The purpose of this study was to explore, from readily available data, the best predictors of medical claims costs at Ball State University (BSU). Multiple regression equations were developed to predict BSU's medical claims costs from selected demographic and health-related measures among 1,799 BSU employees. The predictors were chosen from data previously collected during the three-year study period: July 1, 1995 to June 30, 1998. Regression equations were developed for the entire BSU population and the high-cost population. The linear composite of number of emergency room visits, number of chronic health problems, gender and age predicted 17.86% of the variation in transformed medical claims costs for the entire BSU population. The linear composite of age, number of emergency room visits and gender predicted 9.95% of the variation in transformed medical claims costs for high-cost BSU employees. Logistic regression, performed on the entire BSU population, did not differentiate low and highcost employees well: only 15.0% of high-cost employees were classified correctly. / Fisher Institute for Wellness

To accomplish this, we have studied the effect of the claims and temperature anomalies in the opportunities of future investments. We tested a consumption asset pricing model using brazilian time series. Two consumption, two direct insurance claims and four temperature anomalies series were used in these tests. All series belongs to the interval between september 1996 and december 2007, in a quarterly frequency, two years after the beginning of Real plan and one year before the beggining of the credit crisis of 2008. In some cases we used monthly series. We observed positive and significative correlation between direct claims and temperature anomalies. Two models were better than CCAPM. The first with the growth rate of direct claims and the second with the temperature anomalies series elaborated by Goddard Institute of Space Sciences (GISS/NASA). As a result we observed that GISS temperature anomaly series elaborated by GISS is able to affect the future investment opportunities in brazilian capital market / Examinamos a relação entre anomalias de temperatura e séries de sinistros diretos do mercado segurador brasileiro, bem como seu efeito sobre um modelo de precificação de ativos de consumo. Nossa metodologia consistiu na análise da correlação das anomalias de temperatura com a série de sinistros e no efeito dessas séries nas oportunidades futuras de investimento. Testamos um modelo de precificação de ativos de consumo (CCAPM) condicional com as séries temporais brasileiras. Duas séries de consumo, duas séries de sinistros diretos e quatro séries de anomalias de temperatura foram utilizadas na realização dos testes. Todas as séries pertenceram ao período de setembro de 1996 a dezembro de 2007, com freqüência trimestral, dois anos posteriores ao início do plano Real e um ano antes da crise de crédito de 2008. Em alguns casos utilizamos séries mensais. Observamos a existência de correlação positiva e significativa entre as séries de sinistro direto e as anomalias de temperatura. Dois modelos se apresentaram melhores que o CCAPM clássico. O primeiro com a taxa de crescimento da série de sinistros, com pontos que poderíamos considerar como outliers, e o segundo com a série de anomalias de temperatura do hemisfério sul elaborada pelo Goddard Institute of Space Sciences (GISS/NASA). Como resultado observamos que a série de anomalias de temperatura elaborada pelo GISS é capaz de afetar as oportunidades futuras de investimento no mercado de capitais brasileiro.

