance. Using daily exchange rates this paper examines exchange rate co-movements in the region before and after the China exchange rate reform. It was found that the correlation between Asian currencies and the US Dollar, the previous regional key currency has become weaker and intra-Asia interactions have increased. Cross sample entropy and cross entropy approaches are also applied to examine the synchrony behavior among the Asian currencies. The study also shows that the Asian exchange rate markets featured are neither stochastic nor efficient. These findings may shed some light on the in-depth understanding of collective behaviors in a regional currency network; they will also lay a theoretical foundation for further policy formulation in Asian currency integration.

Estimates of external dose-rate conversion factors and internal dose conversion factors for selected radionuclides released from fusion facilities

This report provides a tabulation of both external dose-rate conversion factors and internal dose conversion factors using radioactive decay data in the updated Evaluated Nuclear Structure Data File (ENSDF) for selected 26 radionuclides and all their daughter radionuclides of potential importance in safety assessments of fusion facilities. The external dose-rate conversion factors for 21 target organs are tabulated for three exposure modes that are immersion in contaminated air, irradiation at a height of 1 m above a contaminated ground surface and immersion contaminated water. For internal exposure, committed dose equivalents, based on the methodology of ICRP Publication 30, in the same target organs per intake of unit activity are given for the inhalation and ingestion exposure pathways. The data presented here is intended to be generally used for safety assessments of fusion reactors. Comparisons of external effective dose-rate conversion factors and committed effective dose equivalents are made with the previous data from the independent data bases to provide quality assurance on our calculated results. There is generally good agreement among data from the independent data bases. The differences in the values of both effective dose-rate and dose conversion factors appeared are primarily due to differences in calculational methodology, the use of different radioactive decay data, and compilation errors.

This paper offers two ways to decentralize the constrained-efficient allocation of the Lagos–Wright (2005) pure currency economy. The first way has divisible money, take-it-or-leave-it offers by buyers, and a transfer scheme financed by money creation. If agents are sufficiently patient, the first best is achieved for finite money growth rates. If agents are impatient, the equilibrium allocation approaches the constrained-efficient allocation asymptotically as the money growth rate tends to i...

A two-stage variable sample-rate conversion (SRC) system has been pro posed as part of a digital signal-processing system in a digital com munication radio receiver that utilizes a variety of data rates. The proposed system would be used as an interface between (1) an analog- todigital converter used in the front end of the receiver to sample an intermediatefrequency signal at a fixed input rate and (2) digita lly implemented tracking loops in subsequent stages that operate at v arious sample rates that are generally lower than the input sample r ate. This Two-Stage System would be capable of converting from an input sample rate to a desired lower output sample rate that could be var iable and not necessarily a rational fraction of the input rate.

2014-01-01

Full Text Available The article deals with the problem caused by the crisis of the Jamaican currency system, namely, with the search for new forms of money that can replace dollars in international transactions. Alternative currency as the best global option has been searched both by national governments and international organisations, as well as the world’s leading scientists. All current studies, and our research, are based on historical definition of the nature, forms and other aspects of money. The theoretical principles that have been studied helped confirm our hypotheses about the existence of absolutely new forms of money, including electronic. In this study, we proved that there are all necessary prerequisites for existence of electronic money as a new global currency. The key risks and possible directions of their neutralising were analysed. This allowed reviewing the hypothesis of introduction of fiduciary electronic money, studying historical facts of their existence and substantiating their implementation

The estimated 3.7 million Americans with low vision experience a uniquely difficult task in identifying the denominations of U.S. banknotes because the notes are remarkably uniform in size, color, and general design. The National Research Council's Committee on Currency Features Usable by the Visually Impaired assessed features that could be used by people who are visually disabled to distinguish currency from other documents and to denominate and authenticate banknotes using available technology. Variation of length and height, introduction of large numerals on a uniform, high-contrast background, use of different colors for each of the six denominations printed, and the introduction of overt denomination codes that could lead to development of effective, low-cost devices for examining banknotes were all deemed features available now. Issues affecting performance, including the science of visual and tactile perception, were addressed for these features, as well as for those features requiring additional research and development. In this group the committee included durable tactile features such as those printed with transparent ink, and the production of currency with holes to indicate denomination. Among long-range approaches considered were the development of technologically advanced devices and smart money.

Derivation of pulse height to exposure rate conversion functions for aerial radiological surveys

International Nuclear Information System (INIS)

Artuso, J.F.

1985-01-01

A method is described for deriving conversion functions that can be used to convert pulse height spectra taken at altitude to the exposure rate at the 1-m level. An integral equation is set up which involves the integration of a calculated pulse height spectrum multiplied by an unknown conversion function and then set equal to the exposure rate at ground level. This equation is then solved for the conversion function by assuming as a solution a three-term polynomial. Conversion functions have been derived for various source distributions, including surface, uniform, and exponentially distributed sources. These conversion functions are independent of source energy, which means that a conversion can be made without any knowledge of the isotopic content of the source. In the case of a uniform distribution, these conversion functions provide conversions that agree to within 10% with ground truth measurements

2012-12-01

Full Text Available In recent years, most countries in Central and Eastern Europe, Member States of the EU, that we selected for the analysis (Bulgaria, Czech Republic, Estonia, Hungary, Latvia, Lithuania, Poland, Romania have recorded a significant expansion of lending in foreign currency, which was one of the major factors of the accelerated growth of loans to economy. Such developments have led to an increase of indebtedness in foreign currency of the non-financial private sector, especially of the households and of the accumulation of major macroeconomics and financial imbalances. The issue of lending in foreign currency, the determinants of increasing the share of loans in foreign currency and the risks generated at the level of financial stability are the subject of numerous studies, including: Basso, Calvo-Gonzales and Jurgilas (2007; Rosenberg and Tirpak (2008; Csajbók-Andras et al. (2010; Zettelmeyer, Nagy and Jeffrey (2010. Another significant issue addressed in the specialized literature regarding foreign currency loans refers to the role of monetary policy in limiting growth of these loans. Thus, in addition to those noted studies we remark other studies, such as: Kiss et al. (2006; Sirtaine and Skamnelos (2007; Hilbers et al. (2006; Brzoza-Brzezina et al. (2010. Our paper complements the specialized literature on the approached subject, in particular, by highlighting and discussing current issues of high interest for policymakers, both at national and European level regarding lending in foreign currency. The extremely negative implications of lending in foreign currency on financial stability in most countries under review, outlined clearly in the context of the current crisis, determined the focus of the policymakers concern, both at European and national level, regarding the issue of foreign currency loans, which became one of the most discussed issues on the agenda of the monetary-financial authorities.

Full Text Available This paper is part of a larger research that aims to analyze the deviation between the Real Exchange Rate and the Equilibrium Exchange Rate in Romania (EUR/RON currency and to come up with conclusions regarding this deviation and with solutions to minimize it, if the case. Because this is the most important discussion after having the empirical results: what do emergent markets like Romania need to do to keep up with the EU trend? Which are the concessions they have to make in order to maintain a sustainable growth? Do these concessions include breaking the present equilibrium for a future BETTER? Starting with the most well-known methods to calculate the Equilibrium Exchange Rate, this article`s purpose is to create an accurate overview on the UIP model in Romania (the interest rate differential, to verify, using the latest data if the economic environment has brought any changes on the results of this model in the latest years. Is the UIP model a trustworthy equation to establish the Equilibrium Exchange Rate? In order to verify if the UIP model was more reliable in returning a value for the Equilibrium Exchange rate in the latest years on the Romanian market, this paper presents an empirical study containing recent compiled data from the last 10 years, analyzing the 2005 – 2014 period. The NEW in this article is that the used data is very fresh, currently, most probably the only study that verifies the UIP model in Romania for this specific period of time. Why is it useful? Why is it important? Because it doesn`t only bring a confirmation of weather the UIP works for Romania or not but comes up with hints and conclusions regarding the current economic situation of Romania. We can see what has been changed in the local market in the last ten years in terms of monetary policy and what has this change brought with it – if the results are those expected or not and also, what would be the direction for the next years – to most suitable

Results of a massive experiment on virtual currency endowments and money demand.

Directory of Open Access Journals (Sweden)

Nenad Živić

Full Text Available We use a 575,000-subject, 28-day experiment to investigate monetary policy in a virtual setting. The experiment tests the effect of virtual currency endowments on player retention and virtual currency demand. An increase in endowments of a virtual currency should lower the demand for the currency in the short run. However, in the long run, we would expect money demand to rise in response to inflation in the virtual world. We test for this behavior in a virtual field experiment in the football management game Top11. 575,000 players were selected at random and allocated to different "shards" or versions of the world. The shards differed only in terms of the initial money endowment offered to new players. Money demand was observed for 28 days as players used real money to purchase additional virtual currency. The results indicate that player money purchases were significantly higher in the shards where higher endowments were given. This suggests that a positive change in the money supply in a virtual context leads to inflation and increased money demand, and does so much more quickly than in real-world economies. Differences between virtual and real currency behavior will become more interesting as virtual currency becomes a bigger part of the real economy.

A crucial question centering many recent debates in the international macroeconomics is under which currency the price is sticky. This paper provides a microfoundation to study the firm¡¦s choice of price setting currency in the sticky price model. I first prove that the risk preference is a secondary consideration in the choice of the price setting currency. This result questions the claim that the currency forward market can change the currency choice of risk averse firms. Then I extend the...

Full Text Available Bank Indonesia Regulation No.18/18/PBI/2016 concerning foreign exchange transactions against rupiah between banks and domestic parties, indicates that the importance of hedging for business actors in Indonesia. Based on the data of the rupiah exchange rate movement against the dollar from January 2006 to December 2016 shows that the fluctuation of the rupiah against the US dollar tends to weaken, although at some point the observation shows the strengthening of the rupiah against the US dollar. The purpose of this research is to assess impact of Forward, Forward Option and No Hedging Strategy for managing currency exposure between IDR to USD. Using data from January 2006–December 2016 taken from website of Bank Indonesia and Federal Reserve. Total 396 simulations,consists of 132 using Forward simulations, 132 using Forward Option simulations and 132 using No Hedging simulations. Findings from this research show that Forward Option was has no positive contribution in managing currency exposure, No Hedging Strategy has 36,36 percent positive contribution and forward contract has 72,73 percent positive contribution in managing currency exposure. Its means Forward Contract was better than Forward Option and No Hedging Strategies in managing currency exposure.

