Capacity planning and resource allocation are crucial to the cost-effective delivery of health care services. In this paper, we present an analytic approach based on a modified version of the Holt-Winters multiplicative seasonality forecasting model to determine the frequency distribution associated with a hospital care unit's census. This paper is a follow-up to the census frequency distribution simulation model described in Lapierre et al. (Socio Econ. Plan. Sci. 33 (1999) 25). We demonstrate that our model can provide census frequency distributions equivalent to the simulation model of Lapierre et al. [1], but without the computational effort common to simulation models.  相似文献

由于各国经济发展水平、经济资源优势和经济国际化程度不同,各国都制定符合各自经济政策目标的国际投资税收政策,采取的税收优惠政策的侧重点也各不相同。跨国企业集团在制定投资战略时应注重分析各国引导投资的侧重点并充分加以利用,在投资战略选择中,必须慎重确定投资所在国的重点优惠项目或重点优惠地区,全面考虑投资国和投资所在国之间的国际税收协调性,正确认识资本投入量同税收负担与其他投资环境要素之间的关系。应以全球的观点进行国际化投资战略规划,以谋求集团整体税收负担的最小化和整体投资收益的最大化  相似文献

J. Kol 《De Economist》2004,152(2):273-296
Jan Tinbergen's scientific writings cover six main areas of research. His articles in De Economist represent these areas; in some cases the contributions to De Economist were of a pioneering nature (business cycles, economic models, economic integration); in others De Economist was the first or even single outlet for Tinbergen's work. This article provides an overview of these contributions. The wide scope of Tinbergen's areas of research goes together with a unity in approach, the characteristics of which are: policy relevance, quantification and measurement, balance in analysis and presentation, and learning from experience. Tinbergen's articles in De Economist bear witness to this approach which at the time also met with scepticism and resistance as this overview shows. According to Houthakker, Tinbergen's main contribution may be that, amidst the pleas of interest groups and the slogans of the laity, an attempt is made that the voice of the professional economic researcher be heard. Tinbergen's work still sets an agenda for both economic research and policy making.  相似文献

Abstract. Economists devote considerable energies towards refining their econometric techniques to overcome difficulties connected with conducting empirical research. Despite advances in technique. it is not clear whether further refinement in this direction is worthwhile for policy purposes. It may be that no further amount of statistical adjustment of inadequate data will increase understanding, and that better data is simply necessary to add to our knowledge. But rarely is sufficient credit paid to new forms of data. In short, econometric technique is emphasized to the neglect of data innovation, as if new data were merely lying about waiting for an ingenious suggestion for use. This paper surveys advances of the last twenty five years in estimating labour supply for policy purposes with a view towards appreciating the relative contribution of both improvements in econometric technique as well as developments of new data.
After briefly detailing the key parameters which economists have sought to estimate, we describe the early 'first generation' research (circa 1970), which is plagued by problems of unobservable variables, measurement errors, truncation and selectivity bias, and non linear budget constraints. 'Second generation' research constitute attempts to resolve one or more of these difficulties, and the respective contribution of econometric technique and new data is acknowledged and assessed, including the contribution of data generated by large scale social experiments in which participants are randomly assigned to different guaranteed income plans and their labour supply behaviour measured.  相似文献

During and after the Asian crisis, institutional investors and pension funds in Asian financial markets have been confronted with a number of difficulties effecting their performance and the way they carry out their role within the national pension system. We analyze these problems by comparing the actual investment policy of an institutional investor with an optimal investment strategy derived from the insights of modern portfolio theory. We also analyze whether the organizational set‐up of a pension fund allows it to adequately perform its role within the pension system. As an example, we examine the operations of the Thai Government Pension Fund (GPF). We find that allowing international investments and reducing restrictions on equity investments while lowering the implicit requirements for investments in government debt would allow the GPF to further diversify its investment risk and to increase its risk‐adjusted return. We also show that some changes in the governance structure of the GPF would lower the occurrence of conflicts of interest for the management and increase the efficiency of the GPF operations.  相似文献

Abstract. The use of CGE models has gained much popularity among policy analysts in LDCs and there is a fast growing body of literature on this area of economics. In this survey, the advantages of general equilibrium approach over partial equilibrium approach in analysing a wide range of policy issues are highlighted. The evolution of CGE modelling is discussed and more than 60 CGE applications related to different policy issues in LDCs are surveyed. This comprehensive survey shows that the CGE models have become quite popular analytical tools among policy analysts in LDCs over the last decade or so. The debate in the economic profession regarding the value and appropriateness of using CGE models for policy analysis is examined in the final section of this paper. Some of the criticisms levelled at CGE models are discussed and it is argued that despite this criticism such models are capable of providing insight into important policy problems.  相似文献

The phrase ‘demographic timebomb’ has taken on the aura of a shibbholeth and that everyone knows they ought to be fearful about. But is it really understood and what needs to be done? This article seeks to answer these questions and to shed some light on the employment strategies being developed by some British hospitality employers to counteract the demographic changes of the 1990s. As a result, some of the myth that the hospitality industry is lagging behind other industries can be dispelled but other findings support popular testimony that the industry faces special problems.  相似文献

在商品货币关系广泛存在的情况下,要想恰当有效地按比例分配社会劳动时间,既离不开市场的作用,也离不开计划的作用。这既为资本主义社会的实践所证明,也为社会主义社会的实践所证明。对这个问题进行深层次的分析,可以从生产关系与生产力、上层建筑与经济基础的关系上,从计划与市场的内在统一性上。从计划与市场两种手段的不同特点上找到理论根据。在市场经济条件下,并不排斥计划的作用,但计划工作必须进行改革使之与发展市场经济相适应。  相似文献
