When individuals trade with strangers, there is a temptation to renege on contracts. In the absence of repeated interaction or exogenous enforcement mechanisms, this problem can impede valuable exchange. Historically, individuals have solved this problem by forming institutions that sustain...

Donations and volunteerism can be conceived as market transactions with zero explicit price. However, evidence suggests people may not view zero as just another price when it comes to pro-­social behavior. Thus, while markets might be expected to increase the supply of assets available to those...