Full Text Available In this paper we provide a brief discourse on the theory of optimum currency areas to serve as a basis for constructive criticism of the conceptual framework of the eurozone. With particular reference to the Greek economic crisis, we argue that the very architecture of the EU experiment involving the single currency was inherently flawed from the outset in so far as political pressures to speed up the process towards a politically unified Europe has resulted in what is perceived as the worst economic impasse in the history of modern capitalism.

RITUAL USE OF CURRENCY IN LAIMBWE HISTORY, CAMEROON

Directory of Open Access Journals (Sweden)

Henry Kam Kah

2018-02-01

Full Text Available The advent of Europeans in Cameroon in the 15th century and the introduction of a western currency as a standard of exchange and a measurement of value to replace other indigenous currencies had an impact on initiation into regulatory and entertainment societies in Cameroonian communities including the Laimbwe of the North West Region. Male and female institutions eventually began using these currencies during initiation rites. These included nwerong, ngiri, ngumba, takembeng, ndofoumgbui, kwifoyn (also kwifo’o, kwifeu, kuiifuai kefa’a, tschong, libah and ikuum in the grasslands and Liengu, male, ahon, muankum, nganya, monekim, ekpe and obasinjom in the forest region of Cameroon. Prior to the introduction of standard money, some local currencies like cowrie shells were used together with the provision of material things like goats, pigs, fowls and bush meat. Money is effectively a measure of value, status and a store of wealth within the Laimbwe traditional milieu. This paper examines how and why the introduction of money in initiation and other ritual activities led to the emergence of new social classes and the re-enforcement of the socio-political order of the Laimbwe people. The study essentially relies on discussions with members of societies, observation and written material.

What shakes the FX tree? Understanding currency dominance, dependence, and dynamics (Keynote Address)

Science.gov (United States)

Johnson, Neil F.; McDonald, Mark; Suleman, Omer; Williams, Stacy; Howison, Sam

2005-05-01

There is intense interest in understanding the stochastic and dynamical properties of the global Foreign Exchange (FX) market, whose daily transactions exceed one trillion US dollars. This is a formidable task since the FX market is characterized by a web of fluctuating exchange rates, with subtle inter-dependencies which may change in time. In practice, traders talk of particular currencies being 'in play' during a particular period of time -- yet there is no established machinery for detecting such important information. Here we apply the construction of Minimum Spanning Trees (MSTs) to the FX market, and show that the MST can capture important features of the global FX dynamics. Moreover, we show that the MST can help identify momentarily dominant and dependent currencies.

Costs of Adopting a Common European Currency. Analysis in Terms of the Optimum Currency Areas Theory

Directory of Open Access Journals (Sweden)

Aura Gabriela SOCOL

2011-02-01

Full Text Available This analysis presents a theoretical approach of the possible costs related to a national economy which desires to be part of a monetary union. The analysis is made in terms of the classical optimum currency areas theory, which represents the basis of the monetary union process. The objective of this theory was to make a monetary union possible. This theory shows that the countries can obtain net benefits as a result of having a common currency, thus being able to avoid the possible adjustment problems. As a matter of fact, its great merit is that it identified certain properties of the countries being part of a monetary union, these properties representing real alternative tools for losing the independence of the monetary policy

Defining features of interaction policy among national economies and IFI in the monetary sphere, considering countries’ socio-economic parameters of development, will allow monetary authorities to achieve the optimum level of development of its economy. Methodology. Theoretical base of the study are the provisions of general scientific theory of knowledge studied phenomena and processes, in particular: methods of induction and deduction (in determining classification criteria of IFIs impact on national currency system, analysis and synthesis (in determining the features and priorities of national currency system, comparisons, associations and analogies (the justification of characteristics of advantages and disadvantages of IFI. The information base for scientific research is scientific papers and publications of domestic and foreign scientists-economists, materials of scientific-practical conferences, legislative and normative documents, the IMF, World Bank and Asian Infrastructure Investment Bank materials. Results. Theoretical approaches to the definition of the national currency system and international financial organizations, including its classification, are proposed. It is proved that the IMF makes active impact on national currency policy formation through regulation and supervision, while the World Bank and AIIB are related in a passive way. The IFI regulation trends are to implement floating exchange regime, liberal currency transactions, cancel currency restrictions in member countries. Although it refers to all countries, some of them with large population, trading, underdeveloped institutions of democracy could avoid some IFI pressure. Practical implications. The study accents attention on the specifics of the IFI activity in terms of

Keurentjes, José H M; Briët, Justine M; de Bock, Geertruida H; Mourits, Marian J E

2018-02-01

A multicenter, retrospective, cohort study was conducted in the Netherlands. The aim was to evaluate whether surgical volume of laparoscopic hysterectomies (LHs) performed by proven skilled gynecologists had an impact on the conversion rate from laparoscopy to laparotomy. In 14 hospitals, all LHs performed by 19 proven skilled gynecologists between 2007 and 2010 were included in the analysis. Surgical volume, conversion rate and type of conversion (reactive or strategic) were retrospectively assessed. To estimate the impact of surgical volume on the conversion rate, logistic regressions were performed. These regressions were adjusted for patient's age, Body Mass Index (BMI), ASA classification, previous abdominal surgery and the indication (malignant versus benign) for the LH. During the study period, 19 proven skilled gynecologists performed a total of 1051 LHs. Forty percent of the gynecologists performed over 20 LHs per year (median 17.3, range 5.4-49.5). Conversion to laparotomy occurred in 5.0% of all LHs (53 of 1051); 38 (3.6%) were strategic and 15 (1.4%) were reactive conversions. Performing over 20 LHs per year was significantly associated with a lower overall conversion rate (OR adjusted 0.43, 95% CI 0.24-0.77), a lower strategic conversion rate (OR adjusted 0.32, 95% CI 0.16-0.65), but not with a lower reactive conversion rate (OR adjusted 0.96, 95% CI 0.33-2.79). A higher annual surgical volume of LHs by proven skilled gynecologists is inversely related to the conversion rate to laparotomy, and results in a lower strategic conversion rate.

2002-04-01

One of the goals of the 1996 series design was to integrate highly recognizable features that enable the general public to more easily distinguish counterfeit from genuine notes, thereby reducing the chance of counterfeit notes being passed. The purpose of this study is to evaluate how knowledgeable the public is concerning the new currency, to identify the channels through which the public learns about new currency design, and to assess the usefulness of the new currency's authentication features. Also, the study will serve as a baseline measurement for future design studies and in comparative analysis with other countries. The results of the qualitative research will be described in the following sections of this paper. The quantitative research is scheduled to begin in February 2002, at the same time as the Netherlands' opinion poll of the Euro and NLG-notes in an effort to compare results.

Optimization of mass flow rate in RGTT200K coolant purification for Carbon Monoxide conversion process

International Nuclear Information System (INIS)

Sumijanto; Sriyono

2016-01-01

Carbon monoxide is a species that is difficult to be separated from the reactor coolant helium because it has a relatively small molecular size. So it needs a process of conversion from carbon monoxide to carbondioxide. The rate of conversion of carbon monoxide in the purification system is influenced by several parameters including concentration, temperature and mass flow rate. In this research, optimization of the mass flow rate in coolant purification of RGTT200K for carbon monoxide conversion process was done. Optimization is carried out by using software Super Pro Designer. The rate of reduction of reactant species, the growth rate between the species and the species products in the conversion reactions equilibrium were analyzed to derive the mass flow rate optimization of purification for carbon monoxide conversion process. The purpose of this study is to find the mass flow rate of purification for the preparation of the basic design of the RGTT200K coolant helium purification system. The analysis showed that the helium mass flow rate of 0.6 kg/second resulted in an un optimal conversion process. The optimal conversion process was reached at a mass flow rate of 1.2 kg/second. A flow rate of 3.6 kg/second – 12 kg/second resulted in an ineffective process. For supporting the basic design of the RGTT200K helium purification system, the mass flow rate for carbon monoxide conversion process is suggested to be 1.2 kg/second. (author)

Keskin, Mustafa; Deviren, Bayram; Kocakaplan, Yusuf

2011-02-01

We studied the topology of correlation networks among 34 major currencies using the concept of a minimal spanning tree and hierarchical tree for the full years of 2007-2008 when major economic turbulence occurred. We used the USD (US Dollar) and the TL (Turkish Lira) as numeraires in which the USD was the major currency and the TL was the minor currency. We derived a hierarchical organization and constructed minimal spanning trees (MSTs) and hierarchical trees (HTs) for the full years of 2007, 2008 and for the 2007-2008 period. We performed a technique to associate a value of reliability to the links of MSTs and HTs by using bootstrap replicas of data. We also used the average linkage cluster analysis for obtaining the hierarchical trees in the case of the TL as the numeraire. These trees are useful tools for understanding and detecting the global structure, taxonomy and hierarchy in financial data. We illustrated how the minimal spanning trees and their related hierarchical trees developed over a period of time. From these trees we identified different clusters of currencies according to their proximity and economic ties. The clustered structure of the currencies and the key currency in each cluster were obtained and we found that the clusters matched nicely with the geographical regions of corresponding countries in the world such as Asia or Europe. As expected the key currencies were generally those showing major economic activity.

Can yen be the currency for international settlement and foreign reserves; En no kokusaika (kessai junbi tsuka toshite no en no kanosei)

Hiraki, S. [Niigata University, Niigata (Japan). Faculty of Engineering

1995-11-20

Taking as the first on the list the fall in the status of the U.S. dollar as seen in aiding the Mexican currency liquidity crisis, this paper traces the course of weakening of the U.S. dollar and changes in foreign exchange rates, and explains the internationalization and expectation on the yen as a supplementary key currency. Since the American trade balance had turned into deficit in 1970, the value of the U.S. dollar has declined against that of the Japanese yen and German mark. It is clear from change in the IMF assignment amount that the two latter currencies are taking the role for international settlement and as reserve currencies. The import contracts denominated in yen in Asia during 1991 have stayed as low as at 21.6% based on the prediction of the appreciating trend of yen, while those for the export contracts have exceeded 50%. Although the amount of yen reserved in every country as the reserve currency is still small, it is anticipated that yen will be playing more important role as one of the key currencies in the future. However, it is also a fact that there are several problems for yen to be capable of being used for the international settlement and as the reserve currency. 1 fig., 4 tabs.

