IT use,productivity, and market power in banking

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.     

Bank fund reallocation and economic growth: Evidence from China

This paper examines bank fund reallocation and regional economic growth based on 1991–2005 provincial-level data of four state-owned commercial banks of China that practice fund reallocation nation-wide. We find no correlation between bank fund reallocation and regional economic growth or between bank loans and regional economic growth. We find, however, a positive association between bank deposits and growth. It appears economic growth leads financial development in China, not the other way around. Furthermore, as China’s market-oriented reforms deepen, fund reallocation and loans start to manifest positive effects on growth even though the banks are government owned.     

Measuring aggregate productivity growth using plant‐level data

We define aggregate productivity growth (APG) as the change in aggregate final demand minus the change in the aggregate expenditures on labor and capital. We show how to aggregate plant‐level data to this quantity and how to decompose APG into technical efficiency and reallocation components. This requires us to confront the “non‐neoclassical” features that impact plant‐level data, including plant‐level heterogeneity, the entry and exit of goods, adjustment costs, fixed and sunk costs, and market power. The APG decomposition includes one term per plant related to technical efficiency and one term for each input at each plant that is a function of the value of marginal product ‐ input price gap and that relates the reallocation of inputs to growth. We compare APG to several competing variants of productivity growth that are based only on plant‐level technical efficiency. Two simple theoretical examples illustrate that technical‐efficiency reallocation can be negatively correlated with actual APG reallocation because technical efficiency is a production concept and need not have any relation with the APG reallocation gaps. We illustrate this point empirically using panel data from manufacturing industries in Chile, where we show technical‐efficiency reallocation differs substantially from measured reallocation based on our definition of APG.     

On the optimality of bank competition policy

This study examines whether the effect of market structure on financial stability is persistent, subject to current regulation and supervision policies. The methodology of Sala-I-Martin (1997) is employed over a sample of 2450 banks operating within the EU-27 during the period 2003–2010. The results show a potential trade-off between market power and soundness, and how possible it is to regulate this trade-off above 21% markups. Financial stability appears more pronounced in markets of less concentration, where policies lean towards limited restrictions on non-interest income, official intervention in bank management and book transparency. Regulation and competition can act as substitute or complementary policies vis-à-vis a more stable financial system with less competition distortions.     

The bright side of market power in Asian banking: Implications of bank capitalization and financial freedom

Using a sample of listed banks in the Asia-Pacific region from 2000 to 2016, this paper documents that higher market power reduces risk taking but increases loan growth and performance in banking. This highlights the "bright side" of bank market power in general. However, the positive effect of market power on bank stability is more pronounced for well-capitalized banks, although their performance tends to decline, and loan growth is unaffected by market power. Hence, bank capitalization plays an important role in strengthening financial stability due to an increase in bank market power. Moreover, banks with higher market power located in countries with a lower degree of financial freedom exhibit lower riskiness, higher loan growth, and better performance. Greater control by authorities in the financial sector is essential, not only to enhance financial stability, but also to boost financial intermediation and bank performance following an increase in bank market power.     

The identification of technology regimes in banking: Implications for the market power-fragility nexus

Neglecting the existence of different technologies in banking can contaminate efficiency, market power, and other performance measures. By simultaneously estimating (i) technology regimes conditional on exogenous factors, (ii) efficiency conditional on risk management, and (iii) Lerner indices of German banks, we identify three distinct technology regimes: Public & Retail, Small & Specialized, and Universal & Relationship. System estimation at the regional level reveals that greater bank market power increases bank profitability but also fosters corporate defaults. Corporate defaults, in turn, lead to higher probabilities of bank distress, which supports the market power-fragility hypothesis.     

An examination of the effect of stock market liquidity on bank market power

This paper investigates the spillover effects of aggregate stock market liquidity on bank market power using a sample of 44 countries and 7297 individual banks from 1999 to 2014. Country-level and bank-level analysis shows that enhancement in stock market liquidity strengthens the market power of the banking sector. This relationship is more pronounced in developed market countries and in countries with common law origin, which offer better investor protection. To the best of our knowledge, this is the first paper to provide comprehensive empirical evidence of the complementary relationship between banks and stock markets, providing important policy implications for regulators.     

Asset price volatility,price markups,and macroeconomic fluctuations

A variant of the neoclassical growth model is considered to study the role of innovation, lags in technology adoption, total factor productivity TFP, and price markups as main determinants of asset price volatility. The model confers a prominent role to price markups as opposed to other macroeconomic sources of uncertainty. In the data, price markups are highly correlated with stock market values, whereas other financial measures of profitability exhibit much less volatility and are weakly correlated with stock market values.     

