Migration, Production Structure and Exports

摘要: In this paper we study the effect of migration in a two-sector model where production is performed with one freely mobile factor and sector-specific CES composites two labor services -- simple complex tasks. Tasks' supply provided by migrants natives; they differ terms productivity performing different The shows that an inflow has on structure favor sector uses more intensively tasks like manufacturing spirit Rybczynski effect. Owners gains from immigration real nominal terms.We take advantage detailed data set migrants' work permits at provincial level (NUTS3) Italy to assess inflows export Italian provinces 1995-2006. When assuming service relatively intensive rather than respect sector, our theoretical confirmed data. Although investigated time span very short, small but statistically significant: 10% increase ratio foreign-born residents province population induces 0.5% manufactures' value added services' added. same pattern much stronger share 2.2% relative low-tech exports (with high-tech exports).
