Reforms of Environmental Policies in the Presence of Cross‐border Pollution and Public–Private Clean‐up*
构建了一个两国模型，分析跨境污染下私人生产者和公共部门共同参与污染治理时的最优政策工具（排放税和公共治理资金），并考察多边政策改革的效果。
Abstract We construct a two‐country model where pollution from production is transmitted across borders. Pollution abatement is undertaken by both private producers and the public sector. We characterize Nash optimal levels of the policy instruments in the two countries: emission taxes and funds allocated for public abatement activities. We examine the implications of a number of multilateral policy reforms. One of our findings is that the magnitude of the beneficial effect of a reform depends on the scope of the reform; if it is restricted to a subset of policy instruments, then the efficacy of environmental policy reform can be greatly undermined.
