Nicholas Muller is the Lester and Judith Lave Professor of Economics, Engineering, and Public Policy and works at the intersection of environmental policy and economics. His interdisciplinary research projects focus on estimating individual discount rates and risk preferences using historical pricing data, comparing air pollution and climate damages from electric vehicles to conventional vehicles, estimating air pollution damage from energy production, measuring the impact of transporting freight in the United State on air pollution and climate, and analyzing the inequality in market and augmented measures of income. He teaches microeconomics and environmental and natural resource economics and has published papers in the American Economic Review, Science, and Proceedings of the National Academies of Science.

Muller on health effects of reduced air pollution from COVID-19

EPP’s Nick Muller was interviewed by Pittsburgh Post-Gazette about a new study he co-authored about the impact of social distancing and stay-at-home months during the COVID-19 pandemic on air pollution. The study found that with reduced exposure to fossil fuel emissions from vehicles and power plants, premature mortality from air pollution was likely down 25 percent.
