银行效率DEA分析的可信度检验   总被引:1,自引:1,他引:1  
近年来涌现出大量基于DEA方法的银行效率这一热点问题的研究成果,但是由于DEA方法自身的局限性,诸如对效率值的估计偏低且离散程度较大,以及不能方便地检验结果的显著性等等问题,使其研究的结果受到影响;而Bootstrap技术是基于对经验数据及其相关估计的重复抽样来提高估计置信区间和临界值精度的统计技术,可有效地克服DEA方法结果可信度的这种内在依赖性。本文给出了基于Boot-strap技术的DEA方法来计量银行效率的手段,提高了效率分析结果的可信度,并对我国四大国有商业银行的效率进行了对比性实证分析。  相似文献

本文通过建立内生经济增长理论模型,利用我国1996~2009年30个省份的面板数据,建立空间面板数据模型考察银行业竞争结构对国际贸易影响的区域差异性。研究结果表明,在控制银行业竞争结构、外商直接投资水平等差异后,各省份国际贸易的增长符合条件β收敛假说,表明省际间银行业竞争结构差异是造成各省份对外贸易差异的原因,缩小省际间银行业结构差异,加快落后地区中小银行的发展,提升银行业的竞争力度有利于国际贸易差距的减小。本文为通过改善银行业的结构关系可以促进内陆开放经济高地建设提供了理论及实证依据。  相似文献

已有文献的比较分析表明,基于Panzar-Rosse模型对我国银行业市场竞争度的估计存在不一致,通过实证检验发现模型设定与变量度量的差异是引起结论不一致的主要原因。本文着重对模型的正确设定和变量的准确度量进行了讨论,并使用2003~2010年14家商业银行的数据进行验证。结果表明,该时期我国银行业处于垄断竞争状态,而2008年国际金融危机后市场竞争度明显下降,这一结果对于替代性变量度量的选取非常稳健。  相似文献

We study Internet-primary banks for differences in performance versus newly chartered traditional banks from 1996 through 2003. Internet-primary banks are larger, with lower net interest margins and loan losses, and higher wage and physical capital rates than newly chartered traditional banks. Univariate ROE is lower, but profit efficiency is significantly higher on average for Internet-primary banks compared to all newly chartered banks as well as those that survive through the sample period. In multivariate models, Internet-primary banks continue to have significantly higher average profit efficiency, and particularly so when of sufficient size.

本文讨论了存在成本差异的第三国市场模型的最佳贸易与产业政策选择问题,讨论了社会成本和私人成本、本国和外国成本差异情况下的Cournot竞争和Bertrand竞争的情况。本文发现,在Cournot竞争下,政府首先行动时,当政府基金影子价格低于4/3时,政府对出口进行补贴,并且本国越有成本优势,补贴越高,补贴的利润转移效应越大;当政府基金影子价格高于4/3时,政府对出口征收出口税,且本国越有成本优势,征税越多。在Bertrand竞争下,当政府先行动时,对出口征收出口税;当政府后行动时,对出口进行补贴。当本国企业具有劣势时,事后补贴是最佳政蓑。  相似文献

Tit for tat in small steps: the internationalization of Swedish banks   总被引:2,自引:0,他引:2  
Earlier studies of the internationalization of manufacturing firms have shown that they tend to start their foreign operations in countries that are culturally close to their own and then gradually move to more alien ground. If banks follow their customers abroad, we would expect their internationalization to assume a similar pattern. Their penetration of foreign markets could also be expected to be related to direct foreign investments and exports. An empirical test in the case of major Swedish banks did not support this hypothesis. Instead these banks tended to concentrate their internationalization efforts to important financial centres. Thus they have not only chosen to establish themselves in places where many international banks are already working, but they have also tended to follow each other in a pattern of tit for tat. The nature of this process supports the idea suggested in earlier studies that internationalization is generally a gradual process, starting with minor commitments which are developed over time.  相似文献

The recent financial crisis has focused the attention of scholars and policymakers on how to improve financial stability through better macro‐prudential regulation and supervision. In this paper, we compare the existing theoretical and empirical literature on contagion through the banking system. It is argued that the structure of the interbank market, the size of banks, the linkages among them, the level of correlation of their investments and the transparency of the regulator are key factors in determining the possibility of contagion. We discuss the different findings and present avenues for future research.  相似文献

We use a translog functional form to estimate a stochastic frontier function of cost and profit efficiency (PE) of Ghanaian banks under the Battese–Coelli time‐varying decaying inefficiency parameterization for (unbalanced) panel data. We regressed efficiency estimates on a distance variable controlling for bank size, total cost, and profits. We find that Ghanaian bank PE is worsening, whereas cost efficiency is improving for the period analyzed. Our results show that PE is not related to distance, size, or cost and profitability ratios. Distance is however positively and significantly related to cost efficiency. Cost efficiency is however not influenced by size or cost and profit ratios.

