Deutsch Abstract: Der Beitrag analysiert mögliche spezielle Wettbewerbsprobleme, die in Medienmärkten auftreten können, und ihre Implikationen für die Wettbewerbsordnung. Es wird beleuchtet, ob klassische medienspezifische Wettbewerbsprobleme in der Digitalwirtschaft noch bestehen und welche neuen Beschränkungen auftreten, wie bspw. der Zugang zum Publikum als neue Marktzutrittsschranke sowie Gatekeeping-Effekte aufgrund von vertikaler Integration und Selbstbevorzugungsstrategien. Die derzeit stattfindende Ausweitung der wettbewerbspolitischen Missbrauchsaufsicht wird begrüßt, allerdings wird eine hierzu komplementäre aktivere Zusammenschlusskontrolle eingefordert, insbesondere auch gegenüber nicht-horizontalen Fusionen, welche wettbewerbsgefährdende Strukturen in digitalen Ökosystemen schaffen. English Abstract: This paper analyses potential competition problems that are special to media markets and their implications for competition policy. It discusses whether traditional media-specific restraints of competition are still relevant in the digital economy and which new ones tend to surface in digital ecosystems, like e.g. access to the audience as a barrier to entry or gatekeeping effects as a consequence of vertical integration and self-preferencing strategies. The article welcomes the current enhancement and empowerment of antitrust policies combating market power abuses by companies with significant relevance within digital ecosystems. However, it additionally demands to invigorate merger control, in particular also against non-horizontal mergers within digital ecosystems.

Network Externalities and Consolidation in the Dating Website Industry 交友网站行业的网络外部性与整合
Pub Date : 2021-07-14 DOI: 10.2139/ssrn.3760700
Michael Sullivan
Network externalities—i.e., effects on consumers' alternative-specific pay-offs of other consumers' decisions—arise in many economic settings. This paper considers the identification of discrete-choice models featuring network externalities and then uses such a model to analyze how network externalities in the market for dating websites in the United States contribute to the effects of consolidation in that industry. My identification analysis shows that discrete-choice models with network externalities are generally not identified with market-level data alone, but that microdata allows the researcher to construct instrumental variables that identify the model. Using rich online browsing data, I estimate a model of consumer choice of dating website and find evidence of considerable network externalities. In my preferred specification, an inframarginal user of a site values a 10% increase in the site's usership at $11.11/month, which is about one third of the most popular site's price. I use my estimates to assess whether the observed extent of network externalities imply that increased market concentration would benefit consumers. I find that welfare losses from decreased variety and increased prices outweigh the gains from network externalities associated with a move from the observed market structure to monopoly. Platform differentiation may explain why platform integration has not followed consolidation in the dating websites industry.
网络externalities-i.e。在许多经济环境中,对消费者选择的影响——其他消费者决策的特定回报——都会出现。本文考虑了具有网络外部性的离散选择模型的识别,然后使用这样的模型来分析美国约会网站市场的网络外部性如何促进该行业整合的影响。我的识别分析表明,具有网络外部性的离散选择模型通常不会仅由市场层面的数据识别,但微观数据允许研究人员构建识别模型的工具变量。利用丰富的在线浏览数据,我估计了一个消费者选择约会网站的模型,并找到了相当大的网络外部性的证据。在我的首选规范中,网站的超边际用户以11.11美元/月的价格为网站用户增加10%的价值,这大约是最受欢迎网站价格的三分之一。我用我的估计来评估观察到的网络外部性的程度是否意味着增加的市场集中度将使消费者受益。我发现品种减少和价格上涨带来的福利损失超过了从观察到的市场结构转向垄断所带来的网络外部性带来的收益。平台差异化或许可以解释为什么交友网站行业没有出现整合之后的平台整合。

