In aggregation theory, the admissibility condition for clustering together components to be aggregated is blockwise weak separability, which also is the condition needed to separate out sectors of the economy. Although weak separability is thereby of central importance in aggregation and index...

The treatment of owner-occupied housing costs is a recurring problem in the construction of consumer price indices, and there are competing methodologies. In the most widely-used Irish index, the Payments Approach, which attaches a weight to a term involving historical house prices and an...

The aggregation problem in demand analysis and exchange equilibrium is studied by putting restrictions on the shape of the distribution of the agents' characteristics. This is done by exploiting the finite dimensional linear structure induced on demand functions by affine transformations of the...

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...

Errors introduced by using aggregate data in estimating a consumer demand model have long been a concern. We study the effects of such errors on elasticity estimates derived from AIDS and QUAIDS models. Based on a survey of published articles, a generic parameterization of the income...

Pashardes (1991) and Banks, Blundell and Preston (1994) use parametric methods to estimate lifetime equivalence scales. Their approaches put parametric restrictions on the differences in within-period expenditure needs across household types, the intertemporal allocation of expenditure, and the...

This study provides strong empirical support for modeling the demand for monetary assets within a consumer demand framework. We estimate a linearised locally flexible almost ideal demand system, containing five monetary assets, over the period 1991Q4 to 1998Q4. Estimating the system in...

Using non-parametric weak separability tests that are extended to allow for measurement errors in the data, a broad group of UK monetary assets is found to be weakly separable from consumer goods and leisure over the larger part of the nineties. Financial innovations have made assets with...

The paper uses hedonic regression techniques in order to decompose the price of a house into land and structure components using readily available real estate sales data for a Dutch city. In order to get sensible results, it proved necessary to use a nonlinear regression model using data that...

This paper develops a new framework for measuring prices and quantities of commercial properties. In particular, it addresses problems associated with obtaining separate estimates for the land and structure components of a property. A key contribution is to address the problem of estimating...
