One might expect that differences in income elasticities in trade and/or differences in growth rates among countries would give rise to strong secular trends in real exchange rates; for example, fast-growing countries might need steady depreciation to get the world to accept their growing exports. In fact, however, income elasticities are systematically related to growth rates by the "45-degree rule", under which fast-growing countries appear to face high income elasticities of demand for their exports, while having low income elasticities of import demand. The net effect of this relationship between elasticities and growth rates is that secular trends in real exchange rates are much smaller than one might otherwise have expected: relative PPP holds fairly well. This paper documents the existence of a "45-degree rule", and suggests an explanation in terms of increasing returns and product differentiation.

The Houthakker-Magee effect implies that a country facing unfavorable income elasticities in trade must either grow at a slower rate than its trading partners or experience a trend worsening of its current account and/or depreciation of its real exchange rate. Krugman (1989) first documented the existence of a “45-degree rule” under which relative income elasticities are systematically related to relative growth rates. In this paper, we develop and test an intertemporal current account model in which Krugman’s original 45-degree rule is a special case. The result suggests that secular trends in current accounts and/or real exchange rates are much smaller than one would have projected based on conventional income elasticities.

There is an ongoing debate in the literature on whether global trade flows have become disconnected from the large real effective exchange rate movements in the wake of the global financial crisis. The question has important policy implications for the role of exchange rates in supporting growth and restoring external balance. In this paper, we use Turkey---a large and open emerging market economy that has experienced sizable swings of the real effective exchange rate---as a case study to test competing hypotheses. Our results lend support to the finding in existing cross-country studies that the real effective exchange rate remains an important determinant of trade flows. But, its effect is not symmetric in secular periods of appreciation and depreciation and is, oftentimes, dwarfed by the impact on trade flows of the income growth differential between trade partners.

Abstract: The view that policies directed at the real exchange rate can have an important effect on economic growth has been gaining adherents in recent years. Unlike the traditional "misalignment" view that temporary departures of the real exchange rate from its equilibrium level harm growth by distorting a key relative price in the economy, the recent literature stresses the growth effects of the equilibrium real exchange rate itself, with the claim being that a depreciated equilibrium real exchange rate promotes economic growth. While there is no consensus on the precise channels through which this effect is generated, an increasingly common view in policy circles points to saving as the channel of transmission, with the claim that a depreciated real exchange rate raises the domestic saving rate - which in turn stimulates growth by increasing the rate of capital accumulation. This paper offers a preliminary exploration of this claim. Drawing from standard analytical models, stylized facts on saving and real exchange rates, and existing empirical research on saving determinants, the paper assesses the link between the real exchange rate and saving. Overall, the conclusion is that saving is unlikely to provide the mechanism through which the real exchange rate affects growth.

This paper presents a theoretical and empirical analysis of policies aimed at setting a more depreciated level of the real exchange rate. An intertemporal optimizing model suggests that, in the absence of changes in fiscal policy, a more depreciated level of the real exchange can only be attained temporarily. This can be achieved by means of higher inflation and/or higher real interest rates, depending on the degree of capital mobility. Evidence for Brazil, Chile, and Colombia supports the model’s prediction that undervalued real exchange rates are associated with higher inflation.

Increased attention is being paid to assessments of the actual values of countries' real exchange rates relative to their "equilibrium" values as suggested by "fundamental" determining factors. This paper assesses the robustness of alternative approaches and models commonly used to derive equilibrium real exchange rate estimates. Using China's currency to illustrate this analysis, the variance in estimates raises serious questions regarding how robust the results are. The basic conclusion from the tests used here is that, at least for China, small changes in model specifications, explanatory variable definitions, and time periods used in estimation can lead to very substantial differences in equilibrium real exchange rate estimates. Thus, such estimates should be treated with great caution.

In less than three decades, China has grown from playing a negligible role in international trade to being one of the world's largest exporters, a substantial importer of raw materials, intermediate outputs, and other goods, and both a recipient and source of foreign investment. Not surprisingly, China's economic dynamism has generated considerable attention and concern in the United States and beyond. While some analysts have warned of the potential pitfalls of China's rise—the loss of jobs, for example—others have highlighted the benefits of new market and investment opportunities for US firms. Bringing together an expert group of contributors, China's Growing Role in World Trade undertakes an empirical investigation of the effects of China's new status. The essays collected here provide detailed analyses of the microstructure of trade, the macroeconomic implications, sector-level issues, and foreign direct investment. This volume's careful examination of micro data in light of established economic theories clarifies a number of misconceptions, disproves some conventional wisdom, and documents data patterns that enhance our understanding of China's trade and what it may mean to the rest of the world.

This new collection revolves around Krugman's work on international monetary economics from the late 1970s to the present in an effort to make sense of a turbulent period that "involved one surprise after another, most of them unpleasant." Paul Krugman's first collection of essays, Rethinking International Trade, mounted a spirited assault on established trade theory and proposed an alternative approach to account for increasing returns and imperfect competition. Less theoretical and more embedded in real-world experience, this new collection revolves around Krugman's work on international monetary economics from the late 1970s to the present in an effort to make sense of a turbulent period that "involved one surprise after another, most of them unpleasant." The eleven essays cover such key areas as the role of exchange rates in balance-of-payments adjustment policy, the role of speculation in the functioning of exchange rate regimes, Third World debt, and the construction of an international monetary system. They are unified by the same basic methodology and style the construction of a small theoretical model in order to simplify or clarify a puzzling or difficult world monetary problem.

How successful is PPP, and its extension in the monetary model, as a measure of the equilibrium exchange rate? What are the determinants and dynamics of equilibrium real exchange rates? How can misalignments be measured, and what are their causes? What are the effects of specific policies upon the equilibrium exchange rate? The answers to these questions are important to academic theorists, policymakers, international bankers and investment fund managers. This volume encompasses all of the competing views of equilibrium exchange rate determination, from PPP, through other reduced form models, to the macroeconomic balance approach. This volume is essentially empirical: what do we know about exchange rates? The different econometric and theoretical approaches taken by the various authors in this volume lead to mutually consistent conclusions. This consistency gives us confidence that significant progress has been made in understanding what are the fundamental determinants of exchange rates and what are the forces operating to bring them back in line with the fundamentals.
