How efficient is the banking system of Asia’s next economic dragon? Evidence from rolling DEA windows

Vietnam is now widely regarded as a rising economic star and the next economic dragon of Asia. Its banking system has played a key role in this stellar economic performance. Since 1990, Vietnam’s banking system has undergone significant changes which saw its composition transformed from being state banks only to now being both state as well as private banks, and has performed generally well in terms of growth, profitability and stability. But is it efficient? We conduct a dynamic analysis of the level and trend of the cost and profit efficiency of the Vietnamese banking sector over the period 1995 to 2011 taking into account the Asian and Global Financial crises. We use the Data Envelopment Analysis (DEA) Windows Analysis approach and adjust for bank size in calculating the average efficiency score of the banking system. Our empirical findings show that the cost and profit efficiency of the Vietnamese banking system averaged around 0.90 and 0.75, respectively, with the state banks being more efficient than the private banks and with efficiency experiencing an upward trend over the analysis period. Moreover, we find that the Global Financial Crisis (GFC) and Asian Financial Crisis (AFC) did not significantly affect the efficiency of the whole Vietnamese banking system.     

外资银行进入对发展中国家银行信贷可得性的影响研究

如何引导外资银行增加东道国的信贷可得性,尤其是中小企业的信贷可得性,是目前理论和政策界争论的焦点问题之一。本文通过构建一个理论模型,分析了外资银行进入和国内信贷供给的关系,从市场均衡结果、社会福利、成本效率等几个角度对外资银行进入发展中的东道国的影响进行综合分析。模型结果表明,外资银行的进入并不必然增加一国的总体信贷水平、也并不必然提高东道国银行业的成本效率和整体社会福利,甚至在某些特定条件下,结果可能适得其反。     

Foreign bank entry,bank efficiency and market power in Central and Eastern European Countries1

This article analyses the implications of the recently observed sharp expansion of foreign banks in the Central and Eastern European Countries (CEECs) as measured by equity ownership. We show that the mode of foreign entry has a pivotal impact on the post‐entry performance of banks in CEECs. Foreign greenfield banks are characterized by superior cost efficiency, compared with domestic and foreign‐acquired banks. The efficiency of foreign‐acquired banks deteriorates in the initial year of acquisition, but improves thereafter. Banks acquired by foreigners have less market power relative to domestic and foreign greenfield banks. Overall, the CEEC banking sectors have benefited from the increased foreign bank participation, both in terms of higher efficiency and more competition.     

Management Behaviour in Vietnamese Commercial Banks

This study identifies managerial behaviour in Vietnamese banks between the years 2000 and 2014, based on the managerial framework of banks, as identified by Rossi et al. ( 2009 ). This framework is built on the interrelationships between efficiency, risk, capital and diversification. This study uses the Z‐score to measure insolvency risk, the SFA to estimate cost efficiency, the ratio of total equity to total assets to capture bank capital and the HHI index to measure the diversification of revenue and earning assets. The results from the 3SLS estimator indicate that revenue diversification has an insignificant impact on insolvency risk, capital ratio and cost efficiency, but earning assets diversification has a negative effect on these three variables, supporting ‘classical diversification’, ‘economic capital’ and ‘monitoring’ behaviours. Moreover, a decline in cost efficiency leads to a rise in insolvency risk, implying ‘bad management’ behaviour; an increase in risk results in a reduction in cost efficiency, indicating ‘bad luck’ behaviour; and a reduction in capital ratio in the poorly capitalised banks leads to a growth in risk, suggesting ‘moral hazard’ behaviour. The results remain strongly robust when using an alternative risk measurement (the loan loss provision ratio) and an alternative SFA model.     

WHAT CAUSES THE EFFICIENCY AND THE TECHNOLOGY GAP UNDER DIFFERENT OWNERSHIP STRUCTURES IN THE CHINESE BANKING INDUSTRY?

