Social identity and voting behavior

This paper uses the unique social structure of Arab communities to examine the effect of social identity on voter turnout. We first show that voters are more likely to vote for a candidate who shares their social group (signified by last name) as compared to other candidates. Using last name as a measure of group affiliation, an inverted U-shaped relationship between group size and voter turnout has been found (borderline significant) which is consistent with theoretical models that reconcile the paradox of voting by incorporating group behavior.
