Over-the-counter loans,adverse selection,and stigma in the interbank market

We study a model of interbank credit where physical and informational frictions limit the opportunities for intertemporal trade among banks and outside investors. Banks obtain loans in an over-the-counter market (involving search, bilateral matching, and negotiations over the terms of the loan) and hold assets of heterogeneous quality that in turn determine their ability to repay those loans. When asset quality is not observable by outside investors, information about the actions taken by a bank in the loan market may influence prices in the asset market. In particular, under some conditions, borrowing from the central bank can be regarded as a negative signal about the quality of the borrower?s assets and banks may be willing to borrow in the market at rates higher than the one offered by the central bank.     

Two stages credit evaluation in bank loan appraisal

Traditionally, banks conduct standard credit evaluation such as credit scoring following the receipt of loan request and make the accept/reject decision accordingly. This research explores the possibility of two stages credit evaluation in lending process. When the evaluation cost drops below the trigger cost, it pays to conduct the second-stage loan appraisal. We derive two trigger cost thresholds for borrowers who are rated as credible and default in the first stage, respectively. Contingent on the share of good borrowers relative to the bad ones, the optimal strategy of the bank can be differentiated to implement second-stage evaluation on either (1) both types, or (2) only one type, or (3) neither type of the borrowers. We find that during severe economic contractions or in geographic areas/industries which are in deep troubles, whilst the borrowers who repay the loan are out-numbered by the borrowers who fail to pay, the trigger cost for good borrower is higher than that of default borrower. In this scenario, the banks are more inclined to undertake the second-stage credit evaluation on good borrowers. On the other hand, if the percentage of credible borrowers is higher than that of default borrowers, the trigger cost for good borrower lies below the trigger cost of default borrower. As a result, the banks are less inclined to undertake the second-stage evaluation on good borrowers.

Democracy favors access to credit of firms

Access to credit is one of the main obstacles for the growth of firms. We test the hypothesis that democracy exerts an impact on access to credit. We perform regressions at the firm-level on a large dataset of 46,000 firms in 108 countries. We find evidence of a negative relationship between democracy and credit constraints for firms. We further establish that democracy contributes to reduce borrower discouragement and leads to more bank loan approval decisions. Our key finding is therefore that democracy favors firms' access to credit. Our work contributes to the debate on the impact of democracy on economic development by considering one firm-level channel of transmission.     

Regulating Exclusion from Financial Markets

We study optimal enforcement in credit markets in which the only threat facing a defaulting borrower is restricted access to financial markets. We solve for the optimal level of exclusion, and link it to observed institutional arrangements. Regulation in this environment must accomplish two objectives. First, it must prevent borrowers from defaulting on one bank and transferring their resources to another bank. Second, and less obviously, it must give banks the incentive to make sizeable loans, and to honour their promises of future credit. We establish that the optimal regulation resembles observed laws governing default on debt. Moreover, if debtors have the right to a "fresh start" after bankruptcy then this must be balanced by enforceable provisions against fraudulent conveyance. Our optimal regulation is robust, in that it can be implemented in a way that does not require the regulator to have information about either the borrower or lender. Our results isolate the way in which specific institutions surrounding bankruptcy–namely rules governing asset garnishment and fraudulent conveyances–support loan markets in which borrowers have no collateral.     

A Theory of Conflicts of Interest in Banking Relationships

Abstract

This paper highlights a dark side of banking relationships by elucidating the conditions under which a pre-existing relationship between a lending bank and a borrower can be detrimental to positive valuation effects of loan announcements. The effect of a pre-existing relationship is more likely to be negative when the pre-existing loans are large and firms' screening costs are low. A theoretical model shows that loan announcement's positive effect on borrowers' value due to the standard information advantage can be more than offset by the bank's conflict of interest when the bank's asset quality reputation is poor, i.e. when the probability of the bank holding a bad loan is large.     

