Public initiatives to support entrepreneurs: Credit guarantees versus co-funding

We analyze financial support for the entrepreneurial sector. State support can raise welfare by relaxing financial constraints, but it can also reduce lending standards if entrepreneurs substitute public sources of collateral for their own assets, if it encourages excessive entrepreneurial entry, or if it undermines bank monitoring incentives. We derive a “pecking order” for support schemes: support funds should be channeled first to credit guarantee schemes and then, when entrepreneurs start to substitute public for private collateral, to co-funding entrepreneurial projects. The optimal level of credit guarantee is diminishing in the costs of incentivising bank monitoring. We show in an extension that the long-term effect of public subsidies may be to impair the private sector’s initiative to uncover cost savings.     

Credit line takedown and endogenous bank capital

This paper investigates the implications of the uncertain timing and usage of loan commitments for the optimal level of bank capital. We use trended Brownian motion to proxy the stochastic takedown of credit lines. Relying on “time to first passage” mathematics, we derive a probability density function for the time to depletion of the bank credit line as well as the likelihood for the time to exhausting the sources of liquidity that fund the loan takedown. Armed with these analytical results, we solve for the optimal level of bank capital within a simultaneous equation framework in order to capture the interrelationships of the endogenous variables. The optimality conditions produce a system of integral differential equations which refuse to yield reduced form solutions and provide no immediate intuition. Therefore, the maximizing values of the bank’s decision variables were simulated over a host of realistic scenarios. We document the comparative static behavior of the bank’s decision variables when equity is unencumbered by capital requirements and, also, examine the impact of the same parametric changes on bank behavior when equity is a fixed proportion of lending. Further simulations produce the expected time to liquidity depletion under different capital requirement schemes.     

The conditioning role of performance on the bank risk-taking channel of monetary policy: Evidence from a multiple-tool regime

The study investigates how monetary policy affects bank risk-taking under a multiple-tool regime of Vietnam during 2007–2018. Particularly, we also consider the conditioning role of bank performance, broken down by bank profitability and cost efficiency, in this nexus. Using both dynamic and static panel models, we show that the liquidity injection initiated by the central bank’s asset purchases induces banks to take more risks, captured by the traditional Z-score and two alternative measures of credit risk. However, monetary policy easing through decreased interest rates is beneficial to the credit portfolio and financial stability of banks, which therefore challenges the functioning of the bank risk-taking channel. This startling result is robust across three different interest rate measures, including lending rates, refinance rates and rediscount rates. Further analysis reveals that our observed effects are alleviated for banks with higher performance — i.e., more profitable and efficient banks. This in-depth finding offers more insights into the “search for yield” incentive, based on the theory of information asymmetry and the two competing hypotheses of “bad management” and “cost skimping”.     

Are lending relationships beneficial or harmful for public credit guarantees? Evidence from Japan's Emergency Credit Guarantee Program

This paper examines the effectiveness of Japan's Emergency Credit Guarantee (ECG) Program set up during the financial turmoil following the failure of Lehman Brothers, in increasing credit availability and improving the ex-post performance of small businesses. In particular, using a unique firm–bank matched dataset, the paper examines whether lending relationships enhanced or dampened the effects of the ECG program. It is found that the ECG program significantly improved credit availability for firms using the program. However, when it was a relationship lender (main bank) that extended an ECG loan, the increased availability was partially, if not completely, offset by a decrease in non-ECG loans by the same bank. Further, propensity score matching estimations show that the ex-post performance of firms that received ECG loans from the main bank deteriorated more than that of firms that received non-ECG loans. We do not find such loan “substitution” or performance “deterioration” effects when a non-main bank extended ECG loans. Our findings suggest that close firm–bank relationships may have perverse effects on the efficacy of public credit guarantees.     

Optimal credit limit management under different information regimes

Credit limit management is of paramount importance for successful short-term credit risk management, even more so when the situation in credit and financial markets is tense. We consider a continuous-time model where the credit provider and the credit taker interact within a game-theoretic framework under different information structures. The model with complete information provides decision-theoretic insights into the problem of optimal limit policies and motivates more complicated information structures. Moving to a partial information setup, incentive distortions emerge that are not in the bank’s interest. We discuss how these distortions can effectively be reduced by an incentive-compatible contract. Finally, we provide some practical implications of our theoretical results.     

