There has been intense focus on the issue of how emissions allowances might be allocated under a potential federal cap-and-trade program. What fraction of the allowances should be auctioned out, as opposed to given out free? How much free allocation would be sufficient to preserve profits in...

We examine the relative attractions of a carbon tax, a “pure” cap-and-trade system, and a “hybrid” option (a cap-and-trade system with a price ceiling and/or price floor). We show that the various options are equivalent along more dimensions than often are recognized. In addition, we...

A key finding is that exogenous emissions pricing (whether through a carbon tax or through the hybrid option) has a number of attractions over pure cap and trade. Beyond helping prevent price volatility and reducing expected policy errors in the face of uncertainties, exogenous pricing helps...

Carbon taxes are a potential revenue source that could play a key role in major tax reform. This paper employs a numerical general equilibrium model of the United States to evaluate alternative tax reductions that could be financed by the revenues from a carbon tax. We consider a carbon tax that...

We examine the extent to which various environmental policy instruments meet major evaluation criteria, including cost-effectiveness, distributional equity, minimization of risk in the presence of uncertainty, and political feasibility. Instruments considered include emissions taxes, tradable...

Global climate change poses a threat to the well-being of humans and other living things through impacts on ecosystem functioning, biodiversity, capital productivity, and human health. This paper briefly surveys recent research on the economics of climate change, including theoretical insights...

Economists have tended to view emissions pricing (e.g., cap and trade or a carbon tax) as the most cost-effective approach to reducing greenhouse gas emissions. This paper offers a different view. Employing analytical and numerically solved general equilibrium models, the paper indicates...

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....
