Liquidity Coinsurance, Moral Hazard, and Financial Contagion

We study the propagation of financial crises among regions in which banks are protected by limited liability and may take excessive risk. The regions are affected by negatively correlated liquidity shocks, so liquidity coinsurance is Pareto improving. The moral hazard problem can be solved if banks are sufficiently capitalized. Under autarky a limited amount of capital is sufficient to prevent risk‐taking, but when financial markets are open capital becomes insufficient. Thus, bankruptcy occurs with positive probability and the crisis spreads to other regions via financial linkages. Opening financial markets is nevertheless Pareto improving; consumers benefit from liquidity coinsurance, although they pay the cost of excessive risk‐taking.

Asset Liquidity,Moral Hazard,and Bank Loan Rescheduling

We analyze the bank's decision to reschedule or to foreclose on a loan in default and the borrower's decision to divert lender-financed assets to personal use, i.e., to consume the assets. We show that the debt of borrowers in financial distress that have substantial intangible or highly specialized assets—i.e., illiquid assets—is likely to be rescheduled. Alternatively, banks will likely foreclose on borrowers in distress that have assets that are difficult to monitor. It is the interaction of the asset's liquidity and the borrower moral hazard that helps determine the nature of the equilibrium. When the condition of the borrower upon default is observable, we find that suboptimal foreclosures are possible but reschedulings are always optimal; when the borrower's condition is private information, however, reschedulings may also be suboptimal. Additionally, borrowers whose lenders foreclose are more impaired then those whose debt is rescheduled. Finally, we show that randomization of the rescheduling/foreclosure decision by the bank and the decision to consume by the borrower may be optimal for particular assets.     

Trader Leverage and Liquidity

Does trader leverage drive equity market liquidity? We use the unique features of the margin trading system in India to identify a causal relationship between traders’ ability to borrow and a stock's market liquidity. To quantify the impact of trader leverage, we employ a regression discontinuity design that exploits threshold rules that determine a stock's margin trading eligibility. We find that liquidity is higher when stocks become eligible for margin trading and that this liquidity enhancement is driven by margin traders’ contrarian strategies. Consistent with downward liquidity spirals due to deleveraging, we also find that this effect reverses during crises.     

流动性、杠杆率与金融稳定

本文主要研究流动性和杠杆率之间交互作用的机理及其对金融稳定的影响.文章认为,随着金融结构的演变,流动性的内涵不断扩大,金融机构以证券化的方式实现流动性的扩张.金融机构的杠杆率具有明显的顺周期特征,容易放大金融周期的波动;并且由于杠杆率与流动性变化之间交互作用,导致社会总体流动性在短期内出现逆转,造成金融体系的不稳定.因此,政策制定者应该加强杠杆率和流动性管理,建立维护金融稳定的政策框架体系.     

Deposit Insurance, Moral Hazard and Market Monitoring

The paper analyses the relationship between deposit insurance, debt-holder monitoring, and risk taking. In a stylised banking model we show that deposit insurance may reduce moral hazard, if deposit insurance credibly leaves out non-deposit creditors. Testing the model using EU bank level data yields evidence consistent with the model, suggesting that explicit deposit insurance may serve as a commitment device to limit the safety net and permit monitoring by uninsured subordinated debt holders. We further find that credible limits to the safety net reduce risk taking of smaller banks with low charter values and sizeable subordinated debt shares only. However, we also find that the introduction of explicit deposit insurance tends to increase the share of insured deposits in banks' liabilities.

Adverse Selection, Moral Hazard, and Outlier Payment Policy

In this article, we analyze the rationale for introducing outlier payments into a prospective payment system for hospitals under adverse selection and moral hazard. The payer has only two instruments: a fixed price for patients whose treatment cost is below a threshold     and a cost-sharing rule for outlier patients. We show that a fixed-price policy is optimal when the hospital is sufficiently benevolent. When the hospital is weakly benevolent, a mixed policy solving a trade-off between rent extraction, efficiency, and dumping deterrence must be preferred. We show how the optimal combination of fixed price and partially cost-based payment depends on the degree of benevolence of the hospital, the social cost of public funds, and the distribution of patients severity.     

道德风险与金融危机

不可否认,当前的金融危机给政策的面貌带来了翻天覆地的冲击.在一个接一个的国家里,我们看到政府恐慌地做出膝跳反射似的反应,并把他们的政策手册扔到一边:前所未有的救助和国有化开始出现,审慎的财政政策灰飞烟灭,毫无保留的凯恩斯主义已经回归.很多人宣称,我们尝试的自由市场已经失败,现在应该进行更广泛的监管和更积极的宏观经济管理.

