Abstract We analyze shareholder activism by “quasi-insiders”: founders, former executives, and other individuals tangentially connected to a firm. These individuals seek control in their campaigns, use aggressive tactics, and target smaller, poorly performing firms. Their campaigns are associated with positive announcement returns. Former CEOs who engage in campaigns often depart from the target under negative circumstances before launching their campaigns soon afterward. Our results suggest that insiders at the periphery of control may intervene in firms too small for traditional activists to target. (JEL: G34, G32)

Abstract We consider a model in which a security issuer can manipulate information observed by a credit rating agency (CRA). We show that stricter screening by the CRA can sometimes lead to increased manipulation by the issuer. Accounting for the issuer’s behavior pulls optimal CRA screening toward the extremes of laxness or stringency. Surprisingly, an improvement in prior asset quality can result in more rating errors. In a two-period version of the model, stricter screening can result in more short-run rating errors. Our results suggest complex interplay between issuer and CRA behavior, complicating the evaluation of CRA policy effectiveness.
