Assistant Professor of Business Administration

Vincent Pons is an assistant professor of business administration in the Business, Government, and International Economy Unit, a Faculty Research Fellow at the National Bureau of Economic Research (NBER), and a faculty affiliate at the Abdul Latif Jameel Poverty Action Lab (J-PAL). He studies questions in political economy and development.

Professor Pons’s research studies the mechanisms through which representative democracy aggregates citizens’ preferences to understand why it can fail to deliver leaders, policies, and economic outcomes aligned with these preferences. This work has appeared in journals such as Econometrica, the American Economic Review and the American Political Science Review. It has resulted in mentions and opinion pieces in media outlets including Le Monde, The Huffington Post, and Slate. In his development research, he concentrates on health systems and policies.

Professor Pons received his PhD in economics from the Massachusetts Institute of Technology. He also holds a master in economics from the Ecole Normale Supérieure in Paris (joint with the Paris School of Economics and ENSAE) and a master’s degree in political philosophy from Université Paris 1, Panthéon-Sorbonne.

Expressive Voting and Its Cost: Evidence from Runoffs with Two or Three Candidates

In French parliamentary and local elections, candidates ranked first and second in the first round automatically qualify for the second round, while a third candidate qualifies only when selected by more than 12.5% of registered citizens. Using a fuzzy RDD around this threshold, we find that the third candidate attracts both “switchers,” who would have voted for one of the top two candidates if she were not present, and “loyal” voters, who would have abstained. Switchers vote for the third candidate even when she is very unlikely to win. This disproportionately harms the candidate ideologically closest to her and causes his defeat in one fifth of the races. These results suggest that a large fraction of voters value voting expressively over behaving strategically to ensure the victory of their second best. We rationalize our findings by a model in which different types of voters trade off expressive and strategic motives.
Will a Five-Minute Discussion Change Your Mind? A Countrywide Experiment on Voter Choice in France

This paper provides the first estimate of the effect of door-to-door canvassing on actual electoral outcomes, via a countrywide experiment embedded in Francois Hollande’s campaign in the 2012 French presidential election. While existing experiments randomized door-to-door visits at the individual level, the scale of this campaign (five million doors knocked) enabled randomization by precinct, the level at which vote shares are recorded administratively. Visits did not affect turnout, but increased Hollande’s vote share in the first round and accounted for one fourth of his victory margin in the second. Visits’ impact persisted in later elections, suggesting a lasting persuasion effect.
Voter Registration Costs and Disenfranchisement: Experimental Evidence from France

A large-scale randomized experiment conducted during the 2012 French presidential and parliamentary elections shows that voter registration requirements have significant effects on turnout, resulting in unequal participation. We assigned 20,500 apartments to one control or six treatment groups that received canvassing visits providing either information about registration or help to register at home. While both types of visits increased registration, home registration visits had a higher impact than information-only visits, indicating that both information costs and administrative barriers impede registration. Home registration did not reduce turnout among those who would have registered anyway. On the contrary, citizens registered due to the visits became more interested in and knowledgeable about the elections as a result of being able to participate in them, and 93% voted at least once in 2012. The results suggest that easing registration requirements could substantially enhance political participation and interest while improving representation of all groups.
