Opis:
The focus of this study was on investigating the response of tobacco exports to real exchange rates and real exchange rate volatility and other factors in Zimbabwe using secondary data spanning from 1980 to 2019. Bilateral nominal exchange rates and time-variant weights of Zimbabwe’s 10 major trading partners were calculated and used to compute the real exchange rate index. The time-dependent weighting system was used to better represent the evolution of trade patterns in the index. The arithmetic method was employed for computing the index. Generalized autoregressive conditional heteroskedasticity (GARCH) and autoregressive conditional heteroscedasticity (ARCH) models were used to generate the real exchange rate volatility index. The export response function was adopted as the tobacco exports response model. The variables in the tobacco exports response model were the realworld Gross Domestic Product (GDP), real exchange rate, terms of trade, real exchange rate volatility and dollarization. A vector error correction model (VECM) was used to estimate the response of tobacco exports to real exchange rate, real exchange rate volatility and other factors. The VECM results indicated that real world GDP was insignificant in both the short and long run. In the long run, the real exchange rate appreciation had a negative impact on tobacco exports. Conversely, in the short run, the depreciation of real exchange rate had a positive impact on tobacco exports. Hence, the government has to adopt other mechanisms that reduce uncertain movements of exchange rates.

The aim of the paper is to present an example of analysis of exchange rate behavior with use of tools, built in GRETL econometric package, which have been developed by researchers often with background in physics or similar fields, but some (such as tests of integration and cointegration) are less known to physical audience. The series of interest is a bilateral USDPLN exchange rate; including the corresponding stock indices as additional variables can improve quality of a model even in period of crisis.

Opis:
We propose two novel methodological approaches - the detrending moving average based regression coefficient estimator and the scale-dependent instrumental variable estimator - and show their utility on a specific case of dependence between stock markets and connected foreign exchange rates in the Central European region - the Czech Republic, Hungary, and Poland. The methodology has proven useful as we uncovered several interesting findings such as scale dependence of the shock transmission and differences between the Euro and U.S. dollar currency pairs. The Polish currency is also the most sensitive of the three with respect to the stock market shocks. The proposed methodology can be applied to any system with potential endogeneity issues if one is interested in the scale variability of the effect of interest.

Opis:
Our objective has been to measure an impact of the two main global currencies - Euro and USD on shaping of exchange rates in countries of Central Europe. We have also endeavored to measure whether and to what extent a different approach to the Euro introduction as well as differentiated macroeconomic situation of these countries influenced the behavior of their exchange rates. The hitherto analyses indicate that the PLN rate of exchange was until 2004 strongly tied to the USD, but since 2004 links with the EUR exchange rate have become stronger. However the exchange rates of other countries in the region had been tied to the EUR earlier than the PLN exchange rate as they already had strong such links in the whole period of our analysis. Currency integration of the Central European countries is very strong although they are formally outside the euro zone and formation of their exchange rates should be perceived through trends of the EUR exchange rate versus other currencies, the USD.

Opis:
The aim of the paper is to examine the relation between foreign exchange rates and interest rate differentials in Poland, the Czech Republic, and Hungary. The exchange rate equations are inspired by the uncovered interest rate parity (i.e. the UIP condition). The results of empirical studies are usually contrary to the UIP condition. One of the explanations of this puzzle is the existence of certain nonlinearities. The nonlinearities appear because of transaction costs, central bank interventions, limits of speculations, hysteresis, or changes in risk perception. I estimate smooth transition autoregressive models. The threshold variable is an interest rate differential or a level of economic activity. I examine the exchange rates of USD and EUR and 1-, 3- and 6- months and 5- years interest rates. I also test various proxies for risk premium.

