Four different schemes for classifying exchange rate regimes are compared for developing countries. Disagreements are substantial, and alternative schemes disagree as much with each other as with the official scheme. Only the official scheme shows a trend towards floating.

This paper studies the effects of discretionary fiscal policy shocks under different exchange rate regimes within a structural vector autoregressive (SVAR) model. We first suggest that by estimating the effects of fiscal policy shocks in two structurally similar small open economies that have opted for different monetary policy regimes (Finland and Sweden), we may control for the economic environment and study the effect of exchange rate regime on fiscal policy transmission. Second, we propose to augment the baseline model with quarterly fiscal forecasts and study fiscal policy shocks under fiscal foresight, i.e., when economic agents may anticipate and respond to fiscal policy measures prior to their implementation. Our findings suggests that discretionary fiscal policy is more effective under a fixed exchange rate regime than under a floating exchange rate regime. This is consistent with the conventional wisdom inherited from the Mundell-Fleming framework and with recent evidence that suggests the effectiveness of fiscal policy depends on the degree of monetary policy accommodation. We also find evidence that unanticipated (as opposed to standard SVAR) fiscal policy shocks have a larger expansionary effect on output than in the baseline.

This paper analyzes the optimal transition of the exchange rate regime in the People's Republic of China (PRC). How the PRC can successfully reach the desired regime - whether a basket peg or floating regime - from the current dollar-peg regime remains a major question. To answer it, we develop a dynamic small open-economy general equilibrium model. We construct four transition policies toward the basket-peg or floating regime and compare the welfare gains of these policies to those of maintaining the dollar-peg regime. Quantitative analysis using PRC data from Q1 1999 to Q4 2010 leads to two conclusions. First, a gradual adjustment toward a basket-peg regime seems the most appropriate option for the PRC, and would minimize the welfare losses associated with a shift in the exchange rate regime. Second, a sudden shift to a basket peg is the second-best solution. This is preferable to a sudden shift to a floating regime, since it would enable the authorities to implement optimal weights efficiently in order to achieve policy goals once a decision has been made to adopt a basket-peg regime.

An Asian Currency Unit (ACU) index is constructed using an alternative procedure which minimizes a basket or portfolio of assets expressed in terms of national currencies. Using this estimated ACU index and an ACU Deviation Indicator, the main finding of this study based on the current trajectory of East Asian currencies relative to this regional ACU average or benchmark is that there is a formation of two contrasting groups of countries in the region - one a group of strong currencies and the other a group of weak currencies. We emphasize that the implication of this contrasting trajectory in East Asian intra-regional exchange rates is to disturb the competitive trading relationships in the region which may result in wasteful beggar-thyneighbor policies in the region. As emphasized by other recent studies, e.g., Kawai and Takagi (2012), the region needs a kind of framework for exchange rate policy coordination that will promote intra-regional exchange rate stability. We suggest several ways in which the region can capitalize on using this ACU index in the immediate term for surveillance purposes, particularly, for purposes of assessing "over- and undervaluation" of the individual currencies from the regional ACU average and for flagging emerging vulnerabilities in individual economies in the region.

The purpose of this paper is to emphasize the importance of Europe's structural problems and governance as the cause of the current euro area crisis. The euro may have led to bubbles, but member economies were not free of trouble before the euro. Many members were losing competitiveness and in need of removing structural rigidities. If anything, the euro was expected to encourage structural reform, by taking away the easy choice of monetary and fiscal expansion. We first discuss the relationship between the single currency and economic stability in Europe. We confirm the asymmetries that remained after the introduction of the euro and then discuss the governance overhaul taking place in Europe today. This overhaul was something that should have been done before introducing the euro, and its advancement may be the silver lining of this crisis. Finally, we touch upon the implications for Asia and Japan, from the point of view of the choice of exchange rate regime as a method to advance necessary reforms.

