The European Union has increasingly integrated since World War II to the point where most European countries now share a currency and have freedom of movement for travelers and workers. This has created asymmetries in the European economy because of reports and studies that have found a low labor mobility, which is a requirement of a common currency area. This paper uses an econometric model and the theory of optimum currency areas to look at whether what language grouping a migrant is from affects his or her migration decision. The paper also looks at what an inflexible labor market may mean for European Central Bank policymakers and the macroeconomic outlook of the eurozone.