Information sharing and the volume of private credit in transition: Evidence from Ukrainian bank-level panel data

The effect of lenders' information sharing on the volume of credit is ambiguous in theory and underexplored empirically. Departing from the scant existing literature, which draws on country-level aggregate data, we study the impact of information sharing on the volume of private credit by examining unique bank-level panel data from Ukraine, a transition economy where information sharing among banks is only a recent phenomenon. Employing the fixed-effects framework and dynamic panel methods to address endogeneity due to the non-exogenous nature of banks' choice to participate in information sharing, we find no credit volume effect of information sharing when information sharing takes place through the central bank-administered public credit registry. In contrast, information sharing through private credit bureaus is associated with an increase in the volume of bank lending, in particular when a bank is partner of multiple private credit bureaus. This effect is robust and non-negligible in magnitude.     

The effect of lender and loan type on a borrowing firm’s equity return

Past empirical studies appear to support the idea that banks and finance companies do not differ in their ability to resolve adverse selection problems associated with issuing new debt. In this article, we find there is a difference. More specifically, using an event study we find larger abnormal returns for secured loan disclosures to lower quality borrowers when the lender is a finance company versus a bank. This suggests the market views finance companies as more effective than banks in evaluating/monitoring lower quality borrowers obtaining secured loans. We posit this is due to finance companies’ greater expertise in this type of lending, resulting from specialization. Our findings extend the literature on how lender identity can influence signals about firm value from loan disclosures. Our results also support recent findings that positive abnormal returns to borrowing firms may not be a general feature across the loan population, but may be restricted to smaller, lower quality borrowers. Finally, we are the first to provide evidence that the market takes loan type into account, not just lender and borrower type, when considering the information embedded in loan disclosures.     

Determinants of banks’ Nerlovian economic efficiency: a DEA-bootstrap approach

ABSTRACT

This study aims to evaluate the Nerlovian economic efficiency of Taiwanese commercial banks and its determinants by assuming the presence of an imperfectly competitive market using a two-stage estimation procedure: Nerlovian economic inefficiency and its components’ price, technical and allocative efficiencies computed and decomposed in the first stage, which are regressed on the explanatory variables with a bootstrapped truncated approach in the second stage. The estimation results show that in the first-stage analysis, the Nerlovian economic inefficiency of banks is primarily due to allocative inefficiency, and indicate the existence of price inefficiency in Taiwan. In the second-stage analysis, the results confirm that both the years in operation of the bank and the ratio of credit loans are the main determinants of banking profit efficiency. In addition, this study not only shows that publicly owned banks contribute to better price efficiency but also proves that loan loss reserve to total assets is negatively associated with technical efficiency. The equity ratio exerts an insignificant favourable impact on allocative efficiency. The findings of this research are essential for bank managers in Taiwan.     

金融危机背景下政府干预与银行信贷风险研究

金融危机冲击导致经营环境恶化,银行信贷萎缩,在政府施加的指令性贷款和自身经营利润最大化的双重任务约束下,银行道德风险增加,贷款资金投放背离政府救市意图。文章在一个双重任务约束模型框架下分析了危机中政府干预对国有商业银行贷款风险的影响,根据任务之间的关联度对银行的激励行为做出拓展性解释。动态面板GMM模型实证检验结果显示,政府干预没有造成不良贷款的上升,但对信贷规模的扩张存在明显影响,长期将造成银行资源的过度利用和潜在风险的上升。     

Bank efficiency in South‐Eastern Europe

This study examines the cost and profit efficiency of banking sectors in six transition countries of South‐Eastern Europe over the period 1998–2008. Using a stochastic frontier approach, our analysis reveals that the average cost efficiency of South‐Eastern European banks is 68.59 percent, and the average profit efficiency is 53.87 percent. Regressions on the determinants of bank efficiency show that foreign banks are characterized by higher profit efficiency but lower cost efficiency, and government‐owned banks are associated with lower profit efficiency than domestic private banks. However, the efficiency gap between foreign‐, domestic private‐ and government‐owned banks narrows over time. We also find that the market power of a bank has a positive association with both cost and profit efficiency. Institutional development, proxied by progress in banking regulatory reforms, privatization and enterprise corporate governance restructuring, also has a positive impact on bank efficiency.     

