In this article we study coherent risk measures in general economic models where the set of financial positions is an ordered Banach space E and the safe asset an order unit x0 of E. First we study some properties of risk measures. We show that the set of normalized (with respect to x0) price...

This paper discusses the testable implications of the Walrasian hypotheses: H1 - Observed market demand is the sum of consumer's demands derived from utility maximization subject to budget constraints. H2 - There exists an observable (locally) unique equilibrium price system such that the...

Why do rent, wage, and sharecropping contracts exist simultaneously? One possibility is that contract types distinguish between workers with different endowments of managerial ability. This article describes an empirical test of the link between managerial ability and contract choice.

This work introduces a rigorous set-theoretic foundation of bilateral matching mechanisms and studies their properties in a systematic manner. By providing a unified framework to study ilateral matching mechanisms, we formalize how different spatial/informational constraints can be implemented...

This paper introduces, within a general equilibrium setting, an alternate theory of value that provides a value-based characterization of the most important notions of allocative equilibria even in cases where the (Walrasian) uniform price-based characterizations need not be applicable. The...
