Abstract: The American Recovery and Reinvestment Act included more than $90 billion in strategic clean energy investments intended to promote job creation and promote deployment of low-carbon technologies. In terms of spending, the clean energy package has been described as the nation’s “biggest energy bill in history.” To provide a preliminary assessment of the Recovery Act’s clean energy package, this paper reviews the rationale, design, and implementation of the act. The paper surveys the policy principles for clean energy stimulus and describes the process of crafting the clean energy package during the 2008–2009 Presidential Transition. Then, the paper reviews the initial employment, economic activity, and energy outcomes associated with these energy investments and provides a more detailed case study on the Recovery Act’s support for renewable power through grants and loan guarantees. The paper concludes with lessons learned.

Abstract: Because of the global commons nature of climate change, international cooperation among nations will likely be necessary for meaningful action at the global level. At the same time, it will inevitably be up to the actions of sovereign nations to put in place policies that bring about meaningful reductions in the emissions of greenhouse gases. Due to the ubiquity and diversity of emissions of greenhouse gases in most economies, as well as the variation in abatement costs among individual sources, conventional environmental policy approaches, such as uniform technology and performance standards, are unlikely to be sufficient to the task. Therefore, attention has increasingly turned to market-based instruments in the form of carbon-pricing mechanisms. We examine the opportunities and challenges associated with the major options for carbon pricing: carbon taxes, cap-and-trade, emission reduction credits, clean energy standards, and fossil fuel subsidy reductions.

Abstract: Emissions of greenhouse gases linked with global climate change are affected by diverse aspects of economic activity, including individual consumption, business investment, and government spending. An effective climate policy will have to modify the decision calculus for these activities in the direction of more efficient generation and use of energy, lower carbon intensity of energy, and – more broadly – a more carbon-lean economy. The only approach to doing this on a meaningful scale that would be technically feasible and cost-effective is carbon pricing, that is, market-based climate policies that place a shadow-price on carbon dioxide emissions. We examine alternative designs of three such instruments – carbon taxes, cap-and-trade, and clean energy standards. We note that the U.S. political response to possible market-based approaches to climate policy has been and will continue to be largely a function of issues and structural factors that transcend the scope of environmental and climate policy.

Abstract: This paper provides an exhaustive review of critical issues in the design of climate mitigation policy by pulling together key findings and controversies from diverse literatures on mitigation costs, damage valuation, policy instrument choice, technological innovation, and international climate policy. We begin with the broadest issue of how high assessments suggest the near and medium term price on greenhouse gases would need to be, both under cost-effective stabilization of global climate and under net benefit maximization or Pigouvian emissions pricing. The remainder of the paper focuses on the appropriate scope of regulation, issues in policy instrument choice, complementary technology policy, and international policy architectures.

Abstract: In this paper, we discuss the design of carbon dioxide (CO2) taxes at the domestic and international level and the choice of taxes versus a cap-and-trade system. A strong case can be made fortaxes on uncertainty, fiscal, and distributional grounds, though this critically hinges on policy specifics and how revenues are used. The efficient near-term tax is at least $5–$20 per ton of CO2 and the tax should be imposed upstream with incentives for downstream sequestration and abatement of other greenhouse gases. At the international level, a key challenge is the possibility that emissions taxes might be undermined through offsetting changes in other energy policies.

Abstract: Over the coming decades, the cost of U.S. climate change policy likely will be comparable to the total cost of all existing environmental regulation—perhaps 1–2 percent of national income. In order to avoid higher costs, policy efforts should create incentives for firms and individuals to pursue the cheapest climate change mitigation options over time, among all sectors, across national borders, and in the face of significant uncertainty. Well-designed national greenhouse gas mitigation policies can serve as the foundation for global efforts and as an example for emerging and developing countries. We present six key policy design issues that will determine the costs, cost-effectiveness, and distributional impacts of domestic climate policy: program scope, cost containment, offsets, revenues and allowance allocation, competitiveness, and R&D policy. We synthesize the literature on these design features, review the implications for the ongoing policy debate, and identify outstanding research questions that can inform policy development.

Abstract: Revealed preference evidence, especially based on wage-risk tradeoffs in the labor market, provides the primary empirical basis for analyses of the value of statistical life (VSL). This market evidence also provides guidance on how VSL varies with age. While labor market studies have generated conflicting evidence—some showing that VSL rises with age and others showing that VSL declines with age—more refined estimates that take into account the age variation in job fatality risks or life-cycle patterns of consumption show an inverted-U relation between the VSL and age. The value of a statistical life year shows a similar pattern and is not time-invariant. Applying estimates of the VSL-age relationship to an analysis of the Clear Skies initiative illustrates the implications of recognizing the age-VSL relationship.

