Climate Change and Adaptation in Global Supply-Chain Networks
This paper examines how physical climate risks affect firms' financial performance and operational risk management in global supply-chains. We document that weather shocks at supplier locations reduce the operating performance of suppliers and their customers. Further, customers respond to perceived changes in suppliers' climate-risk exposure: When realized shocks exceed ex-ante expectations, customers are 6-11% more likely to terminate existing supplier-relationships. Consistent with models of experience-based learning, this effect increases with signal strength and repetition, is ...

Firms’ Supply Chain Adaptation to Carbon Taxes
This paper studies how firms adjust input sourcing in response to climate policy. Using the EU Emissions Trading System (ETS) as a natural experiment and French product-level import and production data, we show that firms increasingly shifted imports of ETS-regulated inputs to non-EU countries over the 2010s as the policy became more stringent, indicating carbon leakage. This leakage is economically significant: the share of ETS-regulated products sourced from outside the EU rose by 4.3 percentage points after the ETS was implemented. Motivated by these empirical findings, we estimate a ...
