The paper proposes a way to measure the mechanical and psychological effects of majority runoff versus plurality. Building on a series of laboratory experiments on presidential-type elections, we evaluate these effects with respect to the probability of election of a centrist candidate. In our...

[fre] La norme majoritaire. . Une correspondance de choix définit, en fonction des préférences individuelles, un choix unique, ou un ensemble de choix possibles. On modélise ainsi des règles de décisions, comme la règle de Borda ou la règle de Kemeny-Young, ainsi que des critères de...

Nous rendons compte d'une série d'expériences de laboratoire à propos des comportements de vote. Dans une situation où les sujets ont des préférences unimodales nous observons que le vote à un tour et le vote à deux tours génèrent des effets significatifs de dépendance du chemin,...

This paper presents the experimental results of a “Transcontinental Ultimatum Game” implemented between India and France. We use a standard ultimatum game, but in one treatment Indian subjects made offers to French subjects (ItoF treatment) and, in another treatment, French subjects made...

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...

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...
