Countries that are forerunners in electricity market liberalization have encountered the problem of how to deal with market power of electricity suppliers. How to ensure competition in the electricity market is a crucial question facing Japan, which has started the liberalization process...

This paper focuses on anti-warming measures in the passenger vehicle sector and estimates the impacts of three policies in the green car taxation plan on consumer behavior with respect to car purchases. The three policies refer specifically to, first, preferential taxation for green vehicles;...

The most straightforward policy evaluation model is the consumer surplus approach, which adopts a partial equilibrium analysis framework. Using consumer surplus, which can be measured by the area to the left of the demand curve, this framework is extremely simple yet applicable in a surprising...