We examine the open macroeconomic policy choices of developing economies from the perspective of the economic 'trilemma' hypothesis. We construct an index of divergence of the three trilemma policy choices, and evaluate its patterns in recent decades. We find that the three dimensions of the trilemma configurations are converging towards a 'middle ground' among emerging market economies - managed exchange rate flexibility underpinned by sizable holdings of international reserves, intermediate levels of monetary independence, and controlled financial integration. Emerging market economies with more converged policy choices tend to experience smaller output volatility in the last two decades. Emerging markets with relatively low international reserves/GDP could experience higher levels of output volatility when they choose a policy combination with a greater degree of policy divergence. Yet this heightened output volatility effect does not apply to economies with relatively high international reserves/GDP holding.

Pegging in a coordinated way to a regional basket currency is considered by many as optimal for east-Asian countries. By contrast, according to existing empirical studies, these countries have most often relied on noncooperative United States dollar or G3 pegs. We show for the first time that by the late 1990s, with some reversals, a majority of east-Asian countries had already moved, de facto, away from the dollar peg and started targeting a basket, including east-Asian currencies (an Asian Currency Unit). Common-shock or market-based interpretations of such moves are ruled out since we document that, with few exceptions, countries in the region have in reality stuck to fixed exchange rates. We obtain such results using a Markov-switching estimation benchmarked against Bai-Perron structural break tests for the synthesis model of Frankel and Wei (2007), which augments the inference about currency weights in a basket with the weight on exchange-market pressure. In order to measure the latter, the forward positions of central banks in the foreign exchange market are taken into account.

This paper revisits the issue of exchange rate regimes in emerging Asia. It is divided into two main parts. The first part compares de jure and de facto exchange rate regimes in Asia over the decade 1999-2009. It finds that while Asia is home to a wide array of exchange rate regimes, there are signs of gradual movement towards somewhat greater exchange rate flexibility in many of the regional countries. However, the propensity for foreign exchange intervention and exchange rate management among regional central banks remains fairly high in many instances. Beyond a general reluctance of many Asian economies to allow for a benign neglect of their currencies both in terms of managing volatility as well as in terms of leaning against the wind, the sustained stockpiling of reserves in developing and emerging Asian economies since 2000 (interrupted only briefly by the global financial crisis) suggests that they are more sensitive to exchange rate appreciations than to depreciations. This is the focus of the second part of the paper. We find there to be evidence of an apparent fear of appreciation which is manifested in asymmetric exchange rate intervention - i.e., a willingness to allow depreciations but reluctance to allow appreciations. This policy of effective exchange rate undervaluation is rather unorthodox from a neoclassical sense, but is consistent with a development policy centered on suppressing the price of non-tradable goods relative to tradables (i.e., real exchange rate undervaluation). The paper concludes with a few observations on the management of Asian currencies in light of the global financial crisis and concerns about global imbalances.

The real interest partity (RIP) condition combines two cornerstones in international finance, uncovered interest parity (UIP) and ex ante purchasing power parity (PPP). The extent of deviation from RIP is therefore an indicator of the lack of product and financial market integration. This paper investigates whether the nominal exchange rate regime has an impact on RIP. The analysis is based on 15 annual real interest rates and covers a long time span, 1870-2006. Four subperiods are distinguished and linked to fixed and flexible exchange rate regimes: the Gold Standard, the interwar float, the Bretton Woods system and the current managed float. Panel integration techniques are used to increase the power of the tests. Cross section correlation is embedded via common factor structures. The results suggest that RIP holds as a long run condition irrespectively of the exchange rate regimes. Adjustment towards RIP is affected by the institutional framework and the historical episode. Half lives of shocks tend to be lower under fixed exchange rates and in the first part of the sample, probably due to higher price flexibility before WWII. Although barriers to foreign trade and capital controls were substantially removed after the collapse of the Bretton Woods system, they did not lead to lower half lives during the managed float.

