Most studies on the green tax reform issue point out that environmental taxes exacerbate pre-existing tax distortions, thereby increasing the welfare costs associated with the overall tax code. As a result, the optimal environmental tax should lie below the Pigovian level (or marginal social...

This paper builds a model of a region with two non-identical countries, cross-border pollution and free movements of goods and capital within the region. Pollution reduces welfare and there is simultaneous private and public pollution abatement. Public pollution abatement is financed with the...

The paper examines the interaction among taxes on factors income, environmental quality and welfare. We construct a two-country regional block model with capital mobility and cross-border pollution. Pollution in the two countries is simultaneously abated by the private sector, in response to a...

The use of environmental taxes for pollution problems without spillovers is studied in a multi-jurisdictional setting. The problem is studied using the standard Mintz & Tulkens (1986) model for interjurisdictional tax competition. This is a model with 2 regions, two tradeable private goods:...

We compare the effects of taxes and quotas for an environmental problem in which the regulator and polluter have asymmetric information about abatement costs, and the environmental damage depends on the stock of pollution. We thus extend to a dynamic framework previous studies in which...

We study the situation where firms' actions contribute to a stock externality. The regulator and firms have asymmetric information about serially correlated (abatement) costs. With price-based policies such as taxes, the regulator learns about the evolution of both stock and costs. This ability...
