This paper presents an inventory problem related to the one-period stochastic inventory (or “newsboy”) problem. In this problem, the firm has to decide how much product to order to meet a random one-period demand. The version of the problem presented is novel in two respects. First, demand is explicitly permitted to be negative, and second, the penalty (or shortage) cost is assumed to be independent of the magnitude of the shortage. This situation is shown to change the form of the cost function and to complicate the determination of optimal policies. The form of the optimal policy is developed, and two example problems are presented in some detail. 相似文献

This paper addresses the questions of market penetration and locational conflict in a franchise system of distribution. The models developed provide a means to evaluate alternative scenarios and the effects of various franchise policies. It is shown that the market penetration and location goals of the members of a franchise system coincide only under a very limited set of circumstances. 相似文献

While it is well known that the widowed suffer increased mortality risks, the mechanism of this survival disadvantage is still
under investigation. In this article, we examine the quality of health care as a possible link between widowhood and mortality
using a unique data set of 475,313 elderly couples who were followed up for up to nine years. We address whether the transition
to widowhood affects the quality of care that individuals receive and explore the extent to which these changes mediate the
elevated mortality hazard for the widowed. We analyze six established measures of quality of health care in a fixed-effect
framework to account for unobserved heterogeneity. Caregiving and acute bereavement during the transition to widowhood appear
to distract individuals from taking care of their own health care needs in the short run. However, being widowed does not
have long-term detrimental effects on individuals’ ability to sustain contact with the formal medical system. Moreover, the
short-run disruption does not mediate the widowhood effect on mortality. Nevertheless, long after spousal death, men suffer
from a decline in the quality of informal care, coordination between formal and informal care, and the ability to advocate
and communicate in formal medical settings. These findings illustrate women’s centrality in the household production of health
and identify important points of intervention in optimizing men’s adjustment to widowhood. 相似文献

In this study, I examine disparities in schooling progress among children born to immigrant and U.S.-born blacks. I find that
in one- and two-parent families, children born to black immigrants are less likely to fall behind in school than those born
to U.S.-born blacks. In two-parent immigrant families, children born to two immigrant parents have a significant schooling
advantage over children born to one immigrant parent. While children born to two immigrant parents in the wealthiest black
immigrant families do better in the second generation than in the first, the reverse is observed among children in less wealthy
families. These findings contribute in two ways to our understanding of the assimilation processes of children born to black
immigrant parents. First, they show that there is a positive association between the number of immigrant parents in a family
and children’s schooling performance. Second, they suggest that disparities in the assimilation patterns of the children of
black immigrants are a likely product of the interaction between their parental characteristics and the socioeconomic circumstances
of their families. 相似文献

Determining priority importance is a matter of concerns among the organization to improve their performance. One of the important
aspects that should be considered by the organization is management of human resources, comprising of members who have their
own family life. In this paper, we deliver a new perspective for organization to provide priority importance for their members
with respect to family matters in order to inculcate the sense of belonging in the organization. To be effective in considering
family matters in the organizational policy making, closer look of family characteristics are required. The idea of translating
several family characteristics as quality variables and applying the quality function deployment (QFD) method to these variables
could present a new way of improving the decision making in the organization by considering the process of decision in the
family. Quality function deployment for family (QFDF) produces a friendly interpretation of a highly complex and intangible
matters around family life; thus, making the assessment of a family easier. QFD is applied on the data gathered from a questionnaire
survey based on 1,213 families in West Malaysia, Malaysia. Twelve variables are identified as voice of family, where seven
of them are found to have the highest priority of importance. These variables could also be translated into quality variables
in the context of organization, the strategy of improvement for the family could be interpreted as strategy for improvement
in the organization. Furthermore, the results of this study provide suggestion to improve actions for managing human resource.
In the discussion, three most high ranked variables from both perspectives of family and organization are considered. 相似文献

中国农村最低生活保障标准研究 总被引:11,自引:0,他引:11
随着经济的发展,国家扶贫力度的加大,中国贫困人口分布呈现出分散分布的格局。新时期扶贫的思路转变为将农村贫困人口纳入最低生活保障制度范畴。东部沿海经济发展较好的城市已逐步在建立农村最低生活保障制度。农村最低生活保障制度的建立为缓解农村贫困提供了美好的蓝图,但有许多问题需要解决。其中,最低生活保障的标准怎么制定是一个关键问题,也是国际社会比较关注的焦点。本文拟就在新世纪提高农村扶贫标准政策下制定农村最低生活保障标准的相关问题进行探讨。 相似文献

This paper examines the impact of relative income on income satisfaction with given absolute income. We conducted an experiment in China where participants earned three different levels of income according to their relative performance in a task. While the treatment group was informed about their relative income, the control group only knew their own absolute income. We found that while controlling for absolute income and other factors, information about relative income increases the satisfaction of the high-income group and reduces the satisfaction of the low-income group. Relative income may interact with individual characteristics, such as gender, to affect income satisfaction. We also found that relative income treatment significantly increases income satisfaction inequality, primarily by causing social comparisons among different income groups, which has some welfare implications. 相似文献
