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...

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...

Fourteen U.S. states recently pledged to adopt limits on automobile greenhouse gases (GHGs) per mile in an effort to reduce GHG emissions. We show that, because of interactions between this effort and the federal CAFE standard, 70-80 percent of the emissions reductions from new cars in adopting...

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...

This paper employs analytical and numerical general equilibrium models to examine the optimal setting of environmental taxes in the presence of pre-existing distortionary taxes. Both models indicate, contrary to what several analysts have suggested, that the optimal environmental tax rate in...

Using analytical and numerical general equilibrium models, we show that pre-existing factor taxes produce a "tax-interaction effect" that substantially increases the costs of pollution taxes and quotas. Under policies that raise revenue and recycle it through cuts in marginal factor tax rates,...

This paper examines the choice between revenue-raising and non-revenue-raising instruments for environmental protection in a second-best setting with pre-existing factor taxes. We find that interactions with pre-existing taxes fundamentally influence the costs of regulation and seriously...

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...

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....

Many pollution-related industries wield strong political influence and can effectively veto policy initiatives that would harm their profits. A politically realistic approach to environmental policy therefore seems to require the alleviation of significant profitlosses to these industries. The...
