A note on the projection properties of Hadamard matrices obtained by the first Payley construction

We show that the projections on four factors of an arbitrary orthogonal array of strength 2 allow the estimation of main effects and two-factor interactions when all other effects are assumed to be zero, if those projections satisfy the bounds given by Weils theorem. The only exceptions are the Hadamard matrices of orders 16 and 24. A consequence is again the estimability of main effects and two-factor interactions for the projections on four factors of the first Payley construction for arbitrary run size.     

Entry in the presence of dueling options

This paper investigates the influence of industry uncertainty on the decision by established firms to enter a new industry. Specifically, we examine the tension between the option to defer , which discourages entry in the presence of uncertainty, and the option to grow , which may encourage entry in the presence of uncertainty when there are early mover advantages. Empirical analysis on data from a broad array of industries revealed that the effect of uncertainty on entry is not monotonic. Our findings are the first to find support for the nonmonotonic effect of uncertainty that has only recently emerged in theoretical treatments of real options theory, and amplify the importance of considering both the option to defer and the option to grow when contemplating entry. Furthermore, we found evidence that the relationship between uncertainty and entry is moderated by: (a) irreversibility, which influences the value of the option to defer; (b) the total value of growth opportunities; and (c) early mover advantages, which magnify the value of growth options.

Spatial takeoff in the first industrial revolution

Using the framework of Desmet and Rossi-Hansberg (forthcoming), we present a model of spatial takeoff that is calibrated using spatially-disaggregated occupational data for England in c. 1710. The model predicts changes in the spatial distribution of agricultural and manufacturing employment which match data for c. 1817 and 1861. The model also matches a number of aggregate changes that characterise the first industrial revolution. Using counterfactual geographical distributions, we show that the initial concentration of productivity can matter for whether and when an industrial takeoff occurs. Subsidies to innovation in either sector can bring forward the date of takeoff while subsidies to the use of land by manufacturing firms can significantly delay a takeoff because it decreases spatial concentration of activity.     

组织隐性知识转移的演化博弈——基于互惠性企业环境

知识转移是知识管理的重要内容,隐性知识转移是提高组织知识管理效率的有效手段。互惠性企业环境为隐性知识转移的实现提供了有效的手段,从而克服了隐性知识转移过程中的诸多障碍。互惠性偏好环境下个体间隐性知识的转移效率要显著高于理性经济环境下的知识转移效率,改善了知识转移主体的利益支付,同时也为互惠性企业环境下组织隐性知识转移的演化博弈分析创造了条件。演化博弈分析的结果显示,在一定的外部机制的激励下,组织隐性知识转移主体的总体存在着向互惠型知识转移主体演化的倾向,从而使互惠型个体间隐性知识转移进入主导性的稳定状态,最终提高了组织隐性知识转移的效率。     

谈“创先争优”的结果与过程

先进和优秀是中国共产党人的特征和追求,其本质是创和争,核心点是争创的过程。结果只是节点,过程才是更重要;结果体现绩效,过程更彰显价值。创先争优的过程体现了组织者的号召力和人生境界,体现着组织文化。     

投资者关注与IPO异象——来自网络搜索量的经验证据

利用谷歌趋势提供的搜索量数据,本文构建了一个投资者关注的直接衡量指标,在此基础上,运用行为金融学里投资者关注的理论,系统解释了IPO市场存在的三种异象。与文献中常见的其他解释变量相比,本文发现IPO前个股网络搜索量对于市场热销程度、首日超额收益和长期表现有更好的解释力和预测力,它可以解释首日超额收益的23%,长期累积收益率的10%以上,结果均十分显著。研究结果表明,投资者关注对资产价格有直接的影响,2009年的新股发行体制改革对首日超额收益的降低起到了明显作用。     

检讨我国撤销权制度

撤销权制度是债权人保全自己债权的重要制度,但我国撤销权制度存在着法律规定不够细致,司法实践经验积累不够丰富,理论探讨不够深入等问题,影响了我国撤销权制度的进一步完善和在现实生活中发挥作用。故做此文,抛砖引玉,以期引起讨论之风。     

Product resource–capability complementarity,integration mechanisms,and first product advantage

The current study extends work on resource-based theory (RBT) by exploring resource—capability complementarity in a new context—that of new technology ventures' (NTVs) first product (FP) commercialization in India. This study examines the influence of marketing and technology resource–capability complementarity on FP positional advantages (differentiation and cost-efficiency) and their influence on first product performance (FPP). Furthermore, this study incorporates the influence of supplier integration (SI) mechanisms (in terms of knowledge sharing and co-commercialization) in the process of FP commercialization. The findings suggest that asset complementarities have a positive relation with FP positional advantages, in that both differentiation and cost-efficiency enhance an NTV's FPP, and that SI moderates the relationships between both marketing and technology R–C complementarity and FP positional advantages.     

Strategizing Environmental Policy and Compliance for Firm Economic Sustainability: Evidence from Taiwanese Electronics Firms

This study aims to examine whether the compliance of environmental policies can sustain firm economic performance, and whether a timing issue is relevant to firm economic sustainability in pursuit of eco‐friendly efforts. Offering models predominantly based on the institutional theory, this study tests hypotheses using data from 284 companies in the electronics sector in Taiwan during the period from 1997 to 2010. The findings reveal that the execution of environment policies mostly improves firm economic sustainability and some joint green efforts can even strengthen such sustainability; however, firms aiming to sustain their economic performance should not hasten to undertake eco‐friendly efforts, implying that first movers may not be guaranteed firm economic performance. Thus, managers should carefully strategize their green efforts to comply with environmental policies, and execute them in due course to prevent disadvantages, such as market uncertainty and complexity of green practices, while conquering organizational inertia.
