I have two main areas of research, insurance and historical markets, and I also do research on pedagogy.

My insurance research analyses the effect of a lack of information. Much of my work follows a mainstream concern within economics that customers may know more about their personal characteristics then insurance providers (called "adverse selection") and I am currently analysing this for motor insurance and life annuities (annuities are a form of pension which insures against pensioners running out of money in retirement). Another problem which has been of less interest to economists is that customers may not fully understand what they are purchasing and I have analysed this in the motor insurance industry.

My second area of research is the efficiency of historical markets (i.e. does supply and demand work?). Current research uses archival sources and econometric methods to evaluate whether existing studies of prices are reliable indicators of market efficiency when there is unobserved quality variation and grain storage.

In the area of pedagogy I have recently finished research on Student Evaluations of Teaching. While it is important to understand students' experiences of how they are taught, such evaluations may fail to describe teaching quality sufficiently well for some of the purposes for which SETs are used.
