Government policies that are not intended to address environmental concerns can nonetheless distort prices and affect firms' emissions. We present an analytical general equilibrium model to study the effect of distortionary subsidies on factor prices and on environmental outcomes. We model an...

Solar geoengineering (SGE) can combat climate change by directly reducing temperatures. Both SGE and the climate itself are surrounded by great uncertainties. Implementing SGE affects learning about these uncertainties. We model endogenous learning over two uncertainties: the sensitivity of...

Empirical evidence suggests that individual choices often display behavioral anomalies, like time-inconsistent preferences. For example, a household's preferences at the time of purchase of energy-intensive durable goods like cars and appliances may differ from its preferences later on,...

"When consumers exhibit present bias and are time-inconsistent, the standard solution to market failures caused by externalities-Pigouvian pricing-is suboptimal. I investigate policies aimed at externalities for time-inconsistent consumers. Welfare-maximizing policy in this case includes an...
