Valerie is an applied microeconomist, interested in understanding the behaviour of individuals, both theoretically and empirically, with the aim of informing policy. Part of her research focuses on modelling intra-household behaviour in order to understand how individuals interact to reach the decisions whose consequences we see. She is particularly interested in applying these models in the context of developing economies. She also has a long-standing interest in consumption and demand, which has informed both her research and policy oriented work, conducted for UK government bodies. She also works on health.
