Educational Insights: A Hybrid Course in Risk Management and Insurance

Universities and colleges continue to face constraints related to classroom space and faculty time, thus increasing the need to consider options such as hybrid courses that can leverage available resources. This article discusses the benefits of a hybrid course, as well as its design and implementation at a large, public university. In addition, for universities that use the introduction to risk and insurance course as a significant course for attracting majors, we identify the benefits for students from the use of hybrid courses, such as the variety of materials and activities utilized, as well as the flexibility in scheduling. This information may be useful in marketing the course so that it will be immediately attractive to students.     

Smoothing Mechanisms in Defined Benefit Pension Accounting Standards: A Simulation Study*

The accounting for defined benefit (DB) pension plans is complex and varies significantly across jurisdictions despite recent international convergence efforts. Pension costs are significant, and many worry that unfavorable accounting treatment could lead companies to terminate DB plans, a result that would have important social implications. A key difference in accounting standards relates to whether and how the effects of fluctuations in market and demographic variables on reported pension cost are “smoothed". Critics argue that smoothing mechanisms lead to incomprehensible accounting information and induce managers to make dysfunctional decisions. Furthermore, the effectiveness of these mechanisms may vary. We use simulated data to test the volatility, representational faithfulness, and predictive ability of pension accounting numbers under Canadian, British, and international standards (IFRS). We find that smoothed pension expense is less volatile, more predictive of future expense, and more closely associated with contemporaneous funding than is “unsmoothed” pension expense. The corridor method and market‐related value approaches allowed under Canadian GAAP have virtually no smoothing effect incremental to the amortization of actuarial gains and losses. The pension accrual or deferred asset is highly correlated with the pension plan deficit/surplus. Our findings complement existing, primarily archival, pension accounting research and could provide guidance to standard‐setters.     

Dynamics of the Market for Medical Malpractice Insurance

Public attention has been directed recently at the market for medical malpractice insurance, yet disagreement persists over whether this market has changed and, if so, what has caused this change. In this study, we examine factors that affect the market for this insurance, including the growth in premiums, losses, and investment earnings, and loss variability. Our analysis suggests that there was significant deterioration in the market for medical malpractice insurance beginning in 1998 and culminating in 2001. We conclude that insurers' losses are the primary driver of the market deterioration during the period 1998 through 2003.     

Race and the development of career interest in accounting

Data from the AICPA (2009b) show that African–Americans comprise only 1% of CPAs and were only 4% of new hires by CPA firms in academic year 2007–2008. The current study uses social cognitive career theory to examine whether this shortage of diversity may be caused by differences between African–American and Caucasian students in factors that lead to career interest in accounting. Students were surveyed on two key personal variables: self-efficacy and outcome expectations. Results suggest that African–American students are more likely than Caucasian students to perceive accounting as providing outcomes that match their values. However, favorable perceptions may be countered by differences in self-efficacy. African–American students value outcomes provided by accounting, but they may have less confidence, compared to Caucasian students, that they can successfully complete the course of action necessary to enter the profession.     

Post‐merger strategy and performance: evidence from the US and European banking industries

The banking industry has one of the most active markets for mergers and acquisitions. However, little is known about the type of operational strategies adopted by banking firms in the years following a deal. For a sample of bidding banks in the USA and Europe, this study compares the design and performance implications of different post‐merger strategies in both geographical regions. Using accounting data, we show that European banks pursue a cost‐cutting strategy by increasing efficiency levels vis‐à‐vis non‐merging banks and by cutting back on both labour costs and lending activities. US banks, on the other hand, raise both interest and non‐interest income in the post‐merger period.     

Is integration I(d) applicable to observed economics and finance time series?

The method of cointegration in regression analysis is based on an assumption of stationary increments. Stationary increments with fixed time lag are called ‘integration I(d)’. A class of regression models where cointegration works was identified by Granger and yields the ergodic behavior required for equilibrium expectations in standard economics. Detrended finance market returns are martingales, and martingales do not satisfy regression equations. We ask if there exist detrended processes beyond standard regression models that satisfy integration I(d). We show that stationary increment martingales are confined to the Wiener process, and observe that martingales describing finance data admit neither the integration I(d) nor the ergodicity required for long time equilibrium relationships. In particular, the martingales derived from finance data do not admit the time (or ‘space’) translational invariance required for increment stationarity. Our analysis explains the lack of equilibrium observed earlier between FX rates and relative price levels.     

Do German security analysts herd?

We employ an innovative methodology suggested by Bernhardt et al. (J. Financ. Econ. 80:657–675, 2006) to examine the herding (or anti-herding) behavior of German analysts regarding earnings forecasts. This methodology avoids well-known shortcomings often encountered in related studies, such as correlated information signals, unexpected common shocks to earnings, systematic optimism or pessimism, or forecast target mismeasurement. Our findings suggest that German analysts anti-herd, that is, they systematically issue earnings forecasts that are further away from the consensus forecast than their private information indicates. Furthermore, we analyze the association between herding behavior and different characteristics, including the size of the brokerage, general or firm-specific experience, and the coverage of firms on the Neuer Markt. We mainly confirm findings for the United States, for example, that anti-herding is more severe in cases of higher competition among analysts. Contrary to anecdotal evidence, we also find anti-herding behavior in earnings forecasts for Neuer Markt firms during the “new economy” bubble.

An Acceptable Consistency-Based Framework for Group Decision Making with Intuitionistic Preference Relations

This article studies acceptable consistency of intuitionistic preference relations (IPRs) and examines how to aggregate individual IPRs into a collective judgment in a group decision making (GDM) context. A consistency index is first introduced to measure the consistency level, thereby defining acceptable consistency for IPRs. If a decision-maker is unwilling or unavailable to revise his/her judgment for an IPR with unacceptable consistency, an automated approach is developed to improve its consistency to an acceptable level. The acceptably consistent IPRs are subsequently aggregated into a group opinion by using an induced ordered weighted averaging operator. A procedure is then proposed to solve GDM problems with IPRs. An illustrative example is presented to demonstrate the effectiveness and applicability of the proposed approach.     

The evolution of longevity: Evidence from Canada

Canadian men in the top earnings ventile live eight years (11%) longer than do men in the bottom ventile. For women, the difference is 3.6 years. This earnings–longevity gradient has shifted uniformly across earnings groups through time, in stark contrast to in the US. We demonstrate that the widely used period measurement method can differ from cohort measures. For middle‐aged men, we find a recent slowdown of mortality improvements, echoing the situation in the US. With comparable data, the Canadian earnings–longevity gradient is half the US gradient; but one quarter of this gap may result from Canada–US earnings differences.     

Implementing Lean Sigma in pharmaceutical research and development: a review by practitioners

The authors recount their experience of the implementation of lean thinking and Six Sigma in pharmaceutical development research and development (R&D). Use of Lean Sigma in pharmaceutical manufacturing is widespread and generally noncontentious. Lean Sigma is used successfully to improve the development of new pharmaceutical manufacturing processes. However, the value of the application of lean and Six Sigma ideas to research & development is controversial. Published material is reviewed, and then the methods, tools, barriers and benefits are discussed, with recommendations for implementation of Lean Sigma into an R&D organisation.
