The size and style of referencing for a large sample of 60 years of publications of the Cowles Foundation are examined. The influence of computerization is considered. Self-referencing is noted and some observations are made on the costs and distribution of research papers.

Examples of repeated destructive behavior abound throughout the history of human societies. This paper examines the role of social memory -- a society's vicarious beliefs about the past -- in creating and perpetuating destructive conflicts. We examine whether such behavior is consistent with the...

The knowledge constraints and transactions costs imposed by geographical distance, network connections and time conspire to justify local behavior as a good approximation for global rationality. We consider a class of games to illustrate this relationship and raise some questions as to what...

We consider preference relations over information that are monotone: more information is preferred to less. We prove that, if a preference relation on information about an uncountable set of states of nature is monotone, then it is not representable by a utility function.

In the empirical and theoretical literature a consumer's utility function is often assumed to be quasilinear. In this paper we provide necessary and sufficient conditions for testing if the consumer acts as if she is maximizing a quasilinear utility function over her budget set. If the...

Changes in total surplus and deadweight loss are traditional measures of economic welfare. We propose necessary and sufficient conditions for rationalizing consumer demand data with a quasilinear utility function. Under these conditions, consumer surplus is a valid measure of consumer welfare....

Afriat's original method of proof is restored by using the minmax theorem.

We show that all the fundamental properties of competitive equilibrium in Marshall's cardinal theory of value, as presented in Note XXI of the mathematical appendix to his Principles of Economics (1890), derive from the Strong Law of Demand. That is, existence, uniqueness, optimality, and global...

Studies of inequality often ignore resource allocation within the household. In doing so they miss an important element of the distribution of welfare that can vary dramatically depending on overall environmental and economic factors. Thus, measures of inequality that ignore intra household...

In this paper we develop an approach to measuring inequality and poverty that recognizes the fact that individuals within households may have both different preferences and differential access to resources. We argue that a measure based on estimates of the sharing rule is inadequate as an...
