Knowledge that Transforms

Proponents of state antitakeover legislation argue that previous empirical tests by financial economists of the wealth effects of Pennsylvania's 1990 antitakeover law are biased. We show that the proponents are correct. In particular, firm size, event-time clustering, and non-synchronous trading effects account for the wealth decreases reported in earlier studies. We also show, however, that both proponents and critics of the Pennsylvania legislation have ignored the earliest press release about it. The wealth effect associated with this announcement is negative, large, and statistically significant. These results therefore are consistent with the hypothesis that the Pennsylvania law decreased company values and with the hypothesis that the initial market reaction is an unbiased estimate of the law's effect on firm values.

This paper seeks to provide an explanation for why corporate officers manage the disclosure of accounting information. We show that earnings management affects firm value when value-maximizing managers and investors are asymmetrically informed. In equilibrium, the strategic management of reported earnings influences investors' assessments of the market values of companies' shares.

Previous work suggests that, when the debtor has private information on the future profitability of the firm, financial distress is costly even if debt can be renegotiated. This paper shows that adverse selection problems can be completely avoided by offering creditors a mix of cash and equity in the renegotiation. Empirical evidence indicates that this is common practice in corporate debt workouts. However, asymmetric information leads to inefficiencies if equity is not treated as the residual claim in bankruptcy. In this case, equilibria exist in which distressed firms go to court too often.

We estimate continuous-time event-history models of the acquisition of conglomerate vs. non-conglomerate and predatory vs. friendly acquisitions among the 1962 Fortune 500 between January, 1963, and December, 1968. Our analysis of predatory acquisitions reveals that there were strong disciplinary motivations for these acquisitions in the 1960s. Q ratios were, by a large margin, the most important determinant of predatory acquisition likelihood. Surprisingly, however, corporate boards appear to have provided little alternative to predatory acquisition as a monitoring mechanism during this period. Friendly acquisitions, on the other hand, were concentrated among firms with low price-earnings ratios and high return on equity, suggestive of the earnings manipulation story often associated with conglomerate acquisitions. Our analysis of conglomerate acquisitions reveals that there were strong disciplinary motivations for conglomerate acquisitions during this period. Conglomerate targets had low Q ratios and were as likely as non-conglomerate targets to be acquired in a predatory fashion. We find no evidence that conglomerate acquisitions were motivated by a desire to improve earnings-per-share numbers, as some have maintained. In addition, regardless of type or tenor, we find managerial ownership, firm size, and industrial organization motivations for acquisition are consistently important determinants of acquisition likelihood.
