α: calibrated so average coauthorship-adjusted count equals average raw count
One of the macro variables that are included in most models is the exchange rate. Overall performance of a country's exchange rate is measured by changes in nominal or real effective exchange rate (REER). These rates are constructed and published mostly for industrial countries by international organizations. Less developed countries have received little attention. In this article, the two rates are constructed for 21 African countries using quarterly data over the period 1971Q1--2012Q4. As an application, we use the REERs to show that even in Africa the movements of the real effective rates follow a nonlinear path.
