Real exchange rates have important effects on production, employment and trade, so it is crucial to understand the factors responsible for their variations. This study analyses the main determinants of the real exchange rate and the dynamic adjustment of the real exchange rate following shocks to those determinants, using quarterly South African data covering the period 1975 to 2005. It begins with a review of literature on the determinants of the real exchange rate and provides an updated background on the exchange rate system in South Africa. An empirical model linking the real exchange rate to its theoretical determinants is then specified. In contrast to previous analyses, this study augments the cointegration and vector autoregression (VAR) analysis with impulse response and variance decomposition analyses to provide robust long run effects and short run dynamic effects on the real exchange rate. The variables that have been found to have a long run relationship with the real exchange rate include the terms of trade, real interest rate differential, domestic credit, openness and technological progress. The estimate of the speed of adjustment coefficient found in this study indicates that about a third of the variation in the real exchange rate from its equilibrium level is corrected within a quarter. The impulse response functions broadly corroborate the theoretical predictions, but only the terms of trade, domestic credit and openness have a significant impact on the real exchange rate in the short run. However, only shocks to the terms of trade and domestic credit have persistent effects on the real exchange rate. Results from the variance decompositions are largely similar to those from the impulse response analysis. The terms of trade, domestic credit and openness are the only variables found to significantly explain the variation in the real exchange rate. The most interesting result that emerged from this analysis and is supported by previous research is that among other determinants, the terms of trade explain the largest proportion of the variation in the real exchange. On balance, the evidence therefore suggests that real exchange rate fluctuations are predominantly equilibrium responses to real and monetary shocks rather than fiscal policy shocks.

Exchange rates are one of the most essential determinants of a country's economic performance in terms of level of trade. Since the exchange rate is one of the best indicators of competitiveness, this study sought to examine the behaviour of the rand against other emerging countries in the South African exchange market. The study explored the trends and estimated the forecasting accuracy of six currency markets using ARCH-family and Random walk models over the period 1994 to 2013.The six currency markets examined were the Rand/Dollar, Rand/Pound, Rand/Euro, Rand/Yen and Rand/Pula. The Rand exchange rates did exhibit the characteristics of volatility clustering and asymmetric effects suggesting volatility of the Rand. Exchange rates tend to rise when there is more bad news in the financial market than good news and positive shocks imply a higher next period conditional variance than negative shocks of the same sign.

The study examines exchange rate volatility and inflation in South Africa over the period of 1987- 2012 using annual data. With the use of VAR, ADF unit root testing and Johansen for cointegration the study examines the relationship between exchange rate volatility and inflation in South Africa. The study also examines other variables, which are Money Supply, Trade Openness, Real Interest Rate and Real Gross Domestic Product (RGDP), if they had an impact on inflation and had contributed significantly to inflation during the period under review. All macroeconomic variables were identified to have an impact on inflation in the long-run. Exchange rate volatility was identified as the main variable that had substantial impact on inflation rate. The study recommended the current system used by the authorities was working well, as they can pursue a countercyclical macro policy, but also continue to manage the float by intervening to stabilize the exchange rate. The reason for this recommendation was that because one of the advantages of floating exchange rate is freeing internal policy, with a floating exchange rate, balance of payments disequilibrium would be rectified by a change in the external price of the currency. However, with a fixed rate, curing a deficit could involve a general deflationary policy resulting in unpleasant consequences for the whole economy such as unemployment.

The effect of real exchange rate volatility on export performance: evidence from South Africa (2000-2011) This study sought to investigate the relationship between exchange rate volatility and export performance in South Africa. The main objective of the study was to examine the impact of exchange rate volatility on export performance in South Africa. This relationship was examined using GARCH methods. Exports were regressed against real effective exchange rate, trade openness and capacity utilisation. The research aimed to establish whether exchange rate volatility impacts negatively on export performance in the manner suggested by the econometric model. The result obtained showed that exchange rate volatility had a significantly negative effect on South African exports in the period 2000-2011.

The goal of this diploma thesis is to assess the suitability and readiness of the Slovak Republic to adopt a single European currency. In analyzing the costs and benefits relating to Slovakia?s accession to the EMU, this thesis is guided by the theory of the OCA. The thesis provides a survey of the OCA theory, attempts to measure some of the OCA indicators and calculate OCA index for Slovakia. The results suggest that Slovakia fulfils the necessary condition for joining the monetary union, i.e. it is relatively well aligned with the euro area. The diploma thesis concludes that Slovakia is relatively suitable and well-prepared to join the euro area in 2009.

