Aggregate Fluctuations and International Migration
研究了商业周期和就业率变化等短期因素如何影响国际移民流动，发现总体波动和就业率都会影响移民，且申根协定和欧元显著增加了成员国间的劳动力流动。
Abstract In this paper, we study the role of short‐run factors such as business cycles or changes in employment rates in explaining international migration flows. First, we derive a model of optimal migration choice predicting that short‐run economic fluctuations trigger migration flows on top of the impact exerted by long‐run factors. Second, we empirically test the magnitude of the effect of these short‐run factors on migration flows. Our results indicate that both aggregate fluctuations and employment rates affect migration flows. Third, we provide evidence that the Schengen Agreement and the euro significantly increased the international mobility of workers between the member countries.uuuü
