The agency of CoCos: Why contingent convertible bonds are not for everyone

Some regulators grant contingent convertible bonds (CoCos) the status of “going-concern” capital. Theory, however, suggests that CoCos can induce debt overhang, thereby amplifying the leverage ratchet effect. In this paper, we provide empirical evidence consistent with this theory. Our results suggest that banks with more volatile assets (riskier banks) (i) are less likely to issue CoCos, (ii) conditional on having CoCos outstanding are less likely to issue equity, and (iii) prefer issuing equity over CoCos. Since riskier banks suffer from more debt overhang it is more costly for them to issue CoCos.     

Screening, Bidding, and the Loan Market Tightness

Bank loans are more available and cheaper for new and small businesses inthe U.S. in concentrated banking areas than in competitive banking areas. Weexplain this anomaly by analyzing banks' decisions to screen projects andtheir competition in loan provisions. It is shown that, by exacerbating thewinner's curse, an increase in the number of banks can reduce banks'screening probability by so much that the number of banks that activelycompete in loan provisions falls and the expected loan rate rises. This isthe case when the screening cost is low, which induces all active bidders tobe informed. The opposite outcome occurs when the screening cost is high, inwhich case there are sufficiently many uninformed banks in bidding toattenuate the winner's curse. We also examine the social optimum     

Reforming Banks Without Destroying Their Productivity and Value

Government‐protected banking systems tend to blow up, imposing huge losses on taxpayers. In a recent much‐publicized book, The Bankers' New Clothes, Anat Admati and Martin Hellwig propose to fix this problem by forcing banks to maintain 25% of their assets in the form of equity rather than debt. But this author argues, the book overstates the benefits and understates the costs of the proposed reform, while also failing to identify additional necessary reforms. Because bank equity is not true equity, and equity must be evaluated only in relation to risk, increasing required book equity ratios will not necessarily reduce the risk of bank failure significantly. Raising equity requirements is also socially costly because it reduces banks' willingness to lend. When banks need to raise their equity‐to‐asset ratios, they often choose to do so by cutting back on new loans, rather than paying the high costs of raising new equity. The reduction in loan supply that comes from raising equity ratios can be substantial, and is not just a one‐time cost. Balancing the costs and benefits of higher equity implies a much lower required equity ratio than the 25% posited in The Bankers' New Clothes. Finally, because equity ratios relative to risk should be the focus of prudential regulation, additional regulatory policy reforms that strengthen incentives for more effective risk management are needed in addition to higher capital ratios.

涉农业务边际成本过高是农村金融机构目标偏移的根本原因.依据2011-2014年湖南省87家县(市)农商行(含农信社)的经营数据,考量涉农贷款边际成本及影响因素.结果显示:微观方面,农商行的涉农贷款比重增加推高了涉农贷款的边际成本,提升资产中的贷款比重有助于降低涉农贷款边际成本,农商行的风险管理能力越强,涉农贷款的边际成本越低;宏观方面,县域金融发展水平的提升有益于降低涉农贷款的边际成本,城乡收入差距较大的县域,涉农贷款的边际成本也越高,提升县域融资市场的流动性有助于降低涉农贷款边际成本.     

Loan Sales and the Cost of Bank Capital

This paper considers a model where banks may improve the returns on loans by monitoring borrowers. Bank regulation, together with competitive deposit and equity financing, can give banks an incentive to sell loans, but the extent of their loan selling is limited by a moral-hazard problem. A solution is given for the optimal design of the bank-loan buyer contract that alleviates this moral-hazard problem. An explanation is also given as to why some banks might buy loans and why loan sales volume has recently increased.     

Evidence on the Trade-Off between Risk and Return for IPO and SEO Firms

Do the low long‐run average returns of equity issuers reflect underperformance due to mispricing or the risk characteristics of the issuing firms? We shed new light on this question by examining how institutional lenders price loans of equity issuing firms. Accounting for standard risk factors, we find that equity issuing firms' expected debt return is equivalent to the expected debt return of nonissuing firms, implying that institutional lenders perceive equity issuers to be as risky as similar nonissuing firms. In general, institutional lenders perceive small and high book‐to‐market borrowers as systematically riskier than larger borrowers with low book‐to‐market ratios, consistent with the asset pricing approach in Fama and French (1993) . Finally, we find that firms' expected debt returns decline after equity offerings, consistent with recent theoretical arguments suggesting that firm risk should decline following an equity offering. Overall, our analysis provides novel evidence consistent with risk‐based explanations for the observed equity returns following IPOs and SEOs.     

Why do bank-dependent firms bear interest-rate risk?

