Bad luck or bad management? Emerging banking market experience

A large number of bank failures occurred in transition countries during the 1990s and at the beginning of the 2000s. These were related to increases in non-performing loans and deteriorated cost efficiency of banks. This paper addresses the question of the causality between non-performing loans and cost efficiency in order to examine whether either of these factors is the deep determinant of bank failures. We extend the Granger-causality model developed by [Berger, A., DeYoung, R., 1997. Problem loans and cost efficiency in commercial banks. J. Banking Finance 21, 849–870] by applying GMM dynamic panel estimators on a panel of Czech banks between 1994 and 2005. Our findings support the bad management hypothesis, according to which deteriorations in cost efficiency precede increases in non-performing loans. Banking supervisors should consequently focus on enhanced cost efficiency of banks in order to reduce the likelihood of bank failures in transition countries.     

The marketability of bank assets, managerial rents and banking stability

Financial innovation and greater information availability have increased the tradability of bank assets and have reduced banks’ dependence on individual bank managers. We show that this can have two opposing consequences for banking stability. First, the hold-up problem between bank managers and shareholders becomes less severe. Consequently, banks’ capital structure needs to be less concerned with disciplining the management. Deposits – the most effective disciplining device – can be reduced, increasing banks’ resilience to adverse return shocks. However, limiting the hold-up problem also diminishes bank managers’ rents, reducing their incentives to properly monitor and screen borrowers, with adverse implications for asset quality. Thus, the default risk of banks does not necessarily decline. We argue that this delivers a novel explanation for the origin of the recent subprime crisis.     

On the independence of assets and liabilities: Evidence from U.S. commercial banks, 1990–2005

Traditional asset–liability management techniques limit banks’ abilities to structure their balance sheets—but more recently, financial innovations have allowed banks the chance to manage interest rate risk without constraining their asset–liability choices. Using canonical correlation analysis, we examine how the relationships between asset and liability accounts at U.S. commercial banks changed between 1990 and 2005. Importantly, we show that asset–liability linkages are weaker for banks that are intensive users of risk-mitigation strategies such as interest rate swaps and adjustable loans. Perhaps surprisingly, we find that asset–liability linkages are stronger at large banks than at small banks, although these size-based differences have diminished over time, both because of increased asset–liability linkages at small banks and decreased linkages at large banks.     

Differential impact of Korean banking system reforms on bank productivity

We study the impact of banking system reforms during a crisis following a period of undisciplined lending. Regulatory changes aimed at strengthening the banks’ capital structure and risk management practices do not have a uniform impact on bank productivity, but rather favor financially sound or strategically privileged banks. We present evidence documenting the differential impact of regulatory reforms on Korean commercial bank productivity over the period 1995–2005. Average technical efficiency of banks decreased during the financial crisis of 1997–1998. It improved following the subsequent bank restructuring and continued to improve through 2005. The capital adequacy ratio is positively associated with banks’ technical efficiency. The non-performing loans ratio is negatively associated with technical efficiency. Both relationships are accentuated during the crisis but attenuated after the reforms.     

Characteristics determining the efficiency of foreign banks in Australia

The factors determining foreign bank efficiency are investigated using a three stage research method. It is found that host market incumbency reduces efficiency of foreign banks in Australia, resulting in over use of inputs. Factors underlying the limited global advantage hypothesis of Berger et al. [Berger, Allen N., DeYoung, Robert, Genay, Hesna, Udell, Gregory F., 2000. Globalisation of financial institutions: Evidence from cross-border banking performance. Brookings-Wharton Papers on Financial Service 3, 23–120] are identified, in that nationality specific factors represented by dummy variables are not significant once other relevant effects are controlled for. Parent profitability is not found to result in increased host nation efficiency, while parent credit rating effects are mixed. Some evidence is presented that banks from more financially sophisticated nations are more efficient. The implications of these results are explored from the perspectives of bank management and bank regulators.     

Diversification and Value-at-Risk

A pervasive and puzzling feature of banks’ Value-at-Risk (VaR) is its abnormally high level, which leads to excessive regulatory capital. A possible explanation for the tendency of commercial banks to overstate their VaR is that they incompletely account for the diversification effect among broad risk categories (e.g., equity, interest rate, commodity, credit spread, and foreign exchange). By underestimating the diversification effect, bank’s proprietary VaR models produce overly prudent market risk assessments. In this paper, we examine empirically the validity of this hypothesis using actual VaR data from major US commercial banks. In contrast to the VaR diversification hypothesis, we find that US banks show no sign of systematic underestimation of the diversification effect. In particular, diversification effects used by banks is very close to (and quite often larger than) our empirical diversification estimates. A direct implication of this finding is that individual VaRs for each broad risk category, just like aggregate VaRs, are biased risk assessments.     

