We propose a new methodology to build portfolios that hedge the economic and financial risks from climate change. Our quantity-based approach exploits information on how mutual fund managers trade in response to idiosyncratic changes in their climate risk beliefs. We exploit two types of...

This paper studies whether green investors can influence corporate greenhouse gas emissions through capital markets, either by divesting their stock and limiting polluters' access to capital, or holding polluters' stock and engaging with management. We focus on public pension funds, classifying...

Shared socioeconomic pathways (SSPs) are perhaps the most influential economic policy analyses today. My paper evaluates their development, natural associations, logical consequences, and economic identification. All five SSP baseline scenarios are predicting scenarios that historical...

The durability of the transportation capital stock slows down the pace of decarbonization since newer vintages feature cutting-edge technology. If older vintages were to be retired sooner, the social cost of travel would decline. This paper analyzes and explores the viability of a potential...

Estimating the cost to society from a ton of carbon dioxide (CO2) released into the atmosphere requires connecting a model of the climate system with a representation of the economic and social effects of changes in climate, as well as the valuation and aggregation of diverse, uncertain impacts...

Current policies directed at mitigating global warming appear unlikely to prevent temperatures from rising to levels that would trigger a precipitous increase in the costs of climate change. Various attempts at international cooperation to avoid this outcome have failed. Why is this problem so...

Reductions in greenhouse gas emissions are a global public good, which makes it efficient to act globally when addressing this challenge. We lay out several reasons that high-income countries seeking to mitigate climate change might have greater impact if they invest their resources in...

This paper provides stated preference (SP) estimates of the average social cost of carbon (ASCC) for use in evaluation of the benefits and costs of climate policy. Based on a U.S. nationally representative survey, we find an average individual willingness-to-pay (WTP) of $1,116 per year to keep...

We investigate the short- and long-term effects of a natural gas boom in an economy where energy can be produced with coal, natural gas, or clean sources and the direction of technology is endogenous. In the short run, a natural gas boom reduces carbon emissions by inducing substitution away...

Climate change is generating demonstrable harm around the world. Political and legal efforts have sought to associate climate impacts with specific emissions, including in recent international policy discussion of Loss and Damage (L&D). However, no quantitative definition of L&D exists, nor does...
