Analytic option pricing and risk measures under a regime-switching generalized hyperbolic model with an application to equity-linked insurance

Option pricing and managing equity linked insurance (ELI) require the proper modeling of stock return dynamics. Due to the long duration nature of equity-linked insurance products, a stock return model must be able to deal simultaneously with the preceding stylized facts and the impact of market structure changes. In response, this article proposes stock return dynamics that combine Lévy processes in a regime-switching framework. We focus on a non-Gaussian, generalized hyperbolic distribution. We use the most popular linked equity of ELIs, the S&P 500 index, as an example. The empirical study verifies that the proposed regime-switching generalized hyperbolic (RSGH) model gives the best fit to data. In investigating the effects of stock return modeling on pricing and risk management for financial contracts, we derive the characteristic function, embedded option price, and risk measure of equity-linked insurance analytically. More importantly, we demonstrate that the regime-switching generalized hyperbolic (RSGH) model is realistic and can meet the stylistic facts of stock returns, which in turn can be employed in option pricing and risk management decisions.     

Redesigning nurse staffing plans for acute care hospitals

Johnson City Medical Center's approach to maximizing staffing in nursing units, particularly in acute care settings, had four primary goals: Identify opportunities to maximize the effectiveness of nurse staffing based on a review of core staffing schedules. Reduce cost duplication and improve workflow. Decrease the use of contract labor (with the goal of eliminating the use of contract labor). Develop financial dashboards for staffing that could be used by nursing managers.     

Private Equity and Portfolio Companies: Lessons from the Global Financial Crisis

Critics of private equity have warned that the high leverage often used in PE‐backed companies could contribute to the fragility of the financial system during economic crises. The proliferation of poorly structured transactions during booms could increase the vulnerability of the economy to downturns. The alternative hypothesis is that PE, with its operating capabilities, expertise in financial restructuring, and massive capital raised but not invested (“dry powder”), could increase the resilience of PE‐backed companies. In their study of PE‐backed buyouts in the U.K.—which requires and thereby makes accessible more information about private companies than, say, in the U.S.—the authors report finding that, during the 2008 global financial crisis, PE‐backed companies decreased their overall investments significantly less than comparable, non‐PE firms. Moreover, such PE‐backed firms also experienced greater equity and debt inflows, higher asset growth, and increased market share. These effects were especially notable among smaller, riskier PE‐backed firms with less access to capital, and also for those firms backed by PE firms with more dry powder at the crisis onset. In a survey of the partners and staff of some 750 PE firms, the authors also present compelling evidence that PEs firms play active financial and operating roles in preserving or restoring the profitability and value of their portfolio companies.     

New development: Complexity and rhetoric in social impact investment

ABSTRACT

Existing public policy approaches to the social impact investment market take a linear view of both social innovation and economic markets. This article analyses the rhetoric of the market to explain both the persistence of a linear view and its inadequacy for dealing with the complexity of bridging social and financial goals. It then outlines complexity-sensitive theories of social innovation and economic markets and their import for social impact investing.     

Revisiting U.S. country of origin labeling trade damage estimates how does an equilibrium displacement model perform under different scenarios

Mexico and Canada successfully challenged the U.S. mandatory country of origin labeling (COOL) requirements for beef and pork as inconsistent with World Trade Organization (WTO) rules, which ultimately led to arbitration over the level of trade lost due to the COOL measure. During this phase of the dispute, Mexico, Canada, and the United States provided the Arbitration Panel with estimates of the trade losses caused by COOL that were produced using different quantitative methods. The U.S. estimates were based on an equilibrium displacement model (EDM). This article presents a version of the EDM used by the U.S. Government to calculate trade losses due to COOL. The Panel developed its own analysis combining econometric analysis and an EDM that used only supply-side information to calculate changes in Canadian and Mexican livestock trade. The U.S. EDM includes both the supply and demand sides of the market. We use the U.S. EDM and the Panel's assumptions to re-estimate the value of lost trade due to COOL. The inclusion of demand-side effects and domestic COOL costs produces lower estimated trade damages than those produced using the Panel's analysis, validating the EDM as a useful quantitative tool for this type of trade policy analysis.     

Compensation of Economists—Measuring the Market Value of NABE Member Characteristics

This study is based on the 2008 NABE salary survey and provides detail on the estimated relationship between the total compensation and the professional characteristics of NABE members who responded to the survey. This study builds on previous work done by Peter Jaquette in analyzing the 2006 salary survey data. We find many similarities to the 2006 results, but also find interesting exceptions in the 2008 sample that suggest further inquiry in subsequent survey analysis.     

Research Ethics of Business Academic Researchers at AACSB Institutions

Academic researchers in business are likely to have different perceptions and attitudes regarding what constitute unethical behavior in conducting their research. In fact, some might consider certain actions to be totally ethical while other behaviors might be unacceptable in one discipline, but acceptable in another. Therefore, a survey was administered to a sample of professors at AACSB-accredited institutions to identify those actions felt to be unethical and to gauge the state of research ethics among business academics. The survey was developed around eleven substantive issues concerning business research ethics. Some of the topics included: treatment of data, confidentiality, plagiarism, working with co-authors, and multiple submissions. First, respondents were asked whether they felt the behavior was unethical. Secondly, they were asked whether they had ever personally engaged in such activity. Finally, they were asked if they were aware of colleagues who had taken a particular action.The primary contribution of the paper is to provide evidence on faculty definitions of unethical research practices and the extent of such behavior within the academic business environment. An overwhelming percentage of respondents (greater than 95%) condemned five of the eleven activities studied. They included: falsifying data, violating confidentiality of a client, ignoring contrary data, plagiarism, and failing to give credit to co-authors. Probably the most important finding of this paper concerns the level of unethical activity reported by faculty about their colleagues. While these findings likely include some degree of double counting within an institution, the level of unethical activity reported on colleagues and the number of institutions represented indicates the problem is quite common. Seven actions were reported by between 20 and 47% of respondents to have occurred within their institutions. These actions include adding names of persons not contributing to a paper, failing to give credit to co-authors, selective reporting of data, and plagiarism. These results indicate unethical practices occur frequently among researchers in AACSB accredited business schools and are not merely exceptions. Coverage of ethical issues in a graduate research methods course might force students to ponder these issues prior to confronting them in the world of business or academic research.     

Moral Reasoning "On Hold" During a Competitive Game

When a person engages in a "game," that person may reason and behave in a manner that is inconsistent with non-game-situation moral reasoning. In this study we measured moral reasoning with the Defining Issues Test (DIT). We then engaged the students in a competitive game and collected accounts of their "reasoning" by having them explain their decisions with a forced choice inventory. The results indicate that there were significant inconsistencies in moral reasoning between non-game and game situations. The implications of this for business ethics are discussed.     

Generalized purchasing power parity and the case of the European Union as a successful currency area

This article uses multicountry purchasing power parity (PPP) tests to study the success of the European monetary system (EMS) in creating a successful currency area for a stable European monetary union. If the EMS has sufficiently integrated the fundamentals within the European Union, then real exchange rates between member countries will share a common stationary trend when denominated by a common outside currency. Previous research using two-country PPP tests have been inadequate in explaining the nonstationary nature of real exchange rates between the EMS countries and nonmember countries. The use of generalized PPP tests can show that even though individual exchange rates within the EMS may appear to be nonstationary with respect to outside countries, some of them will combine to form a currency union with a stable stationary trend.