This paper estimates and compares the cost efficiency of the Chinese banking industry among different ownership types for the period 2003–2014, using the stochastic metafrontier model. We find that foreign banks have the lowest cost frontier, while state‐owned commercial banks undertake the least sophisticated technology. Moreover, the results of the upward trend in the technology gap ratio (TGR) and in metafrontier cost efficiency support that a more open financial market is able to enhance banking efficiency. As for the role of environmental conditions, off‐balance sheet items, non‐performing loans, and financial market structure significantly impact the TGRs of different bank types.

From scratch to efficiency gains after a financial crisis? A tale of a restructured banking system

We study the efficiency of the Argentine banking system after the 2001–2002 crisis. The financial system had to be restructured from scratch and recovered jointly with the economy, but its productivity and average cost levels have been stagnant since 2007. The analysis includes efficiency frontier estimations for retail banks and a comparison of subsamples for different categories of banks for the period 2005–15. We try to determine whether public banks are more efficient than private ones, whether privatized are more efficient than always private, as well as national versus foreign entities. Our findings show a modest average efficiency of the system and quite similar efficiency rankings for the different groups of banks. On average, public tend to be slightly more cost efficient than private, and national are slightly more efficient than foreign.     

Impact of financial reforms on efficiency of state-owned,private and foreign banks in Pakistan

This article uses a unique bank level data from 1991 to 2000 and evaluates how financial reforms affect banking efficiency of domestic and foreign banks in Pakistan. The results suggest that banking efficiency falls during initial reform period when banks adjust to enhanced competition but increases in more advanced stages of reform. While in general foreign and private banks show superior efficiency and factor productivity than do state-owned banks, the relative performance of foreign banks worsens after the consolidation stage of the financial reforms is over. We show the importance of link between bank size, asset quality and bank branches with efficiency indexes and also note that every 10% increase in share of nonperforming to total loans decreases banking efficiency by 6 to 10%.     

Determinants of the allocative,cost and scope efficiencies of Indian banks

ABSTRACT

This study aims to investigate the impact of competition on determinants of allocative, scope and cost efficiencies of Indian scheduled commercial banks (SCBs). Specifically, the study, analyzes the impact of the second round of licensing on the efficiency of Indian SCBs. This is the first paper to measure scope efficiency of Indian banks and analyze its determinants. A two-stage analysis is performed on a balanced panel dataset of Indian SCBs for the period 1999–2016. In the first stage, the allocative, cost and scope efficiencies for each bank are estimated following the data envelopment analysis approach. In the second stage, internal determinants of the stated efficiency measures are estimated following the system of the generalized method of moments approach. The findings suggest that competition has not resulted in enhancing the efficiency of Indian SCBs. Among factors that can influence efficiency, it is seen that size does matter. Larger banks can enhance the efficiency of SCBs. It is also seen that having more foreign banks improves the overall efficiency of SCBs. However, before embarking on further rounds of licensing, the study posits that market-driven correction to succeed, it is imperative to address sunspots in the form of investor or borrower repression.     

Banking reforms,performance and risk in China

We investigate the impact of the banking reform started from 2005 on ownership structures in China on commercial banks’ profitability, efficiency and risk over the period 2000–2012, providing comprehensive evidence on the impact of banking reform in China. We find that banks on average tend to have higher profitability, lower risk and lower efficiency after the reforms, and the results are robust with our difference-in-difference approach. Our results also show that the Big 5 state-owned banks (SOCB) underperform banks with other types of ownership when risk is measured by non-performing loans (NPLs) over the entire study period but tend to have fewer NPLs than other banks during the post-reform period. Our results provide some supporting evidence on the ongoing banking reforms in China, suggesting that attracting strategic foreign investors and listing SOCBs on stock exchanges appear to be effective ways to help SOCBs deal with the problem of NPLs and manage their risk.     

Privatization,foreign bank entry and bank efficiency in Croatia: a Fourier-flexible function stochastic cost frontier analysis

Using bank balance sheet data for Croatia for 1994 to 2000, this study estimates a Fourier-flexible frontier cost function. Specification tests indicate that the stochastic frontier model with a Fourier-flexible form with a truncated normal distribution of the inefficiency term allowing for time varying cost efficiency is preferred. The results show that new private and privatized banks, contrary to some expectations, are not the most efficient banks through most of the period. Privatization also does not seem to have an immediate effect on improved efficiency. However, better cost efficiency is associated with a lower likelihood of failure, suggesting that better risk management and better cost management are signs of better management in general. Finally, foreign banks have substantially better efficiency scores than all categories of domestic banks.     

