For thirty-five years, courts and scholars have been divided over the effects of defensive tactics in the market for corporate control. Strong defensive tactics locate authority to accept a hostile bid in the target’s board. The board can bargain for a higher takeover price than uncoordinated shareholders could realize, but high takeover prices may reduce shareholder returns by reducing the likelihood of receiving a bid. The Delaware Courts themselves disagree. The Delaware Chancery Court would locate ultimate decision authority in the tar- get’s shareholders, while the Supreme Court, by permitting strong defensive tac- tics, allocates extensive power to the target’s board. Though the Supreme Court’s view settles the legal issue in Delaware for now, the normative debate among scholars and decision makers regarding whether the shareholders or the board should decide remains unresolved.

Event studies, a half-century-old approach to measuring the effect of events on stock prices, are now ubiquitous in securities fraud litigation. In determining whether the event study demonstrates a price effect, expert witnesses typically base their conclusion on whether the results are statistically significant at the 95% confidence level, a threshold that is drawn from the academic literature. As a positive matter, this represents a disconnect with legal standards of proof. As a normative matter, it may reduce enforcement of fraud claims because litigation event studies typically involve quite low statistical power even for large-scale frauds.

The public benefit corporation (“PBC”) is one of the most hyped developments in corporate law, due to the PBC’s unique social purpose. Unlike the traditional corporation, directors of PBCs are required under their fiduciary duties to con- sider the impact of their decisions on a range of stakeholders and communities. This new form is hailed by many as a framework for a reformed capitalism. Critics, on the other hand, have assailed PBCs as unworkable, at best allowing corporations to “green wash,” or providing a thin disguise for ordinary corporate profit-seeking behavior.

To improve financial regulation, scholars have engaged in extensive research over the past decade to try to understand why systemically important financial firms engage in excessive risk-taking. None of that research fully explains, how- ever, the unusually excessive risk-taking by financial guarantors such as bond insurers, protection sellers under credit-default-swap (CDS) derivatives, credit enhancers in securitization transactions, and even issuers of standby letters of credit. With tens of trillions of dollars of financial guarantees outstanding, the potential for failure is massive. This Article argues that financial guarantor risk- taking is influenced by a previously unrecognized cognitive bias, which it calls “abstraction bias.” Unlike banks and other financial firms that pay out capital—for example, by making a loan—at the outset of a project, financial guarantors do not actually transfer their property at the time they make a guarantee. As a result, they may view their risk-taking more abstractly, causing them to underestimate the risk (even after discounting for the fact that payment on a guarantee is a contingent obligation). The Article provides empirical evidence showing that abstraction bias is real and can influence even sophisticated financial guarantors. The Article also examines how understanding abstraction bias can improve the regulation of financial guarantor risk-taking.
