中文摘要：

本文在考虑污染治理的内生经济增长模型中引入时间不一致偏好,得到市场均衡的最优消费、最优污染治理投入和经济增长率,研究时间不一致偏好和污染对消费、污染治理投入、经济增长和福利成本的影响.本文研究发现时间不一致偏好会降低消费和污染治理投入,提高经济增长率和降低福利成本.污染的负生产效应越大,污染治理投入越多,消费、经济增长率越低,而福利成本越高.污染负效用参数和个体感受程度的影响是不确定的.

英文摘要：

In this paper, we introduce inconsistent time preferences into a stochastic endogenous economic growth model with pollution abatement. The optimal consumption, the optimal pollution abatement spending and the optimal economic growth rate are obtained, the implications of inconsistent time preferences and pollution on consumption, pollution abatement spending, economic growth and welfare cost are studied. It is found that inconsistent time preferences lower consumption and pollution abatement spending increase the economic growth rate and decrease welfare cost. The more the negative production effect of pollution, the more the pollution abatement spending and the welfare cost, the much lower the consumption and the economic growth rate. The effects of the negative utility parameter and the individual＇s perception of pollution are uncertain.
