  We study clean energy production subsidies in a quantitative climate–economy model. Clean energy production subsidies decrease carbon emissions if and only if they lower the marginal product of dirty energy. The constrained-efficient production subsidy equals the marginal external cost of dirty energy multiplied by the marginal impact of clean energy production on dirty energy production. With standard functional forms, two factors determine the impact of clean energy production subsidies on dirty energy use: the elasticity of substitution between clean and dirty energy and the price elasticity of demand for energy services. With some commonly used parameter values, subsidies on clean energy production increase carbon emissions and decrease welfare relative to laissez faire. With greater substitutability between clean and dirty energy, the production tax credits in the Inflation Reduction Act can generate modest emissions reductions. Even in this more optimistic scenario, a clean energy production subsidy generates significantly higher emissions and lower welfare than a tax on dirty energy.

  Policymakers’ imperfect knowledge about firms’ abatement costs leads to inefficient regulation, reducing the welfare gains from carbon markets around the world. We introduce a “smart” cap and trade system that eliminates these costs. This cap responds endogenously to technology or macroeconomic shocks, relying on the market price of certificates to aggregate information. It allows policy makers to modify existing institutions to achieve more efficient emissions reductions. The paper also showsthat the slow diffusion of technology innovationstypically makesthe optimal carbon price a much steeper function of emissions than suggested by the Social Cost of Carbon.

  I study optimal carbon taxation in an analytic quantitative integrated assessment model (IAM) that links IAM components, parametric assumptions, and calibration approaches directly to their policy impacts. I show how temperature’s tax impact differs from that of previously analytically modeled carbon dynamics. Novel to analytic IAMs are a general economy, energy sectors including capital, varying degrees of substitutability across energy sources, an approximation of capital persistence, objective functions that include CES preferences and population weighting, and an explicit model of the greenhouse effect and ocean-atmosphere temperature dynamics. The paper enables economists to develop better-informed opinions about the social cost of carbon. (JEL H23, H43, Q54, Q58)
