中国银行业规模经济和范围经济研究

中国银行产业是中国经济发展的支柱,银行产业发展的态势影响中国经济的发展,在一定范围内,规模经济和范围经济有一定的联系,也有一定的制约,本论文从基本概念、二者之间的关系、银行业规模经济和范围经济研究的方法进行阐述。     

基于广义超越对数成本函数的商业银行范围经济实证研究

从业务收益变化的角度,通过构建商业银行广义超越对数成本函数的面板固定效应模型及范围经济的测度方程,对中国不同类型商业银行1997～2006年的范围经济进行实证和对比分析得出:从整体上看,中国商业银行呈现范围经济效应,但中国商业银行的范围经济还没有达到最佳的状态;范围经济与商业银行中间业务及投资业务的发展有关,股份制商业银行的范围经济优于国有商业银行.     

我国商业银行范围经济的实证研究——基于广义超越对数成本函数的分析

本文运用基于BOX—COX转换的广义超越对数成本函数,利用我国八家商业银行1996—2007年的面板数据,实证测算了它们的范围经济状况。研究结果表明：（1）国有商业银行的范围经济程度大于股份商业银行;（2）国有商业银行中,中国农业银行和中国银行的范围经济程度总体呈上升态势,而中国工商银行和中国建设银行的范围经济程度总体呈下降趋势;（3）股份制商业银行中,华夏银行和民生银行的范围不经济程度在逐步降低,而交通银行和中信银行的范围不经济程度变化不大。     

我国商业银行规模经济和范围经济的实证研究

本文利用广义超越对数成本函数,分组研究了我国14家商业银行2001—2010年的面板数据,结果表明:股份制商业银行的总体规模经济略好于国有控股商业银行,但在贷款特定产出规模经济方面要逊于国有控股商业银行;国有控股商业银行的范围经济要好于股份制商业银行,在特定产出范围经济方面,贷款与存款、投资与存款存在成本互补,贷款与投资存在较轻程度的范围不经济。     

中国商业银行的效率分析——基于广义超对数成本函数的范围经济检验

本文运用基于BOX-COX转换的广义超对数成本函数,从范围经济角度,对我国商业银行1995年到2005年的效率进行了经验分析.结果表明,我国的国有商业银行存在着范围不经济,而股份制商业银行存在着范围经济,这说明股份制商业银行的效率高于国有商业银行.因此,要提高我国商业银行的效率,必须大力发展股份制商业银行,允许商业银行适度混业经营.

中国农业保险公司的规模经济和范围经济研究

本文以描述分析中国农业保险公司的规模、业务结构和经营地域变动情况为基础,利用面板数据回归分析发现,中国农险公司存在虽减弱但仍明显的规模经济和范围经济。进一步检验发现,农险公司的规模对规模经济和范围经济的影响并不显著;农险业务比重对规模经济的影响负向显著,对范围经济的影响正向显著;跨地区经营程度对范围经济的影响负向显著。实证结果支持中国农险公司扩大规模,加强多元化经营尤其是发展非农险业务,扩展经营区域,以更好地加强或保持规模经济和范围经济收益,这同时需要相关政策的支持。     

基于TCF函数的中国城市商业银行规模经济探究

通过收集52家城商行年度报告数据,建立超越对数成本函数（TCF）,得出规模经济系数,进而判断我国城商行的规模经济效应。同时,建立规模因子与资产规模的散点图,得出城商行的规模经济变动趋势,并据此分别得出不同资产规模的城商行发展战略。     

基于规模经济的西方银行业并购理论与中国银行业的实证分析

银行并购的一个重要理论支持即是规模经济理论,本文利用DEA模型和Tobit模型来研究我国商业银行的规模经济,对我国商业银行2003-2005年间的规模经济及其影响因素进行了实证分析,最后对我国商业银行在并购中如何谋求规模经济提出一些建议。     

A Multi-Product Cost Study of the U.S. Life Insurance Industry

This paper reports estimates of overall and product specific economies of scale, as well as, economies of scope for the main outputs of the life insurance industry. In addition, the paper presents a number of structural tests of the production technology. The results indicate that the estimated cost function satisfies the regularity conditions, that the industry exhibits overall and product specific economies of scale, and that there are significant economies of scope between the main lines of business.     

Are European banks too big? Evidence on economies of scale

In light of the policy debate on too-big-to-fail we investigate evidence of economies of scale for 103 European listed banks over 2000–2011. Using the Stochastic Frontier Approach, the results show that economies of scale are widespread across different size classes of banks and are especially large for the biggest banks. At the country level, banks operating in the smallest financial systems and the countries most affected by the financial crises realize the lowest scale economies (including diseconomies) due to the reduction in production capacity. As for the determinants of scale economies, these mainly emanate from banks oriented toward investment banking, with higher liquidity, lower Tier 1 capital, those that contributed less to systemic risk during the crises, and those with too-big-to-fail status.     

Effect of fund size on the performance of Australian superannuation funds

This study examines the relationship between fund size and performance for two major superannuation industry sectors in Australia: retail and not‐for‐profit, using a unique but confidential database. Results suggest that members benefit from being invested in larger superannuation funds for three reasons: (i) larger not‐for‐profit funds provide diversification benefits of investing in more asset classes including unlisted property and private equity, (ii) larger funds in both sectors avoid the scale diseconomies in investment returns documented in studies of equity mutual funds and (iii) larger funds make substantial savings by spreading fixed operating costs (such as IT infrastructure) over a larger asset base.     

The joint determination of audit fees, non-audit fees, and abnormal accruals

Prior research has estimated piece-meal the determinants of audit fees, non-audit fees and abnormal accruals. Intuition, informal analysis, and a variety of theories suggest that audit fees, non-audit fees, and abnormal accruals are jointly determined. We address this endogeneity issue by modeling the confluence of audit fees, fees for non-audit services and abnormal accruals in a system of simultaneous equations. Our joint estimation provides a starting point to look simultaneously at several competing theories. Using audit and non-audit fee data from the UK for 1994–2000, we find evidence consistent with knowledge spillovers (or economies of scope) from auditing to non-audit services and from non-audit services to auditing. While knowledge spillovers from non-audit services to auditing have been found in prior research [e.g. see Simunic, 1984], the presence of knowledge spillovers from auditing to non-audit services is a new result. Contrary to recent results in Ferguson et al. (2000) and Frankel et al. (2002), we do not find support for the assertion that fees for non-audit services increase abnormal accruals. In fact, contrary to the results in Ashbaugh et al. (2003) and Chung and Kallapur (2003), we find that non-audit fees decrease abnormal accruals, which we attribute to the productive effects of non-audit services. We also find evidence that audit fees increase abnormal accruals, consistent with behavioral theories of unconscious influence or bias in the auditor-client relation. The findings are robust to tests with US data. JEL Classification C30 · M40 · M41 · M49
