Using estimates that currency unions double trade, we quantify the welfare effects of forming currency unions for the African regional economic communities and for the African Union as a whole. The potential increase in trade is shown to be small, and much less than that resulting from the...

The paper presents estimates of a model of the credibility of the U.K. commitment to its central parity against the deutsche mark during the period of U.K. ERM membership (1990-92). The measure of credibility used is the long-term interest differential with Germany. Credibility is decomposed...

The economic effects of German unification are first discussed in the context of a global saving/investment model. Next, simulations of MULTIMOD are presented, suggesting for the FRG an initial increase in long-term real interest rates equal to 3/4 of a percentage point, increased output, a...

Stage 2 of monetary union in the Europe is to involve greater monetary cooperation; the paper examines the case for using the M3 money supply aggregated across “core ERM” countries- -those with low inflation and absence of realignments- -as a vehicle for that cooperation. First, the...
