Before and during the 2010 Soccer World Cup, participants made probabilistic forecasts for the outcomes of the tournament. We examine the relationship between their depression levels and their performance in this forecasting task. Across two different waves of predictions and with multiple...

We conduct experiments with 720 children ages 9-11 to evaluate the relationship of time and risk preferences with health. Children who are more patient report consuming fewer unhealthy calories and spending less time on sedentary activities such as video games. Children who are more risk seeking...

Under optimal tournament design, we would expect agents to exert identical effort regardless of the shape of the contest function’s error component. We report data from laboratory experiments that provide a first test of this prediction. We find that efforts do not significantly differ when...

We introduce a model of strategic experimentation on social networks where forwardlooking agents learn from their own and neighbors’ successes. In equilibrium, private discovery is followed by social diffusion. Social learning crowds out own experimentation, so total information decreases with...
