Best nonparametric bounds on demand responses (2005)

There are three key dimensions by which revealed preference bounds on consumer demand responses can be improved. The first relates to the improvements that arise from using expansion paths for given...

Best nonparametric bounds on demand responses (2005)

This paper uses revealed preference inequalities to provide the tightest possible (best) nonparametric bounds on consumer responses to price changes using consumer level data over a finite set of...

Nonparametric methods for the characteristic model (2004)

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...

Blow, L., Browning, M., Crawford, I.

Characteristics models have been found to be useful in many areas of economics. However, their empirical implementation tends to rely heavily on functional form assumptions. In this paper we develop...

Valuing a new good (2004)

An analysis of the Hastings review: "The effects of food promotion on children" (2003)

This paper presents a nonparametric method for calculating a lower bound on the virtual or reservation price of a new good. This allows the welfare effects of product market innovations to be...

Estimation of household demand systems with theoretically compatible Engel curves and unit value specifications (2003)

Crawford, I., Laisney, F., Preston, I.

We develop a method for estimation of price reactions using unit value data which exploits the implicit links between quantity and unit value choices. This allows us to combine appealing Engel curve...

Testing the RPI data for consistency with the theory of the cost-of-living index (2002)

Crawford, I., Image, I.

This paper tests the published section level price and weight data used in the compilation of the UK Retail Prices Index for consistency with the theory of the cost-of-living index. We use a...

Cost-of-living indices and revealed preference (1999)

This report considers sources of bias in cost-of-living and price indices, with particular reference to the UK's retail price index. The sources of bias discussed are caused by the introduction of...

Valuing quality (1999)

A non-parametric bound on substitution bias in the UK retail prices index (1999)

This paper uses revealed preference restrictions and nonparametric statistical methods to bound a quality-constant price series for a good that changes quality over time. Unlike the more usual...

A quality-constant price index for new cars in the UK, 1986 to 1995 (1998)

This paper uses revealed preference restrictions and nonparametric statistical methods to bound true cost-of-living indices. These are compared to the popular price indices including the type used to...

The distributional effects of taxes on private motoring (1997)

This paper presents an hedonic model of the price of a sample of new cars available in the UK during the period 1986 to 1995. It overcomes the problem of collinearity in the characteristics data by...

Non-parametric Engel curves and revealed preferences (1997)

In this Commentary, the authors look at the likely effects that real year-by-year increases in road fuel duties will have on the use of cars by households and on their economic welfare, with...

A revealed preference method for valuing new goods (1996)

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...

Estimation of household demand systems using unit value data (1996)

This paper presents a revealed preference method for calculating a lower bound on the virtual price of new goods and suggests a way to improve these bounds by using non-parametric expansion paths....

Preston, I., Crawford, I., Laisney, F.

Many budget surveys present the interesting feature that for a wide range of goods they contain information, not only on expenditures, but also on quantities consumed. This allows the computation of...

Distributional aspects of the introduction of VAT on domestic energy (1993)

Crawford, I., Smith, S., Webb, S.

This paper considers the impact on households of imposing VAT on domestic energy, and the extent to which the social security system will safeguard poorer households against the additional tax burden.
