List Experiments, Political Sophistication, and Vote Buying: Experimental Evidence from Mexico

Abstract

This research conducted list experiments to estimate the percentage of respondents who received electoral gifts during the 2015 legislative and the 2015 and 2017 subnational campaigns in Mexico. Consistent with recent studies on sensitive survey techniques, our research finds that list experiments seem to methodologically work better among more sophisticated voters (e.g. those with higher levels of education). Such findings suggest that previous studies that rely on list experiments tend to underestimate the percentage of voters who receive electoral gifts since this technique tends to work better among respondents who are, in fact, least likely to be targeted by clientelistic strategies. Given levels of education in the region, we suggest that research solely relying on list experiments approach its empirical findings with caution.
