I graduated in mathematics and social psychology at the University of Utrecht. After working as a researcher on social security at the Ministry of Social affairs and as a research associate in psychology at the University of Amsterdam (where I obtained my doctorate degree), I joined CREED in February 1992. I am mainly interested in (experimental) research in which insights from economics and other social sciences (e.g. psychology) are combined or contrasted: expectation formation, bargaining, social behavior, law & economics and individual search behavior (see the abstracts of working papers and publications below). In recent years I have become interested in behavioral finance and behavioral economics. Part of the research is done in the Center for Nonlinear Dynamics in Economics and Finance (CeNDEF). I am a member of the editorial board of Quantitative Finance and the Journal of Economic Psychology and I have been an Associate Editor of the European Economic Review from 2006-2012. I am also a Research Fellow of the Tinbergen Institute. Other (non-working related) interests are modern literature, modern art and vegetarian cooking.
