Broken Effects? How to Reduce False Positives in Panel Regressions 破碎的影响?如何减少面板回归的误报
Q2 MANAGEMENT Pub Date : 2023-03-01 DOI: 10.1287/stsc.2022.0172

Many published papers in the management field have used statistical methods that, according to the latest insights in econometrics, can lead to elevated rates of false positives: results that appear “significant,” whereas they are not. The question is how problematic these less robust econometric analyses are in practice for management research. This paper presents simulations and an empirical replication to investigate two widespread but now largely discredited practices in panel data analysis: nonclustered standard errors and random effects (RE). The simulations indicate that these two practices can lead to strongly elevated rates of false positives in typical empirical settings studied in management research. The often-advocated Hausman test does not always prevent false positives in RE regressions. Replication of a published regression that used RE and classic standard errors yields that many of the coefficients reported as significant in the original analysis become insignificant when using fixed effects and clustered standard errors, on a slightly different sample. Based on the findings in this paper, published results using nonclustered standard errors or RE estimates for panel data should be interpreted with great care, because the probability that they are false positives can be much larger than reported. Going forward, empirical researchers should cluster standard errors to account for serial correlation and use fixed rather than random effects to account for unobserved heterogeneity. Funding: X.

根据计量经济学的最新见解,管理领域的许多已发表论文都使用了统计方法,这些方法可能导致误报率升高:结果看起来“显著”,但实际上并非如此。问题是,在管理研究的实践中,这些不那么稳健的计量经济学分析有多大问题。本文提出了模拟和经验复制,以调查面板数据分析中两种广泛但现在基本上不可信的做法:非聚类标准误差和随机效应(RE)。模拟表明,在管理研究中研究的典型经验设置中,这两种做法可能导致误报率大幅上升。经常提倡的Hausman检验并不总能防止RE回归中的假阳性。使用正则化和经典标准误差的已发表回归的复制结果表明,当在稍微不同的样本上使用固定效应和聚类标准误差时,许多在原始分析中报告为显著的系数变得不显著。根据本文的发现,使用非聚类标准误差或对面板数据进行RE估计的已发表结果应该非常小心地解释,因为它们是假阳性的概率可能比报告的要大得多。展望未来,实证研究人员应该聚类标准误差来解释序列相关性,并使用固定效应而不是随机效应来解释未观察到的异质性。基金资助:李x获得Ian Potter ' 93D博士奖资助。补充材料:在线附录可在https://doi.org/10.1287/stsc.2022.0172上获得。

The New Stakeholder Theory on Organizational Purpose 关于组织目的的新利益相关者理论
IF 3.9 Q2 MANAGEMENT Pub Date : 2023-02-27 DOI: 10.1287/stsc.2023.0184
A. McGahan
The new stakeholder theory (NST) grapples with two canonical questions: Which stakeholders are enfranchised in organizations? How is the value created through stakeholder collaboration distributed and experienced by stakeholders? This paper first describes how the NST builds on original stakeholder theory to ask these two specific questions. The defining features of the NST are (i) a broad range of dependent variables, (ii) descriptiveness, (iii) formalized analysis, (iv) boundaries on stakeholder enfranchisement, and (v) analytic links to other established theories. The paper then assesses the assumptions and implications of this theory for understanding organizational purpose. A primary idea is that the NST conceptualizes purpose as originating in the goals, needs, and interests of stakeholders as complex, nuanced actors. Under the NST, the organization is conceived of as a tool—a functionalized construction—through which enfranchised stakeholders pursue a shared purpose that leads to experiences of stakeholder value in terms that are defined by the relevant stakeholders themselves. The survival and profitability of an organization depends on its effectiveness and efficiency as a tool for accomplishing mutual stakeholder aims, which are what define organizational purpose.

