OLG模型分析了在自由放任经济和通过政府控制的许可证市场监管的经济中，累积污染物的排放量。政府要么接受许可证市场上的价格，要么以古诺价格出售所需的许可证。第一种管制被称为“自由环境政策”，第二种管制被称为“垄断环境政策”。研究了该机制的前瞻暂态平衡点和定态平衡点以及污染边界。如果人们可以在自由放任和监管之间(或者在自由和垄断的环境政策体制之间)做出选择，那么一般来说，就不存在稳定状态。相反，内生政策周期可以在自由放任和监管之间交替，也可以在自由监管和垄断监管之间交替。
The OLG-model analyzes emissions of an accumulative pollutant in a laissez-faire economy and an economy regulated through a government controlled license market. The government either takes the price on the license market as given or sells the licenses demanded at the Cournot price. The first type of regulation is called a 'liberal environmental policy', and the second type a 'monopolistic environmental policy'. The forward looking temporary and the stationary equilibria as well as the pollution boundaries of the mechanisms are studied. If people can choose between laissez-faire and regulation (or between the liberal and the monopolistic environmental policy regime), then in general no steady state exists. Instead endogenous policy cycles can alternate between laissez-faire and regulation or between liberal and monopolistic regulation.
