Three Essays On Hedge Funds, Liping Qiu

Doctoral Dissertations

In Essay 1, we find that, on average, hedge funds decrease leverage prior to the beginning of the financial crisis, with leverage remaining below the pre-crisis levels. We also find that younger funds with lower current leverage and stricter fund governance are more likely to increase leverage following favorable performance; funds exposed to higher risk, higher management fee and higher current leverage tend to delever. Managers increase leverage in order to enhance future performance following superior returns only to be disappointed. We find mixed evidence on the performance difference between levered and unlevered funds, but levered funds do survive longer. …

The Roles Boards Play In Ceo Succession Planning, Yi Li Rivolta

Doctoral Dissertations

A lack of CEO succession planning increases business risk as disruption is more likely during a CEO transition. One difficulty of examining the importance of CEO succession planning is that the planning process is difficult to observe and evaluate. The main purposes of this dissertation are two-fold. First is to investigate whether CEO succession planning matters by comparing disruption costs in firms with planned departure and those with unexpected CEO departures due to death and illness. The second purpose is to investigate whether inside or outside directors improve organizational resiliency using the context of sudden CEO departures when CEO succession …

The Importance Of Executive Effort, Lee Edward Biggerstaff

Doctoral Dissertations

Agency theory stipulates that managerial effort is important to shareholders and costly for managers to provide. Executives may provide sub-optimal levels of effort because shareholders cannot easily observe the day-to-day actions of managers and therefore have difficulties properly monitoring the effort provided by firm management. Researchers also face the challenge of measuring executive effort. In this dissertation, I use an observable measure of leisure consumption to proxy for the effort provided by executives to study the impact of executive effort on firm outcomes.

In the first essay, I focus on Chief Executive Officers (“CEOs”) and the impact of their effort …

Indefinite Knapsack Separable Quadratic Programming: Methods And Applications, Jaehwan Jeong

Doctoral Dissertations

Quadratic programming (QP) has received significant consideration due to an extensive list of applications. Although polynomial time algorithms for the convex case have been developed, the solution of large scale QPs is challenging due to the computer memory and speed limitations. Moreover, if the QP is nonconvex or includes integer variables, the problem is NP-hard. Therefore, no known algorithm can solve such QPs efficiently. Alternatively, row-aggregation and diagonalization techniques have been developed to solve QP by a sub-problem, knapsack separable QP (KSQP), which has a separable objective function and is constrained by a single knapsack linear constraint and box constraints. …

Two Essays On Insider Trading And Option Grants Around The Filing Of Influential Patents, Liu Pan

Doctoral Dissertations

Research documents that insiders, who have access to private information, appear to trade with profits before major corporate events like mergers, bankruptcy, dividend announcements, and future cash flow news (see, e.g., Seyhun, 1990; Seyhun and Bradley, 1997; John and Lang, 1991; Jiang and Zaman, 2010). Another recent stream of studies find that the size and quality of a firm's patent portfolio are positively related to the firm's future stock returns (Hirshleifer, Hsu, and Li, 2012; Pandit, Wasley, and Zach, 2011). However, there is little systematic evidence on whether insiders act opportunistically when they possess private information about the firm's patent …
