The Skill Profile of Central Bankers and Supervisors

Using a new database covering some 91 supervisory agencies, this paper examines how important various skilled experts are in the supervisory process and the relative usage of different kinds of such experts. We seek to explore what kind of perspective supervisors in different institutional settings may adopt: a macro-oriented perspective or a more micro-approach? The answer to this question is relevant, as there is evidence that many financial crises have been macro-induced.It is found that central banks employ more economists and fewer lawyers in their supervisory/financial stability wing than non-centralbank supervisory agencies. This result would indicate that an institutional setting with direct or indirect central bank involvement is more likely to produce a macro-approach. Next, there are significant economies of scale in financial supervision, though this can be measured by several alternative variables (e.g., the relative scale of bank intermediation). Finally, there do not appear to be major economies of scope. A more complex financial system with a well-developed stock market would need both more supervisors as well as more skilled ones.

Who said large banks don’t experience scale economies? Evidence from a risk-return-driven cost function

The Great Recession focused attention on large financial institutions and systemic risk. We investigate whether large size provides any cost advantages to the economy and, if so, whether these cost advantages are due to technological scale economies or too-big-to-fail subsidies. Estimating scale economies is made more complex by risk-taking. Better diversification resulting from larger scale generates scale economies but also incentives to take more risk. When this additional risk-taking adds to cost, it can obscure the underlying scale economies and engender misleading econometric estimates of them. Using data pre- and post-crisis, we estimate scale economies using two production models. The standard model ignores endogenous risk-taking and finds little evidence of scale economies. The model accounting for managerial risk preferences and endogenous risk-taking finds large scale economies, which are not driven by too-big-to-fail considerations. We evaluate the costs and competitive implications of breaking up the largest banks into smaller banks.     

Consolidation and efficiency in the financial sector: A review of the international evidence

In response to fundamental changes in regulation and technology, the financial industry is undergoing an unprecedented wave of consolidation. A growing body of empirical literature measures the efficiency gains from mergers and acquisitions; however there is little sense of how the results might depend on the country, industry and time period analyzed. In this paper we review critically works that cover the main sectors of the financial industry (commercial and investment banks, insurance and asset management companies) in the major industrialized countries over the last 20 years, searching for common patterns that transcend national and sectoral peculiarities. We find that consolidation in the financial sector is beneficial up to a relatively small size, but there is little evidence that mergers yield economies of scope or gains in managerial efficiency.     

Consequences of Deregulation for Commercial Banking

In recent years, many of the restrictions on banking activities adopted following the banking collapse of the 1930s have been eroded by improvements in technology and high interest rates, which led to increasing direct competition from unregulated institutions. Beginning in the 1970s, the regulatory agencies, state legislatures, and the Congress have moved to liberalize these restrictions. Based on research on economies of scale and scope, the experience of the conglomerate merger movement of the 1950s and 1960s, the observed effects of changes in state laws governing branches and holding companies, foreign experience, and experience in other industries that underwent deregulation, banking deregulation is likely to lead to reductions in the number of banks and increases in their efficiency, geographic scope, and product diversification. Such an outcome is consistent with the survival of a large number and variety of financial institutions and need not endanger the safety of the banking system.     

Correlations,business cycles and integration

Correlations and the integration of capital markets impact upon portfolio diversification. The key research question addressed in this paper is whether and to what extent business cycles and financial deregulation affect correlations and integration between the Australian and US markets. In summary, four major themes can be detected in our findings. First, correlations between the Australian and US markets are at their highest when the US is in a contractionary phase. Secondly, we are more likely to conclude that the markets are integrated in the expansionary phase of business cycles. Thirdly, we are more likely to conclude that the markets are segmented in the contractionary phase of the business cycles. Finally, we are more likely to conclude that markets are segmented prior to deregulation and integrated in the post financial deregulation period.     

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.     

Branching restrictions and banking costs

Previous research of banking costs has been limited by the choice of the functional form, irregularities in the estimated cost functions, and a failure to rigorously examine the difference between banks in branching states and banks in unit-banking states. This paper addresses these shortcomings. Banks are modelled as three-input-three-output cost minimizing firms. A three equation system is estimated using 1985 Functional Cost Analysis data. The findings indicate that banks in unit-banking states experience diseconomies of scale Banks in branching states experience diseconomies of scale at the bank level but economies of scale at the branch level. We also find evidence of economies of scope for branch-state banks but not for unit-state banks.     