How do bank competition,regulation, and institutions shape the real effect of banking crises? International evidence

This paper studies the influence of bank competition on the real effect of 36 systemic banking crises in 30 countries over the 1980–2000 period and how this influence varies across countries depending on bank regulation and institutions. We find that bank market power is not on average useful for mitigating the negative real effect of a systemic banking crisis. Market power promotes higher growth during normal times in industries that are more dependent on external finance but induces a bigger reduction in growth during systemic banking crises. We also find a country-specific effect depending on bank regulation and institutions. Stringent capital requirements and poor protection of creditor rights increase the benefits of bank market power for mitigating the negative real effect of a systemic banking crisis because bank market power has a positive effect on economic growth during both crisis and non-crisis periods in these environments.     

Bank competition,concentration and EU SME cost of debt

Despite the plentiful debate on the effects of bank competition on SME access to finance and growth, only few studies have explored the impacts on SME cost of debt. This study examines how bank market power affects the credit costs of SMEs by using unique matched SME-bank data from 17 EU countries. We show that bank market power reduces the cost of debt for SMEs. Such a favorable effect is stronger for SMEs that are less informationally transparent, and in the economies subject to less credit information depth and business extent of disclosure. These findings support the Information-based Hypothesis, whereby market power motivates banks to invest in soft information acquisition and to build lending relationships to reduce information costs. In addition, we show that despite the favorable effects of relationship lending brought by bank market power, SME credit conditions worsen in a more concentrated banking market.     

Banking competition and economic growth: cross-country evidence

The aim of this paper is to analyse the effect of banking competition on industry economic growth using both structural measures of competition and measures based on the new empirical industrial organisation perspective. The evidence obtained in the period 1993–2003 for a sample of 53 sectors in 21 countries indicates that financial development promotes economic growth. The results also show that bank monopoly power has an inverted-U-shaped effect on economic growth, suggesting that bank market power has its highest growth effect at intermediate values. The latter result is consistent with the literature on relationship lending, which argues that bank competition can have a negative effect on the availability of finance for companies that are informationally more opaque.     

Competition,Financial Intermediation,and Riskiness of Banks: Evidence from the Asia-Pacific Region

From a sample of commercial banks in the Asia-Pacific region over the 1994–2009 period, this study highlights that banks in less competitive markets exhibit lower loan growth and higher instability. Such instability is further followed by a decline in deposit growth, suggesting that Asian banks are also subject to indirect market discipline mechanisms through bank competition. This study therefore sheds light on the importance of enhancing bank competition to overcome bank risk and strengthen financial intermediation. Likewise, this study advocates the importance of strengthening market discipline to reduce bank riskiness regardless of the degree of competition in the banking industry.     

Bank Mergers, Competition, and Liquidity

We model the impact of bank mergers on loan competition, reserve holdings, and aggregate liquidity. A merger changes the distribution of liquidity shocks and creates an internal money market, leading to financial cost efficiencies and more precise estimates of liquidity needs. The merged banks may increase their reserve holdings through an internalization effect or decrease them because of a diversification effect. The merger also affects loan market competition, which in turn modifies the distribution of bank sizes and aggregate liquidity needs. Mergers among large banks tend to increase aggregate liquidity needs and thus the public provision of liquidity through monetary operations of the central bank.     

Time-varying market,interest rate,and exchange rate risk premia in the US commercial bank stock returns

This paper examines the role of market, interest rate, and exchange rate risks in pricing a sample of the US Commercial Bank stocks by developing and estimating a multi-factor model under both unconditional and conditional frameworks. Three different econometric methodologies are used to conduct the estimations and testing. Estimations based on nonlinear seemingly unrelated regression (NLSUR) via GMM approach indicate that interest rate risk is the only priced factor in the unconditional three-factor model. However, based on ‘pricing kernel’ approach by Dumas and Solnik [(1995). J. Finance 50, 445–479], strong evidence of exchange rate risk is found in both large bank and regional bank stocks in the conditional three-factor model with time-varying risk prices. Finally, estimations based on the multivariate GARCH in mean (MGARCH-M) approach where both conditional first and second moments of bank portfolio returns and risk factors are estimated simultaneously show strong evidence of time-varying interest rate and exchange rate risk premia and weak evidence of time-varying world market risk premium for all three bank portfolios, namely those of Money Center bank, Large bank, and Regional bank.     