A dynamic theory of efficiency improving input reallocations is presented which relaxes the assumption that decision-making units have the ability to reorganize their activities instantaneously to achieve efficient input allocations. Explicit account is taken of the decision-making unit’s gradual transition to an efficient input allocation. A balanced panel data set covering 906 U.S. agricultural banks is constructed for the period 1996–2000 and we find that these banks are allocatively efficient but technically inefficient. The explicit solution for the optimal input use finds evidence of gradual transitions for two of the three inputs, with the labor input transition being the slowest. The efficiency improving path finds the firm transitions toward an efficient allocation by simultaneously improving on technical efficiency instantaneously and on allocative efficiency intertemporally, which suggests a non-linear path toward the most efficient allocation.  相似文献

随着信息技术的进步和互联网的普及,我国网上银行业务得以快速发展。在充分肯定网银业务优越性的同时,也应该看到,由于我国网银业务还处于发展阶段,运行中出现了诸多的问题,甚至损害了客户的利益,以致客户与银行之间出现了不少的纠纷,一定程度上影响到了社会公众的认可度,制约了网银业务的健康发展。该文主要是从研究和解决这些纠纷入手,提出要加强对网银业务各参与方的正确引导,进一步规范业务行为,改善网银业务发展环境,防范市场风险,化解各方矛盾纠纷,提高网银业务的整体应用水平。  相似文献

This paper applies a life-cycle model with individual income uncertainty in order to investigate the determinants of credit to households. We show that the household credit to GDP ratio depends on the lending-deposit interest rate spread, individual income uncertainty, and individual income persistence. We subsequently provide empirical evidence for the prediction of a theoretical model on the basis of data from OECD and EU countries.  相似文献

The Expert System that one of the authors had developed during his dissertation was tried on the data set of the M3 Competition. The expert system was originally designed to forecast monthly demand for industrial products in a distribution environment and was modified to run the data. The results of the application of the system were mixed as in some of the time series the results were statistically undistinguishable with the exception of the monthly series. In general, the intervention did not improve the accuracy and the effort required to do it was substantial.  相似文献

Many recent empirical studies show that both banking crises and financial development (FD) play an important role in understanding the dynamics of income inequality (IncI) over the last decades. However, so far no study has investigated the role of FD in the amplification of IncI following banking crises. This paper seeks to address this issue based on a sample of 69 banking crises in 54 countries over the 1977–2013 period. Our analysis suggests that FD is associated with a significant increase in IncI in the aftermath of banking crises. This result is robust to a broad range of alternative specifications and is unaffected by various potential sources of endogeneity. We also show that the relationship between FD and the redistributive consequences of banking crises is not subject to a threshold effect and is stronger for developing countries.  相似文献

契约储蓄机构包括养老基金和寿险公司。养老基金和寿险公司的特殊之处在于他们的债务期限为长期结构。这类储蓄机构的投资可以使金融市场上长期资金的供给增加,也由于其投资的长期性,使证券市场的效率、透明度和竞争程度整体上会得到提高,交易成本趋于下降。此外,使银行的行为更加理性化、长期化,从而使得金融市场上的资金需求方企业可以以更低的成本获得更多的长期资金,促进整个金融体系的健康稳定发展。  相似文献

中国分省区FDI的引进效率评价与解析   总被引:6,自引:0,他引:6  
本文用非参数DEA方法评价和分析了中国各省区1998~2000年和2001-2003年两个时期FDI的引进效率。研究发现,在1998-2000年优势充分发挥的省区是:福建、广东、广西和海南,优势发挥严重不足的地区是青海和新疆;在2001-2003年优势充分发挥的省区是:江苏、江西和海南,优势发挥严重不足的地区是宁夏和新疆。效率分解的结果使我们发现新疆效率低下的主要原因是规模效率低下,宁夏效率低下的主要原因是拥挤测度太低,而青海效率低下的原因则是来自规模效率和拥挤测度两方面。  相似文献
