REGULATORY FORBEARANCE AND DEPOSITOR MARKET DISCIPLINE: EVIDENCE FROM SAVINGS BANKS IN KOREA

This paper investigates whether regulatory forbearance for savings banks in Korea affects the market discipline of depositors using data from 2000 to 2010, which are characterized by a series of exits of savings banks. We find that depositors' sensitivity to the savings banks' asset quality decreases when there is regulatory forbearance for failing savings banks. This forbearance effect is also observed in the behavior of the depositors of the neighboring savings banks in the same business area. These results suggest that regulatory forbearance may cause depositors to misjudge bank risks, increasing the expected costs of bank failure. (JEL G21, G28)     

Delay determinants of European Banking Union implementation

Most countries in the European Union (EU) delay the transposition of European Commission (EC) directives, which aim at reforming banking supervision, resolution, and deposit insurance. We compile a systematic overview of these delays to investigate if they result from strategic considerations of governments conditional on the state of their financial, regulatory, and political systems. Transposition delays pertaining to the three Banking Union directives differ considerably across the 28 EU members. Bivariate regression analyses suggest that existing national bank regulation and supervision drive delays the most. Political factors are less relevant. These results are qualitatively insensitive to alternative estimation methods and lag structures. Multivariate analyses highlight that well-stocked deposit insurance schemes speed-up the implementation of capital requirements, banking systems with many banks are slower in implementing new bank rescue and resolution rules, and countries with a more intensive sovereign-bank nexus delay the harmonization of EU deposit insurance more.     

BANK CAPITAL FORBEARANCE AND PUBLIC POLICY

Recently, the bank regulatory agencies have adopted capital forbearance programs to permit some troubled agriculture and energy banks to operate temporarily with capital levels below the regulatory minimum requirement. In a world with federal deposit insurance and a lender of last resort, bank capital is no longer viewed by all depositors as the primary protector of their funds. Thus, they reduce their market discipline. Bank owners/ managers are likely to respond by increasing their risk exposure in an attempt to regain profitability. If they win, they keep all the gains; if they lose, the losses are passed on to the Federal Deposit Insurance Corporation (FDIC). A preferred policy is to require these banks to raise additional capital at this time or to be sold. Capital forbearance is forbearance of incumbent bank management/owners, not of bank customers.     

A model of takeovers of foreign banks

This paper investigates the determinants of the takeover of a foreign bank by a domestic bank whereby the former becomes a branch of the latter. Each bank is initially supervised by a national agency that cares about closure costs and deposit insurance payouts, and may decide the early closure of the bank on the basis of supervisory information. Under the principle of home country control, the takeover moves responsibility for both the supervision of the foreign bank and the insurance of the foreign deposits to the domestic agency. It is shown that the takeover is more likely to happen if the foreign bank is small (relative to the foreign banking market) and its investments are risky (relative to those of the domestic bank). Moreover, the takeover is in general welfare improving for both countries.

AN OPTIMAL SCHEME FOR INJECTING PUBLIC FUNDS UNDER THE MORAL HAZARD INCENTIVE FOR BANKS

I consider whether the injection of cash funds into a bank through the purchase of securities together with a bank closure policy can be designed as a strong incentive instrument for preventing the bank from taking moral hazard action in the presence of deposit insurance. Under certain conditions, the regulator's optimal policy can be to inject new cash funds into a bank through the purchase of securities, even though there are no bankruptcy costs. Furthermore, the regulator may transform the private bank into a government-owned bank. However, this kind of injection policy cannot be independent of the bank closure policy.     

Activity strategies,information asymmetry,and bank opacity

Using a large panel of US bank holding companies from 2001 to 2015, we investigate the association between functional diversification and bank earnings management. We document a positive relationship between bank earnings management and bank diversification. Our findings are consistent with the hypothesis that diversification increases the asymmetric information of banks, leading to greater discretionary power by bank managers. This effect is most prevalent in smaller banks and non-dividend paying banks. The impact of diversification on earnings management is less pronounced during the crisis. Our study is of interest to regulators and other stakeholders who examine factors which affect behavior of bank managers.     

