M.Comm. (Financial Economics) / In this study, the equilibrium exchange rate path of the rand/dollar real exchange rate between 1994 and the second quarter of 2011 is estimated. This is done by employing a number of methods, namely, Fundamental Equilibrium Exchange Rates (FEER), Behavioural Equilibrium Exchange Rates (BEER), Natural Real Exchange Rate (NATREX) and the Corbae-Oularis filter method. What stands out in the study is that all of the methods lead to results that are close in proximity, with the Corbae-Oularis method as an exception. In the study it is established that during the period when the ZAR.USD real exchange rate was

Economic intuition suggests that real currency depreciation should lead to long run improvement in a country's trade balance. The short run implications of real depreciation are relatively unknown. The current literature suggests that the short run relationship between trade and real exchange rates is country-specific. This literature has not explored if product and trading partner characteristics play a role in this relationship. This dissertation explores how heterogeneity in trade influences the responsiveness of trade to real exchange rate fluctuations. To my knowledge, this is the first set of papers exploring this heterogeneity. The first paper of this dissertation explores heterogeneity with U.S. commodity-level trade data. Trade responsiveness to real fluctuations varies across product and trading partner characteristics. I find no evidence of long run gains in trade following real depreciation, suggesting that currency manipulation policies meant to improve a country’s trade balance may have no effect on trade in the long run. Prices in international trade contracts with U.S. firms are largely invoiced in U.S. dollars. However, the current literature suggests that the currency in which these prices are set should affect the relationship between trade and real exchange rates in the short run. The second paper of this dissertation explores the implications of currency invoicing patterns using Japanese commodity-level trade data. I find that the response of trade to real fluctuations may differ in the short and long run across product and trading partner characteristics. I also find that the response of trade in the long run may be correlated with comparative advantage. The third paper of this dissertation explores the implications of foreign exchange market liberalization in Japan following the Asian Financial Crisis. I find that liberalization, coupled with financial market reforms, resulted in trade being less responsive to real fluctuations. I also find no evidence of long run trade balance improvement before or after liberalization and that the reform may have eliminated temporary short run gains, suggesting that currency manipulation policies may have no effect on short or long run trade.

[pt] Este trabalho procura discutir alternativas de regimes cambiais, avaliando o comportamento da taxa de câmbio real e seus reflexos no crescimento das exportações dos países emergentes, abrangendo o período das crises cambiais e de balanço de pagamento ocorridas nesses países durante a década de 1990. A flexibilização das restrições à movimentação internacional de capitais além da maior integração nos fluxos de produção e comércio possibilitou às empresas estender suas operações em âmbito global expandindo vendas, desenvolvendo produção, estruturas e compra de insumos nos mais diversos locais. Identificar possíveis correlações entre os regimes cambiais praticados e a evolução das exportações desses países, pode constituir ferramenta útil na avaliação da decisão de investimento multinacional. / [en] The objective of this paper is to discuss alternatives of exchange rate regimes and monetary policy choices, aiming to compare behavior of the real exchange rate with growth of exports, during the period of exchange rate and balance of payments crises during the 1990´s. The international capital movements and greater integration of global production and flexibilization of trade flows, allowed corporations to operate globally, expanding purchasing, production and sales around the world. Identifying possible correlations between the choice of exchange rate regimes and the growth of exports in these countries, can be a practical tool in multinational corporate investment evaluation.

The goal of this study is to search for the January anomaly based on some economic theories and determining factors. By anomaly, we refer to any strange, unusual, or unique occurrence which deviates from established trends or economic principles. These economic theories attempt to explain the equilibrium and disequilibrium in the foreign exchange market. We aim at gauging when the SEK is likely to be misaligned and if an identified anomaly is evidence of a stable and long running phenomenon which an investment strategy could be based on, or whether it is just a short-term unique mispricing which will disappear in the long term. The research questions for this paper include:          What factors account for fluctuations in the Swedish Krona?          Is there evidence of a January effect in the Swedish Krona?   These questions will be evaluated based on the results of our computations on MS excel. Multiple regression analysis will be used to determine the level of significance for the monthly dummy variables. The exchange rates used in this paper include the SEK/€ and the SEK/$.

This thesis is focused on investigating the predictability of exchange rate returns on monthly and daily frequency using models that have been mostly developed in the machine learning field. The forecasting performance of these models will be compared to the Random Walk, which is the benchmark model for financial returns, and the popular autoregressive process. The machine learning models that will be used are Regression trees, Random Forests, Support Vector Regression (SVR), Least Absolute Shrinkage and Selection Operator (LASSO) and Bayesian Additive Regression trees (BART). A characterizing feature of financial returns data is the presence of volatility clustering, i.e. the tendency of persistent periods of low or high variance in the time series. This is in disagreement with the machine learning models which implicitly assume a constant variance. We therefore extend these models with the most widely used model for volatility clustering, the Generalized Autoregressive Conditional Heteroscedasticity (GARCH) process. This allows us to jointly estimate the time varying variance and the parameters of the machine learning using an iterative procedure. These GARCH-extended machine learning models are then applied to make one-step-ahead prediction by recursive estimation that the parameters estimated by this model are also updated with the new information. In order to predict returns, information related to the economic variables and the lagged variable will be used. This study is repeated on three different exchange rate returns: EUR/SEK, EUR/USD and USD/SEK in order to obtain robust results. Our result shows that machine learning models are capable of forecasting exchange returns both on daily and monthly frequency. The results were mixed, however. Overall, it was GARCH-extended SVR that shows great potential for improving the predictive performance of the forecasting of exchange rate returns.
