信贷市场不完美，产业转型升级和经济增长

本文提出一个信贷市场不完美情况下产业升级的宏观经济模型,其中信用受限的经济主体可以选择不同类型的产业进行投资,产业类型的异质性体现在投资项目的生产效率、投资规模和信用担保程度。经济主体储蓄量的变化会改变信贷在不同生产效率的产业类型之间的分配,而资本在不同产业类型的组合效应造成不同的经济增长模式,包括从事低效产业的落后经济、从事高效产业的先进经济、从事多种产业的混合经济等。     

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.     

论中国金融发展中的结构制约

加入WTO以后中国金融发展面临的主要问题是既要增强国际竞争力,又必须维护国家的金融安全.但目前中国的金融结构存在着严重缺陷,制约了中国金融业的进一步发展与国际竞争力的提升,对金融稳定与安全产生了诸多的不利影响,因此,中国金融发展不能继续依赖数量增长和加快速度的路径,需要转变思路,以结构调整为重点推进中国金融的改革开放与发展,寻求提升国际竞争力与安全性相统一的金融发展之路.     

市场结构理论分析范式演进研究

通过系统地梳理市场结构理论从SCP框架到厂商策略性行为研究的演变历程,并结合分析经济实践变迁,本文发现,推动市场结构理论分析范式演进的两个主要动因是方法论创新和理论范畴拓展。前者导致了结构主义SCP范式的确立和行为主义的兴起;后者催生了以交易费用为核心概念的新制度主义产业组织理论。展望市场结构理论未来的发展趋势,本文认为,从方法论创新上,博弈论将研究重点转向了企业策略性行为;从范畴拓展上,品牌经济学将开创对消费者行为研究的新领域。     

证券市场监管理论——公共利益论、部门利益论的比较与评述

对经典的监管理论,尤其是对公共利益论、部门利益论与捕获论形成的背景、内涵、优缺点、适用条件进行了完整的比较分析,认为这些理论观点对监管的研究和监管实践有着重要的指导意义,但每一种理论都是对监管的某一方面进行的研究,还没有一种理论能够对证券市场监管的所有问题做出满意的解释。要提高我国证券市场监管的效果,需要从整体上运用这...     

A contrast analysis of online hotel web service purchasers and browsers

Ever since the introduction of Internet technology to general business, websites have played an important role in the business and promotional efforts of hotels. However, the existing tourism and hospitality literature contains only a limited number of articles that examine the perceived importance of the different attributes of a hotel website. This paper reports a study that analyzed the different perceptions of specific hotel website attributes between online purchasers and browsers and between Western and Asian users. The empirical findings reveal a set of attributes that are the most important in developing effective hotel websites. The findings also indicate the necessity of designing English- and Chinese-language hotel websites differently, based on the significant differences in the responses obtained from these two groups of online users.