新利益相关者理论(NST)努力解决两个典型问题:哪些利益相关者在组织中被授权?利益相关者如何分配和体验利益相关者协作所创造的价值?本文首先描述了NST如何在原始利益相关者理论的基础上提出这两个具体问题。NST的定义特征是(i)广泛的因变量,(ii)描述性,(iii)形式化分析,(iv)利益相关者授权的边界,以及(v)与其他既定理论的分析联系。然后,本文评估了该理论的假设和含义,以理解组织目的。一个主要的想法是,NST将目的概念化为源于利益相关者的目标、需求和利益,这些利益相关者是复杂的、微妙的参与者。在NST下,组织被视为一种工具——一种功能化的结构——通过它,被授权的利益相关者追求一个共同的目标,从而获得利益相关者自己定义的利益相关者价值体验。一个组织的生存和盈利能力取决于其作为实现共同利益相关者目标的工具的有效性和效率,这些目标定义了组织的目的。资助:由加拿大社会科学与研究理事会资助。

Seeing Beyond the Here and Now: How Corporate Purpose Combats Corporate Myopia 超越此时此地:企业目标如何对抗企业短视

Corporations are currently confronting major, interlocking crises, including climate change, biodiversity loss, inequalities, and social isolation. When under threat, executives tend to focus inward and on the short term. This is particularly unfortunate because it is in such crises that executives need to see beyond the here and now in order to ride the storms. In this paper, we argue that corporate purpose helps organizations fight such myopia and offer four mechanisms through which this works: exposing new insights, seeing issues holistically, helping to sustain focus, and bringing unity and direction. Funding: The authors acknowledge the generous funding from the Social Sciences and Humanities Council of Canada [Grant 895-2015-0026] that contributed to the broader project in which these ideas were generated.
企业目前正面临着环环相扣的重大危机,包括气候变化、生物多样性丧失、不平等和社会孤立。当面临威胁时,高管们倾向于关注内部和短期。这尤其令人遗憾,因为正是在这样的危机中,高管们需要把眼光放得更远,才能驾驭风暴。在本文中,我们认为企业目标可以帮助组织对抗这种短视现象,并提供了四种机制,通过这些机制:揭示新的见解,全面地看待问题,帮助保持焦点,以及带来团结和方向。资助:作者感谢加拿大社会科学与人文理事会的慷慨资助[Grant 895-2015-0026],为产生这些想法的更广泛的项目做出了贡献。

Inside-out and Outside-in Perspectives on Corporate Purpose 企业宗旨的内外观
IF 3.9 Q2 MANAGEMENT Pub Date : 2023-02-10 DOI: 10.1287/stsc.2023.0180
J. Almandoz
Corporate purpose is receiving an extraordinary amount of attention from both scholars and practitioners. But do existing theories of management help us to understand this unexpected development? This study represents an effort to understand purpose better. I characterize inside-out and outside-in perspectives on purpose as distinct but connected phenomena related to different research traditions. Inside-out purpose is a channeling of the passion and commitment employees feel toward fulfilling stakeholder needs; outside-in purpose is society and external stakeholders urgently calling on the organization to live up to its responsibilities. I devote special attention to theories that best explain the present moment’s unique awareness of corporate purpose. Among them is the work of Philip Selznick, emphasizing values, and the literature on the new institutionalism and institutional logics. I conclude with a section on how leaders can leverage the benefits of both perspectives while mitigating their risks. I also make recommendations for future research. History: This paper has been accepted for the Strategy Science Special Issue on Corporate Purpose. Funding: This work benefited from funding from the Social Trends Institute and the Juan Antonio Perez Lopez Chair at IESE Business School.
企业目标正受到学者和实践者的极大关注。但是,现有的管理理论能帮助我们理解这一意想不到的发展吗?这项研究代表了更好地理解目的的努力。我将目的的由内而外和由外而内的观点描述为与不同研究传统相关的不同但相互关联的现象。由内而外的目标是引导员工对满足利益相关者需求的热情和承诺;由外而内的目的是社会和外部利益相关者迫切要求组织履行其责任。我特别关注那些最能解释当下企业目标独特意识的理论。其中有强调价值观的菲利普·塞尔兹尼克的著作,以及关于新制度主义和制度逻辑的文献。最后,我用一节来总结领导者如何在降低风险的同时利用这两种观点的好处。我还对未来的研究提出了建议。历史:本文已被《战略科学》公司宗旨特刊接受。资助:这项工作得益于社会趋势研究所和IESE商学院胡安·安东尼奥·佩雷斯·洛佩兹主席的资助。

