On the concept of optimum population 总被引:4,自引:0,他引:4
Dasgupta PS 《The Review of economic studies》1969,36(3):295-318
The economic welfare of a community is affected by policies that determine both the rate of capital accumulation and the rate of growth of population. The optimum size of population at any point is time will depend on the size of the existing capital stock and the optimum rate of savings will depend on the existing number of people. Consequently, in this sense, a population policy cannot be developed without a concurrent savings policy. The criterion of optimality that will be used is the ma ximization of the total discounted welfare of all generations from now to infinity. The problem will be to select that rate of savings and that size of population at every moment which will achieve this maximum welfare if, in fact, a maximum exists. An inquiry is made into the existence of an optimum policy under various circumstances. An attempt is made to evaluate the consequences of various ethical beliefs. 相似文献

An application of the extended cross impact method to generating scenarios of social change in Japan
Scenarios of Japanese society in 2000 are obtained by applying an extended correlational cross impact analysis. Since the scope of the scenarios is extensive, a procedure is developed to generate the scenarios that consists of a preprocessing of the events of interest and a step-by-step application of a cross impact method. Three scenarios are described, based on a workshop where the procedure was applied. 相似文献

Historically, major consideration given to product management has focused on research and development or the introductory
stage of the product life cycle. The authors present an empirical study delineating the variables to be considered in the
product elimination process. More specifically, the elimination process is evaluated under a situation of poor product performance
despite a generally viable market. The basic objectives of the study were: to determine the significant variables in the product
elimination process of the Small Appliance Industry; to determine the relative importance of the variables; to examine the
interaction among variables. The data obtained through personal structured questionnaire interviews were analyzed and provided
a ranking of twenty-six variables relevant to the elimination process. Moreover, the Johnson's Hierarchical Clustering Schemes
was applied to determine the interaction among variables. The results indicate that profitability and financial variables
are most significant in the elimination decision-process. Second, the primary clusters of importance are concerned with market
share, market growth rate, consumer awareness, and competitive action. 相似文献

We search forstrategy-proof solutions in the context of (many-to-one) matching problems (Gale and Shapley, 1962). In this model, whenever the firms can
hire as many workers as they want (the capacities are unlimited) the stable set is a singleton. There exists aPareto efficient, individually rational, andstrategy-proof matching rule if and only if the capacities are unlimited. Furthermore, whenever the capacities unlimited, the matching rule
which selects the unique stable matching is the only matching rule that isPareto efficient, individually rational, andstrategy-proof. 相似文献

There is growing evidence of a litigation mentality rampant in organizations, which has created a legalistic mindset in many managers. Increasingly, managerial decisions are becoming dominated by a concern for what is legally defensible at the expense of broader social considerations such as justice and fairness. The papers in this special issue explore how this legalistic mindset has created new organizational and social dilemmas, and situations of law whithout justice. 相似文献

Summary In the study of information theoretic measures, additivity has been the basic requirement. However it is quite interesting to investigate the sub-additive measures. Starting from subadditivity for measures associated with a pair of distributions of a discrete random variable, it has been changed into an equality relation using another function of a pair of distributions., Under the sum property of the function and the measures, the relation is expressed in terms of a functional equation of which the most general complex solutions have been obtained. In terms of the real continuous solutions of the functional equation, the sub-additive measures of Relative information and Inaccuracy have been defined and characterized. Particular cases and simple properties particularly the convexities of some of these new measures have also been studied. 相似文献

Much research on internal labor markets has been hampered by the failure to differentiate the wide variety of ILMs, by accounts of their determinants that too heavily emphasize isolated causal factors, by the lack of detailed material describing the economic and organizational dimensions of their design and implementation, and by the neglect of managerial perceptions of and motivations for constructing ILMs. This paper presents detailed case studies of three organizations that have constructed very different ILMs. Based on this material, a model of the determinants of ILMs is developed that centers around the concepts of costs, commitment, and rewards and that attempts to assess the interactions of effects of markets and hierarchies on ILMs. The model is built on the premise that the underlying imperatives typically held to affect ILMs are inevitably filtered through managerial beliefs and the constraints on managerial decision making. The implications of these findings for theory and research on ILMs are discussed. 相似文献

The paper presents an empirical model of wage determination in the public sector that leads to the specification of a system of interrelated wage equations for municipal employees, which allows for occupational and geographic interdependence of wages. The model also considers the influence of public employee unions, municipal government form, and monopsony power of local governments on the wages of municipal employees. Several variants of the derived system of equations are estimated based upon 1967 cross-section data for 478 cities, and the policy implications of the results are discussed. 相似文献
