This paper proves core-equivalence theorems for exchange economies without ordered preferences, defined on locally convex Riesz commodity spaces such that the price space is a lattice. Properness assumptions are borrowed from some recent equilibrium existence results

Social demand functions result from the budget constrained maximization of "social preferences" or "other regarding preferences." These preferences are non-selfish in the sense that they also depend on other consumers' wealth. This paper addresses the robustness to wealth externalities of the...

This chapter reviews the theory of the voluntary public and private redistribution of wealth elaborated by economic analysis in the last forty years or so. The central object of the theory is altruistic gift-giving, construed as benevolent voluntary redistribution of income or wealth. The theory...

In contrast to the neo-classical theory of Arrow and Debreu, a model of a private ownership economy ispresented, in which production and consumption bundles are treated separately. Each ofthe two types of bundles is assumed to establish a convex cone. Production technologies can convert...

Bei unvollkommenen Märkten und numerairen Vermögen gibt es eine offene Menge an Volkswirtschaften, so dass die Gleichgewichtsverteilung durch eine veränderte Anfangsverteilung verbessert werden kann. Dies stärkt das klassische Ergebnis der eingeschränkten Pareto Ineffizienz von...

This paper examines a dynamic general equilibrium model with supply friction. With or without friction, the competitive equilibrium is efficient. Without friction, the market price is completely determined by the marginal production cost. If friction is present, no matter how small, then the...

Economists commonly use the Edgeworth box to illustrate the ability of exchange to generate gains from trade. In contrast to this framework of dyadic exchange, we explore triadic forms of exchange where margins of coercion are also present. In the presence of triadic exchange, market...

The effect of the presence of an externality in a general equilibrium scenario is illustrated in a standard Edgeworth box. Assuming utility functions parameterized by the incidence of the externality and taking into account the resource constraints when deriving agents' indifference curves for...
