Using Multiple Methods In Personality Psychology, Brent W. Roberts, Peter D. Harms, Jennifer L. Smith, Dustin Wood, Michelle Webb

Leadership Institute: Faculty Publications

In many ways, Campbell and Fiske’s (1959) article on multitrait-multimethod (MTMM) approaches to construct validity has stood like a Platonic ideal for personality psychologists since its publication. In the ideal study, and scientific world, our constructs should converge in a robust and coherent fashion across diverse methods. Moreover, we should all aspire to use multiple methods in both validating our measures and in investigating our ideas. Interestingly, that Platonic ideal is not realized as often as expected. If one looks closely at the empirical literature in personality psychology, the expectation that abstract constructs should converge across methods is seldom met …

A Note On The Instability Of The Unprojected Individual Level Premium Cost Method, Pierre Devolder, Valerie Goffin

Journal of Actuarial Practice (1993–2006)

We compare the unit credit and the unprojected individual level premium cost methods in a continuous time environment and show that the latter may produce unstable contribution rates in a dynamic environment. Specifically, assuming there are no unfunded liabilities, we prove that the unprojected individual premium cost method may produce non-bounded contributions if benefits change too close to the normal retirement age.

Solvency Of Life Insurance Companies: Methodological Issues, Rosa Cocozza, Emilia Di Lorenzo

Journal of Actuarial Practice (1993–2006)

The paper deals with solvency assessment for life insurance business; some methodological issues concerning the solvency of life insurance companies, particularly connected to the investment risk, are suggested. Considerations about the technical equilibrium of an insurance portfolio and the financial regulation lead to a dynamic system involving risk measure and solvency assessment. The formal model is applied to a life annuity cohort in a stochastic context in order to exemplify the potential of the model, especially referred to the need to frame solvency assessment in a dynamic perspective.

Bayesian Analysis Of A Health Insurance Model, Helio S. Migon, Edison M.O. Penna

Journal of Actuarial Practice (1993–2006)

We consider the problem of determining health insurance premiums based on past information on size of loss, number of losses, and size of population at risk. The size of loss and the number of losses are treated as mutually independent random variables. The number of losses is assumed to follow a Poisson process, and the loss sizes are independent and identically distributed non-negative random variables, and the population at risk is assumed to follow a non-linear growth model. An expression for the premium is obtained through maximization of the insurer's expected utility under a Bayesian model. The parameter estimation process …

Pricing Insurance Policies With A Distribution-Free Financial Pricing Model, Min-Ming Wen

Journal of Actuarial Practice (1993–2006)

The highly skewed and heavy tailed distributions used to model insurance losses (claims) raise a concern about the validity of the applications of the capital asset pricing model (CAPM) to insurance pricing when market risks are essential. This paper provides an alternative pricing model, called the Rubinstein-Leland model, which can be used to price insurance contracts. The Rubinstein-Leland model has a distribution-free feature that can fully capture the asymmetry embedded in insurance losses. Thus, this model is better able to derive fair prices for insurance policies than is the CAPM.

Bivariate Archimedean Copula Models For Censored Data In Non-Life Insurance, Michel Denuit, Oana Purcaru, Ingrid Van Keilegom

Journal of Actuarial Practice (1993–2006)

We describe a methodology based on Archimedean copulas for analyzing nonlife insurance data with censoring present. Specifically, we propose a graphical selection procedure for the nonparametric estimation of the generator. An actual loss-ALAE data set is used for the numerical illustrations and for comparisons of our approach to a few others.

Consistent Assumptions For Modeling Credit Loss Correlations, Jan Dhaene, Marc J. Goovaerts, Robert Koch, Ruben Olieslagers, Olivier Romijn, Steven Vanduffel

Journal of Actuarial Practice (1993–2006)

We consider a single period portfolio of n dependent credit risks that are subject to default during the period. We show that using stochastic loss given default random variables in conjunction with default correlations can give rise to an inconsistent set of assumptions for estimating the variance of the portfolio loss. Two sets of consistent assumptions are provided, which it turns out, also provide bounds on the variance of the portfolio's loss. An example of an inconsistent set of assumptions is given.

Simplified Data Analytics For The Accurate Evaluation Of A New Venture’S Market Potential, Michael D. Mattei, Stephen Hellebusch

New England Journal of Entrepreneurship

This article examines the creation of an accurate market projection designed with easy-to-use, cost-effective data analytic techniques. Many of the techniques explored are derived from the subdisciplines of decision support and data warehousing found in the information technology arena. Two significant contributions are presented: a simple mathematical technique that eliminates the need for heuristics, and the simplification of the process to the point where no computer or sophisticated statistical analysis is needed.

