Theory predicts that efficiency prevails on credence goods markets if customers are able to verify which quality they receive from an expert seller. In a series of experiments with endogenous prices we observe that verifiability fails to result in efficient provision behaviour and leads to very...

"We develop an evolutionary game theory model for a limited access common pool resource. With full disclosure of individual extraction decisions and payoffs we conjecture that subjects will imitate the most successful players’ strategy as long as their payoffs increase. We derive a stable...

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...

"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...

"In particular, the academic debate over the best prediction about the behavior of people that use a common-pool resource (CPR), and the recommended policy approaches to the CPR dilemma have undergone a very interesting evolution throughout the last 3 decades of the pastcentury, since the...

"In this paper we employ experimental economic methods to examine the effect of market structure on the use of marketable emissions permits. In particular, we ask whether firms can strategically manipulate a product market using marketable emissions permits. Subjects participate in two markets,...

"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...

"There has been extensive debate in the experimental economics literature as to the validity of extending the results of student experiments to more complex real world settings, characterised by the economic behaviour of diverse participants. This paper uses an experimental design that formally...

"In 1968, Hardin argued that all commonly-owned resources would tragically be depleted unless private ownership was granted. There are many case studies which prove Hardin wrong. Common-pool resources have been managed with success. However, this success does not imply (as some believe) that...
