This paper uses revealed preference inequalities to provide tight nonparametric bounds on consumer responses to price changes. Price responses are allowed to vary nonparametrically across the income distribution by exploiting microdata on consumer expenditures and incomes over a finite set of...

Varian (1988) showed that the utility maximization hypothesis cannot be falsified when only a subset of goods is observed. We show that this result does not hold under the assumptions that unobserved prices and expenditures remain constant. These assumptions are naturally satisfied in laboratory...

This paper introduces the Stata commands checkax, aei, and powers as a bundle within the package rpaxioms. The first command allows the user to test whether consumer demand data satisfy a number of revealed preference axioms at a given efficiency level, the second command calculates measures of...

Generalised Axiom of Revealed Preferences (GARP), that is, they are consistent with utility maximisation. The choices are drawn … from an approximate uniform distribution on the admissible region on each budget which ensures consistency with GARP, based … it can be used to approximate the power of tests for conditions for which GARP is a necessary but not sufficient …

This paper proposes new power indices for revealed preference tests. The indices are based on a model of irrational consumption behavior where the consumer randomly allocates a certain fraction of expenditure. The methods allow a researcher to trace out the entire power curve against random...

In this paper, we review the German practice of imputing the costs of owner-occupied housing by increasing the relative weight of actual rents in the CPI. As the structure of owner-occupied housing differs substantially from that of rental housing, this variant of the imputation method may cause...

Calculation of purchasing power parities based on observed consumer behaviour typically relies on the existence of some kind of 'international preferences'. We argue that this unrealistic assumption can be abandoned in 'regional' studies of purchasing power, where prices in both territories...

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...

In several studies, hedonic methods have been used successfully for the ex post assessment of the accuracy of inflation measurement. Most of those studies relate to high-tech products, with respect to which traditional methods of compiling price indices often fail. We apply hedonic methods to...
