The IMF Working Papers series is designed to make IMF staff research available to a wide audience. With nearly 300 released each year, working papers cover a wide range of theoretical and analytical topics, including balance of payments, monetary and fiscal issues, global liquidity, and national and international economic developments.
The paper develops an interpretation of volatile exchange rate movements in a dollarized economy with very high rates of inflation. Differences between the rate of inflation and currency depreciation (over- or undershooting of the exchange rate) are seen as a proxy for changes in the relative demand for domestic and foreign currency. A simple model is calibrated for the Democratic Republic of the Congo in the 1990s and is used to derive estimates of the rate of dollarization.
