The response of an economy to a windfall of foreign exchange (be it aid or natural resource revenues) is often constrained by absorptive capacity. We provide a micro-founded analysis of absorption constraints, based on the idea that expanding the economy’s capital stock (in aggregate or...

This paper analyses and compares the effects of common demand and supply shocks on the setting of optimal monetary policies under a clean float, a managed exchange rate system (such as the EMS) and a monetary union, when welfare depends on unemployment and the cost of living. The results suggest...

A classical equilibrium model is analysed of two interdependent monetary economies in which it is assumed that cash is the only asset, and which is characterized by perfect foresight, flexible exchange rates and imperfect substitution between home and foreign goods. The first-best optimum sets...

It is shown that, when there is a genuine long-run trade-off between inflation and output, coordination under pre-commitment yields substantial improvements in economic welfare. The analysis is conducted within the context of a two-country model with capital accumulation, immobile labour,...

The development of the seven main OECD economies during the 1970s and 1980s is discussed. Subsequently, wage equations of the error-correction type for the seven largest OECD economies are estimated. The hypothesis of real wage rigidity cannot be rejected for the French, German, Italian and...

An adverse supply shock hits a two-country Mundell-Fleming world and causes unemployment and a higher cost of living. The optimal fiscal policies under noncooperative and under international policy coordination are then contrasted under three alternative regimes: floating exchange rates with...

This paper discuss the merits of an independent "EuroFed" within the context of a tax/seigniorage smoothing model for a monetary union. There is an incentive to use a surprise inflation tax to wipe out the real value of government debt and wage contracts because this allows a cut in...
