This paper develops a welfare-based model of monetary policy in an open economy. We focus on the extent to which monetary policy should be employed in maintaining the exchange rate. The traditional approach maintains that exchange rate flexibility is desirable in the presence of real...

We examine proposals to introduce in the European Community national insurance against unevenly distributed shocks. This would operate differently from tax and government spending activities that now yield regional insurance within countries, since the latter are mainly designed for other...