Shared Identity Schemas Shape Incumbent Responses to New Entrants 共享身份图式塑造了在位者对新进入者的反应
IF 3.9 Q2 MANAGEMENT Pub Date : 2022-12-15 DOI: 10.1287/stsc.2022.0179
Özgecan Koçak, Başak Topaler
An outstanding question in research on competitive strategy is what determines the strength and type of strategic response that incumbents deploy against new entrants. We argue that strategists’ assessment of threat from new entrants and their choice of strategic reactions depend on the shared identity schema in their field. Position of new entrants across identity categories indicate whether they pose a competitive threat within the same identity-based niche or outside it and whether they threaten to erode the incumbent’s category’s social value relative to other categories. Potential reactions to these threats can also be classified according to whether they protect or enhance the value that incumbents create and capture through their membership in their identity category. Matching identity-relevant strategic actions to the type of threat that new entries pose, we argue that incumbents (1) employ identity-deepening tactics in response to competition in their identity-based niche; (2) use identity-extending tactics in response to competition outside their niche; (3) respond to categorical identity threats by affirming their identities; and (4) are less likely to respond to either competitive or identity threats that originate from new entrants that do not clearly fit in the shared identity schema. We find support for our predictions in analyses using data on the population of Turkish universities over a 30-year period. We discuss theoretical implications for ecological and socio-cognitive studies of markets and practical implications for predicting patterns of strategic interaction and disruptive potential of new entrants.

竞争战略研究中的一个突出问题是,什么决定了现有企业对新进入者采取的战略反应的强度和类型。我们认为,战略家对新进入者威胁的评估及其战略反应的选择取决于他们所在领域的共同身份图式。新进入者在身份类别中的位置表明他们是否在同一身份基础上的利基内或外部构成竞争威胁,以及他们是否有可能侵蚀现有类别相对于其他类别的社会价值。对这些威胁的潜在反应也可以根据它们是否保护或提高现有企业通过其身份类别的成员身份创造和获取的价值来进行分类。将与身份相关的战略行动与新进入者构成的威胁类型相匹配,我们认为现有企业(1)采用身份深化策略来应对其基于身份的利基中的竞争;(2)利用身份延伸策略应对利基市场以外的竞争;(3)对类别认同威胁的回应是肯定其身份;(4)不太可能对来自不符合共享身份模式的新进入者的竞争或身份威胁做出反应。我们发现支持我们的预测在分析中使用数据的土耳其大学的人口在30年期间。我们讨论了市场生态和社会认知研究的理论意义,以及预测战略互动模式和新进入者破坏性潜力的实际意义。补充材料:电子伴侣可在https://doi.org/10.1287/stsc.2022.0179上获得。

Don’t Look Back? Backward Compatibility in the Video Gaming Industry 不要回头看?视频游戏行业的向后兼容性
IF 3.9 Q2 MANAGEMENT Pub Date : 2022-11-23 DOI: 10.1287/stsc.2022.0177

