The previous weeks have emphasized history and comparative statics in the development of a theory and policy mix where further integration is a good thing.

This week and next, we'll dwell on the theory of optimal currency areas, looking in detail at what macroeconomic properties two (or more) countries should exhibit before joining their currencies together. We'll see the effects of a common currency on wages in different countries, on migration patterns, and on inflation and unemployment as well as capital movement. Throughout we'll be looking at the data on the effects of 'ever closer union' from the OECD and other EU think tanks.