Joint size and ownership specialization in bank lending

During the period 1996–2003 consolidation reduces the size diversity of Spanish banks but diversity in ownership forms increases as savings banks and cooperatives gain market share. This paper examines the implications of these structural changes in Spanish credit markets in terms of banks’ specialization (large or small borrowers, relational or transactional lending) and consequent credit availability for small and opaque firms. We find that size-of-the-borrower/size-of-the-bank specialization follows a different pattern in savings banks than in commercial banks, suggesting lower organizational diseconomies of size in the former than in the latter, which helps to explain the increase in ownership diversity over time. We also find that savings banks and cooperatives specialize relatively more in relational lending than commercial banks so ownership diversity assures funding for small firms even if bank consolidation continues.     

Does IT investment improve bank performance? Evidence from Europe

This paper investigates whether investment in information technology (IT) – hardware, software and other IT services – influences the performance of banks. Using a sample of 737 European banks over the period 1995–2000 we analyse whether IT investment is reflected in improved performance (measured using both standard accounting ratios and cost and alternative profit efficiency measures). Despite banks being major investors in IT we find little relationship between total IT investment and improved bank profitability or efficiency indicating the existence of a profitability paradox. However, the impact of different types of IT investment (hardware, software and services) on banks’ performance is heterogeneous. Investment in IT services from external providers (consulting services, implementation services, training and education, support services) appears to have a positive influence on accounting profits and profit efficiency, while the acquisition of hardware and software seems to reduce banks’ performance.     

Cost efficiency of the banking industry in the South Eastern European region

This paper analyses cost efficiency in the banking sector of six South Eastern European countries over the period 1998–2003. A stochastic frontier approach, incorporating firm-specific and country-related variables, indicates a generally low level of cost efficiency, with significant inefficiency differences among countries. Foreign banks and banks with higher foreign bank ownership involvement are associated with lower inefficiency. Furthermore, we observe a negative correlation of cost inefficiency with bank capitalization and firm market share, and a positive one with the fraction of loans in the asset portfolio.     

The cost of being late? The case of credit card penalty fees

This paper is the first in the literature to examine the determinants of US credit card penalty fees. Many critics of credit card fees – including a number of US Senators – have argued that credit card penalty fees reflect banks’ market share. Using a unique data set we find that fees are increasing in customer risk which supports the position of defenders of penalty fees, such as banks. However, our finding that fees are increasing in a bank's market share is consistent with the concerns expressed by politicians and regulators. We also find card penalty fees are direct substitutes for card interest rates.     

Schumpeterian competition and efficiency among commercial banks

In this paper, we aim to fill the gap in the banking literature by quantifying the impact that the Schumpeterian competition mode – i.e. competition through the launch of new products (or new varieties of products) – has on the cost and profit efficiency of a sample of commercial banks based in the United Kingdom. We estimate both a cost and an alternative profit frontier on an unbalanced panel of UK commercial banks over the period 2001–2012. The intensity of competition through product innovation is proxied by the trademark intensity (i.e. the ratio between the number of trademarks registered in a given year by all the commercial banks – net of the trademarks registered by the bank under observation – and the employment in the sector) in the commercial banking sector. Our results show that the (lagged) trademark intensity in the commercial banking sector does affect negatively the mean cost and profit efficiency in the sector but there is evidence that as trademark intensity increases in the sector, commercial banks react by improving their cost and profit efficiency.     

Aggregate liquidity shortages, idiosyncratic liquidity smoothing and banking regulation

This paper develops a model of banking fragility driven by aggregate liquidity shortages. Inefficiencies arise from a failure of the interbank market to smooth the available liquidity in such a shortage. We find that a standard lender of last resort policy is ineffective in restoring efficiency as it leads to offsetting changes in the banks’ supply of liquidity. In contrast, subsidizing the purchase of assets from troubled banks increases welfare by improving the banks’ liquidity holdings. The first best, however, is achieved by redistributing existing liquidity from healthy to troubled banks in a crisis.     

Liquidity risk and syndicate structure

We decompose syndicated loan risk into credit, market, and liquidity risk and test how these shape syndicate structure. Commercial banks dominate relative to non-banks in loan syndicates that expose lenders to liquidity risk. This dominance is most pronounced when borrowers have high levels of credit or market risk. We then tie commercial banks’ advantage in liquidity risk to access to transactions deposits by comparing investments across banks. The results suggest that risk-management considerations matter most for participants relative to lead arrangers. Links from transactions deposits to liquidity exposure, for instance, are more than 50% larger at participants than at lead arrangers.     

