The concept of the Condorcet winner has become central to most electoral models in the political economy literature. A Condorcet winner is the alternative preferred by a plurality in every pairwise competition; the notion of a k-winner generalizes that of a Condorcet winner. The k-winner is the...

"Pendular Voting" presents a novel two-stage voting procedure: A randomly chosen citizen group votes on a proposal replacing the status quo. Depending on the outcome, a "counterproposal" ensues, that is closer to/further away from the status quo than the original proposal. All citizens vote...

Can an ethically justifiable decision-making process be facilitated through a machine moral agent in the form of advice? The premise revolves around decision votes explicitly solicited from human individuals and based on scenarios such as the Trolley Problem, reflected in data and processed...

We present simple and direct arguments to characterize strongly group strategy-proof social choice functions whose range is of cardinality two. The underlying society is of arbitrary cardinality, and agents can be indifferent among alternatives.

Majority voting is considered an efficient information aggregation mechanism in committee decision-making. We examine if this holds in environments where voters first need to acquire information from sources of varied quality and cost. In such environments, efficiency may depend on free-riding...

We theoretically investigate how the application of unanimity rule can lead to inefficient delay in collective decision making. We do so in the context of a distributive multilateral bargaining model featuring strategic pre-commitment. Prior to each bargaining round, players can declare a...

I analyze Dutch panel data that contains rich information on voting, political opinions, and personality traits. I show that "adversarial" preferences - competitiveness, negative reciprocity, distrust, and selfishness - are strong predictors of right-wing and populist political preferences....

Bouton et al. (2022) compare the properties of majority run-off and plurality rule elections in a laboratory setting, focusing on Duverger's prediction that plurality rule leads to higher levels of strategic voting. They produce a causal estimate of the difference in incidence of strategic...

The debate in the European Union (EU) on the expansion of majority decision-making is entering a new round. Germany, in particular, is seeking to build a coalition in favour of more majority decisions in light of the, at times, difficult decision-making process concerning foreign and security...