Currency risk and prices of oil and petroleum products: a simulation with a quantitative model

International Nuclear Information System (INIS)

Aniasi, L.; Ottavi, D.; Rubino, E.; Saracino, A.

1992-01-01

This paper analyzes the relationship between the exchange rates of the US Dollar against the four major European currencies and the prices of oil and its main products in those countries. In fact, the sensitivity of the prices to the exchange rate movements is of fundamental importance for the refining and distribution industries of importing countries. The result of the analysis shows that in neither free market conditions, as those present in Great Britain, France and Germany, nor in regulated markets, i.e. the italian one, do the variations of petroleum product prices fully absorb the variation of the exchange rates. In order to assess the above relationship, we first tested the order of co-integration of the time series of exchange rates of EMS currencies with those of international prices of oil and its derivative products; then we used a transfer-function model to reproduce the quantitative relationships between those variables. Using these results, we then reproduced domestic price functions with partial adjustment mechanisms. Finally, we used the above model to run a simulation of the deviation from the steady-state pattern caused by exchange-rate exogenous shocks. 21 refs., 5 figs., 3 tabs

Constraints, Trade-offs and the Currency of Fitness.

Science.gov (United States)

Acerenza, Luis

2016-03-01

Understanding evolutionary trajectories remains a difficult task. This is because natural evolutionary processes are simultaneously affected by various types of constraints acting at the different levels of biological organization. Of particular importance are constraints where correlated changes occur in opposite directions, called trade-offs. Here we review and classify the main evolutionary constraints and trade-offs, operating at all levels of trait hierarchy. Special attention is given to life history trade-offs and the conflict between the survival and reproduction components of fitness. Cellular mechanisms underlying fitness trade-offs are described. At the metabolic level, a linear trade-off between growth and flux variability was found, employing bacterial genome-scale metabolic reconstructions. Its analysis indicates that flux variability can be considered as the currency of fitness. This currency is used for fitness transfer between fitness components during adaptations. Finally, a discussion is made regarding the constraints which limit the increase in the amount of fitness currency during evolution, suggesting that occupancy constraints are probably the main restrictions.

The paper considers three methods for eliminating the zero lower bound on nominal interest rates and thus for restoring symmetry to domain over which the central bank can vary its policy rate. They are: (1) abolishing currency (which would also be a useful crime-fighting measure); (2) paying negative interest on currency by taxing currency; and (3) decoupling the numéraire from the currency/medium of exchange/means of payment and introducing an exchange rate between the numéraire and the curr...

CORRECTION OF FORECASTS OF INTERRELATED CURRENCY PAIRS IN TERMS OF SYSTEMS OF BALANCE RATIOS

Directory of Open Access Journals (Sweden)

Gertsekovich D. A.

2015-03-01

Full Text Available In this paper the problem of exchange rates forecast is logically considered a traditionally as a task of forecast on the base of «stand-alone» equations of autoregression for each currency pair and b as a result of forecast correction of autoregression equations system on the base of boundary conditions of balance ratios systems. As a criterion for quality of forecast constructed with empirical models we take the sum of deficiency quadrates of forecasts estimated for deductive currency pairs. Practical approval confirmed that deductive models meet common requirements, provide accepted precision, show resistance to initial data and are free from series of deficiency of one index. However, extreme forecast errors tell that practical application of the approach offered needs further improvement.

Effects of Exchange Rate Instability on Imports and Exports of Pakistan

2014-04-01

Full Text Available The instability in exchange rate (appreciation and depreciation in home currency is an important factor indetermination of trade balance of a country. Fluctuating exchange rates impacts the decision making of investors and traders, it shatters their confidence which ultimately leads to the slowness of trade process. In this research paper the effect of exchange rate instability is measured on imports and exports of Pakistan. For this purpose Regression analysis is used and it is calculated that if instability is created due to depreciation in home currency (Pak rupee then it has positive impact on Pakistan‘s exports, while it has absolutely no effect on imports of Pakistan. Since Pak rupee has very limited appreciation during last 20 years so appreciation effect of home currency can not be calculated on Imports and exports of Pakistan. In theoretical prospective the devaluation of home currency should decrease the volume of imports, because it will cost more for Pakistan to import goods from other countries. But our empirical findings show that, this is not the case between exchange rate and imports of Pakistan. The imports of Pakistan grew even in large figure as the home currency depreciated against other currencies. So this shows that depreciation of home currency do not effect the imports in of Pakistan. Our findings through regression analysis show that by decrease in value of home currency imports of Pakistan increase. So depreciation in home currency has no effect on imports volume.

Parameter motivated mutual correlation analysis: Application to the study of currency exchange rates based on intermittency parameter and Hurst exponent

Science.gov (United States)

Cristescu, Constantin P.; Stan, Cristina; Scarlat, Eugen I.; Minea, Teofil; Cristescu, Cristina M.

2012-04-01

We present a novel method for the parameter oriented analysis of mutual correlation between independent time series or between equivalent structures such as ordered data sets. The proposed method is based on the sliding window technique, defines a new type of correlation measure and can be applied to time series from all domains of science and technology, experimental or simulated. A specific parameter that can characterize the time series is computed for each window and a cross correlation analysis is carried out on the set of values obtained for the time series under investigation. We apply this method to the study of some currency daily exchange rates from the point of view of the Hurst exponent and the intermittency parameter. Interesting correlation relationships are revealed and a tentative crisis prediction is presented.

On the spillover of exchange rate risk into default risk

Directory of Open Access Journals (Sweden)

Božović Miloš

2009-01-01

Full Text Available In order to reduce the exchange-rate risk, banks in emerging markets are typically denominating their loans in foreign currencies. However, in the event of a substantial depreciation of the local currency, the payment ability of a foreign-currency borrower may be reduced significantly, exposing the lender to additional default risk. This paper analyses how the exchange-rate risk of foreign currency loans spills over into default risk. We show that in an economy where foreign currency loans are a dominant source of financing economic activity, depreciation of the local currency establishes a negative feedback mechanism that leads to higher default probabilities, reduced credit supply, and reduced growth. This finding has some important implications that may be of special interest for regulators and market participants in emerging economies.

Due to basic processes of psychological essentialism and contagion, one particular token of monetary currency is not always interchangeable with another piece of currency of equal economic value. When money loses its physical form it is perceived as "not quite the same" money (i.e., to have partly lost the original essence that distinguished it…

Modeling emotional dynamics : currency versus field.

Energy Technology Data Exchange (ETDEWEB)

Sallach, D .L.; Decision and Information Sciences; Univ. of Chicago

2008-08-01

Randall Collins has introduced a simplified model of emotional dynamics in which emotional energy, heightened and focused by interaction rituals, serves as a common denominator for social exchange: a generic form of currency, except that it is active in a far broader range of social transactions. While the scope of this theory is attractive, the specifics of the model remain unconvincing. After a critical assessment of the currency theory of emotion, a field model of emotion is introduced that adds expressiveness by locating emotional valence within its cognitive context, thereby creating an integrated orientation field. The result is a model which claims less in the way of motivational specificity, but is more satisfactory in modeling the dynamic interaction between cognitive and emotional orientations at both individual and social levels.

The U.S. dollar value of gasoline: Currency crisis in Europe

International Nuclear Information System (INIS)

Anon.

1992-01-01

The recent currency crisis in Europe puts the possibility of European economic union in further jeopardy after the Maastricht Treaty was not approved by the Netherlands earlier this Summer. The increased value of European currencies relative to the US dollar during the past Summer had little effect upon national currency gasoline prices. However, the recent currency devaluations in Italy, Spain, and Portugal, already struggling with weak economies, definitely reduce consumer buying power. Governments may use the high taxes imposed on gasoline as a buffer against higher prices, but still, consumers may buy less gasoline as their money doesn't go as far as it once did. This issue also presents the following: (1) the ED Refining Netback Data Series for the US Gulf and West Coasts, Rotterdam, and Singapore as of Sept. 25, 1992; and (2) the ED Refining Netback Data Series for countries of the Eastern Hemisphere, Sept. 1992 Edition

The coherent μ-e conversion rate for general LFV interactions for various nuclei is calculated. The branching ratio increases for the light nuclei such as Z ∼ 60. Although this tendency of Z dependence is the same for different types of coupling constants, there are significant differences in Z dependence of branching ratios. The atomic number dependence of the conversion ratio calculated here is useful to distinguish theoretical models with lepton flavour violation

Dynamically Hedging Oil and Currency Futures Using Receding Horizontal Control and Stochastic Programming

Science.gov (United States)

Cottrell, Paul Edward

There is a lack of research in the area of hedging future contracts, especially in illiquid or very volatile market conditions. It is important to understand the volatility of the oil and currency markets because reduced fluctuations in these markets could lead to better hedging performance. This study compared different hedging methods by using a hedging error metric, supplementing the Receding Horizontal Control and Stochastic Programming (RHCSP) method by utilizing the London Interbank Offered Rate with the Levy process. The RHCSP hedging method was investigated to determine if improved hedging error was accomplished compared to the Black-Scholes, Leland, and Whalley and Wilmott methods when applied on simulated, oil, and currency futures markets. A modified RHCSP method was also investigated to determine if this method could significantly reduce hedging error under extreme market illiquidity conditions when applied on simulated, oil, and currency futures markets. This quantitative study used chaos theory and emergence for its theoretical foundation. An experimental research method was utilized for this study with a sample size of 506 hedging errors pertaining to historical and simulation data. The historical data were from January 1, 2005 through December 31, 2012. The modified RHCSP method was found to significantly reduce hedging error for the oil and currency market futures by the use of a 2-way ANOVA with a t test and post hoc Tukey test. This study promotes positive social change by identifying better risk controls for investment portfolios and illustrating how to benefit from high volatility in markets. Economists, professional investment managers, and independent investors could benefit from the findings of this study.

