The paper proposes a way to measure mechanical and psychological effects of majority runoff versus plurality electoral systems in candidate elections. Building on a series of laboratory experiments, we evaluate these effects with respect to the probability of electing a Condorcet winner...

L’objet de cet article est d’examiner, à la lumière de deux solutions majeures de la théorie des jeux coopératifs, les coalitions/négociations électorales qui ont lieu dans le cas où le mode de scrutin est un scrutin proportionnel avec listes bloquées, prime au gagnant et comportant...

We report on laboratory experiments on voting. In a setting where subjects have single-peaked preferences we find that the rational choice theory provides very good predictions of actual individual behavior in one-round and approval voting elections, but fares poorly in explaining vote choice...

This paper proposes a game to study strategic communication on platforms by parties. Parties’ platforms have been chosen in a multidimensional policy space, but are imperfectly known by voters. Parties strategically decide the emphasis they put on the various issues, and thus the precision of...

We study the role of status in an experimental Principal-Agent game.Status is awarded to subjects based on either talent or luck. In each randomly matched principal-agent pair, the principal chooses the agent's status-contingent piece rate for a task in which talent matters for performance (an...

We analyze how uncertainty regarding future climate conditions affects the design of concession contracts, organizational forms and technological choices in a principal-agent context with dynamic moral hazard, limited liability and irreversibility constraints. The prospect of future, uncertain...

In 2008, an opposition coalition defeated the Paraguayan Colorado Party, which had been in power for 61 years, including 35 years of the longest dictatorship in South America. Using data of all the public procurement transactions from 2004 through 2011 and the political connections of the 700...
