Voting Technology, Political Responsiveness, and Infant Health: Evidence From Brazil

This paper studies the effects of an electronic voting technology that introduced visual aids in Brazilian elections and facilitated voting for the less educated. Estimates exploiting a regression discontinuity design embedded in its phase-in through time indicate that electronic voting reduced residual (error-ridden and uncounted) votes and generated the de facto enfranchisement of a large fraction (11%) of the electorate. This enhanced political participation of less educated (poorer) voters is then shown to have: (1) increased the number of state legislators that are themselves less educated; and (2) shifted government spending towards public health care, a policy that is particularly beneficial to the poor; leading to (3) improved health services utilization (pre-natal visits) by less educated mothers and (4) reduced occurrence of low-weight births in this group. No effects on health care utilization by more educated mothers and on the weight of their newborns are found. The results are consistent with the predictions of political economy models and demonstrate that electronic voting can promote the political empowerment of the poor and raise their living standards.
