Explaining Real Exchange Rates Fluctuations

This paper attempts to explain the sources of real exchange rate fluctuations for a set of advanced economies and Central and Eastern European transition economies. To address this, firstly, we compute two measures of the share of the variance in the real exchange rate accounting for movements in the relative prices of traded goods between countries. Secondly, we estimate structural (identified) vector autoregression (SVAR) models, and decompose real and nominal exchange rate movements into those caused by real and nominal shocks. Thirdly, we complete the previous steps with an impulse-response analysis. The results suggest that: (1) for transition economies, under regimes of managed nominal exchange rates, the relative price of non-traded goods explains a large percentage of the variance in the real exchange rate; (2) there is evidence of instability in the variance decomposition of real exchange rates for advanced economies across samples; and (3) as result of diverse fiscal and monetary policies in transition economies, real exchange rates in some economies are driven mostly by real shocks while in others they are driven mostly by nominal shocks.real exchange rate, nominal exchange rate, real shocks, nominal shocks, SVAR models, advanced economies, transition economies.

Explaining real exchange rate fluctuations

This paper attempts to explain the sources of real exchange rate fluctuations for a set of advanced economies and Central and Eastern European transition economies. To that end, we first estimate structural (identified) vector autoregression (SVAR) models, and decompose real and nominal exchange rate movements into those caused by real and nominal shocks. We then complete the previous step with an impulse-response analysis. There is evidence of instability in the variance decomposition of the real exchange rates for advanced economies across samples, with a growing importance of nominal shocks. Nominal shocks are also important in some transition economies.real and nominal exchange rates, real and nominal shocks, SVAR models, advanced economies, transition economies

Exchange Rate Regimes, Foreign Exchange Volatility and Export Performance in Central and Eastern Europe: Just Another Blur Project?

This paper attempts to analyze the direct impact of exchange rate volatility on the export performance of ten Central and Eastern European transition economies as well as its indirect impact via changes in exchange rate regimes. Not only aggregate but also bilateral and sectoral export flows are studied. To this end, we first analyze shifts in exchange rate volatility linked to changes in the exchange rate regimes and second, use these changes to construct dummy variables we include in our export function. The results suggest that the size and the direction of the impact of forex volatility and of regime changes on exports vary considerably across sectors and countries and that they may be related to specific periods.http://deepblue.lib.umich.edu/bitstream/2027.42/40168/3/wp782.pd

The euro and the volatility of exchange rates

This paper attempts to determine whether or not the introduction of the euro affected the volatility of bilateral exchange rates all over the world. To that end, we examine the exchange rate behaviour for a set of OECD and non-OECD countries during the 1993-2007 period. Two econometric methods are implemented for this purpose: the OLS-based tests to detect multiple structural breaks, as proposed by Bai and Perron (1998, 2003), and several procedures based on Information Criterion together with the so-called sequential procedure suggested by Bai and Perron (2003). Although results suggest evidence of structural breaks in volatility across investigated variables, there is high heterogeneity regarding the located dates. Moreover, the realignments in the Exchange Rate Mechanism seem to play a significant role in the reduction of volatility in some European countries and transition economies.Exchange rates, volatility

The Real Exchange Rate Fluctuations Puzzle: Evidence For Advanced And Transition Economies

This paper tries to analyze the sources of the real exchange rate fluctuations for a set of advanced economies and Central and Eastern European transition economies. To address this, in a first step, we compute two measures of the share of the variance of the real exchange rate accounted for movements in the relative prices of traded goods between the countries. One measure is based on R2 coefficient and the other one is based on the mean-squared error (MSE) of the changes in the real exchange rate. In a second step, we estimate structural (identified) vector autoregression (SVAR) models, and decompose real and nominal exchange rate movements into those caused by real and nominal shocks. In a third step, we complete previous ones with an impulse-response analysis. Three central messages are derived from results: (1) for transition economies, under regimes of managed nominal exchange rates, the relative price of non-traded goods explain a large percentage of the variance of the real exchange rate; (2) there is evidence of instability in the variance decomposition of the real exchange rates for advanced economies across samples, and (3) as result of diverse fiscal and monetary policies in transition economies, real exchange rates in some economies are driven mostly by real shocks while in others are driven mostly by nominal shocks

Macroeconomic Instability in the European Monetary System?

This paper analyses the impact of the establishment of the European Monetary System (EMS) on a number of macroeconomic variables, such as exchange rates, money, interest rates and prices for member countries participating in the Exchange Rate Mechanism (ERM). We examine the instability in terms of multiple structural breaks in the variance of the series. To that end, we employ two procedures: the OLS-based tests to detect multiple structural breaks, proposed by Bai and Perron (1998, 2003) and several procedures based on Information Criterion joint with the so called sequential procedure suggested by Bai and Perron (2003). Results indicate that there is some evidence of structural breaks in volatility across investigated variables, playing the realignments in the ERM a significant role in the reduction of volatility in some countries and sub-periods. In this sense, the results tend to support the hypothesis that the EMS has contributed to reduce the macroeconomic volatility of the member countries.European Monetary System, multiple structural breaks, volatility

Volatility in EMU sovereign bond yields: Permanent and transitory components

This paper explores the evolving relationship in the volatility of sovereign yields in the European Economic and Monetary Union (EMU). To that end, we examine the behaviour for daily yields for 11 EMU countries (EMU-11), during the 2001-2010 period. In a first step, we decompose volatility in permanent and transitory components using Engel and Lee (1999)´s component-GARCH model. Results suggest that transitory shifts in debt market sentiment tend to be less important determinants of bond-yield volatility than shocks to the underlying fundamentals. In a second step, we develop a correlation and causality analysis that indicates the existence of two different groups of countries closed linked: core EMU countries and peripheral EMU countries. Finally, in a third step, we make a cluster analysis that further support our results regarding the existence of two different groups of countries, with different positions regarding the stability of public finance.Conditional variance, Component model, Cluster analysis, Sovereign bond yields, Economic and Monetary Union

Structural Breaks in Volatility: Evidence for the OECD Real Exchange Rates

This paper analyses whether volatility changes in the bilateral and effective real exchange rates of the OECD industrial countries are associated with a specific nominal exchange rate regime. To that end, we examine the real exchange rate behaviour during the 1960-2003 period, therefore covering both the Bretton Woods system of fixed exchange rates and adoption of generalised floating exchange rates from 1973. We make use of an econometric methodology based on the Hansen (1997)'s approximation to the p-values of the supreme, exponential and average statistics developed by Andrews (1993) and Andrews and Ploberger (1994). This methodology allows us to obtain a profile of p-values and to delimit periods of stability and instability in the variance of real exchange rates. Results suggest that there is evidence in favour of the non-neutrality of nominal exchange rate regime regarding real exchange rate volatility.Exchange rate regimes, real exchange rate, volatility
