The model has two stages. In the first stage, the government sets the environmental tax. Then, the firms engage in a Cournot competition, choosing output and pollution abatement levels. We also compare the results obtained with the ones got when the public firm aims to maximize the sum of consumer surplus and the firm’s profit.engIndustrial organizationGame TheoryCournot modelEnvironmentPrivatizationjournal article10.18576/amis/100503
