The Impact of Social Mobility and Within-Family Learning on Voter Preferences

Abstract: Income-maximizing consumers should vote in predictable ways: support for liberal, redistributive governments should fall as income rises. But weak empirical evidence for these voting patterns might suggest that voters are influenced by perceptions of social mobility from within-family learning, or expectations regarding future income dynamics. To examine these effects, this paper uses two different data sources, including new information from a data set of twins. Little evidence is found to suggest that expectations of future upward mobility alter voting preferences, but a new econometric approach shows that within-family learning and family-specific effects are quite important determinants of voting preferences.