Backward compatibility is a governance strategy that can be adopted by platform owners to build indirect network effects and encourage owners of older compatible software to update to newer hardware models. Previous research shows backward compatibility has a positive effect on hardware sales. However, there is limited evidence concerning the other associated costs and benefits. In particular, there is a lack of evidence on the effect of backward compatibility on software sales despite its importance in understanding the full range of possible network and sales displacement effects associated with the strategy. Using weekly software-level sales data from the U.S. video gaming industry, we find that backward-compatible hardware associates with increased sales of software released for the previous hardware generation. However, we find that the introduction of backward compatibility may not increase the sales of new hardware if the feature is not available immediately at launch. Further, we show that the increased sales of software for the old hardware platform may cannibalize software sales for the new platform. Overall, our results suggest that backward compatibility is time-sensitive and involves several important trade-offs. We, therefore, conclude that the use of backward compatibility needs to be carefully considered by platform owners prior to implementation.
向后兼容性是一种治理策略,平台所有者可以采用它来构建间接网络效应,并鼓励旧兼容软件的所有者更新到较新的硬件模型。之前的研究表明,向后兼容性对硬件销售有积极影响。然而,关于其他相关成本和收益的证据有限。特别是,缺乏证据表明向后兼容性对软件销售的影响,尽管它对于理解与该策略相关的所有可能的网络和销售位移效应很重要。通过使用来自美国电子游戏行业的每周软件级销售数据,我们发现向后兼容的硬件与上一代硬件发布的软件销售增长有关。然而,我们发现,如果向后兼容功能不能在发布时立即可用,则引入向后兼容性可能不会增加新硬件的销售。此外,我们还表明,旧硬件平台的软件销售增长可能会蚕食新平台的软件销售。总的来说,我们的结果表明向后兼容性是时间敏感的,并且涉及几个重要的权衡。因此,我们得出结论,平台所有者需要在实现之前仔细考虑向后兼容性的使用。

Move-in Ready or Fixer-Upper? VC Specialization and Start-up Innovation 准备入住还是待修?风险投资专业化与创业创新
IF 3.9 Q2 MANAGEMENT Pub Date : 2022-10-26 DOI: 10.1287/stsc.2022.0176
Elisa Alvarez-Garrido
Extant scholarship typically assumes that VC firms prefer to pick winners. I offer an alternative perspective: that specialist VC firms can select less attractive start-ups—with innovative potential but in need of help—and then contribute to the start-ups’ innovative processes so they can achieve their potential. The analogy is buying a fixer-upper house, which, with the right help, can be brought to the level of one that is move-in ready. I argue that specialist (versus generalist) VC firms in the syndicate have superior commercialization knowledge and specialized resource networks, and they can choose to follow a move-in-ready strategy (select winners) or a fixer-upper strategy (build winners). This choice is contingent on the research environment and how unique the help from the specialist VC firm is: in well-developed research environments, a specialist adds less value and may follow a move-in-ready strategy; in less-developed research environments, a specialist adds more value and may follow a fixer-upper strategy. I leverage an ideal empirical context, global biotechnology VC-backed start-ups, over the period 1996–2006, when the biotech industry was established in the United States and developing in 25 other countries, and highlight qualitative insights from 20 interviews with investors in seven countries.
Extent奖学金通常假设风险投资公司更喜欢挑选赢家。我提供了另一种视角:专业的风险投资公司可以选择吸引力较小的初创企业——具有创新潜力但需要帮助——然后为初创企业的创新过程做出贡献,使其能够发挥潜力。这个比喻是买一栋装修好的上层住宅,在正确的帮助下,它可以达到准备入住的水平。我认为,辛迪加中的专业(相对于多面手)风险投资公司拥有卓越的商业化知识和专业的资源网络,他们可以选择采用现成的战略(选择赢家)或固定的上层战略(建立赢家)。这一选择取决于研究环境以及专业风险投资公司的帮助有多独特:在发达的研究环境中,专家增加的价值较少,可能会遵循现成的策略;在不太发达的研究环境中,专家会增加更多的价值,并可能遵循更高的策略。我利用了一个理想的经验背景,即1996-2006年期间全球生物技术风险投资支持的初创企业,当时生物技术行业在美国成立,并在其他25个国家发展,并强调了对7个国家投资者的20次采访中的质量见解。

This choice is contingent on the research environment and how unique the help from the specialist VC firm is: in well-developed research environments, a specialist adds less value and may follow a move-in-ready strategy; in less-developed research environments, a specialist adds more value and may follow a fixer-upper strategy. I leverage an ideal empirical context, global biotechnology VC-backed start-ups, over the period 1996–2006, when the biotech industry was established in the United States and developing in 25 other countries, and highlight qualitative insights from 20 interviews with investors in seven countries.","PeriodicalId":45295,"journal":{"name":"Strategy Science","volume":" ","pages":""},"PeriodicalIF":3.9,"publicationDate":"2022-10-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44668793","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

