In a market subject to environmental regulation, a firm's strategic behavior affects the production and emissions decisions of all firms. If firms are regulated by a Pigouvian tax, changing emissions will not affect the marginal cost of polluting. However, under a tradable permits system, the...

Carbon taxation is a widely proposed and in some countries already adopted means to limit anthropogenic climate change. This paper studies carbon taxation using an 18-region, 80- period overlapping generations model. We focus on carbon policy that delivers present and future mankind the highest...

Experiences in real-world pollution markets suggest that firms make persistent errors in forecasting allowance and credit prices that inform their investment decisions. The residual uncertainty characterizing allowance and credit trading means that pollution markets may fail to deliver...

Policy makers often express concern about the impact of carbon taxes on employment and GDP. Focusing on European countries that have implemented carbon taxes over the past 30 years, we estimate the macroeconomic impacts of these taxes on GDP and employment growth rates for various specifications...

The Mapping Carbon Pricing Initiatives Report maps existing and emerging carbon pricing initiatives around the world. It does not provide a quantitative, transaction-based analysis of the international carbon market since current market conditions invalidate any attempt to undertake such an...

Significant progress in carbon pricing has been made over the last ten years. In 2015, about 40 national and over 20 subnational jurisdictions, representing almost a quarter of global greenhouse gas emissions (GHG), are putting a price on carbon. Together, the carbon pricing instruments in these...

This paper develops a simple model of a polluting industry and an innovating firm. The polluting industry is faced with regulation and costly abatement. Regulation may be taxes or marketable permits. The innovating firm invests in R&D and develops technologies which reduce the cost of pollution...

In recent years, cases in which state governments chose to override federal environmental regulation with tighter regulations of their own have become increasingly common, even for pollutants that have substantial spillovers across states. This paper argues that this change arose at least in...

A politically realistic approach to environmental policy seems to require avoiding significant profit-losses in major pollution-related industries. The government can avoid such losses by freely allocating some emissions permits or by exempting some inframarginal emissions from a pollution tax....
