This paper applies revealed preference theory to the nonparametric statistical analysis of consumer demand. Knowledge of expansion paths is shown to improve the power of nonparametric tests of revealed preference. The tightest bounds on indifference surfaces and welfare measures are derived...

The authors examine the effects of male and female labor supply on household demands and present a simple and robust test for the separability of demands from labor supply. Using data on individual households from six years of the U.K. Family Expenditure Survey, they estimate a demand system for...

This paper uses revealed preference inequalities to provide the tightest possible (best) nonparametric bounds on predicted consumer responses to price changes using consumer-level data over a finite set of relative price changes. These responses are allowed to vary nonparametrically across the...