The Role of "Live" in Livestreaming Markets: Evidence Using Orthogonal Random Forest “直播”在直播市场中的作用:使用正交随机森林的证据
Pub Date : 2021-07-02 DOI: 10.2139/ssrn.3878605
Ziwei Cong, Jia Liu, Puneet Manchanda
The common belief about the growing medium of livestreaming is that its value lies in its "live" component. In this paper, we leverage data from a large livestreaming platform to examine this belief. We are able to do this as this platform also allows viewers to purchase the recorded version of the livestream. We summarize the value of livestreaming content by estimating how demand responds to price before, on the day of, and after the livestream. We do this by proposing a generalized Orthogonal Random Forest framework. This framework allows us to estimate heterogeneous treatment effects in the presence of high-dimensional confounders whose relationships with the treatment policy (i.e., price) are complex but partially known. We find significant dynamics in the price elasticity of demand over the temporal distance to the scheduled livestreaming day and after. Specifically, demand gradually becomes less price sensitive over time to the livestreaming day and is inelastic on the livestreaming day. Over the post-livestream period, demand is still sensitive to price, but much less than the pre-livestream period. This indicates that the value of livestreaming persists beyond the live component. Finally, we provide suggestive evidence for the likely mechanisms driving our results. These are quality uncertainty reduction for the patterns pre- and post-livestream and the potential of real-time interaction with the creator on the day of the livestream.
对于不断增长的直播媒体,人们普遍认为它的价值在于它的“直播”成分。在本文中,我们利用来自大型直播平台的数据来检验这一信念。我们能够做到这一点,因为这个平台也允许观众购买直播的录制版本。我们通过估算直播前、直播当天和直播后的需求对价格的反应来总结直播内容的价值。为此,我们提出了一个广义正交随机森林框架。这个框架允许我们在高维混杂因素存在的情况下估计异质性治疗效果,这些混杂因素与治疗政策(即价格)的关系是复杂的,但部分已知。我们发现需求的价格弹性在预定直播日和之后的时间距离上有显著的动态变化。具体来说,随着时间的推移,需求对直播日的价格敏感性逐渐降低,并且在直播日没有弹性。在直播后阶段,需求仍然对价格敏感,但远低于直播前阶段。这表明,直播的价值持续存在于直播组件之外。最后,我们为驱动我们结果的可能机制提供了启发性证据。这些是减少直播前后模式的质量不确定性,以及在直播当天与创作者进行实时互动的潜力。

Import Competition and Firms' Internal Networks 进口竞争与企业内部网络
Pub Date : 2021-07-01 DOI: 10.2139/ssrn.3882794
Jay Hyun, Ziho Park, V. Smirnyagin
Using administrative data on U.S. multisector firms, we document a cross-sectoral propagation of the import competition from China (“China shock”) through firms’ internal networks: Employment of an establishment in a given industry is negatively affected by China shock that hits establishments in other industries within the same firm. This indirect propagation channel affects both manufacturing and non-manufacturing establishments, and it operates primarily through the establishment exit. We explore a range of explanations for our findings, highlighting the role of within-firm trade across sectors, scope of production, and establishment size. At the sectoral aggregate level, China shock that propagates through firms’ internal networks has a sizable impact on industry-level employment dynamics.
利用美国多部门公司的管理数据,我们通过公司内部网络记录了来自中国的进口竞争的跨部门传播(“中国冲击”):中国冲击冲击同一公司内其他行业的机构,对特定行业机构的就业产生负面影响。这种间接传播渠道既影响制造业也影响非制造业企业,它主要通过企业退出来运作。我们对研究结果进行了一系列解释,强调了跨部门、生产范围和企业规模的企业内部贸易的作用。在行业总体水平上,通过企业内部网络传播的中国冲击对行业层面的就业动态具有相当大的影响。

The Economic Effects of Firm-Level Uncertainty: Evidence Using Subjective Expectations 企业层面不确定性的经济效应:基于主观预期的证据
Pub Date : 2021-06-28 DOI: 10.2139/ssrn.3896313
G. Fiori, Filippo Scoccianti
This paper uses over two decades of Italian survey data on business managers' expectations to measure subjective firm-level uncertainty and quantify its economic effects. We document that firm-level uncertainty persists for a few years and varies across firms' demographic characteristics. Uncertainty induces long-lasting economic effects over a broad array of real and financial variables. The source of uncertainty matters with firms responding only to downside uncertainty, that is, uncertainty about future adverse outcomes. Economy-wide uncertainty, constructed aggregating firm-level uncertainty, is countercyclical but uncorrelated with typical proxies in the literature, and accounts for a sizable amount of GDP variation during crises.
本文利用二十多年来意大利对企业管理者期望的调查数据来衡量主观企业层面的不确定性,并量化其经济影响。我们证明,企业层面的不确定性会持续几年,并因企业的人口特征而异。不确定性会对一系列广泛的实际和金融变量产生长期的经济影响。不确定性的来源与企业只对下行不确定性(即未来不利结果的不确定性)做出反应有关。整体经济的不确定性,构建了企业层面的不确定性,是逆周期的,但与文献中的典型代理不相关,并且在危机期间解释了相当大的GDP变化。

Automobile Replacement and Government Subsidy: An Analysis of the CARS Program 汽车置换与政府补贴:对CARS计划的分析
Pub Date : 2021-06-24 DOI: 10.2139/ssrn.3873076

