Information effect of entry into credit ratings market: The case of insurers' ratings

The paper analyzes the effect of competition between credit rating agencies (CRAs) on the information content of ratings. We show that a monopolistic CRA pools sellers into multiple rating classes and has partial market coverage. This provides an opportunity for market entry. The entrant designs a rating scale distinct from that of the incumbent. It targets higher-than-average companies in each rating grade of the incumbent's rating scale and employs more stringent rating standards. We use Standard and Poor's (S&P) entry into the market for insurance ratings previously covered by a monopolist, A.M. Best, to empirically test the impact of entry on the information content of ratings. The empirical analysis reveals that S&P required higher standards to assign a rating similar to the one assigned by A.M. Best and that higher-than-average quality insurers in each rating category of A.M. Best chose to receive a second rating from S&P.     

Regulations, Supervision Approaches and Acquisition Likelihood in the Asian Banking Industry

We investigate the association between the regulatory and supervision framework and the likelihood of being involved in acquisitions either as acquirer or target in the Asian banking industry over the period 1998–2004. The sample consists of 473 commercial banks operating in 9 markets, a total of 2,693 yearly observations. We use information from the new database of the World Bank and examine various regulations such as the level of accounting and information disclosure requirements, the restrictions on bank activities, the degree of official disciplinary power, and capital adequacy requirements. Our results suggest that the latter two influenced the probability of becoming a target or acquirer; however, restriction on activities and disclosure requirements had no impact on the acquisition likelihood.     

Credit agency regulation and the impact of credit ratings in the international bond market

The use of credit ratings in financial and other legal documents — both in the USA and Europe —, has led to a situation in which the major rating agencies have become (largely unwilling) participants in the legislative process. This situation has become partly formalized in the US (and is being repeated elsewhere in the European Union, Eastern Europe and Latin America) through the creation of officially ‘recognized’ agencies whose ratings now carry the imprimatur of the Securities and Exchange Commission. The purpose of this paper is to contribute to the debate on the necessity for formal legal status to be sustained in the market for bond credit ratings. In this context, the criteria for a credible rating agency are examined and evidence is provided on one element of the criteria which is under-researched: namely, the impact of the ratings in the market place. The influence of rating agencies in international capital markets is assessed through an analysis of the impact of ratings on the yields of bonds, represented by a comprehensive sample of actively traded debt. The sample contains analysis of ratings introductions on both new and seasoned debt and also examines the impact of ratings revisions. It is concluded that official recognition has no market-based role and it is argued that ratings are used by regulators because of the success of the major agencies in performing their market function.     

The price of liquidity: The effects of market conditions and bank characteristics

We study the prices that individual banks pay for liquidity (captured by borrowing rates in repos with the central bank and benchmarked by the overnight index swap) as a function of market conditions and bank characteristics. These prices depend in particular on the distribution of liquidity across banks, which is calculated over time using individual bank-level data on reserve requirements and actual holdings. Banks pay more for liquidity when positions are more imbalanced across banks, consistent with the existence of short squeezing. We also show that small banks pay more for liquidity and are more vulnerable to squeezes. Healthier banks pay less but, contrary to what one might expect, banks in formal liquidity networks do not. State guarantees reduce the price of liquidity but do not protect against squeezes.     

Cross-border banking,bank market structures and market power: Theory and cross-country evidence

Patterns in cross-border banking have changed since the global financial crisis. This may affect domestic bank market structures and macroeconomic stability in the longer term. In this study, I theoretically and empirically analyze how different modes of cross-border banking impact bank concentration and market power. I use a two-country general equilibrium model with heterogeneous banks developed by DeBlas and Russ (2010a) to grasp the effect of cross-border lending and foreign direct investment in the banking sector on bank market structures. The model suggests that both cross-border lending and bank FDI mitigate concentration. Empirical evidence from a panel dataset of 18 OECD countries supports the theoretical predictions: higher volumes of bank FDI and of cross-border lending coincide with lower Herfindahl-indexes in bank credit markets.     

The impact of gender diversity on shareholder wealth: Evidence from European bank M&A

We explore the association between board gender diversity and shareholder value creation. Specifically, we investigate the impact of gender diversity on the economic impact of bank mergers and acquisitions (M&A). We employ a multi-year sample of M&A announced by European listed banks and find that: (i) the presence of women on the board of directors has a positive and statistically significant effect on acquirer gains; and (ii) boards with three or more women, or where women represent more than 25% of the board, have a stronger impact on acquirer gains than in the opposite case, consistent with critical mass theory. Moreover, banks with a critical mass of female directors perform better in undertaking value-enhancing M&A after the global financial crisis. Policy makers and practitioners could benefit from the findings by exploiting the advantages of board heterogeneity in terms of gender.     

