Measuring Roi: Is It Worth It? Interview By Richard K Thomas, David Marlowe, Daniel Fell, Sheb L. True, Chuck Mcleester

Faculty and Research Publications

Return on investment (ROI) for healthcare marketing is a hot topic among healthcare professionals. It has been discussed off and on in the past, but recent financial developments in healthcare have brought it to the forefront. Today, because of financial pressures, all operational efforts (including marketing) are under intense scrutiny, making the bottom line more important than ever.

Appearances Are Important: Outsourced Internal Audit Services And The Perception Of Auditor Independence, Marshall A. Geiger, D. Jordan Lowe, Kurt J. Pany

Accounting Faculty Publications

The appearance of independence is an important facet of the regulation of auditor independence. The authors conducted a research study to gauge how some financial statement users—loan officers—view and make decisions based on loan proposals that present various types of relationships between the applicant, the auditor that performs the external audit, and the auditor that performs the internal audit function (whether performed in-house or outsourced to the hypothetical loan applicant's external auditor).

The results are insightful: The closer the relationship between the external auditor and the audit client, the higher the perception of inappropriateness, and the less likely the loan …

Closed-End Funds And Turnover Restrictions, Nusret Cakici, Anthony Tessitore, Nilufer Usmen

Department of Accounting and Finance Faculty Scholarship and Creative Works

Past studies have found that investors can earn higher returns than a benchmark by purchasing shares of closed-end funds with discounts or selling shares with premiums. These studies either ignored the impact of transaction costs or used equally weighted portfolio strategies without controls on turnover or transaction costs. We examined whether constraining the holdings of individual funds and turnover has any bearing on the excess returns earned by closed-end equity funds over a benchmark return. We found that when transaction costs were low, portfolios with frequent rebalancing and loose turnover constraints outperformed the benchmark and other portfolios in the period …

Sampling Concepts, Paul Boyd, Ph.D.

MBA Faculty Conference Papers & Journal Articles

The usefulness of any research is dependent upon how well the group studied represents the group about which decisions are to be made or conclusions drawn. That is, it depends upon how well the sample reflects relevant characteristics of the population. When it is possible to study every member of that group there is no problem, for on these occasions we can easily calculate the exact attribute (parameter) of interest for our population.

For example, if we were interested in determining the average number of gallons of gasoline sold to customers at our service station yesterday, we …

Dynamic Funding And Investment Strategy For Defined Benefit Pension Schemes: A Model Incorporating Asset-Liability Matching Criteria, Shih-Chieh Chang, Cheng-Hsien Tsai, Chia-Jung Tien, Chang-Ye Tu

Journal of Actuarial Practice (1993-2006)

This paper studies the dynamic funding policy and investment strategy for defined benefit pension plans using one of the most comprehensive dynamic pension models to date. The model includes three investable assets: one risk free and two risky. The optimal plan decisions are formulated as a stochastic control problem that is solved using dynamic programming. The objective function uses performance measures to take into account the stability and solvency of the plan. The model is then applied to a Taiwanese pension.

Unearned Premiums And Deferred Policy Acquisition Expenses In Automobile Extended Warranty Insurance, Joseph Cheng

Journal of Actuarial Practice (1993-2006)

A prorata formula is commonly used to calculate unearned premium reserves in property-casualty insurance. I believe, however, that an exposure-adjusted formula is more appropriate in automobile extended warranties. This paper describes the exposure-adjusted approach to calculate the unearned premium reserves of an automobile extended warranty insurance program, to test the adequacy of the calculated reserves, and to determine the allowable deferred policy acquisition expenses from an insurance company's perspective.

Further Remarks On Risk Sources Measuring: The Case Of A Life Annuity Portfolio, Mariarosaria Coppola, Emilia Di Lorenzo, Marilena Sibillo

Journal of Actuarial Practice (1993-2006)

The paper considers a model that allows the actuary to measure the riskiness connected to the randomness of projected mortality tables in evaluating a portfolio of life annuities, obtaining a measure to reflect the risk associated with the randomness of the projection. The coherence of the risk parameters with the specific nature of the considered risk sources is also discussed. Numerical examples illustrate the results, showing the importance of the risk components in terms of the number of policies and comparing measure tools obtained by means of two procedures.

Improving Mortality: A Rule Of Thumb And Regulatory Tool, John H. Pollard

Journal of Actuarial Practice (1993-2006)

We develop a simple exact formula for determining cohort life expectancies under constant continuous uniform improvement in mortality using only a cross-sectional (period) Gompertz life table for the lives concerned and a simple approximation applicable to all life tables. The present values of annuities for such lives can be determined simply and accurately across the whole age span.

A Note On The Parallelogram Method For Computing The On-Level Premium, David P.M. Scollnik, Wai Man Sara Lau

Journal of Actuarial Practice (1993-2006)

This paper discusses the differences appearing in the descriptions of the parallelogram method for the determination of earned premium at current rate levels given by McClenahan (1996) and Brown and Gottlieb (2001). It observes that the former is consistent with the method of extending exposures while the latter is not. An illustration is provided. This paper also discusses two other approaches to the determination of the earned premium.

