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.

重新评估税收与数量

关于气候政策中税收与上限和交易的排序问题，目前的争论始于 Weitzman（1974 年）的开创性斜坡标准，其结论是税收可能优先于配额。我们对这一结论及其背后的直觉提出了质疑。由于技术冲击和污染存量都是持续存在的，因此技术冲击会改变边际损害曲线和减排成本曲线的截距。这两种截距移动的比率与斜率比率一样，对政策排序具有重要意义。技术创新会逐渐扩散，从而加强了截距移动比率的重要性。在参数组合合理的情况下，配额可能会优先于税收。

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.
