When a Coauthor Joins an Editorial Board 当共同作者加入编辑委员会时
Pub Date : 2021-05-13 DOI: 10.2139/ssrn.3847685
Lorenzo Ductor, B. Visser
Using novel and large-scale data at the individual level, we find that an author publishes more articles when a coauthor joins an editorial board, both in the "coauthor's'" journal and in other journals. This effect is larger, the less experienced the author is, and disappears quickly once the coauthor leaves the journal's board. Of the hypotheses that we consider to explain these patterns, the signalling hypothesis is a strong contender. It argues that the temporary increase in status of the coauthor improves the plight of the author as it improves the inference that editorial boards make about the author's underlying quality. Only the favoritism hypothesis can explain that, especially at journals with low board turnover, articles published during a coauthor's stint on the editorial board receive less citations than articles published during other years.
在个人层面上使用新颖的大规模数据,我们发现,当一名合著者加入编委会时,无论是在“合著者”的期刊上还是在其他期刊上,一名作者发表的文章都更多。这种影响越大,作者越缺乏经验,一旦合著者离开期刊董事会,这种影响就会迅速消失。在我们考虑解释这些模式的假说中,信号假说是一个强有力的竞争者。它认为,共同作者地位的暂时提高改善了作者的困境,因为它改善了编辑委员会对作者潜在素质的推断。只有偏袒假说可以解释,特别是在董事会更替率低的期刊上,合著者在编委会任职期间发表的文章比其他年份发表的文章得到的引用要少。

Children tend to inherit their parents’ social class through the types of jobs they get. However, digital technologies are now transforming the way labour markets work. Candidates are increasingly screened using algorithmic decision making. Skills are validated with online tests and customer feedback ratings. Workplace communications take place over digital media. Could these transformations be undermining the advantages that have accrued to workers with posh accents, family connections, and expensively acquired educational qualifications? We examine this question with survey data from the online (remote) platform economy, a labour market segment in which these digital transformations have progressed furthest (N = 983). The results reveal that online platform workers come largely from privileged class backgrounds. Class also influences (via education) what types of online occupations workers do, from professional services to data entry. However, class background has surprisingly little influence on job quality, which is instead shaped by individual digital metrics such as feedback ratings. These findings cannot be fully reconciled with theories of a shift towards meritocracy nor with theories of a persisting influence of class origins. Instead, labour market digitalization may be decoupling inherited occupation from job quality.
子女往往会通过他们所从事的工作类型来继承父母的社会阶层。然而,数字技术正在改变劳动力市场的运作方式。候选人越来越多地使用算法决策来筛选。通过在线测试和客户反馈评级验证技能。工作场所的交流是通过数字媒体进行的。这些转变是否正在削弱那些拥有优雅口音、家庭关系和昂贵学历的工人积累起来的优势?我们用来自在线(远程)平台经济的调查数据来研究这个问题,这是一个劳动力市场细分市场,其中这些数字化转型进展最快(N = 983)。结果显示,网络平台员工大多来自特权阶级背景。阶级也会(通过教育)影响员工从事的在线职业类型,从专业服务到数据输入。然而,令人惊讶的是,阶级背景对工作质量的影响微乎其微,相反,工作质量是由反馈评级等个人数字指标决定的。这些发现不能与向精英政治转变的理论完全一致,也不能与阶级起源持续影响的理论完全一致。相反,劳动力市场数字化可能会将继承的职业与工作质量脱钩。

A Model of Inter-organizational Network Formation 组织间网络形成模型
Pub Date : 2021-05-02 DOI: 10.2139/ssrn.3838255
S. Gaonkar, A. Mele
How do inter-organizational networks emerge? Accounting for interdependence among ties while studying tie formation is one of the key challenges in this area of research. We address this challenge using an equilibrium framework where firms' decisions to form links with other firms are modeled as a strategic game. In this game, firms weigh the costs and benefits of establishing a relationship with other firms and form ties if their net payoffs are positive. We characterize the equilibrium networks as exponential random graphs (ERGM), and we estimate the firms' payoffs using a Bayesian approach. To demonstrate the usefulness of our approach, we apply the framework to a co-investment network of venture capital firms in the medical device industry. The equilibrium framework allows researchers to draw economic interpretation from parameter estimates of the ERGM Model. We learn that firms rely on their joint partners (transitivity) and prefer to form ties with firms similar to themselves (homophily). These results hold after controlling for the interdependence among ties. Another, critical advantage of a structural approach is that it allows us to simulate the effects of economic shocks or policy counterfactuals. We test two such policy shocks, namely, firm entry and regulatory change. We show how new firms' entry or a regulatory shock of minimum capital requirements increase the co-investment network's density and clustering.
组织间网络是如何出现的?在研究纽带形成的同时考虑纽带之间的相互依存关系是这一研究领域的关键挑战之一。我们使用均衡框架来解决这一挑战,在均衡框架中,企业与其他企业建立联系的决策被建模为战略博弈。在这个博弈中,企业权衡与其他企业建立关系的成本和收益,如果它们的净收益为正,就会形成联系。我们将均衡网络描述为指数随机图(ERGM),并使用贝叶斯方法估计公司的收益。为了证明我们方法的有效性,我们将该框架应用于医疗器械行业风险投资公司的共同投资网络。均衡框架允许研究人员从ERGM模型的参数估计中得出经济解释。我们了解到,企业依赖他们的合作伙伴(及物性),并倾向于与与自己相似的企业建立联系(同质性)。在控制了关系之间的相互依赖之后,这些结果仍然成立。结构性方法的另一个关键优势是,它使我们能够模拟经济冲击或政策反事实的影响。我们测试了两种这样的政策冲击,即企业进入和监管变化。我们展示了新公司的进入或最低资本要求的监管冲击如何增加共同投资网络的密度和集群。

