Fuzzy Knowledge-Based Approach To Treating Uncertainty In Inventory Control, Dobrilla Petrovic, Edward Sweeney

Articles

Inventory control in complex manufacturing environments encounters various sources of uncertainity and imprecision. This paper presents one fuzzy knowledge-based approach to solving the problem of order quantity determination, in the presence of uncertain demand, lead time and actual inventory level. Uncertain data are represented by fuzzy numbers, and vaguely defined relations between them are modeled by fuzzy if-then rules. The proposed representation and inference mechanism are verified using a large numbers of examples. The results of three representative cases are summarized. Finally a comparison between the developed fuzzy knowledge-based and traditional, probabilistic approaches is discussed.

Managing The Costs And Risks Of Housing Finance: A New Role For Actuaries, Anthony Asher

Journal of Actuarial Practice (1993–2006)

Housing finance is a nontraditional field where actuarial expertise could be applied fruitfully. The development of mortgage instruments requires the application of financial mathematics, while the evaluation and management of the financial risks to which borrowers and lenders are exposed require a knowledge of insurance principles. This paper splits the financial costs of home ownership into several components: those that arise from inflation, risk, administration, and the residual real interest charge. The risk component further is partitioned into life contingencies, economic contingencies, and various moral hazards. This analysis provides a basis for future financial innovation, highlights where government intervention may …

Health Insurance Reform And Its Effects On The Small Employer Market: A Review Of H.R. 3626, Anthony P. Hammond

Journal of Actuarial Practice (1993–2006)

This paper provides a detailed analysis of H.R. 3626, a bill that is intended to improve employers' and employees' access to health care. H.R. 3626 attempts to accomplish this through the use of guaranteed availability, community rating, and generous standard benefits. A migration model is used to analyze the impact of H.R. 3626. Using this model, it is shown that while improving the availability and affordability of health insurance, its rating restrictions increase premiums disproportionately for the majority of small employers. In addition, H.R. 3626 increases the number of uninsured small employers.

The Markov Chain Interest Rate Scenario Generator Revisited, Sarah L.M. Christiansen

Journal of Actuarial Practice (1993–2006)

This paper furthers the development of the Markov chain interest rate generator. Though the basic technique remains essentially unchanged, there are still many significant changes to the model. For example: (i) the long (key) rates are now are generated by a mean reversionary process; (ii) the number of shapes is increased from seven to 11; (iii) the limitation of changing by only two shape codes per year is removed; and (iv) the random walk matrix that determines the shapes is revised to be more realistic. An algorithm is developed to determine the shape code of the original yield curve, thus …

An Introduction To Individual Disability Income Insurance, Mark J. Chartier

Journal of Actuarial Practice (1993–2006)

There are several actuarial software packages purporting to calculate expected benefit cash flows on disability income insurance policies. To the author's knowledge, however, there is no published text that explains how to perform these calculations. This paper is intended to fill this gap in the literature. It describes some of the more common techniques for pricing disability income insurance. Those techniques for which claim costs can be used and those for which the pricing actuary must project cash flows are identified.

Tax Assistance To Qualified Retirement Savings Plans: Deferral Or Waiver?, Robert L. Brown

Journal of Actuarial Practice (1993–2006)

There exist significant tax incentives for retirement savings plans in Canada and the United States. Qualified employer and employee contributions, within limits, are tax deductible to the employer and nontaxable to the employee. Also, investment income is not taxed until taken. On the other hand, monies received from funds having such tax incentives are taxable in full as income to the recipient when taken. This paper analyzes the two tax advantages of qualified retirement savings plans: the tax deductibility of contributions and the nontaxation of investment income until it has been distributed. The algebraic analysis shows that the deductibility of …

Safety First And Ambiguity, Lawrence A. Berger, Howard Kunreuther

Journal of Actuarial Practice (1993–2006)

There is considerable empirical evidence suggesting that ambiguity (i.e., parameter risk) impacts pricing decisions by actuaries and underwriters and their desire to provide coverage. Stone proposed a safety first model of choice that provides a possible explanation for this behavior. This paper analyzes Stone's proposed stability and survival constraints and compares the results with those predicted by expected utility theory. The analysis is motivated by insurers' increasing reluctance to provide coverage for certain specific risks such as earthquake damage insurance where the probability of loss is ambiguous. We show that such behavior is consistent with safety first but is difficult …

Reconciling Two Rate Level Indications: A Chain Rule Approach, Cheng-Sheng Peter Wu

Journal of Actuarial Practice (1993–2006)

The problem considered is that of reconciling two rate level indications that are based on several common factors, but have been made at different review periods. A popular approach to this problem is the so-called sequential replacement method, which calculates the impact of each individual factor. Unfortunately, this method has a serious deficiency: the estimated impact of a factor depends upon the order of the replacement. To counteract this defect, a new approach, called the chain rule approach, is developed. Using this approach, an explicit formula is given for calculating the impact and the marginal impact of each factor.

