Corporate Green Pledges
We identify corporate commitments for reductions of greenhouse gas emissions—green pledges—from news articles using a large language model. About 8% of publicly traded U.S. companies have made green pledges, and these companies tend to be larger and browner than those without pledges. Announcements of green pledges significantly and persistently raise stock prices, consistent with reductions in the carbon premium. Firms that make green pledges subsequently reduce their CO2 emissions. Our evidence suggests that green pledges are credible, have material new information for investors, and ...

The Green Corporate Bond Issuance Premium
We study a global panel of green and conventional bonds to assess the borrowing cost advantage at issuance for green bond issuers. We find that, on average, green bonds have a yield spread that is 8 basis points lower relative to conventional bonds. This borrowing cost advantage, or greenium, emerges as of 2019 and coincides with the growth of the sustainable asset management industry following EU regulation. Within this context, we find that the greenium is linked to two proxies of demand pressure, bond oversubscription and bond index inclusion. Moreover, while green bond governance appears ...

What are Large Global Banks Doing About Climate Change?
We review the "climate action plans" of Global Systemically Important Banks (GSIBs) and the progress they are making toward achieving them. G-SIBs have identified the drivers of climate risk and their transmission channels to credit and other risks. Additionally, some have started to measure and model these risks. While most GSIBs have committed to fully offsetting their emissions by mid-century, they are only beginning to measure financed emissions resulting from their loans and investments, which comprise the vast majority of their emissions. G-SIBs have also committed to increase green ...

Pricing Poseidon: Extreme Weather Uncertainty and Firm Return Dynamics
We investigate the uncertainty dynamics surrounding extreme weather events through the lens of option and stock markets by identifying market responses to the uncertainty regarding both potential hurricane landfall and subsequent economic impact. Stock options on firms with establishments exposed to the landfall region exhibit increases in implied volatility of 5-10 percent, reflecting impact uncertainty. Using hurricane forecasts, we show that landfall uncertainty and potential impact uncertainty are reflected in prices before landfall. We find no evidence that markets incorporate better ...

Green Stocks and Monetary Policy Shocks: Evidence from Europe
Policymakers and researchers worry that the low-carbon transition may be inadvertently delayed by higher global interest rates. To examine whether green investment is especially sensitive to interest rate increases, we consider the effect of unanticipated monetary policy changes on the equity prices of green and brown European firms. We find that brown firms, measured in terms of carbon emission levels or intensities, are more negatively affected than green firms by tighter monetary policy. This heterogeneity is robust to different monetary policy surprises, emission measures, econometric ...

Auto Finance in the Electric Vehicle Transition
Financing cost differentials tilt the calculus for households toward electric vehicles (EVs). Using 85 million observations on U.S. auto loans, we study households’ credit risk by engine type, seek to uncover the sources and ask if credit risk differentials are being priced. We find that EV borrowers default 29% less relative to internal combustion engine vehicle (ICEV) borrowers with a back-of-the-envelope value of $1,457 in lender savings. To disentangle selection from expost exposure to differential costs of running an EV, we implement a differential shock exposure by treatment model of ...

Leveraging the Disagreement on Climate Change: Theory and Evidence
We theoretically and empirically investigate how climate risks affect collateralized debt markets. First, we develop a debt model where agents have different beliefs over a long-run risk. In contrast with existing two-period competitive-equilibrium models, our infinite-horizon competitive-search model predicts more pessimistic agents are more likely to make leveraged investments on risky collateral assets. They also tend to use longer maturity debt contracts, which are more exposed to the long-run risk. Second, employing large data on real estate and mortgage transactions, combined with high ...

Up in Smoke: The Impact of Wildfire Pollution on Healthcare Municipal Finance
Wildfire smoke pollution is associated with significantly higher healthcare municipal borrowing costs, amounting to $250 million in realized interest costs for high-smoke counties in 2010–2019, and an estimated $570 million over the following 10 years. These costs are disproportionately higher in high-poverty or high-minority areas where there is more smoke-related uncompensated care. Out-of-state smoke is also associated with higher borrowing costs, suggesting poor wildfire management imposes externalities on nearby states. Our hospital-level analysis shows increases in asthma cases and ...
