Improving perishable product inventory management using goal programming

The multiple objectives of perishable product inventory management are examined in this paper. These objectives include: (1) satisfying demand by carrying sufficient inventories, (2) holding down inventory carrying costs, (3) keeping the amount of product spoilage (outdating) at an acceptable level, and (4) maintaining quality by using the product while it is still fresh, and (5) keeping the cost of rotation low. Some of the above objectives are in conflict. Thus, certain redistribution policies may help attain one or more of these objectives to a greater extent. Redistribution involves the transfer of the product from outlets where demand is low to outlets where demand is high. A goal programming model for solving redistribution problems is presented. An example is provided and sensitivity analysis is performed in order to determine when redistribution is advantageous. Applicability of the model is discussed.

Who Gains from the Demographic Dividend? Forecasting Income by Age

Changes in the population age structure are known to influence the total income per person, but little is known about whether the changes are equally shared across the population or are concentrated on particular age groups and/or birth cohorts. The answer to this question has potentially important implications for income inequality, human capital investment, and fertility decision-making. We propose a new model of intergenerational transfers which distinguishes between the effects of changes in population structure and the effects of changes in family age structure. Using age-specific data from annual income and expenditure surveys of Taiwan between 1978 and 1998, we show that changes in age structure have had a very favorable effect on Taiwan's income growth. The gains are not equally shared by all age groups, however. Children and young adults have benefited the most, while the elderly have benefited the least. The population and family age structures have independent effects on per capita income; the effect of the population age structure is most important. Generational differences in per capita income are closely related to intergenerational differences in earnings, suggesting only a weak form of altruism. Finally, we predict that, on average, population aging will adversely influence the per capita income growth in Taiwan in the coming decades.

数量指标和质量指标理论与应用评析

在各类《统计学》教科书中,对数量指标和质量指标概念的解释不大一样,但基本的含义却是相同的.两者从概念上区别并不困难,也容易理解,但在对一些特殊问题的分析时,却不易把握,特别是在比较复杂的统计分析中,那就更不容易做出准确的判断了.怎样才能对数量指标和质量指标的应用做出科学的评价和分析.本文拟就这方面的问题做些初步探索.     

东亚汇率协调机制与中国的理性选择

1997年亚洲金融危机之后,汇率协调的重要性已在东亚各国政府及经济学界形成共识.对于如何建立东亚汇率协调机制,许多国家政府和经济学家都提出了解决方案,并进行了大量的实证研究.如东亚日元区方案、东亚美元本位方案、一篮子目标区爬升钉住方案、亚洲汇率机制方案以及编制亚洲货币单位方案等.但是,通过对比分析各种协调方案认为,目前在亚洲还不存在一种可行的稳定的汇率协调机制,因此,谋求人民币在亚洲地区作为关键货币的地位才是中国在东亚货币合作中的最大利益所在.

多元化战略、经济绩效与资本结构——关于上市公司股权融资偏好解释

我国上市公司存在十分强烈的股权融资偏好,学术界一般将其原因归结为股权融资成本偏低。笔者研究则表明,融资成本因素并不能全部解释上市公司股权融资偏好。本文从企业多元化经营战略角度来剖析股权融资偏好。研究发现:企业多元化程度越低负债率越低,企业经济绩效越好;企业有动力降低负债率,采用股权融资。研究还发现,企业多元化战略已经构成融资决策的有效约束,股权融资偏好是上市公司的理性选择。
