多层次资本市场的产业内涵

资本市场已经成为人们关注的焦点。然而,我们需要什么样的资本市场是我们理论与实践中必须解决的问题。本文从资本市场的本质特征出发,研究资本市场长期选择功能发挥的前提在于建立多层次的资本市场;从理论上证明多层次资本市场在产业层面上所产生的巨大作用;从发达国家的经验上说明多层次资本市场对主导产业形成的影响;最后提出发展多层次资本市场的对策。     

管理层收购作为当前风险投资退出方式的分析

中国风险投资业已步入高速发展的阶段。风险资本的融资渠道正在拓宽,投资主体也正在向多元化发展。然而,与此相对的风险投资退出机制却仍不健全。结合我国当前风险投资行业R现状,从管理层收购这种形式讨论了风险投资退出机制的问题。     

Location of industry, market size, and imperfect international capital mobility

This paper examines the impact of imperfect international capital mobility on an industrial location when increasing returns are present. When the international capital mobility is perfect, agglomeration of manufacturing firms progresses with a decline in transportation costs of manufactured goods, and full-agglomeration in a large-market country is observed at low transportation costs. In contrast, when international capital mobility is imperfect, agglomeration in a large-market country progresses with capital trade integration. When the transportation costs of manufactured goods are low, all capital holders in two countries invest their capital into a home market.     

不完全资本市场与国际贸易赤字

本文通过带有风险资产的两期一般均衡模型研究了不完全资本市场和一国国际贸易之间的相关性。研究表明,当市场是完全的或者没有风险资产时,一国的国际贸易是平衡的,但是当资本市场不完全时会出现贸易不平衡。如果是国家间的不完全市场,由于一些国家的收入对风险资产的回报具有更强的相关性,使得国家间的贸易出现不平衡;如果资产在一个国家内是不完全的,则由于完全市场国家具有更强的国内分散收入变化风险的能力,会减少预防性储蓄,导致更大的贸易赤字。一些国际数据基本支持本文的研究结论。     

Fama—French三因子模型与股权分置改革效应研究

本文采用Fama-French三因子模型研究了中国股权分置改革的市场效应及其影响因素。根据在2006年底已经成功实施股权分置改革的1058个有效样本,我们发现:股权分置改革的市场效应显著为正;市场效应与股改对价显著正相关,表明送股越多,越向市场传递有利的信号;股权集中度越高,市场效应越低;股权制衡度越高,市场效应越好,表明未来的控制权市场对流通股股东利益有正面影响;全面实施的公司比试点的公司有着更好的反应。这些发现为提高股票流动性,改善公司治理结构,保护投资者利益提供了实证证据。     

Disentangling Treatment Effects of Active Labor Market Policies: The Role of Labor Force Status Sequences

This paper estimates treatment effects of two active labor market policies – a training program and a wage subsidy scheme – on participants' employment probabilities. The analysis is based on unique data from the 18th wave of the Polish Labor Force Survey containing detailed and extensive individual labor force status histories. We discuss two variants of an exact covariate matching procedure adapted to the specific nature of the data. Our study confirms and reinforces a point raised in recent research [Heckman, J.J., Smith, J.A. The Pre-programme Earnings Dip and the Determinants of Participation in a Social Programme: Implications for Simple Programme Evaluation Strategies. The Economic Journal 1999; 109; 313-348., Heckman, J.J., Smith, J.A. The Determinants of Participation in a Social Program: Evidence from a Prototypical Job Training Program. Journal of Labor Economics 2004; 22; 243-298.], that pre-treatment labor force status dynamics play a decisive role in determining program participation. We implement a conditional difference-in-differences estimator of treatment effects based on these individual trinomial sequences of pre-treatment labor market status. The estimator employs a “moving window” technique that nicely controls for changes in the macroeconomic environment over time. Our findings suggest that training raises individual employment probability, while wage subsidies display negative treatment effects for participants in the Polish case.     

Earnings management, lawsuits, and stock-for-stock acquirers’ market performance

There is a positive association between stock-for-stock acquirers’ pre-merger abnormal accruals and post-merger announcement lawsuits. The market only partially anticipates the effects of post-merger announcement lawsuits at the merger announcement and the post-merger announcement long-term market underperformance is largely limited to litigated acquisitions. Overall, the evidence suggests that it is important that investors not only undo the direct stock price effects of earnings management but also factor the contingent legal costs associated with earnings management.     

我国保本基金保值效果的比较研究

本文简要介绍了保本基金的三种投资策略,并在此基础上对我国目前发行的五只保本基金的投资策略及资产配置原则进行了描述并作出评价.本文从理论上对各基金投资策略的有效性进行论证后,又通过数据对其保本效果进行了检验.利用图形与数据,比较了其价值增长线的有效性,基金净值变化的波动性,股票仓位变动的合理性,并通过各项指标,借助主成分分析法,对各基金在一定风险下的收益进行了比较.     

行为金融学对我国企业资本结构研究的借鉴作用

行为金融学在资本结构研究方面的主要成果包括市场时机理论和非理性经理人的管理模式。行为金融学的理论发展对我国企业资本结构的研究在理论依据、研究方法以及研究视角方面都具有重要的借鉴作用,它引导研究者利用案例、理论模型和实证检验等研究方法,分析我国的融资案例和投资行为,同时也为我国决策管理层合理预期资本市场形势制定有效管理政策提供依据。     

Relation between franking credits and the market risk premium: a comment

Based on the Officer (1994) model, Gray and Hall (2006) derive a relation between franking credits and the market risk premium. On the basis of this relation, the authors show that traditional estimates of the value of franking credits imply dividend yields that are inconsistent with historical equity market data. This inconsistency arises from assumptions about the franking credit payout ratio and the value of franking credits retained. With less than a 100 per cent payout ratio some franking credits are retained within the firm. Assuming that the retained franking credits have no value leads to the inconsistency in dividend yields. Current practice in the application of Officer's model makes this assumption and, therefore, leads to inconsistent results. Gray and Hall suggest resolving the inconsistency by setting the value of all franking credits to zero. An alternative solution is to recognize that retained franking credits might have a positive value.
