公共支出配置的需求侧决定因素：选民信任、风险与时间偏好

We examine whether public spending misallocations may reflect voter demand factors such as political and interpersonal trust or risk and time preferences. A model of voter preferences over public spending tradeoffs provides individual-level testable hypotheses. The data come from an original survey that offered voters in seven Latin American countries binary choices between public spending options in education and security. Respondents with higher mistrust or impatience are more likely to choose transfers over public goods; more impatient respondents are also more likely to choose short-term spending over public investment. Within public goods, however, political mistrust and risk aversion can shift voter demand from current to investment spending. Randomized experiments providing information about the benefits of public investment have the expected average demand impacts, while respondents with high political mistrust or impatience show attenuated treatment effects.