Four currencies outside the eurozone

Directory of Open Access Journals (Sweden)

Imre Vámos

2015-12-01

Full Text Available Purpose - In the European Union only a few countries have remained outside the eurozone. Among these countries with independent monetary policies few pursue a floating exchange rate regime: the Czech Republic, Hungary, Poland and Romania (IMF, 2013. The purpose of the paper is to examine whether there is a cointegrating relationship between the same underlying economic fundamentals and the real and nominal exchange rate of these countries against the euro. Design/methodology/approach – The quarterly data used for analysis for the period between 2000 and 2014 were provided by the Eurostat and European economy databases. After testing for unit root in the logarithmised data series Engel-Granger and Johansen tests are applied to discover the existence of longrun equilibrium relationships between the exchange rates and fundamentals explaining balance of payments equilibrium. Findings –Based on a uniform behavioural exchange rate model cointegration can only be revealed in the case of the Polish nominal exchange rate data, though simple OLS estimations indicate a strong relationship between fundamentals and exchange rates in the case of all the four countries. Research limitations/implications – The paper points out that it is difficult to prove the existence of any such relationship: making forecasts of the paths of equilibrium exchange rates is hampered by the lack of an adequate model, the short time series and the strong volatility of these currencies, especially the Hungarian forint and the Romanian leu. Another reason for the low explanatory value of various models can be frequent central bank intervention. Originality/value – As Dick et al. (2015 reveals good exchange rate estimates rely on the forecasters ability to understand the relation between fundamentals and the exchange rates mostly in times when exchange rate more strongly deviate from their PPP value. Therefore, applying more approaches for exchange rate analysis helps us

THE LIMITATIONS IN THE APPLICATION OF THE CURRENCY CLAUSE BY THE PRINCIPLES WITH MORALCONTENT

Directory of Open Access Journals (Sweden)

Ivan Akrap

2015-01-01

Full Text Available The provision, which allows the use of currency clause in the Republic of Croatia is introduced in the Law on Obligations in 1994 with the purpose to realize the principle of equal value of performances, in order to protect creditors from the depreciation of the national currency. At the same time no limitations were prescribed in the application of the currency clause, which can, in the different circumstances, lead to a disproportion in the rights and obligations of the parties, on the damage of the debtor. This paper will analyze the economic, social and legal reasons for the introduction of the foreign currency clause in Law, and the importance of legal rules of business with moral content as the limitations of rights based on currency clause during execution of the contract. For that purpose, the general Civil Law rules will be restricted from the separate fields of law, which seek to protect consumers and traders. Furthermore, the authors will examine the possibilities of the protection by these special branches of law against unfair practice during contractual relations with currency clause in Croatian, European and International Law. The authors will observe the recent case law, which classify contracts with a foreign currency clause as the contract with aleatory elements. In conclusion, it would be given the answer to the question whether the basic principles with moral content limit the application of the currency clause.

Full Text Available The relevance of the article’s topic is determined by the aggravation of the monetary and financial crisis in Ukraine and the need to overcome imbalances arising from the complications of circuit of financial capital and its involvement by economic entities. The article is aimed at researching on the basis of technical analysis the influence of exchange rate factor on the formation of capital in the country. The general and distinctive features of technical and fundamental analysis of currency markets are defined. It is shown that despite the difference of views, technical analysis is an integral stage of forecasting the exchange rate. The main scientific result of the article is substantiating the temporary lags of fractals, which explain the change in the dynamics of the exchange rate and their impact on the circuit of financial capital. It has been proved that the systemic crisis in the currency market of Ukraine arose during 2012–2014, with its peak at the end of the specified period. To stop devaluation processes and to provide measures on regulation of the foreign exchange market it has been proposed to soften the conditions of doing business, to improve the methodology of quantitative and qualitative forecasting of the NBU exchange rates, to form system of foreign exchange risk insurance instruments, to increase international reserves to a secure level, etc. Prospect for further research is determining the impact of currency fluctuations on the financial performance of the use of capital of Ukrainian economic entities.

THE ROLE OF MODERN WORLD CURRENCIES IN PRIVATE SECTOR

Directory of Open Access Journals (Sweden)

Inna Kudryashova

2018-01-01

Full Text Available The authors compare the factors determining the scale of international world currencies transactions as saving means and means of payment. The change in the role of the US dollar, euro, pound sterling, Japanese Yen and Chinese Yuan in the private sector over the past few decades are also juxtaposed with the previous factors. The conclusion is made about an incomplete correlation of modern conditions determining the international demand for a common European and Chinese national currency, and the demand for the volumes of their use in the world. On the basis of the comparative analysis of the volumes of world currencies transactions in different spheres, the authors demonstrate the top priority of the means of payment function in the process of calling forth the demand for these means on the part of non-residents using them as payment and saving means. It is proved that the main reasons of maintaining the dominant role of the US dollar as a world currency in the private sector are the leading position of the American economy concerning its contribution into the creation of the world product, support of a relatively high level of the development of the national financial market of the USA, long-term period of the American currency being world unit of account, low operation costs concerning the operations with them and also the inertia character of private actors of the world economy. It is shown that in a short-term period in case of a further growth of the economic power of the euro zone and China, provision of a complete convertibility of the Yuan and removal of the restrictions for non-residents in the Chinese financial market and also in case of maintaining a stable economic situation in the USA, the function of the world money will be carried out mainly by the American dollar.

A Proposed Solution for the Chicken-Egg Dilemma in Pricing Currency Options

Directory of Open Access Journals (Sweden)

Ariful Hoque

2013-06-01

Full Text Available The implied volatility (IV estimation process suffers from an obvious chicken-egg dilemma: obtaining an unbiased IV requires the options to be priced correctly and calculating an accurate option price (OP requires an unbiased IV. We address this critical issue in two steps. First, the Granger causality test is employed, whichconfirms the chicken-and-egg problem in the IV computing process. Secondly, the concept of “moneyness volatility (MV” is introduced as an alternative to IV. MV is modelled based on an option’s moneyness (OM during the life of the option’s contract. The F-test, Granger-Newbold test and Diebold-Mariano test results consistently show that MV outperforms IV in estimating the exchange rate volatility for pricing options. Further, these series of tests across six major currency options substantiate the validity as well as the reliability of the results. We posit that MV offers a unique solution for pricing currency options accurately.

Currency crises and the evolution of foreign exchange market: Evidence from minimum spanning tree

Jang, Wooseok; Lee, Junghoon; Chang, Woojin

2011-02-01

We examined the time series properties of the foreign exchange market for 1990-2008 in relation to the history of the currency crises using the minimum spanning tree (MST) approach and made several meaningful observations about the MST of currencies. First, around currency crises, the mean correlation coefficient between currencies decreased whereas the normalized tree length increased. The mean correlation coefficient dropped dramatically passing through the Asian crisis and remained at the lowered level after that. Second, the Euro and the US dollar showed a strong negative correlation after 1997, implying that the prices of the two currencies moved in opposite directions. Third, we observed that Asian countries and Latin American countries moved away from the cluster center (USA) passing through the Asian crisis and Argentine crisis, respectively.

Proposed currency composite approach to pricing OPEC oil: problems and possibilities

Energy Technology Data Exchange (ETDEWEB)

Shaaf, M.B.

1982-01-01

The primary purpose of this dissertation was to explore the nature, purposes, benefits, and barriers of establishing a currency basket for OPEC as an alternative to the use the dollar for international trade in oil. The study included the construction and evaluation of three alternative currency baskets and the evaluation of two other baskets for the protection of the real price of OPEC oil from foreign-exchange fluctuations between 1971 and 1980. A secondary objective was to assess the inflationary impact on the real price of oil. Finally, the purpose was to evaluate the changes of the terms of trade of OPEC during the same period. The findings of the research are as follows: During 1971-1980, inflation and the relative weakness of the dollar have reduced the real price of oil to OPEC. In spite of this, the terms of trade of OPEC have substantially improved. This was because OPEC increased its oil prices much more than sufficient to compensate for inflation and the fluctuation of foreign-exchange rates.

2013-01-01

Full Text Available Small oscillations of exchange rate certainly affect the loss of confidence in the currency (Serbian dinar, CSD and because of the shallow market even the smallest change in the supply and demand leads to a shift in exchange rate and brings uncertainty. Some economists suggest that the course should be linked to inflation and thus ensure predictable and stable exchange rates. Real exchange rate or slightly depressed exchange rate will encourage the competitiveness of exporters and perhaps ensure the development of new production lines which, in terms of overvalued exchange rate, had no economic justification. Fixed exchange rate will bring lower interest rates, lower risk and lower business uncertainty (uncertainty avoidance, but Serbia will also reduce foreign exchange reserves by following this trend. On the other hand, a completely free exchange rate, would lead to a (real fall of Serbian currency, which in a certain period would lead to a significant increase in exports, but the consequences for businessmen and citizens with loans pegged to the euro exchange rate, would be disastrous. We will pay special attention to the depreciation of the exchange rate, as it is generally favorable to the export competitiveness of Serbia and, on the other hand, it leads to an increase in debt servicing costs of the government as well as of the private sector. Oscillations of the dinar exchange rate, appreciation and depreciation, sometimes have disastrous consequences on the economy, investors, imports and exports. In subsequent work, we will observe the movement of the dinar exchange rate in Serbia, in the time interval 2009-2012, in order to strike a balance and maintain economic equilibrium. A movement of foreign currencies against the local currency is controlled in the foreign exchange market, so in case economic interests require, The National Bank of Serbia (NBS, on the basis of arbitrary criteria, can intervene in the market.

TRIPOLARISATION OF THE CURRENCIES IN THE WORLD ECONOMY: US DOLLAR – EURO – YEN

Directory of Open Access Journals (Sweden)

Ramona TOMA

2006-12-01

Full Text Available At present, the world economy is dominated by three poles – the USA, the European Union and Japan – among which there should be real co-operation to ensure the international stability on all levels. The introduction of the euro was perceived by the experts as the beginning of the competition among the currencies on the international financial markets. The European Monetary Union was conceived to cause an internal, not an external change, with an economic and financial purpose and as a further step of the European integration. Moreover, the international monetary system does not allow the European single currency to make gains that might cause losses to the US dollar. Both currencies have room in the world economy, but the euro has been beneficial to both the euro area and the rest of the world. At present, the euro is stronger than the sum of the twelve former national currencies. The consolidation of the national economies of the euro area becomes stronger due to the impact on liquidities, to the various investment opportunities for the entities that manage the financial portfolios and the central banks that manage the foreign currency reserves. The competition among the currencies means more opportunities in the world economy: the euro is an international currency used along with the US dollar and the yen, not against them.

