The Electoral Consequences of International Migration in Sending Countries: Evidence from Central and Eastern Europe

This paper examines the political attributes of emigrants and how their departure affects the electoral outcomes in their home countries. I argue that emigrants are different from those who remain in their political preferences as well as economic attributes, such that large-scale emigration changes the distribution of voters in sending countries. Emigration can also directly affect the policy preferences of individuals who stay in their home countries. I test these arguments in seven Central and Eastern European countries, using individual-level surveys and region-level data on emigration and elections. To address potential endogeneity issues, I use instrumental variable analysis, leveraging the surge of Polish emigration to the United Kingdom after the EU enlargement. I find that emigrants from Central and Eastern Europe tend to be younger, highly educated, and politically more progressive and that the vote shares of far-right parties are larger in regions with higher emigration rates. Also, I find that exposure to large-scale emigration affects the vote choices of individuals who remain.