The Impact Of Efficacy On Work Attitudes Across Cultures, Fred Luthans, Weichun Zhu, Bruce Avolio

Department of Management: Faculty Publications

To answer the call for more cross-cultural research, this study analyzed the efficacy and work attitudes of employee samples from the U.S. and Southeast Asia (Indonesia, Malaysia, and Thailand). The results showed that across these two samples, general efficacy had a significant positive relationship with organizational commitment and a significant negative relationship with intention to turnover. Further analysis also indicated that job satisfaction mediated the relationship between general efficacy and organizational commitment and intention to quit in the U.S. sample. The relationship between general efficacy and organizational commitment was stronger in the U.S. than in the three combined countries sampled …

The Business Dynamics In Telecommunication Market Consolidation, George Amstad

LSU Master's Theses

The Swiss telecommunication market is quite different from the markets in surrounding European countries. The Swiss Market is characterized by a very small number of competitors and relatively high and stable prices. The model in this thesis explains shows how the limited competition enables the mobile telecommunication service providers to keep prices up. This is due to a oligopoly market situation linked to complicated laws that discourage new competitors to join the Swiss market. Later in 2006, the Swiss federal council will pass the new televisor law, which will make it significantly easier to join the Swiss market. This will …

Is Support For Strategic Flexibility, Environmental Dynamism, And Firm Performance, Michael J. Zhang

WCBT Faculty Publications

Increasingly, strategic flexibility has been viewed as a critical organizational competency that enables firms to achieve and maintain competitive advantage and superior performance. In this study, the relationship between IS support for strategic flexibility and the bottom-line performance of firms is investigated, as well as the moderating effects of environmental dynamism on that relationship. Using both survey and archival data, IS support for strategic flexibility was positively associated with profitability and labor productivity only when there was a high degree of environmental changes and uncertainty.

An Exploration Of Theories Of Action In Leadership Development: A Case Study, Scott J. Allen

Antioch University Dissertations & Theses

The central purpose of the present study was to examine how academic notions of leadership development compare and contrast with the theory of action that guides corporate leadership development initiatives. A secondary purpose was to analyze the process and potential extensions of the user-focused theory of action approach. Initial findings suggest that the user-focused theory of action approach is transferable to the case studied. In addition, an analysis of the leadership development literature and the Frontline Leadership Excellence System yielded a thought-provoking comparison of theory and practice. The study also provided an analysis of literature gaps and useful suggestions regarding …

Bar Raising Or Navel-Gazing?:The Effectiveness Of Self-Study Programmes In Eading To Improvements In Institutional Performance, Deirdre Lillis

Conference papers

Higher Education Institutes worldwide are investing significant resources in self study programmes to improve institutional performance, to enhance quality and to meet external stakeholder demands. The institutional impacts of both internally and externally mandated self study programmes is an area where little empirical research exists. A key question is whether self study programmes are effective (or otherwise) in leading to improvements in institutional performance and the reasons why. Covering an eight year period, from 1997–2006, this paper reports on the use of systematic evaluation methodology (Rossi et al., 2003) to evaluate the effectiveness of three self study programmes in leading …

Estimation Of Large Insurance Losses: A Case Study, Tine Buch-Kromann

Journal of Actuarial Practice (1993–2006)

This paper demonstrates an approach to analyzing liability data recently developed by a Danish insurance company. The approach is based on a Champernowne distribution, which is corrected with a non-parametric estimator. The correction estimator is obtained by transforming the data set with the estimated modified Champernowne cdf and then estimating the density of the transformed data set by using the classical kernel density estimator. Our approach is illustrated by applying it to an actual data set.

On Some Risk-Adjusted Tail-Based Premium Calculation Principles, Edward Furman, Zinoviy Landsman

Journal of Actuarial Practice (1993–2006)

This paper explores two tail-based premium calculation principles, the tail standard deviation (TSD) premium and the tail conditional expectation (TCE) premium, in their risk-adjusted and unadjusted forms. They are risk-adjusted using so-called distortion functions. We prove that the proportional hazard (PH) risk-adjusted TCE premium is larger than the unadjusted TCE premium. Additionally, given a risk distribution with location and scale parameters, we prove that the PH risk-adjusted TCE premium reduces to the unadjusted TSD premium.