Opis:
Kurs walutowy jest jedną z ważniejszych cen w otwartej gospodarce. Z praktycznych i teoretycznych powodów bardzo użytecznym jest zbadanie jego poziomu równowagowego. Istnieje bardzo wiele teorii wyjaśniających kształtowanie się kursu walutowego. W artykule przedstawiono determinanty kursu walutowego, wynikające zarówno z teorii monetarystycznej, jak i teorii bilansu płatniczego. Następnie, na ich podstawie oraz przyjmując różne definicje równowagi, zbudowano predyktory nominalnego kursu PLN/USD oraz obliczono jego równowagowe poziomy. Przeprowadzona analiza empiryczna wykazała, że niezależnie od przyjętej definicji stanu równowagi otrzymane trajektorie poziomu kursów równowagi nie różnią się od siebie istotnie oraz są zbliżone do rzeczywistego kształtowania się kursu PLN/USD w okresie 1995-2003.
Exchange rate is one of the most important prices in an open economy. For theoretical and practical reasons it is useful to calculate an equilibrium level of exchange rate. There is a wide range of theories explaining exchange rate determinants. This article presents determinants of exchange rates derived from monetary theory and balance of payments theory. Upon these fundamental economic theories and defining different definitions of equilibrium we have calculated predictors of nominal exchange rate of PLN against USD. We have also computed equilibrium level of this exchange rate. Empirical results have shown that the theoretical equilibrium values do not statistically significantly differ on the method used in equilibrium computations and they are similar to the empirical trajectory of PLN/USD in the period 1995-2003.

Opis:
We test whether the floating exchange rates of the EU New Member States against the euro are determined jointly within the panel VEC framework. We find that the exchange rates of the Czech koruna, the Polish zloty and the Hungarian forint follow the same long-run relationship, in which the real exchange rates are explained by the real interest rates parities and the spreads of the credit default risk premiums. In case of the Romanian leu, the common relationship is rejected, which is likely due to differences in the economic setting. The results confirm that the currency markets of these three countries are closely related, since the appreciation/depreciation of one currency leads to similar movements in the other currencies of the NMS. The estimated misalignments exhibit some common patterns in terms of time spans and percentage values of under/overvaluation.

Opis:
Aim/purpose - The aim of this paper is to present two cases of crises in Greece and Italy and to evaluate the shadow exchange rates of hypothetical new currencies (re)introduced after Grexit and Italexit. Design/methodology/approach - Both shadow exchange rates are estimated using speculative pressure index concept that emphasizes the importance of changes in foreign exchange reserves and interest rate differentials in the absence of an independent nominal exchange rate. The research sample covers Greece in 1989-2020 and Italy in 1989-2020. Findings - The research presented the estimation of shadow exchange rates EUR/GRD and EUR/ITL during the euro zone membership period. Leaving the euro area one can expect the following market rates: EUR/GRD 600 and EUR/ITL 1850. That would mean 75% depreciation and 5% appreciation to the current euro parities EUR/GRD 340.75, and EUR/ITL 1936.27, respectively. Research implications/limitations - After potential Grexit Greek authorities could expect significant nominal depreciation of a new currency (or should introduce it with a substantial discount). In the case of Italexit, the new currency would preserve its nominal value. The limitations of the research methodology are: a long period of the analysis covers structural changes of financial markets, crisis events, political factors (e.g., QE programs). Originality/value/contribution - The originality of this approach lies in the combination of two important economic concepts - the idea of shadow exchange rate and the index of speculative pressure. Combined together they help to prepare the methodology of shadow exchange rates evaluation for currencies that are currently in the common currency system (e.g., currency union). These results can help in economic and political discussions on effects of leaving the currency union.

Opis:
Aim/purpose – The aim of this article is to present two cases of exchange rate controls in Switzerland and Argentina. The paper also examines the problem of presence and evaluation of shadow exchange rate in both countries. Design/methodology/approach – The shadow exchange rates are estimated using speculative pressure index concept that emphasizes the importance of not only exchange rate movements but also changes in foreign exchange reserves as well as interest rate differentials. The research sample covers Switzerland 2001-2016 and Argentina 2006-2016 (for shadow exchange rate simulation: 2011-2014 and 2011-2015, respectively). Findings – The conclusions drawn from international experience and conducted empirical analysis are positive. In both cases, shadow exchange rates were close to market rates after the removal of controls. During the restrictions periods shadow rates followed the intuition given by speculative pressure index concept (and by monetary approach, simultaneously). Research implications/limitations – The research suggests that market forces in both countries were still able to restore exchange rates to market values after the period of control. However, it is obvious that it is very difficult to prove that shadow rates were always determined by economical forces and close to their long-term equilibrium values. Originality/value/contribution – The original approach combines two important economic concepts – the idea of shadow exchange rate and the methodology of index of speculative pressure. Combined together they can help to analyze two interesting and relatively new cases of foreign exchange controls in Switzerland and Argentina. The results can be valuable for economists, researchers and politicians who support or reject the idea of controlling macroeconomic parameters in modern, open economy.