How To Convert Millennial Consumers to Brand Evangelists Through Social Media Micro-Influencers 如何通过社交媒体微影响者将千禧一代消费者转化为品牌传播者
Pub Date : 2021-04-27 DOI: 10.21511/IM.17(2).2021.03

Undoubtedly, in the modern age of digitalization, Millennials, who are considered digital natives, have become a massive target market for salespersons. Changes in the way Millennials think accompanied by an explosion of social media have led to an increased focus on social media influencer marketing in the company sector. To help establish a new marketing paradigm that accounts for these changes, this research aims to conceptualize and investigate the process of building consumer-brand relationships with Millennial consumers through social media micro-influencers. Findings based on structural equation modeling revealed that four core characteristics of social media micro-influencers (i.e., authenticity, the meaning of the influencer, specific content, and secret sharing) were a significant antecedent of brand engagement and brand love, which, in turn, mediated the pathway from social media micro-influencer characteristics to brand evangelism. Understanding what social media micro-influencers mean to Millennials offers the promise of improving brand evangelism through more precise market analysis and market strategy. In the discussion, the paper introduces a three-stage building method towards brand evangelism through social media micro-influencer, including: (1) the stage of selecting influencers; (2) the stage of constructing intense emotional responses to the brand (brand engagement and brand love); and ultimately (3) the stage of becoming a brand evangelist. Lastly, limitations and future directions were discussed.
毫无疑问,在数字化时代,被认为是数字原住民的千禧一代已经成为销售人员的巨大目标市场。随着社交媒体的爆炸式增长,千禧一代思维方式的变化导致公司部门越来越关注社交媒体影响者营销。为了帮助建立一个新的营销模式来解释这些变化,本研究旨在概念化和调查通过社交媒体微影响者与千禧一代消费者建立消费者品牌关系的过程。基于结构方程模型的研究结果显示,社交媒体微影响者的四个核心特征(真实性、影响者的意义、具体内容和秘密分享)是品牌参与和品牌喜爱的重要前提,而品牌参与和品牌喜爱又介导了社交媒体微影响者特征到品牌传播的路径。了解社交媒体微影响者对千禧一代的意义,有助于通过更精确的市场分析和市场策略改善品牌宣传。在讨论中,本文介绍了利用社交媒体微影响者进行品牌布道的三阶段构建方法,包括:(1)选择影响者阶段;(2)构建对品牌的强烈情感反应阶段(品牌参与和品牌热爱);最终(3)成为品牌传播者的阶段。最后,讨论了研究的局限性和未来发展方向。

The Limits of Marketplace Fee Discrimination 市场收费歧视的限度
Pub Date : 2021-04-01 DOI: 10.2139/ssrn.3729378
M. Tremblay
Platforms often use fee discrimination within their marketplace (e.g., Amazon, eBay, and Uber specify a variety of merchant fees). To better understand the impact of marketplace fee discrimination, we develop a model that allows us to determine equilibrium fee and category decisions that depend on the extent of fee discrimination available to the platform and we highlight how our fee discrimination strategies can be derived in practice using data from airbnb.com. In addition, we find that greater fee discrimination allows the platform to serve more markets in its marketplace but also increases fees in high surplus markets. However, if the platform enters into retail, then the platform reduces its fees and generates greater retail competition. These effects mitigate distortions from fee discrimination and improve welfare. In terms of policy, we show that (1) banning fee discrimination and platform entry is detrimental to welfare, (2) a vertical merger within a retail market mitigates fee distortions but is often worse than an equilibrium with platform entry into retail, and (3) taxing the platform in retail (not merchants) levels the retail playing field and can generate a Pareto improvement upon a policy that bans platform retail entry.
平台通常在其市场中使用费用歧视(例如,亚马逊、eBay和Uber指定了各种商家费用)。为了更好地理解市场费用歧视的影响,我们开发了一个模型,使我们能够根据平台可获得的费用歧视程度来确定平衡费用和类别决策,我们强调了如何使用airbnb.com的数据在实践中推导出我们的费用歧视策略。此外,我们发现,更大的费用歧视可以让平台在其市场中服务更多的市场,但也会增加高剩余市场的费用。但是,如果平台进入零售,那么平台就会降低其费用,从而产生更大的零售竞争。这些影响减轻了收费歧视造成的扭曲,并改善了福利。在政策方面,我们表明(1)禁止费用歧视和平台进入不利于福利,(2)零售市场内的垂直合并减轻了费用扭曲,但通常比平台进入零售业的均衡更糟糕,(3)对零售平台(而不是商家)征税使零售竞争环境更加公平,并可以在禁止平台零售进入的政策上产生帕累托改进。