Set in the context of the recent theoretical and policy debates on appropriate exchange rate regimes for emerging market economies in a world of free capital mobility, the paper attempts to present the case for an intermediate exchange rate regime, drawing on recent theoretical and empirical literatures on behavioural finance and currency market structures; and to examine empirically the experiences and evolution of Brazil's foreign exchange market under different exchange rate regimes.

We discuss how the welfare ranking of fixed and flexible exchange rate regimes in a New Open Economy Macroeconomics model depends on the interplay between the degree of exchange rate pass-through and the elasticity of substitution between home and foreign goods. We identify combinations of these two parameters for which flexible and for which fixed exchange rates are superior with respect to welfare as measured by a representative household's utility level. We estimate the two parameters for six non-EMU European countries (Czech Republic, Hungary, Poland, Slovakia, Sweden, United Kingdom) using a heterogeneous dynamic panel approach.

Using the indexes we developed (Aizenman, Chinn, and Ito, 2008) to measure the degree of the three policy choices countries make with respect to the trilemma: exchange rate stability, monetary independence, and capital account openness, we investigate the normative questions pertaining to the trilemma, that is, how the policy choices among the three trilemma policies affect output growth volatility, inflation rates, and the volatility of inflation, with focus on developing economies. Some key findings for developing countries include: (i) greater monetary independence can dampen output volatility while greater exchange rate stability implies greater output volatility, which can be mitigated by reserve accumulation; (ii) greater monetary autonomy is associated with a higher level of inflation while greater exchange rate stability and greater financial openness could lower the inflation level; (iii) a policy pursuit of stable exchange rate while financial development is at the medium level can increase output volatility, and while greater financial openness with a high level of financial development can reduce output volatility, greater financial openness with a low level of financial development can be volatility increasing; (iv) net inflow of portfolio investment and bank lending can increase output volatility and higher levels of short-term debt or total debt services can increase both the level and the volatility of inflation.

We argue that a higher share of the private sector in a country's external debt raises the incentive to stabilize the exchange rate. We present a simple model in which exchange rate volatility does not affect agents' welfare if all the debt is incurred by the government. Once we introduce private banks who borrow in foreign currency and lend to domestic firms, the monetary authority has an incentive to dampen the distributional consequences of exchange rate fluctuations. Our empirical results support the hypothesis that not only the level, but also the composition of foreign debt matters for exchange-rate policy.

The role of the exchange rate under inflation targeting (IT) remains an unresolved issue in literature and policy discussions -and a challenge for central banks implementing IT, especially in developing countries. This paper aims at assessing whether there is a relation between the nominal exchange rate regime and inflation performance in IT countries. We use a panel of 22 countries that adopted IT between 1990 and 2006, and estimate models in order to determine whether an exchange rate regime that differs from a pure float entails higher or lower inflation. We use two de facto foreign exchange regime classifications (Levy-Yeyati and Sturzenegger, 2005; Reinhart and Rogoff, 2004), and a de jure one (IMF). We estimate regressions through methods that account for the dynamic character of the panel ('difference' and 'system' GMM estimators). We deal with potential endogeneity between inflation performance and exchange rate regime choice through the use of instrumental variables. In order to check the robustness of the results, we use alternative specifications -by including different macroeconomic control variables-, and introduce changes in the sample -by using a balanced and an unbalanced panel-. Our results suggest that the choice of exchange rate regime matters for IT countries: de facto arrangements that are less flexible than pure floats appear to deliver lower inflation, especially in developing countries. This is consistent with the fact that those countries have higher pass through coefficients and are more prone to the kind of problems dubbed as 'fear of floating'.

This study documents a quantitative analysis of exchange rate volatilities and misalignment in Uzbekistan for the period of 1994q3-2005q2. The results suggest that the real exchange rate volatility and misalignment have depressing effects on the volume of trade, mainly exports in Uzbekistan. The Government's currency rationing policy was lessening the volatility proving that the policy-induced changes in exchange rate has a stabilizing effect on trade flows. The implied elasticity for the most significant real exchange rate volatility coefficient is -0.20. Using a two-step Engle-Granger technique import demand and export supply price elasticities are computed. The results are consistent with the predictions from a number of previous studies, and in particular, the estimated exports price elasticity for Uzbek economy ranges from 1.65 to 1.84, while import demand price elasticity is between -0.78 and -0.83. At the same time, relatively lower elasticity during 'the currency rationing' period indicate that large devaluations, most likely, did not generate the expected improvements in the overall export performance.

