This paper examines the wealth impact of share repurchases that restrict participation to a particular sub-set of a firm's stockholders. Repurchases at a premium from insiders and small shareholders increase the wealth of non-participating stockholders and are therefore consistent with the shareholders' interest hypothesis. However, privately negotiated repurchases of single blocks from stockholders unaffiliated with the firm reduce the wealth of non-participating stockholders. In contrast to the evidence for general repurchases, no positive wealth effect offsets the significant repurchase premium paid to the selling stockholder. Indeed, the wealth loss to non-participating stockholders is significantly greater than the premium paid. This evidence is inconsistent with the shareholders' interest hypothesis and supports the hypothesis that managers in their self-interest use single block repurchases to eliminate threats to their control over the firm's resources.

This paper documents that a successful tender offer increases the combined value of the target and acquiring firms by an average of 7.4%. We also provide a theoretical analysis of the process of competition for control of the target and empirical evidence that competition among bidding firms increases the returns to targets and decreases the returns to acquirers, that the supply of target shares is positively sloped, and that changes in the legal/institutional environment of tender offers have had no impact on the total (percentage) synergistic gains created but have significantly affected their division between the stockholders of the target and acquiring firms.

This paper investigates the rationale behind interfirm tender offers by examining the returns realized by the stockholders of firms that were the targets of unsuccessful tender offers and firms that have made unsuccessful offers. Our results suggest that the permanent positive revaluation of the unsuccessful target shares [documented by Dodd and Ruback (1977) and Bradley (1980)] is due primarily to the emergence of and/or the anticipation of another bid that would ultimately result in the transfer of control of the target resources. We also find that the rejection of a tender offer has differential effects on the share prices of the unsuccessful bidding firms depending upon whether the tender offer process results in a change in the control of target resources. On the basis of these results we conclude that acquisitions via tender offers are attempts by bidding firms to exploit potential synergies, not simply superior information regarding the ‘true’ value of the target resources.

This paper documents frequent attempts by activist arbitrageurs to open-end discounted closed-end funds, particularly after the 1992 proxy reform which reduced the costs of communication among shareholders. Open-ending attempts have a substantial effect on discounts, reducing them, on average, to half of their original level. The size of the discount is a major determinant of whether a fund gets attacked. Other important factors include the costs of communication among shareholders and the governance structure of the targeted fund. Our study contributes to the understanding of the actions undertaken by arbitrageurs in financial markets beyond just pure trading.
