Recent Developments in Modelling Preferences under Risk

Ever since von Neumann and Morgenstern presented their expected utility theory, the axioms (assumptions) underlying their theory have been intensely debated and tested. Recently, a variety of theories have been presented which model preferences by weakening some of the assumptions of expected utility theory. We describe some of these theories, examine their properties, and provide insights into how they work. Implications for different areas of business research are discussed.
