Voter Turnout and Political Rents

Is the decline in voter turnout an indicator of a worse health of a representative democracy? We build a simple probabilistic-voting model with endogenous turnout to address this question. We ?nd that a lower turnout caused by a higher cost of voting implies higher political rents. Contrarily, a lower turnout caused by a higher ideological mobility of voters or by a lower expressive bene?t of voting implies lower political rents. If voters have a civic-duty motive to vote which depends on the level of rents, multiple equilibria (a high-rents and a low-rents) can arise.