This paper estimates export and import price equations for 41 countries –including 28 emerging market economies. Further, it relates the estimated elasticities to structural factors and tests for statistical breaks in the relation between trade prices and exchange rates. Results indicate that (i) the elasticity of trade prices in emerging markets is sizeable, but not significantly higher than in advanced economies; (ii) such elasticity is primarily influenced by macroeconomic factors such as the exchange rate regime and the inflationary environment, although microeconomic factors such as product differentiation also play a role; (iii) export and import price elasticities tend to be strongly correlated across countries; (iv) pass-through to import prices has declined in some advanced economies, noticeably the United States; this is consistent with a rise in pricing-to-market in several EMEs and especially with a change in the geographical composition of U.S. imports.

In this paper Friedmann (1953) and Mundell´s (1968) position favouring flexible over alternative exchange rate regimes is reassessed in the context of international financial market integration. In a new open economy macroeconomic framework the paper shows that financial market integration causes a monetary policy trade-off between stabilising domestic goods prices as opposed to stabilising the terms of trade. Therefore, the welfare ranking of different exchanges rate rules changes during the process of international financial integration. It becomes evident that no single exchange rate regime outperforms in stabilising both domestic consumption and output variability in the process of financial market integration.

We develop a methodology that intuitively characterizes the choices countries have made with respect to the trilemma during the post Bretton-Woods period. The paper first outlines the new metrics for measuring the degree of exchange rate flexibility, monetary independence, and capital account openness while taking into account the recent development of substantial international reserve accumulation. The evolution of our trilemma indexes illustrates that, after the early 1990s, industrialized countries accelerated financial openness, but reduced the extent of monetary independence while sharply increasing exchange rate stability, all reflecting the introduction of the euro. In contrast, emerging market countries pursued exchange rate stability as their key priority up to the late 1980s while non-emerging market developing countries has pursued it throughout the period since 1970. As a stark difference from the latter group of countries, emerging market countries have converged towards intermediate levels of all three indexes, characterizing managed flexibility while retaining some degree of monetary autonomy and accelerating financial openness. This recent trend appears to be sustained by using sizable international reserves as a buffer. We also confirm that the weighted sum of the three indexes adds up to a constant, validating the notion that a rise in one trilemma variable should be traded-off with a drop of the weighted sum of the other two. The second part of the paper deals with normative aspects of the trilemma, relating the policy choices to macroeconomic outcomes such as the volatility of output growth and inflation, and medium term inflation rates. Some key findings for developing countries include: (i) greater monetary independence can dampen output volatility while greater exchange rate stability implies greater output volatility, which can be mitigated by reserve accumulation; (ii) greater monetary autonomy is associated with a higher level of inflation while greater exchange rate stability and greater financial openness could lower the inflation level; (iii) a policy pursuit of stable exchange rate while financial development is at the medium level can increase output volatility, (iv) greater financial openness with a high level of financial development can reduce output volatility, though greater financial openness with a low level of financial development can be volatility-increasing; (v) net inflow of portfolio investment and bank lending can increase output volatility and higher levels of short-term debt or total debt services can increase both the level and the volatility of inflation.

This paper attempts to model the nominal and real exchange rate for Ireland, relative to Germany and the UK from 1975 to 2003. It offers an overview of the theory of purchasing power parity (PPP), focusing particularly on likely sources of nonlinearity. Potential difficulties in placing the analysis in the standard I(1)/I(0) framework are highlighted and comparisons with previous Irish studies are made. Tests for fractional integration and nonlinearity, including random field regressions, are discussed and applied. The results obtained highlight the likely inadequacies of the standard cointegration and STAR approaches to modelling, and point instead to multiple structural changes models. Using this approach, both bilateral nominal exchange rates are effectively modelled, and in the case of Ireland and Germany, PPP is found to be valid not only in the long run, but also in the medium term.

