The Distributive Impact of Reforms in Credit Enforcement: Evidence From Indian Debt Recovery Tribunals

It is generally presumed that stronger legal enforcement of lender rights increases credit access for all borrowers because it expands the set of incentive compatible loan contracts. This result relies on an assumption that the supply of credit is infinitely elastic. In contrast, with inelastic supply, stronger enforcement generates general equilibrium effects that may reduce credit access for small borrowers and expand it for wealthy borrowers. In a firm‐level panel, we find evidence that an Indian judicial reform that increased banks' ability to recover nonperforming loans had such an adverse distributive impact.     

相关性下的银行风险集成研究综述

银行风险之间的相关关系会使风险之间相互转化,相互影响,令风险呈现出放大或者缩小的趋势,显著影响着银行风险度量结果的准确性。银行风险集成致力于在充分考虑银行风险相关关系的基础上,对银行风险进行较为准确的度量。但是银行风险具有相关关系种类繁多、表现形式复杂、以及数据的可获得性差等显著特征,导致银行风险的集成度量领域存在诸多挑战。本文对相关性下的银行风险集成研究进行综述,具体从集成对象、集成方法和集成数据三个层次系统展开。首先对银行风险及其蕴含的种类繁多的相关关系类型进行解析,然后分析银行风险相关关系表征出的多种复杂特性,根据对这些特性的刻画能力对银行风险的集成方法进行划分和比较,最后总结了获取银行风险集成数据的多种途径。在此基础上,进一步分析了银行风险集成研究的难点和未来趋势。     

Old Structures,New Relations: How Community Development Credit Unions Define Organizational Boundaries

Studies of organizational dynamics examine the manner in which an organization's immediate environment defines the rules and requirements to which individual organizations must conform in order to receive legitimacy and support (Scott, 1992:132). In this paper we consider the question of how an organization can achieve legitimacy and support without necessarily compromising its organizational forms or practices to isomorphic pressures. We frame the question in terms of the boundaries between organizations and their environments. Where the population ecology studies show the survival value of adopting known organizational forms and practices, and neoinstitutionalism addresses the need to display compliance with accepted forms, our case study demonstrates the possibility of removing an organization or set of organizations from the familiar interaction by naming it as a subfield of the organizational field, sharing the environment, but out of the way of predefined norms and practices.     

Hidden Consumer Loans: An Analysis of Implicit Interest Rates on Bounced Checks

Payday lending attracts attention for its high interest rates, but bounce protection loans are much more expensive. Bounce protection is a program where consumers overdraft—write checks in excess of the checking account balance—and the bank pays the check allowing the account balance to be negative. For this service/loan, banks charge the standard non-sufficient funds (NSF) fee. When the amount borrowed is low and the time outstanding is short, the effective interest rate paid on this loan can be quite high. Using a unique data set we were able to quantify how high the interest rate is. We found that the median implicit interest paid by consumers is over 4,000%.

The impact of health insurance cost-sharing method on healthcare utilisation in China

In current Chinese health insurance programmes, there are two types of cost-sharing methods: the time-of-service copayment policy and the reimbursement policy. In contrast to the copayment participants, reimbursement participants need to pay for all medical expenses in advance. We study the effect of the reimbursement policy on the utilisation of healthcare services in China. The theoretical analysis indicates that the medical consumption of low income households will be less than the optimal consumption level when enrolled in a reimbursement programme instead of a copayment programme. Empirically, using data from the China Health and Retirement Longitudinal Study (CHARLS), we find that the total inpatient expenditure of the reimbursement participants is 12.7% lower than that of copayment enrolees, and the reimbursement arrangement negatively impacts low-income and rural populations. Therefore, reimbursement participants, those who are financially constrained, are more likely to suffer the up-front payment burden and finally reduce their healthcare needs.

A Bottom-Up Dynamic Model of Portfolio Credit Risk with Stochastic Intensities and Random Recoveries

In Bielecki et al. (2014a Bielecki , T. R. , Cousin , A. , Crépey , S. , Herbertsson , A. ( 2014a ). Dynamic hedging of portfolio credit risk in a markov copula model . J. Optimiz. Theor. Applic . doi: DOI 10.1007/s10957-013-0318-4 (forthcoming) .[Crossref] , [Google Scholar]), the authors introduced a Markov copula model of portfolio credit risk where pricing and hedging can be done in a sound theoretical and practical way. Further theoretical backgrounds and practical details are developed in Bielecki et al. (2014b Bielecki , T. R. , Cousin , A. , Crépey , S. , Herbertsson , A. ( 2014b ). A bottom-up dynamic model of portfolio credit risk - Part I: Markov copula perspective . In: Recent Adv. Fin. Eng. 2012 , World Scientific (preprint version available at http://dx.doi.org/10.2139/ssrn.1844574) . [Google Scholar],c) where numerical illustrations assumed deterministic intensities and constant recoveries. In the present paper, we show how to incorporate stochastic default intensities and random recoveries in the bottom-up modeling framework of Bielecki et al. (2014a Bielecki , T. R. , Cousin , A. , Crépey , S. , Herbertsson , A. ( 2014a ). Dynamic hedging of portfolio credit risk in a markov copula model . J. Optimiz. Theor. Applic . doi: DOI 10.1007/s10957-013-0318-4 (forthcoming) .[Crossref] , [Google Scholar]) while preserving numerical tractability. These two features are of primary importance for applications like CVA computations on credit derivatives (Assefa et al., 2011 Assefa , S. , Bielecki , T. R. , Crépey , S. , Jeanblanc , M. ( 2011 ). CVA computation for counterparty risk assessment in credit portfolios . In: Bielecki , T.R. , Brigo , D. , Patras , F. , Eds., Credit Risk Frontiers . Hoboken : Wiley/Bloomberg-Press . [Google Scholar]; Bielecki et al., 2012 Bielecki , T. R. , Crépey , S. , Jeanblanc , M. , Zargari , B. ( 2012 ). Valuation and Hedging of CDS counterparty exposure in a markov copula model . Int. J. Theoret. Appl. Fin. 15 ( 1 ): 1250004 .[Crossref] , [Google Scholar]), as CVA is sensitive to the stochastic nature of credit spreads and random recoveries allow to achieve satisfactory calibration even for “badly behaved” data sets. This article is thus a complement to Bielecki et al. (2014a Bielecki , T. R. , Cousin , A. , Crépey , S. , Herbertsson , A. ( 2014a ). Dynamic hedging of portfolio credit risk in a markov copula model . J. Optimiz. Theor. Applic . doi: DOI 10.1007/s10957-013-0318-4 (forthcoming) .[Crossref] , [Google Scholar]), Bielecki et al.

基于EOQ模型的存货质押融资业务模式选择研究

委托监管模式、物流银行模式和统一授信融资模式是存货质押融资的几种主要模式,本文采用EOQ模型研究了这三种融资模式下供应链成员的决策和收益情况,并分析了这三种融资模式中制造商与物流企业参与融资的条件。通过对融资模式进行比较分析,论文指出了融资模式对供应链成员收益的影响。主要研究结论指出,在质押率和融资利率的特定区域内,物流企业和制造商同时愿意参与质押融资。由于在统一授信模式中,银行的日常的运营成本比委托监管模式低,银行获得比委托监管模式更多的利润。在选择融资模式时,银行更偏好于统一授信模式。对于物流企业来说,若统一授信模式中物流企业的沉淀资金收益率大于银行的利率,它的利润要比委托监管模式更多,否则要少于委托监管模式。本文的研究结论为存货质押融资业务的模式选择提供了一些的理论参考。
