大股东对上市公司掏空与支持的经济学分析

在公司的所有权安排中,大股东拥有公司的控制权,有能力为获取控制权的私人利益而侵占上市公司的资源。但是,当上市公司陷入经营困境时,大股东可能通过减少自己的侵占行为而使公司具有偿债能力,甚至会用自己的资源进行支持以防止公司破产。如果上市公司的投资回报率低于大股东的预期水平,或者预期上市公司无法继续生存下去时,大股东会以公司外部股东和债权人的利益为代价而对上市公司进行掠夺。     

基于企业动态联盟的界面管理研究

界面管理是企业管理创新研究的新趋向，动态联盟是近年来企业组织关系中最重要的制度创新，本文将界面管理概念引入动态联盟组织模式中，分析了影响动态联盟界面整合的四个关键要素，并简要地指出了动态联盟界面管理有待进一步深入的研究方向。     

基于主成分分析法的人类发展指数替代技术

在本文中,我们采用基于协方差的主成分分析法来分析1990年以来UNDP发布的中国人类发展数据,然后采用Spearman秩相关系数来分析获得的主成分与HDI之间的关系。研究表明,主成分分析法不仅能够有效地替代传统的人类发展指数编制方法,其形成的动态权重结构还可以有效地透视人类发展差距模式的历史演进过程,以及人类发展的各个方面(如预期寿命、知识教育和体面的生活等)在整体发展进程中的角色变化。对中国人类发展数据的分析结果也表明,尽管1990年以来中国各地区在经济、教育和健康方面均取得了重大进步,但三项发展之间存在着严重的不协调,地区发展差距也越来越多地体现为经济发展差距,这些反映了改革开放以来中国各级政府过分强调经济增长而带来的片面、不协调的人类发展。实现经济社会的协调发展,是时代的要求,也是当前我国各级政府面临的主要任务。而强调公共服务职能、推动地方政府的服务型转型,是消除不平衡发展的关键。

可转债分拆交易研究——台湾经验借鉴与国内创新

本文旨在对可转债分拆交易的理论研究和台湾实践经验进行梳理的基础上,为国内可转债分拆的交易框架和定价设计提供借鉴。本文的结构安排如下:首先,对可转债分拆交易的相关文献进行综述;其次,阐述可转债分拆的交易结构与理论定价;再次,介绍台湾可转债分拆交易的现实定价与法律框架;最后,结合国内的发展现状,提出国内可转债分拆交易的相关制度设计框架,并给出了进一步的政策建议。     

中国经济真的动态无效吗

史永东与杜两省、史永东与齐鹰飞、袁志刚与何樟勇相继考察了中国经济的动态效率,结果均表明中国经济是动态无效的.本文首先通过实证研究进一步检验上述结论,并进而追问中国经济为什么会发生动态无效.笔者的分析表明,这种无效性只是一种表象,它是由我国的粗放式经济增长方式决定的,其根源在于静态资源配置,特别是投资配置的无效性.在此基础上,本文进而指出,上述作者提出的消除无效性的政策建议是不恰当的,真正有效的途径只有转变增长方式,提高增长绩效.     

The Future of Financial Reporting: Insights from Research

Research offers insights that, if heeded and built upon, could improve financial reporting, thereby contributing to a more prosperous society. In particular, research suggests improvement could stem from greater use of fair value; a performance statement designed to reveal the information embedded in changes in fair value; better information to help investors assess the value of intangible assets; more specific information about risk and uncertainty; information that is unbiased, rather than conservative; acceptance of a degree of earnings management together with a determination of how much earnings management is acceptable; and a financial reporting package designed to convey information users need, which presumably is broader than today's financial statements.     

Learning minimum variance discrete hedging directly from the market

Option hedging is a critical risk management problem in finance. In the Black–Scholes model, it has been recognized that computing a hedging position from the sensitivity of the calibrated model option value function is inadequate in minimizing variance of the option hedge risk, as it fails to capture the model parameter dependence on the underlying price (see e.g. Coleman et al., J. Risk, 2001, 5(6), 63–89; Hull and White, J. Bank. Finance, 2017, 82, 180–190). In this paper, we demonstrate that this issue can exist generally when determining hedging position from the sensitivity of the option function, either calibrated from a parametric model from current option prices or estimated nonparametricaly from historical option prices. Consequently, the sensitivity of the estimated model option function typically does not minimize variance of the hedge risk, even instantaneously. We propose a data-driven approach to directly learn a hedging function from the market data by minimizing variance of the local hedge risk. Using the S&P 500 index daily option data for more than a decade ending in August 2015, we show that the proposed method outperforms the parametric minimum variance hedging method proposed in Hull and White [J. Bank. Finance, 2017, 82, 180–190], as well as minimum variance hedging corrective techniques based on stochastic volatility or local volatility models. Furthermore, we show that the proposed approach achieves significant gain over the implied BS delta hedging for weekly and monthly hedging.     

Innovation in start-ups: Ideas filling the void or ideas devoid of resources and capabilities?

We investigate how access to different types of resources affects the success of entrepreneurial start-up firms at early stages of development in small isolated economies by studying 12 start-ups based in New Zealand. We find that successful commercialization of innovations depends on the availability of complementary assets, and that capability-based resources, especially dynamic capabilities, have a greater impact on competitive advantage of start-ups than other intangible and tangible assets. For the start-ups in our study, alliances with partners are particularly important, and so the ability to form alliances is a key capability. Successful start-ups leverage their available resources to attract alliance partners in order to access necessary complementary resources. The start-ups in our study clearly demonstrated the ability to attract partners locally but struggled to do so internationally, thereby limiting their growth potential.     

Dynamic capabilities and entrepreneurial management in large organizations: Toward a theory of the (entrepreneurial) firm

Mainstream economic theory has generally excluded consideration of the role of managers, which has, in turn, impaired its ability to explain resource allocation by, and heterogeneity among, firms. In the real world, managers are called on to fill entrepreneurial and leadership roles: sensing opportunities, developing and implementing viable business models, building capabilities, and guiding the organization through transformations. These entrepreneurial management tasks are part of the organization׳s capabilities, which also encompass embedded organizational processes that can be slow to change. An understanding of entrepreneurial management and organizational capabilities will contribute to more realistic economic models and a better understanding by policy makers of industrial dynamics and the requirements of innovation.
