This volume contains a collection of papers dealing with a broad range of topics in mathematical economics, game theory and economic dynamics. The contributions present both theoretical and applied research. The volume is dedicated to Mordecai Kurz. The papers were presented in a special...

This paper partially extends the f-core equivalence theorem of Hammond, Kaneko and Wooders (1989) for continuum economies with widespread externalities (i.e., those over which each individual has negligible control). Externalities need not result directly from trading activities. Neither free...

To allow conditioning on counterfactual events, zero probabilities can be replaced by infinitesimal probabilities that range over a non-Archimedean ordered field. This paper considers a suitable minimal field that is a complete metric space. Axioms similar to those in Anscombe and Aumann (1963)...

There are two distinct "Scandinavian consensus" approaches to public good supply, both based on agents' willingness to pay. A Wicksell-Foley public competitive equilibrium arises from a negative consensus in which no change of public environment, together with associated taxes and subsidies...

Arrow's "impossibility" and similar classical theorems are usually proved for an unrestricted domain of preference profiles. Recent work extends Arrow's theorem to various restricted but "saturating" domains of privately oriented, continuous, (strictly) convex, and (strictly) monotone "economic...
