New Labour? The Effects of Migration from Central and Eastern Europe on Unemployment and Wages in the UK

摘要

The UK was one of only three countries that granted free movement of workers to accession nationals following the enlargement of the European Union in May 2004. The resulting migration inflow, which was substantially larger and faster than anticipated, arguably corresponds more closely to an exogenous supply shock than most migration shocks studied in the literature. We evaluate the impact of this migration inflow - one of the largest in British history - on the UK labour market. We use new monthly micro-level data and an empirical approach that investigates which of several particular labour markets in the UK - with varying degrees of natives' mobility and migrants' self-selection may have been affected. We found little evidence that the inflow of accession migrants contributed to a fall in wages or a rise in claimant unemployment in the UK between 2004 and 2006.
