Momentum Strategies Versus Directional Momentum Strategies: A Comparative Study With Stocks, Zi Ning

Masters Culminating Experiences (1993-2011)

In replicating the study by Akhbari and Gressis (2002) in mutual funds, this paper compares the profitability of traditional momentum strategy with the directional momentum strategies in stock markets. Not only the past quarterly return but also the patterns of monthly returns within a quarter are considered. The evidence shows that the raw return findings are similar to the findings in mutual fund study. However, the risk- adjusted returns are not consistent with the raw returns and statistically insignificant, very probably, due to the extremely small sample size.

You Say You Want A Revolution:Music In Advertising And Pseudo-Counterculture, Alan Bradshaw, Roger Sherlock, Pierre Mcdonagh

Conference papers

Using the example of the song Revolution by the Beatles and its use in a TV ad for Nike, this paper explores the conference theme of the impact of marketing and marketing systems in society from the subtheme of art and aesthetics in markets. We consider the role of music in advertisements as the appropriation and negation of counterculture against Adorno & Horkheimer’s critique of the commodification form of the music itself independent of appropriation. The paper considers these research problematics from the perspective of the musicians themselves.

Public Posting As A Strategy To Increase Walking: A Worksite Intervention, Rayleen Earney, Timothy J. Bungum

Environmental & Global Health Faculty Research

Because most American adults do not meet recommended physical activity guidelines, the need for new and innovative strategies is apparent. The current study employed public posting in an attempt to increase walking behavior in a worksite setting. Pedometer generated data was publicly posted in a prominent location in the worksite. In our study that utilized a pre-experimental design, we found that walking steps were statistically higher during the intervention and in a post intervention period as compared to the baseline data. We conclude that the public posting of physical activity data has the potential to increase walking behavior.

Rapid Calculation Of The Price Of Guaranteed Minimum Death Benefit Ratchet Options Embedded In Annuities, Eric R. Ulm

Journal of Actuarial Practice (1993–2006)

This paper presents a new method of obtaining quick and accurate values and deltas for discrete look back options using Taylor series expansions. This method is applied to the case of ratchet guaranteed minimum death benefits attached to annuity contracts, and the method is extended to include annuities where a fixed fund is attached to the variable account. Finally, both the speed and the accuracy of the method are compared to Monte Carlo simulation and the exact analytic solution. The Taylor expansion method is shown to be faster and, in most cases, more accurate than the alternative methods.

Approximating The Bias And Variance Of Chain Ladder Estimates Under A Compound Poisson Model, Janagan Yogaranpan, Sue Clarke, Shauna Ferris, John Pollard

Journal of Actuarial Practice (1993–2006)

We consider the problem of estimating the outstanding claims produced by a homogeneous general insurance portfolio. The specific model considered in this paper is one where the number of claims in any loss period follows a Poisson distribution, settlement delays follow the same multinomial distribution, and settlements are single lump sums that are independent identically distributed random variables. Simulations using this model reveal that the development ratios and the outstanding claims estimates produced using the chain ladder method are positively biased. We obtain approximate formulas for the biases using Taylor series expansions of the random variables about their means. The …

Decision Tree Analysis Of Terminated Life Insurance Policies, Robert Keng Heong Lian, Yuan Wu, Hian Chye Koh

Journal of Actuarial Practice (1993–2006)

Statistical methods such as regression and survival analysis have traditionally been used to investigate the factors affecting the duration of terminated life insurance policies. This study explores a different approach: it uses a more recently developed data mining technique called decision trees. By sequentially partitioning the data to maximize differences in the dependent variable (duration in this study), the decision trees technique is good at identifying data segments with significant differences in the dependent variable. This identification can be useful when a company is trying to understand the factors driving or associated with the termination of life insurance policies. Decision …

A Comparative Study Of Parametric And Nonparametric Estimators Of Old-Age Mortality In Sweden, Peter Fledelius, Montserrat Guillen, Jens Perch Nielsen, Kitt Skovso Petersen

Journal of Actuarial Practice (1993–2006)

A recent study of Swedish old-age mortality used a modified GompertzMakeham model with a linear hazard for the force of mortality. We propose an alternative model using smooth two-dimensional kernel hazard estimators and introduce a new estimator based on the multiplicative bias correction for the multivariate marker dependent hazard. The multiplicative bias correction appears to have great potential for estimating mortality rates at the highest ages. We also observe that mortality continues to increase at an exponential rate even in old-age.

