Two-round elections, one-round determinants? Evidence from the French municipal elections

Abstract

Using a new database of French municipalities that covers 821 towns and two elections (2001 and 2008), we examine how the budget structure, degree of electoral competition and the economic context affect the share of votes for the incumbent. We take into account the institutional details of the two-round structure of the electoral process created by French electoral rules (dual ballot under plurality rules). We show that in the first round of the electoral process, spending on equipment (including infrastructures) can influence the voter, and that electoral competition has a strong impact on the incumbent’s score. In the second round, the incumbent’s vote is affected more by national considerations and local budget variables have no effect. We show that the dynamics between the first and the second rounds are intense. The results suggest that the determinants of each round’s outcome in a two-round electoral process are different.
