中国经济增长的长期机制问题一直以来都是理论界研究的热点问题。文章通过对1953—2004年与经济增长相关因素的统计数据的回归分析,并结合其他学者的研究成果,认为支撑我国经济增长的长期动力主要来自于要素投入,而要素投入的效果却与经济发展战略制定的一些非经济因素有关。 相似文献

Multinational companies face increasing risks arising from external risk factors, e.g. exchange rates, interest rates and commodity prices, which they have learned to hedge using derivatives. However, despite increasing disclosure requirements, a firm's net risk profile may not be transparent to shareholders. We develop the ‘Component Value‐at‐Risk (VaR)’ framework for companies to identify the multi‐dimensional downside risk profile as perceived by shareholders. This framework allows for decomposing downside risk into components that are attributable to each of the underlying risk factors. The firm can compare this perceived VaR, including its composition and dynamics, to an internal VaR based on net exposures as it is known to the company. Any differences may lead to surprises at times of earnings announcements and thus constitute a litigation threat to the firm. It may reduce this information asymmetry through targeted communication efforts. 相似文献

青年农民工市民化,是指他们在身份上获得城市居民相同的合法身份和社会权利的过程,最明显的标志是获得所在地的城市户口及相应的社会权利。但是在推进青年农民工市民化过程中,仍然存在着思想障碍、制度障碍、政策障碍、组织障碍、青年农民工自身素质障碍等方面的限制,制约了青年农民工市民化的顺利推进。 相似文献

This paper presents a multilateral comparison of relative levels and structures of costs of production in Japan, the US and West Germany. The analysis is carried out by using harmonized input–output tables, which are converted at US prices by using adjusted sectoral purchasing power parities. A new accounting methodology is derived from recent developments of index number theory, whereas the chosen multilateral comparison procedure gives results that are invariant with respect to the order of the pairs of countries examined. 相似文献

How Fast Do Banks Adjust? A Dynamic Model of Labor-Use with an Application to Swedish Banks 总被引:1,自引:0,他引:1

This paper deals with a dynamic adjustment process in which adjustment of a key variable input (labor) towards its desired level is modeled in a panel data context. The partial adjustment type model is extended to make the adjustment parameter both firm- and time-specific by specifying it as a function of firm- and time-specific variables. Desired level of labor use is represented by a labor requirement function, which is a function of outputs and other firm-specific variables. The catch-up factor is defined as the ratio of actual to desired level of employment. Productivity growth is then defined in terms of a shift in the desired level of labor use and the change in the catch-up factor. Swedish banking data is used as an application of the above model. 相似文献

We propose a new bivariate distribution following a GLM form i.e., natural exponential family given the constantly correlated covariance matrix. The proposed distribution can represent an independent bivariate gamma distribution as a special case. In order to derive the distribution we utilize an integrating factor method to satisfy the integrability condition of the quasi-score function. The derived distribution becomes a mixture of discrete and absolute continuous distributions. The proposal of our new bivariate distribution will make it possible to develop some bivariate generalized linear models. Further the discrete correlated bivariate distribution will also arise from an independent bivariate Poisson mass function by compounding our proposed distribution (Iwasaki and Tsubaki, 2002).Received March 2003 相似文献

基于多元统计分析的封闭式基金业绩评价 总被引:2,自引:0,他引:2
本文引入在险价值(VaR)和基金折价率指标,利用因子分析和聚类分析方法对基金业绩进行综合评价。实证分析发现我国封闭式基金收益率优于市场收益率,少数几只基金业绩相对突出,实现低风险高收益的目标。但封闭式基金折价幅度较大,基金内部收益水平与外部评价状况背离,反映了市场投资者的投资非理性现象。 相似文献

Charles Blackorby Daniel Primont R. Robert Russell 《Journal of Productivity Analysis》2007,28(3):203-208
We show that the Hotelling–Lau elasticity of substitution, an extension of the Allen–Uzawa elasticity to allow for optimal
output-quantity (or utility) responses to changes in factor prices, inherits all of the failings of the Allen–Uzawa elasticity
identified by Blackorby and Russell [(1989) Am Econ Rev 79: 882–888]. An analogous extension of the Morishima elasticity of
substitution to allow for output quantity changes preserves the salient properties of the original Hicksian notion of elasticity
of substitution.
We thank Paolo Bertoletti for drawing our attention to the issue addressed in this paper and for his comments on an earlier
draft. 相似文献