Moral Hazard, Effort Sensitivity and Compensation in Asset-Backed Securitization

One interesting explanation for asset securitization is the managerial agency theory—where securitization of cash flows that are relatively insensitive to managerial effort reduces the noise for cash flows that are sensitive to managerial effort (Iacobucci and Winter, 2005). This paper extends this concept in several ways. First, we differentiate the effects of noise and effort sensitivity on managerial effort and compensation, underscoring the importance of a less noisy environment. We also carefully delineate the conditions under which asset securitization would improve the welfare of managers and shareholders of the originating company. Second, we relax the assumptions regarding the expected income-producing function and the income variance, and further take into consideration the change of the marginal production of income with respect to effort before and after securitization. Third, under a multitask principal-agent model framework, we explore how the relationship between managerial activities on different assets affects the incentive compensation for the manager of the originating company and the joint surplus for shareholder and manager. This is particularly relevant when entire buildings are securitized as opposed to pools of income-generating assets. Finally, we examine the role of the third-party servicer.

Skin in the Game and Moral Hazard

What determines securitization levels, and should they be regulated? To address these questions we develop a model where originators can exert unobservable effort to increase expected asset quality, subsequently having private information regarding quality when selling ABS to rational investors. Absent regulation, originators may signal positive information via junior retentions or commonly adopt low retentions if funding value and price informativeness are high. Effort incentives are below first‐best absent regulation. Optimal regulation promoting originator effort entails a menu of junior retentions or one junior retention with size decreasing in price informativeness. Zero retentions and opacity are optimal among regulations inducing zero effort.     

Deposit Insurance and Forbearance Under Moral Hazard

We study the efficacy of forbearance using a real options approach. Our model endogenizes moral hazard embedded in credit risk undertaken by the bank. The bank's interest rate risk is modeled as duration mismatch. Other modeling improvements over previous studies include such features as stochastic interest rates and deposits, continuous interest payments on an ongoing deposit portfolio, and a stochastic forbearance period. We find that the bank does have an incentive to engage in undue risk taking. Even in the presence of moral hazard, however, forbearance can still be a desirable course of action in reducing the FDIC's expected liability. In addition, the capital ratio plays an extremely important role in determining the fair insurance premium. Finally, using the mismatch of asset and deposit durations as the correct measurement of interest rate risk, our model reveals that an optimal asset variance may exist for a particular bank, contrary to what the contingent claims framework would predict. Therefore, we resolve the puzzle that banks in practice do not increase asset risk to take full advantage of the limited liability.

Moral Hazard in Lending and Labor Market Volatility

When the economy experiences a sharp economic downturn, credit spreads widen and project financing costs for firms rise as funding sources begin to dry up. The economy experiences a lengthy recovery, with unemployment rates slow to return to “full employment” levels. We develop a model that displays these features. It relies on an interaction between labor search frictions and firm‐level moral hazard that is accentuated during recessions. The model is capable of addressing the “Shimer puzzle,” with labor market variables exhibiting significantly more volatility on average as a result of the heightened moral hazard concerns during these episodes that significantly deepen and prolong periods of high unemployment, as vacancy postings fall dramatically and the job‐finding rate declines. Our mechanism is also found to induce internal shock propagation causing the peak response of output, unemployment, and wages to occur with a several quarter delay relative to a model without such frictions. Many other labor market variables also show slower recovery—their return to preshock level occurs at a slower pace for a number of periods after the peak response.     

Leases with Purchase Options and Double Moral Hazard

Abstract:  The purpose of this paper is to explain why leases have a purchase option and how the exercise price of this option is determined. We follow Demski and Sappington's (1991) approach by using a double moral hazard setting. One limitation of their model is that the agent has unlimited liability. The agent has to have enough wealth and the obligation to buy the firm when the principal decides to exercise the put option. In our paper, this problem is resolved by using a call option, which is a feature of many lease contracts. We show that leases with a purchase option can completely resolve the double moral hazard problem even if all the variables in the model are unverifiable. It is the threat of being the residual claimant that induces the lessor to provide an efficient level of effort. On the other hand, it is the opportunity of being the residual claimant that induces the lessee to maintain the asset efficiently. Finally, the model predicts that certain leased assets are not properly accounted for under the current accounting standards for leasing.
