美国禁用MTBE带来的冲击及应对措施

美国汽油标准向来走在世界前列，基本引领世界清洁汽油发展潮流。四年之后全美将在汽油中禁止使用MTBE，这势必会对全球尤其是欧洲MTBE的生产、供应和使用等带来许多影响。对美国MTBE使用、生产，供应现状以及许多炼油公司采取的应对措施的详细描述，有助于我国汲取国外汽油发展的先进经验，在汽油标准制定和生产上少走弯路，及早投入MTBE替代工艺的研究，填补我国在这一领域的空白。     

从市场功能看我国货币市场结构的合理性

从市场要素角度看,我国货币市场结构的合理性已大大提高,但市场发展的最终目的是要充分发挥其特有的功能,因此有必要进一步从功能角度考察我国货币市场结构的合理性.货币市场是企业筹集短期资金的市场,是商业银行进行流动性管理的市场,是中央银行实施金融宏观调控的市场,本文从这三个方面系统评判了我国货币市场结构的合理性.

辽宁上市公司董事会报告透明度影响因素研究

以46家辽宁上市公司为样本,对影响董事会报告透明度因素的研究发现:股权集中度、管理层持股比例、董事会规模、独立董事比例与董事会报告透明度呈正相关关系;股权制衡度,董事长与总经理是否两职合一,审计意见类型与董事会报告透明度呈负相关关系。上市公司应该通过股票期权等方式提升管理人员的持股比例,激励他们积极治理公司,提高董事会报告信息披露的透明度;上市公司第二大股东应适度提高持股比例,防止一股独大现象;同时减少董事长与总经理两职合一,也会有助于提高董事会报告的透明度。     

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.     

On the tax bias against investments in fixed assets: Empirical evidence from China

China's new Corporate Income Tax Law was passed in March 2007 and took effect on 1 January 2008. We take advantage of this tax law change and use a difference‐in‐differences approach to empirically estimate the impact of taxation on asset structure. Employing the Chinese Industrial Enterprises Database from 2002 to 2008 to implement the analysis, we find evidence suggesting the presence of tax bias against investments in fixed assets. We address two potential concerns about our analysis and argue that our conclusion is not China‐specific; it is a general lesson for modern finance theory that is portable to developed countries.

IMMEDIATE SETTLEMENT OR ENDURING A STRIKE: THE CHOICE OF SIGNALS

Some labour contract negotiations involve strikes while most conclude with immediate settlement. This article offers a model of union‐firm negotiation with private information to show that either strikes or immediate settlement will take place in the equilibrium. Different from most signalling literature where the signals are exogenously given, this article endogenizes the choice of signals. We compare two signals, the employment level and the strategic delay. We show that the low‐revenue firm will choose the signal which gives it higher payoff while separating itself from the high‐revenue firm.     

经济政策主要变量对控制中国失业率有效性的实证检验

随着中国经济的增长,失业率却一直居高不下,因此国家采取各种手段进行宏观调控。在回顾各种经济学派对失业理论研究的基础上,着眼于经济政策对控制失业率是否有效,在简要分析货币政策和财政政策对失业率影响的基础上,选取1991—2011年中国城镇登记失业率、货币发行量以及财政支出,通过对三者进行单位根检验和Johansen协整检验,得到三者存在唯一的协整关系,并建立误差修正模型,得出货币发行量对失业率影响较大并且较稳定的结论,并通过格兰杰因果检验,得出货币发行量和财政支出与失业率之间都不存在因果关系,最后在实证研究的基础上对当前中国如何控制失业率提出相应的对策。
