Abstract
We construct measures of firms' beliefs about climate regulation, plans for future abatement, and current emissions mitigation from responses to the Carbon Disclosure Project. These measures vary in a pronounced, distinctive fashion around the Paris announcement. A dynamic model of a representative firm exposed to a future carbon levy, trading-off mitigation against capital growth, facing convex abatement adjustment costs does not fit the data; but a two-firm model with cross-firm information asymmetry and reputational externalities does. Out-of-sample, the model predicts reversals following the US exit from the Paris agreement. We conclude that abatement is strongly affected by firms' beliefs about climate regulation, and cross-firm interactions amplify the impact of regulation.
