    公司资本结构的影响因素是什么是现代金融经济学一个最基础的问题。虽然已有大量理论文献认为税收、破产成本、代理成本、规模以及成长机会均是潜在的影响公司资本结构的因素,但是要完全地理解公司的融资决策还需要进一步的研究。 税收是影响公司资本结构的重要因素,关于税收和公司资本结构之间的关系在理论上已得到了广泛的研究。这些文献强调了公司所得税税率、非债务税盾与最优公司资本结构之间的关系,并提出了一些可供检验的理论假说(如Barnea、Haugen和Senbet,1981;DeAngelo和Masulis,1980;Miller,1977;Modigliani和Miller,1958、1963等)。 但...What are the determinants of the firm's capital structure is one of the fundamental questions of modern financial economics. A large number of theoretical literature consider that taxes, bankruptcy cost, agency cost, size and growth opportunities are the potential factors which determine the firm's capital structure, but to fully understand the financing decisions of firm needs further study.

    中国经济的高速增长与居民收入不平等现象一直以来都是学界研究的热点问题。本文认为居民收入不平等对中国经济增长有着重大的负面影响并且人力资本积累是收入不平等影响中国经济增长的主要因素。本文建立了一个以世代交替模型为基础的研究框架,在假定收入和能力是异质的条件下,更公平的收入分配意味着更多人力资本积累和更快经济增长。同时,本文利用1978-2009年中国各省的面板数据对模型进行了检验。实证结果证实了更公平的收入分配有利于人力资本积累和经济增长这一假设,同时,还表明人力资本积累是收入不平等不利于经济增长的主要因素

    本文以2003—2011年沪深A股为样本,考察机构投资者对股市波动性及股票收益的影响。本文研究结果表明:(1)机构投资者持股比例的提高加剧了股票的波动,但股票波动加剧并不会吸引更多的机构投资者;(2)机构投资者持股比例提高会增加当期股票收益,机构投资者持股比例的净增加会显著提高下期股票收益率;(3)机构投资者持股比例较高的资产组合当期夏普比率较高,但机构投资者持股比例较高的资产组合下期夏普比率较低。国家杰出青年科学基金项目(批准号:70825003); 国家社会科学基金重点项目(批准号:07AJL002);国家社科基金重点项目(批准号:12AGL008); 西南大学中央高校基本科研项目(批准号:SWU1209359和SWU1209390); 厦门大学中央高校基本科研业务费项目(批准号:2009ZK1007)的研究成

    本文利用1978~2006年的面板数据和随机前沿的分析方法测算了中国地方税收征管效率。实证结果表明:首先,实物资本和经济效率显著地促进了地方税收增长,而"分税制"改革则显著地抑制了地方税收增长;其次,我国各地区的税收征管效率普遍较低,我国东部地区的税收征管效率普遍要比中西部地区的税收征管效率要高;再次,本文的实证结果表明税收征管效率与市场发育程度紧密相关,市场发育越完善的地区,税收征管效率也就越高

    金融发展能减少城乡收入差距吗?——来自中国的证据

    No full text
    已有的实证分析普遍认为金融发展有利于经济增长并减少城乡收入差距。本文利用中国1978~2006年各省的面板数据予以检验。实证结果表明,金融发展显著地扩大了城乡收入差距;并和农村居民收人增长显著负相关,金融发展和城市居民收入增长之间不存在显著相关关系;最后,金融发展和经济增长不相关。Existing literatures generally show that financial development boosts economic growth and narrows urban -rural income gap.Using the panel dataset of China from 1978 to 2006,the paper examines the impact of financial development on income distribution.The empirical results are as follows.First,financial development significantly boosts urban-rural income gap.Second,financial development reduces the income of rural residents and there is no significant correlation between financial development and income growth of urban residents, which is the reason why financial development boosts urban-rural income gap.And finally,financial development and economic growth are not correlated.国家杰出青年基金(项目批准号:70825003);国家社会科学基金重点项目(项目批准号:07AJL002)的资

    拓展JIAng和TIAn[1]模型获得了看涨看跌期权的无模型隐含波动率的理论表达式.并对理论表达式做了进一步处理,获得满足实际应用需要的计算表达式.根据无套利原理,由当前商业银行不同期限存贷款利率构造出不同执行价的看涨和看跌期权,再运用3次曲线拟合的方法,获得满足实际应用需要的一系列看涨和看跌期权;最后计算得到5年期定期存贷款利率的隐含波动率.研究结果表明我国当前银行存贷款利率存在上涨压力.This paper extend Jiang and Tian(2005) model to the setting for put options,and obtain the expressions of the model-free implied volatility of call options and put option.And we further transform the theoretical expressions to those which meet practical application needs.According to no-arbitrage principle,we construct calls and puts with different strike prices using the deposit and lending interest rates with various maturities and then we acquire a series of calls and puts through cubic curve fitting method.Finally we work out the implied volatilities of five-year deposit and lending interest rates.Our results show that there exists a upward pressure in the interest rates of deposit and lending of China's banks.国家社会科学基金重点资助项目(07AJL002);国家杰出青年科学基金资助项目(70825003