1988-02-01

Conversion factors necessary for estimating release rate of gaseous radioactivity by an aerial survey are presented. The conversion factors were determined based on calculation assuming a Gaussian plume model as a function of atmospheric stability, down-wind distance and flight height. First, the conversion factors for plumes emitting mono-energy gamma rays were calculated, then, conversion factors were constructed through convolution for the radionuclides essential in an accident of a nuclear reactor, and for mixtures of these radionuclides considering elapsed time after shutdown. These conversion factors are shown in figures, and also polynomial expressions of the conversion factors as a function of height have been decided with the least-squares method. A user can easily obtain proper conversion factors from data shown here. (author)

The Measurement of Co-Circulation of Currencies and Dollarization in the Republic of Armenia

Directory of Open Access Journals (Sweden)

Hakob Zoryan

2005-06-01

Full Text Available This paper attempts to estimate the actual (de facto level of dollarization in Armenia. “Co-circulation” involves the regular use of two or more currencies within an economy. The existence of an unknown amount of foreign currency in circulation makes the outcome of domestic monetary policy uncertain. The volume of foreign currency deposits is easily obtained from the official statistics. However, it is very hard to determine the stock of foreign currency in circulation. The effective money supply may be much larger than the domestic money supply and is subject to behavioral responses which are very different than the movements of the presently measured money supply. The purpose of this paper is to assess the level of dollarization, that is, to evaluate the size and/or proportion of foreign currency in the total money stock of Armenia as a highly dollarized country.

Real purchasing power of oil revenues for OPEC Member Countries: a broad currency basket and dynamic trade pattern approach

International Nuclear Information System (INIS)

Mazraati, M.

2005-01-01

The purpose of this paper is to examine the real purchasing power of OPEC Member Countries' oil revenues, which are subject to 'the value of the US dollar vis-a-vis other major currencies' and 'world imported inflation'. The exponential weighting average formula with a broad basket of currencies is suggested. The basket of currencies is labelled as a broad currency basket and includes the major trading partners of OPEC Member Countries. The weights are normalized OPEC import shares of the countries of the basket and are updated and adjusted every year to incorporate a gradual change in the trade pattern. In other words, the dynamic trade pattern approach is incorporated in the calculations. The nominal dollar oil revenues of OPEC Member Countries are about $5,099 billion during 1970 to 2004, of which $3,725 bn (73 per cent) have been lost due to imported inflation and the dollar's depreciation. Imported inflation and dollar depreciation have had a respective 78.6 per cent and 21.4 per cent contribution to the losses of the purchasing power of OPEC Member Countries. The imported inflation rate approaches a stable low level, but OPEC still has a lot of concerns on dollar swings. The euro offers opportunities for many oil-exporting nations that have extensive trade relations with Euro-zone countries. Payments for oil exports can be invoked in euros at the prevailing dollar-euro rate on the day of a given contract, or any other trigger formula. This would immunize a major portion of OPEC oil revenues from dollar depreciation. (author)

Suharsono, Agus; Suhartono, Masyitha, Aulia; Anuravega, Arum

2015-12-01

The purpose of the study is to forecast the outflow and inflow of currency at Indonesian Central Bank or Bank Indonesia (BI) in Sulawesi Region. The currency outflow and inflow data tend to have a trend pattern which is influenced by calendar variation effects. Therefore, this research focuses to apply some forecasting methods that could handle calendar variation effects, i.e. Time Series Regression (TSR) and ARIMAX models, and compare the forecast accuracy with ARIMA model. The best model is selected based on the lowest of Root Mean Squares Errors (RMSE) at out-sample dataset. The results show that ARIMA is the best model for forecasting the currency outflow and inflow at South Sulawesi. Whereas, the best model for forecasting the currency outflow at Central Sulawesi and Southeast Sulawesi, and for forecasting the currency inflow at South Sulawesi and North Sulawesi is TSR. Additionally, ARIMAX is the best model for forecasting the currency outflow at North Sulawesi. Hence, the results show that more complex models do not neccessary yield more accurate forecast than the simpler one.

Intertemporal Risk-Return Trade-off in Foreign Exchange Rates

Christiansen, Charlotte

2010-01-01

We investigate the intertemporal risk-return trade-off of foreign ex-change (FX) rates for ten currencies quoted against the USD. For each currency,we use three risk measures simultaneously that pertain to that currency; its re-alized volatility, its realized skewness, and its value-at-risk. We apply monthlyFX excess returns and monthly FX risk measures calculated from daily ob-servations. We find that there is a positive and signi…cant contemporaneousrisk-return trade-off for most currencies...

Forecasting volatility of traditional financial instruments is a well known and widely addressed problem. In the past, researches addressed it by using technical and fundamental analysis. The former looks at the past price movement of a currency or a stock (their market value and trading volumes), while the latter analyses outside information which can cause fluctuations in the currency or stock value (e.g.: introducing a new product in the company can increase the value of company’s stocks, ...

Market based resource allocation mechanisms require mechanisms to regulate and manage the usage of traded resources. One mechanism to control this is the definition of some kind of currency. Within this context, we have implemented a first prototype of our Currency Management System, which stands for a decentralized and scalable banking service for the Grid. Basically, our system stores user accounts within a DHT and its basic operation is the transferFunds which, as its name suggests, transf...

Inference of financial networks using the normalised mutual information rate

Science.gov (United States)

2018-01-01

In this paper, we study data from financial markets, using the normalised Mutual Information Rate. We show how to use it to infer the underlying network structure of interrelations in the foreign currency exchange rates and stock indices of 15 currency areas. We first present the mathematical method and discuss its computational aspects, and apply it to artificial data from chaotic dynamics and to correlated normal-variates data. We then apply the method to infer the structure of the financial system from the time-series of currency exchange rates and stock indices. In particular, we study and reveal the interrelations among the various foreign currency exchange rates and stock indices in two separate networks, of which we also study their structural properties. Our results show that both inferred networks are small-world networks, sharing similar properties and having differences in terms of assortativity. Importantly, our work shows that global economies tend to connect with other economies world-wide, rather than creating small groups of local economies. Finally, the consistent interrelations depicted among the 15 currency areas are further supported by a discussion from the viewpoint of economics. PMID:29420644

2017-01-01

Full Text Available Transactions involving virtual currencies are becoming increasingly common, including those in online games. In response, predicting the market price of a virtual currency is an important task for all involved, but it has not yet attracted much attention from researchers. This paper presents user opinions from online forums in a massive multiplayer online game (MMOG setting widely used around the world. We propose a method for predicting the next-day rise and fall of the currency used in an MMOG environment. Based on analysis of online forum users’ opinions, we predict daily fluctuations in the price of a currency used in an MMOG setting. Focusing specifically on the World of Warcraft game, one of the most widely used MMOGs, we demonstrate the feasibility of predicting the fluctuation in value of virtual currencies used in this game community.

The US won the global currency war against Europe and Japan: Their retaliation likely helped elect Trump

Directory of Open Access Journals (Sweden)

Stephen P. Magee

2017-11-01

Full Text Available The United States financial community, lax regulations and the Fed started a global currency war in 2002. The inadvertent cheapening of the US dollar was a by-product of what became the US subprime lending crisis and the financial collapse in 2008. From 2002-2008, the Fed created so much liquidity that the dollar fell 33% relative to the yen and 40% relative to the euro. In response to the 2008 crash, the Fed had to ramp up US money creation again, generating $4 trillion in money creation by 2014. World interest rates fell and raw materials and commodity producers in emerging markets borrowed nearly $5 trillion. Overproduction and the slowdown of China caused a Third World oil and commodity market collapse around 2015. Beginning in 2014, other advanced countries retaliated and declared a global currency war of their own against United States. They created their money with a vengeance. Just as the US had done, this made the currencies of Europe, Japan and Britain 20 to 25% cheaper and their goods became more competitive relative to US goods. As a result, the US became the importer of last resort for cheap foreign goods from 2014 until the election in November of 2016. Only time will tell whether the US currency war that we won from 2002-2014 and the retaliation war we lost from 2014-2016 helped Trump get elected. The parallel is inescapable that the US also started the world tariff and trade war in 1930 with the passage of the Smoot Hawley tariff, which extended the length of the Great Depression. The US currency war pushed Japan even further into recession and weakened Europe. US quantitative easing became a beggar-thy-neighbor policy against our trading partners.

Assessing the Efficacy of Adjustable Moving Averages Using ASEAN-5 Currencies.

Full Text Available The objective of this research is to examine the trends in the exchange rate markets of the ASEAN-5 countries (Indonesia (IDR, Malaysia (MYR, the Philippines (PHP, Singapore (SGD, and Thailand (THB through the application of dynamic moving average trading systems. This research offers evidence of the usefulness of the time-varying volatility technical analysis indicator, Adjustable Moving Average (AMA' in deciphering trends in these ASEAN-5 exchange rate markets. This time-varying volatility factor, referred to as the Efficacy Ratio in this paper, is embedded in AMA'. The Efficacy Ratio adjusts the AMA' to the prevailing market conditions by avoiding whipsaws (losses due, in part, to acting on wrong trading signals, which generally occur when there is no general direction in the market in range trading and by entering early into new trends in trend trading. The efficacy of AMA' is assessed against other popular moving-average rules. Based on the January 2005 to December 2014 dataset, our findings show that the moving averages and AMA' are superior to the passive buy-and-hold strategy. Specifically, AMA' outperforms the other models for the United States Dollar against PHP (USD/PHP and USD/THB currency pairs. The results show that different length moving averages perform better in different periods for the five currencies. This is consistent with our hypothesis that a dynamic adjustable technical indicator is needed to cater for different periods in different markets.