Official and four alternative regime classification schemes based on observed exchange rate behaviour are used to examine the relationship with inflation and growth in developing countries. For an identical sample of observations from 73 countries for 1984-2001, only the scheme based on parallel rates suggests a significant effect (negative) of floating on growth. Floats that claim to be pegs, or have high exchange rate volatility, are the ones with lower growth. Hard pegs offer inflation benefits. Floating is not consistently associated with higher inflation than soft pegs, and any apparent association is a possible by-product of the design of the classification algorithms.

We study the apparent disconnect between what countries announce to be their exchange rate regime and what they de facto implement. Even though discrepancies between announcements and de facto polices are frequent, there is a lack of understanding of actual patterns and underlying reasons. We contribute to the literature by identifying a number of robust stylized facts by means of an in-depth analysis of a large cross-country dataset. A key insight is that countries that operate under intermediate de facto regimes tend to announce fixed or flexible exchange rate regimes. The exact nature of deviations is related to country characteristics such as trade structure, financial development, and financial openness. Furthermore, regime discrepancies have followed secular trends, which are most likely related to financial globalization and changes in monetary policy design.

This paper examines whether the behaviour of the real exchange rate is associated with a particular regime for the nominal exchange rate, like fixed and flexible exchange rate arrangements. The analysis is based on 16 annual real exchange rates and covers a long time span, 1870-2006. Four subperiods are distinguished and linked to exchange rate regimes: the Gold Standard, the interwar float, the Bretton Woods system and the managed float thereafter. Panel integration techniques are applied to increase the power of the tests. Cross section correlation is embedded via common factor structures. The evidence shows that real exchange rates properties are affected by the exchange rate regime, although the impact is not very strong. A unit root is rejected in both fixed and flexible exchange rate systems. Regarding fixed-rate systems, mean reversion of real exchange rates is more visible for the Gold Standard. The half lives of shocks have increased after WWII, probably due to a higher stickiness of prices and a lower weight of international trade in the determination of exchange rates. Both for the periods before and after WWII, half lives are lower in flexible regimes. This suggests that the nominal exchange rate plays some role in the adjustment process towards PPP.

This paper develops a flexible price, two-sector nominal growth model, in order to study the role of the exchange rate regime in capital accumulation (convergence). We adopt a standard model of a small open economy with traded and nontraded goods, and enrich its structure with costly investment and a preference for real money holdings. We find that (i) the choice of exchange rate regime influences the transition dynamics of a small open economy, (ii) a one-sector model does not adequately capture the channels through which the nominal side interacts with real variables, and (iii) as a consequence, sectoral asymmetries are important for understanding the effects of the exchange rate regime on capital accumulation.

Recent studies on the growth effects of exchange rate regimes offer a wide range of different, sometimes contradictory results. In this paper, we systematically compare three prominent contributions in this field. Using a common data set, a common specification, and common estimation methods, we argue that the contradictory findings can be explained by the fact that these studies use regime classifications which reflect fundamentally different aspects of exchange rate policy.

We investigate monetary-policy autonomy under different exchange-rate regimes in small, open European economies during the 1980s and 1990s. We find no systematic link between ex post monetary-policy autonomy and exchange rate regimes. This result is enforced for countries/periods with alternative nominal targets. Our interpretation of the results is that over the medium and long term following an ‘independent’ target for monetary policy, which does not deviate much from the targets of those countries to which one is closely financially integrated, is as constraining as locking the exchange rate to some particular level

