Policymaking Network Of The Iron-Triangle Subgovernment For Licensing Hazardous Waste Facilities, F. Gregory Hayden

College of Business: Faculty Publications

The purposes here are to explain the linkage of (1) economic methodology, (2) corporate networks, and (3) federal court decisions in the licensing of hazardous waste facilities and to recognize the opportunity the combination of the three provides for institutional economists. The United States has the best and most comprehensive set of laws we might expect from a legislative process in order to prevent human disease, loss of property, and ecological system destruction from hazardous, toxic, and radioactive waste. Yet the licensing process and assessment that has grown out of that legislation has not produced the protection expected. The waste …

Financial Disclosure And Speculative Bubbles: An International Comparison, Benjamas Jirasakuldech, Thomas S. Zorn

Department of Finance: Faculty Publications

This paper examines if a country’s financial disclosure system affects the likelihood of speculative bubbles. We compare stock returns of eight countries that differ in the quality of their disclosure systems as ranked by Saudagaran and Biddle (1992). We examine the hypothesis that stock prices of firms in countries with a low level of financial disclosure are more prone to speculative bubbles. We employ the duration dependence model developed by McQueen and Thorley (1994) to test for the presence of bubbles. We found that the returns in Japan, a country with a relatively low level of disclosure, shows evidence of …

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.

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.

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 …

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.

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 …

Some Comments On The Pricing Of An Exotic Excess Of Loss Treaty, Jean-Francois Walhin

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 …

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.

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.

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.

The Need For And Meaning Of Positive Organizational Behavior, Fred Luthans

Department of Management: Faculty Publications

This essay draws from the emerging positive psychology movement and the author’s recent articles on the need for and meaning of a positive approach to organizational behavior. Specifically, the argument is made that at this time, the OB field needs a proactive, positive approach emphasizing strengths, rather than continuing in the downward spiral of negativity trying to fix weaknesses. However, to avoid the surface positivity represented by the non-sustainable best-sellers, the case is made for positive organizational behavior (POB) to take advantage of the OB field’s strength of being theory and research driven. Additional criteria for this version of POB …

Lmx And Subordinate Performance: The Moderating Effects Of Task Characteristics, Kenneth Dunegan, Mary Uhl-Bien, Dennis Duchon

Department of Management: Faculty Publications

Role conflict, role ambiguity, and intrinsic task satisfaction are found to moderate the relationship between leader–member exchange (LMX) and subordinate performance. Data from a field study of 146 supervisor–subordinate dyads indicate low conflict, high ambiguity, and high intrinsic satisfaction enhance the link between LMX and performance. Neutralizing effects are found when ambiguity and intrinsic satisfaction are low. High conflict appears to have a constraining effect, whereby the connection between LMX and performance is reduced but not neutralized. Results from the study call attention to the theoretical and practical benefits of examining the LMX/performance link from a contingency perspective, and offer …

What A Mess! Participation As A Simple Managerial Rule To “Complexify” Organizations, Donde Ashmos Plowman, Dennis Duchon, Reuben R. Mcdaniel Jr., John W. Huonker

Department of Management: Faculty Publications

This paper adopts a view of organizations as complex adaptive systems and makes a case for making organizations more complex internally through the use of a fairly simple managerial rule—using participative decision making. Participation in decision making enhances connectivity in organizations, which in turn, gives the organization the opportunity to self-organize and co-evolve in more effective ways than when there is minimal connectivity (i.e., autocracy). The paper uses a specific body of research to support the arguments about why participation can benefit the practice of management in modern organizations.

Impact Of Transformational Leadership On Follower Development And Performance: A Field Experiment, Taly Dvir, Dov Eden, Bruce Avolio, Boas Shamir

Department of Management: Faculty Publications

In a longitudinal, randomized field experiment, we tested the impact of transformational leadership, enhanced hy training, on follower development and performance. Experimental group leaders received transformational leadership training, and control group leaders, eclectic leadership training. The sample included 54 military leaders, their 90 direct followers, and 724 indirect followers. Results indicated the leaders in the experimental group had a more positive impact on direct followers' development and on indirect followers' performance than did the leaders in the control group.

Valuing The Arts: A Contingent Valuation Approach, Eric Thompson, Mark Berger, Glenn Blomquist, Steven Allen

College of Business: Faculty Publications

Government funding of the arts has received considerable attention in the United States in recent years. Efforts to cut funding to the National Endowment for the Arts and declining budgets for state arts agencies have raised questions about how much individuals value the arts. This paper applies the contingent valuation method to assess this value, using surveys of random households and of arts patrons. Our analysis estimated a mean willingness to pay (WTP) among all Kentucky households from $6 to $27, depending on the estimation technique used and on whether the scenario discussed is to increase arts performances by 25 …

The Influence Of Firm Dispositions On Interfirm Relationship Formation In Business Markets, Jean L. Johnson, Ravipreet S. Sohi

