The value of information and the possibility of speculation are examined in an environment with unawareness. Although agents have “correct†prior beliefs about events they are aware of and have a clear understanding of their available actions and payoffs, their unawareness may lead...

For testing lack of correlation against spatial autoregressive alternatives, Lagrange multiplier tests enjoy their usual computational advantages, but the (X2) first-order asymptotic approximation to critical values can be poor in small samples. We develop refined tests for lack of spatial error...

Does a competitive equilibrium in a matching market provide adequate incentives for investments made before the market when utility is not perfectly transferable? This paper derives a necessary and sufficient condition for equilibrium investments to maximize surplus conditional on the matching...

A committee is choosing from two alternatives. If required supermajority is not reached, voting is repeated indefinitely, although there is a cost of delay. Under suitable assumptions the equilibrium analysis provides a sharp prediction. The result can be interpreted as a generalization of the...

Errors are common in strategic situations. We use a genetic algorithm to simulate the evolution of error-prone finite automata in the repeated Prisoner's Dilemma game. In particular, the automata are subjected to implementation and perception errors. The computational experiments assess whether...

Linear altruism is a functional form used extensively in outcome-based models of social preferences: the underlying assumption is that individuals have a utility over monetary outcome profiles that depends on their and other players' payments. Behavior in strategic interactions is explained as a...

A committee is choosing from two alternatives. If required supermajority is not reached, voting is repeated indefinitely, although there is a cost of delay. Under suitable assumptions the equilibrium analysis provides a sharp prediction. The result can be interpreted as a generalization of the...

This paper studies rigidities in sharing joint payoffs (non-transferability) as a source of excessive segregation in labor or education markets. The resulting distortions in ex-ante investments, such as education acquisition, link such mismatches to the possibility of simultaneous...

Do elementary statistics or equilibrium theory deliver any rules of thumb regarding how we should argue in debates? We suggest a framework for normative analysis of debates. In our framework, each discussant wants the audience to believe that the actual state coincides with the discussant's...