Phased Retirement For Defined Benefit Plan Participants, Patricia L. Scahill, Jonathan Barry Forman

Journal of Actuarial Practice (1993–2006)

The demographic makeup of the U.S. workforce is changing. The population between ages SS and 64 is projected to increase significantly by 2020, but employment rates for this age group have not been increasing. Employers will likely need to encourage critical employees in this age group to delay retirement. Phased retirement is one tool for delaying retirement, while also not continuing full-time employment, so it can be a compromise for employers and employees. Both Congress and two administrative agencies have begun to consider changes in pension laws and regulations that would be needed to accommodate phased retirement for employers who …

The Actuarial Value Of Life Insurance Backdating, James M. Carson, Krzysztof Ostaszewski

Journal of Actuarial Practice (1993–2006)

Backdating is a common (and legal) practice in the U.S. whereby a life insurance contract bears a policy date that is prior to the actual application date. This practice often results in the opportunity for some insureds to reduce the annual premium paid. Using cash flow projections and U.S. mortality, lapse, and interest rate data, we provide a model of the actuarial value of term life insurance backdating. Results indicate that the benefits to the applicant of backdating a term life insurance policy increase as the applicant age (and hence premium) increases. Increasing mortality, lapse, and interest rates, as well …

Credibility Theory And Geometry, Elias S.W. Shiu, Fuk Yum Sing

Journal of Actuarial Practice (1993–2006)

We present a geometric approach to studying greatest accuracy credibility theory. Our main tool is the concept of orthogonal projections. We show, for example, that to determine the Buhlmann credibility premium is to find the coefficients of the minimum-norm vector in an affine space spanned by certain orthogonal random variables. Our approach is illustrated by deriving various common credibility formulas. Several equivalent forms of the credibility factor Z are derived by means of similar triangles.

Product Innovation In Financial Services: A Survey, Christopher O'Brien

Journal of Actuarial Practice (1993–2006)

This paper considers product innovation in insurance and other financial services, an area where actuaries have an important role. It considers the proposition that there is no unique formula for success and that what works well in one situation may not work well in another. It first examines the sources of ideas for new products and, in particular, the role played by consumers, which is generally regarded as weak. It then looks at how ideas are implemented, with particular importance attributed to cross-functional teams and the formality of the product development process. Then it considers how success is measured (with …

Estimation Of Complete Period Life Tables For Singaporeans, Siu-Hang Li, Wai-Sum Chan

Journal of Actuarial Practice (1993–2006)

Complete period life tables, with death rates for every year of age, are not available in Singapore. This study constructs such tables for Singaporeans from the limited mortality information contained in the abridged life tables provided by the Singapore Department of Statistics. We find that linear interpolation, Whittaker graduation, and the Coale-Kisker method together can generate complete life tables that are smooth and continuous. The validity of the complete life tables generated by our method is further confirmed by (1) comparing the life expectancies calculated from our estimated life tables with those provided by the Singapore Department of Statistics, and …

“Lucy In The Sky With Diamonds”: Airline Liability For Checked-In Jewelry, Eloisa Rodriguez-Dod

Faculty Publications

It is expected that when you arrive at an airport you most likely will have to check in a bag or two. What is not expected, however, is that someone would rummage through your baggage and take your belongings. Unfortunately, this happens frequently. A passenger packs her jewelry in her luggage, checks that luggage in, boards her flight, and never sees that jewelry again. Once she discovers the missing jewelry, her options for recovering the loss are quite limited.

This article examines the history and current state of the law regarding airline liability for passengers’ lost belongings on domestic as …

Writing Reflective Case Studies For The Engineering Management Journal (Emj), Timothy Kotnour, Rafael Landaeta

Engineering Management & Systems Engineering Faculty Publications

This paper's intent is to help authors write reflective case studies for the Engineering Management Journal (EMJ). We offer a process to convert an applied research project with an organization to an EMJ manuscript. Writing a reflective case study is a process of abstracting experiences into approaches, processes, tools, challenges, and "lessons" for a broad audience of engineering managers. This paper serves as a guide for authors to write reflective case studies.

