Published as:"The Nature of Common-Pool Resource Problems," Rationality and Society 2(3), July 1990, 335-358."A large, multidisciplinary literature focuses on the problems occurring when multiple individuals concurrently use common-pool resources such as fisheries, grazing areas, airsheds, oil...

Subsequently published as:"Incorporating Motivational Heterogeneity into Game Theoretic Models of Collective Action." Public Choice, 117, 2003, 295-315."Understanding cooperation in the context of social dilemma games is fundamental to understanding how alternative institutional arrangements may...

"The experiments reported in this paper provide strong evidence for the power of face-to-face communication in a repeated common-pool resource environment where decisions are made privately. When communication was provided as a 'costless' institution, players successfully used the opportunity...

"Over the past 30 years, applied microeconomics has seen an explosion in the use of experimental methods as a tool for observing economic behavior. Economic experiments serve as a complement to field research using, allowing the researcher to create and control key theoretically based rules of...

This paper estimates and solves a multi-country version of the standard DSGE New Keynesian (NK) model. The country-specific models include a Phillips curve determining inflation, an IS curve determining output, a Taylor Rule determining interest rates, and a real effective exchange rate...

It is well-known in evolutionary game theory that population clustering in Prisoner's Dilemma games allows some cooperative strategies to invade populations of stable defecting strategies. We adapt this idea of population clustering to a two-person trust game. Without knowing it, players are...

"Laboratory experiments have generally supported the fundamental theorem that, in classical property rights environments, noncooperative behavior in large group markets yields efficient social outcomes. Experiments, however, regularly fail to support the game theoretic prediction of...

The Protestant Reformation is a vivid example of how religious transformation could set in motion institutional changes, leading to profound consequences for economic and political development. Although economists and other social scientists agree that there is a strong relation between the...

Cooperation between individuals requires the ability to infer each other’s mental states to form shared expectations over mutual gains and make cooperative choices that realize these gains. From evidence that the ability for mental state attribution involves the use of prefrontal cortex, we...

We design an experiment to examine behavior and welfare in a multi-level trust game representing a pass through investment in an intermediated market. In a repeated game, an investor invests via an intermediary who lends to a borrower. A pre-experiment one-shot version of the game serves as a...
