Research keywords: Microeconomic and Game Theory, Economic Dynamics
Nick's fields of interest are microeconomic theory, game theory, industrial organization, evolutionary economics, and complex adaptive systems. His research focuses on the theory of markets and economic behaviour, and he is particularly interested in the dynamics of interactive processes involving bounded rational, learning agents. In relation to this, in his work he follows theoretical as well as experimental and computational tracks. He has investigated the meaning of the concept of rationality in economics, and analysed the link between, on the one hand, ideas of economies as complex adaptive systems (e.g. in recent Agent-based Computational Economics work), and on the other hand, much earlier views on self-organization in economics as advanced by Adam Smith or Hayek. He has worked on models of price dispersion and consumer loyalty and of the phenomenon of information-contagion, and he has investigated the relevance and implications of a range of learning theories both in theory and in experimental setups (including various oligopolistic markets, a location game, and ultimatum games). Recent work also includes the significance of focal points and of signalling in coordination games, and the measuring of the competitiveness of football leagues.
