I'm a lecturer of Economics at the University of St Andrews. As an economic theorist, I'm interested in developing analytical tools and models to study a wide range of social and economic phenomena. My recent research interests can be summarised in two subtitles. Decision theory, in particular choice theory, is my first focus of interest. I aim to understand how individuals make their decisions. Mainstream economic theory assumes that individuals are rational; they are self-interested, fully informed about their own preferences and able to compare all possible options in a consistent way when making a decision. However both common sense and scientific evidence confirm that this indeed is not the case. There are many other factors that shape individual decision-making that cannot be simply explained by individual rationality. I aim to investigate those different mechanisms that are used by ‘boundedly rational’ individuals for decision-making. In particular, I am interested in the role of social influence/peer influence on individual behaviour. How do individuals influence each other’s behaviours? What are the mechanisms that we employ to influence each other? Can we disentangle the underlying influence only by looking at people’s behaviours? A second area of interest for me is inequality theory. In particular, I am interested in the design of inequality measures. It is crucial to design ‘proper inequality indices’ in order to evaluate inequalities correctly. One way to achieve this is axiomatisation; starting from the properties that would be required from an inequality index and deriving the measure that satisfies those. I am specifically interested in developing measures for the evaluation of non-income inequalities such as education, health and subjective well-being.
