We consider a framework where the optimal decision rule determining the collective choice depends in a simple way on the decision makers’ posterior probabilities of a particular state of nature. Nevertheless, voting is generally an inefficient way to make collective choices and this paper...

We compiled data on all United Nations General Assembly resolutions on which voting took place between January 1990 and June 2013 and find a preoccupation with one country: in 65 percent of instances in which a country is criticized in a resolution, the country is Israel, with no other country...

We study the role of self-interest and social preferences in referenda. Our analysis is based on collective purchasing decisions of university students on deep-discount flat rate tickets for public transportation and culture. Individual usage data allows quantifying monetary benefits associated...

We examine whether conservative politicians are less likely to support same-sex marriage when they run for office in safe districts using new data based on a roll-call vote in the national German parliament. The results show that the margin of the majority for the incumbent in the previous...

Geographic representation is an important consideration in candidate nominations, even under closed-list proportional representation (PR), and may even matter for distributive policy outcomes. However, since nominations are determined strategically, the causal effects of local representation are...

The direct democratic choice of an examination standard, i.e., a performance level required to graduate, is evaluated against a utilitarian welfare function. It is shown that the median preferred standard is inefficiently low if the marginal cost of reaching a higher performance reacts more...

How do electoral rules affect the representation of women? We collect panel data on the universe of Italian politicians from all levels of government over the period 1987-2013 and obtain a complete picture of the career paths of male and female politicians across the whole arc of their careers...

We compare single ballot vs dual ballot elections under plurality rule, assuming sincere voting and allowing for partly endogenous party formation. Under the dual ballot, the number of parties is larger but the influence of extremist voters on equilibrium policy is smaller, because their...
