The aim of this paper is to determine the relationship between the exchange rate (nominal and real) and foreign exchange reserves based on monthly data for the period from September 2006 to April 2019, using unit root tests and cointegration tests that take into account the possibility of structural break existence. The results of the causality test indicate that there is a long-term relationship between the nominal exchange rate and foreign exchange reserves. On the other hand, the existence of a long-term relationship between the real exchange rate and the foreign exchange reserves has not been confirmed, but there is a short-term causality, that is, the real exchange rate Granger-causes foreign exchange reserves.

The aim of this paper is to discuss the trend of overvaluation of the Brazilian currency in the 2000s, presenting an econometric model to estimate the real exchange rate (RER) and which should be a reference level of the RER to guide long-term economic policy. In the econometric model, we consider long-term structural and short-term components, both of which may be responsible for explaining overvaluation trend of the Brazilian currency. Our econometric exercise confirms that the Brazilian currency had been persistently overvalued throughout almost all of the period under analysis, and we suggest that the long-term reference level of the real exchange rate was reached in 2004. In July 2014, the average nominal exchange rate should have been around 2.90 Brazilian reais per dollar (against an observed nominal rate of 2.22 Brazilian reais per dollar) to achieve the 2004 real reference level (average of the year). That is, according to our estimates, in July 2014 the Brazilian real was overvalued at 30.6 per cent in real terms relative to the reference level. Based on these findings we conclude the paper suggesting a mix of policy instruments that should have been used in order to reverse the overvaluation trend of the Brazilian real exchange rate, including a target for reaching a real exchange rate in the medium and the long-run which would favor resource allocation toward more technological intensive sectors.

This study provides new evidence showing that the real exchange rate (RER) does not play an important role in the growth of Mexican GDP. Economic growth is not an automatically predetermined result of relative price correction, and it is important to consider distinctive aspects of national institutional arrangements (fiscal and monetary, for example) for understanding theoretical causality of demand. The empirical results show public expenditure is an overlooked variable in regressions where the exchange rate affects product growth. After incorporating public expenditure, the RER impact on growth becomes insignificant. For its part, public expenditure has a positive and significant effect on GDP in the long term. The RER does not lead to greater GDP since exports are not stimulated through price.

This article calculates the equilibrium real exchange rate for the UK economy. The long-run trade and supply side relationships from HM Treasury's model are used to estimate the level of the real exchange rate consistent with the UK economy growing at its ‘natural’ rate while achieving a sustainable current account position. The model shows that the real exchange rate associated with macroeconomic equilibrium lies well below the actual rate for most of the 1990s. This result has important implications for possible UK participation in the single European currency as, once the nominal exchange rate is fixed, overvaluation can only be corrected by holding UK inflation lower than that elsewhere. Achieving this may be costly in terms of jobs and output.

Real exchange rate has direct effects on trade particularly on international trade and has indirect effects on productions and employments, so it is crucial to understand the factors which determine its 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 yearly Ethiopian time series data covering the period 1971 to 2010. It begins with a review of literatures on Exchange rate, real exchange rate, determinants of the real exchange rate and provides an updated background on the exchange rate system in Ethiopia. An empirical model linking the real exchange rate to its theoretical determinants is then specified. This study had employed 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. Share of investment, foreign exchange reserve, capital inflow and government consumption of non-tradable goods were the variable that have been found to have a long run relationship with the real exchange rate. 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 year. The regression result of VECM reveals that terms of trade, nominal exchange rate, and one period lag of capital flow were the variables significantly affects the real exchange rate in the short run. However, the impulse response and variance decomposition analysis shows a better picture of the short run dynamics. The their analysis provided evidence that the Shocks to terms of trade, nominal exchange rate, capital inflow and share of investment have persistent effects on the real exchange rate in the short run. In general the regression results of both long run and short run models mostly suggest that the fluctuations of real exchange rates are predominantly responses to monetary policies shocks rather than fiscal policy shocks.

Indonesia's economy refers to an open economy. In conducting international trade, countries must compare their currencies with currencies belonging to other countries. Where, the United States currency, namely the dollar, is still the standard of world exchange rates and is used in international transactions. The effect of fluctuations in the exchange rate of the rupiah with the dollar is the occurrence of depreciation or appreciation which will affect Indonesia's economic activities. The purpose of this study is to determine the effect of inflation, the money supply (M2), the SBI interest rate, and foreign exchange reserves on the rupiah exchange rate in the short and long term. The variables that are thought to be able to influence changes in the rupiah exchange rate are the inflation rate, the money supply (M2), the SBI interest rate, and foreign exchange reserves. This research was conducted during January 2017 to December 2020, using the Error Correction Model (ECM). The result is a long-term and short-term relationship. In the short term, foreign exchange reserves and the money supply (M2) significantly affect the exchange rate. Meanwhile, in the long term, the SBI interest rate, money supply (M2), and foreign exchange reserves significantly affect the exchange rate.

The idea that prices and exchange rates adjust so as to equalize the common-currency price of identical bundles of goods—purchasing power parity (PPP)—is a topic of central importance in international finance. If PPP holds continuously, then nominal exchange rate changes do not influence trade flows. If PPP does not hold in the short run, but does in the long run, then monetary factors can affect the real exchange rate only temporarily. Substantial evidence has accumulated—with the advent of new statistical tests, alternative data sets, and longer spans of data—that purchasing power parity does not typically hold in the short run. One reason why PPP doesn’t hold in the short run might be due to sticky prices, in combination with other factors, such as trade barriers. The evidence is mixed for the longer run. Variations in the real exchange rate in the longer run can also be driven by shocks to demand, arising from changes in government spending, the terms of trade, as well as wealth and debt stocks. At time horizon of decades, trend movements in the real exchange rate—that is, systematically trending deviations in PPP—could be due to the presence of nontraded goods, combined with real factors such as differentials in productivity growth. The well-known positive association between the price level and income levels—also known as the “Penn Effect”—is consistent with this channel. Whether PPP holds then depends on the time period, the time horizon, and the currencies examined.

The main focus of this paper is to examine the impact of the real effective exchange rate on economic growth in Sierra Leone. First an analytical framework is developed to identify the determinants of the real effective exchange rate. Using quarterly data and employing recent econometric techniques, the relationship between the real effective exchange rate and economic growth is then investigated. A bivariate Granger causality test was also employed as part of the methodology to examine the causal relationship between the real exchange rate and economic growth. The empirical results suggest that the real effective exchange rate correlates positively with economic growth, with a statistically significant coefficient. The results also indicate that monetary policy is relatively more effective than fiscal policy in the long run, and evidence of the real effective exchange rate causing economic growth was profound. In addition, the results showed that terms of trade, exchange rate devaluation, investment to GDP ratio and an excessive supply of domestic credit were the main determinants of the real exchange rate in Sierra Leone.