Kessing, Lars Vedel; Willer, Inge; Andersen, Per Kragh; Bukh, Jens Drachman

2017-08-01

For the first time to present a systematic review and meta-analysis of the conversion rate and predictors of conversion from unipolar disorder to bipolar disorder. A systematic literature search up to October 2016 was performed. For the meta-analysis, we only included studies that used survival analysis to estimate the conversion rate. A total of 31 studies were identified, among which 11 used survival analyses, including two register-based studies. The yearly rate of conversion to bipolar disorder decreased with time from 3.9% in the first year after study entry with a diagnosis of unipolar disorder to 3.1% in years 1-2, 1.0% in years 2-5 and 0.8% in years 5-10. A total of eight risk factors were evaluated comprising gender, age at onset of unipolar disorder, number of depressive episodes, treatment resistance to antidepressants, family history of bipolar disorder, the prevalence of psychotic depression, the prevalence of chronic depression, and severity of depression. It was not possible to identify risk factors that were consistently or mainly confirmed to predict conversion across studies. The conversion rate from unipolar to bipolar disorder decreases with time. It was not possible to identify predictors of conversion that were consistently or mainly confirmed across studies, which may be due to variations in methodology across studies. © 2017 John Wiley & Sons A/S.

Currencies of Science: discussing disciplinary “exchange rates” for citations and Mendeley readership

Energy Technology Data Exchange (ETDEWEB)

Costas, R.; Perianes-Rodriguez, A.; Ruiz-Castillo, J.

2016-07-01

In 1998 Garfield stated that “[t]he Mertonian description of normal science describes citations as the currency of science. Scientists make payments, in the form of citations, to their preceptors”. The idea of citations as a currency of science was also discussed by Wouters (1999) who suggested that the “role of the citation might also be compared with that of money, especially if the evaluative use of scientometrics is taken into account. Whenever the value of an article is expressed in its citation frequency, the citation is probably the most important unit of a ‘currency of science’”. Thus, citations have been seen as currency able to reward scientists for their work and scientific merit, being an integral part, together with authorship and acknowledgements, of the so-called “reward triangle” (Cronin & Weaver, 1995)2. This role of citations as main currency in evaluative scientometrics has gone unchallenged until recently. The emergence of new ways of measuring the reception of scientific publications by different audiences in the form of the so-called “altmetrics” (Haustein, et al. 2015a; Priem, et al. 2010) probably represents the most important attempt of expanding the system of currencies of science. However, research on altmetrics suggest that there are critical differences with citations: in coverage (Thelwall, et al. 2013), main characteristics (Haustein, et al., 2015), correlations (Costas, et al. 2015b; Haustein, et al. 2014), and interpretation (Haustein et al., 2016). These results essentially highlight the limited potential of most of these metrics as realistic alternatives to citations. (Author)

In this paper, we derive the dynamics and assess the economic value of currency speculation by formalizing the concept of a trader inaction range. We show that exchange rate returns comprise a time-varying risk-premium and that uncovered interest parity (UIP) holds in a speculative sense. The often......-cited ‘forward bias puzzle’ originates from the omission of the risk-premium in standard UIP tests. Consistent with its popularity among market professionals, the carry-trade strategy can be rationalized as it systematically collects risk-premia, however, the economic value generated by bilateral carry-trades...

The currency risk relates to these cases when investor converts cash from and into domestic currency. The currency risk is determined by unexcepeted change of exchange rate (currency of financial asset denomination / investor’s domestic currency during duration of the investment.Objective of the paper is quantification and analysis of exchange rate EUR/USD impact on the rate of return of bond investments denominated in US dollar from the point of view of a euro investor for investment horizons of different length.The analysis is realized for following investment horizons: 1 year, 2 years, 3 years, 5 years, 7 years, 10 year and 12 year. Complementary investment horizons are: month and 15 year. Bond investments denominated just US dollar are represented by investments into ING bond unit trust in period December 1989–December 2007. The unit trust invests into bonds with high rating (for example governmants bonds etc.. These bonds are denominated in USD only. Methodology of the analysis is based on quantification of proportion of exchange rate EUR/USD impact on the rate of return of bond investment denominated in USD. The share is based on basic piece of knowledge of the uncovered interest rate parity.

The roughness exponent H1 which characterizes the excursion of the exchange rate has been numerically measured. The degree of intermittency C1 has been also estimated. In the (H1,C1) phase diagram, the currency exchange rates are dispersed in a wide region around the Brownian motion value (H1=0.5,C1=0) and have a significantly intermittent component (C1≠0).

Foreign currency rate forecasting using neural networks

2000-03-01

Neural networks are increasingly being used as a forecasting tool in many forecasting problems. This paper discusses the application of neural networks in predicting daily foreign exchange rates between the USD, GBP as well as DEM. We approach the problem from a time-series analysis framework - where future exchange rates are forecasted solely using past exchange rates. This relies on the belief that the past prices and future prices are very close related, and interdependent. We present the result of training a neural network with historical USD-GBP data. The methodology used in explained, as well as the training process. We discuss the selection of inputs to the network, and present a comparison of using the actual exchange rates and the exchange rate differences as inputs. Price and rate differences are the preferred way of training neural network in financial applications. Results of both approaches are present together for comparison. We show that the network is able to learn the trends in the exchange rate movements correctly, and present the results of the prediction over several periods of time.

Oil price fluctuations and U.S. dollar exchange rates

International Nuclear Information System (INIS)

2010-01-01

Adding oil prices to the monetary model of exchange rates, we find that oil prices significantly explain movements in the value of the U.S. dollar (USD) against major currencies from the 1970s to 2008. Our long-run and forecasting results are remarkably consistent with an oil-exchange rate relationship. Increases in real oil prices lead to a significant depreciation of the USD against net oil exporter currencies, such as Canada, Mexico, and Russia. On the other hand, the currencies of oil importers, such as Japan, depreciate relative to the USD when the real oil price goes up. (author)

Effects of Current Forward Market Intervention in the Korean Currency Crisis

Directory of Open Access Journals (Sweden)

Woosik Moon

2001-06-01

Full Text Available This paper investigates the effect of the exchange market interventions of the Bank of Korea on the exchange rate of Korean won vis-a-vis US dollar during the 1997 currency crisis. In particular, this paper tests the effects of spot and forward market interventions, using daily intervention data of the Bank of Korea. During the 1997 period, Korea faced two series of crisis in January-March and September-November. It turns out that the spot market intervention was effective in stabilizing the spot market exchange rate at least during the first crisis period. In contrast, there seemed no effect of the forward market intervention. Forward market intervention was rather destabilizing through forward exchange rate during the second crisis period. This implies that even though the forward and sterilized spot market interventions are equivalent in their effect on exchange rate, these two instruments can widely diverge from each other under the circumstances of exchange rate volatility and speculation.

The impact of the financial crisis on the currency and the monetary system

Directory of Open Access Journals (Sweden)

Petre DEACONU

2010-09-01

Full Text Available The present-day economic and financial crisis (depression appears unprecedented in the last half century. The international financial crisis has been extended to the Romanian economy. However, in terms of direct impact, the Romanian banking system was less affected by not being exposed to toxic assets, and because of prudential and administrative measures taken by the NBR. Indirectly, however, the international financial crisis and especially its obvious consequence – the recession in developed countries - has expanded to the Romanian economy, on several channels. The shopping channel slowed export growth and even reduced them. The financial channel has limited the access to external financing, and thus restricted the lending volume, generating private external debt service difficulties. On the exchange rate channel, the reduction in external financing reflected in national currency depreciation. On the confidence channel, there was a withdrawal of investors from Eastern Europe countries. Among the measures adopted by the central bank, the most notable were targeting inflation and currency interventions. By adopting inflation targeting, the central bank opted to make more room in establishing foreign exchange market, and after the onset of the current international financial crisis, including the 2009-2010, adopted a controlled floating exchange rate. This does not mean intervention in the forex market on a discretionary basis. NBR policy on foreign exchange intervention has been guided by the philosophy that high exchange rate volatility is harmful for both the inflation target and the financial health of the real and financial sector.

Modeling of the reactant conversion rate in a turbulent shear flow

Frankel, S. H.; Madnia, C. K.; Givi, P.

1992-01-01

Results are presented of direct numerical simulations (DNS) of spatially developing shear flows under the influence of infinitely fast chemical reactions of the type A + B yields Products. The simulation results are used to construct the compositional structure of the scalar field in a statistical manner. The results of this statistical analysis indicate that the use of a Beta density for the probability density function (PDF) of an appropriate Shvab-Zeldovich mixture fraction provides a very good estimate of the limiting bounds of the reactant conversion rate within the shear layer. This provides a strong justification for the implementation of this density in practical modeling of non-homogeneous turbulent reacting flows. However, the validity of the model cannot be generalized for predictions of higher order statistical quantities. A closed form analytical expression is presented for predicting the maximum rate of reactant conversion in non-homogeneous reacting turbulence.

The underlying assumption is that, on longer timescales EMA is profitable and provides more relevant signals. The second objective of this paper is to test the signals of indicators in different months. It is believed that in September and January the number of trading signals on this indicator will increase. Testing will be done on the five-minute time frame. The test will be subjected to 65,000 rate values of the EUR / USD currency pair. Effectiveness of the analysis will be evaluated on the basis of digital (binary option. Business strategy is based on EMA crossover indicator of current exchange rate. By the contribution there were confirmed hypotheses about more profitable signals when selecting a greater timeframe breadth of moving average. There was also confirmed an increased amount of signals in September, but not in January.

Some of these countries adopted the euro such as the case of Montenegro in 2002, Slovakia in 2009, Estonia in 2011, and finally Latvia in 2014. Adoption of the new currency helped these countries further integrate into a larger market, the Eurozone, and stabilize their economies against heavily fluctuating exchange rates. The governments of Ukraine and Russia, on the other hand, did not show interest to join the Eurozone and followed more independent currency policies along with the limited economic liberalization during the period of the 90s and the early 2000s. Similarly, Turkey, not a former Eastern Bloc country, but located geographically very close to these two countries did not peg its currency to the euro or the US dollar. All of these three economies in Eastern Europe had multiple deep financial crises, inflation, devaluations, and weak governments in the last two decades of the 90s and the 2000s (Lissovolik, 2003. For instance, Turkish lira depreciated from 13 TL/$ in 1973 to 1.5 million TL/$ in 2004 (Bahmani-Oskooee, 1996. As a result, of these negative experiences, local people of these countries developed a tendency to keep at least a portion of their savings in a foreign currency (Civcir, 2003. In the case of Turkey, the ratio of reserves held in the foreign currency over the local currency, which is a de facto measure of US dollarization, showed a steady rise during the period from 1983 to 1993, remained steady high around 50% until 2001 and decreased afterwards (Metin-Özcan, 2009. In short, these countries are examples of highly US dollarized countries (Havrylyshyn & Beddies, 2003; Kaplan, 2008.

