Partisan regulatory actions: Evidence from the SEC

Abstract

We study the influence of political partisanship in SEC investigations and AAER enforcement actions against financial misconduct. We find that the SEC is more likely to launch an investigation against a firm that is misaligned with the agency’s political ideology than other firms. The likelihood of an AAER appears unaffected by political misalignment, but once named in an AAER, a misaligned firm faces harsher penalties than other firms. We find evidence that collectively points to potential misallocation of scarce enforcement resources due to partisanship: conditional on investigation, misaligned firms are less likely to receive an enforcement action, and conditional on misreporting, non-misaligned firms are less likely to be investigated.
