Analysis of consumer demand -

Research in this area involves modelling how households and individuals choose to allocate their expenditure across goods. Work includes modelling how sensitive choices are to changes in prices, incomes and advertising and how this varies across different types of people, as well as revealed preference analysis, which seeks to explore whether data on consumer choices are consistent with specific economic models.

The effects of banning advertising in junk food markets

There are growing calls to restrict advertising of junk foods. Whether such a move will improve diet quality will depend on how advertising shifts consumer demands and how firms respond. We study an important and typical junk food market – the potato chips market.
