How do we decide about our health? For Stefan Lipman, this question is core to his research, teaching and train of thought. He is mainly interested in finding answers to this question by combining insights from health economics, behavioral economics, and psychology. Stefan studied social and health psychology, and currently is a Ph.D. candidate at Erasmus University Rotterdam. Most of his work has focused on risk and time preference for health, valuation of health and quality of life and understanding healthy behaviour.
