1) "Entrenched Management, Stakeholders, and Capital Structure: Project Summary" with David Frankel of the Melbourne Business School at the University of Melbourne.
Abstract: We study the e§ects of combining managerial entrenchment (Harris and Raviv 1990) with liquidation-averse stakeholders (Titman 1984). When a firm's debt is below (above) its liquidation value, small debt increases have a high (low) marginal cost for the stakeholders: if they lead to insolvency, then the firm must be worth less (more) as a going concern than as the sum of its assets - so it will (not) be liquidated. Because of this declining marginal cost of debt, a firm's value is a nonconcave function of its debt level and thus has multiple local maxima. Consequently, small shocks can cause large jumps in a firm's optimal debt level even in the absence of issuance costs. The model also has many implications for a firm's optimal leverage, liquidation risk, and market value, as well as the welfare of its small stakeholders.
