The evidence from many experiments suggests that people are heterogeneous with regard to their abilities to make rational, forward looking, decisions. This raises the question when the rational types are decisive for aggregate outcomes and when the boundedly rational types shape aggregate...

The three-door problem is an astounding example of a systematic violation of a key rationality postulate. In this seemingly simple individual decision task, most people initially fail to correctly apply Bayes' Law, and to make the payoff-maximizing choice. Previous experimental studies have...

The three-door problem is an example of a systematic violation of a key rationality postulate that has attracted much attention. In this seemingly simple individual decision task, most people initially fail to apply correctly Bayes' Law, and to make the payoff-maximizing choice. Previous...

The ability of groups to implement efficiency-enhancing institutions is emerging as a central theme of research in economics. This paper explores voting on a scheme of intergroup competition, which facilitates cooperation in a social dilemma situation. Experimental results show that the...

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...
