基于合同匹配理论的中国农村信贷市场设计

由于农村信贷市场的每笔贷款额度都比较小，银行对借款人的监督成本相对很大，因而难以依靠银行来监督借款人，很容易产生道德风险。结合合同匹配理论的相关结论对中国农村信贷市场做了试探性的设计，设想建立一个集中的信贷匹配结算中心，并提出了一种激励相容的报价支付机制。     

低效信贷市场退出的难点与工作思路

从低效信贷市场退出是我国国有商业银行优化信贷结构、提高信贷资产质量的重要举措之一。就广东的情况看，目前国有商业银行存在着对低效信贷市场退出机制的认识和研究不够、银行考核机制刚性、企业素质低下以及信贷队伍素质不高等诸多问题。本文针对广东国有商业银行从低效信贷市场退出的状况，提出了相应的工作思路。     

信贷市场交易主体的异质性与借贷匹配研究——基于江苏80家商业银行和301家企业的样本数据

本文通过对商业银行和中小微企业的调查,分析信贷市场上不同商业银行和企业之间的匹配关系,研究表明:信贷市场上,不同银行信贷技术、信贷合约的异质性与不同规模企业信息禀赋和融资需求的异质性存在着匹配,但外部环境如信贷基础设施会影响商业银行相关信贷技术的采用,从而使交易主体的借贷匹配有所调整。贷款利率的全面放开进一步促进了商业银行的差异化定位,但该政策是否会提高小微企业的信贷可获性,还取决于信贷基础设施的完善能否促进大银行采用适合小微企业的信贷技术。     

平台竞争一定能提高信息匹配效率吗?——基于中国搜索引擎市场的分析

互联网经济促进了商业模式的变化,各类平台成为生活中不可或缺的部分,但虚假信息、假冒产品等问题也带来了不可忽视的负面影响。本文研究了平台作为供需协调者时的信息策略,揭示了平台在不同竞争条件下控制用户信息的策略动机和相应的结果。研究表明,竞争环境下平台的策略行为会加剧市场中的信息不对称。中国搜索引擎市场的案例证明搜索引擎在技术上实现的信息匹配效率与市场竞争策略存在根本性冲突,搜索引擎对夸张或虚假的广告存在策略性的宽容动机,导致搜索结果出现"劣币现象"。对虚假信息的惩戒、搜索中立原则的倡导是对平台进行监管的关键,也是互联网经济健康发展的制度基础。

Financial Matching, Asymmetric Information and Entrepreneurial Risk Taking

We study financial matching in credit markets when entrepreneurs have private information about their success potential. Entrepreneurs can search for financing for either a “risky” or a “safe” investment and only the risky project is sensitive to entrepreneurs' intrinsic “types”. There is excess risk taking in the sense that entrepreneurs with inefficiently low success probabilities choose the risky investment. However, steady states featuring greater market liquidity are associated with higher efficiency. As market liquidity also reflects the intensity of competition among financiers, earlier results which indicate a negative relationship between competition and allocative efficiency do not hold in our setup.     

Two-sided Markets,Competitive Bottlenecks and Exclusive Contracts

We provide a framework for analyzing two-sided markets that allows for different degrees of product differentiation on each side of the market. When platforms are viewed as homogenous by sellers but heterogeneous by buyers, we show that “competitive bottlenecks” arise endogenously. In equilibrium, platforms do not compete directly for sellers, instead choosing to compete indirectly by subsidizing buyers to join. Sellers are left with none of the gains from trade. Despite this, it is sellers who choose to purchase from multiple platforms (multihome). Finally, the role of exclusive contracts to prevent multihoming is explored. We are very grateful to Jose Miguel Abito for research assistance, and to the editor and a referee for helpful comments.     

