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...

"Planning efforts in the SA Murray Darling Basin (SAMDB) have focused on the revegetation of degraded, privately held agricultural land, using locally native species, to meet prescribed resource condition targets of increased biodiversity, carbon sequestration, salinity and wind erosion...

"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...

"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...
