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...

How should environmental policy respond to economic fluctuations caused by persistent productivity shocks? This paper answers that question using a dynamic stochastic general equilibrium real business cycle model that includes a pollution externality. I first estimate the relationship between...

We assess the feasibility, optimality, and policy implications of Environmental, Social, and Corporate Governance (ESG)-linked or “green” lending in a credit market where banks incorporate such non-financial data in credit allocation decisions. We identify an asymmetric information problem:...
