We study observational learning in environments with congestion costs: as more of one's predecessors choose an action, the payoff from choosing that action decreases. If congestion on either action can get so large that an agent would prefer to take the other action no matter his beliefs about...

There is evidence that people do not fully take into account how other people’s actions are contingent on these others’ information. This paper defines and applies a new equilibrium concept in games with private information, "cursed equilibrium", which assumes that each player correctly...

We investigate experimentally whether social learners appreciate the redundancy of information conveyed by their observed predecessors\' actions. Each participant observes a private signal and enters an estimate of the sum of all earlier-moving participants\' signals plus her own. In a first...

We model a financial market where some traders of a risky asset do not fully appreciate what prices convey about others' private information. Markets comprising solely such "cursed" traders generate more trade than those comprising solely rationals. Because rationals arbitrage distortions caused...

We present a model of a financial market where some traders are "cursed" when choosing how much to invest in a risky asset, failing to fully take into account what prices convey about others' private information. Cursed traders put more weight on their private signals than rational traders. But...
