This paper estimates the impact of cohort size on wages using data on young males in European regions covering 2004-2010. The effect of cohort size on wages is identified through an instrumental variables strategy which, in contrast to previous analyses of European data, addresses self-selection into geographical areas as well as into educational groups. The results suggest that cohort size has a significant negative effect on male wages for individuals with secondary education – the largest group – but not for individuals with less than secondary education or tertiary education. This effect is underestimated if self-selection into geographical areas is not addressed.
