Anova and minque type of estimators for the one-way random effects model

The one-way random effects model with unequal variances and unequal sample sizes is considered. Estimation of the variances, variance of a single observation (total variance), and the standard error of the unweighted mean are considered. Precision of the Analysis of Variance and Unweighted Sums of Squares type of estimators and the Minimum Norm Quadratic Unbiased Estimators with a priori weights are examined.     

On some analogues of lack of memory properties for the Gompertz distribution

We discuss some analogues of the lack of memory property, the strong lack of memory property and the almost lack of memory properties for the Gompertz distribution as applications of the integrated Cauchy functional equation.     

经济转型时期“用工荒”现象及其成因的经济学分析

文章从技能型劳动者的分类界定入手,对不同类型劳动者所面临的"用工荒"现象及其成因机制进行微观视角的分类研究。结果发现,当前的"用工荒"现象包含了多种类型的劳动者短缺,其中非技能型劳动者短缺的主要原因是被扭曲的收入分配比例和无保障的弹性用工模式导致新生代农民工供给激励不足,随着企业转型升级进程加快,此类"用工荒"现象将得到有效缓解;而造成技能型劳动者短缺的原因,既包括经济转型发展使对技能型劳动者的需求结构性增长,也有基于历史和现实原因的劳动者供给数量不足。技能型劳动者培育过程中的劳资双方行为"协调失灵"、政府职能缺位、社会化培训体系建设滞后和劳动力市场的无序发展等因素都是导致技能型劳动者增长速度滞后于经济转型发展要求、进而导致技能型劳动者"用工荒"现象的主要原因。

A note on the strategic aspects of the transfer paradox

It is well known that an agent can be hurt by accepting a gift, the donor of which is made better off. Why then does the recipient accept this welfare reducing gift? This paper examines the strategic aspects of the paradox. It shows that if the recipient refuses the gift, it would suffer an even greater loss of welfare since there is a mutually advantageous reallocation between the donor and a third agent. It is shown that the recipient does have a viable alternative strategy: it could destroy some of its endowment, raising its welfare level and reducing that of the potential donor.     

Managerial value and belief systems in a cross-national context: The case of thetrivial significance

This article discusses potential theoretical and methodological flaws in value-based research in a cross-national context. Using data from a comparative study of American and Indian CEOs, it is shown that some managerial beliefs and value systems do vary as a function of national background. While this is neither surprising nor exciting, whether this significantheterogeneity offers nontrivial predictive utilityin explaining the observed variance in a large number of structural, strategic, and other critical variables at the organizational level is the more important question. This study offers preliminary evidence to the contrary.In this era of multinational corporations and an emerging global market for executive and managerial talent, the question of whether some managerial beliefs and value systems persist in spite of extensive acculturation and socialization has been an issue of concern — especially in the United States because of a large and continuing flow of immigrants. Our results show in essence that this question, though important and interesting from a sociological angle, is perhaps not as crucial as one might suppose in influencing the strategic thrust, structural configurations, or certain aspects of performance of an organization.     

THE EFFECT OF POSTPONABLE INTERRUPTIONS ON A M/G/1 SYSTEM WITH IMPATIENT CUSTOMERS

This paper considers a waiting line system where units become impatient after having waited for certain time and leave the queue (renege) without being serviced. The servicing of the units is subject to interruption by the arrival of an "interruption " possessing a priority for service over the ordinary units, head-of-the-line priority discipline being prevalent. The busy period process is investigated first, making use of the supplementary variable method. Later, the general process is studied in terms of the busy period process and renewal distributions. Lastly, the ergodic properties of the general process are examined by appealing to some results of renewal theory.
