Knowledge that Transforms

We estimate the supply-side effects of climate change on firm sales by exploiting variation in local average temperature across suppliers of the same client. A 1°C increase in temperature leads to a 2.5% decline in annual sales. This effect is nonlinear, with stronger effects among suppliers in regions with the largest temperature increases and in cooler regions. Manufacturing and heat-sensitive industries are more affected, consistent with a reduction in labor productivity and labor supply when local temperatures rise. Nondiversified and financially constrained firms are also more affected, supporting the importance of operational and financial flexibility in adapting to climate change.

We examine the incentives for mutual fund families to launch ESG funds. Our analyses reveal that introducing a new ESG fund leads to a significant increase in capital inflows to sibling non-ESG funds in the family. This flow spillover accounts for a significant portion of the monetary awards for families to offer ESG funds. We also find that spillover is stronger among retail funds and cannot be attributed to changes in the ESG profiles or abnormal returns of the sibling funds. Further evidence suggests that affect-based judgments, particularly the halo effect, are the key drivers of this spillover effect.

We find that the effect of political connections on tax planning depends on firms’ financial conditions. After increased political connections, financially unconstrained firms increase tax planning and spending on tax services, as documented in prior studies, whereas constrained firms decrease tax planning and spending on tax services. Moreover, decreases in tax planning are only present for constrained firms that obtain new bank loans and public debt and when the connected politicians serve on banking-related committees. Our results suggest that by facilitating access to external financing, political connections reduce financially constrained firms’ use of tax planning as an internal financing tool.

We examine whether and how firms use connected social media outlets to counteract negative coverage in traditional media. Employing a sample of Chinese listed firms with ties to social media outlets, we find that connected outlets portray firms more favorably than unconnected ones. Following unfavorable coverage in traditional media, connected outlets shift attention toward long-term prospects and promote favorable narratives, consistent with an optimism-shifting mechanism. The effect is more pronounced when firms have stronger incentives to stabilize stock prices and when managers face heightened career concerns. Our findings highlight the role of connected social media outlets in shaping corporate narratives.

We examine the effect of private equity buyouts on the environmental performance of U.S. fossil fuel power plants. Output-scaled CO 2 emissions are, on average, 4.2% lower after buyouts, predominantly because of fuel-saving improvements in production efficiency. Emission intensities decline more significantly following buyouts backed by pro-ESG private equity because of not only greater efficiency gains but also enhanced emission control. Our results suggest that while private equity firms are effective at implementing environmentally beneficial operational changes that also increase profitability, they do not have strong incentives to undertake environmentally beneficial changes that are privately costly, except for those with pro-ESG preferences.
