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.
