We investigate whether U.S. House representatives and their staff seek financial information from constituent firms to inform their legislative decisions. We exploit shifts in U.S. congressional districts (i.e., the reconfiguration of federal district lines or redistricting) that introduce new constituent firms to legislators’ districts. To the extent that legislators and their staff collect and rely on firms’ financial statement information, we expect that a change in representation as a result of redistricting will result in a significant and observable change in searches for information about new constituent firms. Our evidence supports this prediction. We also find that the timing of searching coincides with legislators’ roll call votes, particularly ahead of more controversial bills and for bills lobbied by sample firms. Finally, we find that new constituent firms respond to increased information demands after a redistricting event by supplying more policy-relevant disclosures and increasing lobbying.

We document an increase in market power for politically active firms during times of heightened policy uncertainty, when their information and influence advantage is greater. The effect is long-lasting and stronger for large politically active firms. We show that relatively large investments during high uncertainty periods serve as a potential mechanism for gains in market power. Industries populated with politically active firms experience lower business dynamism and import penetration, consistent with active firms leveraging investment timing to restrict competition. Results suggest that political activism is a likely contributing factor to the dominance of large firms over the last two decades.

In this study, we examine whether environmental, social, and governance (ESG) funds' investment decisions are sensitive to the existence and extent of firms' voluntary environmental disclosures. We create our measures of voluntary environmental disclosure using bigrams extracted from the Global Reporting Initiative standards. We provide robust evidence that voluntary environmental disclosure in conference calls is associated with greater ESG fund ownership in the subsequent period, incremental to firms' ESG ratings. We also provide evidence that fund managers' reliance on environmental disclosure is concentrated in water, waste, emissions, and compliance disclosures. ESG fund ownership increases with environmental disclosure that is more positive and specific. Our primary finding persists both when we rely on the sustainability report as an alternative proxy for environmental disclosure and when we use fund‐level tests. Overall, our evidence is consistent with ESG funds relying on firms' disclosures when making investing decisions and inconsistent with recent regulatory concerns that ESG fund managers are not following through on their stated investing strategies.
