NOT REPORTING A PROFIT: CONSTRUCTING A NON‐PROFIT ORGANISATION

Public sector reformers advocate contracting‐out as a means of improving cost‐effectiveness. In the health sector, market‐based contracts with for‐profit organisations can reduce equity of access and divert public funds to private gain. Such issues have prompted policy makers to seek alternative contracting strategies. This paper examines a primary health care policy whereby government contracts with private non‐profit organisations to increase efficiency and meet World Health Organisation ideals. The study found that the policy's implementation has not achieved these aims when for‐profit providers masquerade as non‐profit organisations. The implication is that governments may find it more effective to manage for structural diversity than mandate homogenisation.     

股价波动、通货膨胀与固定资产投资——基于协整和VEC模型的经验证据

经验证据表明,我国股票市场时全社会固定资产投资的影响作用还比较小,股票市场对固定资产投资的冲击在部分时段是负效应,可能存在部分"挤出效应".而影响固定资产投资的主要因素是GDP的变动.另外在我国,通货膨胀率对固定资产投资的影响比较明显.从短期来看,固定资产投资也带动了通货膨胀.国内固定资产投资的波动不仅受偏离均衡的影响,还受到GDP、Cpi、上证综合指数与存款利率水平自身变动的影响.央行应加强审慎的宏观调控,优化信贷结构,加强农村水利建设的长期投资,为经济结构调整和经济增长方式的转变提供稳定的货币金融环境.     

权证隐含波动率在标的证券波动率预测中的作用研究

资产收益的波动是投资者投资决策的主要依据.本文选取了葛州和长虹等七只权证作为样本.首先应用单位根检验,验证各样本历史波动率和隐含波动率序列的平稳性,在此基础上检验各样本两种波动率序列的协整关系.最后,对隐含波动率所包含的额外信息进行探讨.结果表明,已实现波动率和隐含波动率基本上呈现单位根状态,并且两者之问基本不存在协整关系,权证的隐含波动率确实拥有额外的信息.投资者在实际运作中,可以加入隐含波动率来提高对实际波动率预测的准确性.     

CAPM对我国封闭式基金定价的实证检验

本文以上证封闭式基金为样本,选取2007年12至2010年11月的月度数据,采用单指数模型、BJS两步法和横截面检验实证分析了我国基金市场对CAPM的适用性。CAPM并不适用于我国基金市场,原因在于基金市场的不成熟以及投资主体投资理念的非理性。同时CAPM条件过于苛刻,在对资本市场进行检验时应谨慎对待。     

城市住宅价格与宏观经济变量的关系分析——基于VAR模型的实证研究

通过分析选取住宅价格指数(HPI)、国内生产总值增长率(GDP)、1-3年期银行贷款利率(IR)作为内生变量,滞后两期的广义货币供应量(M2)作为外生变量,建立了向量自回归模型。并在此基础上,运用协整分析、脉冲响应函数、方差分解和格兰杰因果检验等研究方法对住宅价格指数与宏观经济变量之间的动态相关关系进行了研究。研究结果表明,我国的住宅价格与所选用的宏观经济变量之间存在一定交互响应作用,并就此提出了相关建议。     

我国主要海洋产业对劳动力就业的拉动效应分析

就业问题事关国计民生.积极寻找新的就业增长点,缓解当前就业压力,促进经济稳定增长已成为政府、学者和公众关注的焦点话题.本文以我国主要海洋产业为研究对象,从就业弹性和单位岗位贡献两个角度出发,对主要海洋产业的就业拉动效应做出分析.研究结果表明:我国主要海洋产业生产总值每提高1%,将使主要海洋产业就业人数增加3.28万人次;就业弹性显著为正,但呈现出下降的趋势;主要海洋产业群内部各子产业的单位岗位贡献差异明显,其中海洋交通运输业和海洋油气业对就业的带动作用较大,且传统优势产业海洋渔业、滨海旅游业等仍扮演重要角色.     

中国银行业的利润效率研究——基于傅里叶柔性函数的视角

商业银行的经营效率已成为近年来国内外学者研究的热点问题。本文尝试引入傅里叶柔性函数模型测算我国银行业的效率水平,为更加准确地判断商业银行的经营效率提供依据。研究表明：傅里叶函数模型拟合效果要优于超越对数函数模型;1999—2009年,我国商业银行的利润效率估计均值为0.9466,总体效率水平较高。     

The implementation and structuring of divestitures: the unit's perspective

Existing literature on value creation of divestitures focuses on their antecedents, typically relating them to the parent company's financial performance. Whether and how divestitures can create value for the divested unit remains unclear. This paper presents an exploratory study based on multiple cases, to examine which factors of the implementation and structuring of a divestiture may increase the performance of a divested unit. The emergent granular framework consists of previously unreported aspects of the divesting process and provides new insights into divestitures and their outcomes. Results indicate that antecedents alone may be insufficient for understanding the outcomes of divestitures. Different combinations of understanding of the rationale for the divestiture and perceived capabilities in the divesting process affect perceptions of divestiture feasibility. Sense of opportunity emerges as the key element of the divesting process for the success of divested units. Factors that participate with sense of opportunity in determining the success of divested units are further considered in the theoretical framework. Copyright © 2010 John Wiley & Sons, Ltd.     

The value of relational learning in global buyer‐supplier exchanges: a dyadic perspective and test of the pie‐sharing premise

Research in collaborative interorganizational relationships has typically focused on the value of these relationships to a specific supply chain partner. Furthermore, the phenomenon has rarely been explored in a global setting. Using primary data from 126 cross‐border dyads, we investigate the influence of relational learning on the relationship performance of both the buyer and the supplier, testing the contention that both members (1) benefit from relational learning efforts and (2) enjoy equal pieces of the benefits pie. We find that three specific types of relational learning (information sharing, joint sensemaking, and knowledge integration) influence relationship performance, and that these dimensions of relational learning affect supply chain partners in different ways. We draw conclusions regarding the relative value of relational learning for both buyers and suppliers. Copyright © 2011 John Wiley & Sons, Ltd.