Trademarking status and economic efficiency among commercial banks: Some evidence for the UK

As competition in the banking sector has intensified over the last two decades, commercial banks have started to use trademarks to differentiate their products and services from those offered by their competitors. Less clear are the implications of the trademarking activities on the commercial banks’ performance. In this paper, we compare the cost and profit efficiency of trademarking and non-trademarking banks in the UK, over the period 2001–2013 using stochastic frontier methods. We use Propensity Score Matching techniques to identify a sample of non-trademarking banks which share the same characteristics as the trademarking banks to ensure that variations in the efficiency between the commercial banks in our sample can be attributed to their trademarking status only. We then explicitly test the hypothesis that trademarking and non-trademarking banks share the same cost and profit frontiers. We cannot reject the hypothesis of a common cost and profit frontier. We also find that trademarking banks tend to be more profit efficient than non-trademarking banks while there is no significant difference between the cost efficiency scores of trademarking and non-trademarking banks.     

Deregulation,technological change,and the business-lending performance of large and small banks

According to DeYoung et al. [Journal of Financial Services Research, 2004] deregulation and technological change has divided the US banking industry into two primary size-based groups: very large banks, specializing in the use of “hard” information to make standardized loans and smaller banks, specializing in the use of “soft” information and relationship development to make non-standardized loans. We evaluate business-lending performance for small and large banks over the 1993–2001 period. Small business lending by small banks is characterized by relationship development and non-standardized loans. Consistent with DeYoung et al.'s model, we find that, after controlling for market concentration, cost of funds, and a variety of other factors that might influence yields, smaller banks perform better than larger banks in the small business lending market. However, larger banks appear to have the advantage in credit card lending, a market characterized by impersonal relationships and standardized loans. Interestingly, we find evidence that larger banks have been making inroads in the market for the smallest business loans, a result consistent with the use of credit scoring by large banks to make very small business loans [Berger et al., Journal of Money, Credit, and Banking, 2004].     

On the importance of retail banking relationships

We use proprietary data to analyze the importance of retail banking relationships to commercial banks and their depositors when banks underwrite securities. We find lead underwriters’ retail customers benefit as they demand and end up with significantly more of the highly underpriced issues. We find it is actual underpricing beyond that predicted by grey markets that drive the differential demand from the lead bank retail clientele, suggesting that banks pass on information about underpriced initial public offerings to their retail depositors. We analyze banks’ incentives for such behavior and find evidence of banks benefiting through retail cross-selling—both brokerage accounts and consumer loans increase significantly.     

The false prosperity and promising future: Effects of data resources on bank efficiency

This study investigates the impact of data resources on bank efficiency. Based on data management theory, we measure bank data resources and find that higher data resources are associated with lower cost efficiency using data on Chinese banks over the period 2013 to 2019. However, data resources have no significant impact on profit efficiency. We discover that data resources reduce cost efficiency possibly due to increased overheads and decreased capital adequacy ratio. Furthermore, we conclude that emerging data technologies can reduce the cost burden of data resources on commercial banks, resulting in synergistic technical benefits. The findings are of timely policy importance and practical relevance for regulators, policy-makers, and bank managers. Our main results hold for a battery of endogeneity and robustness tests.     

Regional economic development,strategic investors,and efficiency of Chinese city commercial banks

We investigate the effect of strategic investors on bank efficiency in the context of regional economic development. The data on Chinese city commercial banks operating regionally are well-suited for the study. Our findings suggest that strategic investors significantly increase efficiency in Chinese city commercial banks, while the effect of strategic investors on the efficiency of Chinese city commercial banks is negatively correlated to the level of regional economic development. The negative correlation of the effect of strategic investors on Chinese city commercial banks’ efficiency with regional economic development may be explained by the mix of local official promotion system and city commercial banks’ governance structure.

通过随机前沿模型(SFA)和超越对数函数,本文建立了计算商业银行成本、利润效率的随机前沿模型。基于1994-2010年间我国14家商业银行相应数据的计算结果我们发现:1994-2010年间商业银行成本、利润效率经历了明显的改进趋势,且国有控股大型商业银行的成本、利润效率要显著低于股份制商业银行。无效率函数的分解结果中,资本充足率的提高和不良贷款率的降低将会对商业银行的成本、利润效率产生明显的积极影响,而外资持股比例的增加也会显著地提升商业银行的成本、利润效率。最后,本文得出了相应的结论和政策建议。     

Incorporating risk input into the analysis of bank productivity: Application to the Taiwanese banking industry

This study reappraises banks’ productivity by using 42 Taiwanese banks during 1999–2007 as observations. It introduces an input-oriented generalized metafrontier Malmquist productivity index (I-gMMPI), while considering the latent effect of risk-taking behavior in the analytic framework. We learn that public and private banks should face separate short-term technological frontiers, while the econometric model considering risk input can portray banks’ operating frontiers better. Moreover, neglecting the influence of risk input would bring about distortions of efficiency, technology and TFP dynamic estimations for banks; meanwhile, the degree of scale economies would also be overestimated. The paper concludes that neglecting the risk-taking essence in bank performance evaluation is equal to allowing banks to barter risk-bearing as the term for further output growth. Consequently, the potential cost is that banks may excessively aggrandize their scales of business, implying the possibility of another financial crisis.
