Obesity, Educational Attainment, And State Economic Welfare, Martin W. Sivula Ph.D. May 2004

Obesity, Educational Attainment, And State Economic Welfare, Martin W. Sivula Ph.D.

MBA Faculty Conference Papers & Journal Articles

For the first time in history, estimates of the overweight people in the world rival estimates of those malnourished. The World Health Organization (WHO, 2002) ranked obesity among the top 10 risks to human health worldwide. In the early 1960s, nearly half of the Americans were overweight and 13% were obese. Today some 64% of U.S. adults are overweight and 30.5% are obese. Even more alarming, twice as many U.S. children are overweight than were twenty years ago, a 66% increase. Non-communicable diseases impose a heavy economic burden on already strained health systems. Health is a key ...

The Actuarial Value Of Life Insurance Backdating, James M. Carson, Krzysztof Ostaszewski Jan 2004

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 ...


A Comparative Study Of Parametric And Nonparametric Estimators Of Old-Age Mortality In Sweden, Peter Fledelius, Montserrat Guillen, Jens Perch Nielsen, Kitt Skovso Petersen Jan 2004

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.


Estimation Of Complete Period Life Tables For Singaporeans, Siu-Hang Li, Wai-Sum Chan Jan 2004

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 ...


Decision Tree Analysis Of Terminated Life Insurance Policies, Robert Keng Heong Lian, Yuan Wu, Hian Chye Koh Jan 2004

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 ...


Product Innovation In Financial Services: A Survey, Christopher O'Brien Jan 2004

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 ...


Phased Retirement For Defined Benefit Plan Participants, Patricia L. Scahill, Jonathan Barry Forman Jan 2004

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 ...


Credibility Theory And Geometry, Elias S.W. Shiu, Fuk Yum Sing Jan 2004

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.


Rapid Calculation Of The Price Of Guaranteed Minimum Death Benefit Ratchet Options Embedded In Annuities, Eric R. Ulm Jan 2004

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 Jan 2004

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 ...
