Magister Scientiae - MSc / This project "An application of multiple regression in exchange rate arrangement" focused on the processes followed by different countries when choosing an exchange rate regime for currency stabilization. It analyses the consequences faced by emerging markets as a result of changes in volatility of developed countries’ currencies (American Dollar, Japanese Yen, EURO, British Pound and the Canadian Dollar). / South Africa

Exchange rate economics has achieved substantial development in the past few decades. Despite extensive research, a large number of unresolved problems remain in the exchange rate debate. This dissertation studied three puzzling issues aiming to improve our understanding of exchange rate behavior. Chapter Two used advanced econometric techniques to model and forecast exchange rate dynamics. Chapter Three and Chapter Four studied issues related to exchange rates using the theory of New Open Economy Macroeconomics. Chapter Two empirically examined the short-run forecastability of nominal exchange rates. It analyzed important empirical regularities in daily exchange rates. Through a series of hypothesis tests, a best-fitting fractionally integrated GARCH model with skewed student-t error distribution was identified. The forecasting performance of the model was compared with that of a random walk model. Results supported the contention that nominal exchange rates seem to be unpredictable over the short run in the sense that the best-fitting model cannot beat the random walk model in forecasting exchange rate movements. Chapter Three assessed the ability of dynamic general-equilibrium sticky-price monetary models to generate volatile foreign exchange risk premia. It developed a tractable two-country model where agents face a cash-in-advance constraint and set prices to the local market; the exogenous money supply process exhibits time-varying volatility. The model yielded approximate closed form solutions for risk premia and real exchange rates. Numerical results provided quantitative evidence that volatile risk premia can endogenously arise in a new open economy macroeconomic model. Thus, the model had potential to rationalize the Uncovered Interest Parity Puzzle. Chapter Four sought to resolve the consumption-real exchange rate anomaly, which refers to the inability of most international macro models to generate negative cross-correlations between real exchange rates and relative consumption across two countries as observed in the data. While maintaining the assumption of complete asset markets, this chapter introduced endogenously segmented asset markets into a dynamic sticky-price monetary model. Simulation results showed that such a model could replicate the stylized fact that real exchange rates tend to move in an opposite direction with respect to relative consumption.

This diploma paper describes the process of managing of exchange rate risk in an export company. At the beginning of the work there is short overview of the basic concepts of the exchange rate theory. The next part is focused on the determination of the exchange rate and on the basic methods of exchange rate prediction -- fundamental, technical and psychological analyses. These chapters are followed by the next steps in the process of the exchange rate risk managing with a view to the analyses of the firm's exchange exposition (especially to its quantification) and to instruments used to exchange rate hedging (especially to currency derivatives). In the end of the diploma paper there is a brief summary of development of the financial crises 2008/09 with reference to its influence on the exchange rate of the Czech crown to Euro.

The thesis is focused on exchange rate policy of the Czech Republic. Its goal is to analyze this policy in connection with reaching an external balance of the economy and also from the point of view of its role during transformation in the Czech Republic. The common European currency and its possible introduction in the Czech Republic is also an issue associated with the exchange rate policy. At the beginning, basic terms and related theoretical approaches are introduced and in the next part, balance of payments approaches are analyzed using selected examples. The following chapter deals with exchange rate policy transformation process in Czechoslovakia and then in the Czech Republic. The last part is aimed at European monetary integration and especially at potential Czech accession to the euro area.

In the first part thesis describes theoretical basis about international business and exchange rate risk. The practical part focuses on analysis of the company through analysis of competition, financial analysis and SWOT analysis. Integrated overview is supplemented by exchange rate risk analysis. In the last part of thesis there are specific options of elimination exchange rate risk.

Denna studie syftar till att undersöka om växelkursen har en påverkan på svensk varuexport och om effekten skiljer sig med avseende på varugrupp. För att uppnå syftet används en ARDL-Approach som skattas med hjälp av tidsseriedata från 32 viktiga handelspartners och 10 viktiga varugrupper under perioden januari 1995 till december 2019. Två effekter är i fokus: effekten av en real appreciering/depreciering och effekten av en volatil växelkurs. För den totala varuexporten visas signifikanta resultat för att en depreciering av den svenska kronan med 1 % i genomsnitt ökar varuexporten med 0,192 % på kort sikt och med 0,416 % på lång sikt. Effekten av en volatilitetsökning på 1 % skattas till -0,366 % på kort sikt och till -0,794 % på lång sikt, dock utan statistisk signifikans. På varugruppsnivå tyder resultaten på att olika varor påverkas olika av förändringar i växelkursen. / The aim of this study is to examine whether the exchange rate has an impact on Swedish export of goods and if this effect differs between different categories of goods. To reach the aim, we use an ARDL-Approach with time-series data from 32 important trade partners and 10 different categories of goods during the period January 1995 to December 2019. Two effects are in focus: The effect of real appreciation/depreciation and the effect of exchange rate volatility. In total export of goods, this study finds significant results that a 1 % depreciation of the Swedish crown on average increases exports of goods with 0,192 % in the short-term and with 0,416 % in the long-term. The effect of an increase in exchange rate volatility by 1 % is estimated to decrease the exports of goods with -0,366 % in the short run and -0,794 % in the long run, but without statistical significance. The results imply that different categories of goods are being affected differently by changes in the exchange rate.

