1991 Nobel Laureate Ronald Coase will organize an international conference on China's Economic Transformation this July. Steven N. S. Cheung is also invited to give a keynote speech there, talking about his most recent paper, titled, "The Economic System of China".
Although this paper has not been put onto the conference website, here is some clue. As Cheung argued for himself, "...section three of this paper generalizes the concept of contract, by far nobody in the field of institutional economics has reached that far...". Let's hope!