Thesis (MBA (Business Management))--University of Stellenbosch, 2007. / ENGLISH ABSTRACT: Since its inception in 1998 as a wholly owned captive insurer, Sasguard has successfully supplied the short-term insurance needs of its parent company, Pioneer Foods Pty Ltd. Although the financial results of Sasguard increased steadily over this entire period, the insurer has never investigated the quality of its service regarding the perceptions of its internal support staff, who represent Sasguard to its client Pioneer. The objective of this research report was to critically analyse the insurer’s current risk underwriting and claims management procedures to determine if the current situation was acceptable and if not, to present proposals to reduce costs and to supply Sasguard’s internal clients (members of the parent company) with a better service. The tasks that were completed for this report were: • a literature study on aspects of risk management directly applicable to Sasguard; • critical analysis of the current risk underwriting and claims management procedures; • identification of shortcomings in the current structure; • collection of responses from internal support staff members by an electronic questionnaire; • critical analysis of those responses; and • proposals which Sasguard can implement to address identified shortcomings. The questionnaire was posted on Pioneer’s intranet site, and the entire population of 30 members was notified by email to complete and submit it within a specified period. Twenty-eight staff members did, with two on leave, for a 93% response rate. The responses were analysed in detail to form the basis of the empirical investigation. They were compared to the writer’s own observations, and together were used to develop conclusions and recommendations which Sasguard can implement in future to reduce both risk and costs associated with claims submitted by its internal clients. The main findings follow. Not enough representatives are at management level. Most (89%) want to increase their background knowledge of insurance, mainly through Sasguard. They want a paperless system to view claims. They were divided on whether to establish a workshop to recover parts of disused vehicles; more study is needed. They want to simplify the process of getting quotes and thus facilitating claims. They want better two-way communication. They favoured using the claims history of a branch, along with other forms of reward, to motivate supervisors and drivers, and others, to reduce the accident rate. The issue of whether out-sourced drivers have increased accident claims needs more study. Indeed, the legal employment status of out-sourced drivers needs to be addressed. Most of the internal client representatives were satisfied with the speed of claims settlement, but nearly a third were not entirely satisfied, which the researcher interprets as a cause for concern. Furthermore, one fourth would consider moving to a traditional insurer; this perception also is worrying and can be addressed, possibly through better understanding of the captive insurer and its practices. Proposals followed from the findings, hopefully to be implemented in due course. While results cannot be generalised, they can be provide insight to other captive insurers, especially those in a manufacturing environment similar to that at Pioneer Foods. / AFRIKAANSE OPSOMMING: Vanaf die totstandkoming van Sasguard as ‘n alleenbeheerde gevange versekeraar in 1998, was die maatskappy deurgaans instaat om in sy moeder maatskappy se korttermyn verskeringsbehoeftes te voorsien. Alhoewel Sasguard se finansiële resultate vir die totale periode voortdurend gegroei het, het die versekeraar dit nooit voorheen nodig geag om ‘n ondersoek te loods om te bepaal of dit werklik in sy interne kliënte se verskeringsbehoeftes voorsien het aldan nie. Die oogmerk van hierdie navorsingsverslag was om ‘n kritiese analise op die versekeraar se huidige onderskrywings en eise besturingsmetodes toe te pas om daaruit te bepaal of die huidige metodes wel voldoende is aldan nie. Indien daar bevind sou word dat die huidige metodes nie voldoende is nie, voorstelle te ontwikkel om die koste van eise te verminder en ‘n beter diens aan sy interne kliënte te kan lewer. Die voortvloeinde take van die werkstuk is: • ‘n Literatuurstudie op daardie aspekte van risikobestuur wat ‘n direkte invloed op Sasguard se besigheidsomgewing het; • Kritiese analise van die huidige metodes om risko te onderskryf en eise te bestuur; • Om tekortkominge in die huidige struktuur te identifiseer; • Verkryging van die versekeraar se interne ondersteuningspersoneel se opinies deur ‘n elektroniese vraelys; • ‘n Kritiese analise van die respondente se antwoorde; en • Voorstelle wat Sasguard kan gebruik om die geidentifiseerde tekortkominge suksesvol aan te spreek. Die vraelys was op die maatskappy se intranet netwerk geplaas en e-posse is gebruik om elke individuele respondent in kennis te stel om die vraelys te voltooi binne ‘n bepaalde tydperk. ‘n Totaal van 28 uit die 30 populasie het die vraelys voltooi, vir ‘n totale reaksie van 93 persent. Die antwoorde vanaf respondente is getabuleer en het gedien as basis van die empiriese studie. Deur die getabuleerde data met die skrywer se eie observasies te vergelyk kon voorstelle ontwerp word wat die versekeraar in die toekoms kan gebruik om aan die een kant sy blootstelling aan risiko te verminder en aan die ander kant sy eisekoste te verlaag. Die hoofbevindinge van die studie volg hiernaas. ‘n Grooter aantal interne kliënt verteenwoordigers moet op bestuursvlak dien by die interne kliënt. Die meeste van hierdie verteenwoordigers het ‘n behoefte daaraan om hulle verskeringskennis uit te brei, hulle verkies ‘n papierlose sisteem waarop vordering van hulle ingediende eise vertoon word, hulle het ‘n behoefte aan ‘n meer eenvoudige proses om kwotasies te verkry en hulle benodig verbeterde tweerigting kommunikasie. Hulle is optimisties dat aksies waardeur goeie drywers erkenning ontvang ‘n positiewe invloed kan hê op hierdie drywers, asook ander individue, wat daardeur ook toekomstige eise sal verlaag. Die terugvoer was dubbelsinnig rakende die oprigting van ‘n sentrale onderdele verskaffer, die ongeluksratio van uitgekontrakteerde drywers, sowel as die wetlike aspekte rondom die status van hierdie drywers. Areas van kommer is die ontevredenheid van sommige interne verteenwoordigers ten opsigte van die spoed van eise afhandeling, asook die siening dat tradisionele versekering moontlik meer waarde kan bied as gevange versekering. Alhoewel die resultate van hierdie navorsingsprojek nie veralgemeen kan word nie, voorsien dit wel insig aan ander gevange versekeraars, veral vir organisasies wat in dieselfde vervaardigings-sektor as Pioneer Foods sake doen.

Flooding is a global challenge that has plagued mankind throughout history, affecting over 164 million people worldwide in 2007 alone. As the frequency of flooding increases in England and Wales coupled with an increase in the number of properties at risk of flooding and the attendant huge (insured) economic costs of flooding, the services received by homeowners during flood damage repair works, have not been spared criticism, Both the Welsh Consumer Council report and the Warwickshire Trading Standards report raised serious questions about the level of service in insurance claims for the repair of flood-damaged domestic property. This research project was therefore aimed at investigating the level of service quality and determinants of homeowners’ satisfaction in England and Wales with respect to flood damage repair works during insurance claims. A comprehensive literature review was conducted on customers’ needs, satisfaction and service quality, flooding and related issues, and the repair of flood damaged domestic property, in order to set the framework for the research and shape the development of the research questions/hypotheses. The study employed a two-phased sequential mixed methods approach, commencing with 20 in-depth interviews with homeowners, repairers, insurers and loss adjusters. Findings from the initial exploratory study (and from the literature review) informed the development of a questionnaire instrument, which incorporated elements of SERVQUAL, the generic service quality measurement instrument. Survey data were collected for the quantitative phase of the study from a sample of 126 homeowners, which was then analysed to test the hypotheses put forward in the study. The data did not yield a set of reliable and interpretable factors of service quality from the three service quality scales used to measure homeowners’ perceptions of the performance of insurers, loss adjusters and contractors. However, of the three key service providers, the contractor’s performance was the best predictor of homeowners’ overall satisfaction during flood damage reinstatement claims, accounting for seven times the combined unique contribution of insurance and loss adjusting firms. In addition, satisfaction levels were significantly different for homeowners whose claims for repair works were completed within six months compared to those repairs exceeded twelve months. The thesis concludes with implications of the findings for practice as well as recommendations for further research. It is argued that knowledge of the determinants of homeowners’ satisfaction with services during the repair of flood damaged property, is beneficial not only to insurers, loss adjusters and repairers but to homeowners as well.
