随机利率下的复合Poisson-Geometric风险模型及破产概率

本文主要研究的是在随机利率下保费收入为复合Poisson-Geometric过程的风险模型,在随机利率为levy过程的情况下,得到了破产概率满足的积分方程,以及得到最终破产概率的上下界所满足的积分不等式,以此作为保险公司经营的预警信号更具有现实意义。     

如何防范房地产危机

房地产开发中的泡沫现象,主要是指土地和房屋价格极高,与其使用价值(市场基础价值)不符,虽然账面上价值增长很高,但实际上很难得到实现,形成一种表面上的虚假繁荣.

双重古诺竞争下的FDI关联溢出效应

扩展了以往理论研究的基本假设,在古诺竞争框架下分析FDI进入东道国上下游双边市场时的关联溢出效应。结果显示:当FDI仅进入东道国的下游市场时,FDI产生的竞争效应会增加下游市场的总产出,从而增大对上游市场中东道国本土供应商的后向关联程度,且其增大程度与技术差距正相关;在FDI同时进入东道国上下游双边市场的情况下,上游市场的FDI会对东道国本土供应商产生挤出效应,且两者的技术差距越大,挤出效应越明显,同时会对下游市场中的东道国本土生产者产生明显的前向关联,上游市场总产出的增加使得中间产品的均衡价格下降,直接减少了下游本土生产者的边际生产成本,从而增加了其产出和利润,部分抵消了下游市场的FDI的挤出效应。     

合作意愿对产学研协同创新成果转化的作用研究

以企业为创新主体开展产学研协同创新已逐步成为共识,产学研协同创新合作意愿已达到空前的高度,产学研协同创新投入得到不断增加。但是,产学研协同创新成果转化效果却不尽人意,较强的协同创新合作意愿没有带来较高的协同创新成果转化。为此,必须弄清合作意愿是如何作用于产学研协同创新成果转化的。通过调查问卷收集数据并运用结构方程模型深入探究了合作意愿对协同创新成果转化的作用机理,发现产学研合作意愿对成果转化不具有显著正向影响,合作意愿作为产学研协同创新的前提,是成果转化的必要条件,而不是充分条件。最后,依据研究结论提出了有关政策建议。     

生态农场绿色发展影响因素研究——基于119个生态农场的调研数据

基于黄淮海地区北京、山东和河北三地119个生态农场的调研数据,通过统计描述阐释生态农场特征,并借助Probit模型,以生态农场绿色生产为切入点,探讨如何推动生态农场绿色发展.结果 表明:相对于一般农业经营主体而言,生态农场负责人相对年轻,受教育水平更高,拥有良好的环保、健康和市场意识,且普遍采用多种绿色生产措施;生态农场绿色生产作为绿色发展的重要内容,不仅受到负责人个体特征、农场生产经营特征等内生因素影响,也会受到政府绿色生产补贴特征、监管者质量管控特征等外生因素影响.鉴于此,在促进生态农场发展相关政策制定过程中,不仅需要关注农业从业者环保健康意识提升和人力资本水平提高,还应进一步增强绿色生产激励的可持续性,完善质量管控措施.     

Professionals inside the board room: accounting expertise of directors and dividend policy

Directors’ personal attributes have significant impacts on governance effectiveness. We study whether directors’ accounting expertise affects corporate financial policy and investigate dividend in specific. We construct a dataset of audit committee directors’ accounting expertise for Standard & Poor 500 firms from 2005 to 2012. We first verify directors’ monitoring roles by showing that firms with accounting expert sitting on their audit committees demonstrate stronger accounting conservatism. In our main tests, we find that these firms maintain lower dividend payment level, which are less sensitive to earnings volatility. This suggests directors’ advisory roles in financial policy. We further show that our accounting expertise cannot be subsumed by management ability. In additional test, we further examine the baseline results conditional on analyst forecast error. Our findings highlight the importance of directors’ professional expertise in fulfilling their governance roles.     

Consumption Inequality in China: Theory and Evidence from the China Health and Nutrition Survey

We investigate consumption inequality in China both theoretically by constructing a theoretical model that delineates the transmission channels by which income shocks affect consumption and empirically through an Unequally Spaced Dynamic Panel Data model estimation. We find that China is experiencing consumption inequality with the full partial insurance of consumption against both permanent and transitory income shocks, although the impact of both types of shock are larger than the case of the United States. The results are due to precautionary savings motives of the Chinese. We further document how income becomes more dispersed in China and show how the family background of a child affects his outcome to a large extent. Policy implications based on our findings are proposed.