Some Empirical Evidence of the Efficacy of Job Matching in Urban Labor Markets

Theory predicts that workers in cities are more likely to engage in job search, ceteris paribus, due to market efficiencies associated with greater job density. However, if job search is more efficient in urban markets, then the quality of a given job match should also tend to be higher in cities, ceteris paribus. Employed workers living in cities might then be expected to search less than their nonurban counterparts. In this latter instance, it is not city residency itself that makes search less likely, but rather the positive correlation between city residency and job match quality. Using data from the National Longitudinal Survey of Youth 1979, this prediction is confirmed: The estimated coefficient on an indicator of urban residency is found to be near zero and statistically insignificant in models of employed search that omit proxies for job match quality. When job match proxies are included in the models, the estimated coefficient on urban residency becomes positive and highly significant. This result suggests that workers are not only more likely to engage in employed search in urban labor markets, but also tend to find more productive job matches in cities over time.

Credit quality, the intensity of regulation and the segmentation of debt markets

Some debt markets have a “competitive advantage” over others due to easier regulatory requirements. Our model explains changes in the market shares of different debt markets. In particular, borrowers may choose between highly regulated and relatively unregulated placement of debt so as to minimize borrowing costs. Borrowers in the highly regulated market incur higher regulatory cost, but are also able to signal accurately their true risk class. In unregulated markets there is an asymmetric information problem. This results in an equilibrium where the debt market is segmented between less regulated and other, more strictly regulated, placements. Raising regulatory costs will lead to an expansion of the market share of unregulated debt. It will also lead to an increase in the overall default rate on corporate debt.     

Matching mechanisms and matching quality: Evidence from a top university in China

We compare competing college admission matching mechanisms that differ in preference submission timing (pre-exam, post-exam but pre-score, or post-score) and in matching procedure (Boston (BOS) and serial dictatorship (SD) matching). Pre-exam submission asks students to submit college preferences before entrance exam scores are known, whereas post-score (post-exam) submission removes (reduces) score uncertainties. Theoretical analyses show that although mechanisms with post-score submission or SD matching are ex-post fair and efficient, they are not so ex-ante. Instead, the mechanism with pre-exam submission and BOS matching can be more fair and efficient ex-ante. These hypotheses are supported by empirical test on data from a top school at a top-ranked Chinese university with identification based on temporal and provincial changes. We find that although students admitted under the pre-exam BOS mechanism have lower college entrance exam scores than students admitted through other mechanisms on average, they exhibit similar or even better college academic performance.

中国商业银行体系信用风险评估——基于宏观压力测试的研究

宏观压力测试,作为压力测试方法在宏观经济分析中的具体运用,可以提供极端事件对金融体系影响的前瞻性信息.随着各国金融监管当局对系统性风险的日趋重视,宏观压力测试方法逐渐成为检验一国银行体系的脆弱性、维护金融稳定的首选工具.本文主要研究宏观压力测试在银行信用风险评估中的应用,并在已有的模型成果的对比分析基础上,建立适用于我国的宏观压力测试模型并以此进行实证分析.本文以贷款违约率作为评估银行系统信用风险的指标,选取对银行信贷违约风险构成冲击的宏观经济变量,通过多元线性回归模型将其整合成为一个综合性指标.研究结果发现:名义国内生产总值(NGDP)和通货膨胀率指标(CPI)对银行体系的贷款表现冲击力较强.在此基础上构建了两种宏观经济极端情境,在关于NGDP大幅下降和CPI骤升的压力情境设定下,银行体系的贷款违约率都出现了不同程度的大幅度提高.尤其在关于通货膨胀率的情境设定下,贷款违约率的增幅高于其在NGDP下降情境下的增幅.     

Truthtelling in Matching Markets

We analyze a search and matching model with non‐transferable utility and asymmetric information. Randomly paired agents go through an evaluation phase, at the end of which they discover each other's types and choose to match or not. Before deciding to enter this phase, agents can communicate through cheap talk. We provide conditions for this communication to be informative, and we examine how it affects agents' welfare. We show that communication is Pareto‐improving only when the matching is assortative in the absence of communication and left unchanged by information transmission.
