Real exchange rates in emerging economies

We analyse the role of various investment margins in explaining the real exchange rate appreciation recorded in European transition countries. We present a model that introduces a quality investment margin and show that the margin is needed for replicating the observed pace of real exchange rate appreciation.     

Bilateral real exchange rates and migration

Migrants who move across borders are, to a large extent, motivated by the prospect of earning higher incomes at destination, which can be partly transferred back to their countries of origin via remittances. This suggests that the real exchange rate can influence the incentives to migrate, as it determines the purchasing power of expected income in terms of the currency of the origin country. This article investigates empirically how bilateral real exchange rate fluctuations influence international migration flows. To do so, we build a dataset of 30 OECD destination countries and 165 origin countries over the period 1980–2011 and estimate an equation derived from a micro-founded random utility maximization model that allows for unobserved heterogeneity between migrants and non-migrants. Our results show that migration flows are highly responsive to bilateral real exchange rates: A 10% real appreciation of the currency of the destination country is associated with an 18.2–19.4% increase in migration flows.     

Production, trade, prices, exchange rates and equilibration in large experimental economies

We study market equilibration in laboratory economies that are larger and more complex than any that have been studied experimentally to date. Complexity is derived from the fact that the economies are “international” in economic structure with multiple input, output, and foreign exchange markets in operation. The economies have twenty-one markets and due to the fact that they have roughly fifty agents, the economies are characterized by several hundred equations. In spite of the complexity and interdependence of the economy, the results demonstrate the substantial power of the general equilibrium model of perfect competition to predict the direction of movement of market-level variables. Empirical patterns in the convergence process are explored and described.     

The inadequacy of linear autoregressive model for real exchange rates: empirical evidence from Asian economies

Utilizing the formal linearity test of Luukkonen, Saikkonen and Teräsvirta (Biometrika, 75, 491-499, 1998) as diagnostic tool, the empirical finding suggests that the linear autoregressive (AR) model is inadequate in describing the real exchange rates behaviour of 11 Asian economies. It is noted that the conventional battery of diagnostic tests is capable of identifying the inadequacy of the linear model in only three of these series. Moreover, the linearity nature of this behaviour has been formally rejected in favour of the non-linear smooth transition autoregressive (STAR) model. The finding of non-linearity in the data generating process of these real exchange rates warrants that the use of linear framework in empirical modelling and statistical testing procedures in the field of exchange rates may lead to an inappropriate policy conclusions.     

Large real exchange rate movements, firm dynamics, and productivity growth

Abstract.  This paper examines the influence of large real exchange rate movements on firm turnover and production scale, and the contribution of these decisions to productivity growth. Our theoretical model predicts that home currency appreciations cause firm closure and reduce surviving firms' exports while boosting domestic sales. The net effect on sales and productivity therefore depends on changes in domestic sales and exports. Taiwanese firm-level data are used to test these predictions. The results show that real currency appreciations lead to scale expansion of surviving firms which in turn raises productivity. Our findings suggest the existence of a significant scale effect.     

Home bias, distribution services and determinants of real exchange rates

This paper examines empirically how exogenous changes in the terms of trade affect the real exchange rate through the relative price of traded goods with Canada–US data. The relative price of traded goods is constructed using prices at the dock and retail prices. The first measure emphasizes the importance of home bias in consumption of traded goods. The second measure highlights the importance of distribution services required for consumption of traded goods. It is found that terms of trade shocks affect the relative price of traded goods using both measures. A possible interpretation of empirical findings is that home bias and distribution services are important for understanding the relative price of traded goods.     

Decomposing the persistence of real exchange rates

We propose a new methodology for decomposing the persistence of deviations from purchasing power parity (PPP). By directly comparing the impulse response function (IRF) of a vector autoregressive (VAR) model, where the real exchange rate is Granger caused by a set of candidate variables, with the IRF of the equivalent ARMA model for the real exchange rate, we capture the effects of the Granger-causing variables on the half-life of deviations from PPP. Our empirical results for a set of 20 industrial countries suggest that on average around 50% of the persistence of real exchange rates can be attributed to nominal interest rate differentials, inflation differentials and relative business cycle position with the numenaire country. Finally, we provide confidence intervals for the contributions of the aforementioned variables to the persistence of deviations from PPP by means of Monte Carlo simulations.     

Removing foreign direct investment's exchange rate risk in developing economies: the case for a foreign exchange custodian board

This paper proposes a system design (foreign exchange custodian board) that may stimulate foreign direct investment (FDI) in developing economies through the removal of foreign investors' exchange rate risk in investment outlay. For any expected distribution of exchange rate on any interval around the starting exchange rate, there exists a non-negative custodian service charge that both the developing economy and foreign investors can benefit from the proposed system. When the increase in domestic factors' value added caused by FDI is sufficiently large, the developing economy will benefit even in the absence of any custodian service charge.     