Spatial Distribution Of Frequency And Severity Of Water Claims In California, Gurbhag Singh, Max Tang, Don Mcneill, Lyn Hunstad

Journal of Actuarial Practice (1993–2006)

We examine the frequency and severity of water loss claims for homeowners insurance across the state of California for the experience years 2000, 2001, and 2002. The spatial distribution patterns of frequencies and severities are mapped and analyzed at the zip code level. The maps reveal the pockets of high frequencies and severities. The information provided in this paper will assist actuaries and policy makers in their quest to set accurate rates for homeowners insurance.

Bayesian Analysis Of Insurance Losses Using The Buhlmann-Straub Credibility Model, Abraham J. Van Der Merwe, Kobus N. Bekker

Journal of Actuarial Practice (1993–2006)

We propose a Bayesian analysis to develop credibility estimates of the well known Biihlmann-Straub model. We describe simple numerical methods to obtain exact posterior distributions and predictive densities under this model. These distributions are obtained through Monte Carlo simulations that generate independent samples from the joint posterior distribution. Our methods are therefore preferable to methods such as Gibbs sampling, which generates dependent samples from the joint distribution. The methods discussed also can be extended to more complicated credibility models.

Analysis Of An Insurance Risk Model With Thinning Dependence And Common Shock, Lai Mei Wan, Kam Chuen Yuen, Wai Keung Li

Journal of Actuarial Practice (1993–2006)

We consider a continuous-time insurance risk model with m dependent classes of business with dependent claim number processes due to thinning dependence and a common shock. The impact of the dependence is studied via the adjustment coefficient. The case m = 2 is investigated analytically for exponential claim distributions and via simulation for non-exponential claim distributions.

The Importance Of Vertical And Shared Leadership Within New Venture Top Management Teams: Implications For The Performance Of Startups, Michael D. Ensley, Keith M. Hmieleski, Craig L. Pearce

Department of Management: Faculty Publications

The current study investigated the relative influence of vertical versus shared leadership within new venture top management teams on the performance of startups using two different samples. Vertical leadership stems from an appointed or formal leader of a team (e.g., the CEO), whereas shared leadership is a form of distributed leadership stemming from within a team. Transformational, transactional, empowering, and directive dimensions of both vertical and shared leadership were examined. New venture performance was considered in terms of revenue growth and employee growth. The first sample was comprised of 66 top management teams of firms drawn from Inc. Magazine’s …

Virtuous Leadership: A Theoretical Model And Research Agenda, Craig L. Pearce, David A. Waldman, Mihaly Csikszentmihalyi

Department of Management: Faculty Publications

In this manuscript we attempt to shed light on the concept of virtuous leadership. We first attempt to identify the nature of virtuous leadership. Next, we specify two potential antecedents of virtuous vertical leadership. Specifically, we identify the personal characteristic of responsibility disposition as well as environmental cues as potential predictors of subsequent virtuous leadership. Moreover. we articulate how virtuous vertical leadership might result in virtuous shared leadership. We also demonstrate how both vertical and shared virtuous leadership can act as key factors in the creation of organizational learning. Importantly. we specify several important research implications of our theoretical model. …

Potential Added Value Of Psychological Capital In Predicting Work Attitudes, Milan Larson, Fred Luthans

Department of Management: Faculty Publications

Meeting the challenge of effectively managing human resources requires new thinking and approaches. To extend the traditional perspective of economic capital, increasing recognition is being given to human capital and more recently social capital, this article proposes and empirically tests the potential added value that psychological capital may have for employee attitudes of satisfaction and commitment. After first providing the background and theory of PsyCap, this article reports a study of manufacturing employees (N = 74) that found a significant relationship between PsyCap and job satisfaction (r=.373) and organization commitment (r=.313). Importantly, the employees’ PsyCap had a significant added impact …

Developing The Psychological Capital Of Resiliency, Fred Luthans, Gretchen R Vogelgesang, Paul B. Lester

Department of Management: Faculty Publications

In these turbulent times, we propose the importance of developing the psychological capital dimension of resiliency. After providing the theoretical background and meaning of psychological capital in general and resiliency in particular, the authors present proactive and reactive human resource development (HRD) strategies for its development. The proactive HRD includes increasing psychological assets, decreasing risk factors, and facilitating processes that allow human resources to enhance their resilience. The reactive HRD largely draws from a broaden-and-build model of positive emotions and self-enhancement, external attribution, and hardiness. The article includes specific guidelines for HRD applications and an agenda for future needed research.
