Research Field
Industrial Organization, Competition Policy
Research Theme
My main research interests have been in the areas of industrial organization, international trade, and transportation. I often use a structural estimation method to analyze the effectiveness of government policies and the role of business strategies.

1. I have estimated the presence of increasing returns to scale in various economic contexts. My work includes (a) a study of the U.S. VCR market in the 1970s and 80s -- the role of network externalities in the format competition between VHS and Beta; (b) a study of the Japanese steel industry in 1955-65 -- the effectiveness of export subsidies; and (c) a study of the international air cargo business in the Northeast Asian region -- the importance of handling time and airport charges in order for an airport to become a hub in the area.

2. I have analyzed the anticipatory effects of trade policies. It is known that the anticipation of such a policy introduction distorts an incentive of economic agents before the policy is actually implemented. I have identified the evidence through estimating a competition model.