Are Mobile Money and Financial Accounts Complementary? Evidence from the WAEMU Region 移动货币和金融账户是互补的吗?来自西非货币联盟地区的证据
Pub Date : 2021-03-16 DOI: 10.2139/ssrn.3805905

The recent mobile money innovation has experienced strong development and has been a key tool for financial inclusion in sub-Saharan Africa. Even holders of formal financial accounts have adopted it widely. Based on a sample of 6,891 households in the West African Economic and Monetary Union (WAEMU), we study complementarity between the use of mobile money and financial accounts. Our empirical results show that households generally perceive mobile money and financial accounts as substitutes. We also found that individuals for whom the two accounts are complementary have a high level of education and live in countries where formal financial and mobile money services are more accessible. Moreover, contrary to previous works, we show that among those holding two complementary accounts, almost 50% find that the formal financial account is a complement of mobile money. We attribute this preference to a very low use of financial services such as formal savings and borrowings in WAEMU.
最近的移动支付创新经历了强劲的发展,并已成为撒哈拉以南非洲地区普惠金融的关键工具。即使是拥有正式金融账户的人也广泛采用了这种方式。基于西非经济与货币联盟(WAEMU)的6,891个家庭样本,我们研究了移动货币使用与金融账户之间的互补性。我们的实证结果表明,家庭普遍将移动货币和金融账户视为替代品。我们还发现,这两个账户互补的个人教育水平较高,并且生活在正规金融和移动货币服务更容易获得的国家。此外,与之前的工作相反,我们表明,在拥有两个互补账户的人中,近50%的人认为正规金融账户是移动货币的补充。我们将这种偏好归因于WAEMU中正规储蓄和借贷等金融服务的使用率非常低。

Does online interaction between firms and investors reduce stock price crash risk? 公司和投资者之间的在线互动是否会降低股价崩溃的风险?
Pub Date : 2021-02-24 DOI: 10.2139/ssrn.3792171
Wei Zhang, Yi Li, Pengfei Wang
This paper examines how online interaction between firm management and investors impacts stock price crash risk. Based on the previous literature, we postulate that online interaction constrains crash risk via two channels, i.e., deterring bad news hoarding activities of managers and decreasing differences of opinion among investors. Relying on the launch of Hudongyi (the first official investor relations management platform in the world) for identification, we demonstrate that online firm-investor interaction significantly reduces future crash risk and that these two channels can both explain this effect. Overall, our findings highlight the important role of online interaction in risk management.
本文考察了公司管理层和投资者之间的在线互动如何影响股价崩盘风险。基于之前的文献,我们假设在线互动通过两个渠道约束崩溃风险,即阻止管理者囤积坏消息的行为和减少投资者之间的意见分歧。通过huddongyi(世界上第一个官方投资者关系管理平台)的推出进行识别,我们证明了在线公司-投资者互动显著降低了未来的崩溃风险,这两个渠道都可以解释这种效应。总的来说,我们的研究结果强调了在线互动在风险管理中的重要作用。

Random Encounters and Information Diffusion about Product Quality 产品质量的随机相遇与信息扩散
Pub Date : 2021-02-07 DOI: 10.2139/ssrn.3801563
J. Gabszewicz, Marco A. Marini, S. Zanaj
This paper explores how social interactions among consumers shape markets. In a two-country model, consumers meet and exchange information about the quality of the goods. As information spreads, the demands evolve, affecting the prices and quantities manufactured by profit-maximizing firms. We show that market prices with informational frictions reach the duopoly price with full information, at the limit. However, this convergence can take two different paths depending on the size asymmetry between countries. In particular, when countries are of very different sizes, the single market does not immediately turn into a duopoly and monopoly prices may persist for several periods. Hence, the price-reducing trade effects may take longer to appear. In view of an intense globalization process, understanding how social meetings affect market outcomes is critical for understanding the performance of international economic integration.
本文探讨了消费者之间的社会互动如何塑造市场。在两国模式中,消费者见面并交换有关商品质量的信息。随着信息的传播,需求不断变化,从而影响利润最大化企业生产的产品的价格和数量。结果表明,存在信息摩擦的市场价格在极限情况下达到完全信息条件下的双寡头垄断价格。然而,这种趋同可以采取两条不同的路径,这取决于国家之间的规模不对称。特别是,当各国的规模差别很大时,单一市场不会立即变成双寡头垄断,垄断价格可能会持续数个时期。因此,降低价格的贸易效应可能需要更长时间才能显现。鉴于激烈的全球化进程,了解社会会议如何影响市场结果对于了解国际经济一体化的表现至关重要。