I document that floating-rate loans from banks, particularly important for bank-dependent firms, drive most variation in firms’ exposure to interest rates. I argue that banks prefer to supply floating-rate loans, due to their finite ability to transform short-duration deposit liabilities into long duration assets. Three key findings support this argument: banks with more floating-rate liabilities make more floating-rate loans, hold more floating-rate securities, and quote lower prices for floating-rate loans. Intermediary funding structures therefore help determine what types of contracts non-financial firms use. Banks transmit rising policy rates to firms by contractually raising interest rates on existing loans, not just by reducing the supply of new loans.     

Effect of collateral characteristics on bank performance: Evidence from collateralized stocks in Taiwan

Taiwanese law requires directors of listed firms to disclose their stocks collateralized at banks creating the possibility of examining the characteristics of collateralized stocks and their influence on bank performance. This study demonstrates that the risk (value) attributes of collateralized stocks increase (reduce) bank efficiency yet reduce (increase) bank profits. Government-owned banks but not private banks require sufficiently high margins to prevent stock loans from non-performing. Furthermore, banks charge higher interest to cover the non-performing risk. Directors who lack funds, hold high turnover stocks, and/or have weak relationships with their banks prefer to collateralize their stocks at private banks.     

Asymmetric information and price competition in small business lending

This paper examines the relationship between bank lending rates and their cost of funds in New Zealand. Our results show that on average mortgage rates respond more quickly to changes in the cost of funds than base business lending rates. We also find an asymmetry in the initial (short-run) response of banks to changes in funding costs; in particular, our results show banks adjust mortgage rates downwards faster than upwards. The speed to which lending rates revert back to their equilibrium relationship with funding costs varies across the lending markets. We find the adjustment speed is faster when mortgage rates are below equilibrium, whereas it is slower when business lending rates are above long-run levels in relation to funding costs. Our analysis suggests that banks prefer the plain-vanilla type of lending such as mortgages in comparison to small business lending consistent with asymmetric information associated with business loans.     

The bank loan distribution effect of government spending expansion: Evidence from China

Rather than focusing on the spread of enterprises' bank loans, we focus on the impact of government spending expansion on the amount of bank loans obtained by enterprises. We first build a theoretical model to show that there are the demand effect and loan cost effect of government spending expansion on the bank loans and then use the fixed effects approach to analyze the bank loan distribution effect of government spending expansion by using the data of enterprises listed on the China Stock Exchange between 2003 and 2019. Empirical results show that the demand effect plays a leading role for the central government state-owned enterprises (SOEs), helping them obtain more bank loans from banks. In contrast, for private enterprises, the loan cost effect plays a leading role, hurting them in obtaining bank loans from banks. Further research shows that government spending expansion's crowding-in or crowding-out effect differs from Neoclassicism and (new) Keynesianism. This paper provides a new explanation for why the financing problem of private enterprises is getting worse in China. The policy implication is that when the government implements expansionary fiscal policies, it should also provide convenience for private enterprise financing through window guidance to prevent the expansionary fiscal policies from crowding out private enterprise bank loans.     

Are Banks Still Special When There Is a Secondary Market for Loans?

Secondary market trading in loans elicits a significant positive stock price response by a borrowing firm's equity investors. We find the major reason for this response is the alleviation of borrowing firms’ financial constraints. We also find that new loan announcements are associated with a positive stock price effect even when prior loans made to the same borrower already trade on the secondary market. We conclude that the special role of banks has changed due to their ability to create an active secondary loan market while simultaneously maintaining their traditional role as information producers.     

Bad luck or bad management? Emerging banking market experience

A large number of bank failures occurred in transition countries during the 1990s and at the beginning of the 2000s. These were related to increases in non-performing loans and deteriorated cost efficiency of banks. This paper addresses the question of the causality between non-performing loans and cost efficiency in order to examine whether either of these factors is the deep determinant of bank failures. We extend the Granger-causality model developed by [Berger, A., DeYoung, R., 1997. Problem loans and cost efficiency in commercial banks. J. Banking Finance 21, 849–870] by applying GMM dynamic panel estimators on a panel of Czech banks between 1994 and 2005. Our findings support the bad management hypothesis, according to which deteriorations in cost efficiency precede increases in non-performing loans. Banking supervisors should consequently focus on enhanced cost efficiency of banks in order to reduce the likelihood of bank failures in transition countries.     

Subordinated Debt,Market Discipline,and Bank Risk

This paper demonstrates that subordinated debt (subdebt thereafter) regulation can be an effective mechanism for disciplining banks. By reducing the chance that managers of distressed banks can take value‐destroying actions to benefit themselves, subdebt regulation may encourage banks to lower asset risk. Moreover, subdebt regulation and bank capital requirements can be complements for alleviating the banks’ moral hazard problems. To make subdebt regulation effective, regulators may need impose ceilings on the interest rates of subdebt, prohibit collusion between banks and subdebt investors, and require subdebt to convert into the issuing bank's equity when the government provides assistance to the bank.     

