Grassroots fundraising leverages favor trading in social networks to support the provision of a public good. We use a laboratory experiment to study the elements and dynamics of this type of institution. Peer-to-peer reciprocity is important, and having the ability to practice targeted...

We use lab experiments to study policies that address common pool resource overuse. We look at a price mechanism, specifically a Pigouvian subsidy, and four non-price interventions. The non-price policies are information alone, information with a normative message, communication alone, and...

Temporal spillovers occur when a conservation program changes what happens to land outside the temporal window of the conservation contract. This may happen when conservation improves land so that returns to non-conservation uses are increased, or when landowners' preferences become more...

Temporal spillovers occur when a conservation program changes the use made of a land parcel outside of the window of the conservation contract. This may happen when conservation improves land so that returns to non-conservation uses are increased, or when landowners' preferences become more...

Favor trading is common. We do something nice for someone and they do something nice in return. Several motives might underlie such behavior, including altruism, strategic motives, and direct or indirect positive reciprocity. It is not yet well-understood how these fit together to affect...

Some policy problems pit one group׳s interests against another׳s. One group may determine provision of a project (such as a dam) that benefits group members but hurts others. We introduce a model of such projects. In-group members may contribute to a common fund that benefits them as a public...

We develop an axiomatic theory that integrates the discovered preference hypothesis into neoclassical microeconomic choice theory. A theory in which preferences must be discovered through experience can explain patterns observed in choice data, including preference reversals, evolution of or...

Lottery experiments have been performed in many contexts to test theories of risk aversion and to measure risk preferences. People are typically offered a series of lotteries with increasing expected payoffs and variances. A person with a concave utility function should switch from risky bets to...
