Violations of Service Fairness and Legal Ramifications: The Case of the Managed Care Industry

Adapted from Chan's (2000) model depicting success of litigation, this paper argues that with the application of various legislation, health maintenance organizations' (HMOs') violations of service fairness to each group: enrollees, physicians, and hospitals give rise to each group's lawsuits against the HMOs. Various authors (Bowen et al., 1999; Seiders and Berry, 1998) indicate that justice concepts such as distributive, procedural, and interactional justice can be applied to the area of service fairness. The violation of these underlying justice principles with HMOs' service unfairness to enrollees, physicians, and hospitals is examined. A general synopsis of the ethical issues in the managed care industry is provided. The various lawsuits launched by each group: enrollees, physicians, and hospitals together with the key statutes used are discussed. This paper also highlights the provisions and ramifications of the 11 April 2000 landmark agreement that Aetna made with Texas Attorney General John Cornyn to settle the 1998 lawsuit brought against the company. Lastly, the current ethical issues in the managed care industry are further discussed. The value of this paper can be adapted to the study of organizations' service fairness violations in other industries or in the educational, governmental, and not-for-profit sectors both nationally and internationally.     

Price-volume relation in stocks: A multiple time series analysis on the Singapore market

We examine the price-volume relation in stocks using the multiple time series approach due to Tiao and Box (1981). This approach has the advantage of treating price and volume jointly and symmetrically (without enforcing the roles of input and output). It is free of the simultaneity bias in regression analysis and the unidirectional dynamics imposed by transfer function models. Empirical results show that there is implicit positive correlation between price and volume through their residuals. However, the results for the explicit lead and lag relations are mixed. The technical analysts' adage that volume often leads the trend of price is not supported. Nonetheless, the implicit relationship between price and volume confirms the usefulness of incorporating volume data to forecast future return. Our analysis shows that the multiple time series models outperform the univariate models in post-sample forecasts.     

From T-Bills to Stocks: Seasonal Anomalies Revisited

This paper employed eleven data series which consist of stocks, bonds, bills, equity premiums, term premiums, and various default premiums to investigate whether January seasonality reported in existing literature is robust across different states of the economy as this has important trading implications. For the periods 1926–1990, small stocks, small stock premiums, low grade bonds, and default premiums (spread between high grade, low grade and government bonds) reveal January seasonality and that the seasonality is robust across different states of the economy except for low grade bond returns and default premiums. January seasonality for low grade bond returns and low grade bond default premiums are primarily driven by results found during periods of economic expansion. Overall, January seasonality is more evident during the economic expansion periods although the magnitude of default premiums is larger during periods of economic contraction. Furthermore, prior findings of strong summer equity returns are primarily driven by the results found during the periods of economic contraction. It is also found that equity returns are generally higher during periods of economic expansion.     

Strategic profiles and performance: An empirical test of select key propositions

Competing theories on internal orientation versus external orientation are examined. The relevant theories are amalgamated and condensed into a number of competing propositions that are empirically tested. The findings suggest that the internally oriented businesses as well as the externally oriented businesses underperform the efficient, marketing oriented businesses.     

Minnesota-type adaptive hierarchical priors for large Bayesian VARs

Large Bayesian VARs with stochastic volatility are increasingly used in empirical macroeconomics. The key to making these highly parameterized VARs useful is the use of shrinkage priors. We develop a family of priors that captures the best features of two prominent classes of shrinkage priors: adaptive hierarchical priors and Minnesota priors. Like adaptive hierarchical priors, these new priors ensure that only ‘small’ coefficients are strongly shrunk to zero, while ‘large’ coefficients remain intact. At the same time, these new priors can also incorporate many useful features of the Minnesota priors such as cross-variable shrinkage and shrinking coefficients on higher lags more aggressively. We introduce a fast posterior sampler to estimate BVARs with this family of priors—for a BVAR with 25 variables and 4 lags, obtaining 10,000 posterior draws takes about 3 min on a standard desktop computer. In a forecasting exercise, we show that these new priors outperform both adaptive hierarchical priors and Minnesota priors.     