On the Benefits of Concurrent Lending and Underwriting

This paper examines whether there are efficiencies that benefit issuers and underwriters when a financial intermediary concurrently lends to an issuer while also underwriting its public securities offering. We find issuers, particularly noninvestment‐grade issuers for whom informational economies of scope are likely to be large, benefit through lower underwriter fees and discounted loan yield spreads. Underwriters, both commercial banks as well as investment banks, engage in concurrent lending and provide price discounts, albeit in different ways. We find concurrent lending helps underwriters build relationships, increasing the probability of receiving current and future business.     

Efficiency and technical progress in banking Empirical results for a panel of German cooperative banks

Using 1989–1992 individual data of 757 German cooperative banks and applying the intermediation approach we specify a multi-product translog cost function for this part of the German banking industry. For all size classes moderate economies of scale can be identified. There is also evidence of economies of scope which supports the notion of universal banking. As for cost efficiency, we find that the average banks in all size classes deviate considerably from the best practice cost frontier. All banks enjoy growth of total factor productivity, which is higher for the smaller banks in the sample.     

The composite cost function and efficiency in giant Japanese banks

This study provides further empirical investigation, in the context of giant Japanese banks, of the recent claim by Pulley and Braunstein (1992, A composite cost function for multiproduct firms with an application to economies of scope in banking, Review of Economics and Statistics 74, 221–230), that their new composite model for the multiproduct cost function has important advantages over the separable quadratic, generalized translog and standard translog models. In addition to assessing the composite model's relative ability in measuring global scope and scale economies, the study also extends the P-B analysis to assess measurement of product-specific scope and scale economies, pairwise cost complementarities between outputs, changes in the marginal costs of outputs and technological change. The results appear to confirm P-B's chain. The persistent finding of scale economies for large Japanese banks is also investigated and confirmed.     

Are there any cost and profit efficiency gains in financial conglomeration? Evidence from the accession countries

Diversified banks should benefit from an efficient allocation of resources, debt coinsurance and scope economies. At the same time, critics of diversification question these advantages pointing to agency problems such as managerial entrenchment and empire building that could also lead to diversification but for the ‘wrong’ reasons. This paper sheds further light on the issue of bank diversification by taking a direct look into how efficiently financial conglomerates operate and by measuring to what extent size and other bank- and market-specific factors matter in evaluating the relationship between diversification and efficiency. We focus on banks operating in the accession countries over the period 2001–2007 and estimate their cost and alternative profit efficiencies using a data envelopment analysis estimator. The results indicate that banks suffer from relatively high cost and profit inefficiencies and that there are noticeable differences in the efficiency levels across countries. Concerning banks’ degree of diversification, we find strong evidence to suggest that more diversified institutions are more likely to be cost- and profit-efficient and that size is a key factor in explaining best practice, particularly on the profit side.     

Financial constraints of private firms and bank lending behavior

We investigate whether and how financial constraints of private firms depend on bank lending behavior. Bank lending behavior, especially its scale, scope and timing, is largely driven by bank business models which differ between privately owned and state-owned banks. Using a unique dataset on private small and medium-sized enterprises (SMEs) we find that an increase in relative borrowings from local state-owned banks significantly reduces firms’ financial constraints, while there is no such effect for privately owned banks. Improved credit availability and private information production are the main channels that explain our result. We also show that the lending behavior of local state-owned banks can be sustainable because it is less cyclical and neither leads to more risk taking nor underperformance.     

Examining the Relationships between Capital,Risk and Efficiency in European Banking

This paper analyses the relationship between capital, risk and efficiency for a large sample of European banks between 1992 and 2000. In contrast to the established US evidence we do not find a positive relationship between inefficiency and bank risk‐taking. Inefficient European banks appear to hold more capital and take on less risk. Empirical evidence is found showing the positive relationship between risk on the level of capital (and liquidity), possibly indicating regulators' preference for capital as a mean of restricting risk‐taking activities. We also find evidence that the financial strength of the corporate sector has a positive influence in reducing bank risk‐taking and capital levels. There are no major differences in the relationships between capital, risk and efficiency for commercial and savings banks although there are for co‐operative banks. In the case of co‐operative banks we do find that capital levels are inversely related to risks and we find that inefficient banks hold lower levels of capital. Some of these relationships also vary depending on whether banks are among the most or least efficient operators.     

