Counterfactual analysis of bank mergers

We introduce a counterfactual analysis of banks mergers, combining the pre-merger equilibrium setting with post-merger environmental characteristics, while accounting for endogenously propagated changes in market structure. Using this procedure we are able to estimate the effects on loan flows and interest rates that would have been observed if the pre-merger equilibrium was not altered. Results are obtained for firms, households, and banks inside and outside the merging circles separately. We find that mergers increased firms’ access to credit, but had an opposite effect on households and led to a widespread decrease in interest rates.     

货币政策能否促进银行对小微企业信贷投放——基于宏观经济不确定视角的研究

本文研究在宏观经济不确定条件下,不同货币政策工具能否促进银行对小微企业信贷投放。首先,将货币政策引入考虑了宏观经济不确定性的银行资产组合模型中,论证货币政策、宏观经济不确定性与银行信贷资产配置的理论关系。然后利用我国181家银行2004—2018年的数据,检验在宏观经济不确定条件下,不同货币政策工具对银行小微企业信贷行为调控的作用效果。研究结果表明：宏观经济不确定性会抑制银行信贷行为。其中小微企业信贷占比较大的银行受到的影响更为显著。与数量型货币政策相比,价格型货币政策能够更显著地减轻不确定性对银行小微信贷的消极影响。其中银行同业拆借利率的调控效果最强。研究结论对于选择适宜的货币政策工具促进银行向小微企业信贷投放,化解经济不确定性对银行信贷行为的影响并助力小微企业发展等具有政策借鉴意义。     

非对称信息条件下信贷市场分析

随着市场机制的建立和金融体制改革的深入,企业与银行之间的借贷关系日益复杂,银行对企业的放贷面临新的挑战。企业为了获得贷款想方设法隐瞒自己信息,银行为了避免损失,极力加强监管力度。由于商业银行(放款者)与企业(贷款者)之间存在着信息不对称性,所以它直接影响银行的贷款风险决策。     

Meltdown Iceland: Lessons on the World Financial Crisis from a Small Bankrupt Island

The paper reports that no statistically significant empirical relationship can be shown between total bank credit and the US broad money supply in the period after 1995. It argues that the growing prevalence of non-bank deposits in the form of mutual money market funds and asset securitization are the main culprits for this result. Prior to financial liberalization, the connection between total bank credit and broad money supply was simple enough: new bank deposits were created when banks made loans and were extinguished when loans were paid back. In banks' consolidated balance sheet, total deposits made up total liabilities and were basically equal to the broad money supply. However, in the age of financial liberalization not all deposits bank loans created returned as deposits, whether in banks or non-banks, as deposits could be swapped for non-deposit liabilities without a corresponding draw down on the asset side. Moreover, loans could be extinguished in banks' balance sheets through asset securitization.     

The role of banks in the Czech monetary policy transmission mechanism

With this work, I aim to enrich the knowledge about the monetary policy transmission mechanism in the Czech Republic with empirical evidence on the impact of monetary policy on bank lending. Using a panel of quarterly time series for Czech commercial banks for the period 1996–2001, I study the overall effect of monetary policy changes on the growth rate of loans and the characteristics of the supply of loans. The characterization of the credit market's supply side allows us to make inferences on the operativeness of the credit channel (the bank lending channel and the broad credit channel) of the monetary transmission mechanism. I find that changes in monetary policy alter the growth rate of loans, with considerably stronger magnitude in the period 1999–2001 than in the period 1996–1998. From the analysis intended to capture the characteristics of the supply of loans, I conclude that the lending channel was operative in the period 1996–1998: I find cross‐sectional differences in the lending reactions to monetary policy shocks due to the degree of capitalization and to liquidity. For the subsequent period 1999–2001, the results also show distributional effects of monetary policy due to bank size and its bank's proportion of classified loans. In the context of steadily decreasing interest rates, this can bolster the supposition of financial frictions between borrowers and lenders and hence, that of an operative broad credit channel.     

Why the money multiplier has remained persistently so low in the post-crisis United States?

The money multiplier collapsed in the USA in the wake of the Lehman crisis, and since then it remained at particularly low levels. The main reason for this collapse is to be found in the significant increase in banks’ excess reserves and the modest increase in deposits. The weak growth of deposits resulted from a contained growth of loans. Most scholars attribute the latter to the low propensity of banks to grant credit. Using quarterly data for the period 1991–2017 we estimate a demand for loans by firms and households. We show that the modest increase in deposits and the persistence of low levels of the US money multiplier has been due to the weak demand for loans by the private sector.     

