Real Exchange Rate Targeting And Macroeconomic Instability

Using an optimizing model of a small open economy, this paper studies the macroeconomic effects of PPP rules whereby the government increases the devaluation rate when the real exchange rate defined as the price of tradables in terms of nontradables is below its long-run level and reduces the devaluation rate when the real exchange rate is above its long-run level. The paper shows that the mere existence of such a rule can generate aggregate fluctuations due to self-fulfilling revisions in expectations. The result is shown to obtain in both flexible- and sticky-price environments.

We analyze coordination of monetary and exchange rate policy in a two-sector model of a small open economy featuring imperfect substitution between domestic and foreign financial assets. Our central finding is that management of the exchange rate greatly enhances the efficacy of inflation targeting. In a flexible exchange rate system, inflation targeting incurs a high risk of indeterminacy where macroeconomic fluctuations can be driven by self-fulfilling expectations. Moreover, small inflation shocks may escalate into much larger increases in inflation ex post. Both problems disappear when the central bank leans heavily against the wind in a managed float.

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.

Inflation targeting (IT) has become the sacred cow of central banking. But its suitability to developing nations remains contested. The contributors to this volume perform the valuable service of sketching out plausible, more development-friendly alternatives. They are to be commended in particular for avoiding a one-size-fits-all approach and paying close attention to the needs of specific countries. Their proposals range from relatively minor tinkering in IT to comprehensive overhaul. A common theme is the central role of the real exchange rate, which the central banks ignore at their economies peril. Dani Rodrik, Harvard University, US As the world economy is devastated by a virulent financial crisis and jobs are lost in scores, central bankers are increasingly questioned as to why they have failed to sustain stability and growth even though they told us all along that conquering inflation would be necessary and sufficient to do so while hoping to get a pat on the back for achieving a degree of price stability unprecedented in recent times. This book provides a lot of food for thought on why. It is a powerful critique of the orthodox obsession with inflation in neglect of the two deepseated problems of the unbridled market economy financial instability and unemployment. It is a must for all policy makers, notably in the developing world, and for the mainstream. Yilmaz Akyuz, formerly of the United Nations Conference on Trade and Development, Geneva, Switzerland This collective volume makes a compelling case for balancing the developmental and stabilization functions of central banks. In particular, the authors emphasize that, as practiced in many successful developing countries, competitive real exchange rates can be good for growth and employment generation, and should thus be a specific focus of central bank actions. The book is a must read for those looking for a more balanced framework for central bank policies. José Antonio Ocampo, Columbia University, US and former Under-Secretary-General of the United Nations for Economic and Social Affairs and Finance Minister of Colombia This book, written by an international team of economists, develops concrete, country specific alternatives to inflation targeting, the dominant policy framework of central bank policy that focuses on keeping inflation in the low single digits to the virtual exclusion of other key goals such as employment creation, poverty reduction and sustainable development. The book includes thematic chapters, including analyses of class attitudes toward inflation and unemployment and the gender impacts of restrictive monetary policy. Other chapters propose improved monetary frameworks for Argentina, Brazil, India, Mexico, the Philippines, South Africa, Turkey, and Vietnam. Policy frameworks that are explored include employment targeting, and targeting a stable and competitive real exchange rate. The authors also show that to reach a larger number of targets, including higher employment and stable inflation, central banks must use a larger number of instruments, including capital management techniques. This volume offers concrete, socially valuable alternatives that economists, policy makers, students and interested laypeople should consider before adopting one size fits all, often inadequate, policies that have become a virtual policy making fad.

Foreign exchange intervention is frequently being used by central banks in countries which have a floating exchange rate. Most theoretical monetary policy models, however, do not take this phenomenon into account. This book contributes to close this gap between theory and practice by interpreting foreign exchange intervention as an additional monetary policy instrument for inflation targeting central banks. In-depth empirical analyses of the foreign exchange operations and interest rate policy of five inflation targeting countries (Australia, Canada, New Zealand, Sweden and the United Kingdom) demonstrate how foreign exchange intervention is used in practice.

This analysis of macroeconomic policy, originally published in 1989, argues that key government objectives, such as reduced inflation, decreased unemployment and an adequate level of national saving can be achieved only by employing both monetary and fiscal policies, in conjunction with supply-side policies expressly designed to improve the workings of the labour market. Part 1 is a comparative analysis showing the effects of monetary and fiscal policy on the economy. Real-wage rigidity in the labour market is shown to have important consequences for the working of both types of policy, because it conditions the economy’s response to tax changes. Part 2 presents an econometric model which combines consistent stock-flow accounts with a full range of expectational effects. Part 3 presents an innovative technique for solving rational expectations models with the need for arbitary terminal conditions.

A growing number of countries are anchoring their monetary policy through explicit inflation targeting. This policy has already scored remarkable successes in several countries, establishing central bank credibility, and reining in inflation where it had long been stubbornly high. But implementing inflation targets raises many difficult questions. What prerequisites must an economy and its institutions meet for the strategy to work? What choices should central banks make from the menu of possible variations on the basic approach? This book summarizes the discussions in a seminar at which economists and policymakers from ten countries reviewed their experiences with inflation targeting.

This paper studies the evolution of the exchange rates of sub-Saharan African currencies in the context of the global financial crisis. In particular, it analyzes the reasons behind the differences in the magnitude and volatility of the exchange rates among countries. To this end, it takes a sample of seven countries, four members of the East African Community (EAC) (Kenya, Rwanda, Tanzania, and Uganda), and three others, which experienced large exchange rate losses at the onset of the crisis: Ghana, Nigeria, and Zambia. First, it analyzes the movements of the exchange rates with respect to the U.S. dollar and two other major currencies. Second, it tries to link the magnitude of their movements to key factors, relating to the external environment and the countries' internal policies.

Combining thorough scholarship with illuminating real-world examples, this edited collection provides insights on the causes and consequences of movements in both exchange rates and external assets and has a strong focus on the policy implications of operating in an open economy, particularly the choice of exchange rate and monetary policy, exchange rate intervention and policies on capital mobility.
