垄断与产权:我国利率市场化的制度性障碍 总被引:12,自引:0,他引:12
在缺乏竞争的金融体系下,借贷价格偏离均衡价格,消费剩余减少,资源配置扭曲,金融运行效率降低。在我国,资金供应依然主要由居于垄断地位的国有商业银行及其变种组成和资金需求依然主要由国有企业及其变种组成的情况下,利率市场化会使得资金价格扭曲和变形,理论上推演的利率市场化预期效果在很大程度上无法实现。我国利率市场化的时间表只能视微观经济主体市场化的进程而定。 相似文献

新古典生产函数的质疑与货币量值的生产函数 总被引:1,自引:0,他引:1
新古典理论以生产函数和效用函数为基础,建立了技术关系的稀缺资源有效配置理论,其核心是表明商品和要素稀缺性的相对价格.生产函数在微观尚可应用,但并不能用于解释总量经济和经济增长与波动问题.尤其是总供给完全取决于实物生产函数的投入产出关系,这与总需求分析所采用的货币支出是不协调的.货币量值的生产函数的推导表明,总供给只是企业的货币成本函数而不联系到技术上的投入产出关系,而所有的国民收入核算中的货币量值都只是表明人们经济关系的名义变量而与实物的技术关系或生产函数是完全无关的. 相似文献

指出了常用的主业鲜明率在实际使用中遇到的问题,主要问题是计算值会出现无意义的结果,并且对真实主营业务比率的反映会有不真实的情况,提出了修正的方法,即通过修正企业经营总体规模的方法进行修正,最后通过实际计算证明修正结果消除了无意义的结果,也更加真实地反映了主营业务的比率. 相似文献

Sequential estimation problems for the mean parameter of an exponential distribution has received much attention over the
years. Purely sequential and accelerated sequential estimators and their asymptotic second-order characteristics have been
laid out in the existing literature, both for minimum risk point as well as bounded length confidence interval estimation
of the mean parameter. Having obtained a data set from such sequentially designed experiments, the paper investigates estimation
problems for the associatedreliability function. Second-order approximations are provided for the bias and mean squared error of the proposed estimator of the reliability
function, first under a general setup. An ad hoc bias-corrected version is also introduced. Then, the proposed estimator is
investigated further under some specific sequential sampling strategies, already available in the literature. In the end,
simulation results are presented for comparing the proposed estimators of the reliability function for moderate sample sizes
and various sequential sampling strategies. 相似文献

For a balanced two-way mixed model, the maximum likelihood (ML) and restricted ML (REML) estimators of the variance components were obtained and compared under the non-negativity requirements of the variance components by L ee and K apadia (1984). In this note, for a mixed (random blocks) incomplete block model, explicit forms for the REML estimators of variance components are obtained. They are always non-negative and have smaller mean squared error (MSE) than the analysis of variance (AOV) estimators. The asymptotic sampling variances of the maximum likelihood (ML) estimators and the REML estimators are compared and the balanced incomplete block design (BIBD) is considered as a special case. The ML estimators are shown to have smaller asymptotic variances than the REML estimators, but a numerical result in the randomized complete block design (RCBD) demonstrated that the performances of the REML and ML estimators are not much different in the MSE sense. 相似文献

由于经济转型独特的初始条件,利率市场化不单单表现为放松利率管制,期间还交叉了一个利率定价传导机制重构的过程。利率定价传导机制取决于一国的金融制度与结构,尤其与货币市场的发育密切相关。目前,由于利率定价传导机制尚未完全成型,相应的利率市场化进程应以完善利率定价传导机制为重点,并最终完成以放松利率管制为主要特征的利率市场化改革。 相似文献

外生冲击与房地产真实价格波动--对1998~2003年中国31省(市、区)的实证研究 总被引:1,自引:0,他引:1
文章首先根据经济学模型界定了两个重要指标:自相关系数与收敛系数.认为不同的外生冲击对这两个系数有不同的影响,而它们决定了房地产真实价格波动形态的差异.在此基础上,文章利用1998~2003年中国31个省(市、区)的面板数据对中国房地产市场进行了实证研究,其结论是,在真实人均可支配收入和真实建筑成本较高、真实税后住宅抵押贷款利率较低的地区有较大的自相关系数和较小的收敛系数,从而房地产真实价格具有更大的波动性.为使房地产真实价格在均衡价格附近平稳运行,降低开发成本和提高消费者购买成本能收到较好的效果. 相似文献

The last few years have witnessed important advances in our understanding of time preference and social discounting. In particular, several rationales for the use of time-varying social discount rates have emerged. These rationales range from the ad hoc to the formal, with some founded solely in economic theory while others reflect principles of intergenerational equity. While these advances are to be applauded, the practitioner is left with a confusing array of rationales and the sense that almost any discount rate can be justified. This paper draws together these different strands and provides a critical review of past and present contributions to this literature. In addition to this we highlight some of the problems with employing DDRs in the decision-making process, the most pressing of which may be time inconsistency. We clarify their practical implications, and potential pitfalls, of the more credible rationales and argue that some approaches popular in environmental economics literature are ill-conceived. Finally, we illustrate the impact of different approaches by examining global warming and nuclear power investment. This includes an application and extension of Newell and Pizer [‘Discounting the benefits of climate change mitigation : how much do uncertain rates increase valuations?’ Journal of Environmental Economics and Management 46 (2003) 52] to UK interest rate data. 相似文献

We compare a number of models of post War US output growth in terms of the degree and pattern of non-linearity they impart
to the conditional mean, where we condition on either the previous period's growth rate, or the previous two periods' growth
rates. The conditional means are estimated non-parametrically using a nearest-neighbour technique on data simulated from the
models. In this way, we condense the complex, dynamic, responses that may be present in to graphical displays of the implied
conditional mean.