The bank lending channel of unconventional monetary policy: The impact of the VLTROs on credit supply in Spain

We assess the impact on the credit supply to non-financial corporations of the two very long term refinancing operations (VLTROs) conducted by the Eurosystem in December 2011 and February 2012 for the case of Spain. To do so we use bank–firm level information from a sample of more than one million lending relationships during two years. Our methodology tackles three main identification challenges: (i) how to disentangle credit supply from demand; (ii) the non-random assignment of firms to banks; (iii) the endogeneity of the VLTRO bids, as banks with more deteriorated funding conditions were more likely both to ask for a large amount of funds and to restrain credit supply. Our findings suggest that the VLTROs had a positive moderate-sized effect on the supply of bank credit to firms. We also find that the effect was greater for illiquid banks and that it was driven by credit to SMEs, as there was no impact on loans to large firms. By contrast, strong firm–bank relationships were less sensitive to the positive liquidity shock caused by the VLTROs, which is consistent with the studies that find that relationship lending is a more stable source of credit than transaction lending. Finally, the VLTROs had no impact on either the degree of loan collateralisation or the probability of making loans to new borrowers, while they decreased the probability of renewing old ones, which suggests that those funds were not used for loan “evergreening”.     

The Credit Channel at Work: Lessons from the Financial Crisis in Korea

We demonstrate that the credit channel of transmission of monetary/financial shocks appears to have aggravated Korea's economic crisis. We use micro-data gathered at the individual bank level to identify this channel of transmission. Our major findings are as follows: i) consistent with banks' autonomous retrenchment in loan supply, monetary tightening broadens the spread between marginal bank lending rates and corporate commercial paper rates; ii) credit limits on overdrafts – arguably a proxy identifying shifts in loan supply – react negatively to the monetary squeeze; iii) large negative capital shocks induce banks to disproportionately slow-down both lending and deposit taking and to disproportionately raise their lending rates. Our findings lend unequivocal support to the hypothesis that banks' autonomous contraction restricted the availability of credit and magnified the increase in its cost. In turn, this compounded the Korean crisis by aggravating liquidity constraints for the vast majority of agents who rely only on bank credit as an external source of funds.     

Firm size,credit scoring accuracy and banks’ production of soft information

Research on SME bank financing generally assumes that smaller firms are more opaque from a lender’s perspective. We propose that the discriminatory power of credit scoring models can be thought of as a proxy for firm opaqueness, given that when these models perform poorly, lenders must invest in the production of ‘soft information’ to supplement the financial data used in these models. Measuring the discriminatory power of probit default models across quintiles of the Irish SME size distribution, we show that our proxy for firm opaqueness increases monotonically as firms get smaller. This finding supports an assumption that is the starting point to a wide strand of literature on SME bank financing. Our findings can also be interpreted as providing an insight to the literature on the determinants of banks’ choice of lending technology. While smaller banks may, as found in a substantial previous literature, produce larger amounts of ‘soft information’ due to their organizational advantages, they may also do so out of necessity: hard-information-based default modelling is less effective among smaller firms, thereby forcing banks that lend to these borrowers to invest more in relationship banking technologies to retain competitiveness.     

