The equilibrium exchange rates of European currencies and the transition to euro

This study estimates the demand system using Japanese micro data and calculates the cost of living index (COLI) to assess the substitution bias in the Consumer Price Index. The estimated bias during the sample period of 1982–2000 is about 0.06 percentage points, which is larger than the estimates calculated from a superlative index. The difference between the COLI and a superlative index can be explained with the upward movements of the average utility level in Japan, since the cost of living for the rich has grown more rapidly than that for the poor.     

Pegging emerging currencies in the face of dollar swings

The aim of this article is to study ruptures of exchange rate pegs by focusing on the fluctuations of the anchor currency. We test for the hypothesis that currencies linked to the USD are more likely to loosen their peg when the USD is appreciating, while sticking to it otherwise. To this end, we estimate smooth-transition regression models for a sample of 28 emerging currencies over the 1994–2011 period. Our findings show that while the real effective exchange rates of most of these countries tend to co-move with that of the USD in times of depreciation, this relationship is frequently reversed when the US currency appreciates over a certain threshold.     

External debt and real exchange rates’ adjustment in the euro area: new evidence from a nonlinear NATREX model

In this article, we revisit medium- to long-run real exchange rate determination within the euro area, focusing on the role of external debt. Accordingly, we rely on the NATural Real EXchange rate (NATREX) approach which provides an explicit framework of the external debt–real exchange rates nexus. In particular, given the indebtedness levels reached by the euro area economies, we investigate potential nonlinearity in real exchange rates dynamics, according to the level of the external debt. Our results evidence that during the monetary union, gross and net external debt positions of the euro area countries have exerted pressures on real exchange rate dynamics within the area. Moreover, we find that, beyond a threshold reached by the external debt, euro area countries are found to be in a vulnerable position, leading to an unavoidable adjustment process. Nevertheless, the adjustment process, while effective, is found to be low and occurs slowly.     

Exchange rate volatility across financial crises

This paper studies the impact of global financial turmoil on the exchange rate policies in emerging countries. Spillovers from advanced financial markets to currencies in emerging countries are likely to be exacerbated during crisis periods. To test this hypothesis, we assess the exchange rate policies by currencies’ volatility and investigate their relationship to a global financial stress indicator, measured by the volatility on global markets. We introduce the possibility of nonlinearities by running smooth transition regressions over a sample of 21 emerging countries from January 1994 to September 2009. The results confirm that exchange rate volatility does increase more than proportionally with the global financial stress, for most countries in the sample. We also evidence regional contagion effects spreading from one emerging currency to other currencies in the neighboring area.     

Currency Misalignments and Exchange Rate Regimes in Emerging and Developing Countries*

Pegged exchange rates are often pointed out as more prone to risk of overvaluation, because their real exchange rates have a tendency to appreciate. We check this assumption empirically over a large sample of emerging and developing countries, by using two databases for de facto classifications by Levy‐Yeyati and Sturzenegger (2003 ) and by Reinhart and Rogoff (2004 ). We assess currency misalignments by estimating real equilibrium exchange rates taking into account a Balassa effect and the impact of net foreign assets. Pegged currencies are shown to be more overvalued than floating ones.     

FOSSIL FUEL SUBSIDIES,INCOME INEQUALITY,AND POVERTY: EVIDENCE FROM DEVELOPING COUNTRIES

The past two decades have witnessed widespread attempts to reform fossil fuel subsidies in developing countries. If the reforms are likely to improve economic efficiency, the expected effects on income distribution and poverty are more controversial. This paper reviews the recent literature that examines the impacts of fossil fuel subsidies and their reforms on income inequality and poverty in developing countries. It identifies the different channels that have been explored in the literature and surveys the empirical evidence on the importance of these channels in practice. Drawing on diverse country experiences, it also discusses why fossil fuel subsidies are particularly challenging to reform and highlights several ways in which efforts to reform may be feasible and successful.     

The Determination of the Equilibrium Exchange Rate in a Simple General Equilibrium Model

In this article, we develop an analytical general equilibrium model of the equilibrium exchange rate for emerging countries. This theoretical framework allows us to identify a relevant set of variables which determinate the equilibrium exchange rate and to explore how these variables influence the trajectory of the equilibrium exchange rate.     

The Exchange Rate Macroeconomic Balance Approach: New Methodology and Results for the Euro,the Dollar,the Yen and the Pound Sterling

This paper presents an extension of the macroeconomic exchange rate balance approach. This extension comprises two new aspects. Firstly, it is based on a multinational framework which allows for macroeconomic linkages between countries. Secondly, it uses a procedure that does not require a full modeling of the world economy to derive a consistent set of equilibrium exchange rates. The findings reveal that, in 2001, the dollar was overvalued against the euro and the yen. The paper also shows that this result depends heavily on the chosen notion of current account sustainability.     

Does Euro or Dollar Pegging Impact the Real Exchange Rate? The Case of Oil and Commodity Currencies

The aim of this paper is to investigate the equilibrium exchange rates for commodity and oil currencies as well as the discrepancies of their observed exchange rates to these equilibriums. To this end, first, we estimate a long‐term relationship between the real effective exchange rate and economic fundamentals, including the commodity terms of trade. The estimation relies on panel cointegration techniques and covers annual data from 1980 to 2007. Our results show that real exchange rates co‐move with commodity prices in the long run and respond to oil price somewhat less than to commodity prices. Second, we assess the degree of misalignment of these currencies, as the gap between their observed exchange rate and the estimated equilibrium exchange rate. We show that these misalignments are not significantly related to the exchange rate regimes adopted by the countries, either pegged or floating. However, for pegged currencies, the size of misalignments significantly depends on the anchor currency, either the euro or the dollar. A comparison of misalignments of pegged commodity and oil currencies across different periods confirms these results: during periods of dollar (euro) overvaluation, currencies pegged to the dollar (euro) tend to be overvalued; the reverse being true when the dollar (euro) is undervalued. Consequently, pegged currencies are often driven away from their equilibria by wild fluctuations in the key currencies, on which they are anchored.     

Oil currencies in the face of oil shocks: what can be learned from time-varying specifications?

While the oil currency property is clearly established from a theoretical viewpoint, its existence is less clear-cut in the empirical literature. We investigate the reasons for this apparent puzzle by studying the time-varying nature of the relationship between real effective exchange rates of five oil exporters and the real price of oil in the aftermath of the oil price shocks of the last two decades. Accordingly, we rely on a time-varying parameter VAR specification, which allows the responses of real exchange rates to different oil price shocks to evolve over time. We find that the reason of the mixed results obtained in the empirical literature is that oil currencies follow different hybrid models in the sense that oil countries’ real exchange rates may be driven by one or several sources of oil price shocks that furthermore can vary over time. In addition to structural changes affecting oil countries, structural changes arising from the oil market itself through the various, time-varying sources of oil price shocks are found to be crucial.
