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.     

The Relation Between Bank Resolutions and Information Environment: Evidence from the Auctions for Failed Banks

This study examines the impact of disclosure requirements on the resolution costs of failed banks. Consistent with the hypothesis that disclosure requirements mitigate information asymmetries in the auctions for failed banks, I find that, when failed banks are subject to more comprehensive disclosure requirements, regulators incur lower costs of closing a bank and retain a lower portion of the failed bank's assets, while bidders that are geographically more distant are more likely to participate in the bidding for the failed bank. The paper provides new insights into the relation between disclosure and the reorganization of a banking system when the regulators' preferred plan of action is to promote the acquisition of undercapitalized banks by healthy ones. The results suggest that disclosure regulation policy influences the cost of resolution of a bank and, as a result, could be an important factor in the definition of the optimal resolution strategy during a banking crisis event.     

Theories of bank behavior under capital regulation

This paper reviews academic studies of bank capital regulation in an effort to evaluate the intellectual foundation for the imposition of the Basel I and Basel II systems of risk-based capital requirements. The theoretical literature yields general agreement about the immediate effects of capital requirements on bank lending and loan rates and the longer-term impacts on bank ratios of equity to total or risk-adjusted assets. This literature produces highly mixed predictions, however, regarding the effects of capital regulation on asset risk and overall safety and soundness for the banking system as a whole. Thus, the intellectual foundation for the present capital-regulation regime is not particularly strong. The mixed conclusions in the academic literature on banking certainly do not provide unqualified support for moving to an even more stringent and costly system of capital requirements. These widely ambiguous results do suggest, however, that assessing the implications of capital regulation for balance-sheet risk and monitoring effort in diverse banking systems is an important agenda for future theoretical research in the banking area.     

Bank capital buffers in a dynamic model

We estimate a dynamic structural banking model to examine the interaction between risk-weighted capital adequacy and unweighted leverage requirements, their differential impact on bank lending, and equity buffer accumulation in excess of regulatory minima. Tighter risk-weighted capital requirements reduce loan supplies and lead to an endogenous fall in bank profitability, reducing bank incentives to accumulate equity buffers and, therefore, increasing the incidence of bank failure. Alternatively, tighter leverage requirements increase lending, preserve bank charter value, and incentives to accumulate equity buffers leading to lower bank failure rates.     

Capital regulation,heterogeneous monitoring costs,and aggregate loan quality

This paper develops a banking-sector framework with heterogeneous loan monitoring costs. Banks are exposed to the moral hazard behavior of borrowers and endogenously choose whether to monitor their loans to eliminate this exposure. After analyzing an unregulated banking system, we examine several cases in which regulatory capital requirements bind the notional loan supplies of various subsets of banks. To gauge the impact of capital requirements, we define loan ‘quality’ in terms of either the ratio of monitored to total loans or the ratio of monitoring banks to total bank population. Under the assumption of a specific cross-sectional distribution of banks, our simulations show that the imposition of binding capital requirements on a previously unregulated banking system unambiguously increases the market loan rate and reduces aggregate lending, but has an ambiguous effect on loan ‘quality’. Nevertheless, once capital requirements are in place, the simulations indicate that regulators can contribute to higher overall loan ‘quality’ by toughening capital requirements.     

Does banking system transparency enhance bank competition? Cross-country evidence

There seems to be a consensus among regulators and scholars that in order to improve the functioning of a banking system it is necessary to raise the level of bank information disclosure. However, its influence on bank competition – which is an important factor affecting the efficiency and stability of the banking system – is left out of consideration. To test whether greater bank information disclosure is associated with both lower market power and lower concentration in the banking markets, we use country-level data covering the years 1998, 2001, 2005 and 2010. Our findings show that countries with higher levels of bank transparency have lower levels of bank concentration, while the link between transparency and market power is less pronounced. We also show that the reduction of competition due to stricter disclosure requirements depends on bank credit risks and the relationship is U-shaped.     

