Regulators have long disagreed whether regulation would reduce hedge funds’ financial misreporting. On the one hand, critics have stated that hedge funds are unlikely to misreport because their investors are highly sophisticated financial players who can detect and deter financial misconduct. On the other hand, recent changes in the composition of hedge funds’ investors have led many to question this argument.
This dissertation aims to investigate the asset pricing implications of the stock option's implied volatility term structure. We mainly focus on two directions: the volatility term structure of the market and the volatility term structure of individual stocks. The market volatility term structure, which is calculated from prices of index options with different expirations, reflects the market's expectation of future volatility of different horizons. So the market volatility term structure incorporates information that is not captured by the market volatility itself.
This dissertation centers on the role of adverse shocks to household balance sheets in understanding consumer default behavior. The first chapter studies the role of foreclosure contagion: the role of proximate foreclosures in causally triggering other nearby residential defaults and foreclosures. I find that foreclosure activity causally increases nearby rates of consumer defaults.
The service industry has become increasingly competitive. This dissertation addresses a number of outstanding and fundamental questions of competitions in service operations and supply chains. The challenges are characterization of the equilibrium behaviors, estimating the impact of firms' interactions, and designing of efficient market mechanisms.
Some commentators attribute the success of certain hedge fund activism events to “wolf pack” activism, the support offered by other investors, many of whom are thought to accumulate stakes in the target firms before the activists’ campaigns are publicly disclosed. This paper investigates wolf-pack activism by considering the following questions: Is there any evidence of wolf-pack formation? Is the wolf pack formed intentionally (by the lead activist) or does it result from independent activity by other investors?
This dissertation focuses the corporate behaviors in a dynamic world with uncertainty. Especially, I am interested in how firms tradeoff their investment and cash savings when external financing is costly. The first two chapters fit into this theme. One considers optimal investment and financing policies when uncertainty itself is time-varying, the second investigates how firms prepare themselves against devaluation risks. Both chapters build dynamic corporate theories and test them empirically.
Supply chain management is one of the fundamental topics in the field of operations research, and a vast literature exists on the subject. Many recent developments in the field are rapidly narrowing the gap between the systems handled in the literature and the real-life problems companies need to solve on a day-to-day basis. However, there are certain features often observed in real-world systems that elude even these most recent developments. In this thesis, we consider a number of these features, and propose some new heuristics together with methodologies to evaluate their performance.
The following Chapters present an account and evidence that development direction, a previously unexplored characteristic of performance feedback, reveals asymmetries in the transmission and acceptance of feedback. In short, I argue that feedback advising development in the direction of a decrease (e.g., “be less assertive,” “stop overanalyzing decisions”) is less likely to be transmitted by feedback providers, and less likely to be acted upon by feedback recipients, than feedback advising development in the direction of an increase (e.g., “be more assertive,” “analyze decisions more”).
Many systems in services, manufacturing, and technology, feature users or customers sharing a limited number of resources, and which suffer some form of congestion when the number of users exceeds the number of resources. In such settings, queueing models are a common tool for describing the dynamics of the system and quantifying the congestion that results from the aggregated effects of individuals joining and leaving the system.
This paper studies the impact of financial reporting scrutiny on (private) debt contracting in the presence of two capital market frictions: a cash-diversion problem and an asset-substitution problem. When cash flow realizations are not verifiable, firms have an incentive to divert cash by manipulating their accounting reports. When firms' project choices are not verifiable, post financing, they may have an incentive to choose riskier projects than desired by their financiers.
