The Effects Of Environment Dynamism And Heterogeneity On Salespeople's Role Perceptions, Performance And Job Satisfaction, Ravipreet S. Sohi

Department of Marketing: Faculty Publications

This article develops a structural equations model which examines the effects of environmental dynamism and heterogeneity on salespeople’s role conflict, role ambiguity, performance and job satisfaction. The model is tested with EQS, using data collected from 230 salespeople in multiple companies and industries. Indicates that environmental dynamism reduces satisfaction and performance, and increases role conflict and ambiguity. Notes that environmental heterogeneity also reduces performance and increases role conflict, but does not have a significant effect on role ambiguity.

Communication Flows In Distribution Channels: Impact On Assessments Of Communication Quality And Satisfaction, Jakki J. Mohr, Ravipreet S. Sohi

Department of Marketing: Faculty Publications

We develop and test a model of the relationships between: (1) norms of information sharing and communication flows of frequency, bidirectionality, and formality, (2) these communication flows and dealers’ assessments of the quality of communication and satisfaction with communication; and (3) formality of communication flows and dealers’ distortion and withholding of information. Based on data collected with a survey mailed to a national sample of computer dealers, our findings offer insight on channels communication to both researchers and practitioners. By examining the impact of communication flows on summary judgments of communication, managers can focus their efforts on vital communication flows …

Cross-Tested Defined Contribution Plans, Ho Kuen Ng

Journal of Actuarial Practice (1993–2006)

Cross-tested plans are defined contribution plans that test allocations for nondiscrimination. The test is based on a plan's actuarial equivalent annuity benefits. Cross-tested plans have become popular among small plan sponsors after the release of the nondiscrimination regulations. This paper investigates the pros and cons of cross-testing.

Discussion Of Ronald T. Kozlowski And Stuart B. Mathewson's "Measuring And Managing Catastrophe Risk", Rade T. Musulin

Journal of Actuarial Practice (1993–2006)

Mr. Kozlowski and Mr. Mathewson's paper provides a good introduction to the development and use of models in the property insurance industry. It will be a valuable addition to the regrettably sparse actuarialliterature in this area. This discussion will offer several comments on the ideas raised in the paper, focusing on how models can be used to enhance an actuary's work. The use of models has sparked major controversies between regulators and insurers in several jurisdictions, notably Florida. Controversy is not limited to the regulatory arena, however. Because models are being used by reinsurers to rate contracts and by A.M. …

Decision Making Under Conflicting Criteria In Pension Valuations: An Expected Utility Model, Lisa Lipowski Posey, Arnold F. Shapiro

Journal of Actuarial Practice (1993–2006)

Many of the criteria used by actuaries when selecting assumptions for pension plan valuations often conflict. As a result, actuaries must weigh the various costs and benefits associated with a particular set of assumptions. We use expected utility theory to model the process of chOOSing actuarial assumptions when faced with potentially conflicting criteria. The three criteria considered are prudence, best estimate, and conservatism. The actual contribution chosen by the actuary is found to depend on the contribution level that triggers a red flag with respect to tax deductibility. If this level is relatively low, the actuary chooses a high contribution …

Sensitivity Testing Of Prdperty/Casualty Cash Flows, Ralph S. Blanchard Iii, Eduardo P. Marchena

Journal of Actuarial Practice (1993–2006)

The paper outlines an approach that has evolved at Aetna through ten years of property/casualty insurance cash flow testing. Methodologies and approaches to setting parameters reflecting both default and call/prepayment risk are discussed for major invested asset categories. Modeling runoff cash flows for a base scenario (and, for some of these assets, shocked scenarios) also is examined for major non-invested asset categories. Loss reserve cash flow modeling is not addressed, except for a brief description of one approach to shocking projected flows. Finally, various alternatives are given for presenting cash flow testing results to management and non-actuarial audiences.

Surveillance Of Life Insurer Solvency: A Comparison Of Stock And The Multiple Scenario Cash Flow Financial Stress Tests, Ronald W. Spahr, Paul L. Gronewoller

Journal of Actuarial Practice (1993–2006)

The solvency of life insurance companies may be threatened by interest rate risk when the maturities of assets and liabilities are mismatched. The National Association of Insurance Commissioners' (NAIC) multiple scenario cashflow test (MSCFT) and the Office of Thrift Supervision (OTS) net portfolio value model (stock) approaches to financial stress tests are illustrated and analyzed with respect to their capacity to estimate the impact of potential changes in interest rates on life insurance company capital and surplus. Each approach is illustrated with the assets and liabilities of three hypothetical life insurance company capital levels (high, average, and below average) and …

Hiv, Aids, Markov Processes, And Health And Disability Insurance, Steven Haberman

Journal of Actuarial Practice (1993–2006)

This paper presents a Markov model of the transmission and development of HIV and AIDS. The Markov model is used to derive functions needed in the calculation of disability insurance premiums, reserves, and cash flows. An application to health insurance and disability insurance is provided.

