In 2008, Sweden introduced a non-selective labour migration policy without labour market tests and human capital considerations. This article studies the effects of the policy change on the size, composition and labour market outcomes. Using longitudinal register data, we find that the 2008 liberalizations of the Swedish labour migration policy increased the number of labour migrants from non-EU countries. Post-reform labour migrant cohorts have on average lower level of human capital, and the lower level of human capital translates into worse labour market outcomes. One year after migration, post-reform cohorts have a higher skills-mismatch and about 30 percent lower income. Migration controls against abuse introduced in 2011 and 2012 improved the labour market outcomes somewhat.
