In this paper I consider the following problem: there is a collection of, exogenously given, socially feasible sets, and for each one of them, each one of a group of individuals chooses from an individually feasible set. The fact that the product of the individually feasible sets is larger than...

It is shown that preferences can be constructed from observed choice behavior in a way that is robust to indifferent selection (i.e., the agent is indifferent between two alternatives but, nevertheless, is only observed selecting one of them). More precisely, a suggestion by Savage (1954) to...

This paper explores the empirical content of the weak axiom of revealed preference (WARP) for repeated cross-sectional data or for panel data where individuals experience preference shocks. Specifically, in a heterogeneous population, think of the fraction of consumers violating WARP as the...

An observer makes a number of observations of an industry producing a homogeneous good.  Each observation consists of the market price, the output of individual firms and perhaps information on each firm's production cost.  We provide various tests (typically, linear programs) with which the...

The elevation of scarcity to the fundamental economic problem rests on some unstated normative assumptions. These include a political commitment to private property, a methodological commitment to not inquire about taste formation, and the idea that human welfare is roughly equivalent to...

In order to treat a natural schedule matching problem related with worker-firm matchings, we generalize some theorems of Baiou--Balinski and Alkan--Gale by applying a fixed point method of Fleiner.

Economic analyses of nature must somehow define the “environmental commodities” to which values are attached. This paper articulates a set of principles to guide the choice and interpretation of nonmarket commodities. We describe how complex natural systems can be decomposed consistent with...

Evidence showing that individual behavior often deviates from the classical principle of preference maximization has raised at least two important questions: (i) How serious are the deviations? and (ii) What is the best way to analyse choice behavior in order to extract information for the...

An observer makes a number of observations of an industry producing a homoge- neous good. Each observation consists of the market price, the output of individual firms and perhaps information on each firm's production cost. We provide vari- ous tests (typically, linear programs) with which the...