Natural disasters and economic growth: The role of banking market structure

Following a natural disaster, the rate of economic growth recovers faster in less competitive banking markets. A 10% reduction in competition increases the rate of economic growth by 0.3%. In less competitive markets, banks respond to a disaster by increasing the supply of real estate credit by refinancing mortgage loans, but do not lend more to businesses or consumers. Instead, government agencies provide disaster loans to affected businesses and households. Smaller, profitable and well-capitalized institutions that rely more on traditional retail banking originate most mortgage credit.     

The impact of off-balance-sheet regulations on bank risk-taking: Evidence from China

The release of new asset management rules has played a positive role in regulating the asset management business of financial institutions, preventing and controlling financial risk. It has also had an important impact on the management of banks’ off-balance-sheet (OBS) innovation. This paper uses unbalanced panel data on 75 commercial banks in China from 2007 to 2017 and combines a theoretical and an empirical model to study the development of bank OBS innovation and bank risk taking from the perspective of new asset management regulations. The analysis finds (1) the rapid development of OBS innovation will increase bank risk taking and (2) the solution to the problem of rigid payment is conducive to reducing the risk taken by Chinese commercial banks when providing OBS innovation.     

Dividend payout strategies and bank survival likelihood: A cross-country analysis

In this cross-country study, we examine whether dividend payout decisions affect the survival likelihood of banks. Using unique international banking data from 11 countries from 2010 to 2019, we find that higher levels of cash dividend payouts increase a bank's survival likelihood, as paying dividends lowers agency problems and cost of debt and facilitates greater public monitoring. Our extended analysis shows an inverted U-shaped relation between large dividends and survival likelihood. At higher levels, payout is related to a safer position of banks in terms of default; however, at very high levels of dividends, when the levels of payouts exceed a threshold, such payout lowers the likelihood of survival. We additionally investigate the effect of the bank type to assess whether differential effects could be realised under the constrained dividend model of Islamic banks compared to the conventional banking model. Our results, interestingly, show that the positive effect of dividend payouts on bank survival is more pronounced in conventional than Islamic banks. This finding is explained by the dominant liquidity management challenges pertaining to the Islamic banking business model in which banks retain more cash and pay lower dividends. Our findings offer important insights and policy implications for regulators, bankers and a broad set of stakeholders engaging with both banking sectors.     

The impact of sovereign rating actions on bank ratings in emerging markets

This paper analyses the effects of sovereign rating actions on the credit ratings of banks in emerging markets, using a sample from three global rating agencies across 54 countries for 1999–2009. Despite widespread attention to sovereign ratings and bank ratings, no previous study has investigated the link in this manner. We find that sovereign rating upgrades (downgrades) have strong effects on bank rating upgrades (downgrades). The impact of sovereign watch status on bank rating actions is much weaker and often insignificant. The sensitivity of banks’ ratings to sovereign rating actions is affected by the countries’ economic and financial freedom and by macroeconomic conditions. Ratings of banks with different ownership structures are all influenced strongly by the sovereign rating, with some variation depending on the countries’ characteristics. Emerging market bank ratings are less likely to follow sovereign rating downgrades during the recent financial crisis period.     

Which banks are more risky? The impact of business models on bank stability

In this paper, we analyze the impact of business models on bank stability in 15 EU countries between 2002 and 2011. We represent banks’ business models by the share of non-interest income in total operating income and the share of non-deposit funding in total liabilities. In contrast to the literature, we include in our sample a large number of unlisted banks, which represent the majority of banks in the EU. We believe this to be important, since many unlisted banks typically have a more retail-oriented business model. We show that banks will be significantly more stable and profitable if they increase their share of non-interest income, indicating that substantial benefits are to be gained from income diversification. Such benefits are particularly large for savings and cooperative banks. Investment banks, in contrast, become significantly more risky. Diversifying into non-deposit funding has a different impact as well. While retail-oriented banks will be significantly less stable if they increase their share of non-deposit funding, investment banks will be significantly more stable. These findings indicate that it is important to enlarge the sample of banks and to include different types of banks with different business models in order to arrive at general conclusions about the effect of non-interest income and non-deposit funding on bank stability.     