数字金融发展能否在农村金融市场发挥“鲶鱼效应”*——来自中国农信机构的证据

本文从农信机构贷款支农的角度出发，探究数字金融能够在多大程度上促进市场竞争，进而在农村金融市场发挥“鲶鱼效应”。理论部分基于市场势力假说，分析了数字金融发展对农信机构放贷行为的影响；实证部分将北京大学数字普惠金融的县级指数与县域农村信用社、农村商业银行的贷款数据相结合，对理论假说进行了检验。结论如下：第一，数字金融发展能够激励当地农信机构提升涉农贷款和农户贷款的投放规模和增长速度，表明数字金融在农村金融市场上发挥了“鲶鱼效应”。第二，数字金融发展对农信机构支农力度的正向影响主要来源于竞争激励机制，而现阶段数字金融难以在技术上对农信机构起到示范作用。第三，进一步讨论发现，数字金融发展还有助于降低农信机构的贷款利率，让更多的涉农主体享受到利率更低的信贷服务，真正推动农村正规金融服务的“普”和“惠”共同实现。     

A QUEST FOR UNFETTERED CREDIT: HOW MONETARY POLICY DRIVES CREDIT RISK TRANSFER OF STRUCTURED FINANCE PRODUCTS

This study examines the effects of monetary policy contractions on bank loans to households and firms and instruments in three different credit risk transfer (CRT) capital markets over two separate time periods (1995–2006 and 2007–2015). The findings show that in both periods, banks decrease business lending but increase lending to consumers through a combination of mortgage, auto, credit card, and student loans from more liquidity produced by consumer‐related CRT activity. Additional results reveal relative CRT movements toward securitized mortgages from bank mortgage debt over both periods and toward securitized and insured business loans from bank business debt in the latter period, which suggest vulnerabilities among interconnected credit markets.

Bank versus nonbank financial institution lending behaviour: indictors of firm size,risk or ownership?

Using 1251 matched commercial loan deal terms of listed companies over the period 2003–2014, we examine the heterogeneity of lending behaviours of bank and nonbank financial institutions. The results show that large firms have a higher likelihood of getting loans from nonbank financial institutions. Compared to banks, nonbank financial institutions are more likely to provide credit help to high operation risk firms. State-owned listed firms have a higher probability to get finance from nonbank financial institutions than private firms, which highlights the situation that private firms are in a weak position to get credit help from China’s financial system. Moreover, the process of increasing the banks’ noninterest income ratio tends to drives firms to borrow from nonbank financial institutions.     

Microfinance spillovers: A model of competition in informal credit markets with an application to Indian villages

Despite widespread interest in the development of microfinance, spillover effects on the non-using population and redistributive issues remain largely unexplored. I study a competition game between microfinance institutions (MFIs) offering joint-liability loans and moneylenders offering individual loans in presence of adverse selection. I show that one unintended consequence of the entry of a microfinance sector in local credit markets can be to trigger an increase in the equilibrium informal interest rate, because MFIs tend to attract a disproportionately-safe share of the borrower pool away from incumbent moneylenders. The existence of such composition externality depends crucially on the size of the microfinance sector and the risk composition of the borrower pool. The model predicts a non-linearly increasing relationship between informal interest rates and MFIs' capacity in relatively safe credit markets, and no relationship in risky villages. I show evidence supporting these predictions, using a first-hand panel database that records all credit transactions over 8 years for a sample of about 1000 households living in Indian villages with extensive space and time variation in the size of their microfinance sector.     

银行效率与不良贷款冲击效应的实证研究——基于SFA测度分析的应用

本文以1999～2010年12年间国内14家商业银行样本数据为基础,立足于随机前沿效率分析原理,利用参数估计SFA分析法,评估分析金融改革以来银行业不良贷款与银行效率分布及演化趋势。研究表明:(1)是否引入不良贷款变量对银行成本效率测算存在显著影响。(2)在引入不良贷款的估计模型中,国有商业银行成本效率存改善趋势,否则,呈下降趋势,而股份制商业银行则无此特点;股份制银行成本效率整体高于国有商业银行。(3)未发现资产规模、权益与银行成本效率之间的显著性相关关系,但不良贷款对成本效率具有负效应。(4)在中国银行业利润效率测算中,则不适合引入不良贷款变量。     

我国银行信贷与房地产价格关系研究

文章对银行信贷与房地产价格之间的互动关系进行了完整的作用机制分析,并使用更细致和精确的数据建立VAR模型进行了实证研究。研究发现,银行信贷扩张与房地产价格上涨具有明显的相互推动和加强的作用。具体而言,房地产开发商贷款和个人购房贷款对房价都具有显著的正向影响,同时对来自房价冲击的响应也都是正向的。并且,在房价持续高速上升时期,房地产贷款规模对房价的影响力明显超过贷款利率。     

