Prof Roger Hartley - research

Research interests

Specific research interests:

Roger's recent research is principally within economic theory, focussing on game theory and individual decision-making under risk.  Within game theory, he is interested in the theory and application of aggregative games and extensions of this work to games with multiple aggregates.  He also works on modelling decision-making under risk in collaboration with empirical researchers.

Current and recent research projects:

Roger has a long-running and ongoing project with Richard Cornes of the Australian National University on the study and application of aggregative games.  Areas of application include public and industrial economics and this work has resulted in a number of publications in public economics.  An extension of this research to games with multiple aggregates (with Alex Dickson of Strathclyde University) is leading to a novel and powerful approach to bilateral oligopoly (an underpinning to partial equilibrium in which price-taking is not imposed a priori).  A similar approach is being successfully applied to local public goods.

Following on from a highly successful ESRC-funded project with Gauthier Lanot (Umea University, Sweden) and Ian Walker (University of Lancaster) on the economics of the national lottery, Roger has recently completed work (also ESRC-funded) using data from the gameshow "Who wants to be a millionaire?" to study risk aversion with large payoffs.  A paper describing this work ("Who Really Wants to be a Millionaire?  Estimates of Risk Aversion from Gameshow Data.") is forthcoming in the Journal of Applied Econometrics.
