Environmental Economics


Toru MOROTOMI, Professor


The purpose of this laboratory is to analyze climate change policies and energy policies from economics perspectives. In order to do so, we request all the applicants for this laboratory to study environmental economics as its theoretical foundation. Based on this, we focus on the following three research topics:

Topics of Research

【1】 Economic analysis of climate change policies and their policy designs

We focus mainly on climate change policies among various environmental issues. As a role of social science, design of social institutions and policy instruments is one of the most important tasks. Environmental policy instruments (environmental taxes, emissions trading systems, subsidies, etc.) are main target of our research.

【2】Renewable energies and electricity market liberalization

Renewable energy policies play a crucial role in the climate change policies. On the other hand, research of the future power systems that make the large-scale renewable energy generation and grid integration possible is also important. This laboratory promotes a research project that supports transition of power systems from the centralized one to more distributed one, by increasing renewable energies in the liberalized electricity market environment.

【3】Renewable energies and regional rehabilitation

Unlike the fossil fuels and nuclear energies, renewables are the universally distributed energy resources for any regions. We are tackling the issue of how to link renewable energy development with the regional rehabilitation. Collaborating with municipalities, we are currently engaged in “reginal added value analysis” and research on appropriate forms of business entities like “Stadtweke” or energy cooperatives.
