The prior literature has identified a number of variables that can be used to determine hospital quality, but methodologies for combining variables into an overall measure of hospital quality are not well developed. This analysis builds on the prior investigation of hospital quality by evaluating a method originally developed for the detection of health-care fraud, Pridit, in the context of determining hospital quality. We developed a theoretical model to justify the application of Pridit to the hospital quality setting and then applied the Pridit method to a national, multiyear data set on U.S. hospital quality variables and outcomes. The results demonstrate how the Pridit method can be used predictively, in order to predict future health outcomes based on currently available quality measures. These results inform the use of Pridit, and other unsupervised learning methods, in fraud detection and other settings where valid and reliable outcomes variables are difficult to obtain. The empirical results obtained in this study may also be of use to health insurers and policymakers who aim to improve quality in the hospital setting.","PeriodicalId":192218,"journal":{"name":"Wiley-Blackwell: Risk Management & Insurance Review","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125054041","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We present a longitudinal analysis of student feedback, reflecting results from one survey administered before the camp began and another distributed very near the camp's end. Our results indicate the camp succeeded on many counts.","PeriodicalId":192218,"journal":{"name":"Wiley-Blackwell: Risk Management & Insurance Review","volume":"78 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114847532","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Huston","doi":"10.1111/rmir.12031","DOIUrl":"https://doi.org/10.1111/rmir.12031","url":null,"abstract":"Life insurance is a tool that households use to hedge against the uncertainty of labor income flows over the life cycle and to meet bequest motives. While overall demand for life insurance continues a 50-year downward trend, term life insurance has gained in popularity over cash value insurance in the last 18 years. The popular press and some literature about life insurance demand suggest the change in demand is mainly driven by changing demographics, shifting life insurance marketing efforts, and changes in timing of family formation. This paper attempts to identify exogenous factors influencing the demand for cash value life insurance beyond the demographic factors and changing marketing efforts. Using the 1992 through 2010 SCFs and logistic regression, we find that the introduction of tax-advantaged retirement and education savings plans in the late 1990s is reducing the need for cash value life insurance. We find increased demand for cash value life insurance for households vulnerable to estate taxes after 2001 despite increased estate tax exemptions. We also find evidence that more highly financially sophisticated households are more likely to own the more sophisticated cash value life insurance products.","PeriodicalId":192218,"journal":{"name":"Wiley-Blackwell: Risk Management & Insurance Review","volume":"23 3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-08-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123661343","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Though there have been discussions among insurers, organizations, and academics as to how to address this issue, until recently, each group has been primarily working in isolation. The Insurance Education & Career Summit, which took place in September 2011, brought together 110 individuals across these groups for the purpose of creating a unified strategy to both attract and retain skilled workers to the insurance industry and work to create the next generation of insurance executives. This article provides a brief background on the talent gap issue. We also discuss its potential impact on the insurance industry. Finally, we summarize the main obstacles identified by Summit participants to both attracting and retaining skilled workers as well as the strategies developed to overcome these obstacles.","PeriodicalId":192218,"journal":{"name":"Wiley-Blackwell: Risk Management & Insurance Review","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125464987","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In view of the specific features of the Italian market for complementary insurance (relatively young and less developed), these empirical results might be of interest to policymakers acting in countries with similar features (for instance, some of the more recent EU members).","PeriodicalId":192218,"journal":{"name":"Wiley-Blackwell: Risk Management & Insurance Review","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116480814","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We find significant but differing impacts of these explanatory variables on the extracted components. For example, equity volatility seems to have a larger influence on the transitory component, suggesting that its effect may be mostly short-lived, while our proxy for illiquidity has a greater impact on the persistent component indicating its more enduring effect. Also, the slope of the yield curve has impacts with opposite signs on the two components and so our analysis thus helps address the conflicting results reported in earlier studies without such a component framework. These results indicate that a two-factor formulation may be needed to model CDS options.","PeriodicalId":192218,"journal":{"name":"Wiley-Blackwell: Risk Management & Insurance Review","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-09-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131145615","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Specifically, this teaching note provides step‐by‐step instruction for simulating the present value of payments for losses occurring within a 1‐year policy period.
