Abstract

This paper presents a model for examining the effect of various relationships between mortality rates and lapse rates on the mortality experience of a cohort of insured lives. The approach is individual rather than the aggregate traditionally used in analyzing selective lapsation. The model assumes that insured lives are healthy at policy issue, but later may move to an impaired state from which the lapse rate is zero. Associated with each insured is an unobservable “risk level” random variable, which reflects the heterogeneity of the insured group. Individual mortality and lapse rates are functions of the risk level. A numerical illustration provides some interesting results obtained by using this model.  相似文献

Real estate investment portfolios of financial institutions have seen dramatic changes over the last three decades or more. Historically such property investment decisions have been seen within a portfolio diversification paradigm that has sought to balance risk and return. This paper considers the role of the supply of assets in the determining and constraining the UK institutional portfolio. The supply of real estate assets not only expands during property booms but has also been transformed by a long term urban development cycle as cities adapt to cars and the ICT revolution that has brought new property forms. The research examines long term trends in investment change by disaggregating into ten property forms rather than the usual three land use sectors. It then assesses to what extent investment patterns can be explained in terms of portfolio theory, short term net returns of individual sectors or driven by the supply of real estate assets. It concludes that the supply of real assets is an overlooked explanation.  相似文献

ABSTRACT The popular film Schindler's List is a cinematic portrayal of Oskar Schindler , the German industrialist who rescued more than a thousand of his Jewish workers during the Holocaust . While the film has generated much debate over the character's motivations, the historical Oskar Schindler can be viewed as an economic actor who made several choices. Examined together, these various choices make an excellent case for amenity potential , a concept from the work of Harold Demsetz which explains how one's control over a firm's resources gives one opportunities to use those resources for whatever purposes one sees fit, subject to legal and market constraints . Applying amenity potential to the economic puzzle of Schindler's choices reveals how and why he was able to make various choices which followed the letter of the law in Nazi Society, while violating its spirit.  相似文献

Cognitive skills are robustly associated with good national economic performance. How much of this is due to high-skill countries doing a better job of absorbing total factor productivity from the world's technology leader? Following Benhabib and Spiegel (Handbook of Economic Growth, 2005), who estimated the Nelson–Phelps technology diffusion model, I use the database of IQ tests assembled by Lynn and Vanhanen, 2002, Lynn and Vanhanen, 2006 and find a robust relationship between national average IQ and total factor productivity growth. Controlling for IQ, years of education is of modest statistical significance. If IQ gaps between countries persist and model parameters remain stable, TFP levels are forecasted to sharply diverge, creating a “twin peaks” result. After controlling for IQ, few other growth variables are statistically significant.  相似文献

The objective of this study was to conduct empirical comparisons between two models of optimal experience within an on-site whitewater kayaking setting using a modification of the Experience Sampling Method. Four concerns are examined: (1) differences in explanatory power between the four channel flow model and the Adventure Experience Paradigm, (2) convergent validity among measures used to determine conditions within these models, (3) differences among measures of perceived challenge and risk between test times of Class I-V river difficulty, and (4) differences among measures of perceived skill and competence between test times of Class I-V river difficulty. Questionnaires were administered in the Cheat River Canyon in West Virginia to 52 whitewater kayakers at eight sites of various levels of river difficulty. Data were analyzed at the experience level, rather than between subjects, using 409 experience sampling observations. Hypothesis testing, performed with statistical analyses (stepwise regression, correlations, and repeated measures ANOVA), suggested that the explanatory powers of the four channel flow model and Adventure Experience Paradigm were similar and indicated support for convergent and ecological validity of measures used to determine conditions within each of the two models.  相似文献

Immigrants, both legal and illegal, are a staple of the modern United States workplace. While much of the discussion of this fact centers on negative consequences for the U.S., far less attention has been paid to the detrimental impact on immigrants resulting from their workplace experiences, particularly relating to being targets of discrimination. In this article, we outline: a) a variety of types of workplace discrimination potentially relating to immigrant status; b) potential negative outcomes arising from said discrimination for both immigrant employees and their employers, and; c) how existing and predicted employment law standards place organizations in a legally vulnerable position when such discrimination goes unchecked. We further discuss implications of immigrant-targeted discrimination (ITD) for organizations and managers, and plausible extensions of workplace discrimination laws to specifically include ITD.  相似文献

Companies increasingly seek solutions to the corporate/local dichotomies perceived to be a feature of more traditional approaches to managing across national boundaries. At the human resource level, the rhetoric of transnationalism emphasizes integration being achieved through 'soft' mechanisms, such as corporate culture devices, which encourage all managers to develop an international (for this read corporate) perspective on what they do. In theory, managerial staff are recruited and promoted on a 'best person for the job' basis and national identities are played down. Drawing upon evidence from three international hotel chains (one American, one French and one Swedish), this paper argues that there is a disjuncture between corporate culture devices which assume that they can transcend national origins and the issues of interest and identity which inform the activities and experiences of managers at unit level. The paper suggests that companies need to be aware of the danger of assuming that one can be trained to be 'one of the family'. Rather, we argue that local managers are potentially disadvantaged in terms of career progression as managers from the parent country utilize criteria of acceptability informed by processes of socialization which are more institutionally embedded and derived than has been assumed.  相似文献

The Internet is increasingly used by companies to disseminate financial information. However, the extent to which the use of this new medium will change corporate reporting practice has received surprisingly little debate in the published literature. To widen the participation in the debate, this paper posits that the future of Internet-based financial reporting is contingent on technological and non-technological factors. This proposition is evaluated using the opinions of the immediate trends in online reporting obtained from seventeen UK experts in accounting and/or the Internet who responded to an open-ended questionnaire. These experts were drawn from academics, auditors, regulators, reporting companies and users of corporate reports. While the experts concur on some issues, they provide a range of different views in other areas. Some views are technology-driven, whereas others pay more attention to non-technological factors such as resistance to technological change, users' reluctance to read financial reports and the slow reaction of regulators. Some experts foresee minimum changes in financial reporting over the short term, while others adopt a more progressive or even radical perspective. This paper has synthesized these views into nine major categories which provide information on the role of the Internet in financial reporting. The results have important implications for all parties involved in financial reporting and also indicate avenues for further research.  相似文献
