Climate Policy Design Under Uncertainty
No full textThe uncertainty surrounding both costs and benefits associated with global climate change mitigation creates enormous hurdles for scientists, stakeholders, and decisionmakers. A key issue is how policy choices balance uncertainty about costs and benefits. This balance arises in terms of the time path of mitigation efforts as well as whether those efforts, by design, focus on effort or outcome. This paper considers two choices—price versus quantity controls and absolute versus relative/intensity emissions limits—demonstrating that price controls and intensity emissions limits favor certainty about cost over climate benefits and future emissions reductions. The paper then argues that in the near term, this favoritism is desired.carbon, climate, policy, intensity, global warming, uncertainty, price, quantity
Endogenizing Technological Change: Matching Empirical Evidence to Modeling Needs
No full textTechnologies 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 research includes empirical estimates of these effects and modeling exercises designed to simulate endogenous technological change in response to climate policy. Unfortunately, few attempts have been made to connect these two streams of research. This paper attempts to bridge that gap, reviewing both the empirical and modeling literature on technological change. Our goal is to provide an agenda for how both empirical and modeling research in these areas can move forward in a complementary fashion. In doing so, we discuss how models used for policy evaluation can better capture empirical phenomena and how empirical research can better address the needs of models used for policy evaluation.endogenous technological change, climate change, CGE modeling
Economics versus Climate Change
No full textThis paper argues against the common-sense conclusion that climate change demands a global market-based solution, such as international emissions trading. First, current experience suggests global cooperation is not necessary for initial mandatory actions. Second, when domestic targets vary across nations, there are a variety of reasons why international emissions trading, even though it creates aggregate economic gains for all nations, may not be desirable. These reasons include concerns over legitimizing target variations for future negotiations, real and perceived consequences of capital flows across nations, and distributional impacts within nations. Finally, the underlying need for global technology solutions suggests domestic mitigation policies that balance clear emissions price signals, incentives for technology development and deployment, and mechanisms to finance deployment to developing countries. International efforts, in turn, might focus on encouraging these domestic actions, facilitating the developing country investment mechanisms, and providing credible reviews of national action.climate, change, international, treaty, Kyoto, emissions trading

The Case for Intensity Targets
No full textWhile the rest of the world has pursued absolute emissions limits for greenhouse gases, the Bush administration has proposed an alternative policy formulation based, among other things, on reducing emissions intensity—that is, emissions per dollar of real gross domestic product. Critics of this formulation have denounced the general idea of an intensity-based emissions target, along with its voluntary nature and weak targets. This raises the question of whether intensity-based emissions limits, distinct from the other features of the Bush initiative, offer a useful alternative to absolute emissions limits. This paper makes the case that they do, based on how emissions targets are framed. The argument draws on four key observations: greenhouse gas emissions will continue to rise over the near term, absolute targets emphasize zero or declining emissions growth while intensity targets do not, developing countries’ economic development is integrally tied to emissions growth for the foreseeable future, and intensity targets need not be any more complicated to administer than absolute targets.carbon, climate, policy, intensity, global warming

Calculating the Cost of Environmental Regulation
No full textDecisions 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 paper, developed as a chapter for the Handbook of Environmental Economics, we present a taxonomy of costs along with methods for measuring those costs. At the broadest level, we distinguish between partial and general equilibrium costs. Partial equilibrium costs represent the burden directly borne by the regulated entity (firms, households, government), including both pecuniary and nonpecuniary expenses, when prices are held constant. General equilibrium costs reflect the net burden once all good and factor markets have equilibrated. In addition to partial equilibrium costs, these general equilibrium costs include welfare losses or gains in markets with preexisting distortions, welfare losses or gains from rebalancing the government's budget constraint, and welfare gains from the added flexibility of meeting pollution constraints through reductions in the use of higher-priced, pollution-intensive products. In addition to both partial and general equilibrium costs, we also consider the distribution of costs across households, countries, sectors, subnational regions, and generations. Despite improvements in our understanding of cost measurement, we find considerable opportunity for further work and, especially, better application of existing methods.social cost, cost-benefit, cost-effectiveness, environmental regulation
The EU Emissions Trading Directive: Opportunities and Potential Pitfalls
No full textThe European Union is on the verge of establishing an emissions trading program ten times the size of the Acid Rain trading program in the United States. Its design takes advantage of many lessons from existing experience with trading programs, as well as economic theory, and innovates in important ways. While we view this as an impressive development, concerns about equity, enforcement, and efficiency remain. Specifically, a lack of data and weaker environmental institutions in some EU Member States raises questions about both allowance allocations and compliance and enforcement. Although much attention has focused on whether prices will be “too low” in the first phase of the program, a greater risk is that uncertainty about program elements, technology and behavioral response, and external events could create volatile markets and costly compliance in the second phase. Regardless of outcome, the EU trading system will be influential in future international efforts to reduce greenhouse gases.European Union, climate change, emissions trading
Climate Change Catastrophes
No full textMost studies that compare price and quantity controls for greenhouse gas emissions under uncertainty find that price mechanisms perform substantially better. In these studies, the benefits from reducing emissions are proportional to the level of reductions, and such linear benefits strongly favor price policies (Weitzman 1974). Catastrophic damages, however, challenge that intuition as consequences become highly nonlinear. Catastrophe avoidance offers huge benefits, and incremental adjustments on either side of the associated threshold are relatively unimportant, suggesting a strong preference for quantity controls. This paper shows that with catastrophic damages, both price and quantity mechanisms offer large gains over the business-as-usual alternative, and the difference between policies is never more than 10%. Catastrophe avoidance is much more important than efficient catastrophe avoidance. Although previous studies favoring price policies in the presence of uncertainty have worried that catastrophes would reverse their results, this analysis indicates that such concerns are not borne out.climate change, global warming, prices versus quantities, stock externalities, integrated assessment, uncertainty