问询函监管与银行信贷决策的改善*

近年来,证券交易所推行的问询函监管逐渐成为保障和改善上市公司信息披露质量的重要机制,其实施效果自然成为监管者和学者关注的焦点。本文从银行的角度研究问询函监管对外部利益相关者的溢出效应,具体考察问询函监管对银行信贷决策的影响。研究发现,在公司被出具问询函后,银行的贷款利率显著更高,贷款期限显著更短,银行贷款要求提供担保的可能性和比例更高。进一步研究发现,当公司处于信息风险和信用风险相对较高的情境中,或银行对信息风险和信用风险较为关注的情况下,银行贷款利率上升幅度更加显著,不过,贷款期限、担保要求等非价格条款并没有显著差异。同时,问询函对银行信贷决策的影响在银企之间存在较强的信息不对称时更加显著。最后,本文发现公司收到问询函以后,分析师预测分歧度显著提高,这表明信息风险是问询函监管影响银行信贷决策的一个可能渠道。     

Do government owned banks trade market power for slack?

The ‘Quiet Life Hypothesis (QLH)’ posits that banks with market power have less incentives to maximize revenues and minimize cost. Especially government owned banks with a public mandate precluding profit maximization might succumb to a quiet life. We use a unified approach that simultaneously measures market power and efficiency to test the quiet life hypothesis of German savings banks. We find that average local market power declined between 1996 and 2006. Cost and profit efficiency remained constant. Nonparametric correlations are consistent with a quiet life regarding cost efficiency but not regarding profit efficiency. The quiet life on the cost side is negatively correlated with bank size, quality of loan portfolio and local per capita income. The last result indicates that the quiet cost life is therefore potentially due to benevolent excess consumption of local input factors by public savings banks.     

The effect of economic policy uncertainty on bank valuations

This article examines how economic policy uncertainty (EPU) affects bank valuations. Using a large sample of banks over a long period, we find that EPU has a negative effect on bank valuations. One explanation for this result is that EPU reduces bank loan growth, and lower loan growth then leads to lower bank valuations. Consistent with this explanation, we find that the negative effect of EPU is more pronounced for banks with a higher ratio of loans to total assets.     

金融危机、货币政策与信贷供给*——基于公司层面银行信贷数据的经验研究

不同的银行特征会对金融危机和货币政策传导的银行信贷渠道产生异质性影响。本文运用2001-2015年公司层面银行信贷数据实证检验了我国货币政策传导的银行信贷渠道,随后进一步研究金融危机对不同特征银行信贷供给的影响差异。经验研究发现：我国货币政策银行信贷渠道主要通过非国有控股银行传导,并引起不同资产负债表特征银行信贷供给的异质性反应。银行规模越大、流动性越强、资本充足率越高,银行信贷供给对货币政策越不敏感。金融危机期间,银行信贷渠道的传导效率显著降低,高资本充足水平的银行和国有控股银行受金融危机的冲击较小,并且宽松的货币政策对国有控股银行信贷供给调控的效率更高。     

Interest rate pass-through in Morocco: Evidence from bank-level survey data

We investigate the relationship between banks’ marginal cost and retail lending rates in Morocco. The data covers the rates of new business loans for four market segments broken down by institutional sector between 2006Q2 and 2016Q4. We examine the pass-through mechanism using recently developed heterogeneous panel cointegration framework. Our findings suggest that there is a high degree of pass-through heterogeneity over bank products. The weak adjustment for short-term credit facilities and consumption loans can be explained by credit risk compensation allowing banks to reduce their exposition to systemic risks. Corporate loans are priced more competitive than household and individual entrepreneur products, suggesting that negotiation power or the competition from the borrower side matters. Overall, our results indicate that banking market contestability has improved during the last decade.     

Strategic default and optimal audit resources with costly state verification

I develop a model in which the ability to repay a loan is private information that can only be verified by the bank at some costs, which can be recovered from the borrower if it has reported untruthfully. The bank will optimize the resources it spends on this auditing of borrowers and the resulting equilibrium is then characterized. It is shown that in equilibrium, a significant fraction of companies default strategically, but most are captured via auditing. The failure rates of banks are also small. Finally extensions are discussed to include limited liability to banks and the partial recovery of auditing costs as well as punitive costs to borrowers.
