NONLINEAR MODEL OF EVALUATING THE ECONOMIC POLICIES FOR GLOBAL WARMING ISSUE TAKING INTO ACCOUNT THE COMPETITIVENESS IN INTERNATIONAL MARKET

摘要

In this paper, we attempt to evaluate the economic policies such as carbon tax and emissions trading from the international competitiveness's point of view. For this purpose, we make a nonlinear model of evaluating carbon tax in consideration of competitiveness in international market. By using this model, we analyze one carbon tax scenario and two international emissions trading scenarios. As results of analysis, we have obtained two conclusions. First, introduction of carbon tax for Japan is possible so long as countermeasures of government of Japan against gap in efficiency of CO_2 emissions between sectors are devised. Secondly, nonparticipation in international emissions trading is invalid.
