McPherson, and Stephen D. Younger November 1994 This study draws lessons for exchange rate management in Sub- Saharan Africa (SSA) from the experience of four countries that have experimented over the past decade with a variety of partial reforms. The four countries are Ghana, Uganda, Zambia and Senegal, with Senegal serving as a proxy for the CFA franc zone of 14 countries in West Africa. Although focussing on SSA, the paper offers a good primer on exchange management in developing countries that USAID missions worldwide should find of interest. The report includes an e.camination of the historical origins of the exchange rate debate in SSA; a review of the principles of exchange rate management in developing countries; a discussion of transition issues involved in moving from a fixed to flexible exchange rate system; a review of alternative exchange rate management regimes; the country case studies on Ghana, Senegal, Uganda, and Zambia; a discussion of the current status of macroeconomic and exchange rate management in the 46 countries in SSA; a review of the conventional arguments against devaluation and commentary questioning these arguments; and conclusions and policy recommendations. The Appendix includes an empirical analysis of devaluatioi and inflation in SSA based on a simple model of devaluation and inflation. The study finds that: " the anglophone economies showed signs of emerging from balance of payments disequilibria only when the governments concerned abandoned efforts at administratively determining exchange rates and let the market decide; " donors that sought to broaden the scope of exchange rate management reform in the anglophone countries have become convinced of the desirability of short-cirruiting tortuous policy meanderings and moving rapidly to ma&ket-determined exchange rates; * for the CFA franc zone countries, though still bound by a fixed exchange rate vis-a-vis the French franc, the January 1994 devaluation of 50 percent was a direct, though tardy, response to market forces, and initial signs of renewed investment and growth are positive; and " attempts to dampen wide gyrations in exchange rates is justifiable, but requires a sophistication in management that many SSA central banks and finance ministries have forfeited by tolerating institutional deterioration.
