摘要

我们建立了一个具有环境外部性的动态垄断模型，研究了对企业对污染积累的瞬时贡献征税的采用情况。后一个过程受到冲击，冲击是瞬时的。我们证明了一个最优税率的存在，使得垄断复制了与社会计划下相同的稳态福利水平。然而，相应的产出水平、环境友好技术研发投入和剩余分配必然与社会最优水平存在差异。

A Stochastic Optimal Control Model of Pollution Abatement

We model a dynamic monopoly with environmental externalities,investigating the adoption of a tax levied on the firm's instantaneous contribution to the accumulation of pollution. The latter process is subject to a shock, which is i.i.d. across instants. We prove the existence of an optimal tax rate such that the monopoly replicates the same steady state welfare level as under social planning. Yet, the corresponding output level, R&D investment for environmental friendly technologies and surplus distribution necessarily differ from the socially optimal ones.
