  1. Carbon Pricing and COVID-19.Kian Mintz-Woo, Francis Dennig, Hongxun Liu & Thomas Schinko - forthcoming - Climate Policy.
    [Article currently freely available to all at the DOI link below] A question arising from the COVID-19 crisis is whether the merits of cases for climate policies have been affected. This article focuses on carbon pricing, in the form of either carbon taxes or emissions trading. It discusses the extent to which relative costs and benefits of introducing carbon pricing may have changed in the context of COVID-19, during both the crisis and the recovery period to follow. In several ways, (...)

    The Social Cost of Carbon: Valuing Inequality, Risk, and Population for Climate Policy.Marc Fleurbaey, Maddalena Ferranna, Mark Budolfson, Francis Dennig, Kian Mintz-Woo, Robert Socolow, Dean Spears & Stéphane Zuber - 2019 - The Monist 102 (1):84-109.
    We analyze the role of ethical values in the determination of the social cost of carbon, arguing that the familiar debate about discounting is too narrow. Other ethical issues are equally important to computing the social cost of carbon, and we highlight inequality, risk, and population ethics. Although the usual approach, in the economics of cost-benefit analysis for climate policy, is confined to a utilitarian axiology, the methodology of the social cost of carbon is rather flexible and can be expanded (...)

    Impact of Population Growth and Population Ethics on Climate Change Mitigation Policy.Mark Budolfson, Noah Scovronick, Francis Dennig, Marc Fleurbaey, Asher Siebert, Robert H. Socolow, Dean Spears & Fabian Wagner - 2017 - Pnas 114 (46).
    Future population growth is uncertain and matters for climate policy: higher growth entails more emissions and means more people will be vulnerable to climate-related impacts. We show that how future population is valued importantly determines mitigation decisions. Using the Dynamic Integrated Climate-Economy model, we explore two approaches to valuing population: a discounted version of total utilitarianism (TU), which considers total wellbeing and is standard in social cost of carbon dioxide (SCC) models, and of average utilitarianism (AU), which ignores population size (...)

    Inequality, Climate Impacts on the Future Poor, and Carbon Prices.Mark Budolfson, Francis Dennig, Marc Fleurbaey, Asher Siebert & Robert H. Socolow - 2015 - Pnas 112 (52).
    Integrated assessment models of climate and the economy provide estimates of the social cost of carbon and inform climate policy. We create a variant of the Regional Integrated model of Climate and the Economy (RICE)—a regionally disaggregated version of the Dynamic Integrated model of Climate and the Economy (DICE)—in which we introduce a more fine-grained representation of economic inequalities within the model’s regions. This allows us to model the common observation that climate change impacts are not evenly distributed within regions (...)

    Optimal Climate Policy and the Future of World Economic Development.Mark Budolfson, Francis Dennig, Marc Fleurbaey, Noah Scovronick, Asher Siebert, Dean Spears & Fabian Wagner - 2019 - The World Bank Economic Review 33.
    How much should the present generations sacrifice to reduce emissions today, in order to reduce the future harms of climate change? Within climate economics, debate on this question has been focused on so-called “ethical parameters” of social time preference and inequality aversion. We show that optimal climate policy similarly importantly depends on the future of the developing world. In particular, although global poverty is falling and the economic lives of the poor are improving worldwide, leading models of climate economics may (...)

    The Comparative Importance for Optimal Climate Policy of Discounting, Inequalities and Catastrophes.Mark Budolfson, Francis Dennig, Marc Fleurbaey & Asher Siebert - 2017 - Climatic Change 145.
    Integrated assessment models (IAMs) of climate and the economy provide estimates of the social cost of carbon and inform climate policy. With the Nested Inequalities Climate Economy model (NICE) (Dennig et al. PNAS 112:15,827–15,832, 2015), which is based on Nordhaus’s Regional Integrated Model of Climate and the Economy (RICE), but also includes inequalities within regions, we investigate the comparative importance of several factors—namely, time preference, inequality aversion, intraregional inequalities in the distribution of both damage and mitigation cost and the damage (...)

    Human Health and the Social Cost of Carbon: A Primer and a Call to Action.Mark Budolfson, Noah Scovronick, Valeri N. Vasquez, Frank Errickson, Francis Dennig, Antonio Gasparrini, Shakoor Hajat & Dean Spears - 2019 - Epidemiology 30 (5).
    Over the past few decades, we have improved our understanding of the health impacts of climate change.1 Although many public health researchers have contributed to this knowledge, relatively few are aware of how their work may relate to the social cost of carbon. The social cost of carbon is a core economic concept in climate policy and one that can—and should—benefit directly from research produced by the public health community. The concept’s importance was recently highlighted by this past year’s Nobel (...)

    The Impact of Human Health Co-Benefits on Evaluations of Global Climate Policy.Noah Scovronick, Mark Budolfson, Francis Dennig, Frank Errickson, Marc Fleurbaey, Wei Peng, Robert H. Socolow, Dean Spears & Fabian Wagner - 2019 - Nature Communications 2095 (19).
    The health co-benefits of CO2 mitigation can provide a strong incentive for climate policy through reductions in air pollutant emissions that occur when targeting shared sources. However, reducing air pollutant emissions may also have an important co-harm, as the aerosols they form produce net cooling overall. Nevertheless, aerosol impacts have not been fully incorporated into cost-benefit modeling that estimates how much the world should optimally mitigate. Here we find that when both co-benefits and co-harms are taken fully into account, optimal (...)