We show that the credibility gain from permanently committing to a fixed exchange rate by joining the European Monetary Union can outweigh the loss from giving up independent monetary policy if the domestic monetary authority does not enjoy full credibility. Using a DSGE model, this paper shows that when the central bank enjoys only limited credibility a pegged exchange rate regime yields a lower loss compared to an inflation targeting policy, even if this policy ranking would be reversed in a full-credibility environment. There exists an initial stock of credibility that must be achieved for a policy-maker to adopt inflation targeting over a strict exchange rate targeting regime. Full credibility is not a precondition, but exposure to foreign and financial shocks and high steady state inflation make joining the EMU relatively more attractive for a given level of credibility. The theoretical results are consistent with empirical evidence we provide on the relationship between credibility and monetary regimes using a Bank of England survey of 81 central banks.

Lack of commitment in monetary policy leads to the well known Barro-Gordon inflation bias. In this paper, we argue that two phenomena associated with the time inconsistency problem have been overlooked in the exchange rate debate. We show that, absent commitment, independent monetary policy can also induce expectation traps - that is, welfare-ranked multiple equilibria - and perverse policy responses to real shocks - that is, an equilibrium policy response that is welfare inferior to policy inaction. Both possibilities imply higher macroeconomic volatility under flexible exchange rates than under fixed exchange rates.

This paper investigates the implications of alternative scale variables of money demand for the comparison of a flexible exchange rate regime with a monetary union in a NOEM setup. The welfare evaluation of exchange rate regimes depends on the exchange rate response under the flexible regime. When the scale variable is private consumption, a domestic fiscal expansion yields a depreciation. As the associated expenditure switching and terms-of-trade effects are beneficial to the domestic country, households prefer flexible exchange rates. However, when the scale variable is total absorption, we obtain an appreciation and the welfare results are reversed.

This paper uses a panel probit model with simultaneous equations to explain the joint determination of de facto and de jure exchange rate regimes in developing countries since 1980. We also derive an ordered-choice panel probit model to explain the causes of discrepancies between the two regime choices. Both models are estimated using simulation-based maximum likelihood methodsl. The results of the simultaneous equations model suggest that the two regime choices are dependent of each other and exhibit considerable state dependence. The ordered probit model provides evidence that regime discrepancies reflect an error-correction mechanism, and the discrepancies are persistent over time.

This paper analyses the choices of exchange rate regimes in developing countries since 1980. Static and dynamic random-effects multinominal panel models are estimated using simulation-based techniques. Explanatory variables include OCA fundamentals, stabilization considerations, currency crises factors, and political and institutional features. The results reveal strong state dependence in regime choices.

A two sector small open economy model developed by Corden (1991, 2002) is used to analyse the impact of sudden stops in capital inflows on an internal and external equilibrium and to explore the merits of disposing of the nominal exchange rate as policy tool in rectifying real exchange rate misalignments. It is shown how the economy's sectoral demand properties determine the extent of recession associated with real exchange rate adjustment that is neither engineered by nominal exchange rate changes nor brought about by a decline in nontraded goods prices. The conclusion is drawn that, when deciding on the design of exchange rate regimes, the structural characteristics of the economy ought to be considered so as to appropriately strengthen its capacity to cope with shocks in the form of negative swings in capital inflows.

Based on a broad set of regional aggregated and disaggregated consumer price index (CPI) data from major industrialized countries in Asia, North America and Europe we are examining the role that national borders play for goods market integration. In line with the existing literature we find that intra-national markets are better integrated than international market. Additionally, our results show that there is a large 'ocean' effect, i.e., intercontinental markets are significantly more segmented than intra-continental markets. To examine the impact of the establishment of the European Monetary Union (EMU) on integration, we split our sample into a pre-EMU and EMU sample. We find that border effects across EMU countries have declined by about 80% to 90% after 1999 whereas border estimates across non-EMU countries have remained basically unchanged. Since global factors have affected all countries in our sample similarly and major integration efforts across EMU countries were made before 1999, we suggest that most of the reduction in EMU border estimates has been 'nominal'. Panel unit root evidence shows that the observed large differences in integration across intra- and inter-continental markets remain valid in the longrun. This finding implies that real factors are responsible for the documented segmentations across our sample countries.

