We examine peer effects in risk taking with complete information and compare explanations for peer effects based on relative payoff concerns to explanations that allow peer choices to matter. We vary experimentally whether individuals can condition a simple lottery choice on the lottery choice,...

Can algorithms help people predict behavior in high-stakes prisoner’s dilemmas? Participants watching the pre-play communication of contestants in the TV show Golden Balls display a limited ability to predict contestants’ behavior, while algorithms do significantly better. We provide...