Banking Competition,Risk and Regulation*

In a dynamic framework, commercial banks compete for customers by setting acceptance criteria for granting loans, while taking into account regulatory requirements. By easing its acceptance criteria a bank faces a trade‐off between attracting more demand for loans, thus making higher per‐period profits, and deterioration in the quality of its loan portfolio, thus tolerating a higher risk of failure. Our main results state that more stringent capital adequacy requirements lead banks to set stricter acceptance criteria, and that increased competition in the banking industry leads to riskier bank behaviour. It is shown that risk‐adjusted regulation is effective. In an extension of our basic model, we show that it may be beneficial for a bank to hold more equity than prescribed by the regulator, even though issuing equity is more expensive than attracting deposits.     

How have banks fared following a borrower's financial distress?

This paper is the first to study the impact of a borrower's reorganization filing on its lead lending bank and second lending bank. This study analyzes 96 reorganization filings in Taiwan during the period 1995–2006. It is substantiated that the market's reaction to these filings is not indiscriminate and that the forbearance lending to a reorganization filing borrower suggests the lead bank's little concern for its shareholder wealth.     

The relationship banking paradox: No pain no gain versus raison d'être

Relationship banking paradox refers to the case that credit market competition may threaten relationship banking practice, but it may stimulate it as well because of differentiation. Using a mixed model of adverse selection and double moral hazard, this paper shows that for some parameter values, relationship banking arises even when the banks compete à la Bertrand, hence supporting the no pain no gain hypothesis. This is due to multilayer nature of the information asymmetry by double moral hazard where an outside bank that does not have the borrower's proprietary information is unable to exert optimal levels of effort in the continuation game.     

BANKING UNION IN EUROPE: HOW MUCH CENTRALISATION IS NEEDED?

We examine the efficiency of banking regulation in a federation with two tiers of government and highly integrated banking systems. We assume that policy makers have incomplete information about banks’ true health, and banking sector turmoil can generate cross‐border spill‐over effects. We show that, in such an environment, the decentralisation of policy responsibilities for the regulation of banks can achieve the first‐best allocation and ensure financial stability. While national governments design banking regulations, the federal policy maker authorises inter‐regional income redistribution payments throughout the federation. Our results suggest that strengthening national responsibilities in banking regulation and supervision in the course of the further development of the European banking union may be advisable.     

Modes of foreign bank entry and effects on lending rates: Theory and evidence

Policy makers who decide to liberalize foreign bank entry frequently put limitations on the mode of entry. We study how different entry modes affect the lending rates of foreign and domestic banks. In our model, the mode of entry determines whether a foreign bank inherits a customer base. This, in turn, affects how information is distributed between foreign and domestic banks. We show that this distribution of information about incumbent customers leads to stronger competition if foreign entry occurs through a greenfield investment. As a result, domestic bank lending rates are lower after greenfield entry. We find empirical support for this prediction for a sample of banks from 10 Eastern European countries for the period 1995–2003.     

Federal banking regulators' competition in laxity: Evidence from CRA audits

The U.S. banking industry has three federal regulators in addition to the 50 state regulators. Through choices regarding its chartering source, joining the Federal Reserve System, and having deposit insurance, a bank also selects which office or agency serves as its primary regulator. Federal regulators gain status and authority from the number of banks over which they have primary supervision. It has long been suspected, therefore, that they compete with each other to entice banks to make choices that increase the number of banks reporting to them. This competition which includes less stringent enforcement and broad interpretation of the laws as favored by the banks is known as competition in laxity. The Community Reinvestment Act (CRA) is enforced by each of the three federal banking regulators. Since 1990, their ratings of banks' CRA performance have been published. This published data provides an opportunity to test accuracy of the competition in laxity theory.     