Too Big to Be Efficient? The Impact of Implicit Subsidies on Estimates of Scale Economies for Banks

We examine whether “too‐big‐to‐fail” (TBTF) factors affect estimates of scale economies for large banks. From a standard model of bank production that does not control for any TBTF factors, we find evidence of scale economies for our sample of large banks. We then control for TBTF factors by using a measure of the “implicit subsidy” that emerges from a reduction in TBTF banks’ funding costs due to investor expectations of government support. We do this in two ways: first, we estimate scale economies from an augmented model of bank production that employs a proxy for the counterfactual price of debt that banks would face in the absence of any TBTF funding cost advantage; second, we estimate scale economies from a model of bank production that is estimated only for a sample of banks considered unlikely to be TBTF. After controlling for TBTF factors using either method, we no longer find evidence of scale economies for our sample of large banks. These results suggest that estimated scale economies for large banks are affected by TBTF factors.     

Banking Mergers: The Impact of Financial Liberalization on the Taiwanese Banking Industry

The objective of this paper is to examine the nature of the Taiwanese banking sector and to analyze the impact of financial liberalization on the Taiwanese banking industry. We present empirical evidence to show that the recent wave of bank mergers observed in other countries is also suitable for Taiwan. Based on empirical results for overall economies of scale and expansion path subadditivity, Taiwanese banks should obtain the benefit of scale economies by merging with other banks rather than expanding by opening more branches. Furthermore, we show that the Relative Market Power hypothesis—which postulates that greater market shares lead to higher profitability—finds empirical support in Taiwanese banking data after financial reforms were enacted.     

An Investigation of the Impact of Interest Rates and Interest Rate Volatility on Australian Financial Sector Stock Return Distributions

Abstract:   This paper extends the existing literature by analysing the dual impact of changes in the interest rate and interest rate volatility on the distribution of Australian financial sector stock returns. In addition, a multivariate GARCH‐M model is used to analyse the impact of deregulation on the financial institutions sector. It was found that there is a consistent inter‐temporal trade off between risk and return over the different regulatory periods. Moreover, finance corporations were found to be highly sensitive to new shocks across the financial sector and deregulation increased the risk faced by finance corporations and small banks – effectively increasing the required rate of return and explaining the continued rationalisation of these sectors. Furthermore, deregulation has changed the fundamental relationship between interest rates and large bank stock excess returns from positive in the pre‐deregulation period to negative in the post‐deregulation period. This reflects the changing institutional environment from one of controlled credit rationing to a more competitive environment.     

Do customer profiles change over time? An investigation of the success of targeting consumers of Australia’s top 10 banks – 2009 and 2011

Segmentation and targeting are cited as being a core part of marketing strategy for any organisation. This study examines whether the top 10 Australian banks have successfully managed to segment the market and target consumers with different profiles. In doing so, it compares the profiles of those banks over 2 years, 2009 and 2011, noting any changes between the years. A sample of 52?000 Australian households, from each of the 2 years, from the Roy Morgan Single Source Survey was utilised to profile users of Australia’s top 10 banks by market share. The results suggest that there has been little difference in profiles of consumers across most Australian banks. The results challenge whether financial service companies are successfully segmenting the marketplace and asks whether the Australian financial services market is simply a mass market.     

Who benefits from financial liberalization? Evidence from advanced and emerging market economies

In recent decades most countries have implemented significant reforms to foster financial liberalization. This article examines to what extent these reforms have benefited advanced economies and emerging market economies. We focus on four groups of countries: the G-7, other European countries, Latin America and East Asia over the period 1973–2006. We find evidence supporting the hypothesis that the different forms of financial liberalization affected growth differently in the four groups of countries. The main finding is that the benefits of financial liberalization are more important for advanced economies. In contrast, financial liberalization in emerging market economies has a weak positive impact on growth when its scope is limited, whereas full liberalization has been associated with slower economic growth.     

Who Benefits from Deregulating the Separation of Banking Activities? Differential Effects on Commercial Bank,Investment Bank,and Thrift Stock Returns

We analyze the deregulation impact on commercial banks, investment banks, and thrifts associated with four major events progressively integrating commercial and investment banking activities in the United States during the 1990s. We find that commercial banks are the only group to react favorably to Federal Reserve announcements relaxing firewalls and easing restrictions on commercial bank revenues from investment banking activities. These regulations primarily benefit large banks. The Bankers Trust acquisition announcement of investment bank Alex Brown is associated with increased wealth for each of the three types of financial service institutions. At the eventual deregulation of the financial services industry, with the passage of the Financial Services Modernization Act in 1999, the values of commercial banks and investment banks increase significantly although thrifts are not affected.