Abstract: To resolve the theoretical ambiguity in the effect of age on the value of statistical life (VSL), this article uses a novel, age-dependent fatal risk measure to estimate age-specific hedonic wage regressions. VSL exhibits an inverted-U shaped relationship with age. In the year 2000 cross-section, workers’ VSL rises from $3.2 million (ages 18–24), to $9.9 million (35–44), and declines to $3.8 million (55–62). Controlling for birth-year cohort effects in a minimum distance estimator yields a peak VSL of $7.8 million at age 46 and flattens the VSL-age relationship. The value of statistical life-year also follows an inverted-U shape with age.

Abstract: This paper explores the relationships among economic development, energy consumption, and carbon dioxide (CO2) emissions by focusing on a set of advanced economies, the U.S. states. Energy consumption and emissions grew 50–60 percent on average over the 1960–1999 period. The states’ per capita energy consumption and emissions have grown on average 2 percent annually as income and population growth have outpaced improvements in energy intensity of output and carbon intensity of energy. The energy consumption income elasticity is positive but decreasing in income, although energy production takes an inverted-U shape, reflecting the electricity imports among high income states. The standard CO2 measure, corresponding to energy production, is characterized by an inverted-U environmental Kuznets curve. Adjusting emissions for interstate electricity trade yields an emissions–income relationship that peaks and plateaus. The carbon intensity of energy declines in income for total energy consumption and the industrial, residential, and commercial sectors.

Abstract: This article develops the first measures of age-industry job risks to examine the age variations in the value of statistical life. Because of the greater risk vulnerability of older workers, they face flatter wage-risk gradients than younger workers, which we show to be the case empirically. Accounting for this heterogeneity in hedonic market equilibria leads to estimates of the value of statistical life-age relationship that follows an inverted-U shape. The estimates of the value of statistical life range from $6.4 million for younger workers to a peak of $9.0 million for those age 35-44, and then a decline to $3.7 million for those age 55-62. The decline of the estimated VSL with age is consistent with there being some senior discount in the Clear Skies Initiative analysis.

Abstract: Decisionmakers considering policies to mitigate climate change will benefit from information about current and future distributions of carbon dioxide (CO2) emissions. Examining the emissions dynamics of advanced economies that have experienced income convergence could provide insights about how distributions of country-level emissions may evolve over time if country-level incomes eventually undergo some convergence. This paper addresses the question of whether income convergence is sufficient for per capita CO2 emissions convergence by focusing on a set of advanced economies, the U.S. states. I undertake a variety of cross-sectional and stochastic convergence tests with two novel measures of 1960–1999 state-level CO2 emissions per capita—production (pre-electricity trade) CO2 and consumption (post-electricity trade) CO2—and with income per capita. Although incomes continue to converge, I find stark divergence in production CO2 per capita and no evidence of convergence for consumption CO2 per capita. Forecasts of future distributions show little convergence in emissions.

Abstract: Understanding and considering the distribution of per capita carbon dioxide (CO2) emissions is important in designing international climate change proposals and incentives for participation. I evaluate historic international emissions distributions and forecast future distributions to assess whether per capita emissions have been converging or will converge. I find evidence of convergence among 23 member countries of the Organisation for Economic Co-operation and Development (OECD), whereas emissions appear to be diverging for an 88-country global sample over 1960–2000. Forecasts based on a Markov chain transition matrix provide little evidence of future emissions convergence and indicate that emissions may diverge in the near term. I also review the shortcomings of environmental Kuznets curve regressions and structural models in characterizing future emissions distributions.

Abstract: We critically review the Kyoto Protocol and thirteen alternative policy architectures for addressing the threat of global climate change. We employ six criteria to evaluate the policy proposals: environmental outcome, dynamic efficiency, cost effectiveness, equity, flexibility in the presence of new information, and incentives for participation and compliance. The Kyoto Protocol does not fare well on a number of criteria, but none of the alternative proposals fare well along all six dimensions. We identify several major themes among the alternative proposals: Kyoto is “too little, too fast”; developing countries should play a more substantial role and receive incentives to participate; implementation should focus on market-based approaches, especially those with price mechanisms; and participation and compliance incentives are inadequately addressed by most proposals. Our investigation reveals tensions among several of the evaluative criteria, such as between environmental outcome and efficiency, and between cost-effectiveness and incentives for participation and compliance.
