Financial Structure and the Effectiveness of Pollution Control in an Oligopolistic Industry

Abstract

This paper explores the link between pollution taxes and the financial and output decisions of firms in an oligopolistic industry facing demand uncertainty. It is shown that environmental regulations such as pollution taxes may induce firms to alter their financial structure, which in turn influences both output levels and the effectiveness of the tax in controlling pollution emissions. It is demonstrated that there exist circumstances in which highly leveraged firms may respond to pollution taxes by expanding output and emission levels. This possibility arises in a leveraged oligopoly since the tax acts as a credible commitment device which leads to more aggressive competition in output markets.