Why is credit-to-GDP a good measure for setting countercyclical capital buffers?

We examine banks’ loan losses in Europe in 1982–2012 using a nonlinear three-factor model that takes into account output growth, real interest rate, and the ratio of private credit to GDP relative to its trend (i.e., “excessive indebtedness”). We find that a drop in output has an intensified impact on loan losses if the private sector is excessively indebted. Because increased bank credit risk should be matched with higher bank capital, the result motivates the Basel III's countercyclical capital buffers as a function of private indebtedness relative to its trend. The result also helps to explain differences in the amount of loan losses in different recessions across time and across countries. The model also indicates that low interest rates during the recent recession have clearly mitigated loan losses.     

Customers and investors: A framework for understanding the evolution of financial institutions

Financial institutions are financed by both investors and customers. Investors expect an appropriate risk-adjusted return for providing financing and risk bearing. Customers, in contrast, provide financing in exchange for specific services, and want the service fulfillment to be free of the intermediary's credit risk. We develop a framework that defines the roles of customers and investors in intermediaries, and use it to build an economic theory that has the following main findings. First, with positive net social surplus in the intermediary-customer relationship, the efficient (first best) contract completely insulates the customer from the intermediary's credit risk, thereby exposing the customer only to the risk inherent in the contract terms. Second, when intermediaries face financing frictions, the second-best contract may expose the customer to some intermediary credit risk, generating “customer contract fulfillment” costs. Third, the efficiency loss associated with these costs in the second best rationalizes government guarantees like deposit insurance even when there is no threat of bank runs. We further discuss the implications of this customer-investor nexus for numerous issues related to the design of contracts between financial intermediaries and their customers, the sharing of risks between them, ex ante efficient institutional design, regulatory practices, and the evolving boundaries between banks and financial markets.     

Pricing of payment cards, competition, and efficiency: a possible guide for SEPA

This paper analyzes equilibrium pricing of payment cards and welfare consequences of payment card competition. In particular, we model competition between debit and credit cards. The paper argues that optimal consumer and merchant fees must take safety, income uncertainty, default risk, and the merchant’s handling cost of cash into account. Market segmentation where debit and credit cards serve different merchant segments yields a preferred “payment mix”. However, when markets are segmented, payment card fees do not necessarily reach their socially efficient levels. Hence, thoughtful regulatory intervention regarding merchant fees may still be necessary to raise total surplus.     

Dynamic CEO Compensation

We study optimal compensation in a dynamic framework where the CEO consumes in multiple periods, can undo the contract by privately saving, and can temporarily inflate earnings. We obtain a simple closed‐form contract that yields clear predictions for how the level and performance sensitivity of pay vary over time and across firms. The contract can be implemented by escrowing the CEO's pay into a “Dynamic Incentive Account” that comprises cash and the firm's equity. The account features state‐dependent rebalancing to ensure its equity proportion is always sufficient to induce effort, and time‐dependent vesting to deter short‐termism.     

Deposit interest rate ceilings as credit supply shifters: Bank level evidence on the effects of Regulation Q

How did deposit interest rate ceilings, an important feature of the U.S. regulatory regime until the mid-1980s, affect individual banks’ lending and the transmission of monetary policy to credit? I estimate the effect of deposit rate ceilings inscribed in Regulation Q on commercial banks’ credit growth using a historical bank level data set starting in 1959. Banks’ credit growth contracted sharply when legally fixed deposit rate ceilings were binding. Interaction terms with monetary policy suggest that the policy impact on bank level credit growth was non-linear and significantly larger when rate ceilings were in place. Bank size and capitalization mitigate these effects. At the bank level, short-term interest rates exceeding the legally fixed deposit rate ceilings identify policy induced credit supply shifts that disappeared with deposit rate deregulation and thus weakened the bank lending channel substantially since the early 1980s.     

