This paper examines the anticipated components of bidder returns by focusing on the banking industry around the passage of interstate deregulation (Riegle Neal Act of 1994). Overall, firms that became bidders after Riegle Neal have large significant positive returns during its passage. Moreover, these positive wealth effects are significantly larger than the effects at the merger announcement. These results suggest that bidder returns are anticipated and focusing only on narrow event windows underestimates gains to bidders. Finally, the positive bidder returns appear to provide evidence against both the entrenchment and hubris hypotheses. Additional tests provide evidence to suggest that mergers are motivated by synergy rather than disciplinary motives.

This paper examines the financing decisions of firms in response to changes in investments and profits. We find that information frictions play important roles in firms' financing decisions. However, we find no evidence that asymmetric information about the value of a firm's assets causes equity to be used only as a last resort. Indeed equity is the predominant source of finance in situations, such as profit shortfalls, investment in intangible assets, and internally generated growth opportunities, where informational asymmetries and agency costs are likely to be high. We also find that firms respond asymmetrically to positive and negative profit shocks. In financing fixed assets, high asymmetric information firms use more short-term debt and less long-term debt, whereas firms with high potential agency problems use significantly more equity and less long-term debt and cash.

We test the signaling and wealth transfer hypotheses around the announcement of share repurchases using a recent and larger sample of data than previously examined while employing a methodology designed to enhance the power of our tests. Disentangling the wealth transfer and signaling hypotheses is difficult; they are not mutually exclusive and can have opposite effects for bondholders. Wealth transfers decrease bondholder wealth while positive signals increase it; the combined result obscures tests of each hypothesis. By focusing on sub-samples where signaling is more and less likely to be present we increase our ability to isolate the separate effects. In addition to traditional tests of wealth effects, we feature information inherent in the correlation of wealth changes to equity and debt. Our results are generally consistent with the positive signaling effect of stock repurchases, but also provide some support for wealth transfer. Our work also emphasizes the importance of trying to disentangle the various hypotheses. In the subset of option funding repurchases, where signaling effects are less likely, the positive correlation of wealth changes between stockholders and bondholders is completely eliminated. Bond ratings are much more likely to be upgraded in samples without executive options which is precisely where the signaling effects are expected to be concentrated. Firms with weaker shareholder rights experience greater bondholder wealth losses at the announcement of stock repurchases.
