创业导向与创新绩效：高管团队特征和市场动态性的影响

创业导向对创新绩效的提升具有重要的影响,但创业导向与创新绩效的关系还可能受高管团队特征和市场动态性的影响。根据基于注意力的观点,对创业导向、创新绩效、高管团队的异质性、高管团队的共同愿景和市场动态性的关系进行研究,探讨高管团队的异质性和共同愿景对创业导向与创新绩效关系的调节作用,并进一步研究这种调节作用是否受市场动态性的影响。利用在广东、江苏、山东、陕西和河南5地收集的264份调查问卷,采用多元线性回归和调节效应的检验方法对研究假设进行实证检验。研究结果表明,创业导向对创新绩效有正向促进作用,高管团队的异质性有助于加强创业导向与创新绩效的关系。在稳定的市场环境下,高管团队的异质性对创业导向与创新绩效关系的调节效应更强;在不考虑环境动态性和环境动态性较低的情况下,高管团队的共同愿景对创业导向与创新绩效关系的调节效应不显著,但在动态性较高的市场环境下,可以显著地正向调节创业导向与创新绩效的关系。     

Linking Electronic Medical Records Use to Physicians’ Performance: A Contextual Analysis

Electronic Medical Records (EMR) studies have broadly tested EMR use and outcomes, producing mixed and inconclusive results. This study carefully considers the healthcare delivery context and examines relevant mediating variables. We consider key characteristics of: (i) interdependence in healthcare delivery processes, (ii) physician autonomy, and (iii) the trend of hospital employment of physicians, and draw on theoretical perspectives in coordination, shared values, and agency to explain how the use of EMR can improve physicians’ performance. In order to examine the effects of physician employment on work practices in the hospital, we collected 583 data points from 302 hospitals in 47 states in the USA to test two models: one for employed and another for nonemployed physicians. Results show that information sharing and shared values among healthcare delivery professionals fully mediate the relationship between EMR use and physicians’ performance. Next, physician employment determines which mediating variable constitutes the pathway from EMR use to physicians’ performance. Finally, we highlight the impact of shared values between the hospital and physicians in enhancing information sharing and physicians’ performance, extending studies of these behaviors among network partners in industrial settings. Overall, our study shows that EMR use should be complemented by processual (information sharing), social (shared values), and structural (physician employment) mechanisms to yield positive effects on physicians’ performance.     

Trans-ideological business values in international codes of conduct

Traditionally, scholars of international business have been unconcerned with ethics and values, in part due to the widely-held belief that standards vary across cultures and ideologies. Recently, however, business ethicists have considered whether there are some business-related values that are shared across cultures. Through an analysis of the codes of conduct for multinational enterprises of four international organizations, five trans-ideological business values are discovered. They are national sovereignty, social equity, human rights, market integrity and organizational autonomy. The consensus in values is critically important for both scholarship and management.An earlier version of this paper was presented at the Second Annual Meeting of the International Association of Business and Society (March 1991). The author would like to thank three anonymous reviewers for their helpful comments on earlier drafts.     

A Contingent Claims Model of Corporate Pension Obligations*

This study develops a contingent claims model for valuing the implicit market value of the pension claim associated with defined benefit pension plans. In this model, the firm issues pension, debt, and equity claims. These claims have joint access to two underlying portfolios: corporate and pension. The changes in the market values of these two portfolios are assumed to follow a joint lognormal diffusion process. By imposing terminal boundary conditions implied by Employment Retirement Income Security Act (ERISA) rules and the pension insurance provisions of the Pension Benefit Guaranty Corporation (PBGC) on the partial differential equation, a solution for the pension value is obtained. This quasi-market measure of the value of the pension claim may be represented by a portfolio consisting of four components: (1) a risk-free discount bond with face value equal to promised pension benefits; (2) a short put on pension assets with exercise price equal to pension benefits; (3) a long call on 30 percent of corporate assets with exercise price equal to the face value of secured corporate debt; and (4) a short call on 30 percent of corporate assets with a stochastic exercise price which depends on the terminal value of the pension fund. A numerical example using 1992 and 1993 financial statement data from six major U.S. corporations is provided. This example illustrates the usefulness of the model's prediction and the potential effect of theoretical pension values on corporate debt-equity ratios.     