This study aims at investigating the link between international oil prices and the exchange rate in case of a small open industrial economy without oil resources such as Poland. The results of Granger-causality test show that the null hypotheses of Zloty-US dollar exchange rate does not granger cause rejection of Oil Price is not rejected while there exists reverse causality in 3 and 4 year lags at 5% and 10% levels. Therefore, we conclude that increases in oil prices have had a positive impact on the exchange rates over the period between 1982:12 and 2006:05.

The paper provides a short description of barrier options together with an analysis of their performance compared to the performance of standard options and structured time deposits that incorporate the element of barrier in their construction. The results obtained show that some of considered structured time deposits linked to the foreign exchange rates and standard options could bring some profits unlike the majority of coressponding barrier options. The disadavantage of barrier options is they can stay inactive or a “spike” in the underlying asset price can cause the option to be knocked-out.

Analiza korelacji warunkowych między zwrotami kursów walutowych daje nam istotną informację na temat współzależności pomiędzy rynkami walutowymi. W niniejszym artykule opisujemy ten rodzaj zależności w przypadku rynków walutowych w krajach Europy Centralnej, posługując się modelem dynamicznych korelacji warunkowych (DCC), wprowadzonym przez Engle’a. Badamy zmiany w poziomie korelacji warunkowych między kursami analizowanych walut względem euro i dolara amerykańskiego, w okresach stabilności rynków i w okresach kryzysów. Uzyskane wyniki wskazują, że analizowane kursy walutowe podążają za odpowiadającymi kursami euro. Otrzymujemy również pewne wyniki dotyczące efektu zarażania pomiędzy rozważanymi rynkami.
The analysis of conditional correlations between returns of foreign exchange rates gives us significant information about co-movement between different currency markets. In the paper, we model this kind of dependency in the case of currency markets in Central European countries using Engle’s DCC models. We investigate the changes in the level of conditional correlations during stability and crisis periods. In this context we try to find the evidence of the contagion effect in the considered region.

Opis:
This paper presents a data mining approach to forecasting exchange rates. It is assumed that exchange rates are determined by both fundamental and technical factors. The balance of fundamental and technical factors varies for each exchange rate and frequency. It is difficult for forecasters to establish the relative relevance of different kinds of factors given this mixture; therefore the utilization of data mining algorithms is advantageous. The approach applied uses a genetic algorithm and neural networks. Out-of-sample forecasting results are illustrated for five exchange rates on different frequencies and it is shown that data mining is able to produce forecasts that perform well.
W artykule przedstawiono proces eksploracji danych statystycznych w prognozowaniu kursów walutowych. Zakładamy, że kursy walutowe pozostają pod wpływem zarówno czynników o charakterze fundamentalnym, jak i czynników pozaekonomicznych. Równowaga pomiędzy tymi czynnikami różni się w zależności od rodzaju kursu walutowego i częstotliwości jego pomiaru. Prognostykom trudno jest ustalić względną siłę wpływu różnych czynników, stąd analiza polegająca na eksploracji danych ma określone zalety. W proponowanym podejściu wykorzystano algorytmy genetyczne i sztuczne sieci neuronowe. Przedstawiliśmy wyniki eksperymentów prognostycznych poza próbą statystyczną w odniesieniu do pięciu kursów walutowych, obserwowanych z różną częstotliwością. Pokazaliśmy, że metoda eksploracji danych może stanowić skuteczne narzędzie prognostyczne.

modelling of currency exchange rates
Opis:
An exchange rate can be expressed in the form of a binary-temporal representation. Such a representation is based on a discretization of movements in the exchange rate, in which to each change in the value - equal to a given discretization unit – two parameters are allocated: a binary value, consistent with the direction of change in the exchange rate (increase 1, decrease 0) and duration. Statistical examination proves the existence of dependencies between the parameters of previous changes and the direction of future changes. To model the exchange rate using the applied binary-temporal representation, an appropriate model was developed that enables estimation of the probability of the direction of future changes in the currency exchange rate based on the parameters of historical changes. This article presents an analysis of the influence of the chosen discretization unit on the quality of exchange rate modelling. For this purpose, software was written in MQL4 and C++. As a result of the study, an optimal value for the discretization unit and the optimal parameters of the model providing the highest efficiency were determined. The input data used in the analysis involved tick data for the AUD/NZD exchange rate for a five-year time frame 2012–2017.
