Let X be a non-empty, compact, convex set in R and an upper semi-continuous mapping from X to the collection of non-empty, compact, convex subsets in R. Its is well knwon that such a mapping has a stationary point in X, i.e. there exists a point in X satisfying that its image under has a...

In this paper we present a new iterative auction, the bisection auction, that can be used for the sale of a single indivisable object. We will show that the bisection auction is computationally more efficient than the classical English auction while it still preserves all characteristics the...

The general equilibrium model with incomplete asset markets provides a unified framework for many problems in finance and macroeconomics. In its simplest version with only two time periods and a single physical commodity the model is ideally suited for the study of problems in cross sectional...

In general equilibrium models of financial markets, the cpital asset pricing formula does not hold when agents have von Neumann-Morgenstern utility with constant relative risk aversion. In this paper we examine under which conditions on endownments and dividens the pricing formula provides a...

There is a growing body of research in economics that studies the consequences of time-inconsistent preferences. This paper introduces time-inconsistent preferences in a general equilibrium setting. We discuss how the standard notion of competitive equilibrium should be extended in order to...

When the asset market is incomplete, competitive equilibria are constrained suboptimal, which provides scope for Pareto improving interventions. Price regulation can be such a Pareto improving policy, even when the welfare effects of rationing are taken into account. An appealing aspect of price...

Social environments constitute a framework in which it is possible to study how groups of agents interact in a society. The framework is general enough to analyse both non-cooperative and cooperative games. We identify a number of shortcomings of existing solution concepts that are used for...

We propose a new concept, the pairwise farsightedly stable set, in order to predict which networks may be formed among farsighted players. A set of networks G is pairwise farsightedly stable (i) if all possible pairwise deviations from any network g ∈ G to a network outside G are deterred by...

At arbitrary prices of commodities and assets, fix-price equilibria exist under weak assumptions: endowments need not satisfy an interiority condition, utility functions need only satisfy are very weak monotonicity requirement, and the asset return matrix allows for redundant assets. Prices of...

This article builds on the call of various authors (e.g. George & Jones, 2000; Mitchell & James,2001; Rousseau & Fried, 2001) for a better representation of time in theory-building andresearch in organizational behavior (OB). It proposes a radical temporalist approach to the study of OB which combines a...