Price Inference in Small Markets

This paper investigates the effects of market size on the ability of price to aggregate traders' private information. To account for heterogeneity in correlation of trader values, a Gaussian model of double auction is introduced that departs from the standard information structure based on a common (fundamental) shock. The paper shows that markets are informationally efficient only if correlations of values coincide across all bidder pairs. As a result, with heterogeneously interdependent values, price informativeness may not increase monotonically with market size. As a necessary and sufficient condition for the monotonicity, price informativeness increases with the number of traders if the implied reduction in (the absolute value of) an average correlation statistic of an information structure is sufficiently small.     

The Stewardship of the Temporal Commons

The contemporary move toward privatization has led to the assigning of property rights to many intangible public resources. One shared intangible resource swept up in this marketization is, we argue, the temporal commons – the shared conceptualization of time and temporal values created by a culture-carrying collectivity. As a result, the stewardship, or management, of the temporal commons is judged exclusively by the market-sanctioned metric of efficiency. We suggest that metrics based on the stakeholder approach to organizational effectiveness are more appropriate than the sole reliance on market efficiency criteria for judging the stewardship of a temporal commons, and offer several examples of stewardship evaluated by such metrics from the perspectives of a variety of stakeholders. We close with a call for more cognizant agency and wider participation in temporal commons stewardship.     

Shared Ownership and Affordable Housing: A Political Solution in Search of a Planning Justification?

Planners in England routinely include shared ownership (SO) housing in the affordable housing element of new developments. Government policies in a number of European countries have also backed intermediate housing market mechanisms as a solution to housing affordability. The rhetoric of such mechanisms makes claims about its social progressiveness, its role in facilitating socio-economic mobility and helping people move from rented accommodation into full owner-occupation. SO schemes in England have been justified on the grounds of being transitional tenures and planners have accepted SO on this basis. However, given the paucity of rigorous empirical work, there is a concern that this is a policy based on assumption rather than evidence. This paper delineates existing knowledge, clarifies dimensions of the intermediate housing market and highlights underlying policy issues based on a large data-set of shared owners in England. Our analysis indicates that SO may not be appropriately classified as affordable housing, and justifiable policy requires further evidence.     

现货价格和需求关联时期权组合合约模式下采购风险管理策略

在现货价格和客户端需求关联的情形下,本文引用期权组合合约建立现货市场供应量有限时的两阶段采购风险管理模型,以期最大化零售商的期望收益。文中先用逆向归纳法列出零售商第二阶段的最优策略,采用标准扰动定理得出有效合约应满足的最优性条件,并将原模型转化为单调的最短路径问题,应用动态规划求解最优的采购策略。最后用算例分析了现货价格与需求的相关系数及现货市场的供应量对最优策略的影响,发现当供应量一定时,各有效合约的最优预订量及有效合约的总预订量都随着相关系数的增大而提高,并且有效合约受相关系数的影响大小取决于合约的灵活性;并且,当相关系数一定时,有效合约的总预订量及执行价格最低的有效合约的最优预订量都随着供应量的增加而单调减少。     

基于或有可转债的债务悬空应对方法及其定价研究

债务悬空(Debt Overhang)会导致公司陷入财务困境,阻滞其开展正常的投融资活动。现有研究表明,发行或有可转债(Contingent Convertible Bonds,简称CoCos)有望成为一种应对债务悬空的有效方法。本文以债务悬空应对方法及其定价为研究主题,通过改进CoCos债转股的触发阈值,即以债务悬空发生时公司资产账面价值作为触发阈值,以解决现有CoCos产品在债务悬空应对的适配性方面的不足。具体地,结合债务悬空发生时公司资本结构的特征,考虑转股后的破产清算,基于结构化信用衍生品定价方法进行建模,进而得到CoCos债转股及破产清算时公司资产账面价值的触发阈值,并给出了公司资产、普通债、CoCos、股权价值的解析解,据此进一步计算CoCos和普通债的信用价差及公司的财务杠杆。最后,通过数值模拟,探析了波动率、发行期限以及息票支付的税盾效应对CoCos和普通债信用价差的影响,及CoCos和普通债的发行期限和数量对财务杠杆的影响;得到了通过适当提高CoCos合约的债转股比例,可以有效降低债务悬空发生可能性的结论。     

Strategic Preparedness for Recovery from Catastrophic Risks to Communities and Infrastructure Systems of Systems

