Policy Feedback and Voter Turnout: Evidence from the Finnish Basic Income Experiment

In many democracies, unemployed and low-income citizens are less willing to vote. Can social policies weaken the link between income and turnout? We study policy feedback leveraging a unique experiment in Finland, which randomly assigned a sizable group of unemployed to receiving an unconditional basic income for two years (2017-19). Combining individual-level registry and survey data, we show that the intervention has large positive effects on voter turnout. Unconditional basic income increases turnout in municipal elections by about 3 p.p., on average, an effect that is concentrated among marginal voters (+ 6-8 p.p.) and persists in national elections after the end of the experiment. Exploring possible mechanisms, our analysis highlights the role of the interpretive effects that follow from unconditionality in the bureaucratic process, including higher levels of political trust and efficacy. We discuss implications for theories of voter turnout and policy feedback, and the design of basic income policies.
