基于网络规划的道路系统设计

针对物流系统设计，基于网络规划法提出了一种在物流中心已经确定的条件下，进行道路系统的新的设计方法。通过合理但设把道路系统的设计转变为网络规划中求解最短路径的问题．通过统计每个路段的最短路径通过率．得出路段的运量负担情况，从而为道路的功能和等级设计提供依据。在此基础上．以宁波化工区的物流系统为例，建立了宁波化工区道路系统的网络模型，对宁波化工区的道路系统进行了功能设计。结果表明，该方法在区域物流系统设计中有良好的应用前景．     

Monotonizing empirical Bayes estimators for a class of of discrete distributions with monotone likelihood ratio

A procedure is given for the construction of a monotone estimator that dominates a given estimator for a class of discrete distributions with monotone likelihood ratio. This procedure is applied to some empirical Bayes estimators. Monte Carlo results are given that demonstrate the usefulness of monotonizing.     

Extraction of an Exhaustible Resource: The Effects on Investment of Several Parameters Being Subject to Uncertainty*

This article shows that the effect on investment of the introduction of uncertainty about the size of one parameter depends on what other parameters are simultaneously uncertain. Further, two parameters may be linked with positive or negative covariances. The covariances are here shown to have important effects on the investor, whether risk neutral or risk averse. Governments are advked to consider policies that affect the covariances of those parameters that are key influences on in vestment.

论独立董事的制度创新 --第三方法人独立董事制度设计

现行独立董事制度的结构性缺失及其作为自然人的独立董事之不独立与非理性迫切需要一个介于独立董事个人与上市公司之间的法人机构来平衡二者的关系,从而真正发挥独立董事在公司治理中的作用。而第三方法人独立董事制度安排旨在培育“职业(专业)独立董事”,使独立董事有可以归属的第三方法人独立董事公司,确保独立董事的“独立性”,从组织的角度改变个人与法人之间关系中的不均衡博弈,为独立董事职业理性的保持提供保障。同时,独立董事公司亦受到多方关系制约,使其正确有效地履行职能。     

Masculinity,Testosterone, and Financial Misreporting

We examine the relation between a measure of male CEOs’ facial masculinity and financial misreporting. Facial masculinity is associated with a complex of masculine behaviors (including aggression, egocentrism, riskseeking, and maintenance of social status) in males. One possible mechanism for this relation is that the hormone testosterone influences both behavior and the development of the face shape. We document a positive association between CEO facial masculinity and various misreporting proxies in a broad sample of S&P1500 firms during 1996–2010. We complement this evidence by documenting that a CEO's facial masculinity predicts his firm's likelihood of being subject to an SEC enforcement action. We also show that an executive's facial masculinity is associated with the likelihood of the SEC naming him as a perpetrator. We find that facial masculinity is not a measure of overconfidence. Finally, we demonstrate that facial masculinity also predicts the incidence of insider trading and option backdating.     

Identifying Price Reviews by Firms: An Econometric Approach

Price reviews are a potentially costly activity. A significant fraction of unchanged prices may stem from firms not reviewing prices, rather than from obstacles to changing prices per se, such as menu costs. In this paper, we disentangle these two causes of price stickiness by estimating an inflated ordered probit model on a panel of French manufacturing firms. The results point to a low frequency of price reviews, suggestive of the relevance of information costs as a determinant of the observed price stickiness. In view of the “inattentive producers” literature, pointing that the source of price rigidity matters, this is suggestive of a large real effect of monetary policy.     

Language Skills and the Earnings Distribution Among Child Immigrants

In this paper, we estimate the language effects on the earnings distribution among child immigrants. Utilizing U.S. Census data, we find: (1) there exists a larger heterogeneity in language premiums across the earnings distribution, and the patterns change over time (2) occupation and education channels explain most of the language effects and the large heterogeneity in them. However, the importance of these two channels has decreased over time.