Natural and human‐induced disasters affect organizations in myriad ways because of the inherent interconnectedness and interdependencies among human, cyber, and physical infrastructures, but more importantly, because organizations depend on the effectiveness of people and on the leadership they provide to the organizations they serve and represent. These human–organizational–cyber–physical infrastructure entities are termed systems of systems. Given the multiple perspectives that characterize them, they cannot be modeled effectively with a single model. The focus of this article is: (i) the centrality of the states of a system in modeling; (ii) the efficacious role of shared states in modeling systems of systems, in identification, and in the meta‐modeling of systems of systems; and (iii) the contributions of the above to strategic preparedness, response to, and recovery from catastrophic risk to such systems. Strategic preparedness connotes a decision‐making process and its associated actions. These must be: implemented in advance of a natural or human‐induced disaster, aimed at reducing consequences (e.g., recovery time, community suffering, and cost), and/or controlling their likelihood to a level considered acceptable (through the decisionmakers’ implicit and explicit acceptance of various risks and tradeoffs). The inoperability input‐output model (IIM), which is grounded on Leontief's input/output model, has enabled the modeling of interdependent subsystems. Two separate modeling structures are introduced. These are: phantom system models (PSM), where shared states constitute the essence of modeling coupled systems; and the IIM, where interdependencies among sectors of the economy are manifested by the Leontief matrix of technological coefficients. This article demonstrates the potential contributions of these two models to each other, and thus to more informative modeling of systems of systems schema. The contributions of shared states to this modeling and to systems identification are presented with case studies.     

网络借贷市场参与主体行为策略的演化博弈均衡分析——基于三方博弈的视角

由于监管缺失、信用风险管理缺位,导致网络借贷市场的违约事件持续出现,损害网络借贷市场的参与者利益。本文构建了一个包括网络借贷平台、金融监管机构和投资者的网络借贷市场参与主体的三方行为策略演化博弈模型,从演化博弈的角度分析了网络借贷平台、金融监管机构和投资者的策略选择对网络借贷市场运行的影响,并以拍拍贷平台为案例进行数值模拟分析。研究结果表明：不同初始值的三方博弈结果存在显著差异,网络借贷市场参与主体行为策略的演化博弈不具有稳定中心点、且不存在稳定的均衡点。另外,当金融监管机构采取"严格监管"措施时,惩罚值越高,网络借贷平台越倾向于选择"自律"的行为策略,随着投资者投资额度的增加,网络借贷平台选择"自律"行为策略的概率逐渐降低。最后,提出规范网络借贷市场参与者行为和风险控制的对策建议。     

Financial Market Globalization,Symmetry‐Breaking,and Endogenous Inequality of Nations

This paper investigates the effects of financial market globalization on the inequality of nations. The world economy consists of inherently identical countries, which differ only in their levels of capital stock. Each country is represented by the standard overlapping generations model, modified only to incorporate credit market imperfection. An integration of financial markets affects the set of stable steady states, as it changes the balance between the equalizing force of the diminishing returns technology and the unequalizing force of the wealth‐dependent borrowing constraint. The model is tractable enough to allow for a complete characterization of the stable steady states. In the absence of the international financial market, the world economy has a unique steady state, which is symmetric and stable. In the presence of the international financial market, symmetry‐breaking occurs under some conditions. That is, the symmetric steady state loses its stability and stable asymmetric steady states come to exist. In the stable asymmetric steady states, the world economy is endogenously divided into the rich and poor countries; the borrowing constraints are binding in the poor but not in the rich; the world output is smaller, the rich are richer and the poor are poorer in any of the stable asymmetric steady states than in the (unstable) symmetric steady state.     

A Saul Alinsky primer for the 21st century: The roles of cultural competence and cultural brokerage in fostering mobilization in support of change

How can a proponent of change mobilize groups and organizations in support of a common project? Building on an extensive review of social movement theorizing and action, we argue that shared interests, network connections, the availability of resources, and the emergence of political, market and corporate opportunities (the standard topics discussed in extant literature) may be necessary, but are often insufficient for spurring mobilization. Conversely, cultural factors such as frames, identities, or practices are essential. Their presence can facilitate coordinated action even among unlikely allies, and their absence can prevent such action. Inspired by the work of Saul Alinsky (1909–1972), along with contemporary illustrations, we construct a two-step model of the role of culture in mobilizing for change. We bring attention to a change proponent’s cultural competence – skill in appreciating the different cultural meanings and values of those involved in a particular project of change – and cultural brokerage – skill in bridging and negotiating among actors with different cultural repertoires, to reach a temporary truce or covenant. We focus on two types of activities that define cultural brokerage, integration and redefinition, and apply them to the cultural factors of frames, identities, and/or practices. Our paper contributes to contemporary research on social movements, institutional theory, and cultural sociology.     