2012-01-01

Dispenser is an integrated fuel transport and measurement system at the service station. In this paper, we developed a frequency conversion mode for the dispenser, based on the flow rate signal which is obtained from the converter measuring flow capacity. After introducing the frequency conversion mode to dispenser, we obtained that pump rotates at a high speed when fuelled with high flow rate, and it rotates at a low speed when fuelled with low flow rate. This makes the fuel dispenser more energy-efficient and controllable. We also did some valve optimizations on the dispenser and developed a new control mode for preset refuelling based on the frequency conversion mode, Experimental and theoretical studies have shown that the new dispenser not only can meet the national standards, but also performs better than the ordinary one especially in preset refuelling.

2013-01-01

Derivatives markets in emerging economies have continued to grow since 2010, driven mostly by very strong growth in the OTC market. Emerging market currencies have become more international as offshore markets are a major contributor to FX turnover. The Chinese renminbi is actively traded within emerging Asia. Trading of emerging market currencies is positively related to the size of cross-border financial flows.

Corporate financing strategies employed by Zimbabwean listed firms in the multiple currency era

Farai Kwenda

2015-09-01

Full Text Available The aim of this study is to review the corporate financing strategies employed by Zimbabwean listed firms since the adoption of the multiple currency system which set the country on a recovery path after the decade-long political, social and economic crises. The adoption of the multiple currency system necessitated recapitalization and retooling because most firms’ balance sheets were wiped away during the hyperinflation era. The study is based on secondary data of 80 firms listed on the Zimbabwe Stock Exchange. The study found that rights issues and high retention ratios were the main strategies used by firms to recapitalize their operations. The recapitalization efforts have been by liquidity challenges that have characterised the multiple currency era.

Kocakaplan, Yusuf; Deviren, Bayram; Keskin, Mustafa

2012-12-01

We have examined the hierarchical structures of correlations networks among Turkey’s exports and imports by currencies for the 1996-2010 periods, using the concept of a minimal spanning tree (MST) and hierarchical tree (HT) which depend on the concept of ultrametricity. These trees are useful tools for understanding and detecting the global structure, taxonomy and hierarchy in financial markets. We derived a hierarchical organization and build the MSTs and HTs during the 1996-2001 and 2002-2010 periods. The reason for studying two different sub-periods, namely 1996-2001 and 2002-2010, is that the Euro (EUR) came into use in 2001, and some countries have made their exports and imports with Turkey via the EUR since 2002, and in order to test various time-windows and observe temporal evolution. We have carried out bootstrap analysis to associate a value of the statistical reliability to the links of the MSTs and HTs. We have also used the average linkage cluster analysis (ALCA) to observe the cluster structure more clearly. Moreover, we have obtained the bidimensional minimal spanning tree (BMST) due to economic trade being a bidimensional problem. From the structural topologies of these trees, we have identified different clusters of currencies according to their proximity and economic ties. Our results show that some currencies are more important within the network, due to a tighter connection with other currencies. We have also found that the obtained currencies play a key role for Turkey’s exports and imports and have important implications for the design of portfolio and investment strategies.

The Shadow Economy of Czech Republic and Tax Evasion: The Currency Demand Approach

Directory of Open Access Journals (Sweden)

Dennis Nchor

2016-01-01

Full Text Available This study investigates the shadow economy of Czech Republic and the associated losses in tax revenue. The presence of a shadow economy may not necessarily be bad for the economies in which they prevail but they could cause huge losses to government revenue and could also constitute serious violation of labour regulations. The study uses the Currency Demand Approach. It measures the size of the shadow economy in two stages: a the econometric estimation of an aggregate money demand equation b the calculation of the value of the shadow economy through the quantity theory of money. The key variables in the study include: the total currency held outside the banking system, the number of automatic teller machines, the deposit interest rate, GDP deflator, the average tax, velocity of money, nominal GDP and nominal money supply. The results from the study show that the shadow economy of Czech Republic on the average is about 20.9 % as at the end of 2013 and the country loses an average tax revenue of about 7.2 % of GDP yearly. The data was obtained from the World Bank country indicators and the International Financial Statistics.

Application of the dose rate spectroscopy to the dose-to-curie conversion method using a NaI(Tl) detector

International Nuclear Information System (INIS)

2015-01-01

Dose rate spectroscopy is a very useful method to directly calculate the individual dose rate from the converted energy spectrum for the dose rate using the G-factor which is related to the used detector response function. A DTC conversion method for the estimation of the radioactivity based on the measured dose rate from the radioactive materials can then be modified into a simple equation using the dose rate spectroscopy. In order to make the method validation of the modified DTC conversion method, experimental verifications using a 3″φx3″ NaI(Tl) detector were conducted at the simple geometry of the point source located onto a detector and more complex geometries which mean the assay of the simulated radioactive material. In addition, the linearity about the results from the modified DTC conversion method was also estimated by increasing the distance between source positions and a detector to confirm the method validation in the energy, dose rate, and distance range of the gamma nuclides. - Highlights: • A modified DTC conversion method using the dose rate spectroscopy was established. • In-situ calibration factors were calculated from the MCNP simulation. • Radioactivities of the disk sources were accurately calculated using a modified DTC conversion method. • A modified DTC conversion method was applied to the assay of the radioactive material

2013-02-01

Full Text Available A good portfolio optimization on banks’ currency holdings not only helps meet their needs but also it increases banks’ total assets. During the past few months, US sanctions against Iran has influenced profitability banking currency portfolio holding. The proposed model of this paper considers the weekly information of two years before and after sanctions occurred in Iranian banking system. Therefore, the study uses 210 weekly data and proposes a method to analyze the data to measure the performance of banking currency portfolio after sanction happens. The proposed model of this paper provides lost profit and unrealized loss and using the idea of Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS we rank the resulted data. Next, we use some parametric and non-parametric methods to see whether there is any change as a result of sanction on the performance of the portfolio. The results indicate that not only the performance of the portfolio was reduced but also the variance of the return after sanction has been increased.

A conversion operator between spectrum and exposure rate, using a portable HPGe detector for environmental radiation monitoring, was determined theoretically under the assumption of uniform distribution of radiation source on the ground surface. The measurement results were compared with those of a pressurized ionization chamber. The results obtained with the HPGe detector were slightly lower. The method can be easily applied to any gamma ray detector to obtain a spectrum - exposure-rate conversion factor for computing the exposure rate of environmental gamma radiation.

Searching for an Appropriate Exchange Rate Regime

Directory of Open Access Journals (Sweden)

Yunjong Wang

2001-06-01

Full Text Available This paper attempts to survey current debates on the choice of exchange rate regime in emerging market economies. The issue of choosing an appropriate exchange rate regime is being actively discussed since the recent Asian crisis. As a lesson from the recent crises, one widely shared conclusion is that soft peg exchange rate regimes are extremely vulnerable in a world of volatile capital movements. Consequently, new orthodoxy based on the impossible trinity hypothesis favours two corner solutions ― greater flexibility or credible institutional assurance, like a currency board system or dollarization. Nevertheless, questions whether such corner solutions are adequate for developing countries are rising of late. "Fear of floating" is still conspicuous in many developing countries having adopted nominally a free-floating exchange rate regime. Developing countries are sensitive to exchange rate fluctuations because the cost of exchange rate volatility is greater than the benefit when compared to developed countries. Monitoring bands is a compromise solution, but it still needs further enhancement of estimation techniques for fundamental equilibrium exchange rates in order to make those estimation results more workable in practice. Other alternatives include the creation of soft peg of the G-3 currencies. Despite counterarguments, the stability of G-3 currencies could prove to be beneficial to emerging market economies.

Recently, it has been shown that inter-transaction interval (ITI) distribution of foreign currency rates has a fat tail. In order to understand the statistical property of the ITI dealer model with N interactive agents is proposed. From numerical simulations it is confirmed that the ITI distribution of the dealer model has a power law tail. The random multiplicative process (RMP) can be approximately derived from the ITI of the dealer model. Consequently, we conclude that the power law tail of the ITI distribution of the dealer model is a result of the RMP.

RECENT APPROACHES IN THE OPTIMUM CURRENCY AREAS THEORY

Full Text Available This study is dealing with the endogenous characteristic of the OCA criteria, starting from the idea that a higherconformity of the business cycles will result in a better timing of the economic cycles and, thus, in getting closerto the quality of an optimum currency area. Thus, if the classical theory is focused on a static approach of theproblem, the new theories assert that these conditions are dynamic, and they cannot be positively affected evenby the establishment of the Economic and Monetary Union. The consequences are overwhelming, as theendogenous approach shows that a monetary union can be achieved even if all the conditions mentioned inMundell’s optimum currency areas theory are not met, showing that some of them may also be met subsequentto the unification. Thus, a country joining a monetary union, althogh it does not meet the criteria for an optimumcurrency area, will ex post lead to the increase of the integration and business cycle correlation degree.

Money currency availability in Bank Indonesia can be examined by inflow and outflow of money currency. The objective of this research is to forecast the inflow and outflow of money currency in each Representative Office (RO) of BI in East Java by using a hybrid exponential smoothing based on state space approach and calendar variation model. Hybrid model is expected to generate more accurate forecast. There are two studies that will be discussed in this research. The first studies about hybrid model using simulation data that contain pattern of trends, seasonal and calendar variation. The second studies about the application of a hybrid model for forecasting the inflow and outflow of money currency in each RO of BI in East Java. The first of results indicate that exponential smoothing model can not capture the pattern calendar variation. It results RMSE values 10 times standard deviation of error. The second of results indicate that hybrid model can capture the pattern of trends, seasonal and calendar variation. It results RMSE values approaching the standard deviation of error. In the applied study, the hybrid model give more accurate forecast for five variables : the inflow of money currency in Surabaya, Malang, Jember and outflow of money currency in Surabaya and Kediri. Otherwise, the time series regression model yields better for three variables : outflow of money currency in Malang, Jember and inflow of money currency in Kediri.

