Convertible Bond Arbitrage: Risk and Return

Abstract:  This paper specifies a simulated convertible bond arbitrage portfolio to characterise the risks in convertible bond arbitrage. For comparison the risk profile of convertible bond arbitrage hedge fund indices at both monthly and daily frequencies is also examined. Results indicate that convertible bond arbitrage is positively related to default and term structure risk factors. These risk factors are augmented with the simulated convertible bond arbitrage portfolio, mimicking a passive investment in convertible bond arbitrage, to assess the risk and return of individual hedge funds. We provide estimates of the performance of two hedge fund indices (an equally weighted and value weighted index) and a sample of convertible bond arbitrage hedge funds using a factor model methodology. Lagged and contemporaneous observations of the risk factors are specified, controlling for illiquidity in the securities held by funds. Our results cover two time periods. Initially we find evidence of abnormal risk adjusted returns in the individual hedge fund data and the equally weighted hedge fund index and no evidence of abnormal risk adjusted returns in the value weighted hedge fund index. When we examine performance during the credit crisis of 2007 and 2008 we find evidence of negative abnormal returns amongst individual hedge funds and the hedge fund indices.     

Therapy,Enhancement, and Medicine: Challenges for the Doctor–Patient Relationship and Patient Safety

There are ethical guidelines that form the foundation of the traditional doctor–patient relationship in medicine. Health care providers are under special obligations to their patients. These include obligations to disclose information, to propose alternative treatments that allow patients to make decisions based on their own values, and to have special concern for patients’ best interests. Furthermore, patients know that these obligations exist and so come to their physicians with a significant level of trust. In this sense, therapeutic medicine significantly differs from straightforward business practices such as the buying and selling of houses, cars, cell phones, etc. However, we argue that this relationship differs when medicine is used for enhancement rather than therapy. When patients seek enhancements they are not as vulnerable as when they are ill. And in an enhancement setting, physicians have little role outside of medical risks to discuss motivation and alternatives. Therefore, we conclude that a more reasonable alternative may be for doctors and patients to use ethical norms associated more with straightforward business practices, specifically sales. We believe that full disclosure of this different set of norms will benefit both physicians and patients.     

LINKING CHANGES IN REVEALED CAUSAL MAPS AND ENVIRONMENTAL CHANGE: AN EMPIRICAL STUDY

This article explores the cognitive maps of the dominant coalition of one firm over time. It begins with an overview of the cognitive mapping literature and discusses ‘revealed cognitive maps’ as one strategy for measuring managerial cognitive structures. Next, the revealed cognitive maps from one company over a 20-year period are analysed for their fit with the company's environmental context. The data suggest that the fit between cognitive structures and the environment was less than perfect, and that decision-makers both under-identified and over-identified certain environmental factors. These and other data are discussed within the context of a cognitive approach to managerial thinking.     

Information Technology, US Union Organizing and Union Effectiveness

This paper examines the effects of information technology (IT) on organizing and union effectiveness in US national unions. Original survey data and data from government and independent sources are combined to model outcomes including membership growth, success in representation elections, and union leaders' assessments of effectiveness as a product of environmental and organizational characteristics. The results suggest that the practical impact of IT use on organizing outcomes can be quite important. Evidence regarding the impact of IT on overall effectiveness (i.e. organizational or union effectiveness) is more mixed.

“PAY IT FORWARD” AND HIGHER EDUCATION SUBSIDIES: A MEDIAN VOTER MODEL

Since 2012, at least 24 states have considered legislation on Pay It Forward (PIF) models of higher education finance (which enable students to pay the price of college upon departure from an institution, as opposed to paying upfront tuition). This paper proposes a theoretical model of PIF policies within a framework in which voters belonging to different income groups vote over the level of subsidies to higher education. We analyze the impact of two types of potential PIF policies—a deferred tuition approach and an income share approach—on college access and on voting equilibria over subsidy levels. The results show that college access is enhanced by PIF policies. The equilibrium level of subsidies depends crucially on the pattern of income distribution, in particular on the relationship between mean income and the income of the median income group, and on whether higher education widens or narrows the distribution of income. We show that the equilibrium level of subsidies to higher education will not necessarily decline under PIF, and may increase in some circumstances due to changes in college access for low‐income groups.
