Adjustment Investment And The Real Exchange Rate In Developing Countries

LDC adjustment packages Riccardo Faini and Jaime de Melo Developing countries have been hit by a fall in their terms of trade, high real interest rates on their external debt, and a drought in commercial lending from abroad. Their subsequent adjustment packages, often supported by loans from the IMF and World Bank, focused on a sharp real exchange rate depreciation to restore external balance and a host of microeconomic reforms to secure a simultaneous supply-side improvement. This paper examines the success of these ‘adjustment with growth' packages in a large sample of developing countries. We find these packages have been much more successful in LDCs which export manufactures than they have in those concentrating on primary exports (primarily low-income African countries); the latter have not resumed sustainable growth, and most of their external adjustment has arisen from expenditure reduction, not an increase in supply. The longer-term prospects for manufacturing exporters are also brighter: there we detect signs of increased efficiency and a smaller decline in investment than in primary exporters. But we also find that a high external debt burden and an unstable macroeconomic environment impede investment in all LDCs. In the longer term, adjustment with growth packages will succeed only if they are accompanied by a more stable macroeconomic environment and appropriate debt relief

Serven examines empirically the link between real exchange rate uncertainty and private investment in developing countries using a large cross country-time series data set. He builds a GARCH-based measure of real exchange rate volatility and finds that it has a strong negative impact on investment, after controlling for other standard investment determinants and taking into account their potential endogeneity. The impact of uncertainty is not uniform, however. There is some evidence of threshold effects, so that uncertainty only matters when it exceeds some critical level. In addition, the negative impact of real exchange rate uncertainty on investment is significantly larger in economies that are highly open and in those with less developed financial systems.

In spite of the attention paid exchange rates in recent economic debates on developing countries, relatively few studies have systematically analyzed in detail the various ramifications of exchange rate policy in these countries. In this new volume from the National Bureau of Economic Research, leading economists use rigorous models to tackle various exchange rate issues, while also illuminating policy implications that emerge from their analyses. The volume, divided into four main sections, addresses: the role of exchange rates in stabilization programs and the adjustment process; the importance of exchange rate policy during liberalization reform in developing countries; exchange rate problems relevant and unique to developing countries, illustrated by case studies; and the problems defining, measuring, and identifying determinants of real exchange rates. Authors of individual papers examine the relation between commercial policies and exchange rates, the role of exchange rate policy in stabilization programs, the effectiveness of devaluations as a policy tool, and the interaction between exchange rate terms of trade an capital flow. This research will not only prove crucial to our understanding of the role of exchange rates in developing countries, but will clearly set the standard for future work in the field.

We show that the response of firm-level investment to real exchange rate movements varies depending on the production structure of the economy. Firms in advanced economies and in emerging Asia increase investment when the domestic currency weakens, in line with the traditional Mundell-Fleming model. However, in other emerging market and developing economies, as well as some advanced economies with a low degree of structural economic complexity, corporate investment increases when the domestic currency strengthens. This result is consistent with Diaz Alejandro (1963)—in economies where capital goods are mostly imported, a stronger real exchange rate reduces investment costs for domestic firms.

This paper analyzes the impact of capital inflows and exchange rate flexibility on the real exchange rate in developing countries based on panel cointegration techniques. The results show that public and private flows are associated with a real exchange rate appreciation. Among private flows, portfolio investment has the highest appreciation effect-almost seven times that of foreign direct investment or bank loans-and private transfers have the lowest effect. Using a de facto measure of exchange rate flexibility, we find that a more flexible exchange rate helps to dampen appreciation of the real exchange rate stemming from capital inflows.

Abstract: Devarajan, Go, Page, Robinson, and Thierfelder argued that if aid is about the future and recipients are able to plan consumption and investment decisions optimally over time, then the potential problem of an aid-induced appreciation of the real exchange rate (Dutch disease) does not occur. In their paper, "Aid, Growth and Real Exchange Rate Dynamics," this key result is derived without requiring extreme assumptions or additional productivity story. The economic framework is a standard neoclassical growth model, based on the familiar Salter-Swan characterization of an open economy, with full dynamic savings and investment decisions. It does require that the model is fully dynamic in both savings and investment decisions. An important assumption is that aid should be predictable for intertemporal smoothing to take place. If aid volatility forces recipients to be constrained and myopic, Dutch disease problems become an issue.

This paper addresses analytical aspects of exchange rate policy and emphasizes the relationship among exchange rate flexibility, financial discipline, and international competitiveness.

The exchange rate is a crucial variable linking a nation's domestic economy to the international market. Thus choice of an exchange rate regime is a central component in the economic policy of developing countries and a key factor affecting economic growth. Historically, most developing nations have employed strict exchange rate controls and heavy protection of domestic industry-policies now thought to be at odds with sustainable and desirable rates of economic growth. By contrast, many East Asian nations maintained exchange rate regimes designed to achieve an attractive climate for exports and an "outer-oriented" development strategy. The result has been rapid and consistent economic growth over the past few decades. Changes in Exchange Rates in Rapidly Developing Countries explores the impact of such diverse exchange control regimes in both historical and regional contexts, focusing particular attention on East Asia. This comprehensive, carefully researched volume will surely become a standard reference for scholars and policymakers.
