Abstract
The ongoing debate concerning the ranking of taxes versus cap and trade for climate policy begins with Weitzman’s (1974) seminal slope-based criterion and concludes that taxes likely dominate quotas. We challenge this conclusion and the intuition behind it. Because technology shocks and pollution stocks are both persistent, a technology shock alters the intercepts of both the marginal damage and abatement cost curves. The ratio of these two intercept shifts is as important as the ratio of slopes in ranking policies. Technology innovations diffuse gradually, strengthening the importance of the ratio of intercept shifts. For plausible parameter combinations, quotas can dominate taxes.
期刊介绍：
The Journal of Environmental Economics and Management publishes theoretical and empirical papers devoted to specific natural resources and environmental issues. For consideration, papers should (1) contain a substantial element embodying the linkage between economic systems and environmental and natural resources systems or (2) be of substantial importance in understanding the management and/or social control of the economy in its relations with the natural environment. Although the general orientation of the journal is toward economics, interdisciplinary papers by researchers in other fields of interest to resource and environmental economists will be welcomed.
