Experimental studies show that the Nash equilibrium and its refinements are poor predictors of behavior in non-cooperative strategic games. Cooperation models, such as ERC and inequality aversion, yield superior predictions compared to the standard game theory predictions. However, those models...

The outcome of many social and economic interactions, such as stock-market transactions, is strongly determined by the predictions that agents make about the behavior of other individuals. Cognitive hierarchy theory provides a framework to model the consequences of forecasting accuracy that has...

"Institutional approaches to social dilemmas have so far focused on how to create incentive structures that channel individuals' behavior into socially desirable outcomes assuming that everyone is selfish. However, the presumption of universal selfishness is not only empirically invalid but may...

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...

"In symmetric commons dilemmas, peer sanctioning, i.e. the possibility to gather information about the resource use of others and to sanction overuse, can be an effective structural solution in terms of resource conservation. However, most real world commons are characterized by structural...

"The dilemma structure underlying common-pool resource governance may prevail due to irreconcilable interests of actors, and may involve uncertainties resulting from the resource or actors involved. This paper addresses the knowledge and uncertainty problem in an analysis of electricity...

The outcome of many social and economic interactions, such as stock-market transactions, is strongly determined by the predictions that agents make about the behavior of other individuals. Cognitive hierarchy theory provides a framework to model the consequences of forecasting accuracy that has...

The paper presents an evolutionary model, based on the assumption that agents may revise their current strategies if they previously failed to attain the maximum level of potential payoffs. We offer three versions of this reflexive mechanism, each one of which describes a distinct type:...

Decision makers in dynamic environments such as air traffic control, firefighting, and call center operations adapt in real-time using outcome feedback. Understanding this adaptation is important for influencing and improving the decisions made. Recently, stimulus-response (S-R) learning models...