Capital controls and monetary policy autonomy in a small open economy

Is there a link between capital controls and monetary policy autonomy in a country with a floating currency? Shocks to capital flows into a small open economy lead to volatility in asset prices and credit supply. To lessen the impact of capital flows on financial instability, a central bank finds it optimal to use the domestic interest rate to “manage” the capital account. Capital account restrictions affect the behavior of optimal monetary policy following shocks to the foreign interest rate. Capital controls allow optimal monetary policy to focus less on the foreign interest rate and more on domestic variables.     

Bank interest rates and credit relationships in Italy

When evaluating the performance of a financial system in supporting the investment activity of the corporate sector, a distinction is usually drawn between “banking economies” and “market economies”, the former being characterized by long-term relations between banks and the industrial sector. Although theoretical studies and empirical results seem to agree that lending relationships increase the available quantity of capital to firms, they have little to say on the cost of bank credit: it is not clear whether a close relationship with a main bank would allow the borrower to pay a lower interest rate or expose him to a monopolistic rent. Using a unique data-set reporting detailed information on the evolution over time of individual bank–borrower relationships in Italy, we show evidence that a main bank provides credit at a lower cost and that some competition helps to reinforce the commitment between the borrower and the bank.     

银行竞争背景下定向降准政策的“普惠”效应——基于A股和新三板三农、小微企业数据的分析

本文基于A股和新三板企业的微观数据,采用倍差法(DID)检验定向降准货币政策的实施是否对农业和小微企业等所谓“弱势部门”的信贷资源产生了作用,从而实现政策的“普惠”效应。同时基于定向降准政策的影响机制,本文将基于时间维度和区域维度的银行竞争引入实证模型,进一步探讨了银行竞争对定向降准政策“普惠”效应的影响。结果表明:首先,我国定向降准政策可以促进农业企业和小微企业获取信贷资源,发挥了普惠效应;其次,银行竞争可以在一定程度上对定向降准政策的“普惠”效应表现出正向调节作用,具体来说,时间维度的银行竞争对定向降准政策的“普惠”效应的影响较为明显,区域维度的银行竞争没有调节作用。     

比较法视域下公司董事赔偿责任保险立法问题研究——基于日本第二次《公司法》修改的比较考察

D&O保险的立法问题是我国司法实践中一个亟需澄清的问题,同时亦是保险法学界关注较多的基础理论问题。本文通过考察D&O保险合同在公司治理中的价值,细致分析在2019年日本第二次《公司法》修改之际学界对D&O保险规则立法与否的争论及立法演进历程,并对增设D&O保险合同规定的初衷以及在决定该保险合同内容时的决策程序进行系统阐释。研究发现,增设D&O保险合同规定、明确公司有权全额负担保险费用,有助于提高管理层的风险承担水平和管理效率,进而促进企业创新。在探讨我国《公司法》是否应当构建D&O保险规则这一问题时,应注意到公司法上的补偿制度是D&O保险存在的前提。就D&O保险合同内容的信息披露问题,一方面,为防止公司费用无限地用于提升填补限额,可采披露D&O合同信息的手段;另一方面,就具体的信息披露事项,不可盲目“照搬”美国做法。     

Breaking up big banks

This paper discusses the proposals to limit the size of the banks, also known as tackling the banks’ incentives to become “too big to fail”. I examine how regulations to curb bank size may affect banks’ operating costs. I analyze the relationship between the size of U.S. bank holding companies (BHCs) and their operating costs from 2001:Q2 to 2014:Q1. I find that rules to limit the size of banks could significantly reduce economies of scale. In particular, if large and cost-efficient banks become split into smaller parts, data processing, legal fees, audit and consulting expenses, expenses on premises are likely to increase.The second part of the paper deals with the phenomenon known as “too big to jail” and examines banks’ settlements. I compile a novel dataset on 341 litigation charges and settlements and find evidence that larger banks and banks with a higher credit risk, but not necessarily more systemically risky banks, face litigation charges more frequently. I do however observe that penalties had little effect on BHCs’ profitability, and that some of the largest banks continuously faced litigation charges which may imply that benefits from wrongdoing outweighed the costs or that many large banks relied on the fact they will be considered immune from prosecution due to their sheer size and their influence on the economy.     