Time‐Varying Capital Requirements and Disclosure Rules: Effects on Capitalization and Lending Decisions

We investigate how banks’ capital and lending decisions respond to changes in bank‐specific capital and disclosure requirements. We find that an increase in the bank‐specific regulatory capital requirement results in a higher bank capital ratio, brought about via less asset risk. A decrease in the requirement implies more lending to firms but also less Tier 1 capital and higher bank leverage. We do not observe differences between confidential and public disclosure of capital requirements. Our results empirically illustrate a tradeoff between bank resilience and a fostering of the economy through more bank lending using banks’ capital requirement as policy instrument.     

Bank governance,regulation, supervision,and risk reporting: Evidence from operational risk disclosures in European banks

This paper investigates the direct and joint effects of bank governance, regulation, and supervision on the quality of risk reporting in the banking industry, as proxied for by operational risk disclosure (ORD) quality in European banks. After controlling for the endogeneity between bank stability and risk reporting quality, we find that banks having a higher proportion of outside board directors, lower executive ownership, concentrated outside non-governmental ownership, and more active audit committee, and operating under regulations promoting bank competition (i.e., less stringent entry to banking requirements) provide ORD of higher quality. In addition, we find that the contribution of bank supervisors to the enhancement of ORD quality depends on the ownership structure of the bank. Specifically, powerful and independent bank supervisors mitigate the incentives for entrenched bank executives to withhold voluntary ORD. Moreover, bank supervisors and largest shareholders perform substitutive roles in monitoring the bank management's compliance with mandatory ORD requirements. For the sake of enhancing risk reporting quality in banks, our findings recommend sustaining board independence, enhancing audit committee activity, easing entry to banking requirements, and promoting a more proactive role for bank supervisors.     

银行监管和股东属性对银行风险的影响——基于新兴经济体的监管数据分析

银行监管按世界银行的标准划分为总体监管和12类分项监管;银行大股东属性包括政府类、金融企业类、外资类等.总体监管可以有效地降低银行风险;大股东为工业类、金融类企业的银行能够更好地控制风险,而家族类银行的风险程度较高;通过对分项监管进行研究可以发现,加强对所有权、资本要求、经营活动限制、外部审计要求、流动性、存款保险制度、退出及监管效率八个方面的监管可降低银行总体风险,而加强准入、内部管理、资产分类配置、信息披露这四类监管反而会增加银行总体风险.     

Regulating securities analysts

We examine the effects of regulations designed to address the potential conflict of interest that arises when sell-side analyst research is not independent of investment banking. We focus on two types of regulation: (1) internal barriers between equity research and investment banking that restrict communication; and (2) disclosure requirements relating to analyst compensation. We find that information barriers can increase research effort and improve report quality by limiting an investment bank's ability to distort its analyst's incentives. However, this type of regulation can also reduce information production and lower the quality of reports if an investment bank benefits directly from research activity. Disclosure requirements, on the other hand, unambiguously lead to more informative prices and a higher report quality relative to either information barriers or no regulation.     

资本监管、风险承担与货币政策传导机制——研究综述与展望

频频爆发的银行危机暴露了以资本监管为核心的巴塞尔协议的内在缺陷,学术界就资本监管的微观效应和宏观效应展开了激烈的讨论.从文献研究的角度,通过回顾和分析理论界关于资本监管、银行风险承担和货币政策传导机制三者之间复杂关系的研究,可以看出,在微观意义上,关于资本监管对银行风险承担行为影响的研究忽视了对资本监管框架效应的分析;在宏观意义上,资本监管的强化给货币政策传导机制带来了新的渠道,即银行资本渠道和风险承担渠道.这两种新的传导机制在后金融危机时代,是研究宏观审慎监管框架下货币政策效应的核心命题.     

How accounting and auditing systems can counteract risk-shifting of safety-nets in banking: Some international evidence

This paper suggests that accounting and auditing systems can be effective devices to counteract tendencies for firm risk-taking associated with bank safety nets. Results are obtained from an international sample of publicly traded banks after controlling for other regulatory control devices for bank risk such as restrictions on banking activities, minimum regulatory capital requirements and official discipline. The efficacy of accounting and auditing systems in controlling bank risk diminishes with bank charter value and increases with moral hazard stemming from a country's deposit insurance. The results also indicate that accounting and auditing systems are complements for minimum capital requirements, but substitutes for restrictions on bank activities and official discipline.

