The impact of closeness on turnout: An empirical relation based on a study of a two-round ballot

Several methodological difficulties emerge from the empirical evaluation of the impact of closeness on turnout. The most critical resides in the use of the actual electoral results to assess the impact of closeness. Important doubt therefore remains with respect to the empirical validity of the relationship between turnout and closeness. This article intends to explore this ambiguity by an econometric analysis of the two-round French legislative elections. The first ballot gives excellent information to the voters on the expected closeness of the upcoming second ballot. The results show that closeness, whatever its measure, has an important and meaningful impact on electoral participation. Copyright Springer Science + Business Media, Inc. 2006
