The study of collective action requires an understanding of the individual incentives and of the institutional constraints that guide people in making choices about cooperating or defecting on the group facing the dilemma. The use of local ecosystems by groups of individuals is just one example...

Many forest ecosystems provide multiple goods and services to both local users (e.g. firewood, water) and to other external beneficiaries (biodiversity conservation, carbon sequestration). This calls for alternative approaches in the governance of these local ecosystems. Even if local users...

A large, but inconclusive, literature addresses how economic heterogeneity affects the use of local resources and local environmental quality. One line of thought, which derives from Nash equilibrium provision of public goods, suggests that in contexts in which individual actions degrade local...

This paper explores how wealth and inequality can affect self-governed solutions to commons dilemmas by constraining group cooperation. It reports a series of experiments in the field where subjects are actual commons users. Household data about the participants-context explain statistically the...

Regulations that are designed to improve social welfare typically begin with the premise that individuals are purely self-interested. Experimental evidence shows, however, that individuals do not typically behave this way; instead, they tend to strike a balance between self and group interests....

The use of experimental settings to observe human behaviour in a controlled environment of incentives, rules and institutions, has been widely used by the behavioural sciences for some time now, particularly by psychology and economics. In most cases the subjects are college students recruited...

An experimental approach is used to examine the performance of three different multi-unit auction designs: discriminatory, uniform-price with fixed supply, and uniform-price with endogenous supply. We find that the strategies of the individual bidders and the aggregate demand curves are...

Does individual behavior in a laboratory setting provide a reliable indicator of behavior in a naturally occurring setting? We consider this general methodological question in the context of eliciting risk attitudes. The controls that are typically employed in laboratory settings, such as the...
