Modeling Clusters Of Extreme Losses, Beatriz Vaz De Melo Mendes, Juliana Sa Freire De Lima

Journal of Actuarial Practice (1993–2006)

We model extreme losses from an excess of loss reinsurance contract under the assumption of the existence of a subordinated process generating sequences of large claims. We characterize clusters of extreme losses and aggregate the excess losses within clusters. The number of clusters is modeled using the usual discrete probability models, and the severity of the sum of excesses within clusters is modeled using a flexible extension of the generalized Pareto distribution. We illustrate the methodology using a Danish fire insurance claims data set. Maximum likelihood point estimates and bootstrap confidence intervals are obtained for the parameters and statistical premium. …

A Primer On Duration, Convexity, And Immunization, Leslaw Gajek, Krzysztof Ostaszewski, Hans-Joachim Zwiesler

Journal of Actuarial Practice (1993–2006)

The concepts of duration, convexity, and immunization are fundamental tools of asset-liability management. This paper provides a theoretical and practical overview of the concepts, largely missing in the existing literature on the subject, and fills some holes in the body of research on the subject. We not present new research, but rather we provide a new presentation of the underlying theory, which we believe to be of value in the new North American actuarial education system.

Optimal Dividend Strategies: Some Economic Interpretations For The Constant Barrier Case, Maite Marmol, M. Merce Claramunt, Antonio Alegre

Journal of Actuarial Practice (1993–2006)

We consider the surplus process of a non-life insurance portfolio with a dividend component represented by a constant dividend barrier strategy. The optimal dividend barrier is known when individual claim amounts follow an exponential distribution. This result for the optimal dividend barrier is used to develop combinations of the levels of the insurer's initial surplus and of the barrier which, under certain economic and financial criteria, can be regarded as optimal.

A New Hybrid Defined Benefit Plan Design, Wayne E. Dydo

Journal of Actuarial Practice (1993–2006)

Traditional defined benefit plans can be difficult to understand and complex to administer. Hybrid plans (cash balance and pension equity) arose in part to address the former issue, but at a price of greater administrative and litigation risk. I introduce a design for defined benefit pension plans that is easy to communicate to participants, allows for accrual patterns that closely replicate those of the two most common forms of hybrid pension plans, and avoids the controversial nondiscrimination issues that currently trouble sponsors of hybrid plans. The design defines the benefit as a fixed percentage of pay payable over a period …

Risk-Based Regulatory Capital For Insurers: A Case Study, Christian Sutherland-Wong, Michael Sherris

Journal of Actuarial Practice (1993–2006)

We study the issues in determining regulatory capital requirements using advanced modeling by assessing and comparing capital requirements under the two alternative approaches. A dynamic financial analysis (DFA) model is used for this case study. These issues are of current international interest as regulators, insurers, and actuaries face the significant issues involved with the introduction of risk-based capital for insurers.

Reputation Pricing: A Model For Valuing Future Life Insurance Policies, Rami Yosef

Journal of Actuarial Practice (1993–2006)

The reputation of a life insurer is used to develop a model for determining the value of future life insurance policies. An M / G / 00 process is used to describe the sales and terminations (due to death or maturity) of future policies. The intensity of the arrival process is assumed to depend on the company's reputation. Explicit expressions are derived for the actuarial reserves and expected profits of these future policies.

On The Pricing Of Top And Drop Excess Of Loss Covers, Jean-Francois Walhin, Michel Denuit

Journal of Actuarial Practice (1993–2006)

A top and drop cover is a treaty that can be found on the retrocession market. It offers capacity that can be used either to protect a top layer or a working layer. The former is called a "top" and the latter is called a "drop." Using the traditional collective risk model, we demonstrate the use of a multivariate version of Panjer's algorithm to price this cover. We also compare the premium obtained within the exact model with the premiums obtained either with the Frechet bounds or with the wrong assumption of independence.

An Application Of Control Theory To The Individual Aggregate Cost Method, Alexandros A. Zimbidis, Steven Haberman

Journal of Actuarial Practice (1993–2006)

The paper investigates the individual aggregate cost method (also known as the individual spread-gain method), which is normally applicable in small pension funds or fully contributory schemes, using a control theoretical framework. We construct the difference equations describing the mechanisms of the respective funding method and then calculate the optimal control path of the contribution rate assuming (first) a stochastic and (second) a deterministic pattern for the future investment rates of return. For the first case, the optimal solution is achieved through a linear approximation and using stochastic optimization techniques. It is proved that the contribution rate is (optimally) controlled …

Modeling Insurance Loss Data: The Log-Eig Distribution, Uditha Balasooriya, Chan Kee Low, Adrian Y.W. Wong

Journal of Actuarial Practice (1993–2006)

The log-EIG distribution was recently introduced to the probability literature. It has positive support and a moderately long tail, and is closer to the lognormal than to the gamma or Weibull distributions. Our simulations show that data generated from a log-EIG distribution cannot be adequately described by lognormal, gamma, or Weibull distributions. The log-EIG distribution is a worthwhile candidate for modeling insurance claims (loss) data or lifetime data. Examples of fitting the log-EIG to published insurance claims data are given.

