Unconditional cash transfers & voter turnout
利用阿拉斯加永久基金分红这一大规模自然实验，研究发现选举前一个月发放的现金支票金额越大，选民投票率越高，尤其是州长选举中现金增加10%（190美元）使投票率提高1.4个百分点，效果集中在年轻和低收入群体，机制是降低了选民冷漠。
Abstract We estimate the effect of unconditional cash transfers on voter turnout, leveraging a large‐scale natural experiment, the Alaska Permanent Fund Dividend (PFD) program, which has provided residents with a check of varying size 1 month before election day since 1982. We find that larger transfers cause people to vote, especially in gubernatorial elections in which a 10% increase in cash ($190) causes a 1.4 percentage point increase in turnout. Effects are concentrated among the young and poor. Survey data suggests the mechanism is reduced voter apathy. Implications are discussed.