The thesis explains the theory of purchasing power parity and related concepts. It shows differences in prices and wages all around the globe and gives theoretical explanation of existing disparities. The goal is to find out how prices differ in reality, where costs of living are the highest or the lowest and what makes some products more or less expensive in different countries. In order to answer the questions the thesis deals with, the variety of sources was used, starting from economics textbooks, academic journals, literature reviews, the Economist website, a study of UBS 'Prices and Earnings', International Monetary Fund database and others.

There are two key observations in international macroeconomics which pertain to output and real exchange rate dynamics. First, fluctuations in national output around its long-run growth path are very persistent. Second, fluctuations in real exchange rates are very persistent. The sticky price framework offers an explanation for both phenomena. The first and second essay of this thesis take an empirical approach to test the predictions of this framework. In the first essay I test the prediction of the sticky price model for output dynamics using annual IFS data on 51 countries over the period 1950 -1996. The model predicts that price stickiness should be less important in high inflation countries and therefore output fluctuations less persistent. I find that, this inverse relationship is statistically insignificant in the international data. A similar result holds for OECD countries. In the empirical implementation I explicitly control for the within-country time variation in inflation by first characterizing the inflationary environment using the long-run movements in inflation (trend inflation), and secondly, by excluding episodes of hyperinflation. The analysis shows that when the within-country time variation in inflation is ignored, there is support for the prediction. For instance, the inverse relationship between persistence in deviations of output from its long-run growth path and average inflation is statistically significant in the full sample. However, the exclusion of a few episodes of hyperinflation renders this relationship statistically insignificant. In the second essay I investigate the prediction of the sticky price model for real exchange rate dynamics using annual IFS data on 49 countries over the period 1972-1996. The model predicts that deviations of real exchange rates from purchasing power parity should be less persistent, in high inflation countries. The empirical analysis reveals that the support for such an inverse relationship is extremely fragile. In particular, eliminating episodes of hyperinflation renders this relationship statistically insignificant. The lack of evidence in favour of the two predictions of the sticky price model is problematic since this model is extensively used as a microfoundation for understanding output and real exchange rate fluctuations. In the third essay I take a structural approach to qualitatively explore the role of slow diffusion of new products in propagating the effect of technology shocks on output. I present a multi-sector dynamic general equilibrium model in which the creation of new products requires real resources. These products are beneficial for the economy but only upon complete diffusion. However, this diffusion is not instantaneous. I find that relative to a model in which there is instantaneous diffusion of new products, the qualitative output dynamics are similar to what is observed in the U.S. data. This warrants further quantitative investigation. / Arts, Faculty of / Vancouver School of Economics / Graduate

This thesis analyzes the effect of corporate tax rates on the purchasing-power-parity (PPP) doctrine. The data used to test this hypothesis are drawn from the U. S., the U. K., the Federal Republic of Germany, Canada, and Japan. The first chapter introduces the reader to the concepts of the PPP doctrine and states the hypothesis. Chapter 2 reviews the literature on the PPP doctrine. Chapter 3 specifies a model of the PPP doctrine including tax rates. Chapter 4 reports and interprets the findings. The study is summarized and conclusions are drawn in chapter 5. In this study it is shown that tax rates are significant only in the case of the U. S. dollar/Canadian dollar exchange rate.

[pt] Esse trabalho estima a transmissão da variação da taxa de câmbio nominal para o índice de preços oficial brasileiro, seus subgrupos e subitens. Os resultados apontam que flutuações do pass-through do câmbio para a inflação podem ser explicados pelo hiato do produto e pelo desvio das expectativas de inflação em relação à meta, entretanto, o repasse se mostrou maior em períodos de depreciação cambial se comparados a períodos de apreciação. Adicionalmente, encontramos não-linearidade do pass-through, uma vez que esse se amplifica no caso de variações acima de 10 por cento. / [en] This thesis estimates the transmission from the nominal exchange rate to Brazilian official consumer price index and its groups and items. The results point that fluctuations of pass-through from exchange rate to inflation could be explained by the output gap and the inflation expectations deviation from its central target. Although, the pass-through is more significant when in a nominal exchange rate depreciation period than appreciation period. Additionally, there is a conclusion that the pass-through is non-linear, because it is more significant when exchange rate variation exceeds 10 percent.