This study is devoted to the development of approaches to the assessment of macroeconomic indicators, aggregate factor productivity, labor productivity, capital and other indicators in the conditions of digitalization of the national economy. The study applied a methodological framework based on the UN System of National Accounts (SNA 2008), European System of National Accounts (SNA 2010) and specialized developments of international organizations in the field of macroeconomic and digital economy statistics (OECD, IMF, World Bank, etc.). The work measured and accounted for the qualitative characteristics of new products with fundamentally new parameters that had not previously been observed or accounted for in other products. The application of the hedonic method to the data (on the example of the Moscow market) has shown that this method is able to produce results consistent with the conclusions of earlier works.

本研究致力于发展国民经济数字化条件下的宏观经济指标、总要素生产率、劳动生产率、资本等指标的评估方法。本研究采用了基于联合国国民经济核算体系(SNA 2008)、欧洲国民经济核算体系(SNA 2010)以及宏观经济和数字经济统计领域国际组织(经合组织、国际货币基金组织、世界银行等)的专业发展的方法框架。这项工作测量和解释了新产品的质量特征,这些新产品具有以前在其他产品中没有观察到或考虑到的基本新参数。将hedonic方法应用于数据(以莫斯科市场为例)表明,这种方法能够产生与早期工作结论一致的结果。该研究的结果为评估数字化的社会经济影响及其长期后果提供了一个全面的系统。这可以作为俄罗斯进一步实施经济政策时在数字经济领域进行经济预测的依据。

The digital economy has become one of the most important sectors in global GDP.Personal data is the new asset class that creates value through the applications ofcybertechnologies and Artificial Intelligence. However, there are increasing concerns over the privacy invasions and human rights violations associated with the exploitation ofpersonal data.Various data laws were made in nations to balance the data fluidity and privacy protections. However, most laws have inherent limitations and underenforcement issuesthat fail to achieve their aims and protection principles. Utilizing a behavioral economics theoretical framework, this study categorizes the issues and causes to InformationAsymmetry, Bounded Rationality, Power Imbalance, and Technical Incapacity.The study makes a novel contribution by proposing a global data governance scheme to address the limitations of data laws. The scheme adopts a Libertarian Paternalism approach and develops seven principles in the framework design. Elements and components in the scheme include individuals, data controllers, privacy rating frameworks, meta-data and privacy configuration, reports, Automated Consent Management (ACM), Bureaus, and signatures, etc. The components will operate on an interoperable and global data management platform. Visual diagrams are developed to describe the various forms of interactions between components and procedures.A balance between privacy protection and data fluidity is found through experimental scenarios such as Ordinary Data Request, Sensitive Data Request, Inconsistency Checks, Data Rights Exercise, Monitored Data Transfer, Broadcast and Notice. The scenarios analyzed are not exhaustive but serve as the meaningful startingpoint to inspire more designs and discussions from scholars.
数字经济已成为全球GDP中最重要的部门之一。个人数据是通过网络技术和人工智能的应用创造价值的新资产类别。然而,人们越来越关注与个人数据利用相关的隐私侵犯和人权侵犯。各国制定了各种数据法,以平衡数据流动性和隐私保护。然而,大多数法律都存在固有的局限性和执行不力的问题,无法实现其目标和保护原则。本文运用行为经济学的理论框架,对信息不对称、有限理性、权力失衡和技术能力丧失的问题及其成因进行了分类。该研究通过提出一种全球数据治理方案来解决数据法的局限性,做出了新颖的贡献。该方案采用了自由意志主义的家长制方法,并在框架设计中发展了七个原则。方案中的元素和组件包括个人、数据控制器、隐私评级框架、元数据和隐私配置、报告、自动同意管理(ACM)、局和签名等。这些组件将在一个可互操作的全球数据管理平台上运行。开发可视化图表来描述组件和过程之间各种形式的交互。通过普通数据请求、敏感数据请求、不一致检查、数据权利行使、监控数据传输、广播和通知等实验场景,找到隐私保护与数据流动性之间的平衡。所分析的场景并不详尽,但作为一个有意义的起点,可以激发学者们更多的设计和讨论。
