The Coordination Role of Stress Tests in Bank Risk‐Taking

We examine whether stress tests distort banks' risk‐taking decisions. We study a model in which a regulator may choose to rescue banks in the event of concurrent bank failures. Our analysis reveals a novel coordination role of stress tests. Disclosure of stress‐test results informs banks of the failure likelihood of other banks, which can reduce welfare by facilitating banks' coordination in risk‐taking. However, conducting stress tests also enables the regulator to more effectively intervene banks, coordinating them preemptively into taking lower risks. We find that, if the regulator has a strong incentive to bail out, stress tests improve welfare, whereas if the regulator's incentive to bail out is weak, stress tests impair welfare.     

Monetary Policy,Bank Lending,and the Risk‐Pricing Channel

This paper identifies a monetary policy channel through the risk pricing of bank debt in the market for jumbo certificates of deposit (jumbo CDs). Adverse policy shocks increase debt holder perceptions of bank default, increasing the risk premia for some banks, thereby decreasing their external funding of loans. The results show that contractionary policy increases the sensitivity of jumbo‐CD spreads to leverage and asset risk for small banks, and to leverage for large banks. The results also show a distributional and aggregate effect on banking system jumbo CDs and total loans, producing a risk‐pricing (or market discipline) channel. This channel has implications for monetary and regulatory policies, and financial stability.     

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.     

Competition and Concentration in the New European Banking Landscape

This paper measures the degree of concentration and competition in the enlarged European Union (EU) banking environment over the period 1998–2002. In the empirical part we opt for a methodology as proposed by Panzar and Rosse based on a non‐structural estimation of market competition. Our results suggest that European banks were operating under conditions of monopolistic competition and that bank interest revenues in the 10 new EU member states was earned under conditions of higher competition than those that existed in the old EU banking countries. The opposite result was observed for total operating revenues. Smaller banks earn interest income in a less competitive environment than larger banks, while the opposite is observed for total revenues.     

The Risk‐Taking Channel of Monetary Policy: Exploring All Avenues

The literature on the risk‐taking channel of monetary policy grew quickly, leading to scattered evidence. We examine this channel through different angles, exploring detailed information on loan origination and performance. Ex ante riskier borrowers receive more funding at the extensive margin when interest rates are lower. Ex post performance is independent of the level of interest rates at origination. Still, loans granted in periods of very low and stable interest rates show higher default rates once interest rates start to increase. Risk‐taking is stronger among banks with lower capital ratios, suggesting that this channel may be linked to managerial incentives for risk‐shifting.     

Bank audit practices and loan loss provisioning

I empirically examine the evolution of loan loss accounting across banks that differ categorically by external auditing practice. Using a partial adjustment model, and a sample of 75,505 observations on affiliated banks, 1995–2009, I find evidence of convergence across audit categories in target ratios of provisions for loan losses to nonaccrual loans. This is consistent with a standardized method of accounting for “impaired” loans. I observe less convergence, on the other hand, in target ratios of provisions for loan losses to loans, which appears to accommodate a role for managerial discretion.     

Competition and risk‐taking in investment banking

How does competition affect the investment banking business and the risks individual institutions are exposed to? Using a large sample of investment banks operating in seven developed economies over 1997–2014, we apply a panel VAR model to examine the relationships between competition and risk without assuming any a priori restrictions. Our main finding is that investment banks’ higher risk exposure, measured as a long‐term capital‐at‐risk and return volatility, was facilitated by greater competitive pressures for both boutique investment banks and full‐service investment banks. Overall, we find some evidence that more competition leads to more fragility before and during the recent financial crisis.     

Equity‐Based Incentives,Risk Aversion,and Merger‐Related Risk‐Taking Behavior

We find that post‐merger equity risk is negatively related to the sensitivity of CEO wealth to stock return volatility (vega), but is concentrated in CEOs with high proportions of options and options that are more in‐the‐money. The probability of industrial diversification also increases in vega. Additional tests show that the decline in post‐merger equity risk results in a significant decrease in shareholder wealth. This decrease is concentrated among firms with CEOs having the highest delta and the highest delta and vega. Our results suggest that the increased convexity provided by option‐based compensation does not necessarily increase risk‐taking behavior by CEOs.     