Cash burns: An inventory model with a cash-credit choice

A dynamic cash-management model is analysed where agents choose whether to pay with cash or credit at every point in time. In the model credit usage depends on the current stock of cash, a novel result that matches recent micro evidence on households’ payment choices. The optimality of such a decision rule is novel and cannot be obtained by models where cash-credit decisions are made at the “beginning” of each period. We discuss how to use the model to account for cross country-evidence on the intensity of credit usage and for several statistics on the size and frequency of cash withdrawals. The model is used to assess the household’s welfare cost of phasing out cash.     

The ties that bind: Bank relationships and small business lending

The importance of bank relationships for small firms’ ability to raise external finance is well-documented, yet the mechanism through which relationships improve access to capital markets has received little empirical attention. This paper uses hand-collected, proprietary data from a mid-sized bank in the United States to identify the channels that strengthen the relationship between a small business and its bank. In contrast to earlier work that focuses on the role of relationships in alleviating information and incentive problems in lending, I find that the source of value in relationship banking is not limited to enhanced monitoring. Exploiting a unique feature of this dataset, I examine two channels of relationship strength that directly measure the stream of non-lending profits generated from (1) the non-credit services cross-sold to the borrower, and (2) the additional bank clients referred by the borrower. I document that non-lending profitability empirically determines the risk-adjusted terms of lending. In models of loan price that already include both the bank’s proprietary risk rating and traditional risk proxies, non-lending profits significantly improve explanatory power and account for up to half of the total explained variation. Conditional on risk profile, a one-standard deviation increase in aggregate non-lending profits lowers the loan interest rate by 32 basis points and increases access to credit by 26%.     

Optimal Forbearance of Bank Resolution

This paper analyzes a regulator's optimal strategic delay of resolving banks when the regulator's announcement of the intervention delay endogenously affects the depositors' run propensity. Given intervention, the regulator either liquidates the remaining illiquid assets (“prompt corrective action”) or continues managing the assets at a reduced skill level (“resolution under receivership”). In either case, I show that if the regulator tolerates fewer withdrawals until intervention, the depositors may react by preempting the regulator: they run on the bank more often ex ante. A policy of never intervening can leave the bank more stable than a conservative intervention policy.     

Resaleable debt and systemic risk

Many debt claims, such as bonds, are resaleable; others, such as repos, are not. There was a fivefold increase in repo borrowing before the 2008–2009 financial crisis. Why? Did banks’ dependence on non-resaleable debt precipitate the crisis? In this paper, we develop a model of bank lending with credit frictions. The key feature of the model is that debt claims are heterogenous in their resaleability. We find that decreasing credit market frictions leads to an increase in borrowing via non-resaleable debt. Such borrowing has a dark side: It causes credit chains to form, because, if a bank makes a loan via non-resaleable debt and needs liquidity, it cannot sell the loan but must borrow via a new contract. These credit chains are a source of systemic risk, as one bank’s default harms not only its creditors but also its creditors’ creditors. Overall, our model suggests that reducing credit market frictions may have an adverse effect on the financial system and even lead to the failures of financial institutions.     

Bank Lending Standards and Access to Lines of Credit

This paper examines how changes in bank lending standards are related to the availability of bank lines of credit for private and comparable public firms. Overall, we find that access to lines of credit is more contingent on bank lending standards for private than for public firms. The impact of bank lending standards is however asymmetric: while private firms are less likely than public firms to gain access to new lines when credit market conditions are tight, we find no difference between public and private firms in terms of their use or retention of pre‐existing lines. We also find that private firms without lines of credit use more trade credit when bank lending standards are tight, which is suggestive of a supply effect. Overall, the evidence suggests that “credit crunches” are likely to have a disproportionate impact on private firms. However, pre‐existing banking relationships appear to mitigate the impact of these contractions on private firms.