Full Text Available Currency notes have been implicated as a vehicle for transmitting community-acquired bacterial infections. However, the overall diversity of the bacterial population residing on banknotes is still unknown in Brazil. In this study, we aimed to investigate the overall bacterial population from 150 different Brazilian Rial (R$ notes in circulation using a culture-independent Illumina massively parallel sequencing approach of the 16S rRNA genes. Samples were randomly collected from three different street markets or “feiras” in the metropolitan region of São Paulo. Taxonomical composition revealed the abundance of Proteobacteria phyla, followed by Firmicutes and Streptophyta, with a total of 1193 bacterial families and 3310 bacterial genera. Most of these bacterial genera are of human, animal, and environmental origins. Also, our analysis revealed the presence of some potential pathogenic bacterial genera including Salmonella, Staphylococcus, and Klebsiella. The results demonstrate that there is a tremendous diversity of bacterial contamination on currency notes, including organisms known to be opportunistic pathogens. One of the factors that may contribute to the richness of bacterial diversity in currency notes is personal hygiene. Thus, our results underscore the need to increase public awareness of the importance of personal hygiene of money handlers who also handle food.

Linear constraint relations in biochemical reaction systems: I. Classification of the calculability and the balanceability of conversion rates.

van der Heijden, R T; Heijnen, J J; Hellinga, C; Romein, B; Luyben, K C

1994-01-05

Measurements provide the basis for process monitoring and control as well as for model development and validation. Systematic approaches to increase the accuracy and credibility of the empirical data set are therefore of great value. In (bio)chemical conversions, linear conservation relations such as the balance equations for charge, enthalpy, and/or chemical elements, can be employed to relate conversion rates. In a pactical situation, some of these rates will be measured (in effect, be calculated directly from primary measurements of, e.g., concentrations and flow rates), as others can or cannot be calculated from the measured ones. When certain measured rates can also be calculated from other measured rates, the set of equations, the accuracy and credibility of the measured rates can indeed be improved by, respectively, balancing and gross error diagnosis. The balanced conversion rates are more accurate, and form a consistent set of data, which is more suitable for further application (e.g., to calculate nonmeasured rates) than the raw measurements. Such an approach has drawn attention in previous studies. The current study deals mainly with the problem of mathematically classifying the conversion rates into balanceable and calculable rates, given the subset of measured rates. The significance of this problem is illustrated with some examples. It is shown that a simple matrix equation can be derived that contains the vector of measured conversion rates and the redundancy matrix R. Matrix R plays a predominant role in the classification problem. In supplementary articles, significance of the redundancy matrix R for an improved gross error diagnosis approach will be shown. In addition, efficient equations have been derived to calculate the balanceable and/or calculable rates. The method is completely based on matrix algebra (principally different from the graph-theoretical approach), and it is easily implemented into a computer program. (c) 1994 John Wiley & Sons

The authors investigated the rates of conversion to schizophrenia and bipolar disorder after a substance-induced psychosis, as well as risk factors for conversion. All patient information was extracted from the Danish Civil Registration System and the Psychiatric Central Research Register. The study population included all persons who received a diagnosis of substance-induced psychosis between 1994 and 2014 (N=6,788); patients were followed until first occurrence of schizophrenia or bipolar disorder or until death, emigration, or August 2014. The Kaplan-Meier method was used to obtain cumulative probabilities for the conversion from a substance-induced psychosis to schizophrenia or bipolar disorder. Cox proportional hazards regression models were used to calculate hazard ratios for all covariates. Overall, 32.2% (95% CI=29.7-34.9) of patients with a substance-induced psychosis converted to either bipolar or schizophrenia-spectrum disorders. The highest conversion rate was found for cannabis-induced psychosis, with 47.4% (95% CI=42.7-52.3) converting to either schizophrenia or bipolar disorder. Young age was associated with a higher risk of converting to schizophrenia. Self-harm after a substance-induced psychosis was significantly linked to a higher risk of converting to both schizophrenia and bipolar disorder. Half the cases of conversion to schizophrenia occurred within 3.1 years after a substance-induced psychosis, and half the cases of conversion to bipolar disorder occurred within 4.4 years. Substance-induced psychosis is strongly associated with the development of severe mental illness, and a long follow-up period is needed to identify the majority of cases.

The Enhanced Low Dose Rate Sensitivity (ELDRS) in bipolar devices consists of in base current degradation of NPN and PNP transistors increase as the dose rate is decreased. As a result of almost 20-year studying, the some physical models of effect are developed, being described in detail. Accelerated test methods, based on these models use in standards. The conversion model of the effect, that allows to describe the inverse S-shaped excess base current dependence versus dose rate, was proposed. This paper presents the problem of conversion model fitting parameters extraction.

Scaling the energy conversion rate from magnetic field reconnection to different bodies

International Nuclear Information System (INIS)

Mozer, F. S.; Hull, A.

2010-01-01

Magnetic field reconnection is often invoked to explain electromagnetic energy conversion in planetary magnetospheres, stellar coronae, and other astrophysical objects. Because of the huge dynamic range of magnetic fields in these bodies, it is important to understand energy conversion as a function of magnetic field strength and related parameters. It is conjectured theoretically and shown experimentally that the energy conversion rate per unit area in reconnection scales as the cube of an appropriately weighted magnetic field strength divided by the square root of an appropriately weighted density. With this functional dependence, the energy release in flares on the Sun, the large and rapid variation of the magnetic flux in the tail of Mercury, and the apparent absence of reconnection on Jupiter and Saturn, may be understood. Electric fields at the perihelion of the Solar Probe Plus mission may be tens of V/m.

Introducing False EUR and False EUR exchange rates

Science.gov (United States)

Ausloos, M.; Ivanova, K.

2000-10-01

The Euro ( EUR) is a new currency introduced by the European Community. Its exchange rate is very puzzling. We have invented a false Euro ( FEUR) dating back to 1993 and have derived the exchange rates of the FEUR with respect to currencies not belonging to the EUR, i.e., DKK, CHF, JPY and USD. This allows us to search for correlations between the fluctuations preexisting to the introduction of EUR and present ones in such financial data. The detrended fluctuation analysis ( DFA) statistical method is used. This leads to assume a power-law behavior, i.e., a scaling hypothesis, through an exponent α. The latter has demonstrated its usefulness for the investigations of long-range power-law correlations in several types of financial sequences. Our findings show that the α exponent interestingly characterizes fractional Brownian motion of the currency exchange rates between EUR and DKK over a 25 day interval, and usual Brownian motion otherwise and for the three other investigated exchange rates. We can devise an investment strategy based on the localα technique and obtain appreciable gains for the time being.

Modeling and predicting historical volatility in exchange rate markets

Lahmiri, Salim

2017-04-01

Volatility modeling and forecasting of currency exchange rate is an important task in several business risk management tasks; including treasury risk management, derivatives pricing, and portfolio risk evaluation. The purpose of this study is to present a simple and effective approach for predicting historical volatility of currency exchange rate. The approach is based on a limited set of technical indicators as inputs to the artificial neural networks (ANN). To show the effectiveness of the proposed approach, it was applied to forecast US/Canada and US/Euro exchange rates volatilities. The forecasting results show that our simple approach outperformed the conventional GARCH and EGARCH with different distribution assumptions, and also the hybrid GARCH and EGARCH with ANN in terms of mean absolute error, mean of squared errors, and Theil's inequality coefficient. Because of the simplicity and effectiveness of the approach, it is promising for US currency volatility prediction tasks.

The author first analyzes the structure of women's participation patterns in the major foreign currency earning activities in the country, including consideration of their wage levels and the impact of ethnicity, age, educational levels, and skills upon the different components of those activities in which women participate. She then probes the applicability for Sri Lanka of Guy Standing's argument that structural adjustment policies (SAP) have triggered a change in labor force practices leading to a feminization through flexible labor. Many studies have shown that cutbacks in subsidies mandated by SAPs and initiated in the 1980s among developing countries have adversely affected poor women. Women have adjusted to the new situation in a variety of ways, ranging from cutting their household budgets for basic needs to seeking income-generating work in the informal sector and participating in labor-intensive manufacturing activities. In closing, the author assesses the degree to which the new demands made upon women resulting from the effect of SAPs upon their households have stimulated women's increasing participation in foreign currency earning activities.

In an often-cited article in this journal, Caianiello et al. (1982. International Journal of General Systems, 8 (2), 81-92) formulate a 'principle of invariance' for currency systems. They build on this principle to explain the distribution of the coins and banknotes in circulation over the different denominations, and analyse how a currency system adjusts to inflation. This paper shows that Caianiello et al.'s distribution law is flawed because the principle of invariance is false.

Tangible and fungible energy: Hybrid energy market and currency system for total energy management. A Masdar City case study

We propose the introduction of an energy-based parallel currency as a means to ease the transition to energy-conscious living. Abundant fossil energy resources mask the internal and external energy costs for casual energy consumers. This situation is challenging communities that draw a significant fraction of their primary energy consumption from renewable energy sources. The Masdar Energy Credit (MEC) system is a way of translating the fundamental aspects behind energy generation and usage into a tangible reality for all users with built-in fungibility to incentivize collectively sustainable behavior. The energy credit currency (ergo) corresponds with a chosen unit of energy so that the total amount of ergos issued equals the energy supply of the community. Ergos are distributed to users (residents, commercial entities, employees, and visitors) on a subscription basis and can be surrendered in exchange for the energy content of a service. A spot market pricing mechanism is introduced to relate ergos to 'fiat' currency using a continuously variable exchange rate to prevent depletion of the sustainable energy resource. The MEC system is intended to: (i) meet the sustainable energy balance targets of a community (ii) support peak shaving or load shifting goals, and (iii) raise energy awareness.

Short-run Exchange-Rate Dynamics: Theory and Evidence

DEFF Research Database (Denmark)

Carlson, John A.; Dahl, Christian Møller; Osler, Carol L.

Recent research has revealed a wealth of information about the microeconomics of currency markets and thus the determination of exchange rates at short horizons. This information is valuable to us as scientists since, like evidence of macroeconomic regularities, it can provide critical guidance...... of currency markets, it accurately reflects the constraints and objectives faced by the major participants, and it fits key stylized facts concerning returns and order flow. With respect to macroeconomics, the model is consistent with most of the major puzzles that have emerged under floating rates....

Currency Hedging for International Stock Portfolios : A General Approach

This paper tests whether hedging currency risk improves the performance of international stock portfolios. We use a generalized performance measure which allows for investor-dependencies such as different utility functions and the presence of nontraded risks. In addition we show that an auxiliary