Life Insurer Risk-Based Capital: An Option Pricing Approach, Samuel H. Cox, Arthur M.B. Hogan

Journal of Actuarial Practice (1993–2006)

This paper uses an option pricing framework to estimate life insurer risk-based capital. Stock market data and statutory asset and liability data are used to calculate the implied level of statutory risk-based capital for each of 18 insurers. We calculate the level of risk-based capital required to avoid subsidy from the guaranty fund. Our results suggest that less capital is required than that required under the New York actuarial risk-based capital formula. Firm rankings, however, are similar under both methods, although the methods are not directly comparable. We also determine the level of capital required if the subsidy provided to …

Model Year Rating For Automobile Liability And Injury Coverages, Leonard T. Guarini, Edward P. Lotkowski

Journal of Actuarial Practice (1993–2006)

This paper is intended to stimulate further research and discussion on the validity and utility of model year rating for personal automobile coverages other than physical damage. Using data from a single insurer and some elementary statistical techniques, we provide evidence supporting model year as a classification variable for automobile liability and injury coverages.

Actuarial Conservatism: Not In Public Sector Defined Benefit Pension Plans, Brian A. Jones

Journal of Actuarial Practice (1993–2006)

Most actuaries tend to be conservative, and most, including this writer, probably would be happy to be so categorized. But actuarial conservatism may not be the best rule in defined benefit public sector pension plans. This paper argues that it is not appropriate for actuaries to employ conservatism assumptions in such public sector plans.

A Pension Plan Incorporating Both Defined Benefit And Defined Contribution Principles, Zaki M. Khorasanee

Journal of Actuarial Practice (1993–2006)

We propose a defined contribution pension plan with an explicitly defined benefit formula. Such a plan is expected to pay more stable and predictable benefits over time than one based on the money purchase principle. The properties of the plan are investigated through simulation. Methods for distributing surpluses and eliminating deficiencies that involve adjusting the rate of benefit accrual (rather than varying the rate of contribution) are discussed. The behavior of the plan under a scenario of persistently unfavorable investment experience is Simulated, and methods for satisfactorily dealing with such a scenario are considered. The plan actuary is expected to …

Measuring And Managing Catastrophe Risk, Ronald T. Kozlowski, Stuart B. Mathewson

Journal of Actuarial Practice (1993–2006)

We introduce some of the basic principles behind property catastrophe modeling via simulations. The output of such simulations can be explored via modernized pin maps and loss likelihood curves. We also briefly discuss some of the uses of catastrophe modeling in addition to traditional probable maximum loss estimation. Comments are made on the use of modeling by reinsurers. We hope that this article stimulates discussions on new approaches to catastrophe modeling.

Simulation Of Investment Returns For A Money Purchase Fund, Zaki M. Khorasanee

Journal of Actuarial Practice (1993–2006)

This paper examines the problem of investment risk in money purchase pension plans. The disadvantages of modeling equity returns as independent, identically distributed random variables are conSidered, and a modified stochastic model of equity returns is proposed. This modified stochastic model is used to estimate the variability in a plan member's retirement fund and to compare various alternatives to investing 100 percent of the assets in ordinary shares. Varying conclusions are drawn about the likely success of these alternative investment strategies in reducing investment risk.

Recent Canadian Human Rights Decisions Having An Impact On Gender-Based Risk Classification Systems, Robert L. Brown

Journal of Actuarial Practice (1993–2006)

With the passage of the Canadian Charter of Rights and Freedoms on April 17, 1982, all previous court precedents using gender in risk classification systems became obsolete. Three cases involving issues of discrimination in the use of age and gender now clarify the position of the Canadian judiciary. Based on the decisions in these three cases, this paper presents arguments that can be used in any jurisdiction to defend successfully the use of gender in a property /casualty risk classification system.

Discussion Of Robert L. Brown's "Recent Canadian Human Rights Decisions Having An Impact On Gender-Based Risk Classification Systems", Patrick Butler

Journal of Actuarial Practice (1993–2006)

This commentary examines the political and economic influence of demographic groups on rationales for granting exemption from laws prohibiting classification by age or sex, as evidenced in the cases discussed by Robert L. Brown. Age is less subject than sex to manipulation for group advantage. In Professor Brown's discussion of auto insurance cases, only the influence of group dominance can explain:

• Selective focus on young drivers;

• Indifference to ongoing overcharging of adult women signaled by undisputed 2:1 ratios of cost-related averages; and

• Avoidance of effective ways to evaluate miles of exposure to risk.

