On June 3, 2018, we invited Prof. Heiwai Tang, Associate Professor of International Economics at the Johns Hopkins School of Advanced International Studies, who gave a talk entitled “Causes and Implications of the US-China Trade War”, based on his recent empirical research about firms’ stock market reactions to the recent announcements by both countries and his ongoing work on global value chains. He analyzed the economic cost of the announcement of “Trade War” and used the data source from US firms’ exposure to trade, to Chinese companies exposure to trade. It is certainly a very interesting talk and attracts a lot of audience.
