Climate Inequality: Carbon Capture for Redistribution, with Manuel Macera @Universidad Torcuato Di Tella. (Paper). We study optimal climate policy in a global economy where regions differ in wealth and climate vulnerability. Carbon emissions from production lead to output losses, and there is technology for emissions absorption. We provide an aggregation result: the model with heterogeneity can be cast into a representative region economy with a different discount factor and damage function. This result offers a simple rule to account for inequality in the design of optimal climate policy. We show that wealthier regions should bear more responsibility for carbon capture to cleanse the atmosphere, and that inequality per se does not entail a compromise on climate goals. As inequality increases, a more stringent climate policy is efficient, utilizing regional carbon capture as a means of redistribution across regions. Conversely, if carbon capture must be uniform across regions, optimal global climate policy implies higher emissions and reduced carbon capture, undermining overall effectiveness. An important insight is that carbon capture can serve as a redistribution tool when direct lump-sum transfers between unequal regions are not feasible.

Unequal Climate Policy in an Unequal World, with Daniel Carroll @Federal Reserve Bank of Cleveland and Sewon Hur @Federal Reserve Bank of Dallas (Paper). We study the link between household inequality and carbon taxes. First, using detailed household expenditure and embodied emissions data, we document that low-income household expenditures have higher embodied emissions per dollar than that of high-income households, suggesting that a carbon tax may be regressive. Second, using a simple climate-economy model with unequal households, we show that when the planner has access to a full set of tax and transfer instruments, the optimal carbon tax follows the Pigouvian rule and is the same tax that would result from a representative agent framework. However, when the planner is not allowed to distribute resources across agents, the constrained optimal carbon tax is heterogeneous: higher income households are taxed at a higher rate because of their lower marginal utility. When the planner is further limited to uniform carbon taxes across agents, we show that the uniform constrained optimal carbon tax deviates from the Pigouvian rule and is lower than the unconstrained optimal carbon tax. Finally, we embed the simple climate-economy into a standard incomplete markets model to quantify the effectiveness of these policies in reducing carbon emissions and their distributional consequences.

Needed: a Price for Carbon Capture. Submitted. This paper presents a macroeconomic framework for carbon markets. I set up a global climate-economy with carbon-intensive energy inputs, renewable energy, natural carbon sinks, and a carbon capture technology to show that (i) within a comprehensive carbon pricing system, a carbon tax alone implements any given path of carbon emissions; (ii) `additionality' is not a property of the optimal carbon pricing system; (iii) without a carbon tax, renewable subsidies, preservation of carbon sinks and a price for carbon capture are needed.
