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...

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...

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 between a social-welfare-equivalent discount rate...

This paper estimates the welfare costs of the main medium-term options for significantly reducing U.S. energy-related carbon dioxide (CO2) emissions, including carbon taxes and cap-and-trade systems applied economy-wide and to the power sector only, and an emissions rate standard for power...

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 (rSW)...

This paper examines how much carbon emissions from the electricity industry would decrease in response to a carbon price. We show how both carbon prices and cheap natural gas reduce, in a nearly identical manner, the historic cost advantage of coal-fired power plants. The shale revolution has...

In this paper, we develop a methodology for estimating marginal emissions of electricity demand that vary by location and time of day across the United States. The approach takes account of the generation mix within interconnected electricity markets and shifting load profiles throughout the...

This paper reviews the literature on the relationship between climate and the energy sector. In particular, we primarily discuss empirical papers published in peer-reviewed economics journals focusing on how climate affects energy expenditures and consumption. Climate will affect energy...

Unreliable inputs to production, particularly those that are difficult to store, can significantly limit firms' productivity, leading them to react in a number of ways. This paper uses a panel of 23,000 energy-intensive, Chinese firms from 1999 to 2004 to examine how firms responded to severe...
