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 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.

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.

Problem/Relevance: Investigation of exchange rate behaviour has been an important topic in international monetary economics because of the impact of exchange rates on economies. One strand of the literature has focused on explaining the observed movement of the nominal or real exchange rate in terms of macroeconomic variables. Another strand of the literature has evaluated the behaviour of the real exchange rates in relation to the equilibrium exchange rate, which is the real exchange rate that is consistent with macroeconomic balances. Albania implements a free floating exchange rate regime; therefore, evaluating whether the actual real exchange rate is too strong or too weak compared with the real equilibrium exchanges rate has great relevance for the Albanian economy. Research Objective/Questions: Generally, the real exchange rate is defined as the nominal exchange rate adjusted for the relative price differential between domestic and foreign goods and services. So, an appreciation of the nominal exchange rate or higher inflation at home relative to other countries may lead to an appreciation of the real exchange rate. Such appreciation weakens the competitiveness of a country, widens the current account deficit and increases vulnerability to financial crises. The opposite holds true when the real exchange rate depreciates. The aim of this paper is, first, to estimate the equilibrium real exchange rate for the Albanian currency against the euro and, second, to assess the total exchange rate misalignment during the period of 2001Q1-2017Q1. Thus, the equilibrium real exchange rate is used as a benchmark for evaluating the misalignment of the actual real exchange rate. Methodology: This paper explores the determinants of the real exchange rate for Albania, during the period of 2001Q1-2017Q1, based on the stock-flow approach, the so called Behavioural Equilibrium Exchange Rate (BEER), which effectively employs reduced-form modelling of the exchange rate based on standard co-integration techniques. The stock of net foreign assets and productivity changes has been considered fundamental for the real exchange rate. We have used the Johansen co integration technique to test the existence of long-run relationships between our main variables and to evaluate the path of the equilibrium real exchange rate based on vector error correction model (VECM) results. Then the analysis is completed by calculating the degree of misalignment as the difference between the actual real exchange rate and the equilibrium real exchange rate. Major Findings: Based on the Johansen co-integration approach, we find one long-run relationship between the real exchange rate of the Albanian lek against the euro, relative productivity and net foreign assets during the period of 2001Q1 to 2017Q1. The model implies that the real exchange rate is affected, as we expected, by relative productivity and net foreign assets, confirming that an increase in both variables leads to an appreciation of the real exchange rate in the long run. Our results show that the behaviour of the actual real exchange rate is similar to the path of the equilibrium exchange rate and that the degree of misalignment throughout the period is estimated to be moderate. Implications: Our empirical results confirm that the degree of misalignment is reasonable, suggesting a consistency between macroeconomic (especially monetary) policies and the free floating exchange rate regime. Assessing real exchange rate misalignment is a very important issue for policy makers because of the severe welfare and efficiency costs that such misalignment can have for an economy.

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.

PurposeIn this paper, the authors study the long-run determinants of total factor productivity (TFP) in three major European economies over the period 1983–2017, namely Germany, France and Italy.Design/methodology/approachThe authors focus on the capital misallocation effects, scale effects and labor misallocation effects. To this end, the authors study how real interest rate shocks, real exchange rate shocks, real wage shocks and changes in labor regulation affected TFP in major European countries over the last decades. The authors employ a theoretical and an empirical model to investigate the issue. The empirical results are obtained using a VAR model for estimation.FindingsA stripped-down model of labor market in open economy with technology progress allows to identify the relevant variables affecting TFP. On the empirical ground, the authors find a positive relationship between TFP and real interest rate in the long run. Importantly, the authors detect a positive relationship between TFP and real exchange rate. Further, the authors show that the TFP can respond positively to a stricter labor market regulation and to a higher real compensation per employee. The results provide support to the idea that TFP has a positive relation with prices in the long run, while it may be biased along the cycle because of price rigidity.Research limitations/implicationsThe present model is stylized and may not capture all of the details of reality. The analysis should be extended to a larger number of countries. Technology progress could be proxied using different variables, as the R&D expenditure or the number of patents. Micro data, for specific sectors and industries, can improve the quality of the empirical investigation.Practical implicationsMainly the authors find that TFP has a positive relationship with price changes in the long run, while it may be biased along the cycle because of price stickiness. Capital misallocation and labor misallocation can negatively affect TFP. Thus, the observed divergences in European TFP can be traced back to the misallocation effects attributable to the decrease of real interest rate and real wages, together with the raising labor flexibility. Mainly, the authors detect a positive long-run relationship between TFP and real exchange rate. This outcome strengthens the supply-side view of the relationship between productivity and real exchange rate.Social implicationsThe authors believe that the present setup can be helpful to reflect critically on the nodes at the core of the productivity slowdown and asymmetries in the eurozone. The aim is to implement renewed policies in order to favor economic growth, convergence and stability in the euro area.Originality/valueThis research addresses the issue of asymmetries among European economies by focusing on the role played by real prices in the long run. Traditionally, the dynamics of TFP have been attributed only to technological components, human capital and knowledge. This work shows that the dynamics of prices such as the real interest rate, the real exchange rate and the real wage can also influence the technological process by pushing the production system toward choices that are not always optimal for economic growth. An interesting result of this research concerns the positive relationship between real exchange rates and TFP in the long term, evidence of an important supply-side effect on the technological process.
