效率与公平关系的物权法思考

在物权领域,浅层面的物权公平与物权效率并不矛盾.冲突存在于物权效率与高层面的社会公平之间,即物权效率自然发展导致起点不公平、机会不均等、结果不均衡.并且在这一交叉层面的"物权垄断"势能所产生的"马太效应"不可能熨平.通过物权社会化,让私人性物权效率提升为社会效率,则社会效率与社会公平能和谐一致.这种提升属政府管制时的限制,是在初次分配中重新界定权利,不是要素所有的分配,而且权利分配的财富调整功能优于再分配.     

引入战略投资者与我国商业银行改革

引入境外战略投资者、海外上市几乎成了目前国有商业银行股份制改革的必经之路，但这种改革模式正引起广泛争议。我国商业银行在推进股份制改革过程中引入境外战略投资者，有其深刻的经济背景；外资金融机构对中资银行进行股权投资，也有其种种动因。国有银行把部分股权卖给外资战略投资者，其究竟算不算“贱卖”，最终还得通过市场实践才能得以验证。     

审计报告改革对权益资本成本的影响研究

传统审计报告的模式化披露无法满足投资者价值信息获取需求,“审计期望差距”问题日益严重。基于2016年12月颁布的新审计报告准则,选取A+H股上市公司为研究对象,考察审计报告改革对上市公司权益资本成本的影响。结果表明,审计报告改革会显著降低权益资本成本。进一步发现,关键审计事项披露数目越多,权益资本成本越低;审计报告改革降低权益资本成本的效应在信息不对称程度高、内部控制水平低、媒体环境差以及代理冲突高的公司中更为明显。这不仅为审计报告改革的经济后果提供了证据,而且对于提高投资者决策效率以及维护资本市场秩序也具有一定的现实意义。     

多重关联下PE/VC持股对公司财务风险影响的传导效应

在资本结构、股权结构及市场价值三类多重关联关系下,研究了我国PE/VC持股对公司财务风险影响的多重传导效应。实证检验表明：我国PE/VC的介入会加剧其持股公司发生财务风险的危机,且在该影响过程中,资本结构波动和市场价值波动会增加公司财务风险,而股权结构波动可抑制公司财务风险发生。同时,股权结构波动的遮掩效应最为显著,资本结构波动次之,而市场价值波动的遮掩效应最弱。此外,这三类潜变量在该影响过程中的多重传导效应存在上市板块差异。     

控股股东股权质押、市场化水平与公司风险承担

聚焦微观企业,以我国A股上市公司为样本,研究了控股东股权质押对上市公司风险承担的影响。研究发现：（1）控股股东股权质押正向影响上市公司的风险承担水平,且这种影响在控股股东持股比例较低和所处地区市场化程度较高的公司中更为显著。（2）控股股东股权质押对上市公司风险担的正向影响只有在股权质押率较高和公司存在融资约束时才会发挥作用。（3）上市公司风险承担的提高可以促进公司价值的提升,有助于公司的长远发展。     

互联网金融视角下股权众筹融资的投资风险探析

股权众筹是公司通过出让股份获得资金的一种融资方式,它的出现很大程度上解决了中小型企业融资难、融资贵的问题。但是近年来股权众筹的发展速度逐渐放缓,同时模式本身也暴露出了较高的投资风险。针对这些投资风险,论文从退出机制、外部审计和监管三个层面给出了相应的措施建议。     

Reconciling sustainability and discounting in Cost–Benefit Analysis: A methodological proposal

The incorporation of the intergenerational equity objective has rendered the traditional Cost–Benefit Analysis (CBA) approach obsolete for the evaluation of projects presenting an important number of environmental externalities and for those whose impacts extend throughout a long period of time.Based on the assumption that applying a discount rate rewards current consumption and, therefore, that it is only possible to introduce a certain intergenerational equity in a Cost–Benefit Analysis, in this work we propose an approach to discounting based on a different rationale for tangible and intangible effects. We designed two indicators of environmental profitability: a) the Intergenerational Transfer Amount (ITA), which quantifies in monetary units what the current generation is willing to pass on future generations when an environmental restoration project is carried out, and b) the Critical Environmental Rate (CER), measures the implicit environmental profitability.These concepts were tested through an empirical case study pertaining to the assessment of an Erosion Control Project in the southeast of Spain. The results yield traditional profitability indicators that are higher — and probably closer — to the real values set by the contemporary society. The information provided by the environmental profitability indicators proposed renders more transparency to the quantification of the levels of intergenerational equity applied, thereby facilitating the difficult reconciliation of the CBA technique with the objective of sustainability.     

Risk Aversion, Intergenerational Equity and Climate Change

The paper investigates a climate-economy model with an iso-elastic welfare function in which one parameter measures relative risk-aversion and a distinct parameter measures resistance to intertemporal substitution.We show both theoretically and numerically that climate policy responds differently to variations in the two parameters. In particular, we show that higher but lower leads to increase emissions control. We also argue that climate-economy models based on intertemporal expected utility maximization, i.e. models where = , may misinterpret the sensitivity of the climate policy to risk-aversion.     

Intertemporal Equity and Efficient Allocation of Resources

Competitive paths which are efficient are shown to satisfy a terminal cost minimization condition, thereby providing a continuous-time counterpart to the discrete-time result due to Malinvaud. Using this result, competitive paths which are equitable and efficient are shown to satisfy Hartwick's investment rule, which states that the value of net investment is zero at each date. Our result indicates that Hartwick's rule can help to signal inefficiency of competitive equitable paths. Journal of Economic Literature Classification Numbers: C61, D90, O41.
