Cost and Profit Efficiency of the Turkish Banking Industry: An Empirical Investigation

By employing a stochastic frontier approach, we examine the effect of bank size, corporate control, and governance, as well as ownership, on the cost (input) and alternative profit (input-output) efficiencies of Turkish banks. We find that the average profit efficiency is 84% for Turkish banks. The oligopolistic nature of the Turkish banking industry has contributed to less than optimal competition in the loan market and deposit markets. Our results indicate that the degree of linkage between cost and profit efficiency is significantly low. This suggests that high profit efficiency does not require greater cost efficiency in Turkey, and that cost in efficient banks can continue to survive in this imperfect market, where profit opportunities are abundant for all types and sizes of banks. Accordingly, our results indicate that the different sizes of banks have capitalized these opportunities equivalently.     

In search of a rational foundation for the massive IT boom in the Australian banking industry: Can the IT boom really drive relationship banking?

Information technology (IT) is meant to improve bank performance by lowering operational costs and improving the process of financial intermediation of banks. However, the empirical evidence has failed to reach a consensus on the precise effects of IT on bank performance as some find evidence to concur with the Solow Paradox, while others contradict this paradox. The heterogeneity in the quality of banking services is partly responsible for the inconsistency in the findings. To sidestep the issue of heterogeneity, we consider the top-tier Australian banks for which the quality of banking services is homogeneous. Applying the dynamic panel data methodology, i.e., panel autoregressive distributed lag (panel ARDL) and cross-sectionally augmented panel ARDL (CS-ARDL) models, we investigate the effect of IT on the cost and profit efficiency frontiers of the top-tier Australian banks during 2000–2019. We unequivocally establish that the frontiers of bank profits rise due to the adoption and diffusion of IT investment, contradicting the assumed failure of IT to adequately collect soft information in the banking industry. Furthermore, we find that the cost frontiers have risen, driven by the IT boom. Hence, there is evidence that despite increases in operational inefficiency, IT has shifted the profit frontiers up by enhancing relationship banking in Australia.     

How Does Cross‐Border Activity Affect EU Banking Markets?

Cross‐border activity in the EU is widely viewed as a necessary condition for the implementation of a single banking market and therefore as a positive factor for the enhancement of competition and cost performance in the region. In this paper, we analyse the relevance of this view by investigating whether cross‐border activity really promotes competition and cost efficiency in EU banking markets. We also consider the potential role of a bank's mode of entry by comparing existing domestic banks that foreign banks take over (mergers and acquisitions) with new branches created by foreign banks, often through subsidiaries (greenfield operations). We consider the impact of cross‐border banks on cost efficiency (measured by the stochastic frontier approach), profitability (assessed through return on assets) and competition (measured by the Lerner index). We find that greenfield banks enhance cost efficiency and competition, while mergers and acquisitions hamper competition and cost efficiency. Therefore, our results suggest that EU authorities should promote only greenfield banks rather than all cross‐border entries.     

Evaluating the state of competition of the Greek banking industry

The present paper uses three different New Empirical Industrial Organization (NEIO) approaches (Panzar–Rosse, Bresnahan–Lau and Hall–Roeger models) to investigate competitive conditions in the Greek banking sector over the period 1995–2004. One important event which has taken place in the Greek banking industry, especially after 1998, is a wave of mergers and acquisitions. This study also measures and compares the degree of banking competition in two sub-periods, 1995–1998 and 1999–2004, in order to investigate the effect of mergers and acquisitions on the competitive structure of Greek banking. The empirical results of the three models indicate a shift from competitive to non-competitive conditions when moving from the first to the second sub-period. This finding suggests that mergers and acquisitions have affected the level of completion of Greek banking, rendering the industry less competitive. Furthermore, taking into consideration the negative effects of mergers and acquisitions on technical efficiency and the total factor productivity of Greek banking (Rezitis, 2008), the empirical findings of the present study provide some indications that one of the outcomes of the Greek banks’ merging activities, at least in the short run, might be to attain market power and thus higher profits, rather than higher efficiency and lower costs.     

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.     

The impact of banking regulations on banks' cost and profit efficiency: Cross-country evidence

This paper uses stochastic frontier analysis to provide international evidence on the impact of the regulatory and supervision framework on bank efficiency. Our dataset consists of 2853 observations from 615 publicly quoted commercial banks operating in 74 countries during the period 2000-2004. We investigate the impact of regulations related to the three pillars of Basel II (i.e. capital adequacy requirements, official supervisory power, and market discipline mechanisms), as well as restrictions on bank activities, on cost and profit efficiency of banks, while controlling for other country-specific characteristics. Our results suggest that banking regulations that enhance market discipline and empower the supervisory power of the authorities increase both cost and profit efficiency of banks. In contrast, stricter capital requirements improve cost efficiency but reduce profit efficiency, while restrictions on bank activities have the opposite effect, reducing cost efficiency but improving profit efficiency.     

