Parallel Exchange Rates In Developing Countries Lessons From Eight Case Studies

'...the most definitive study of the subject, assembling an all-star cast to address the many outstanding questions and succeeding beyond expectations in combining elegant theory and state of the art econometrics to reach very sensible policy conclusions.' - Mohsin S. Khan, Deputy Director, Research Department, International Monetary Fund ' This book fills an important vacuum in the literature of the economic consequences of parallel markets and should prove of great value to students of economic development and to policy-makers in developing countries as they struggle to reform their exchange rate and trade incentive systems. Here they will find all that they need to know.' - Vittorio Corbo, Professor of Economics, Universidad Catolica de Chile 'A most comprehensive treatment of the relationships between parallel foreign exchange markets and macroeconomic policies, both across countries and over time. The book substantially enhances our understanding of how these systems work in practice and will be of great interest to policy-makers, researchers and graduate students of economic policy.' - Samuel M. Wangwe, Professor of Economics, University of Dar es Salaam and Executive Director, Economic and Social Research Foundation, Dar es Salaam, Tanzania This book examines extensive empirical evidence on the macroeconomic implications of parallel exchange rates in developing countries. Eight case-studies from Africa, Latin America, and Turkey provide detailed evidence on the emergence of parallel exchange rates, their impact on macroeconomic performance, and the criteria for successful exchange-rate unification. A chapter on European dual exchange rates summarizes the contrasting experience of industrial countries. An overview chapter lays out the analytical framework, assesses the evidence, and draws policy conclusions.

The paper reviews recent theoretical and empirical developments in the analysis of informal currency markets in developing countries. The basic characteristics of these markets are highlighted, and alternative analytical models to explain them are discussed. The implications for exchange rate policy —including imposition of foreign exchange restrictions, devaluation, and unification of exchange markets— in countries with a sizable parallel market are also examined.

Some central banks have maintained overvalued official exchange rates, while unable to ensure that supply of foreign exchange meets legitimate demand for current account transactions at that price. A parallel exchange rate market develops, in such circumstances; and when the spread between the official and parallel rates is both substantial and sustained, price levels in the economy typically reflect the parallel market exchange rate. “Recognizing reality” by allowing economic agents to use a market clearing rate benefits economic activity without necessarily leading to more inflation. But a unified, market-clearing exchange rate will not stabilize without a supportive fiscal and monetary context. A number of country case studies are included; my thanks to Jie Ren for pulling together all the data for the country case studies, and the production of the charts.

The paper develops and tests a model of a developing economy that incorporates trade and capital restrictions, illegal transactions, a parallel foreign exchange market, currency substitution features, and forward-looking rational expectations. Temporary expansionary demand policies are associated with an increase in output and prices, a fall in the stock of net foreign assets, and a depreciation of the parallel exchange rate. The speed of adjustment is inversely related to the degree of rationing in the official foreign currency market. A once-for–all devaluation of the official exchange rate has no long-term effect on the premium.

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.

Many sub-Saharan African (SSA) countries liberalized their economies in the 1980s and early 1990s. This paper reviews the foreign exchange regime reforms in selected SSA, and their associated macroeconomic policies and economic performance during and after these reforms were undertaken. Before liberalization, most of the reviewed countries were characterized by extensive foreign exchange rationing, sizeable black market premiums, and declining per capita real income. Today, the countries that successfully reformed look markedly different. Rationing and parallel market spreads are a distant memory, and per capita income has increased sharply.
