Professor Emeritus of Economics at the Ohio State University; Professor Emeritus (active) at Tel Aviv University. Expert on foundation of modern decision theory. He developed and participated in development of non-Bayesian decision making including non-additive probabilities, multiple priors and probabilistic sophistication, and of case-based decision models. These models made possible a distinction between risk (known probabilities) and uncertainty, and are consistent with evidence conflicting with the standard modes. He also introduced the nucleolus, a solution concept of cooperative games, and extended non-cooperative games to continuum of players. Beyond works in games and decisions His research covers topics in microeconomics theory, including general equilibrium, implementation and economic equity.