Corporate Taxes and Securitization

Most banks pay corporate income taxes, but securitization vehicles do not. Our model shows that, when a bank faces strong loan demand but limited deposit market power, this tax asymmetry creates an incentive to sell loans despite less‐efficient screening and monitoring of sold loans. Moreover, loan‐selling increases as a bank's corporate income tax rate and capital requirement rise. Our empirical tests show that U.S. commercial banks sell more of their mortgages when they operate in states that impose higher corporate income taxes. A policy implication is that tax‐induced loan‐selling will rise if banks’ required equity capital increases.     

The role of securitization in bank liquidity and funding management

This paper studies the role of securitization in bank management. I propose a new index of “bank loan portfolio liquidity” which can be thought of as a weighted average of the potential to securitize loans of a given type, where the weights reflect the composition of a bank loan portfolio. I use this new index to show that by allowing banks to convert illiquid loans into liquid funds, securitization reduces banks' holdings of liquid securities and increases their lending ability. Furthermore, securitization provides banks with an additional source of funding and makes bank lending less sensitive to cost of funds shocks. By extension, the securitization weakens the ability of the monetary authority to affect banks' lending activity but makes banks more susceptible to liquidity and funding crisis when the securitization market is shut down.     

Financial Reporting Quality,Debt Maturity,and the Cost of Debt: Evidence from China

This paper investigates the influence of different financing channels—bond issuance or bank loans—as well as debt maturity and the quality of financial reporting on the cost of debt in China. The authors find that conservative accounting is an important characteristic of high-quality financial reporting that can reduce the cost of longer maturity debt such as bank loans and bonds. Even state-owned enterprises, which have fewer financial constraints than non-state-owned enterprises, benefit from accounting conservatism's ability to reduce financial costs. Moreover, the findings indicate that bond investors are concerned about the issuer's fundamentals, while banks are more likely to focus on the operation and bankruptcy risk of borrowers.     

Inefficient liquidity creation

We present a model in which intermediaries create liquidity by issuing safe debt. Two types of intermediaries emerge: Traditional banks that create liquidity by issuing equity and holding assets to maturity, and market-based intermediaries that create liquidity by selling assets in fire sales in downturns. We show that the reliance on market-based intermediation is necessarily too high, but liquidity creation is not. It can also be too low as the endogenous fire-sale risk can push liquidity creation below its optimum. We argue that standard capital or liquidity regulation are ineffective, and optimal macroprudential regulation should instead target market-based intermediation.     

The impact of all-star analyst job changes on their coverage choices and investment banking deal flow

Using a sample of all-star analysts who switch investment banks, we examine (1) whether analyst behavior is influenced by banking relationships and (2) whether analyst behavior affects investment banking deal flow. Although the stock coverage decision depends on the relationship with the client firms, we find no evidence that analysts change their optimism or recommendation levels when joining a new firm. Investment banking deal flow is related to analyst reputation only for equity transactions. For debt and M&A transactions, analyst reputation does not matter. There is no evidence that issuing optimistic earnings forecasts or recommendations affects investment banking deal flow.     

Exploitation of the internal capital market and the avoidance of outside monitoring

Internal capital markets (ICMs) provide firms an alternative to costly external financing; however, they also provide an avenue to avoid the monitoring associated with issuing external capital. We argue that firms operating inefficient internal capital markets will avoid outside financing. Consistent with this view, conglomerates that cross-subsidize divisions or engage in value-destroying investment avoid external capital market oversight by refraining from issuing both debt and equity. We further show that firms issuing bonds while engaging in value-destroying investment experience yield spreads that are, on average, 46 basis points higher than those of other diversified firms. They similarly experience yield spreads that are 18 basis points higher when they issue syndicated loans. Value-destroying conglomerates also witness SEO announcement returns that are, on average, 1% more negative than firms operating more efficient internal capital markets.     

赶超战略与大银行垄断——基于新结构经济学的视角

改革开放初期,中国有很多资本高度密集的大型国有企业,需要大量资金维持生产运营,若无法获得足够的银行贷款以致资金链断裂而破产倒闭,极易引发动荡。本文研究发现,在当时中国资本稀缺的要素禀赋结构下,为确保“重要而不能倒”的国有企业获得足够的银行贷款而不破产倒闭,不适合采用放开银行准入以促使银行竞争的方式,反而应限制银行准入,控制银行数量。原因在于,放开银行准入增加的仅是中小银行,其资金动员能力有限,与国有企业的规模特性不相匹配,更重要的是,大量中小银行进入会分流大银行的存款,降低大银行的资金动员及服务国有企业的能力,导致国有企业的贷款成本和破产风险因此而上升。本文指出,一个国家的银行业结构内生于该国的经济发展战略。限制银行准入的政策安排通过在金融方面支持国有企业,在改革初期起到了维护国防安全、保障国计民生和维持社会经济稳定的作用,为平稳推动改革创造了条件。
