Recent experiments show that public goods can be provided at high levels when mutual monitoring and costly punishment are allowed. All these experiments, however, study monitoring and punishment in a setting where all agents can monitor and punish each other (i.e., in a complete network). The...

Social learning is the process of individuals learning by observing the actions of others. One odd aspect of the literature on social learning though is that, ironically, learning is not very social because in the real world, although people learn by observing the actions of others, they also...

The Allais critique of expected utility theory (EUT) has led to the development of theories of choice under risk that relax the independence axiom, but which adhere to the conventional axioms of ordering and monotonicity. Unlike many existing labora-tory experiments designed to test...

We report a portfolio-choice experiment that enables us to estimate parametric models of ambiguity aversion at the level of the individual subject. The assets are Arrow securities that correspond to three states of nature, where one state is risky with known probability and two states are...

Individuals living in society are bound together by a social network, the complex of relationships that brings them into contact with other agents. In many social and economic situations, individuals learn by observing the behavior of others in their local environment. This process is called...

We report an experimental test of the four touchstones of rationality in choice under risk – utility maximization, stochastic dominance, expected-utility maximization and small-stakes risk neutrality – with students from one of the best universities in the United States and one of the best...

We report a laboratory experiment that enables us to distinguish preferences for altruism (concerning tradeoffs between own payoffs and the payoffs of others) from social preferences (concerning tradeoffs between the payoffs of others). By using graphical representations of three-person Dictator...
