We investigate experimentally whether entry costs have an impact on the evolutionof cooperation in a social dilemma game. In particular, subjects repeatedly playthe so-called takeover game with anonymous partners randomly drawn from a fixedpopulation of participants. The game represents a social...

Erat and Gneezy (2012) conduct an experiment to test whether people avoid lying in a situation where doing so would lead to a Pareto improvement. They conclude that many people exhibit such a "pure lie aversion." I argue that the experiment does not provide a reliable test for such an aversion,...

In experiments which measure subjects' beliefs, both beliefs about others' behavior and beliefs about others' beliefs, are often correlated with a subject's own choices. Such phenomena have been interpreted as evidence of a causal relationship between beliefs and behavior. An alternative...

Arguably the most important campaign finance regulations in U.S. federal elections are limitsimposed on the amount that an individual or organization may donate to a federal campaign. Suchcontribution limits are advocated on two separate grounds. The first is that they prevent corruption,the...

We consider a committee facing binary decisions on a number of proposals. If members vote sincerely and payoffs are symmetric in expectation, it can be shown that the simple majority rule is the best q-majority rule in an aggregate or expected payoff sense. We argue that this conclusion changes...

We report an experiment on the Probabilistic Serial (PS) mechanism for allocating indivisible goods. The PS mechanism, a recently discovered alternative to the widely used Random Serial Dictatorship mechanism, has attractive fairness and efficiency properties if people report their preferences...

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...