Bank incentives, contract design and bank runs

We study the Diamond-Dybvig [Bank runs, deposit insurance, and liquidity, J. Polit. Econ. 91 (1983) 401-419] model as developed in Green and Lin [Implementing efficient allocations in a model of financial intermediation, J. Econ. Theory 109 (2003) 1-23] and Peck and Shell [Equilibrium bank runs, J. Polit. Econ. 111 (2003) 103-123]. We dispense with the notion of a bank as a coalition of depositors. Instead, our bank is a self-interested agent with a technological advantage in record-keeping. We examine the implications of the resulting agency problem for the design of bank contracts and the possibility of bank-run equilibria. For a special case, we discover that the agency problem may or may not simplify the qualitative structure of bank liabilities. We also find that the uniqueness result in Green and Lin [Implementing efficient allocations in a model of financial intermediation, J. Econ. Theory 109 (2003) 1-23] is robust to our form of agency, but that the non-uniqueness result in Peck and Shell [Equilibrium bank runs, J. Polit. Econ. 111 (2003) 103-123] is not.     

Herding in delegated portfolio management: When is comparative performance information desirable?

We address the issue of investors’ asset allocation decisions when portfolio management is delegated to an agent. Contrary to predictions from traditional financial theory, it is shown that investors may not induce their manager to allocate funds to the asset with the highest return. Instead they may herd in their asset allocation decision and induce trade in a particular asset, because another manager is trading in it and despite the presence of a more profitable alternative. Doing so allows investors to write an efficiency-improving relative-performance contract. On the other hand, herding leads investors to design wage contracts strategically, resulting in more aggressive and thus less profitable trade in equilibrium. We show that herding occurs, when the cost of information is high, information precision is low and when managers are sufficiently risk averse. Moreover, when investors can decide whether or not to disclose information about their manager's performance, they will not do so.     

Unilateral disclosure of private information by a regulated firm

It is common practice for regulators to depend on regulated firms for self-monitoring and self-reporting in spite of incentives for misrepresentation. Our analysis provides some justification for such dependence. We study disclosure of information in a game theoretic model of regulation, in which both the regulator and the firm are players in the game. Instead of designing a regulation scheme that compels disclosure, we study unilateral disclosure in a given regulatory framework (a framework which we believe has counterparts in current regulatory practice). The results provide insight to informal relationships between firms and regulators. Because the game is a single period game, the informal relationship in which the disclosures occur cannot be attributed to the existence of reputations and long term relationships.     

The impact of bank competition and concentration on industrial growth

This paper studies whether bank competition affects growth of non-banking industries. We find that non-cooperative bank competition and stability promote industrial growth robustly. Bank concentration may also affect growth positively; the latter effect increases for higher levels of competition.

Estimating bilateral exposures in the German interbank market: Is there a danger of contagion?

Credit risk associated with interbank lending may lead to domino effects, where the failure of one bank results in the failure of other banks not directly affected by the initial shock. Recent work in economic theory shows that this risk of contagion depends on the precise pattern of interbank linkages. We use balance sheet information to estimate a matrix of bilateral credit relationships for the German banking system and test whether the breakdown of a single bank can lead to contagion. We find that in the absence of a safety net, there is considerable scope for contagion that could affect a large proportion of the banking system. The financial safety net (in this case institutional guarantees for saving banks and cooperative banks) considerably reduces—but does not eliminate—the danger of contagion. Even so, the failure of a single bank could lead to the breakdown of up to 15% of the banking system in terms of assets.     

基于Merton模型的存款保险定价研究

存款保险制度的核心是存款保险费率的厘定。本文以Merton存款保险定价的看跌期权模型为基础,引入监管宽容和未保险存款的利率两个参数,给出了商业银行存款保险定价公式。选择不同的银行对其保险费率进行估算,所得的保险费率之间有一定的差距,表明不同银行的存款保险费率是不同的,中国不适合单一费率,而适合风险费率。本文对我国正在酝酿出台的存款保险制度具有一定的指导意义。
