This study analyses the impact of OBS on banking productivity growth using a sample of 712 banks from 84 countries between 1999 and 2006. Our international setting allows us to analyse differences on the performance on banking institutions among various groups of countries with different economic and financial innovations development. We estimate cost and profit productivity growth using a parametric approach that decomposes the change in risk-adjusted cost and profit performance into two main components: changes in business conditions and changes in productivity. The latter one is decomposed further into the change in best practice and change in (in)efficiency. 相似文献

本文一方面结合我国金融市场化与开放进程的沿革路径,构建中国金融自由化指数;另一方面采用非参数的数据包络分析方法计算Malmquist指数,以此来衡量银行效率。在此基础上,我们对中国金融自由化进程与银行效率的内在关联展开计量分析。研究发现,伴随着中国金融市场化与开放政策的渐近推进和逐步深化,中国银行业的整体效率有了明显的改善。这其中受益良多的是股份制商业银行,而国有商业银行的效率虽有所改善,但成效并不明显。 相似文献

As banking consolidation proceeds and Europe moves toward a single market, cross-country differences in banking efficiency can affect the future competitive position of a country’s financial market, helping to determine which European money centers may expand or contract. Looking at large banks across 10 countries, we find they are roughly equally efficient after controlling for differences in business environment, banking costs, and bank productivity. As no country seems to have a strong efficiency advantage, it seems likely that state efforts to promote “national champions” through favorable mergers which expand scale and market share may determine the outcome. 相似文献

This paper presents a benchmarking analysis of the branches and regional banks of a large French banking group. The analysis focuses on operational performance. Starting from an ‘individual’ diagnosis at branch level, a ‘network’ diagnosis is developed at regional bank level. The aim of the paper is to develop (i) operational performance indicators from the inefficiency score and (ii) a benchmarking procedure adapted to the network structure of the banking group under study. The banking group comprises 1611 branches that form 16 regional groups. The branches operate in six different business environments. A method is therefore required (a) to aggregate the inefficiency scores of individual branches to evaluate the regional groups and (b) to integrate the differences in environment into the evaluation procedure. Inefficiency scores are calculated using the data envelopment analysis (DEA) approach. This is based on the principle of comparison; once identified, the best practices are used to construct the efficiency frontier. Each entity is then positioned relative to that frontier. The model proposed in this paper determines one efficiency frontier for each type of environment. The results reveal that 30% of branches are efficient. Special emphasis is placed on quantifying productivity gains at regional bank level and on practicing intra- and inter-regional bank benchmarking. 相似文献

Information management is a core process in banking that can resolve information asymmetries and thereby help to mitigate competitive pressure. We test if the use of information technology (IT) contributes to bank output, and how IT-augmented bank productivity relates to differences in market power. Detailed bank-level information on the use of IT reveals a substantial upward bias in bank productivity estimates when ignoring banks’ IT expenditures. IT-augmented bank productivity correlates positively with Lerner markups. A mere increase in IT expenditures, however, reduces markups. Results hold across a range of bank output definitions and productivity estimation methods. 相似文献

This paper develops a model of regulated Brownian motion with an endogenous profit term to analyze the role of regulatory credibility on the stability and productivity of the banking system. We show that when regulatory intervention is perfect and costless, the volatility of the system can be substantially reduced with no loss of productivity. In fact, perfect credibility can actually reduce the volatility of intrinsically risky banking systems below the volatility of intrinsically less risky systems as banks anticipate intervention and mitigate their investment behaviour accordingly. However, when the credibility of the regime is weakened because of increased uncertainty stemming from regulation, such as random costs or imperfect timing of regulatory intervention, both the stability and productivity of the financial system are impaired. Importantly, we find that in the presence of regulatory costs and imperfect credibility, there is no universal optimal intervention policy rule. The optimal regulatory system depends on the regulator’s level of absolute risk aversion. 相似文献

在深化银行业供给侧结构性改革背景下,如何科学评价银行业的结构性全要素生产率(TFP)增长具有重要意义。区别于早期针对个体样本的技术性TFP增长研究,本文通过构建并分解加总的Luenberger生产率指标对我国银行业以及不同类型银行的结构性TFP增长及来源进行有效评价。结果显示,研究期间,我国银行业的结构性TFP增长表现良好,其中,整体技术进步是主要驱动力;进一步分解发现,制度创新改善和加总的个体技术进步推动了银行业结构性TFP增长。在整体效率变化方面,加总的个体技术效率变化和结构效率变化都有待提高,其中,范围效率变化是抑制结构效率改善的主要因素。考虑不同类型银行,制度创新变化对所有类型银行的结构性TFP增长都影响显著,加总的个体技术变化对股份制和地区性银行的结构性TFP增长贡献更突出;加总的个体技术效率变化、结构效率变化、范围效率变化和规模效率变化对不同类型银行的结构性TFP增长作用有限。 相似文献

This study examines the impact of deregulation and technological change on the productivity of Malaysian banks over the period 1989–1998. Malmquist indices constructed with nonparametric DEA techniques are decomposed into their pure efficiency, scale efficiency, and technological change components. Our findings indicate an erosion of banking productivity that masks divergent tendencies among its component elements. These are dominated by adverse effects of technological change, which are associated with a reduction in the labor intensity of banking activity. Consistent with the mixed findings reported in the literature, the present investigation suggests that regulatory reform and liberalization are not sufficient conditions for productivity improvement.

