泡沫经济破灭前后日本银企信用风险管理制度及其功效分析

战后,日本金融体系效仿欧美国家建立起一系列信用风险管理制度。同时,根据市场主导型金融市场的特点,逐步建立起具有自身特点的信用风险管理制度。日本银企信用风险管理制度包括商业银行的内部控制制度、银行风险防御及挽救制度、商业银行外部监管制度。通过对日本银企信用风险管理制度的功效进行剖析,可以看出这一制度存在局限性并与日本的泡沫经济、金融危机、金融效率存在内在关系。

代理问题中的长期关系型契约——解决国有企业委托代理问题的新思考

现代企业的委托代理问题是目前我国国有企业面临的一个现实而棘手的问题,有大量相关文献论及国有企业的委托代理问题及其解决对策,但都忽视了我国国情的特殊性。本文提出了“长期全方位关系型契约”概念,试图从契约的设计、激励约束机制的长期契约安排角度,讨论国有企业委托代理问题,指出委托代理问题解决的关键是委托人与代理人长期综合利益的协调一致。

Illiquidity Premium in the MILA

This article analyzes the illiquidity premium in the MILA. Using seven proxies for illiquidity, we find a positive and significant illiquidity premium for our sample. A microstructure bias-free portfolio weighting based on past returns is critical in our finding of an illiquidity premium, which is robust to several methodological changes in our portfolio simulations. We also document that the premium is present only in small and high book-to-market stocks. Nonetheless, when we control for size and distress effects, the difference and significance in risk-adjusted returns between portfolios of high and low illiquidity stocks remains.     

金融创新如何缓解信任品市场失灵?——中国食品安全责任强制保险的自然实验

信任品市场(如食品、医药等)存在的问题一直困扰着中国和世界很多国家。关于产品和服务质量的信息不对称(道德风险和逆向选择)会导致信任品市场失灵。缓解信任品市场失灵,一种常见的解决方案是政府监管;而经济学家认为更加基于市场的解决方案(例如强制责任保险等金融创新)可能更为有效。在理论上,强制责任保险有两种相反的效应:保险公司的监督减少了道德风险 vs. 保险加剧了企业的道德风险,但一直亟待实证检验。幸运的是,中国食品安全责任强制保险的改革实验走在了世界的前列。本文利用了中国在不同地区、不同时间推行的这个自然实验,通过双重差分的方法识别出责任保险对于信任品市场的因果效应。本文的研究发现,强制责任保险能显著降低食品安全事故发生概率。这表明政府强制推行的金融创新可以成为信任品市场失灵的一种有效的替代性解决方案。     

Market structure and rating strategies in credit rating markets – A dynamic model with matching of heterogeneous bond issuers and rating agencies

This paper investigates the impact of rating agencies in a market with asymmetric information. In particular, the role of credit rating agencies as an intermediary between investors and bond issuers is discussed. We model this setting in a dynamic framework in which both rating agencies and bond issuers are of heterogeneous quality. Rating agencies can apply costly research technology to reveal the fundamental nature of bond issuers and engage in rating smoothing. We show that rating smoothing can compensate for low research quality, even though it is accompanied by a quality deterioration in the rating market and market clustering. Moreover, low-quality bond issuers have a general tendency to match with low-quality rating agencies. If investors place a strong emphasis on the reputation of rating agencies, rating markets also tend to be strongly clustered.     

The securitization of gold and its potential impact on gold stocks

We study the market impact of a very successful financial innovation – the SPDR Gold Trust exchange-traded fund (GLD). GLD holds physical gold, and provides traders with a convenient and cost-effective way to gain exposure to gold. We find that after the introduction of GLD, the liquidity of gold company stocks declined, and their adverse-selection risk increased. Over the two-month period after GLD’s introduction, the stocks’ relative effective bid-ask spreads increased by over 15%, while their adverse-selection cost, as measured by the price impact of trades, went up by more than 30%. Gold stocks also experienced significant negative abnormal returns (−12% on average) in the month after GLD started trading. Our findings suggest that GLD attracted traders, especially uninformed traders, away from gold company stocks, and that the resulting negative demand shocks and decrease in the stocks’ liquidity caused their prices to decline. Our results show that existing securities can be seriously adversely affected when a new security enters the market.     

Pitfalls and perils of financial innovation: The use of CDS by corporate bond funds

We use the financial crisis of 2007–2009 as a laboratory to examine the costs and benefits of teams versus single managers in asset management. We find that when a fund uses complex trading strategies involving the use of CDS team-managed funds outperform solo-managed funds. This may be due to the greater diversity of expertise, experience and skill of teams relative to single managers. During the financial crisis, however, the performance premium of teams becomes negative, which may be because of the slower decision times of teams, which are especially costly during times of rapidly changing market conditions.     

On the efficiency of intra-industry information transfers: The dilution of the overreaction anomaly

We revisit the stock market anomaly documented by Thomas and Zhang (2008) and show that the apparent mispricing of information transfers has decayed over time, as the US markets experienced rapid improvements in the efficiency of the underlying price formation processes. Utilizing recent advancements in market microstructure research to estimate firm-specific proxies for market efficiency, we demonstrate that the existence of the overreaction anomaly (where stock prices of late announcers in response to the earnings reported by early announcers in the same industry are negatively related to subsequent price responses of late announcers to their own earnings reports) is specific to an earlier sample period and results from the inefficient incorporation of information into prices, largely attributable to an environment with high barriers to arbitrage. Our results indicate that the pricing efficiency of intra-industry information transfers has increased in the recent years of increased liquidity and markedly higher trading activity.
