We study a novel, repeated common pool resource game in which current resource stocks depend on resource extraction in previous periods. Our model shows that for a sufficiently high regrowth rate, there is no commons dilemma: the resource will be preserved indefinitely in equilibrium. Lower...

In a novel laboratory asset market, traders buy and sell shares of a monopolist while observing its price and transaction history in real-time. Dividends are based on the profitability of the monopolist, also an experimental subject. Despite dividend uncertainty resulting from both monopolist...

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...

We develop a unifying explanation for prosocial behavior. We argue that people care not about others’ payoffs per se, but whether their own behavior accords with social norms. Individuals who are sensitive to norms will adhere to them so long as they observe others doing the same. A model...

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...

The history of the world is strewn with the remains of societies whose institutions failed to adapt to ecological change, but the determinants of institutional fragility are difficult to identify in the historical record. We report a laboratory experiment that explores the impact of an exogenous...

Rules are thought to persist to the extent that the direct benefits of having them (e.g. reduced transactions costs) exceed the costs of enforcement and of occasional misapplications. We argue that a second crucial role of rules is as screening mechanisms for identifying cooperative types. Thus...

In laboratory asset markets, subjects trade shares of a firm whose profits in a linked product market determine dividends. Treatments vary whether dividend information is revealed once per period or in real-time and whether the firm is controlled by a profit-maximizing robot or human subject....