This paper develops a Luenberger productivity index that is applied to a technology where desirable and undesirable outputs are jointly produced and are possibly negative. The components of this Luenberger productivity index - the efficiency change and the components of the technological shift - are then decomposed into factors determined by the technology, adjusted and then for ‘risk and environment’, ‘risk management’ and ‘environmental effects’. The method is applied to Central and Eastern European banks operating during 1998-2003 utilising three alternative input/output methodologies (intermediation, production and profit/revenue). Additionally, the comparative analysis of the sensitivity of the productivity indices in the choice of the methodologies is undertaken using statistical and kernel density tests. It is found that the main driver of productivity change in Central and Eastern European banks is technological improvement. That is, in the beginning of the analysed period, the results hinged on the banks ability to capitalise on advanced technology and successfully take into account ‘risk and environmental’ factors. Whereas, in later periods, one of the most important factors of technological improvement/decline was ‘risk management’. Finally, the tests employed confirm previous findings, such as Pasiouras (2008) in this journal, that different input/output methodologies produce statistically different productivity results. Finally, we find that external factors, such as ‘risk in the economy’ and banking production, and a ‘corruption perception’ affect the productivity of banks. 相似文献

This paper aimed to identify the antecedents and corollary of customer readiness for co-production in customer-only co-production services using mobile banking services as a context. Using a structured questionnaire, data were gathered from a sample of mobile banking customers in Ghana and the UK and the data analysis was facilitated by structural equation modelling. From the findings, the antecedents were customer socialisation, customer self-efficacy and customer motivation and the corollary was service productivity. The findings provide managers of customer-only co-production or technology-based services particularly mobile banking services with the specific factors that can be managed strategically and tactically to enhance customer readiness for co-production and service productivity. This study is one of a kind to conceptualise and empirically identify the antecedents and corollary of customer readiness for co-production within the customer-only co-production context. However, as the study was limited to mobile banking services, future studies might test the research model in other customer-only technology-based services. 相似文献

This paper analyzes the relationship between banks’ divergent strategies toward specialization and diversification of financial activities and their ability to withstand a banking sector crash. We first generate market-based measures of banks’ systemic risk exposures using extreme value analysis. Systemic banking risk is measured as the tail beta, which equals the probability of a sharp decline in a bank’s stock price conditional on a crash in a banking index. Subsequently, the impact of (the correlation between) interest income and the components of non-interest income on this risk measure is assessed. The heterogeneity in extreme bank risk is attributed to differences in the scope of non-traditional banking activities: non-interest generating activities increase banks’ tail beta. In addition, smaller banks and better-capitalized banks are better able to withstand extremely adverse conditions. These relationships are stronger during turbulent times compared to normal economic conditions. Overall, diversifying financial activities under one umbrella institution does not improve banking system stability, which may explain why financial conglomerates trade at a discount. 相似文献

Given that technological innovations in the banking sector in industrialised countries have been shown to increase productivity of this industry around the world, then why did India shy away from adopting this technology until the 1990s? Why has India been a late adopter of technology in the banking industry when it could have reaped the benefits from the existing R&D expertise developed by innovators and early adopters? This article charts out the path of technological innovation in the Indian banking industry post-economic liberalisation (1991-2) and identifies initial conditions in terms of competitive environment and regulatory pressures that have contributed to the diffusion of these innovations. The article highlights the role of labour unions in public sector banks and their initial opposition to technological adoption. The empirical analysis demonstrates the superior performance of the early adopters of technology (private sector and foreign banks) as measured by productivity, returns on equity, and market share, as compared to the late or passive adopters (public sector banks). 相似文献

This article develops an index of money market pressure to identify banking crises. We define banking crises as periods in which there is excessive demand for liquidity in the money market. We begin with the theoretical foundation of this new method. With the newly defined crisis episodes, we examine the determinants of banking crises using data complied from 47 countries. We find that slowdown of real GDP, lower real interest rates, extremely high inflation, large fiscal deficits, and over-valued exchange rates tend to precede banking crises. The effects of monetary base growth on the probability of banking crises are negligible. 相似文献

Cross-country comparisons of traditional measures of concentration, such as the Herfindahl index, are of limited use for answering normative questions such as: ‘Is the banking system too concentrated in our country?’ This paper develops a measure of concentration, essentially by normalising the Herfindahl index by a minimum feasible value for that index based on market size for each country. A formal derivation is given, and the measure is related to the mark-up of price over marginal cost for banking services. The empirical implications of the new measure are illustrated by reference to some recent studies. 相似文献

Are the less productive banks catching up to the more productive ones and, if so, how quickly and by what means? The objective of this study is to answer these questions by looking for convergence in productivity among bank holding companies (BHCs) in the US Past research has identified two major factors governing productivity in the banking sector – scale economies and X-efficiency. If the gains from scale economies decline with firm size and if the only difference between BHCs lies in their initial size, then the initially smaller BHCs should eventually catch up to the initially larger ones because the former tend to grow more quickly. However, the findings from this study do not support this hypothesis of “absolute convergence”. Indeed, the findings show strong evidence for “conditional convergence”, which means that the steady-state productivity to which a BHC is converging is conditional on the BHCs own level of X-efficiency. Conditional convergence implies that initial differences in X-efficiency among BHCs can, between them, create permanent differences in steady-state productivity. 相似文献

The impact of foreign banks’ entry on the conventional banking sector has been well documented in the literature. However, empirical evidence on the impact of foreign banks’ entry on the Malaysian Islamic banking sector is completely missing from the literature. By employing the Malmquist Productivity Index method, the article provides, for the first time, empirical evidence on the impact of foreign banks’ entry on the efficiency and productivity of the Islamic banking sector. The empirical findings indicate that the De Novo foreign Islamic banks have been relatively more efficient and productive compared to their domestic and foreign Islamic bank counterparts. The results also suggest that the Malaysian Islamic banking sector has exhibited a higher level of total factor productivity during the post De Novo foreign Islamic banks’ entry period. 相似文献
