Recent Research Interests

My research fields are International Economics and Industrial Organization (i.e., Applied Microeconomics). My current research interests are network externality and product compatibility (i.e., interoperability and interconnectivity) in network industries. I study the effect of trade and industrial policies on the network industries, based on international oligopoly models.
