Previous studies of charitable giving have focused on middle- or high-income earners in Western countries, neglecting the poor, although the lowest income groups are often shown to contribute substantial shares of their income to charitable causes. In a large-scale natural field experiment with...

We analyze how the team formation process influences the ability composition and performance of teams, showing how self-selection and random assignment affect team performance for different tasks in two natural field experiments. We identify the collaboration intensity of the task as the key...
