Well-posedness of measurement error models for self-reported data

This paper considers the widely admitted ill-posed inverse problem for measurement error models: estimating the distribution of a latent variable $X^1$ from an observed sample of $X$, a contaminated measurement of $X^1$. We show that the inverse problem is well-posed for self-reporting data under the assumption that the probability of truthful reporting is nonzero, which is supported by empirical evidences. Comparing with ill-posedness, well-posedness generally can be translated into faster rates of convergence for the nonparametric estimators of the latent distribution. Therefore, our optimistic result on well-posedness is of importance in economic applications, and it suggests that researchers should not ignore the point mass at zero in the measurement error distribution when they model measurement errors with self-reported data. We also analyze the implications of our results on the estimation of classical measurement error models. Then by both a Monte Carlo study and an empirical application, we show that failing to account for the nonzero probability of truthful reporting can lead to significant bias on estimation of the latent distribution.

中国创业板市场节日效应的实证分析

本文回顾了创业板市场建立过程,以香港创业板与深市创业板的时间序列数据,首先进行了香港创业板(GEM001)和深市创业板指(399006)对数收益率的波动性刻画,验证其分别服从GARCH(1,1)和ARCH(1)模型,且拟合优度较好;然后采用虚拟变量回归的方法,对其节日效应进行了检验,结果发现:港股在元旦、五一、春节时具有较为显著的节日效应(节前效应和节后效应);深创业板在国庆时具有较为明显的节日效应,在元旦和五一具有节前效应。最后针对创业板市场的关键问题,提出看法和建议。

How do market conditions impact price-TOM relationship? Evidence from real estate owned (REO) sales

Empirical evidence on the relationship between real estate price and selling time (time-on-market (TOM)) is mixed as to whether the price-TOM relationship is positive or negative. Competing theories also suggest opposite predictions about TOM’s impact on selling price. The article examines the price-TOM relationship against the background of varying market conditions and highlights the impact of these conditions on the relationship. The theoretical analysis extends search theory and Lazear’s model to changing market conditions and reconciles their predictions on the relationship. The empirical analysis refines the investigation of the price-TOM relationship by revealing the cross-effect of market conditions and TOM on price. The findings confirm that the price-TOM relationship can indeed be positive or negative depending on these conditions. However, except for the case of an extremely bad market, the relationship is generally positive. This outcome occurs because search effort (indicated by TOM) brings significant price benefit that is large enough to offset all but the worst market price declines. Additional analysis confirms that the findings are not altered by the potential endogeneity between price and TOM.

组织环境因素对中小物流企业人力资源管理行为影响的实证分析

从组织环境因素的角度研究了其对中小物流企业人力资源管理行为的影响,将组织环境因素分为企业经营规模、企业发展战略以及与大企业的联盟关系三个维度,并从这三个维度出发分别研究了其与企业的核心团队组成结构比例、教育培训方式和投入程度、绩效考核体系规范性及员工工资薪酬水平等之间关系的相关性,通过对调查问卷获得的实际样本数据进行统计分析,认为企业发展战略以及与大企业的联盟关系对于中小型物流企业人力资源管理行为的影响比较显著,而企业经营规模对人力资源管理行为选择的影响相对较小.
