Asset managers face increasing pressure to only hold firms that meet net-zero carbon emissions targets. We model how these mandates incentivize firms to address the global-warming externality through investments in decarbonization capital. A firm that invests receives a lower cost of capital by...

We estimate a model of damage to corporate earnings from COVID-19. An unexpected pandemic lowers current earnings due to costly mitigation and reduces growth rates. Damage depends on the expected arrival of a vaccine that reverts earnings to normal. Using this model, we infer from analysts'...

We develop a model of pandemic risk management and firm valuation. We introduce aggregate transmission shocks into an epidemic model and link valuations to infections via an asset-pricing framework with vaccines. Infections lower earnings growth but firms can mitigate damages. We estimate a...

We develop a model of pandemic risk management and firm valuation. We introduce aggregate transmission shocks into an epidemic model and link valuations to infections by using an asset-pricing framework that accounts for vaccines. Infections lower earnings growth but firms can mitigate damages....

Emissions control cannot address the consequences of global warming for weather disasters until decades later. We model regional-level mitigation, which reduces aggregate disaster risks to capital stock in the interim. Unexpected disaster arrivals increase belief regarding the adverse...

In lieu of carbon taxes to address global warming, sustainable investment mandates are proposed to incentivize firms to achieve net-zero emissions. With underspending on mitigation due to externalities, we model the welfare consequences of these investments in firms that qualify by spending...