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/sovereign risk spillovers in the European debt crisis

This paper investigates contagion between bank and sovereign default risk in Europe over the period 2007–2012. We define contagion as excess correlation, i.e. correlation between banks and sovereigns over and above what is explained by common factors, using CDS spreads at the bank and at the sovereign level. Moreover, we investigate the determinants of contagion by analyzing bank-specific as well as country-specific variables and their interaction. Using the EBA’s disclosure of sovereign exposures of banks, we provide empirical evidence that three contagion channels are at work: a guarantee channel, an asset holdings channel and a collateral channel. We find that banks with a weak capital buffer, a weak funding structure and less traditional banking activities are particularly vulnerable to risk spillovers. At the country level, the debt ratio is the most important driver of contagion. Furthermore, the impact of government interventions on contagion depends on the type of intervention, with outright capital injections being the most effective measure in reducing spillover intensity.     

Banking regulation and the output cost of banking crises

Using a cross-section time-series of 47 banking crisis episodes in 35 industrial and emerging market economies between the 1970s and 2003, this study analyses the relationship between banking regulation and supervision, and the severity of banking crises measured in terms of the magnitude of output loss. The empirical results show that countries that provide comprehensive deposit insurance coverage and enforce strict bank capital adequacy requirements experience a smaller output cost of crises. Restrictions on bank activities also influence the severity of crises. The results, however, do not suggest that there is a significant impact of bank supervision. In addition, there is no robust evidence that the magnitude of the output cost of crises depends on the extent of banks’ financial intermediation.     

Loan pricing under Basel II in an imperfectly competitive banking market

The new Basel II Accord (2006), established new and revised capital requirements for banks. In this paper we analyze and estimate the possible effects of the new rules on the pricing of bank loans. We relate to the two approaches for capital requirements (internal and standardized) and distinguish between retail and corporate customers. Our loan-equation is based on a model of a banking firm facing uncertainty operating in an imperfectly competitive loan market. We use Israeli economic data and data of a leading Israeli bank. The main results indicate that high quality corporate and retail customers will enjoy a reduction in loan interest rates in (big) banks which, most probably, will adopt the IRB approach. On the other hand high risk customers will benefit by shifting to (small) banks that adopt the standardized approach.     

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.     

资本市场开放能否提高企业信息披露质量？——基于“沪港通”和年报文本挖掘的分析

提高信息披露质量对于改善上市公司治理结构和保护股东权益具有重要意义。本文利用2014年开通的“沪港通”机制这一准自然实验,研究资本市场开放是否提高了企业的信息披露质量。从2010-2019年A股上市公司年报文本中提炼可读性指标衡量信息披露质量,使用匹配和双重差分方法进行实证研究,发现“沪港通”机制实施以后,标的公司(纳入“沪港通”的A股上市公司)的信息披露质量显著提高。这一结论对不同的估计方法、样本区间及控制变量组均保持稳健。异质性分析表明,对于盈余操纵水平较高、股价信息含量较低的企业,资本市场开放能够更好地改善其信息披露质量。本文丰富了资本市场开放对企业行为和绩效影响的实证研究,为继续推进资本市场开放政策提供了理论依据。     

Bank Portfolio Allocation: The Impact of Capital Requirements, Regulatory Monitoring, and Economic Conditions

This paper develops a structural, dynamic model of a banking firm to analyze how banks adjust their loan portfolios over time. In the model, banks experience capital shocks, face uncertain future loan demand, and incur costs based on their proximity to regulatory minimum capital requirements and the intensity of regulatory monitoring. Implications of the model then are estimated using panel data on large U.S. commercial banks operating continuously between December 1989 and December 1997. The estimated model is used to simulate the optimal bank response to (1) past and proposed changes in capital requirements, (2) changes in regulatory monitoring intensity, and (3) economic downturns. The simulation results are used to shed light on the decline in loan growth and the rise in bank capital ratios witnessed over a decade ago as well as the possible impact of the current proposed modification to capital requirements.
