In this paper we argue that ambiguity, combined with social opinion formation can be represented as part of a game-theoretic equilibrium concept that transcends the standard Nash equilibrium concept, applied to a model of the tragedy of the commons. Our modeling can shed some light on the...

We discuss the emerging field of New Classical economics from the perspective of some classical economic questions regarding the generation of wealth. We limit our discussion to the foundations of the emerging field and do not provide a complete overview of the details of the literature. We...

We present a general equilibrium model that encompasses the endogenous selection and shadow-pricing of a set of tradeable commodities, with home-based and social production activities. In the model, a "market system" is a set of costly social institutions which embody the trade and production...

We present a general equilibrium model that encompasses the endogenous selection of a set of tradeable commodities. At its foundation we introduce the notion of a trade infrastructure as a set of social institutions describing the trade and production technologies available to the agents in the...

We model an economy with social institutions that facilitate trade and induce three types of costs: establishment costs, access costs, and use costs. Use costs are specific transaction costs related to the use of these trade institutions. We assume that a trade institution is economically...

In the theory of economies with public goods one usually considers the case in which private goods are essential, i.e., each agent receives a fixed minimum level of utility if he consumes no private goods, irrespective of the public goods consumed. This paper develops the second welfare theorem...

In this paper we argue that ambiguity, combined with social opinion formation, can be used as the foundation of a game-theoretic equilibrium concept that transcends the standard Nash equilibrium concept, applied to a model of the tragedy of the commons. Our approach sheds light on the...
