We study whether the sealing of a defendant's judicial records during a patent lawsuit filing correlates with the defendant's level of competition and disclosure. Courts permit sealing of judicial records when competitive damage outweighs the public interest in access to documents and records....

We study the market reaction to events leading up to and including the release of the SEC’s Proposed Mandatory Climate Risk Disclosures in firms’ financial statements. Our goal is to evaluate whether investors benefit from this proposal. We find the market, on average, does not react to...
