Abstract
Using a calibrated two-bloc endogenous growth model of the European economy, we assess the growth and welfare impact of East-West European migration of different skill compositions. The East has a lower total factor productivity and a lower endowment of skilled labour. Migration can induce two growth-enhancing effects: an efficiency effect from the more e±cient use of labour in the West and a sectoral reallocation effect from a fall in the Western skilled-unskilled wage rates. Despite growth gains there are both winners (migrants, the representative Western non-migrant household) and losers (the representative Eastern household remaining). Remittances can see the latter group joining the winners.
