Engle-Granger representation theory is used to estimate the secular and cyclical determinants of business output in Israel during 1960–1988. The specification of the secular production function is based on the technique of cointegration, while the cyclical, or short-term, production function is specified in terms of an error correction model. In the preferred model of the secular production function returns to scale are slightly increasing and the productivity of Palestinian workers is approximately 40 percent of Israeli workers. In the short-term production function total factor productivity is pro-cyclical. 相似文献

自主创新是当前商业界和学术界研究比较热的话题。政府相应地制定了一系列的政策和法规来鼓励企业进行自主创新。在这种背景下,我国的医药企业也积极响应国家的政策进行自主创新。然而,医药企业创新在实际操作中的行动方向差异很大。针对这种差异,笔者将医药企业创新划分成新功能创新和新设计创新两种,并且通过对一系列的数据和资料分析后,发现我国的医药企业的创新并非实质上的自主创新即新功能创新,而是新设计创新。文中对产生这种局面的演化机制进行了分析。 相似文献

Technology foresight as a policy intelligence tool can offer vital inputs for policy-making in various domains. The relationship between foresight and policy-making has been presented in the literature by the policy-related functions of foresight, but the literature reflects a theoretical gap with the systematic evaluation model for the impact of foresight on policy-making. This research seeks to bridge the existing gap and uses the mixed method for this purpose. The mixed method approach used in this paper is the sequential exploratory design. First, the conceptual model is developed in the qualitative part of this research by using meta-synthesis and constant comparative method (CCM) of analysis. Second, in the quantitative part, quantitative tests are used to evaluate the dimensions and components of the developed theoretical model. The data collection tool is a questionnaire. The results confirm the proposed dimensions of the evaluation model. 相似文献

The author discusses several issues that instructors of introductory macroeconomics courses should consider when introducing imports in the Keynesian expenditure model. The analysis suggests that the specification of the import function should partially, if not completely, be the result of a simple discussion about the spending and import behaviors of the household, firm, and government sectors. The analysis also indicates that instructors who use certain import functions that are in some introductory textbooks will inadvertently impose restrictions on the model and potentially confuse students. The author examines several implications of the specification proposed by Robert Cherry (2001) and shows how the restrictions imposed by Cherry's specification make it difficult for instructors to present certain types of economic events and policies. The import function discussed here avoids these restrictions and allows instructors to present more easily certain types of examples. 相似文献

Non-convex Technologies and Cost Functions: Definitions,Duality and Nonparametric Tests of Convexity 总被引:1,自引:0,他引:1
Walter?Briec Kristiaan?KerstensEmail author Philippe Venden?Eeckaut 《Journal of Economics》2004,81(2):155-192
This contribution is the first systematic attempt to develop a series of nonparametric, deterministic technologies and cost
functions without maintaining convexity. Specifically, we introduce returns to scale assumptions into an existing non-convex
technology and, dual to these technologies, define non-convex cost functions that are never lower than their convex counterparts.
Both non-convex technologies and cost functions (total, ray-average and marginal) are characterized by closed form expressions.
Furthermore, a local duality result is established between a local cost function and the input distance function. Finally,
nonparametric goodness-of-fit tests for convexity are developed as a first step towards making it a statistically testable
hypothesis.
