Previous research showed that ambient charges can decrease NPS pollution in a two-firm Cournot duopoly model. We extend this analysis to demonstrate that ambient charges can abate NPS pollution in an n-firm Cournot oligopoly case. We use standard market demand functions for n-firm Cournot cases in the same industry. The results show that a reduction in NPS pollution occurs not only in a static Cournot duopoly case, but also in a static n-firm Cournot oligopoly cases.}, pages = {251--258}, title = {The Effectiveness of Ambient Charges in a Static n-firm Cournot Oligopoly}, year = {2021} }
