Jingang Zhao is Professor of Economics at the University of Saskatchewan. He previously taught at Ohio Sate University (1992-2000) and Iowa Sate University (2000-2002). He received his BE in Applied Math and Mechanics from Beijing Institute of Aeronautics and Astronautics in 1981, his MS in Optimization under Quanling Wei from Renmin University of China in 1984, and his PhD in Economics under Herbert Scarf, Martin Shubik and Richard Levin from Yale University in 1992. One of his major contributions is the discovery of hybrid games, which have been predicted as one of the three important areas in economic theory in the 21st century by JEP’s Forecasts for the Future of Economics (Allen 2000, p. 147). His other major discoveries include mathematical formulations for the Coase theorem and non-empty core as a precondition for horizontal mergers. One of his current research topics is free trade agreements in cooperative and hybrid games.
