金融一体化是欧洲一体化建设的重要内容,是当代欧洲金融业发展中的一个突出特征。本文考察欧洲金融业一体化的状态与效应,以及伴随着一体化进程逐步形成的金融稳定性框架。本文的分析显示,实行单一货币制以来,欧洲金融一体化不断深入,推动金融业市场的集中度与竞争性和效率提高,但是在当前金融危机的冲击下,缺乏联合统一行动机制的欧洲金融稳定性安排暴露出了明显的内在缺陷,需要有深度的改革。 相似文献

This paper shows that the divine‐coincidence does not hold in a sticky price model with external habit if a time‐varying tax rate on labor income is not implemented to fully eliminate the time‐varying distortions associated with external habit and monopoly power in goods market. The required labor income tax rate is inversely related to the risk‐free real interest rate and the markup in the goods market, but it is proportional to the degree of external habit. Under this circumstance, the optimal monetary policy commands a countercyclical interest rate, having a perfect negative correlation with tax rate in the sticky price model with external habit. If a time‐invariant tax is the only fiscal instrument, then the degree of external habit entails a gap between the private marginal rate of substitution between consumption and labor and the social marginal rate of substitution, generating an endogenous trade‐off between the stabilization of welfare‐relevant output gap and inflation. Under this circumstance, price stability is not the optimal policy. The monetary policy authority should optimally try to undo the time‐varying distortions associated with external habit and monopoly power in goods market by deviating from price stability. 相似文献

金融机构的资金来源方式、资金运用方式会影响金融机构本身和金融体系的杠杆率与稳定性。若金融机构或金融体系主要通过金融市场融资,资金运用主要集中于金融资产,并且通过金融资产进行再融资的规模不受限制,那么面对宏观经济或金融市场的冲击,这种类型的金融机构或金融体系的杠杆率会快速下降,在其资产和负债的期限错配较严重时,资金链条就会断裂,引发系统性金融风险。通过分析不同的资金来源和运用方式对金融机构杠杆率产生的影响,并结合历史上数次金融危机的教训,针对杠杆率快速下降时如何维护金融稳定提出了政策建议。 相似文献

The temporal nature of growth determinants in new bank foundings: implications for new venture research design 总被引:1,自引:0,他引:1
Several authors have suggested the founding period as a critical time in the development of a firm, arguing that the resource and decision choices made at this point have a substantive impact on the firm's future. Yet, historically, most studies have measured new venture choices considerably after the founding period. We suggest that the uniqueness of the founding event is important and test its validity through the examination of two implicit assertions. These implicit assertions are those of temporal stability and temporal locus of growth determinants. 相似文献

EXISTENCE OF A NONNEGATIVE EQUILIBRIUM PRICE VECTOR IN THE MEAN-VARIANCE CAPITAL MARKET 总被引:5,自引:0,他引:5
We derive a necessary and sufficient condition for the existence of a nonnegative equilibrium price vector under which the total demand and supply of each asset balances in the standard mean-variance capital market. Also, we give an explicit formula for such a price vector. This formula shows that the price of assets is an increasing function of , the weighted average of the requested rate of return of individual investors, which tends to infinity as approaches the expected rate of return on the market portfolio. Further, we construct a macroeconomic index which gives information about the soundness of the capital market. 相似文献

近年来,人民币汇率问题一直是各方面争论的焦点。现在,人民币汇率升值2%,并且不再盯住单一美元,而是参考“一篮子货币”定值。由于人民币汇率调整幅度比较小,所以,短期内会对我国经济产生一定的影响,从长期来看,影响比较小。人民币汇率水平,短期内是会保持比较稳定,但长期来看又存在着值得注意的问题。 相似文献

In this paper, we examine the over-time behavior of brand loyalty for a large set of brands drawn from 21 consumer packaged goods categories. Using the brand-loyalty operationalization of Colombo and Morrison (1989), the following conclusions are obtained. First, little support is found for the often-heard contention that brand loyalty is gradually declining over time. Second, while the short-run variability around a brand's mean loyalty level is not negligible, no evidence is found that this variability has systematically increased over time, and it can be reduced considerably through a simple smoothing procedure. Finally, the brand-loyalty pattern for market-share leaders is found to be more stable than for other brands. The study findings were robust to variation in the time interval used to construct the switching matrices, and to different treatments of multiple purchases. 相似文献
