This paper investigates the optimal rate of environmental tax and level of privatization in a vertical relationship between one partially privatized producer and two private sellers. The main results are as follows: First, privatization of the producer firm decreases environmental damage. Second, the optimal environmental tax rate equals the Pigouvian level. Third, fully nationalizing the producer firm is optimal when the government simultaneously decides upon the environmental tax rate
then, privatization decreases social welfare. © 2010 Springer Science+Business Media, LLC.

This paper studies a dynamic game of environmental taxes between two countries in the absence of explicit trade policies when both governments and firms act strategically. We demonstrate that the environmental tax in the steady-state equilibrium in a dynamic environmental tax game is lower than that in a static environmental one. Therefore, the dynamic behaviour of the governments results in an increase in the environmental damage. Further, as a result of international cooperation on environmental taxes between two countries in the beginning of policy competition, there is an increase in the optimal environmental tax. This implies that it is important to set cooperative environmental taxes in the beginning of policy competition because non-cooperative environmental taxes in the dynamic game result in the race-to-the-bottom, which does not lead to environmental improvement.

To analyze the motivations of Japanese companies to take environmental actions to reduce their greenhouse gas (GHG) emissions, we used FY2006 research data and questioned Japanese industries regarding their reduction of GHG emissions. Empirical investigations revealed that voluntary targets set by industry organizations, government requirements, and advance responses to possible future regulations can positively influence environmental actions for GHG emission reduction; however, cost reductions and corporate social responsibility fulfillment cannot.

This paper explores the optimal environmental tax and level of privatization in an international duopolistic market. We show that when the government is able to control the environmental tax and the extent of privatization, the optimal environmental tax is lower than the standard Pigouvian level. We also show that the optimal level of privatization of state-owned enterprises is partial privatization. Further, the optimal level of privatization is inversely dependent on the cleanup cost of past environmental contamination.

The analysis presented in this paper explores the interaction among privatization, environmental, and trade policies. In particular, we consider the optimal environmental tax and tariff, and the effects of privatization of a public firm in international duopolistic markets with environmental damage. There are three main results. First, the optimal environmental tax is lower than the marginal environmental damage and the optimal tariff is strictly positive regardless of whether or not the home public firm is privatized. Second, privatization leads to the increase in the optimal environmental taxes and tariffs in both countries. Third, under the optimal environmental tax and tariff, privatization results in the reduction of social welfare and in environmental improvement.<br>
