Corporate social responsibility (CSR) and the environment: Does CSR increase emissions?
构建了一个垄断市场下的企业社会责任模型，发现企业社会责任虽然总能提升社会福利，但在环境损害严重且减排成本效率低时，利润最大化的垄断企业有动机表现出社会责任行为，且企业社会责任可能反而增加排放。
This paper develops a corporate social responsibility (CSR) model under a time-consistent emission tax in a monopoly market. This paper also analyzes the effects of CSR behavior on economic welfare and the environment. The results show that (i) the promotion of CSR invariably enhances social welfare, (ii) when environmental damage is serious and the cost efficiency of emission reduction is low, then a pure profit-maximizing monopolist has some incentives for behaving as a socially responsible firm to enhance its own net profit, and (iii) in stark contrast to common belief, CSR can yield an emission-increasing effect. Consequently, this paper reveals that CSR is not always beneficial for the environment.