Structural change and financing constraints

In a multi-industry growth model, firms need external funds for productivity-enhancing R&D, and face financing constraints. The cost of research differs across industries, so financing constraints hinder industry productivity growth unevenly. Equilibrium industry dynamics map into a differences-in-differences regression specification where industry growth depends on the interaction between country financial development and industry R&D intensity. The paper provides a framework for interpreting several empirical results that rely on industry growth data in terms of R&D-induced technology transfer, and identifies a new channel for finance to encourage aggregate growth: the reallocation of resources towards sectors with rapidly expanding technological frontiers.     

Distance to default,subordinated debt,and distress indicators in the banking industry*

The recent financial crisis has highlighted the inadequacy of present supervisory arrangements to identify reliable ex‐ante indicators of banking distress. For a sample of US bank holding companies, we analyse the extent to which distance to default based on market data can be explained using accounting‐based indicators of risk. We show that a larger number of bank fundamentals help predict default for institutions that issue subordinated debt. For banks that issue sub‐debt, we find that higher charter values and low bank capitalizations further increase the power of bank fundamentals to predict default risk.     

INTERNATIONAL BANK FLOWS TO EMERGING MARKETS: INFLUENCE OF SOVEREIGN CREDIT RATINGS AND THEIR REGIONAL SPILLOVER EFFECTS

We examine whether changes in sovereign credit assessments help determine international bank flows to emerging countries. We focus on the bank flows of G7 countries to a sample of 55 emerging market borrowers for 1995–2008. We find evidence indicating that sovereign credit rating revisions have significant and positive influences on international bank flows from developed markets even after controlling for other determinants. In addition, we find strong regional rating spillover effects. Ratings improvements in one emerging market region tend to reduce bank flows to the other regions. However, there is an exception from the Asia Pacific to Eastern Europe.     

From Implicit to Explicit: The Impact of Disclosure Requirements on Hidden Transaction Costs

This paper provides evidence that disclosing corporate bond investors' transaction costs (markups) affects the size of the markups. Until recently, markups were embedded in the reported transaction price and not explicitly disclosed. Without explicit disclosure, investors can estimate their markups using executed transaction prices. However, estimating markups imposes information processing costs on investors, potentially creating information asymmetry between unsophisticated investors and bond‐market professionals. We explore changes in markups after bond‐market professionals were required to explicitly disclose the markup on certain retail trade confirmations. We find that markups decline for trades that are subject to the disclosure requirement relative to those that are not. The findings are pronounced when constraints on investors' information processing capacity limit their ability to be informed about their markups without explicit disclosure.     

Are Banks Affiliated with Bank Holding Companies More Efficient Than Independent Banks? The Recent Experience Regarding Japanese Regional BHCs

Few studies have investigated whether Japanese banks affiliated with bank holding companies are more efficient and profitable than independent banks. The present paper tests this hypothesis by using both a stochastic frontier approach and a market valuation approach. First, our results suggest that banks affiliated with bank holding companies are not more cost-efficient than are independent banks. Because of the brief history of Japanese BHCs, it is fair to conclude that the formation of regional bank holding companies has not achieved efficiency gains so far. Second, we find that banks affiliated with bank holding companies are more profit-efficient than are independent banks. This is particularly apparent when the establishment of the bank holding companies increases market power in regional markets. This supports the Financial Services Agency’s policy to increase the profitability of regional banks through bank consolidation. Finally, based on standard event study methodology, we find that the market did not regard news about the establishment of bank holding companies as significant events.JEL Classification: G21     

The Consumption–Income Ratio,Entrepreneurial Risk,and the U.S. Stock Market

The owners of small noncorporate businesses face substantial and largely uninsurable entrepreneurial risk. They are also an important group of stock owners. This paper explores the role of entrepreneurial risk in explaining time variation in expected U.S. stock returns in the period 1952–2010. It proposes an entrepreneurial distress factor that is based on a cointegrating relationship between aggregate consumption and income from proprietary and nonproprietary wealth. This factor, referred to here as the cpy residual, signals when entrepreneurial income is low in relation to aggregate consumption and other forms of income in the economy. It is highly correlated with cross‐sectional measures of idiosyncratic entrepreneurial and default risk, and it has considerable forecasting power for the expected equity premium. However, the correlation between cpy and the stock market started to decline at the beginning of the 1980s. The decline in this correlation can be associated with increased stock market participation and with the progress of U.S. state‐level bank deregulation. This pattern is consistent with the view that entrepreneurial risk became more easily diversifiable in the wake of U.S. state‐level bank deregulation.
