| Africa has important initiatives to build regional currency areas and ultimately a single African currency. Calculations using a calibrated model show that the proposed monetary unions are unlikely to yield net economic benefits for all countries, suggesting that all-inclusive monetary unions are not incentive-compatible—even if trade doubles as a result of sharing a currency. Central banks are assumed not to be immune from pressures to finance governments. While a monetary union will to some extent dilute the influence of individual governments, countries that exhibit fiscal discipline would not want to join a monetary union with others that do not. Given the heterogeneity across countries, monetary unions could be selectively expanded but not encompass all countries in a region. |
