No 206, Discussion Paper Series from School of Economics, Kwansei Gakuin University

Abstract: This study theoretically examines green portfolio standards with monetary penalties in an oligopoly market. We find that green portfolio standards are inefficient policy tools if the purpose of the government is to promote green products, whereas they attain firstbest optimality if the purpose is to restrict non-green products. Green portfolio standards may work well under the mixed aims of promoting green and restricting non-green products. Moreover, by applying the principle of our results, we highlight the inefficiency of an employment promotion program for handicapped workers in Japan.
