企业家战略--培育创新能力的企业内部战略

近几年来,在超强竞争背景下国外兴起的企业家战略,是公司努力将组织各个层次的员工培育为普遍具有企业家精神、思维和行动的战略,是努力将整个公司转变为能够发挥员工企业家精神的战略.企业家公司以异质的企业家人力资本和企业家智力资产持续创新,破坏均衡,产生竞争优势和显著的业绩.企业家战略理论研究的是公司如何获得具有创新、变革、远见卓识和承担风险的能力,是对正在兴起的内部战略理论的丰富和发展.企业家战略与核心能力理论互相补充,并且改变了某些传统的战略管理观念.     

中国国民财富总量、结构及其演进模式研究——基于“自上而下-自下而上”测度范式

“财富-福利等式”表明国民财富与社会福利具有理论等价关系,是评估发展可持续性的最优指示器。我国国民财富研究相对滞后,总量测度与结构分析都亟待深化。本文基于“自上而下-自下而上”范式,依据国情优化关键参数的设定,改进了我国国民财富与分类资本估算,并剖析了省际国民财富结构以识别其演进模式。研究发现:由于资源禀赋与发展阶段有别,省际国民财富结构差异显著;随着经济发展水平提升,国民财富结构先由自然资本主导转向物质资本与人力资本共同主导,进而转变为人力资本主导,最终迈入社会资本主导。各地区应结合自身禀赋与发展阶段做好“投资组合管理”,以此来提升国民财富并优化其结构从而改善经济发展的持续性。

后现代主义视角下对社会工作谋求专业合法性的思考

在政策的推广下,社工的合法性建设在中国如火如荼地开展。本文将合法性建设置于场域—惯习理论下进行检视,并从后现代女性主义理论视角出发,认为合法性惯习可追溯到男权制文化的建构,实际上是社会场域中的"男性资本"的要求。社会工作的发展在受到场域的男性规则阻碍的同时,又在利用其改变自己在场域中的利益位置。笔者在文章中论述了攀附男性资本的发展只是自缚手脚,并提出建立"社会工作气质"。     

小组工作介入聋儿社会资本的重构

社会资本在聋儿成长中具有非常重要的作用。重构聋儿社会资本成为社会康复的核心内容。在聋儿听力康复过程中,由于聋儿游戏群体的缺失、家长的认识偏误以及家长社会资本的不足等原因,导致聋儿社会资本不足的问题非常突出。文章从小组工作视角出发,提出通过组建聋儿游戏群体,增进聋儿家长社会资本,重构聋儿社会资本的建议。     

Optimal control strategies for dividend payments and capital injections in compound Markov binomial risk model with penalties for deficits

We consider the compound Markov binomial risk model. The company controls the amount of dividends paid to the shareholders as well as the capital injections in order to maximize the cumulative expected discounted dividends minus the discounted capital injections and the discounted penalties for deficits prior to ruin. We show that the optimal value function is the unique solution of an HJB equation, and the optimal control strategy is a two-barriers strategy given the current state of the Markov chain. We obtain some properties of the optimal strategy and the optimal condition for ruining the company. We offer a high-efficiency algorithm for obtaining the optimal strategy and the optimal value function. In addition, we also discuss the optimal control problem under a restriction of bounded dividend rates. Numerical results are provided to illustrate the algorithm and the impact of the penalties.     

Shadow Insurance

Life insurers use reinsurance to move liabilities from regulated and rated companies that sell policies to shadow reinsurers, which are less regulated and unrated off‐balance‐sheet entities within the same insurance group. U.S. life insurance and annuity liabilities ceded to shadow reinsurers grew from $11 billion in 2002 to $364 billion in 2012. Life insurers using shadow insurance, which capture half of the market share, ceded 25 cents of every dollar insured to shadow reinsurers in 2012, up from 2 cents in 2002. By relaxing capital requirements, shadow insurance could reduce the marginal cost of issuing policies and thereby improve retail market efficiency. However, shadow insurance could also reduce risk‐based capital and increase expected loss for the industry. We model and quantify these effects based on publicly available data and plausible assumptions.     

《资本论》农业生态思想及其新时代启示

学界对《资本论》中生态思想的研究成果颇丰,却对农业生态思想研究不足。近年来我国农业生态问题频发,因而对《资本论》中隐蕴的农业生态思想进行研究显得尤为必要。《资本论》察明了农业生态问题产生的根源,剖析农业生态问题的核心并提出相应的破解之道。其农业生态思想以批判性、系统性以及革命性的鲜明特质贯穿始终,这为我国农业发展摆脱生态困境提供了相应的启示。     

The Contingent-Claims Approach to Investment Decisions*

This paper presents a contingent-claims approach to project valuation when capital expenditures are made sequentially over time. It focuses on an important facet of sequential investment projects that the firm can undertake—or pass up projects—as more information becomes available. The contingent-claims approach takes account of this important feature of firms' investment decision process, whereas the traditional capital budgeting procedure does not. Since the traditional method does not reflect the options nature of investment opportunities, it underestimates the value of sequential investment projects. As a result, a naive implementation of the traditional capital budgeting procedure could result in rejecting profitable projects. The extent of undervaluation associated with the traditional capital budgeting procedure is greater when the correlation between the random component of the future asset value and that of the required capital expenditure is smaller and/or when the growth rate of the required capital expenditure is higher.
