Consumer behaviour

This paper develops a new approach to the estimation of consumer demand models with unobserved heterogeneity subject to revealed preference inequality restrictions.

Food purchases differ substantially across countries. We use detailed household level data from the US, France and the UK to (i) document these differences; (ii) estimate a demand system for food and nutrients, and (iii) simulate counterfactual choices if households faced prices and nutritional characteristics from other countries.

We evaluate the impact of a policing experiment that depenalized the possession of small quantities of cannabis in the London borough of Lambeth, on hospital admissions related to illicit drug use.

estimate and test the restrictions of a collective model of household consumption, using z-conditional demands, in the context of a large conditional cash transfer program in rural Mexico. The model can explain the impacts of the program on the structure of food consumption.

This paper considers whether households cut back on food spending to finance the additional cost of keeping warm during spells of unseasonably cold weather.

This report compares and contrasts the economic circumstances of individuals born between the 1940s and the 1970s, currently aged between their mid-30s and mid-70s.

There has been a marked increase in body weight across much of the developed world. This has taken place, even though data suggest that there has not been an increase in calories consumed. This leads to a puzzle. If calories are declining, why are people gaining weight?

In this briefing note, we document how the food purchases of households in the UK have changed over the recent period of recession and food price rises.

In this paper, we estimate a collective model of household consumption and test the restrictions of collective rationality using z-conditional demands in the context of a large Conditional Cash Transfer programme in rural Mexico.
