Do real estate investors trade on momentum?

Real estate markets are known to be less-than-efficient for many reasons, but what roles short-term trading plays are unclear. Do short-term investors bring additional risk to the market and cause prices to deviate from fundamental values? Based on an extensive dataset of property transactions and a policy shock that substantially raised the cost of short-term trading in Hong Kong, we estimate ‘real estate risk’ with and without short-term trading based on return predictability, return volatility, and price dispersion. Our results show that as short-term investors exit the market, market returns are less predictable and less volatile, while prices are less dispersed cross-sectionally. Consistent with herding models in behavioral finance, the findings suggest that short-term investors are momentum traders who do not enhance price efficiency.     

Intraday data and hedging efficiency in interest spread trading

Three government bond futures contracts and their respective 3-month interest rate futures contracts traded on LIFFE are examined. The data period covers three years of observations, January 1994-December 1996, sampled at half-hourly intervals. Borrowing from the calculation of minimum variance hedge ratios, half-hourly minimum variance spread ratios (the ratio of one contract to another, which provides the minimum variance) are estimated for the above contracts. The hypothesis under examination is whether there is any value-added in estimating minimum spread ratios based on intraday data. Three spread ratios are defined: two ratios calculated from daily data and a third one based on intraday data. Evidence tends to indicate that spread ratios calculated from intraday data exhibit a substantially lower variance than the other two spread ratio speciications. Thus, it is shown that intraday data, in comparison with daily data, allow for lower hedging costs. Moreover, the use of intraday-based spread ratios might be a contributing factor to reducing the maximum cumulative loss potentially incurred while holding a spread position.     

连续融资假说与可转换债券赎回条款设计初探——兼析中美与我国台湾赎回条款设计差异及原因

赎回条款是一个重要的可转换债券条款.从公司连续融资的视角看,赎回条款有利于有真实投资期权价值的未来融资.通常具有不久到期的投资期权的公司发行弱赎回保护,并提供短的保护期;具有较晚到期的投资期权的公司发行强赎回保护,且保护期较长.美国发行的可转换债券与此规律相符,中国大陆和台湾地区发行的可转换债券与此规律不相符.中美台可转换债券赎回条款设计的差异,与三地可转换债券融资的相关规定和可转换债券市场的发育程度有关.     

Pricing of off‐balance sheet debt: how do bond market participants use the footnote disclosures on operating leases and postretirement benefit plans?

In this study, we examine whether the public debt market prices information on off‐balance sheet debt arising from operating leases and postretirement plans. We find that bond‐rating agencies price off‐balance sheet debt arising from operating leases and the coefficient on off‐balance sheet debt measure of operating leases is similar to that of capital leases on the balance sheet. Regarding postretirement benefit plans, we find that bond‐rating agencies do price postretirement benefit obligations that are reported in balance sheet but do not price such obligations disclosed in footnotes. We find similar results when we examine corporate bond yields on new debt issues.     

债权人财务分析体系的构建

不同财务分析主体所处环境、所站立场不同,他们的分析目的、分析焦点也应该不同。目前使用的固定指标体系已不能满足不同主体预测、决策的需要。如何解决这个问题?答案是应从不同主体的分析目标出发,确定其各自的分析体系,只有这样才能提高财务分析的效率、效益。本文将从一个侧面,即债权人的角度,谈谈财务分析体系的构建。     

Are there nonlinearities in short‐term interest rates?

The present paper investigates the characteristics of short‐term interest rates in several countries. We examine the importance of nonlinearities in the mean reversion and volatility of short‐term interest rates. We examine various models that allow the conditional mean (drift) and conditional variance (diffusion) to be functions of the current short rate. We find that different markets require different models. In particular, we find evidence of nonlinear mean reversion in some of the countries that we examine, linear mean reversion in others and no mean reversion in some countries. For all countries we examine, there is strong evidence of the need for the volatility of interest rate changes to be highly sensitive to the level of the short‐term interest rate. Out‐of‐sample forecasting performance of one‐factor short rate models is poor, stemming from the inability of the models to accommodate jumps and discontinuities in the time series data.     

意大利国债续发行制度对我国的启示

与国外发达的政府债券市场相比,我国在通过续发行制度提高国债流动性、提高关键期限国债的市场地位、促进国债定价效率方面,还存在明显的不足。本文以意大利国债市场为分析对象,对其相关的续发行制度设计、国债期限安排、理论依据进行分析,指出我国国债市场存在流通期次过多、单期国债流通量过低的问题,并从国库现金管理、交易机制和投资者结构等方面,尝试为未来我国国债续发行制度框架提供有价值的建议。     

我国短期融资券募集资金是否存在短融长投——对中国上市公司的实证研究

本文以发行短期融资券的上市公司为样本,用回归分析的方法实证研究了上市公司短期融资券募集资金的使用情况。实证结果显示短期融资券发行额与营运资金增加额呈显著的负相关关系,与长期资产现金支出、以及偿还债务所支付的现金均呈显著的正相关关系。表明上市公司发行短期融资券募集的资金存在短融长投及集中还贷的现象,也就反映了企业利用市场时机进行融资、并用短期资金进行长期投资的行为。这种短融长投的行为可能因为投融资期限不匹配而导致企业财务风险,并给投资者带来一定的兑付风险。
