Research question and approach
- Develops a continuous time heterogeneous agents model to study the impact of carbon pricing policy shocks on corporate default risk and the consequent transition dynamics.
- Derives a closed-form solution to corporate default probability based on firms' intertemporal optimization decisions.
- Explicitly characterizes the transition speed, enabling analytically tractable study of policy implications.
Key findings
- Carbon-intensive sectors face increased default risks.
- There are notable asymmetric effects within sectors.
- Higher carbon prices increase default risk but also induce faster transition towards the new post-shock steady state with a highly non-linear impact.
- Once a range of possible price shocks are accounted for, the increase in the cost of capital/risk premiums might be sharply different across sectors.
Calibration and scope
- The model is calibrated to different US corporate sectors to quantify the heterogeneous effects of carbon price shocks.
Policy implications and analytical contributions
- Provides an analytically tractable framework for assessing how carbon pricing policy shocks propagate to corporate default probabilities and transition dynamics.
- Highlights that the same carbon price shock can have sharply different implications for cost of capital/risk premiums across sectors because of heterogeneity and non-linear transition dynamics.