Bank Mergers,REIT Loan Pricing and Takeover Likelihood

The impact of bank mergers on Real Estate Investment Trust (REIT) loan pricing and takeover likelihood is assessed. REITs that lose their primary banking relationship due to bank mergers pay higher interest rates on future borrowings. Bank consolidation reduces bank competition for REIT loans which affects loan pricing. Moreover, based on randomly matched samples of REITs, the results imply that firms losing their agent banks due to bank mergers and those with limited access to bank debt are more likely to be acquired while REITs associated with acquiring banks are more likely to acquire other firms. Additional analysis of the 92 merged REITs reveals that 33% of the target REITs’ banks are merged with their REIT acquirers’ banks prior to the REIT mergers while 67% of the target REITs share at least one major bank with their acquirer.     

改进的效率测算模型、影子银行与中国商业银行效率

商业银行及其效率的高低是金融供给侧结构性改革的关键环节,而可以压缩的“坏”投入和影子银行对商业银行效率产生重要影响。本文首次建立理论模型并分析影子银行影响商业银行效率的路径;方法上,同时区分投入和产出的“好”或“坏”,拓展只区分产出的“好”或“坏”的效率测算模型;实证上,首次测算并分析“坏”投入、影子银行业务对商业银行利润、风险和效率的影响。结果表明:理论上,影子银行会同时增加风险承担和利润,但无法确定经风险调整后的利润增加能否提升效率;只区分产出的模型高估了效率,尤其是显著高估四大行和股份制商业银行第一阶段的效率,大型商业银行依靠网点的扩张不利于效率的提升;影子银行业务提升了四大国有银行尤其是股份制银行的效率,但对中小型商业银行效率影响较小。总的来看,压缩“坏”投入和规范影子银行是增加有效金融供给、优化金融供给结构和提升银行效率的重要途径。     

The Competitive Dynamics of Geographic Deregulation in Banking: Implications for Productive Efficiency

Deregulation of geographic restrictions in banking over the past 20 years has intensified both potential and actual competition in the industry. The accumulating empirical evidence suggests that potential efficiency gains associated with consolidating banks are often not realized. We evaluate the impact of this increased competition on the productive efficiency of non-merging banks confronted with new entry in their local markets and find that the incumbent banks respond by improving cost efficiency. Thus, studies evaluating the impact of bank mergers on the efficiency of the combining parties alone may be overlooking the most significant welfare-enhancing aspect of merger activity.     

Governance,efficiency and risk taking in Chinese banking

We employ a hand-collected unique dataset on banks operating in China between 2003 and 2011 to investigate the impact of board governance features (size, composition and functioning) on bank efficiency and risk taking. Our evidence suggests that board characteristics tend to have a greater influence on banks' profit and cost efficiency than on loan quality. We find that the proportion of female directors on the board appears not only to be linked to higher profit and cost efficiency but also to lower traditional banking risk. Similarly, board independence is associated with higher profit efficiency of banks; while the opposite is found for executive directors and in the presence of dual leadership of the CEO/chairperson. Among the control variables, we found that liquidity negatively affects profit and cost efficiency, while positively affecting risk. Interestingly, we find some evidence of an incremental effect of specific board characteristics on efficiency for banks with more concentrated ownership structures and state-owned institutions; while for banks with CEO performance-related pay schemes the effect on efficiency when significant is usually negative. Our results offer useful insights to policy makers in China charged with the task of improving the governance mechanisms in banking institutions.     

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.     

Post‐merger strategy and performance: evidence from the US and European banking industries

The banking industry has one of the most active markets for mergers and acquisitions. However, little is known about the type of operational strategies adopted by banking firms in the years following a deal. For a sample of bidding banks in the USA and Europe, this study compares the design and performance implications of different post‐merger strategies in both geographical regions. Using accounting data, we show that European banks pursue a cost‐cutting strategy by increasing efficiency levels vis‐à‐vis non‐merging banks and by cutting back on both labour costs and lending activities. US banks, on the other hand, raise both interest and non‐interest income in the post‐merger period.     