A macroeconomic model for open economies with pegged exchange rates

Most traditional analyses of the internal-external adjustment problem has been based upon a model with only two assets, money and bonds. In this paper real capital is explicitly introduced. As a logical consequence also the investment function is assumed to be different from standard specifications. With this model the effects of monetary and fiscal policy are then shown to be substantially different from traditional results.     

Home bias and the persistence of real exchange rates

This paper investigates the half-life of real exchange rates after taking into account the impact of home bias. Empirical results indicate that the half-life of real exchange rates is in the range of 1.5 to 2 years for four out of five countries after controlling the impact of home bias. These results support Obstfeld and Rogoff's (2000, NBER Macroeconomics Annual) view that home bias is crucial in explaining the PPP puzzle.     

Openness,productivity and growth in the APEC economies

The 1980s and 1990s have witnessed the emergence of many Asian economies as important traders in the world. How has openness to trade and investment affected productivity and growth performance in those economies? This question is often tackled with the traditional growth regression method. However, the findings in the existing literature are still inconclusive. This paper proposes an alternative approach which is employed to examine the impact of openness on the sources of productivity and growth in the APEC economies. Specifically, the proposed technique distinguishes technological progress (innovation) from efficiency changes (catch-up) and attempts to isolate the influences of openness on these two distinct factors. The findings in this study may help gain fresh insight into the relationship between openness and productivity and growth performance in the APEC economies.First revision received: July 2001/Final revision received: May 2003The author thanks two anonymous referees for very helpful comments.     

Precautionary demand for foreign assets in Sudden Stop economies: An assessment of the New Mercantilism

Financial globalization had a rocky start in emerging economies hit by Sudden Stops. Foreign reserves have grown very rapidly since then, as if those countries were practicing a New Mercantilism that views foreign reserves as a war chest for defense against Sudden Stops. This paper conducts a quantitative assessment of this argument using a stochastic intertemporal equilibrium framework in which precautionary foreign asset demand is driven by output variability, financial globalization, and Sudden Stop risk. In this framework, credit constraints produce endogenous Sudden Stops. We find that financial globalization and Sudden Stop risk can explain the surge in reserves but output variability cannot. These results hold using the intertemporal preferences of the Bewley–Aiyagari–Hugget precautionary savings model or the Uzawa–Epstein setup with endogenous impatience.     

Jumps in foreign exchange rates and stochastic unwinding of carry trades

Tails in the distribution of JPY/USD exchange rate returns are well approximated by an exponentially dampened power-law. Distribution parameter estimates indicate that yen appreciation jumps belong to a Levy process with unbounded variation, suggesting that same mechanism may be responsible for fluctuations in normal times as well as rare crashes. In contrast, yen depreciation jumps have a well defined second moment suggesting a Gaussian regime. In addition, extreme episodes of yen appreciation are larger and more persistent than episodes of yen depreciation. The asymmetry is magnified and power-law tails are more elongated during times of higher interest rate differential between U.S. and Japan and higher level of VIX indicating that carry trade may be the driver. We propose a model of strategic carry trader behavior that in equilibrium generates exponentially dampened power-law distribution of jumps in foreign exchange along with “up by the stairs down by the elevator” dynamics arising from the assymetries between negative and positive jumps.     

Demand,employment, and labour productivity in the European economies

This paper presents an explanation of the causes of the slowdown in growth in labour productivity in European economies in recent decades. In first instance, the weakness of domestic demand is what determines this slowdown in productivity. However, differences with the (mediocre) rates of growth of productivity between European countries are also related to the specific features of their respective labour markets because, in a context of weak domestic demand, there is a trade-off between employment and productivity.     

Long memory and mean reversion in real exchange rates in Latin America

This article examines the long-run Purchasing Power Parity (PPP) hypothesis for 12 Latin American Real Effective Exchange Rates (REERs) using fractional integration techniques. The empirical results, applying parametric approaches, provide evidence of mean reversion in the REERs in the cases of Nicaragua, Belize, Costa Rica, Guyana and Paraguay and lack of it for the remaining seven countries. Employing semiparametric methods, the evidence of mean reversion covers the following countries: Belize, the Dominican Republic, Ecuador and Mexico. Thus, only for Belize and Guyana do we obtain consistent evidence of mean reversion in the real exchange rates. At the other extreme, lack of mean reversion, and thus, lack of PPP, is obtained with both methods in Bolivia, Brazil, Colombia and Venezuela. For the remaining six countries, the results are ambiguous. The results for the PPP theory in Belize and Guyana may show the importance of promoting policies based on exchange rate flexibility and economic liberalization to reach a long-run stability scenario that leads to greater international competitiveness and lower external vulnerability.     

Equity in exchange economies

Let ψ be a “fair” choice correspondence, i.e., ψ associates to every economy in some initial position a set of final allocations at which the gains from trade have been fairly distributed. We propose to declare equitable any final allocation which is invariant under arbitrary permutations among the agents of the components of the initial allocation, followed by the operation of ψ. We also formulate a series of other criteria patterned on this model, and we investigate the existence of allocations satisfying these criteria for several natural choices of ψ.