A cross-cultural investigation of the shared values relationship

Data from managers in Australia (N=505) and Hong Kong (N=653) support the findings of studies using American managers and their companies that shared values, or person-organization values fit, is strongly related to positive work attitudes. This relationship is unaffected by culture, as two-way analysis of variance reveals no interaction effect between shared values and country. Managerial implications are discussed.     

Research and development project selection and resource allocation: a review of quantitative modelling approaches

This paper reviews the literature on quantitative modelling for research and development (R&;D) project selection and resource allocation. The topic has been a subject of operations research for about four decades. Its importance stems from the fact that R&D projects are a core element of corporate renewal, heavily influence a firm's market success and, if not properly chosen and trimmed, may waste large amounts of resources or even ruin the enterprise. Our survey classifies and characterizes the various modelling approaches.     

Long-Term Effects of a Plant Closure: a Multistate Duration Analysis of Event History Data in a Ten-Year Follow-Up Study

This paper discusses the possible effects on future prospects in the labour market of those who suffer a plant closure. A multistate duration model is estimated on monthly event data comprising 172 individuals over ten years, with the occurrence of the plant closure among the regressors. An individual can escape to one of several destinations when exiting one of three origin states (unemployed, sick leave, outside the labour force). Our prime concern has been transitions leading to a new job or to destination states outside the labour force (disability pension and at home, without any social security benefit). We find indications of severe negative long-term effects on employment from a plant closure: long durations in unemployment when searching for new jobs, higher incidence of leaving the labour force, longer periods of sick leave and higher incidence of disability pension. Thus, an adverse shock reducing employment may have negative long-term effects on the labour market through long spells of unemployment and a shrinking labour force. Our findings thus support the hypothesis of hysteresis dynamics in the labour market.     

WHY MERGERS REDUCE PROFITS AND RAISE SHARE PRICES–A THEORY OF PREEMPTIVE MERGERS

We provide a possible explanation for the empirical puzzle that mergers often reduce profits, but raise share prices. If being an “insider” is better than being an “outsider”, firms may merge to preempt their partner merging with a rival. The insiders' stock market value is increased, since the risk of becoming an outsider is eliminated. These results are derived in an endogenous‐merger model, predicting the conditions under which mergers occur, when they occur, and how the surplus is shared. (JEL: L13, L41, G34, C78)     

A Corporate Culture Pattern to Manage Business Ethics

Within the general frame of proposals for an adequate management of business ethics, this paper is based on the vision of corporate culture as a pattern to achieve such purpose. If we consider ethics as a specific value of corporate culture, we may resort to the mechanism of cultural change and implementation in order to manage ethics. Despite the difficulties it entails in terms of time and money investment, this procedure is one of the safest ways to reach ethical values which are known, shared and then practiced by all the members of a corporation, whatever the category. From this central standpoint, and basing ourselves on our own proposal for the management of culture, we shall describe which specific steps must be taken in order to achieve a set of ethical values which are both realistic and furthermore shared by all collaborators of an organization. This revised version was published online in July 2006 with corrections to the Cover Date.     

Risk Modeling of Interdependent Complex Systems of Systems: Theory and Practice

The emergence of the complexity characterizing our systems of systems (SoS) requires a reevaluation of the way we model, assess, manage, communicate, and analyze the risk thereto. Current models for risk analysis of emergent complex SoS are insufficient because too often they rely on the same risk functions and models used for single systems. These models commonly fail to incorporate the complexity derived from the networks of interdependencies and interconnectedness (I–I) characterizing SoS. There is a need to reevaluate currently practiced risk analysis to respond to this reality by examining, and thus comprehending, what makes emergent SoS complex. The key to evaluating the risk to SoS lies in understanding the genesis of characterizing I–I of systems manifested through shared states and other essential entities within and among the systems that constitute SoS. The term “essential entities” includes shared decisions, resources, functions, policies, decisionmakers, stakeholders, organizational setups, and others. This undertaking can be accomplished by building on state‐space theory, which is fundamental to systems engineering and process control. This article presents a theoretical and analytical framework for modeling the risk to SoS with two case studies performed with the MITRE Corporation and demonstrates the pivotal contributions made by shared states and other essential entities to modeling and analysis of the risk to complex SoS. A third case study highlights the multifarious representations of SoS, which require harmonizing the risk analysis process currently applied to single systems when applied to complex SoS.
