Despite serving as the principal basis of U.S. climate policy over the past two decades, corporate voluntary environmental programs have been subject to quite limited evaluation. The self-selection of participants—an essential element of such initiatives—poses particular challenges to...

Seminal work by Weitzman (1974) revealed that prices are preferred to quantities when marginal benefits are relatively flat compared to marginal costs. We extend this comparison to indexed policies, where quantities are proportional to an index, such as output. We find that policy preferences...

Technologies to reduce significantly fossil-fuel emissions currently are unavailable or only available at high cost. In light of this, the amount of research on the pace, direction, and benefits of environmentally friendly technological change has grown dramatically in recent years. This...

Quantity-based regulation with banking allows regulated firms to shift obligations across time in response to periods of unexpectedly high or low marginal costs. Despite its wide prevalence in existing and proposed emission trading programs, banking has received limited attention in past welfare...

Market-based policies to address fossil fuel-related externalities including climate change typically operate by raising the price of those fuels. Increases in energy prices have important consequences for a typical U.S. household that spent almost $4,000 per year on electricity, fuel oil,...

Decisions concerning environmental protection hinge on estimates of economic burden. Over the past 30 years, economists have developed and applied various tools to measure this burden. In this chapter, we present a taxonomy of costs along with methods for measuring those costs. At the broadest...

Given that technologies to significantly reduce fossil fuel emissions are currently unavailable or only available at high cost, technological change will be a key component of any long-term strategy to reduce greenhouse gas emissions. In light of this, the amount of research on the pace,...

The approach used to model technological change in a climate policy model is a critical determinant of its results. We provide an overview of the different approaches used in the literature, with an emphasis on recent developments regarding endogenous technological change, research and...

Economists have speculated that the welfare gains from technological innovation that reduces the future costs of environmental protection could be a lot more important than the "Pigouvian" welfare gains over time from correcting a pollution externality. If so, then a primary concern in the...
