Nearly all discussions about the appropriate consumption discount rate for climate-change policy evaluation assume that a single discount rate concept applies. We argue that two distinct concepts and associated rates apply. We distinguish a social-welfare-equivalent discount rate appropriate for...

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 bring out...

Economists have tended to view cap and trade (or, more generally, emissions pricing) as more cost-effective than a clean energy standard (CES) for the purpose of reducing greenhouse gas emissions associated with electricity generation. This stems in part from the finding that, in terms of...

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....

This paper examines the implications of alternative allowance allocation designs under a federal cap-and-trade program to reduce emissions of greenhouse gases. We focus on the impacts on industry profits and overall economic output, employing a dynamic general equilibrium model of the U.S....

Fourteen U.S. states recently pledged to adopt limits on greenhouse gases (GHGs) per mile of light-duty automobiles. Previous analyses predicted this action would significantly reduce emissions from new cars in these states, but ignored possible offsetting emissions increases from policy-induced...

In an open economy, savings- and investment-promoting policies may have very different effects on the capital account and on the viability of export-oriented and import-competing industries. The nature of the effects is often ambiguous in analytical models. This paper employs a simulation model...

There is a growing recognition among public finance economists of the inappropriateness of closed economy models for analyzing alternative U.S. tax policies. In response to this, this paper reports on four different external sector specifications for the Fullerton-Shoven-Whalley general...

This paper shows that the usual excess-burden triangle' formula performs poorly when used to assess the excess burden from taxes on intermediate inputs or consumer goods, and derives a practical alternative to this formula. We use an analytically tractable general equilibrium model to reveal how...