Earnings expectations and the quality of financial services

Using complaint data filed by consumers with the Consumer Financial Protection Bureau against financial institutions, we show that banks receive, on average, 13.3% more customer complaints in the quarter immediately after they narrowly beat analysts’ earnings forecasts. The effect is mainly driven by banks’ attempts to reduce their non-interest expenses to beat earnings benchmarks. The relationship is stronger when bank CEOs receive a greater proportion of incentive-based compensation. Overall, our paper demonstrates how capital market incentives exacerbate shareholder–customer conflicts.     

Bank Mergers and Diversification: Implications for Competition Policy

This paper analyses competition and mergers among risk averse banks. We show that the correlation between the shocks to the demand for loans and the shocks to the supply of deposits induces a strategic interdependence between the two sides of the market. We characterise the role of diversification as a motive for bank mergers and analyse the consequences of mergers on loan and deposit rates. When the value of diversification is sufficiently strong, bank mergers generate an increase in the welfare of borrowers and depositors. If depositors have more correlated shocks than borrowers, bank mergers are relatively worse for depositors than for borrowers.     

Competition and innovation: Evidence from financial services

This paper presents new evidence on the relationship between competition and innovation by extending previous literature from manufacturing to financial services. We introduce a new measure of overall innovation by estimating and enveloping annual minimum cost frontiers to create a global frontier. The distance to the global frontier constitutes each bank’s technology gap, which decreases if the bank manages to innovate. Our innovation measure enables us to derive and estimate the model of Aghion et al. (2005b) at the firm level for the US banking industry. Based on individual bank Call Report data for the period 1984–2004, consistent with theoretical and empirical work by Aghion et al., we find evidence of an inverted-U relationship between competition and innovation that is robust over several different specifications. Further evidence on major structural changes in the US banking industry indicates that banks moved beyond their optimal innovation level and that interstate banking deregulation resulted in lower bank innovation. Policy implications to financial reform and prudential regulation are discussed also.     

Bank Panics,Government Guarantees,and the Long‐Run Size of the Financial Sector: Evidence from Free‐Banking America

Governments attempt to increase the confidence of financial market participants by making implicit or explicit guarantees of uncertain credibility. Confidence in these guarantees presumably alters the size of the financial sector, but observing the long‐run consequences of failed guarantees is difficult. We look to America's free‐banking era and compare the consequences of a broken guarantee during the Indiana‐centered Panic of 1854 to the Panic of 1857 in which guarantees were honored. Our estimates of a model of endogenous market structure indicate substantial negative long‐run consequences to financial depth when panics cast doubt upon a government's ability to honor its guarantees.       

Investment Dynamics and Earnings‐Return Properties: A Structural Approach

We propose the standard neoclassical model of investment under uncertainty with short‐run adjustment frictions as a benchmark for earnings‐return patterns absent accounting influences. We show that our proposed benchmark generates a wide range of earnings‐return patterns documented in accounting research. Notably, our model generates a concave earnings‐return relation, similar to that of Basu [1997], and predicts that the earnings‐return concavity increases with the volatility of firms’ underlying shock processes and decreases with the level of firms’ investments. We find strong empirical support for these predictions. Overall, our evidence suggests that our proposed benchmark is useful for understanding the joint dynamics of variables of interest to accounting research (e.g., earnings, returns, investment, market‐to‐book) absent accounting influences, a necessary precondition for inferring the effects of accounting from these dynamics.     

Capital Regulation and Competition as a Moderator for Banking Stability

Capital regulation forces banks to fund a substantial amount of their investments with equity. This creates a buffer against losses but also increases the cost of funding. If higher funding costs translate into higher loan interest rates, the bank's assets are also likely to become more risky, which may destabilize the lending bank. This paper argues that the level of competition in the banking sector can determine whether the buffer or cost effect prevails. The endogenous level of competition may be crucial in determining the efficiency of capital regulation in undercapitalized banking sectors, with excess capacities and correlated risks.     

The role of bank monitoring in corporate governance: Evidence from borrowers’ earnings management behavior

In this paper, we examine the corporate governance role of banks by investigating the effect of bank monitoring on the borrowers’ earnings management behavior. Our analyses suggest that a borrowing firm’s earnings management behavior generally decreases as the strength of bank monitoring increases. The strength of bank monitoring is measured as (1) the magnitude of a bank loan, (2) the reputation (rank) of a lead bank, (3) the length of a bank loan, and (4) the number of lenders. These results imply that bank monitoring plays an important role in the corporate governance of bank-dependent firms. We further examine other bank loan characteristics (collateral, refinancing, loan types, and loan purposes) and their effects on borrowers’ earnings management behavior. Our analyses show that collateral and loan types are significantly associated with borrowers’ earnings management behavior while refinancing and loan purposes have no association.     