Contrary to Professor Brown's …

Obtaining A Life Table For Spinal Cord Injury Patients Using Information Theory, Patrick L. Brockett, Yun Song

Journal of Actuarial Practice (1993–2006)

We present a mortality table adjustment method based on a constrained information theoretic methodology. The objective is to adjust a standard mortality table to reflect a particular known characteristic of the population while remaining as close as possible to a given standard table. To illustrate these techniques, the medical results concerning survival of spinal cord injury patients are incorporated into a standard table to obtain a mortality table pertinent for paraplegic and quadriplegic individuals. The desired adjusted mortality table can be used by actuaries for special purposes such as wrongful injury damage award compensation calculations and determining life insurance premium …

Expected Loss Development In Workers' Compensation Pricing: A Shift In Credibility, Christopher J. Poteet

Journal of Actuarial Practice (1993–2006)

This paper shows that expected loss development is equivalent to adjusting the full credibility standard and applying credibility by policy period. Expected loss development should not be used in workers' compensation ratemaking. The credibility is correct before being adjusted.

Obligations And Penalties Under Lemon Laws: Automobiles Versus Tractors, Terence J. Centner, Michael E. Wetzstein

Department of Agricultural Economics: Faculty Publications

Distinctive new provisions of tractor lemon laws which create obligations and provide penalties for defective self-propelled agricultural equipment are contrasted with provisions of automobile lemon laws. Lemon-law obligations involve both producers' guarantees to provide consumers with a serviceable vehicle and producers' promises to remedy defects. Due to fewer manufacturer obligations under the tractor lemon laws as opposed to automobile lemon laws, tractors may be expected to have more defects than automobiles. Yet the tractor lemon laws contain fewer penalties in the form of restitution remedies. The inconsistences of these obligations and penalties suggest tractor laws may be inefficient.

Salespersons’ Perceptions About Sales Contests: Towards A Greater Understanding, William H. Murphy, Ravipreet S. Sohi

Department of Marketing: Faculty Publications

Aims to improve understanding of an important and widely used management tool for motivating the salesforce – sales contests. Begins by introducing the question: what factors are associated with salespeople's feelings towards a sales contest? Several potentially relevant characteristics that are expected to be associated with various feelings towards contests are discussed. To test the hypotheses, data were collected through verbal protocols and surveys from salespeople belonging to a division of a Fortune 100 firm. Results indicate that salespeople's self-esteem, commitment level, and career stage play a role in influencing feelings towards the sales contest.

The impetus for this research …

Relationship-Based Approach To Leadership: Development Of Leader-Member Exchange (Lmx) Theory Of Leadership Over 25 Years: Applying A Multi-Level Multi-Domain Perspective, George B. Graen, Mary Uhl-Bien

Department of Management: Faculty Publications

Research into Leader-Member Exchange (LMX) theory has been gaining momentum in recent years, with a multitude of studies investigating many aspects of LMX in organizations. Theoretical development in this area also has undergone many refinements, and the current theory is far different from the early Vertical Dyad Linkage (VDL) work. This article uses a levels perspective to trace the development of LMX through four evolutionary stages of theorizing and investigation up to the present. The article also uses a domains perspective to develop a new taxonomy of approaches to leadership, and LMX is discussed within this taxonomy as a relationship-based …

Women And The Great Retrenchment: The Political Economy Of Gender In The 1980s, Ann Mari May

College of Business: Faculty Publications

Policy analysts and scholars are only now beginning the serious task of sifting through the debris of the 1980s to chronicle the impacts of policy chtinges and to evaluate the policies as well as the policymakers. The 1980s will no doubt be remembered as having produced the worst recession since the Great Depression and perhaps, more generally, as a period of economic retrenchment [Dugger 1992]. While many segments of society were affected by the restructuring inherent in Reaganomics, the impact on women merits special attention, particularly in light of demographic changes in voting behavior. It has long been understood that …

Achievement Differences On Multiple-Choice And Essay Tests In Economics, William Walstad, William E. Becker

College of Business: Faculty Publications

Multiple-choice and essay tests are the typical test formats used to measure student understanding of economics in college courses. Each type has its features. A multiple- choice (or fixed-response) format allows for a wider sampling of the content because more questions can be given in a testing period. Multiple-choice tests also offer greater efficiency and reliability in scoring than an essay. The major disadvantage of a multiple-choice item is that the fixed responses tend to emphasize recall and encourage guessing. In an essay (or constructed- response) test, students generate responses that have the potential to show originality and a greater …