Japan and Korea are close countries in terms of economic interaction as well as geography. To quantify the impact of changes in the yen-dollar exchange rate on the Korean economy before and after the crisis in 1997, the sample period has been divided into two sub-periods and the causal relationships examined by using vector autoregression analysis. Our estimates show that while the response of Korean industrial production to changes in the yen-dollar exchange rate was not significant during the pre-crisis period, it became significant during the post-crisis period. The forecast error variance decomposition also confirms that the yen-dollar exchange rate shocks have almost negligible explanatory power with regards to Korean industrial production during the pre-crisis period, but they have some significance for the postcrisis period. These empirical results show that the free floating exchange rate regime adopted since the crisis cannot insulate the Korean economy from external nominal shocks such as the yen-dollar exchange rate shocks.

In this paper I investigate the relevance of the exchange rate regime for macroeconomic stability. I simulate hypothetical macroeconomic developments under different regimes in Sweden during the period 1972 -1996. The main question is how stable output would have been if Sweden had had a floating exchange rate regime. Would it have been better with a floating exchange rate than the actual quasi-fixed regime? Also the development with an irrevocably fixed exchange rate is investigated. The results indicate that the central bank can stabilize much of the macroeconomic disturbances under a floating exchange rate, but still the volatility of the macroeconomic variables under the hypothetical floating exchange rate regime is about the same as under the actual quasi-fixed regime.

Large differences in national price levels exist across countries. In this paper, I develop a general equilibrium model predicting that these differences should be related to countries' exchange rate regimes. My empirical findings confirm that countries with fixed exchange rate regimes have higher national price levels than countries with flexible regimes. At the disaggregate level, the relationship between exchange rate regimes and national price levels is stronger for nontraded goods than for traded goods. I also find that measuring the misalignment in national price levels around times of regime shifts without considering a break in its equilibrium value results in the overestimation of the true misalignment.

During the Asian crisis, intermediate exchange rate regimes vanished. It has been argued that those regimes were no longer useful and only the extremes remained valid. The paper analyses three foreign exchange regimes: Argentina (pegged), Chile (band) and Mexico (float). The Argentinean currency board delivered low financial volatility while it was credible, but even then it displayed high real volatility. Mexican float performed well in periods of instability isolating the real sector. The Chilean band delivered a mixed outcome as compared to Argentina and Mexico. This is linked apparently to a loss in the band’s credibility, associated to policy mismanagement and an over-appreciation in the biennium before the crisis. Optimal exchange rate regimes vary across time and the conjuncture. Exit strategies are part of the election of the optimal system, including a flexible policy package rather than a single rigid policy tool.

This paper examines the relationship between the exchange rate regime and trade flows using a general equilibrium model based on Bacchetta and van Wincoop (AER, 2000). We show that in general the link between trade and the exchange rate regime is ambiguous and that it depends in particular on the nature of macroeconomic shocks and consumer preferences. A critical aspect is the pricing strategy adopted by monopolistically competitive firms. Trade is more likely to be affected by the exchange rate regime if firms price in buyers' currency, or price to market (PTM), than if they price in producers' currency (PCP). We show, however, that PCP is not an equilibrium under reasonable parameters when international capital markets are not available. In contrast, when markets become more complete, firms tend to switch to PCP.

We develop a simple general equilibrium framework to study the effect of the exchange rate system on trade and welfare. An important feature of the model is deviations from purchasing power parity, caused by rigid price setting in buyers' currency. We find the following. First, exchange rate stability is not necessarily associated with more trade.In a simple benchmark model with separable preferences and only monetary shocks, trade is unaffected by the exchange rate system, consistent with most evidence. Second, both trade and welfare can be higher under either exchange rate system, depending on preferences and on the monetary policy rules followed under each system. Finally, in general there is no one-to-one relationship between the levels of trade and welfare across exchange rate systems.
