Protectionist policies have often relevant effects at the regional level. This paper analyzes the impact of sugar import duties on emigration in nineteenth century Italy. Both for climatic reasons and the nature of the soil, the cultivation and processing of sugar beets was geographically concentrated. Our theoretical model illustrates how a tariff that favours local producers may affect residents' incentives to migrate abroad. Using a new set historical data, the predictions of the model are tested through quasi‐experimental methods which use the exogenous variation in sugar cultivation across areas to estimate the effect of interest. Results show that protectionism reduced the relative incentive to migrate away from sugar‐producing areas. [ABSTRACT FROM AUTHOR]

This paper examines the effect of international mobility on the education‐job mismatch and skill‐mismatch of PhD graduates after controlling for self‐selection into cross‐border mobility. Using individual‐level data from two waves of surveys of PhD recipients in Italy conducted by the Italian National Institute of Statistics, we find that migration to foreign countries reduces significantly the risk of overeducation and overskilling. These results remain robust to different empirical methodologies and subsamples. [ABSTRACT FROM AUTHOR]