Modal Premium Factors In Ordinary Life Insurance, James B. Ross, Criss G. Woodruff

Journal of Actuarial Practice (1993–2006)

For ordinary life policyholders who want to pay more frequently than annually, insurers construct schedules of modal premium factors that reflect additional charges for the costs of collection, forgone interest, and premiums uncollected or refunded in the year of death. Competition within the industry forces convergence of such schedules. On the other hand, if such factors for a given company reflect its own experience (in expense, interest, mortality, and persistency), the differences between companies will force schedules apart. Analysis of a large group of life insurers over the 1972-1982-1992 period shows that modal premium factors are dustered closely, that they …

Cost Containment In Workers' Compensation: Evaluating Medical Fee Schedules, David L. Durbin, Barry I. Llewellyn

Journal of Actuarial Practice (1993–2006)

Medical expenditures in workers' compensation programs have been subjected to few cost containment strategies. As workers' compensation costs have escalated, however, increasing attention is being given to the role of medical fee schedules in containing the prices of medical services. To this end, we develop a model for estimating the potential cost savings from implementing medical fee schedules. A market basket of medical services received by injured workers is constructed. This basket is used to estimate the parameters of the model. In addition, the basket is used to determine the impact of imposing a fee schedule linked to usual and …

Predicting Automobile Insurance Multi-Regional Base Pure Premiums, Edward Nissan, Iskandar S. Hamwi

Journal of Actuarial Practice (1993–2006)

Multi-regional insurance base premiums are customarily computed by a top-down method where national or state projections are adjusted to reflect regional differences. This paper proposes a methodology for a bottom-up projection. A weighing scheme that minimizes the variance of the estimator is suggested as a criterion to establish an overall multi-regional rate.

Modeling Insurance Cash Flows For Universal Life Policies, Robert E. Hoyt

Journal of Actuarial Practice (1993–2006)

This paper develops a methodology that can be used by insurers to construct predictive models for their own insurance cash flows. The insurance cash flow components evaluated include premium flows, policy loans, and cash value surrenders. Also, the paper evaluates several hypotheses in the insurance literature that attempt to explain insurance cash flows. Though the results are theoretically consistent, they produce some interesting contrasts to findings of similar studies for whole life policies. For example, these results confirm that: (i) the credited rate strategy is important to policy performance; (ii) the emergency fund hypothesis appears to apply to policy loan …

A Statistical Approach To Ibnr Reserves, Bradford S. Gile

Journal of Actuarial Practice (1993–2006)

This paper develops a three dimensional statistical approach to the estimation of the mean and the standard deviation of pure incurred but not reported (IBNR) reserves. This means that the time of occurrence, the reporting lag, and the claim severity are separately modeled. It is assumed that, beyond any fixed time t, the claim number development process is Poisson and that the severity of loss depends on the length of the reporting lag. Two key assumptions are made to simplify the estimation of model parameters: for a given reporting lag, (i) the conditional mean of the claim size is a …

Discussion Of Robert L. Brown's "Tax Assistance To Qualified Retirement Savings Plans: Deferral Or Waiver"*, Mark W. Campbell

Journal of Actuarial Practice (1993–2006)

In the paper entitled "Tax Assistance to Qualified Retirement Savings Plans: Deferral or Waiver," Robert L. Brown concludes that "the nontaxation of investment income on qualified funds until taken is a tax waiver or tax subsidy from the government to participants of qualified plans". I believe, however, that this conclusion is based on flawed assumptions pertaining to:

• The behavioral responses of taxpayers to the withdrawal of such tax assistance;

• The definition of an appropriate benchmark tax system against which to measure the cost of such tax assistance; and

• The appropriate basis of comparison of alternative government tax …

Disenrollment Patterns Of Elderly In Managed Care And Fee For Service, Kenneth G. Manton, Dennis H. Tolley, Robert Newcomer, James C. Vertrees, Charlene Harrington

Journal of Actuarial Practice (1993–2006)

As the trend to provide health care through managed care facilities increases, the need to examine ,vhy insured individuals voluntarily terminate managed care coverage grows. Voluntary termination of coverage, or dis enrollment, has both social and fiscal implications. Particularly among the elderly, patterns of disenrollment likely are related to self assessment of care needs and levels of health. In this paper we examine the patterns of dis enrollment among elderly enrollees as a function of health status and disability. We focus on disenrollment patterns from an experimental prepaid extended care facility, called a social HMO (S/HMO) and compare this pattern …

The Evolution Of Shopping Center Research: A Review And Analysis, Mark Eppli, John D. Benjamin

Finance Faculty Research and Publications

Retail research has evolved over the past sixty years. Christaller's early work on central place theory, with its simplistic combination of range and threshold has been advanced to include complex consumer shopping patterns and retailer behavior in agglomerated retail centers. Hotelling's seminal research on competition in a spatial duopoly has been realized in the form of comparison shopping in regional shopping centers. The research that has followed Christaller and Hoteling has been as wide as it has been deep, including literature in geography, economics, finance, marketing, and real estate.

