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.

This paper develops a life-cycle model in which workers choose both consumption levels and job fatality risks, implying that the effect of age on the value of life is ambiguous. The empirical analysis of this relationship uses novel, age-dependent fatal and nonfatal risk variables. Workers' value of statistical life exhibits an inverted U-shaped relationship over workers' life cycle based on hedonic wage model estimates, age-specific hedonic wage estimates, and a minimum distance estimator. The value of statistical life for a 60-year old ranges from $2.5 million to $3.0 million -- less than half the value for 30 to 40-year olds.
