| Outline of Final Research Achievements |
We consider optimal environmental policies under asymmetric information between polluters and the government. We also consider two types of private information. They are cost efficiency represented by parameters and the behavior of polluters itself like emission. Our study is composed of three works. In the two of them we consider type I private information. In the first project we developed a mechanism that can attain the first best, while in the second project we compared between tax and emission trading scheme in the long run. In the final project, we considered type II private information and derived a mechanism that can attain the first best.