An important consequence of an alliance is that partnering firms combine their reputations by associating them to jointly implemented projects. However, an often-overlooked aspect is that those reputations may themselves change due to both the announcement of the firms’ decision to form the alliance and the performance of joint projects. We develop a formal model that provides an integrated perspective of these reputational effects, while allowing us to isolate and characterize each of them. We find that the way in which the firms’ competence levels affect their decision to form an alliance determines how the firms’ reputations evolve following the announcement of the alliance and the performance of joint projects. This indicates that the analysis of the reputational effects of an alliance requires understanding the firms’ alliance formation decision in the first place. We show, for instance, that a firm’s reputation may decrease following the decision to form an alliance, and that the impact of project performance on the reputations of alliance partners can be very asymmetric. Among other things, our analysis implies that a firm’s desirability as an alliance partner does not necessarily increase with its reputation and level of competence.
联盟的一个重要结果是,合作公司通过联合实施项目来联合他们的声誉。然而,一个经常被忽视的方面是,这些声誉本身可能会因为公司决定组建联盟的公告和联合项目的表现而改变。我们开发了一个正式的模型,提供了这些声誉效应的综合视角,同时允许我们分离和表征它们中的每一个。我们发现,企业能力水平影响其联盟决策的方式决定了企业在联盟宣布后的声誉演变和联合项目的绩效。这表明,对联盟声誉效应的分析首先需要了解企业的联盟形成决策。例如,我们表明,公司的声誉可能会在决定组建联盟后下降,项目绩效对联盟伙伴声誉的影响可能非常不对称。除其他外,我们的分析表明,企业作为联盟伙伴的可取性并不一定随着其声誉和能力水平的提高而增加。

Population-Level Evidence of the Gender Gap in Technology Entrepreneurship 技术创业中性别差距的人口层面证据

This study investigates the gender gap in entrepreneurship in the technology industry. Digitization has created vast economic opportunities in the technology sector and has lowered many barriers to entry, thus reducing traditional frictions regarding entrepreneurship and potentially increasing opportunities for female founders. However, anecdotal evidence has suggested that female technology founders are rare and that women are underrepresented in science, technology, engineering, and mathematics roles. Based on individual career histories collected from more than 42 million U.S.-based LinkedIn profiles, including more than 1.3 million founders, we explore whether there are higher rates of female founders in technology companies relative to other industries. Our analysis revealed the following: (1) Females were only half as likely as males to found businesses in the technology industry. (2) Females were less likely to found successive businesses (i.e., serial founders), which was even more pronounced in the technology industry. (3) When we used the gender gap in labor force participation as a baseline, the gender gap in technology entrepreneurship was particularly large, even compared with other male-dominated industries (e.g., construction). (4) The gender gap in technology entrepreneurship was driven by lower rates of entrepreneurship by females in lower positions in the organizational hierarchy. In contrast, females who reached the C-suite in technology sectors were 16% more likely to found firms compared with their female C-suite counterparts in nontechnology industries. Combined, the results provide a nuanced view of the gender gap in entrepreneurship.
本研究调查了科技行业创业中的性别差距。数字化为科技行业创造了巨大的经济机会,降低了许多进入壁垒,从而减少了创业方面的传统摩擦,并可能增加女性创始人的机会。然而,轶事证据表明,女性技术创始人很少,女性在科学、技术、工程和数学领域的代表性不足。根据从4200多万美国领英个人资料中收集的个人职业史,包括130多万创始人,我们探讨了科技公司中女性创始人的比例是否高于其他行业。我们的分析显示:(1)女性在科技行业创业的可能性只有男性的一半。(2) 女性不太可能找到连续的企业(即连续创始人),这在科技行业更为明显。(3) 当我们将劳动力参与的性别差距作为基线时,即使与其他男性主导的行业(如建筑业)相比,技术创业的性别差距也特别大。(4) 技术创业中的性别差距是由组织层级中职位较低的女性创业率较低造成的。相比之下,与非技术行业的女性高管相比,在技术行业进入高管层的女性找到公司的可能性高出16%。综合起来,研究结果对创业中的性别差距提供了一个细致入微的视角。