Including Organizational Cultural Parameters In Work Processes, Holly A. H. Handley, Nancy J. Heacox

Engineering Management & Systems Engineering Faculty Publications

Recent work in modeling decision-making work processes has focused on including the national culture of individual decision-makers in order to emphasize the differences in decision criteria between decision-makers of different nationalities. In addition to nationality, a decision-maker is also a member of an organization and brings this organizational culture to his role in the work process, where it may also affect his task performance. In order to represent the organizational impact on the work process, five organizational cultural parameters were identified and included in an algorithm for modeling and simulation of cultural difference in human decision-making. While the five modifiers …

Mutual Fund Tournaments: Evidence From Global And International Funds, Michael R. Melton, Thomas S. Zorn, Richard A. Defusco

Department of Finance: Faculty Publications

For a sample of global and international equity mutual funds, we test the proposition that managers likely to end up as “losers” manipulate fund risk differently from interim winners. In contrast with Brown, Harlow, and Starks (1996) who found robust support for the tournament model, we found no evidence of tournament like behavior for international and global mutual funds. A possible explanation of this behavior is that investors in these funds are primarily seeking diversification and therefore are less sensitive to relative performance.

Organizational Forming In Amodern Times: Reinserting The Dynamic Into The Organizational, Paul Donnelly

Conference papers

While there is an obvious concern that “new organizational forms” are appearing, and despite the topic receiving increased attention, scholars, as yet, have been unable to theorize, grasp or account for these new forms adequately. In continuing to look for the ‘new’ with ‘old’ lenses, we are seeing neither real departure from Weberian conceptualizations other than oppositional approaches still in search of an essential entity, nor much consideration given to the possibility that the paradigmatic approach to form is also part of the problem. In light of this, I posit that thinking within a modernist epistemological framework has served to …

The Lizard King Of Sobe Beverages, Laurence Weinstein, John Bello

New England Journal of Entrepreneurship

John Bello, aka the “Lizard King,” has been lionized in the business press as having been the brilliant entrepreneur who started a beverage company from scratch in early 1995 with his partner, Tom Schwalm, and then sold the product line to PepsiCo seven years later for a reported $375 million. What many people do not know is how close Bello came to failing with his SoBe line of innovative drinks.

Cashing In On Seafood, Laurence Weinstein, Stephen Heard

New England Journal of Entrepreneurship

Stephen Heard graduated from the University of Rhode Island in 1970 with a degree in business administration. He started his career by signing up as a management trainee at Woolworth’s Department Store in Wellesley, Massachusetts. It didn’t take him long to realize he missed his calling: being by the Rhode Island shoreline and employed in the fishing industry. Nearly 35 years later, Stephen is a self-made multimillionaire, having followed both his passion for entrepreneurship and for living his life on the Atlantic coast.

Employee Equity, Incentive Compensation, And Growth In Entrepreneurial Firms, Ben Arbaugh, Larry W. Cox, S. Michael Camp

New England Journal of Entrepreneurship

We examined the relationship between employee equity compensation, incentive compensation, and firm growth using a sample of 480 privately held firms from the Ewing Marion Kauffman Foundation’s database of Ernst & Young Entrepreneur Of The Year (EOY) winners. Using frameworks from agency and motivation theories, we argued that larger percentages of both equity- and incentive-based compensation allocated to top managers and employees would be associated with firm growth. After controlling for firm and industry effects, the results of the study showed that while the firms in the sample preferred providing incentive compensation, providing equity compensation for employees was a positively …

Elements Of Infrastructure: Factors Driving International Entrepreneurship, Stephen K. Callaway

New England Journal of Entrepreneurship

This article focuses on "born globals" (Knight and Cavusgil 1996) and interfirm resources to explain international entrepreneurship. The theory posed here challenges the traditional image of international business as a long, gradual process not occurring until later in the life cycle, and applying only to large multinational corporations (MNCs).

Increasingly, new ventures must expand their operations internationally early in their history in order to be competitive (Oviatt and McDougall 1994), and require infrastructure (Van de Ven 1993), or interfirm resources, for success. Specifically, firms may rely on three factors to expand internationally: cost factors, unique global resources, and networks.

Seeking God (In The Details), Joseph E. Levangie

New England Journal of Entrepreneurship

Entrepreneurs tend to be self-styled “idea” people. They often believe they have the next “Big Concept”—one which could change the world, reaffirm their self-worth, and, of course, make them and their venture team a fortune. In contrast, as they build a company to implement their business dream, entrepreneurs also tend to eschew or trivialize administrative details. Why should they waste their creative juices on minutia? As a result of this insensitivity to detail, these captains of capitalism often trip in their entrepreneurial journey. For example, they might:

• Forget to remit payroll taxes on schedule.

• Fail to document the …
