We consider a "yardstick competition" scheme based on the difference between a firm's marginal externality and the average marginal externality of the industry. In this paper, we investigate the condition that this scheme is more efficient than pigouvian tax. We show that the yardstick scheme is more efficient than pigouvian tax unless the marginal externality and the cost of pollution abatement investment are high.}, pages = {1--7}, title = {環境税のヤードスティック税制に関する考察}, volume = {25}, year = {2017} }
