Is the Euro Working? The Euro and European Labour Markets

TLDR: This paper showed that the euro zone still falls short as an optimal currency area in most respects, and that a "rigidity trap" has developed in the euro area, consisting of relatively tight monetary policy, forced fiscal consolidation, and a risk of deflation in some economies.

Abstract: Now that time has passed since the introduction of the euro as a commercial currency, it is possible to assess many arguments made in the abstract during the I99OS about European monetary union. This article shows that the euro zone still falls short as an optimal currency area in most respects. In particular, it undertakes an empirical analysis of the labour market and finds no progress toward flexibility or integration. These results challenge assertions of 'endogenous currency area' proponents that the euro area would become optimal 'after the fact', and that labour markets would serve as the principal avenue of adjustment. Instead, a 'rigidity trap' has developed in the euro area, consisting of relatively tight monetary policy, forced fiscal consolidation, and a risk of deflation in some economies. These conditions have compounded the difficulties of structural adjustment in European labour markets.
