Most of my research is concerned with choice under uncertainty and its applications in
economics and finance. In particular I have been concerned with ambiguity (decisions where some or
all of the relevant probabilities are unknown). A major area of research has been the impact of ambiguity
in games. Applications include partnerships, asset pricing and the law of liability. Currently I am
working on experimental tests of these theories.
I have recently been working on a Leverhulme funded project on decision-making
within firms. Topics studied will include how corporate governance influences behaviour in the product
market. I am particularly interested in the factors which influence the way firms are organised e.g. the
choice between for-profit firms, cooperatives and partnerships. This will be relevant for issues such as
mergers and corporate governance.
