The common use of majority rule in group decision making is puzzling. In theory, it inequitably favors the proposer, and paradoxically, it disadvantages voters further if they are inequity averse. In practice, however, outcomes are equitable. The present paper analyzes data from a novel...

We experimentally study behavior in a simple voting game where players have private information about their preferences. With random matching, subjects overwhelmingly follow the dominant strategy to exaggerate their preferences, which leads to inefficiency. We analyze an exogenous linking...

This paper investigates - in a large heterogeneous sample - the relationship between social preferences on the one hand, and socioeconomic factors and political preferences on the other hand. Socioeconomic factors correlate with social preferences, and social preferences robustly shape political...

There are many situations in which different groups make collective decisions by committee voting, with each group represented by a single person. A natural question is what voting system such a committee should use. Concepts based on voting power provide guidelines for this choice. The two most...

A conclave is a voting mechanism in which a committee selects an alternative by voting until a sufficient supermajority is reached. We study experimentally welfare properties of simple three-voter conclaves with privately known preferences over two outcomes and waiting costs. The resulting game...

The burgeoning literature on the use of sanctions to support public goods provision has largely neglected the use of formal or centralized sanctions. We let subjects playing a linear public goods game vote on the parameters of a formal sanction scheme capable both of resolving and of...

We test the theory of expressive voting in relation to political ideology in a laboratory experiment. After deriving our hypotheses from a decision theoretic model, we examine voting decisions in an experiment in which we use the size of the electorate as the treatment variable. Using a Heckman...

The burgeoning literature on the use of sanctions to support public goods provision has largely neglected the use of formal or centralized sanctions. We let subjects playing a linear public goods game vote on the parameters of a formal sanction scheme capable both of resolving and of...

This paper analyzes the role of narrowly selfish and other-regarding preferences for the median voter in a Meltzer-Richard (1981) framework. We use computerized and real human co-players to distinguish between these sets of motivations. Redistribution to real co-players has a negative effect on...

This paper analyzes responsibility attributions for outcomes of collective decision making processes. In particular, we ask if decision makers are blamed for being pivotal if they implement an unpopular outcome in a sequential voting process. We conduct an experimental voting game in which...
