Abstract
En 中文
This paper investigates how firms manage supplier disclosures to project a greener supply chain. We show that firms selectively reveal relationships with high-ESG suppliers while withholding ties to low-ESG ones. A shift in the supplier’s environmental score from the 10th to the 90th percentile increases disclosure probability by 4.4% relative to the mean disclosure rate. Our analysis suggests this selective disclosure reflects greenwashing rather than genuine communication of supply-chain ESG improvements. In a U.S. subsample, firms are more likely to disclose green suppliers in the 10-K Business section and ESG reports, while low-ESG suppliers appear more frequently in the 10-K Risk Factors section. Strategic disclosure declines as environmental transparency regulations tighten. Finally, firms that strategically disclose green suppliers experience higher short-term stock returns, though these effects diminish over time. Our results highlight the importance of supply chain environmental disclosure and its potential to reduce capital misallocation.