Debt and Equity Characteristics of Mandatorily Redeemable Preferred Stock

Abstract. This study examines whether mandatorily redeemable preferred stock (MRPS) is priced more like debt or equity by (1) investigating its debt and equity characteristics and (2) specifying conditions under which one characteristic would dominate the other. Based on a sample of 113 nonconvertible MRPS issued during 1970 to 1990, our results are consistent with the view that MRPS has both debt and equity characteristics. The debt (equity) feature is more pronounced among nonutility (utility) issues. Within the utility group, we find high (low) rated MRPS issues to be more debt (equity) like. Our results appear to support current MRPS disclosure rules.     

土地整治功能分区及其整治方向研究

[目的]土地整治的目标开始由注重"新增耕地"向注重"区域功能"转变,土地整治内涵由此得到延伸。同时,也迫切需要推进以提升区域功能为导向的土地整治分区研究。[方法]文章针对我国土地整治分区管理的需求,基于我国地理环境的背景差异及地域功能的定位、土地整治内涵的演变,运用要素加权叠加法、空间聚类分析法和专家经验判断法与区划对比分析法等开展土地整治功能分区。[结果]该文构建并提出了以功能导向为核心的土地整治分区体系和方案,将我国土地整治按地域功能划分为:(1)以生态修复、保护和建设为主的生态功能保育区,(2)以基本农田建设、农地开发整理、提高区域耕地的生产能力为主的粮食安全保障功能区,(3)以城乡用地统筹整治、城市用地内部挖掘为主的经济发展支持功能区,(4)以划定保护区、保护性建设为主的景观文化维护功能区等4种类型区,进一步结合东北平原区、华北平原区、黄土高原区等12个地理空间单元,组合为61个土地整治功能一级分区。在此基础上,评价一级功能区内各县域单元土地整治功能,识别出景观文化维护功能、粮食安全保障功能、生态建设功能、生态保护功能、城镇发展优化功能和城镇发展集聚功能,续分土地整治功能二级分区即各县域的土地整治功能。[结论]基于功能导向的土地整治分区反映了区域功能及其关系对土地整治分区的引导作用,为分区管控和引导提供了科学依据,这对提升区域功能和加强土地利用功能的联系和互动起到重要的作用。     

Assimilation of Hong Kong Immigrants in Canada

A flood of emigration from Hong Kong to Canada was observed prior to the handover from Britain back to China in 1997. I pool Canadian Census data from 1991 to 2006 to study the labour market assimilation of Hong Kong immigrants. The findings suggest that these immigrants faced a significant negative wage gap upon entry in comparison with Canadian‐born individuals, and this was larger for cohorts arriving closer to 1997, suggesting a decline in cohort quality. The results also indicate that earnings convergence with the Canadian‐born was slow for the majority of these immigrants.     

Value Orientations, Income and Displacement Effects, and Voluntary Contributions

Identifying the value orientations of subjects participating in market or non-market decisions by having them participate in a ring game may be helpful in understanding the behaviour of these subjects. This experiment presents the results of changes in the centre and the radius of a value orientations ring in an attempt to discover if the measured value orientations exhibit income or displacement effects. Neither significant income effects nor displacement effects are identified. An external validity check with a voluntary contribution game provides evidence that value orientations from rings centred around the origin of the decision-space explain significant portions of voluntary contributions while value orientations from displaced rings do not.     

An Empirical Analysis of Synthesizing the Effects of Festival Quality,Emotion, Festival Image and Festival Satisfaction on Festival Loyalty: A Case Study of Macau Food Festival

This study aims to examine the interrelationships among the festival quality dimensions, festival quality, emotion, festival image, festival satisfaction and festival loyalty. Analysis of data from 454 attendees in the 12^th Macau Food Festival indicates that the proposed model fits the data. The result of this study will assist festival management in developing and implementing market‐orientated service strategies to increase quality and image, and enhance the emotion and satisfaction of attendees in order to attain their loyalty toward food festivals.