Model Risks And Surplus Management Under A Stochastic Interest Rate Process, Jennifer L. Wang, Rachel J. Huang

Journal of Actuarial Practice (1993-2006)

This paper uses simulations to explore the effects of incorrectly identifying the underlying interest rate process on assets, liabilities, and surplus levels. We show that mismodeling the interest rate (called model risk) could not only lead to a misstatement of the company's surplus, but could also cause a mismatch between the company's assets and liabilities. Our simulations demonstrate that three aspects of interest rates affect model risk: (i) volatility, (ii) level of long-term interest rate, and (iii) the speed at which the drift rate adjusts. We conclude that asset-liability managers should not ignore the impact of the model risks, regardless …

Adr Risk Characteristics And Measurement, Tom Arnold, Lance Nail, Terry D. Nixon

Finance Faculty Publications

While a healthy empirical literature exists on international diversification and its benefits, surprisingly few studies have examined the risk characteristics and efficacy of asset pricing models for one avenue of international diversification – investments in American Depository Receipts (ADRs). Originating in approximately 1927, ADRs provide an opportunity for investors to indirectly purchase shares of foreign firms. ADRs represent a claim to a given number of shares of a foreign firm held by a U.S. financial institution (e.g., Bank of New York). With the increasingly significant presence of ADR trading in the American stock markets – increasing six-fold between 1990 and …

Proposal For A Centralized And Integrated Registry For Security Interests In Intellectual Property, William J. Murphy

Law Faculty Scholarship

As the world economy enters the twenty-first century, job and wealth creation is increasingly based on innovation and creativity that, in turn, can give rise to important intellectual property rights. For many companies and individuals these intellectual property rights may represent their most valuable assets, or in some cases, their only valuable assets. As a result, intellectual property rights increasingly play a critical the role in financing.

Unlocking the job and wealth creating potential of intellectual property assets requires putting these assets into use, and that often requires a capital investment. Unfortunately, many entrepreneurs and innovators lack the capital necessary …

Can Utility-Maximization Models Assist With Retirement Planning?, Zaki Khorasanee

Journal of Actuarial Practice (1993-2006)

Utility-maximization models for optimizing portfolio choices can be subdivided into two classes: those based on maximizing the expected utility of lifetime consumption and those based on maximizing the expected utility of retirement wealth. It is argued that the first type of model, which optimizes both saving and investment decisions, is difficult to apply in practice because of inadequate (or unreliable) information about individual preferences. Although the second type of model only optimizes investment decisions, it is of greater practical value because fewer data on individual preferences are required. The second type of model is used to derive formulae for the …

Communicating Effectively With Words, Numbers, And Pictures: Drawing On Experience, Karolina Duklan, Michael A. Martin

Journal of Actuarial Practice (1993-2006)

In this paper, we discuss techniques for developing effective communication skills, focusing in particular on technical writing, the use of graphics, and presentation. The key principles of effective communication that we propose to actuaries are as follows:

• Identify your audience and consider their needs and abilities;

• Focus on substantive content;

• Choose appropriate communication tools;

• Use language that is simple, concrete, and familiar;

• Integrate text, numbers, and graphics;

• Respond to information complexity creatively.

We focus in particular on the use of graphics as a communications tool as they are an efficient and potentially highly effective …

Modeling Size-Of-Loss Distributions For Exact Data In Winbugs, David P.M. Scollnik

Journal of Actuarial Practice (1993-2006)

This paper discusses how the statistical software WinBUGS can be used to implement a Bayesian analysis of several popular severity models applied to exact size-of-Ioss data. The particular models targeted are the gamma, inverse gamma, loggamma, lognormal, (two-parameter) Pareto, inverse (two-parameter) Pareto, Weibull, and inverse Weibull distributions. It is possible to implement additional size-of-Ioss models (including those for truncated data) using methods analogous to those described herein.

Audit Committee Effectiveness: A Synthesis Of The Empirical Audit Committee Literature, F. Todd Dezoort, Dana R. Hermanson, Deborah S. Archambeault, Scott A. Reed

Accounting Faculty Publications

The empirical audit committee literature is both diverse and expansive, with rapid growth in recent years based on increased concerns about corporate governance and the quality of financial reporting. Our objective in this paper is to synthesize empirical literature on audit committee effectiveness to guide future thinking and research on audit committees. To organize our review, we focus on four components that we believe contribute to audit committee effectiveness (ACE) - audit committee composition, authority, resources, and diligence.

The Social Responsibility Of Large Multinational Corporations, Douglas M. Branson

Articles

In the 1970s, legal scholars wrote extensively on the subject, as it was then known, "corporate social responsibility." Proposals surfaced for pubic interest directors, mandatory social accounting and disclosure, increased use of Security Exchange Commission (SEC) shareholder proxy proposals, federal minimum debate was eclipsed completely by the law and economics movement of the 1980s. Now, in the new century, the inquiry into social responsibility of large corporations has begun anew. This article is an attempt to take that inquiry, or debate, and place it in the international context.
