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...

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...
