保障性住房政策的选择运用

本文从住房保障政策的市场效应、补贴效用、对城市规划的影响以及各国的运用启示等角度分析了供给方补贴和需求方补贴的优缺点。并指出在当前我国城市化处于快速发展,房地产价格持续攀升的背景下应优先采用供给方补贴的住房保障政策,但随着我国经济过热形势的好转,住房供不应求态势有所转变,适当考虑需求方补贴的住房保障政策可以提高补贴效率,并适应我国低收入阶层庞大的现实。     

The short of it: Investor sentiment and anomalies

This study explores the role of investor sentiment in a broad set of anomalies in cross-sectional stock returns. We consider a setting in which the presence of market-wide sentiment is combined with the argument that overpricing should be more prevalent than underpricing, due to short-sale impediments. Long-short strategies that exploit the anomalies exhibit profits consistent with this setting. First, each anomaly is stronger (its long-short strategy is more profitable) following high levels of sentiment. Second, the short leg of each strategy is more profitable following high sentiment. Finally, sentiment exhibits no relation to returns on the long legs of the strategies.     

Evidence of Information Asymmetries in the Market for Residential Condominiums

Previous research (Rutherford et al. 2005; Levitt and Syverson 2005) identify and quantify agency problems in the brokerage of single-family houses. Real estate agents are found to receive a premium when selling their own houses in comparison to similar client-owned houses. Given the homogeneity of the condominium market in comparison to the single-family house market, we use a large sample of condominium transactions to examine if agency problems exist in the condominium market. Controlling for sample selection and endogeneity bias of the data, we find evidence for a similar price premium for agent-owned condominiums. In contrast to the results for single-family houses in the same geographic market, we find that agent-owned condominiums must stay on the market longer to receive a higher price.

Price and earnings momentum in Australian stock returns

There is no prior published Australian research on earnings momentum and only one prior unpublished work of limited depth and scope. We provide some of the first Australian evidence on earnings momentum and revisit price momentum with the first Australian evidence of the behaviour of returns beyond 12 months. Price momentum is found to be a feature of this market, but there is some reversal of returns during the second year after portfolio formation, suggesting trend chasing behaviour. Earnings momentum is also present, but with weak continuation into the second year. Price momentum and earnings momentum are shown to provide independent explanatory power over future returns.     

Stock Market Anomalies: What Can We Learn from Repurchases and Insider Trading?

We examine whether managers’ trading decisions (both at a firm and personal level) are correlated with trading strategies suggested by the operating accruals and the post-earnings announcement drift (SUE) anomalies. We discuss advantages and disadvantages of the use of managerial trading activity to infer managers’ private valuation about their own securities. Our results provide corroborative evidence for the accruals anomaly, i.e., managers’ repurchase and insider trading behavior varies consistently with the information underlying the operating accruals trading strategy. On the other hand, we do not find corroborative evidence for the SUE anomaly.

壳溢价:错误定价还是管制风险？

IPO审核制下,上市公司凭借稀缺的上市资源获得真实价值以外的壳价值。本文检验了上市公司壳价值含量(ESV/MV)与股票横截面收益的关系。在控制了规模、账面市值比、盈利、投资等特征后,我们发现壳价值含量与股票回报率显著正相关。根据ESV/MV构造的对冲组合在时间序列上存在无法被现有风险因子模型所解释的超额收益(壳溢价)。进一步检验表明,壳溢价来源于与管制政策相关的系统性风险而不是股票市场的错误定价。     

The Interaction between Mortgage Financing and Housing Prices in Greece

Although the close empirical relationship between the evolution of mortgage lending and housing prices is well established in the literature, the direction of causation is less clear from a theoretical standpoint. We apply multivariate cointegration techniques in order to address this issue empirically for the Greek economy. Our results, based on a cointegration relationship that we identify as a mortgage loan demand equation, indicate that housing prices do not adjust to disequilibria in the market for housing loans. This suggests that in the long run the causation does not run from mortgage lending to housing prices. In the short run we find evidence of a contemporaneous bi-directional dependence.

Stock selection using a multi-factor model - empirical evidence from the French stock market

Using a Barra-type factor model, we have attempted to determine whether it is possible to beat the benchmark by taking advantage of anomalies established in the financial empirical literature. More specifically we have built an equity premium model based on three sets of factors (accounting variables, stock market characteristics and sector indicators) using a Bayesian method corrected for heteroscedasticity to estimate risk premiums, a technique that takes agents' learning into account. The results are encouraging: first, the factors that carried most weight on the equity premiums corroborated the results of empirical studies described in the financial literature, secondly, the portfolios constructed from our methodology and simulated outside our sample, returned higher performance than the benchmark and rewarded the supplement of volatility.

