Essays on corporate finance and governance

Abstract: This dissertation contains four essays on various topics in the fields of corporate finance and corporate governance.The first essay, entitled Corporate Governance and Ownership, presents an overview of the causes and consequences of, and possible remedies for, the separation of ownership and control in corporations. In particular, the essay addresses the costs and benefits of ownership concentration. A specific purpose is to put the role of ownership into perspective, while bringing the reader up to date with some recent developments.Essay number two, Shareholder Gains from Equity Private Placements: Evidence from the Stockholm Stock Exchange, contains an empirical investigation of the stockmarket’s reaction to announcements of equity private placements and rights issues. The essay sets out to test a range of hypotheses put forward in the literature. Extensive cross-sectional analyses of private placement discounts and abnormal returns are performed.The third essay is named Optimal Deterrence and Inducement of Take-overs: An analysis of Poison Pills and Dilution. This essay models how the ex ante wealth of shareholders could be increased with customized contractual provisions that affect takeover probabilities and premia. The proposed provisions resemble anti-takeover defense measures in the form of poison pill plans, and conversely, voluntary dilution schemes in the fashion prescribed by Sanford Grossman and Oliver Hart (1980).Finally, the fourth essay models the wealth effects of a particular takeover regulation, The Mandatory Bid Rule. This rule requires a potential bidder for a control position in a target firm to extend the offer to include any or all of the outstanding shares. Although the mandatory bid rule is aimed at the protection of minority shareholders, the essay argues that this regultion is not generally in the best interest of the shareholders.Each essay is self-contained and could, in principle, be read in any order chosen by the reader. However, for readers less familiar with the corporate finance literature, the first essay may also serve as a helpful introduction to the following three essays.
