We derive testable implications of instrument validity in just identified treatment effect models with endogeneity and consider several tests. The identifying assumptions of the local average treatment effect allow us to both point identify and bound the mean potential outcomes of the always...

We develop a novel framework to analyze the structural implications of the marriage market for household consumption patterns. We start by defining a revealed preference characterization of efficient household consumption when the marriage is stable. In particular, stability means that the...

A theory of a wealth maximizing, capital accumulating, price taking firm facing adjustment costs and operating in the presence of disembodied and price-induced technical progress is developed. The testable implications of the extended theory are derived under mild assumptions and are thus...

We consider the testable implications of the Cournot model of market competition. Our approach is nonparametric in the sense that we abstain from imposing any functional specification on market demand and firm cost functions. We derive necessary and sufficient conditions for (reduced form)...

We develop a novel framework to analyze the structural implications of the marriage market for house-hold consumption patterns. We start by de…ning a revealed preference characterization of e¢ cient householdconsumption when the marriage is stable. In particular, stability means that the...

An exhaustive comparative statics analysis of a model of a monopolistic firm facing price-cap regulation and a variety of commonly implemented command-and-control environmental regulations is carried out. The comparative statics are intrinsic to each of the models and thus form their basic,...

This paper proposes a revealed preference test of network formation models. Specifically, I consider network formation models where agents are (1) strategic, (2) externalities are confined to within an agent’s k-neighborhood, where k can be varied. I show that this model can be tested...

The functional form used to represent expenditures or consumption as a function of income and household size (Engel relationship) dramatically affects estimates of elasticities of these variables. This impact also holds true when the elasticities are computed at the mean of the sample used. When...