Banking efficiency in transition economies

An increasing share of the banking sector is controlled by foreign capital in the majority of transition countries. To analyse the effects of this trend on the performance of the banking sector in these countries, this study conducts a comparative analysis of the performance of foreign‐owned and domestic‐owned banks operating in the Czech Republic and Poland. We use the stochastic frontier approach to compute cost efficiency scores. Following Mester (1996 ), financial capital is included in the cost frontier model to control for risk preferences. Our finding is that on average foreign‐owned banks are more efficient than domestic‐owned banks. We conclude, however, that this advantage does not result from differences in the scale of operations or the structure of activities.     

Productivity and efficiency of Vietnamese banking system: new evidence using Färe-Primont index analysis

This article aims to provide a clearer view on the recent evolutions of the Vietnamese banking system that can be useful to public authority when taking restructuring decisions. This article focuses on the evolution of productivity of Vietnamese banks over the period 2008 to 2012, and on the evolution of the different components of this productivity: technical change, pure technical efficiency and mix and scale efficiency. The methodology draws from very recent developments in index theory in the design of multiplicative-complete economically ideal indexes, using Färe-Primont productivity indexes to measure productivity. This methodology is applied to a balanced panel of Vietnamese banks. The results complement observations usually made on the recent development of the Vietnamese banking system. They show that the State Bank of Vietnam’s restructuring policy cannot focus only on either the insufficient size of banks or a better management of these banks in terms of the mix of outputs. Both must be considered simultaneously, not only through bank mergers but also in setting management criteria in line with criteria defined internationally.     

The determinants of banking efficiency in Hong Kong 2004-2014

The cost efficiency of the Hong Kong Banking sector over the period 2004–2014 is estimated by data envelopment window analysis. A second stage regression analysis finds that bank size and GDP growth are positively associated with efficiency, whereas revenue diversification and inflation are associated with lower efficiency. Stock exchange listing status is associated with lower efficiency but no clear relationship between measures of market structure and efficiency is found.     

Cost and learning efficiency drivers in Australian schools: a two-stage network DEA approach

This article explore performance issues in Australian public schools, using a two-stage DEA network model, which accounts simultaneously for both cost and learning efficiency levels. In the cost efficiency stage, different types of expenses and investments are employed to support a given number of students, teachers and administrative staff. In the learning efficiency stage, these groups of individuals help to produce important outputs related to performance in student tests and school rankings. Results indicate that Australian public schools are heterogeneous. Policy implications are also discussed.

Bank efficiency in South‐Eastern Europe

This study examines the cost and profit efficiency of banking sectors in six transition countries of South‐Eastern Europe over the period 1998–2008. Using a stochastic frontier approach, our analysis reveals that the average cost efficiency of South‐Eastern European banks is 68.59 percent, and the average profit efficiency is 53.87 percent. Regressions on the determinants of bank efficiency show that foreign banks are characterized by higher profit efficiency but lower cost efficiency, and government‐owned banks are associated with lower profit efficiency than domestic private banks. However, the efficiency gap between foreign‐, domestic private‐ and government‐owned banks narrows over time. We also find that the market power of a bank has a positive association with both cost and profit efficiency. Institutional development, proxied by progress in banking regulatory reforms, privatization and enterprise corporate governance restructuring, also has a positive impact on bank efficiency.

The Impact of Foreign Entry on Chinese Banks

Utilizing hand collected data concerning foreign ownership in the Chinese banking sector, we examine whether foreign ownership improves the efficiency of Chinese banks. Foreign banks tend to provide cooperation in retail banking rather than in corporate or private banking. We find no robust evidence of an improvement in the efficiency of an average bank that receives foreign strategic investments. However, the bank cost and profit efficiency significantly improve when foreign strategic investments provide retail banking and internal control assistance respectively to local banks. These findings suggest that foreign investment improves local bank efficiency when it transfers technologies that are lacking in local banks.