A Modern Approach To Modeling Insurances On Two Lives, Maria Bilikova, Graham Luffrum

Journal of Actuarial Practice (1993–2006)

The analysis of life insurance contracts on two lives using the traditional deterministic approach has been an important part of actuarial education for the past fifty years or more. Recently there has been a shift from this deterministic approach to one using a more modern stochastic approach involving the future lifetime random variable. In this paper we will look at the problem using multiple-state models. In our view this approach allows a deeper analysis than either the traditional or the random future lifetime ones.

Ultimate Ruin Probability For A Time-Series Risk Model With Dependent Classes Of Insurance Business, Lai Mei Wan, Kam Chuen Yuen, Wai Keung Li

Journal of Actuarial Practice (1993–2006)

We consider a discrete-time risk model with m (m ~ 2) dependent classes of insurance business. The claim processes of these m classes are assumed to follow a multivariate autoregressive time-series model of order 1. Given this claims model, we explore the probability of ultimate ruin assuming exponentially bounded claims. As an example, we use simulations to study the case where there are two business and the underlying losses are of two types: bivariate exponential and bivariate gamma claim distributions.

Masculinity In The Making: Men’S Increased Consumption Of Strength Training, Roger Sherlock, Olivia Freeman, Andrew Dunne

Conference papers

This paper explores the relationship between the body, masculinity and the consumption of body-focussed activities. It examines the meaning and importance of strength training for men. Strength training is of interest because its increase in popularity is occurring at a particular point in time when a growing number of men are experiencing insecurities over their masculine identities as a result of recent socioeconomic changes. This paper proposes that men today are facing a dilemma in terms of masculine identity. This dilemma hinges on the growing objectification of the male body in the media and its cultural messages regarding masculinity.

A System Dynamics Approach To Assessing Public Policy Impact On The Sustainable Growth Rate Of New Ventures, Jeff W. Trailer, Kuau Garsson

New England Journal of Entrepreneurship

The growth of firms is fundamentally based on self-reinforcing feedback loops, one of the most important of which involves cash flow. When profit margin is positive, sales generate cash, which may then be reinvested to finance the operating cash cycle. We analyze simulations of a sustainable growth model of a generic new venture to assess the importance of taxes, and regulatory costs in determining growth. The results suggest that new ventures are particularly vulnerable to public policy effects, since their working capital resource levels are minimal, and they have few options to raise external funds necessary to fuel their initial …

Everything You Always Wanted To Know About Ipos* But Were Afraid To Ask, Joseph E. Levangie

New England Journal of Entrepreneurship

Many entrepreneurs want to reach high to the heavens to achieve unlimited success. These hardworking, often underappreciated, venturers often crave fame and fortune as they strive to create their personal business legacy. One strategic path many have wandered down is that of the Initial Public Offering (IPO), whereby shares of the company are sold to the public. The IPO has many strong attractions. Large amounts of capital can be brought into the company.The company’s stock can be used as currency to acquire other companies. Early investors realize a good ROI. Employees can perceive real value in their stock options. Customers, …

Basel Ii And The Need For Bank Distress Resolution Procedures, Clas Wihlborg

Business Faculty Articles and Research

It is argued that without increased market discipline Basel II is not likely to resolve the regulatory problem caused by explicit and implicit guarantees of depositors and other creditors of banks. One way to enhance market discipline is to implement proposals for mandatory subordinated debt. For these proposals to achieve their objective, the non-insurance of holders of subordinated debt must be credible. Increased credibility of non-insurance of one or several groups of creditors could be enhanced if distress resolution procedures for banks were pre-specified, and if they made possible bank failures without serious disruption of the financial system. The existence …

Solving The Bargaining Democracy Problem Using A Constitutional Hierarchy Of Law, Clas Wihlborg

Business Faculty Articles and Research

In the “bargaining democracy” groups form coalitions that are able to grant benefits to themselves through legislation. These benefits may lack popular support. A constitutional hierarchy of conflicting laws is proposed to resolve this democratic problem. In the hierarchy more “rule-oriented” legislation dominate. The hierarchy would create a momentum of the political process towards more rule-oriented legislation and policy debate. The difficulty of defining a rule operationally is overcome by limiting the task of a constitutional court to simply rank conflicting policy actions in terms of criteria for rules.

An Examination Of Facilitators And Inhibitors To Knowledge Sharing In A Policing Environment : Lessons From Intelligence-Led Crime Management Units Of The Western Australia Police Service, Vince Hughes

Theses: Doctorates and Masters

The objective of this research project was to gain an understanding of the inhibitors and facilitators to knowledge sharing within a policing environment. Although it did not begin with the intention of applying interverntions of any kind, in the course of the thesis it became clear that a form of action research was being employed. Initially, I presented my research proposal as a hermeneutic examination of the facilitators and inhibitors to knowledge sharing in the Western Australia Police. However, somewhere along my research journey I realised that rather than me simply collecting and analysing data from and about my colleagues, …