In combination, the many extensions of central place theory and retail …

The Individual Investor : Investment Objectives, Strategies, And Tactics, Clive Walcott

Theses

The individual investor's circumstances and investment behavior have received relatively little attention since it was discovered in the late sixties that he was withdrawing as a direct participant in the American equities market. The first major response to this withdrawal phenomenon was the 1974 Individual Investor Research Project (IIRP). For the first time, the individual investor's circumstances and decision processes were examined directly and not through broad-based trading statistics or portfolio simulations.

This current survey identifies the significant changes in investment objectives, strategies, and tactics since the IIRP. These changes were discovered when seven demographic variables were cross-classified with various …

Investor Views Of Audit Assurance: Recent Evidence Of The Expectation Gap, Marshall A. Geiger

Accounting Faculty Publications

Investors and financial statement users long have agreed on the usefulness of the audit in financial reporting. Over time, however, auditors have been expected to provide assurance in varying degrees and for different purposes. Differences in perception -- especially regarding assurances provided -- between users, preparers and auditors have been termed the "expectation gap. This article provides some startling evidence of the existence of such a gap in investor perceptions of the assurance provided by an audit.

Employment-Based Health Insurance And Job Mobility: Is There Evidence Of Job-Lock?, Brigitte C. Madrian

Faculty Publications

This paper assesses the impact of employer-provided health insurance on job mobility by exploring the extent to which workers are "locked' into their jobs because preexisting conditions exclusions make it expensive for individuals with medical problems to relinquish their current health insurance. I estimate the degree of job-lock by comparing the difference in the turnover rates of those with high and low medical expenses for those with and without employer-provided health insurance. Using data from the 1987 National Medical Expenditure Survey, I estimate that job-lock reduces the voluntary turnover rate of those with employer-provided health insurance by 25 percent, from …

The Effect Of Health Insurance On Retirement, Brigitte C. Madrian

Faculty Publications

FOR DECADES health insurance in the United States has been provided to most nonelderly Americans through their own or a family member's employment. This system of employment-based health insurance has evolved largely because of the substantial cost advantages that employers enjoy in supplying health insurance. By pooling large numbers of individuals, employers face significantly lower administrative expenses than do individuals. In addition, employer expenditures on health insurance are tax deductible, but individual expenditures are generally not.¹

Despite these cost advantages, there is widespread dissatisfaction with this system of employment-based health insurance. Many people are excluded because not all employers …

The Vehicle Quota System In Singapore: An Assessment, Winston T. H. Koh, David K. C. Lee

Research Collection Lee Kong Chian School Of Business

This paper reviews the developments since the vehicle quota system was introduced in Singapore in May 1990. We discuss the bidding strategies for the certificates of entitlement (COE) under both the transferable and nontransferable auctions, as well as the equity of the present system and the desirability of transferable COEs. We argue that the COE auction should be made discriminatory and propose an alternative system of COE auction that we feel is both equitable and at the same time politically acceptable. We also survey developments in market competition in the car industry.

Cost Overrun Optimism: Fact Or Fiction, David D. Christensen

Faculty Publications

Program managers are advocates by necessity, When taken to the extreme, program advocacy can result in the suppression of adverse information about the status of a program gram. Such was the case in the Navy's A-12 Program. In A-12 Administrative inquiry, Beach (1990) speculates that such abiding cultural problems were not unique to the Navy. To test that assertion, this paper examines cost overrun data on 64 completed acquisition contracts extracted from the Defense Acquisition Executive Summary database. Cost overruns at various contract completion points are compared with projected final cost overruns estimated by contractor and government personnel. 17 comparison …

Is A Bond Rating Downgrade Bad News, Good News, Or No News For Stockholders?, Choo Yong, Jeremy Goh, Louis H. Ederington

Research Collection Lee Kong Chian School Of Business

We examine the reaction of common stock returns to bond rating changes. While recent studies find a significant negative stock response to downgrades, we argue that this reaction should not be expected for all downgrades because: (1) some rating changes are anticipated by market participants and (2) downgrades because of an anticipated move to transfer wealth from bondholders to stockholders should be good news for stockholders. We find that downgrades associated with deteriorating financial prospects convey new negative information to the capital market, but that downgrades due to changes in firms' leverage do not.
