Research topics are in the areas of environmental economics and political economy of environmental policy. My special interests and specialized fields are theoretical and empirical analysis on climate change, energy and sustainable development. I have been conducted on analysis of the economic impact of environmental policy and international cooperation. I am currently working on the decision-making process in the environmental issues of economic agents and the effective policy measures for each environmental issue. I am also interested in the theory and application of voluntary environmental actions taken by individual, private corporations and the informal sector and the links between ecotourism and environmental education, international trade and the environment.
