A cash lottery increases voter turnout

Reform efforts to improve turnout typically focus on reducing the costs of participation or strengthening appeals to civic duty. While these efforts generate modest effects, this paper explores whether citizens might respond to extrinsic rewards to encourage voting. We conduct a field experiment offering lottery prizes to undergraduate students in conjunction with a student government election at a major public university. We find that extrinsic rewards appear to boost voting significantly in these low turnout elections and that the effects of a lottery appear to be especially strong among those of lower socio-economic status.
