Consumption and demand
Research in this area aims to understand the behaviour of consumers - their choice of which goods and services to purchase, the sensitivity of their decisions to changes in prices, the interdependence of decisions made by firms and those made by consumers and the implications of all these factors for government policy and for the wider economy.

Past research at the IFS has made substantial contributions to the understanding of these topics. Ongoing areas of interest include household consumption and how it changes over the lifecycle; the modelling of demand; behavioural economics and rationality; the measurement of consumption and expenditure; consumer and firm behaviour in the food market; the construction of price indices and the distributional impact of inflation.

Analysing the detailed off-licence alcohol purchase data of more than 19,000 households, this observation argues that the policy would be a very significant intervention.