Department of Marketing: Faculty Publications

The central premise of this paper is that firm level characteristics or behavioral traits, referred to as predispositions, influence how the firm behaves and interacts in its interfirm relationships (EFRs). This augments traditional approaches that focus on the intra-relationship perspective and/or on environmental influences on the relationship. Firm predispositions of strategic intent and relational proclivity are expected to individually, and in combination, increase the extent of connectedness between partners in interfirm relationships. In turn, through connectedness, they affect relationship effectiveness in terms of reciprocity, information exchange, and cooperation. Results indicated that the predispositions increased connectedness, but combinational effects were not …

Analysis Of The Financial Assurance Plan In The License Application For A Low-Level Radioactive Waste Disposal Facility, F. Gregory Hayden, Scott Fullwiler

College of Business: Faculty Publications

Our purpose is to evaluate the efficiency of the financial assurance plan in the license application' submitted by American Ecology Corporation (AEC) to site, design, and build a new technological facility in Boyd County, Nebraska, for the disposal of low-level radioactive waste (LLRW). Efficiency means the ability to accomplish desired effects. Thus, efficiency considerations begin with social beliefs and ethics in order to know what is desirable. "Ethics can be considered a system of guidance designed to assist in living within a society. . . . That we must live together installs the positive requirement of doing good for one …

Assessing The Economic Understanding Of U.S. High School Students, William Walstad, Ken Rebeck

College of Business: Faculty Publications

Economics instruction in U.S. high schools is basically delivered in two ways. About half of high-school students take a required or elective course in economics, according to transcript data. The great majority of these students (about 95 percent) enroll in a regular course that focuses on basic economic concepts with applications. The remaining small percentage of students take a college-oriented course that is often called “honors” or Advanced Placement (AP) economics. Economics instruction for the other half of high-school students, if it is provided at all, is typically delivered in the context of other courses in the high-school curriculum in …

Research In Economic Education: Five New Initiatives, Michael K. Salemi, John J. Siegfried, Kim Sosin, William Walstad, Michael Watts

College of Business: Faculty Publications

Research is essential for improvement in teaching and learning economics. William E. Becker et al. (1991) called for new research on the relative merits of multiple-choice and essay tests, on the lasting effects of course work in economics, and on the effects of instructors, instructional techniques, and new technologies on student learning. To respond to the call, the Committee on Economic Education (CEE) of the American Economic Association recruited Robin Bartlett, William Becker, W. Lee Hansen, Peter Kennedy, and the authors to organize a conference that would jump-start new research projects.

Fitting Loss Distributions In The Presence Of Rating Variables, Farrokh Guiahi

Journal of Actuarial Practice (1993–2006)

This paper focuses on issues and methodologies for fitting alternative statistical models-parametric probability distributions-to samples of insurance loss data. The interactions of loss distributions, deductibles, policy limits, and rating variables in the context of fitting distributions to losses are discussed. Fitted loss distributions serve an important function in pricing insurance products. The methodology developed in this paper is applied to a sample of insurance loss data that has the lognormal as the underlying loss distribution.

Linear Empirical Bayes Estimation Of Survival Probabilities With Partial Data, Mostafa Mashayekhi

Journal of Actuarial Practice (1993–2006)

In this paper we consider linear empirical Bayes estimation of survival probabilities with partial data from right-censored and possibly left-truncated observations. Such data are produced by studies in which the exact times of death are not recorded and the length of time that each subject may be under observation cannot exceed one unit of time. We obtain asymptotically optimal linear empirical Bayes estimators, with respect to the squared error loss function, under the assumption that the probability of death under observation in a unit time interval is proportional to the length of observation. This assumption is sometimes implied by Balducci's …

A Sensitivity Analysis Of The Premiums For A Permanent Health Insurance (Phi) Model, Ben D. Rickayzen

Journal of Actuarial Practice (1993–2006)

This paper presents an analysis of the parameters used in a multi-state model for permanent health insurance (PHI). The model is a simplification of that used in the United Kingdom. To avoid using duration dependent probabilities, the model splits the sick state into several sub-states to act as a proxy for duration spent in a particular state. This enables a Markov approach to be adopted. Lapses are incorporated within the model, and the net premium for a particular policy is tested for sensitivity to the various parameters used, including their interaction with the lapse rate. One of our conclusions is …

Controlling The Solvency Interaction Among A Group Of Insurance Companies, Alexandros Zimbidis, Steven Haberman

Journal of Actuarial Practice (1993–2006)

Pooling of risks is an efficient risk management technique used by large employee benefit schemes of multinational companies to self-insure their retirement and other benefit obligations. This technique forms a basis for formulating a general control theoretic model for the interaction between insurance companies within a pooling network. The objective of these insurance companies is to avoid insolvency yet maintain stable premium and surplus processes. A general control system of equations that is used as a model for the interaction of m insurance companies within the network is first analyzed. An analytic solution is provided. Questions concerning the stability and …