商业银行效率演进趋势及结构特征透析

应用随机边界方法（SFA）,本文对中国16家商业银行1994至2006年的成本/利润效率情况进行了测度。估计结果表明,样本期内中国商业银行成本/利润效率水平总体上均呈升势,股份制银行的表现均要优于国有银行,在成本方面这种优势在不断缩小,而在利润方面则没有明显的变化趋势。我们讨论的一个重要含义是：在经济的全面国际化和市场化背景下,革除行业准入上的制度壁垒、放松业务领域上的分割限制是提高中国商业银行盈利能力的重中之重。     

The identification of acquisition targets in the EU banking industry: An application of multicriteria approaches

In this paper we develop classification models for the identification of acquisition targets in the EU banking industry, incorporating financial variables that are mostly unique to the banking industry and originate from the CAMEL approach. A sample of 168 non-acquired banks matched with 168 acquired banks is used over the period 1998-2002, covering 15 EU countries. We compare and evaluate the relative efficiency of three multicriteria approaches, namely MHDIS, PAIRCLAS, and UTADIS, with all models developed and tested using a 10-fold cross validation approach. We find that the importance of the variables differs across the models. However, on the basis of univariate test and the results of the models we could state that in general after adjusting for the country where banks operate, acquired banks are less well capitalized and less cost and profit efficient. The results show that the developed models can achieve higher classification accuracies than a naïve model based on random assignments. Nevertheless, there is fair amount of misclassification that is hard to avoid given the nature of the problem, showing that as in previous studies for non-financial firms, the identification of acquisitions targets in banking is a difficult task.     

The Effects of Banking Mergers on Loan Contracts

This paper studies the effects of banking mergers on individual business borrowers. Using information on individual loan contracts between banks and companies, I analyze the effect of banking consolidation on banks' credit policies. I find that in-market mergers benefit borrowers if these mergers involve the acquisition of banks with small market shares. Interest rates charged by the consolidated banks decrease, but as the local market share of the acquired bank increases, the efficiency effect is offset by market power. Mergers have different distributional effects across borrowers. When banks become larger, they reduce the supply of loans to small borrowers.     

Bank efficiency in the new European Union member states: Is there convergence?

We employ the stochastic frontier approach and estimate a common frontier in order to examine cost and profit efficiency in the banking systems of the ten new European Union member states over the period 1998-2003. The results indicate a generally low level of cost and an even lower level of profit efficiency, whilst we do not observe marked differences of inefficiency scores across countries. Foreign banks outperform both state-owned and domestic private-owned banks in terms of profit efficiency, though results are less clear in the case of cost efficiency. In addition, β- and σ-convergence criteria indicate some convergence in cost efficiency across the new member states, yet no convergence appears to have been achieved in terms of profit efficiency.     

The efficiency and the conduct of European banks: Developments after 1992

We assess the efficiency of the European banking sector in the 5-year period following the implementation of the Second Banking Directive of the European Union (EU). We first determine the degree of cost efficiency of EU banks in 1993-1997. After that, we explore to what extent efficient European banks are managed differently than their inefficient peers. Our datasets comprise 5 years of observations on 1347 savings and 873 commercial banks. We use the new recursive thick frontier approach (RTFA) method to establish our results. We find that structural factors, such as technological progress or increased bank competition, have lowered the cost base of banks by about 5% annually during the sample period. Managerial inability to control costs (X-inefficiency) is with 17-25% the main source of bank inefficiency in the EU. Managerial efficiency varies a great deal within Europe, and there seems to be no tendency towards convergence. We find that small savings banks can exploit economies of scale. The EU savings bank sector would cut costs by about 3% if small savings banks merged.     

The efficiency effects of bank mergers: An overview of case studies of nine mergers

This paper summarizes nine case studies, by nine authors, on the efficiency effects of bank mergers. The mergers selected for study were ones that seemed relatively likely to yield efficiency gains. That is, they involved relatively large banks generally with substantial market overlap, and most occurred during the early 1990s when efficiency was getting a lot of attention in banking. All nine of the mergers resulted in significant cost cutting in line with premerger projections. Four of the nine mergers were clearly successful in improving cost efficiency but five were not. It is not possible to isolate specific factors from these mergers that are most likely to yield efficiency gains, but the most frequent and serious problem was unexpected difficulty in integrating data processing systems and operations.

Merger and acquisitions in South African banking: A network DEA model

Banking in South Africa is known for its small number of companies that operate as an oligopoly. This paper presents a strategic fit assessment of mergers and acquisitions (M&A) in South African banks. A network DEA (Data Envelopment Analysis) approach is adopted to compute the impact of contextual variables on several types of efficiency scores of the resulting virtual merged banks: global (merger), technical (learning), harmony (scope), and scale (size) efficiencies. The impact of contextual variables related to the origin of the bank and its type is tested by means of a set of several robust regressions to handle dependent variables bounded in 0 and 1: Tobit, Simplex, and Beta. The results reveal that bank type and origin impact virtual efficiency levels. However, the findings also show that harmony and scale effects are negligible due to the oligopolistic structure of banking in South Africa.