Competition in fragmented markets: New evidence from the German banking industry in the light of the subprime crisis

Of all of the EU member states, Germany has the largest banking market. However, not all German banking institutions necessarily face fierce competition. Because the industry is highly fragmented, strict separation of the three existing banking pillars may impede competition, with negative effects on financial stability. We assess the competitive stances of 1,888 universal banks from 2001 to 2009 by using the Panzar–Rosse revenue test. We find evidence that measuring competition at an average country level does not necessarily generate valid evaluations of fragmented markets. In addition, we find no clear indication that either the particular objectives of cooperative and savings banks or the legal protection of these institutions impedes competition or discriminates against private banks. Therefore, as long as the relationship between competition and financial stability is dubious, the overall effect and the social costs or benefits of political measures that influence the structure of the German banking market are at least questionable.     

Delayed Expected Loss Recognition and the Risk Profile of Banks

This paper investigates the extent to which delayed expected loan loss recognition (DELR) is associated with greater vulnerability of banks to three distinct dimensions of risk: (1) stock market liquidity risk, (2) downside tail risk of individual banks, and (3) codependence of downside tail risk among banks. We hypothesize that DELR increases vulnerability to downside risk by creating expected loss overhangs that threaten future capital adequacy and by degrading bank transparency, which increases financing frictions and opportunities for risk‐shifting. We find that DELR is associated with higher correlations between bank‐level illiquidity and both aggregate banking sector illiquidity and market returns (i.e., higher liquidity risks) during recessions, suggesting that high DELR banks as a group may simultaneously face elevated financing frictions and enhanced opportunities for risk‐shifting behavior in crisis periods. With respect to downside risk, we find that during recessions DELR is associated with significantly higher risk of individual banks suffering severe drops in their equity values, where this association is magnified for banks with low capital levels. Consistent with increased systemic risk, we find that DELR is associated with significantly higher codependence between downside risk of individual banks and downside risk of the banking sector. We theorize that downside risk vulnerability at the individual bank level can translate into systemic risk by virtue of DELR creating a common source of risk vulnerability across high DELR banks simultaneously, which leads to risk codependence among banks and systemic effects from banks acting as part of a herd.     

Inside the black box: Bank credit allocation in China’s private sector

This study examines how the Chinese state-owned banks allocate loans to private firms. We find that the banks extend loans to financially healthier and better-governed firms, which implies that the banks use commercial judgments in this segment of the market. We also find that having the state as a minority owner helps firms obtain bank loans and this suggests that political connections play a role in gaining access to bank finance. In addition, we find that commercial judgments are important determinants of the lending decisions for manufacturing firms, large firms, and firms located in regions with a more developed banking sector; political connections are important for firms in service industries, large firms, and firms located in areas with a less developed banking sector.     

How bank capital buffers vary across countries: The influence of cost of deposits,market power and bank regulation

This paper analyzes the bank and country determinants of capital buffers using a panel data of 1337 banks in 70 countries between 1992 and 2002. After controlling for adjustment costs and the endogeneity of explanatory variables, the results show that capital buffers are positively related to the cost of deposits and bank market power, although the relations vary across countries depending on regulation, supervision, and institutions. Their impact is the result of two generally opposing effects: restrictions on bank activities and official supervision reduce the incentives to hold capital buffers by weakening market discipline, but at the same time they promote higher capital buffers by increasing market power. Institutional quality has the two opposite effects. Better accounting disclosure and less generous deposit insurance, however, have a clear positive effect on capital buffers by both strengthening market discipline and making charter value better able to reduce risk-taking incentives.     

Banking Competition,Collateral Constraints,and Optimal Monetary Policy

We analyze optimal monetary policy in a model with two distinct financial frictions: monopolistically competitive banks that charge endogenous lending spreads, and collateral constraints. We show that welfare maximization is equivalent to stabilization of four goals: inflation, output gap, the “consumption gap” between borrowers and savers, and a “housing gap” that measures the distortion in the distribution of the collateralizable asset between both groups. Collateral constraints create a trade‐off between stabilization goals. Following both productivity and financial shocks, and relative to strict inflation targeting, the optimal policy implies sharper movements in the policy rate, aimed primarily at reducing fluctuations in asset prices and hence in borrowers' net worth. The policy trade‐offs become amplified as banking competition increases, due to the fall in lending spreads and the resulting increase in borrowers' leverage.
