摘要： 在有消费的经济系统中,在结构方阵 A 非负不可约但不要求非奇异的条件下证明了:若不按华罗庚教授提出的正特征向量法安排初始投入,则系统一定会失去平衡。所获得的几个定理推广了华罗庚教授生前给出的有关结果,并且与实际的经济系统更加接近。

摘要： 经济效益综合评价是产业结构和产业政策研究的重要内容。从系统工程观点来看,经济效益综合评价本质上是一个有限方案多目标决策问题。因此,本文拟从多目标决策角度提出一种新的用于工业经济效益综合评价的模型与方法。该模型与方法以多目标决策中的加权法为基础,运用客观赋权方法确定各经济效益评价指标间的加权系数,评价结果准确、可靠,不具有主观随意性。

摘要： This paper compares theories of well-being/welfare in economics and psychology. It suggests that economists have an appropriate conceptual framework but the wrong variables for explaining well-being, whereas psychologists have a confusing framework but appropriate variables. A framework derived from ''the new home economics'' (Becker, 1965, 1973, 1977;Lancaster, 1966;Juster et al., 1985;Pollak and Wachter, 1975), and especially from the work of F. Thomas Juster and his colleagues, is proposed for the purpose of integrating economic and psychological variables into an account of human well-being. Essentially the framework calls for investigation of the impact of a household's economic and psychological stocks (capital account) on the psychic income flows (current account) and overall well-being of its members. It is suggested that this framework is valuable for clarifying individual and household decisions as well as for explaining variance in well-being. Empirical assessment of existing frameworks and an illustration of how the proposed framework could be implemented are made with data drawn from a 5-wave Australian Quality of Life Panel Survey.

摘要： The design of a manufacturing strategy incorporates the decision of whether to focus or vertically integrate, or adopt a policy somewhere between the two extremes. Unfortunately, the literature contains few models that aid a manager in this decision process. In this paper we design a model to evaluate and compare various strategic alternatives along the focused factory-vertical integration continuum. By defining a point along this continuum as the percent of components manufactured internally that are needed to make one finished item (where 0 indicates complete focus and one manufacturing step, and 1 indicates full integration and 100 percent internal manufacturing) we are able to delineate the effects of the alternative decision strategies on flexibility and the firm's cash flow. The capital asset pricing model is invoked to assess the impact on the firm's risk and value.

摘要： This paper presents a simple equilibrium model of the cocaine industry in Peru, Bolivia, and Colombia (PBC). The purpose of the model is to represent the fundamental economic relations that determine the size of cocaine output, and to simulate the effects on the production sector of policy initiatives or other changes in the surrounding environment. Model results include: ''Crop substitution'' programs will have a neglible impact on the world cocaine market. Cocaine supply control strategies that seize and destroy 70% or less of production, without limiting the total level of production, will have little impact on the market. Changes in the size. of the world cocaine market have a relatively modest long-run impact on the standard of living of average workers in Peru, Bolivia, and Colombia. The results of this study are insensitive to the data uncertainties concerning the cocaine market.
