Outline of Final Research Achievements

Over the last few decades, environmental policies have taken a variety of forms and designs. This study investigated how alternative designs of environmental policies influence the size distribution and mass of firms within and across industries in the long run, in a general equilibrium model that accounts for endogenous entry and exit of heterogeneous firms. The welfare impacts of environmental policies were analytically decomposed into the effects on economy-wide income, mass of firms, size distribution, price markups, and factor prices. We also extended the study to a multi-country setup in order to incorporate international trade of commodities. Furthermore, we quantified the impacts of Japan’s green vehicle taxation policy since 2009, estimating a random-coefficients logit model with quarterly automobile sales data between 2007 and 2012 from the Japanese new car market.
