On Combining Partial and Incompatible Information in E-negotiation and E-arbitration

The complexity of the problems to be addressed in an e-democracy framework and the variety of involved stakeholders, with different backgrounds, views and access to information sources, lead us to consider the case in which an e-negotiation should be performed among subjects who have partial, sometimes incompatible, information and can hardly gather to discuss issues together, under the supervision of a facilitator. We propose a statistical method which addresses the issue of partial and incompatible information, merging it and then using it to get a final decision, possibly in an automatic way, through processes of e-negotiation and e-arbitration.      

不同市场结构下农村信用社经营绩效研究

本文对陕西省85家农村信用社市场份额与经营绩效的关系进行分析。整体来讲,农村信用社贷款市场份额与其经营绩效呈负相关。进一步分析不同市场集中度情况,贷款占比50%以上的农村信用社市场份额与经营绩效负相关,而贷款占比50%以下的农村信用社两指标正相关。这就表明应建立适度竞争的县域农村金融市场,以提高农信社经营效率,充分发挥其主力军作用,从而尽快构建现代农村金融体系。     

The impact of location factors on the attractiveness and optimal space shares of product categories

In this paper, we investigate the impact of location characteristics on the relative attractiveness of product categories within a store, and formulate micromarketing implications for the allocation of store space to categories. We present a framework for the impact of store and trading area characteristics on category and store performance, which integrates and extends previous geomarketing research. Building upon this framework, we propose a tractable and flexible procedure for assessing location influences, and derive optimal space allocation rules for different location profiles. Empirical application to national stores of a European retail chain confirms the differential impact of location characteristics on categories' attractiveness. Tailoring the allocation of store space to these location-based differences in category appeal leads to a significant increase in overall chain profitability.     

Anticipating,preventing, and surviving secondary boycotts

Even the best stakeholder-managed firms can suffer when they become targets of a secondary boycott, as recent headlines attest. By definition, a secondary boycott is a group's refusal to engage a target firm with which the group has no direct dispute, in an attempt to sway public opinion, draw attention to an issue, or influence the actions of a disputant. This article provides a new perspective and tools for both scholars and managers concerned with this phenomenon. Building on a stakeholder theory foundation, we examine possible actions managers can take to avoid being surprised by a secondary boycott, propose conditions that raise the probability of becoming the target of a secondary boycott, and develop four alternative approaches for managing stakeholder relationships in a world of secondary boycotts.

股东换购ETF是一种股东减持吗?——基于市场反应的角度

2019年以来,上市公司股东用所持股份换购ETF进入快速发展阶段。股东换购ETF不会直接冲击二级市场供求关系,且国有股东换购ETF被视作推动国企改革的举措。本文研究股东换购ETF比例的影响因素,发现国有企业股东换购ETF比例高于民营企业,2019年的股东换购比例与其他年份无显著差异。进一步,研究股东换购ETF的市场反应及其影响因素,发现市场反应显著为负,产权性质对市场反应不产生影响,2019年的市场反应比其他年份更为负面。研究表明,尽管股东换购ETF存在可取之处,但资本市场将此视作股东减持。2019年11月以来,监管机构开始参照股东减持规定严格监管股东换购ETF,这与本文结论一致。

信息不对称、异质性交易与企业资本结构的决定

在将信息不对称划分为内部人和外部人之间以及知情交易者和非知情交易者之间的基础上,借鉴金融市场微观结构和财务学的相关理论成果测度这两类信息不对称,使用中国上市公司的数据,考察了这两类信息不对称与企业资本结构的关系。结果表明,两类信息不对称程度越高,杠杆水平越低;前者对杠杆的影响程度在小公司中更强,而后者对杠杆的作用效果在大公司中更强。此外,股权分置改革在某种程度上降低了前者的影响程度,而提升了后者的作用效果。这表明,我国资本市场的主要问题可能已由原先的内部人和外部人之间的利益冲突,转变为知情投资者和非知情投资者之间的利益冲突。