Do renminbi (RMB) exchange rate fluctuations affect cross-border M&A activities of enterprises at the micro level? This paper centers on this major issue, and we study and analyze the impacts of RMB internationalization on the magnitude and success of cross-border M&As. We investigate the impacts of exchange rate changes on the magnitude and success of enterprise-level cross-border M&As by developing nominal exchange rate (NER) and real exchange rate (RER) volatility indicators using data from the Thomson Financial SDC Platinum Merger and Acquisitions database. By applying a variety of indicators and subsample estimates in the study, we find that exchange rate volatility (of either NER or RER) is significantly negatively correlated with enterprise-level cross-border M&As, suggesting that RMB exchange rate movements deter cross-border M&As to some extent; fluctuations in RMB exchange rate have a significant negative impact on the success of cross-border M&As, and the exchange rate risk induced by exchange rate changes increases the risk of cross-border M&As; meanwhile, exchange rate fluctuations have a significant inhibitory effect on conglomerate M&As in addition to horizontal cross-border M&As. In addition, exchange rate fluctuations have a significant inhibitory effect on the profit-oriented cross-border M&As of enterprises in non-state-owned-or-controlled industries. Therefore, we should take prudent actions to prevent the impacts of RMB exchange rate movements on cross-border M&As, actively tap the potential of bilateral investment treaties in securing cross-border M&As, promote coordination between RMB exchange rate regulation iimechanisms and the “go global” strategy, and improve the level of internationalization and competitiveness of Chinese enterprises. / Business Administration/Finance

The thesis focuses on the question of undervaluation of the renminbi exchange rate to the U.S. dollar from the perspective of three selected alternative methods of calculating long term equilibrium exchange rate. In the case of calculations of behavioral equilibrium exchange rate and the natural real exchange rate, I performed calculations by using vector error correction model. In the case of fundamental equilibrium exchange rate I used error correction model. The input data used in the models are ranging from 1980 to 2010. Those are primarily value of nominal exchange rates, price levels and foreign trade. According to my results behavioural and fundamental equilibirum exchange rate show undervaluation of the renminbi to the year 2010, while the natural real exchange rate indicates a slight overvaluation of the renminbi to the year 2010.

This research analyzes the Brazilian exchange rate system and the exchange rate interventions after flexible exchange rate system implementation in 1999, and have like base the "fear of floating" approach, the exchange rate interventions theory and of the fact exchange rate classification. The evidences found for Brazil suggest that the exchange rate interventions illustrate objectives of the exchange rate debt reduction and do not follow the "fear of floating objectives". In the others empirical tests find a weak short run relation between exchange rate and domestic interest rate, exchange rate backups, domestic inflation and public debt in proportion to the GDP, and a strong short run relation between exchange rate and country risk, indicating that the movements of the exchange rate do not affect heavy the variables of the "fear of floating" and that do not believe that the country suffer from that problem. Confirming that idea, finds that of the fact exchange rate system is compatible with the jure exchange rate system, despite it find low exchange rate flexibility. / Esta pesquisa analisa o sistema cambial brasileiro e as intervenções cambiais após a implementação do sistema cambial flexível em 1999 e tem como base a abordagem do medo de flutuar , a teoria de intervenções cambiais e a classificação de sistemas cambiais de facto. As evidências encontradas para o Brasil sugerem que as intervenções cambiais ilustram objetivos de redução da dívida cambial e não seguem os objetivos da abordagem do medo de flutuar . Em outros testes empíricos encontra-se uma fraca relação de curto prazo entre taxa de câmbio e taxa de juros domésticos, reservas cambiais, inflação doméstica e dívida pública em proporção ao PIB, e uma forte relação de curto prazo entre taxa de câmbio e risco país, indicando que os movimentos da taxa de câmbio não afetam pesadamente as variáveis da abordagem do medo de flutuar e que, portanto, não há razões para crer que o país sofra desse problema. Confirmando essa idéia, encontra-se que o sistema cambial de facto é compatível com o sistema cambial de jure, apesar de encontrar-se uma baixa flexibilidade cambial. / Mestre em Economia