Impact of central bank independence and transparency on international equity portfolio allocation: A cross-country analysis

In this study, we analyse the effects of central bank independence (CBI) and central bank transparency (CBT) and their interactions with institutional quality on foreign equity portfolio inflows. Employing a dataset from 42 countries over the period from 2001 to 2014, we find strong evidence that independent and transparent central bank has a positive and significant influence on foreign equity investment inflows. Further analysis shows that institutional quality interacts with central bank independence and transparency in attracting foreign equity portfolio. Our results are robust to alternative specifications, endogeneity concerns and that economic policy uncertainty increases asymmetric information and deters foreign equity portfolio investment inflows.     

Stress tests and asset quality reviews of banks: A policy announcement tool

It is common in the supervision of banks to perform and disclose a simultaneous standardized assessment of their asset quality, organizational effectiveness, strategic viability and resilience to financial turmoil. By investigating the European Central Bank 2014 Comprehensive Assessment and the stock reactions of the banks to its findings, we find that this process provides limited assistance to the market in sorting good from troubled banks. Notwithstanding, the market adjusts to these findings, since it understands that they signal the stance of supervisory policy toward banking activities, which begets the level of regulatory risk and cost for the supervised banks.     

A quantitative analysis of qualitative arguments in a bank merger

This study analyzes a merger between two Scandinavian universal banks to determine the arguments for the merger at the time of the merger announcement. The merger was a response to changes in legislative and competitive environment, as well as a quest for broader functional competency and improved competitive position by integrating a smaller, more successful bank into a state-owned bank. Overall, the cognitive maps used in the analysis reveal that the most important causes of the merger were complementing branch networks and competencies, particularly in corporate banking. The most important predicted effects were improvements in the profitability and market position.     

Audit market concentration,audit fees,and audit quality: A cross-country analysis of complex audit clients

Regulators around the world are concerned about the potentially harmful effects of high audit market concentration on audit pricing and quality. However, results in the overall literature have failed to reach consensus on this issue. We contribute to this debate by arguing that the audit market is segmented and that concentration in the Big 4 segment of the market leads to higher audit pricing. Accordingly, our analyses use international data and focus on concentration within the Big 4 group of firms across countries. We find that audit fees are increasing in our concentration measure for clients where the barriers to entry by competing auditors are higher, as proxied by client size, international operations, and IFRS use. Finally, we find evidence that audit quality is decreasing in Big 4 market concentration for these types of engagements. This indicates a wealth transfer from shareholders to audit firms when auditor concentration is high because these complex clients are charged more, but receive audits that are of lower quality.

Problem bank loans, conflicts of interest, and institutions

I consider problem bank loans as the outcome of decisions made by banks in the dual role they serve as financial intermediaries. This dual role necessarily introduces conflicts of interest that can lead to bank mismanagement and consequently problem bank loans. Because bank activities take place within the tangible and intangible structure of institutions, institutions may affect the quality of bank loans. I consider legal, political, sociological, economic, and banking institutions and explore their contribution to problem bank loans. I find support that a variety of institutions impact the share of bank assets that are non-performing.     

The institutional memory hypothesis and the procyclicality of bank lending behavior

We test a new hypothesis that may help explain the procyclicality of bank lending. The institutional memory hypothesis is driven by deterioration in the ability of loan officers over the bank's lending cycle that results in an easing of credit standards. We test this hypothesis using data from individual US banks over 1980–2000: over 200,000 bank-level observations on commercial loan growth, over 2,000,000 loan-level observations on interest rate premiums, and over 2000 bank-level observations on credit standards and loan spreads from bank management survey responses. The empirical analysis supports the hypothesis, although there are differences by bank size class.     

Self-fulfilling dynamics: The interactions of sovereign spreads,sovereign ratings and bank ratings during the euro financial crisis

During the euro-area financial crisis, interactions among sovereign spreads, sovereign credit ratings, and bank credit ratings appeared to have been characterized by self-generating feedback loops. To investigate the existence of feedback loops, we consider a panel of five euro-area stressed countries within a three-equation simultaneous system in which sovereign spreads, sovereign ratings and bank ratings are endogenous. We estimate the system using two approaches. First we apply GMM estimation, which allows us to calculate persistence and multiplier effects. Second, we apply a new, system time-varying-parameter technique that provides bias-free estimates. Our results show that sovereign ratings, sovereign spreads, and bank ratings strongly interacted with each other during the euro crisis, confirming strong doom-loop effects.
