Referenda on Hosting the Olympics: What Drives Voter Turnout?

Public referenda have recently put an end to the ambitions of several cities to host the Olympic Games. The outcome of referenda depends on two major decisions: a content decision whether to support hosting the Olympics and a turnout decision whether or not to cast a vote. Unlike the content decision, the turnout decision has received little attention in sports economics, even though it can distort the outcome of a referendum, lead to a misrepresentation of minorities, and reduce the acceptance of referendum results. We therefore examine the determinants of turnout at Olympic referenda using a population-representative data set from 12 democratic countries. Our findings suggest a nonlinear and robust relationship between individual support and voter turnout