深交所收盘集合竞价制度的实施效果研究

作为交易制度创新的收盘集合竞价制度于2006年7月在深交所主板实施,本文应用事件研究的方法和EGARCH模型,对沪深股价指数及个股在收盘集合竞价制度实施前后的相对成交量和波动性特征进行比较研究,考察该制度的实施对市场微观结构的影响,结果认为收盘集合竞价的实施基本达到预期政策目标。     

Not all call auctions are created equal: evidence from Hong Kong

On 25 March 2002, the Hong Kong Exchanges and Clearing Ltd (HKEx) introduced an opening call auction. This trading mechanism is designed to facilitate price discovery in the presence of asymmetric information at the market open, increasing opening price efficiency. The design of the HKEx differs significantly from opening auctions in other markets. Contrary to previous research, the results indicate a decrease in market quality following the introduction of the opening call auction. This decline is largest in the less actively traded stocks.

住房价格、房屋购买与中国家庭杠杆率

本文基于中国家庭追踪调查的微观数据以及相匹配的城市层面的住房价格数据,从住房购买需求的角度,给出了一个近年来家庭杠杆率急剧上升的解释。利用中国家庭追踪调查的微观数据探讨了房价上涨对家庭杠杆率的作用机制以及潜在影响。结果表明,住房价格的快速上涨推动了家庭杠杆率的急剧攀升,从数量上看,房价每上涨1倍,样本期间的家庭贷款数额将会增长288. 1%,家庭杠杆率将上升39. 2%,而此部分贷款的增加主要来源于银行贷款而非私人借贷,由房价导致的家庭借贷数额和杠杆率的上升大概占到购房家庭总体借贷数额和杠杆率上升的90%左右。机制分析表明,住房价格的快速上涨刺激了家庭必需型和投资型住房需求,并提高了家庭的借贷意愿和风险偏好。分样本的探讨发现,这一效应对于非农户口家户以及有配偶和子女家户的影响更为明显。     

收入差异下的住房财富效应分化——基于283个地级市数据和CHFS家庭微观数据的实证分析

本文将收入分配结构因素纳入LC-PIH模型,试图从收入分层角度寻找我国住房市场弱财富效应的根源。基于283个地级市的面板数据和CHFS家庭微观调查数据的实证研究表明:房价对消费的影响具有门限特征,中等收入城市的住房财富效应最为明显;收入作用下的家庭住房财富效应也呈现倒U形。总体上,我国住房财富效应较弱源于收入的结构性差异,中等收入群体比重偏低可能导致房价上涨对消费的促进作用被低收入阶层和高收入阶层的挤出作用抵消。     

资源性资产市场化定价机制的构建与完善

资源性资产的稀缺性和对经济社会发展的重大意义,要求改革当前的行政定价模式并构建市场化定价机制,以形成有效价格信号.需要强调,构建资源性资产的市场化定价机制,绝不只是由行政主导向市场主导的单轨式推进,它是一项系统性工程,不可能一蹴而就.具体而言,构建资源性资产的市场化定价机制,要求着眼于价格体系重构和竞价流程优化改进.在价格体系重构方面,要实行”完全成本”定价方式,把资源性资产的原生态价值、劳动消耗价值和生态补偿价值充分凸显出来.在竞价流程优化改进方面,既要完善竞价环节,落实以资产评价价值为基础并充分实现生态补偿的公平竞价机制;还要强调竞价方式的差别化和适用性,根据不同竞价环境、不同竞价对象,选     

Have capital market anomalies attenuated in the recent era of high liquidity and trading activity?

We examine whether the recent regime of increased liquidity and trading activity is associated with attenuation of prominent equity return anomalies due to increased arbitrage. We find that the majority of the anomalies have attenuated and the average returns from a portfolio strategy based on prominent anomalies have approximately halved after decimalization. We provide evidence that hedge fund assets under management, short interest and aggregate share turnover have led to the decline in anomaly-based trading strategy profits in recent years. Overall, our work indicates that policies to stimulate liquidity and ameliorate trading costs improve capital market efficiency.