Creditor passivity: The effects of bank competition and institutions on the strategic use of bankruptcy filings

In transition countries, banks often fail to take action against loan defaulters. Using a model of the bank–firm relationship, we study the trade-off a bank faces when having defaulting firms declared bankrupt. First, the bank receives a payoff if a firm is liquidated. Second, it provides information about a firm’s type to its competitors. Therefore, asymmetric information between banks is reduced, and bank competition intensifies. We find that the better the institutions and the more competitive the banking sector, the greater the bank’s incentive to bankrupt defaulting firms. This makes information between banks less asymmetric and thus leads to lower interest rates and increases the probability that all banks offer loans.

The Macroeconomic Implications of Regulatory Capital Adequacy Requirements for Korean Banks

The capital adequacy requirement, combined with the flight to quality, contributed to a drastic credit slowdown and a sharp recession in Korea in the aftermath of the financial crisis. Since most banks were placed under the strengthened capital adequacy constraints, they reduced loans to firms with high credit risks. As a result, bank-dependent small and medium-sized enterprises (SMEs) were badly hit, and eventually demand for bank loans fell. The reduction in loans was most visible among banks with poor capital adequacy, yet the overall change in bank portfolios had a disproportionately large negative influence on financial conditions for SMEs. In conclusion, the banks' response to capital adequacy requirements resulted in changes in the loan/bond ratio which, in turn, reduced loans to SMEs and caused a sharp cut in production. The resulting contraction in SME production created a polarized industrial structure and a chronic depression in the traditional sectors of the economy. The introduction of capital adequacy requirements (CARs) in the wake of financial crisis worsened conditions for SMEs and weakened the validity of the CARs that were mainly necessitated by successive failures among larger firms.     

Credits and non-interest rate determinants of loan demand: a Spanish case study

This article uses bivariate probit analysis to model the potential relationship between the condition of being credit-unconstrained and holding loans as well as to ascertain determinants of a household being credit-unconstrained and likely holding consumer and real-estate loans. It documents that family size, education, permanent and transitory incomes, among others, affect Spanish households’ desire and capacity to hold loans. Furthermore, these factors were found to affect demands for real-estate and consumer loans differently. In general, the above and other results from this research provide insights that would interest credit consumers, credit suppliers, and policy makers in Spain.     

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”.     

Analyzing the role of mutual guarantee societies on bank capital requirements for small and medium-sized enterprises

This paper analyzes the impact of the guarantee provided by mutual guarantee societies (MGSs) on the risk premium that banks should charge for small- and medium-sized enterprise (SME) loans under the new Basel Capital Accords (Basel II and III). We also examine whether the foreseeable decrease in the theoretical credit risk premium would be compensated by the cost of the MGS guarantee. To do so, we develop a rating system for SMEs that uses a large sample of Spanish firms over the period from 2005 to 2009. We find that the final effect of the guarantee on the SME risk premium depends on the values taken by the credit variables of the MGS (essentially, the probability of default).     

垄断型信贷市场融资担保问题分析--以民营中小企业融资为例

民营中小企业在转型经济条件下的垄断型信贷市场中很容易受到信贷歧视,商业银行对此类企业的"惜贷"乃至拒贷不仅反映出非公有制经济主体差强人意的融资地位,而且从一个侧面折射出计划金融体制对于商业银行市场化改革的种种束缚作用以及在金融改革滞后的情况下商业银行信贷行为的严重不合理性.本文试图通过建立一个垄断型信贷市场融资担保模型来分析市场垄断和利率管制对民营中小企业融资的不利影响,担保对于缓解民营中小企业融资难问题所能发挥的积极作用,以此说明改革我国金融体制、开放信贷市场和实行利率自由化的必要性.     

Causal Effect of Credit Guarantees for Small- and Medium-Sized Enterprises: Evidence from Italy

We evaluate the effectiveness of a partial credit guarantee program, implemented in a large Italian region, that aimed to improve the access to credit of small and medium enterprises. Using unique microdata from a broad set of firms, we show that the policy increased the long-term loans for beneficiary firms, while the total volume of bank loans was unaffected. Furthermore, targeted firms benefited from a substantial decrease in interest rates. However, there is some evidence that firms are more likely to default as a consequence of the treatment. Conversely, the results do not point to any significant effect on investments.
