对中国人民银行征信法规建设与执法效能的思考

征信法规建设的滞后使得中国人民银行分支机构征信工作缺乏法律依据,一定程度上制约了征信执法效能的发挥。为提高征信执法效能,应进一步完善《征信管理条例》并使之尽早出台,加快制定企业征信方面相关办法、《个人信用信息基础数据库管理办法》实施细则和信用评级方面相关办法等。     

国有商业银行亏损问题研究

由于产权单一、多次降息、资产质量差、无序竞争、财政虚收等十个方面的主客观原因 ,导致了我国国有商业银行严重的经营亏损 ,潜藏着巨大的金融风险 ,但由于有国家信用的强力支撑 ,暂时不会出现金融危机。要解决国有银行亏损问题 ,必须为其创造良好外部环境、进行产权制度改革、发展全能银行和加强金融监管。     

Efficiency comparisons between two estimators based on matrix determinant Kantorovich-type inequalities

We first establish two matrix determinant Kantorovich-type inequalities. Then, based on these two and other inequalities, we introduce new efficiency criteria and present their upper bounds to make efficiency comparisons between the ordinary least squares estimator and the best linear unbiased estimator in the general linear model. We provide numerical examples to examine the upper bounds of some new and old efficiency criteria. Received: June 1999     

Efficiency and productivity change in Ukrainian health care

The study analyses technical efficiency and efficiency change of 193 community hospitals and polyclinics across Ukraine, for the years 1997–2001. These facilities are a subset of the medical institutions in rural Ukraine; they are identical w.r.t. their function in the health system and share the same departmental structure. The data comprise the number of beds in the hospitals, the number of staff employed in the hospitals as well as the polyclinics connected to the hospitals, the number of inpatient and outpatient admissions as well as the number of surgical procedures, lab tests, X-rays performed and the number of deaths and deaths after surgery. Because of the known sensitivity of traditional nonparametric frontier estimators to outlier observations, we employ an order-m estimator, a robust technique, to assess the efficiency of these health care providers as well as changes of their productivity time. The efficiency scores are calculated with an output-oriented model; they are close to unity for hospitals whereas polyclinics seem somewhat less efficient. The Malmquist-indices averaged over all observations are close to unity indicating that productivity does not change over during our observation period. But, depending on the period and the region, substantial deviations from unity can be observed.

基于产业异质性的银行贷款政策效应分析——来自上市银行的经验证据

在银行信贷资金配置存在产业间差异的假定下,建立引入产业因素的银行贷款决定模型,考察产业因素影响银行贷款渠道有效性的内在机制,并运用2007年到2010年14家上市银行和5组产业数据展开动态面板模型估计,结果表明：从贷款需求角度看,各个产业的产出对产业贷款的影响效应存在产业间差异;从贷款供给角度看,人民银行运用货币政策工具调控产业贷款的影响效应也存在产业间差异。也就是说,产业因素确实影响到人民银行调控各个特定产业贷款的力度。     

IPO高抑价之谜：“租金分配观”还是“定价效率观”？——基于2005-2012年数据

对中国IPO极高的抑价现象存在两种不同的解释——“定价效率观”和“租金分配观”。以2005—2012年A股IPO公司作为样本,对这两种观点进行检验,结果表明：“租金分配观”只在2005-2008年成立,在2009-2012年不成立;“定价效率观”则能更好地解释2005年实施询价配售制度以来中国IPO抑价率的变化。     

Connecting National Safety Nets: The Dialectics of the Basel II Contracting Process

Basel II consists of supervisory guidelines negotiated by representatives of central banks and national regulatory commissions that were members of the Basel committee on Banking Supervision (BCBS). The BCBS is itself a regulatory response to globalization, which is connecting national safety nets in market-driven ways. A country’s financial safety net is a social contract established by short-lived agents for principals in long-lived economic sectors. Restraints placed on the authority of the BCBS members to contract for their principals by domestic politics explains: why Basel II authorizes individual countries to implement the agreement in markedly different ways; why US implementation of Basel II ran into so much doubt, controversy, and delay; and how the implementation debate set small and large banks and the Federal Reserve and other federal regulators against one another.

Capital and resolution policies: The US interbank market

We develop an empirically based simulation study to test two types of policies designed to control systemic risk: preventive policies targeting capital requirements and mitigation policies targeting default resolution. We find that capital buffers reduce both the number of defaults and the resulting losses. The loss reduction benefit increases as the magnitude of adverse shocks becomes higher. We find that a simple branch-breakup resolution strategy reduces the loss borne by the Federal Deposit Insurance Corporation (FDIC). The mitigation effect becomes higher as the fraction of assets resolved through auctions and auction competitiveness increase.
