This chapter focuses on the determinants of vote choice, which are crucial to assessing the heterogeneity on voters’ sensitivity to parties’ policy and non-policy offers. We provide evidence that ideological proximity, competence for managing the economy, distributive expectations, and connections to partisan networks shape electoral behavior in both countries. Subsequently, we introduce a utility function that models the weight that voters attach to the policy and non-policy determinants of their vote choice. We then present a model that estimate separate parameters for voters in each socioeconomic category. We show that richer voters care more about ideological distance in both countries, although Chilean voters allot more weight to this dimension than their Argentine counterparts. Whereas Chilean better-off voters value macroeconomic competence more than poorer voters, poorer Argentine voters care more about parties’ ability to manage the economy than their richer counterparts. Even for distributive expectations, we show different patterns across countries in terms of the weight assigned by poorer and richer voters to public-sector job expectations in their electoral decision, which are more salient for poorer Argentine voters and middle-class Chilean voters.
