Monetary policy affects the ... of goods and assets and (iii) effects through changes in explicit or implicit real interest rates on aggregate demand. - Rudi Dornbusch

If there was ever a bad idea, EMU it is.

The paper develops a simple macroeconomic framework for the study of exchange rate movements. The purpose is to develop a theory that is suggestive of the observed large fluctuations in exchange rates while at the same time establishing that such exchange rate movements are consistent with rational expectations formation. In developing a formal model we draw on the role of asset markets, capital mobility, and expectations that have been emphasized in recent literature.

The most serious criticism of EMU is that by abandoning exchange rate adjustments it transfers to the labor market the task of adjusting for competitiveness and relative prices... losses in output and employment (and pressure on the European central bank to inflate) will predominate.