Subsidy programs are widely used by governments to stimulate durable goods sectors. This paper investigates the impact of government subsidy on consumers' automobile replacement decisions in the context of the U.S. Car Allowance and Rebate System program in 2009. I develop and estimate a dynamic discrete-choice model of automobile replacement, and conduct counterfactual analysis to evaluate the effects of government subsidies. Results show that 65% of the households would replace their vehicles even without the subsidy, and the reductions in gasoline consumption and carbon emission are limited. To highlight the impact of subsidy design, I show that limiting the subsidy to low-income consumers would generate 85% of the sales with half amount of total government spending. These findings emphasize the importance of balancing policy stimulus with government spending and targeting consumers more efficiently in the design of subsidy programs.
补贴计划被政府广泛用于刺激耐用品行业。本文以2009年美国汽车补贴与返利制度为背景,研究政府补贴对消费者汽车更换决策的影响。建立并估计了汽车更换的动态离散选择模型,并进行了反事实分析来评估政府补贴的效果。结果表明,即使没有补贴,仍有65%的家庭愿意更换车辆,并且汽油消耗和碳排放的减少是有限的。为了突出补贴设计的影响,我表明限制对低收入消费者的补贴将产生85%的销售额,而政府总支出为一半。这些发现强调了平衡政策刺激与政府支出以及在补贴计划设计中更有效地针对消费者的重要性。

Regulating Powerful Platforms: Evidence from Commission Fee Caps in On-Demand Services 监管强大的平台:来自按需服务佣金上限的证据
Pub Date : 2021-06-22 DOI: 10.2139/ssrn.3871514

Owners of multi-sided platforms typically possess strong power over complementors. Such power asymmetry gives platform owners the edge on setting high platform fees to capture most of the surplus created on their platforms. While there is a heated debate on regulating these powerful platforms, the lack of empirical studies hinders the progress towards evidence-based policymaking. This research empirically investigates this regulatory issue in the context of on-demand delivery. Delivery platforms (e.g., DoorDash, Grubhub, and Uber Eats) charge restaurants a commission fee, which can be as high as 30% of the order amount. To support small businesses, recent regulatory scrutiny has attempted to cap the commission fees for independent restaurants. This research empirically evaluates the effects of platform fee regulations on restaurants, by investigating recent regulations across 14 cities and states in the United States. Our analyses show that independent restaurants in regulated cities (i.e., those paying reduced commission fees) experience a decline in orders and revenue, whereas chain restaurants (i.e., those paying the original fees) see an increase in orders and revenue. This intriguing finding suggests that chain restaurants, not independent restaurants, benefit from the regulations that were intended to support independent restaurants. We find that platforms’ responses to the regulations may explain the negative effects on independent restaurants. That is, after cities enact policies to cap platforms’ commission fees, delivery platforms become less likely to recommend independent restaurants to consumers, and instead turn to promote chain restaurants or nearby restaurants from non-regulated cities. Moreover, delivery platforms increase their delivery fees for consumers in regulated cities, suggesting that these platforms attempt to cover the loss of commission revenue by charging customers more. These findings provide empirical evidence for policymakers to evaluate the effectiveness of platform fee regulations.
多边平台的所有者通常对互补者拥有强大的权力。这种权力不对称使平台所有者在设定高额平台费用以获取其平台上产生的大部分盈余方面具有优势。虽然对这些强大平台的监管存在激烈的争论,但缺乏实证研究阻碍了循证决策的进展。本研究在按需配送的背景下对这一监管问题进行了实证研究。外卖平台(如DoorDash、Grubhub和Uber Eats)向餐馆收取佣金,最高可达订单金额的30%。为了支持小企业,最近的监管审查试图限制独立餐馆的佣金。本研究通过调查美国14个城市和州的最新法规,实证评估了平台收费法规对餐馆的影响。我们的分析表明,在受监管的城市中,独立餐厅(即那些支付佣金减少的餐厅)的订单和收入下降,而连锁餐厅(即那些支付原始费用的餐厅)的订单和收入则有所增加。这一有趣的发现表明,连锁餐厅,而不是独立餐厅,受益于旨在支持独立餐厅的法规。我们发现,平台对法规的反应可以解释对独立餐厅的负面影响。也就是说,在城市颁布了限制平台佣金的政策后,外卖平台不太可能向消费者推荐独立餐厅,而是转向推广来自不受监管城市的连锁餐厅或附近餐厅。此外,外卖平台提高了受监管城市消费者的配送费用,这表明这些平台试图通过向客户收取更多费用来弥补佣金收入的损失。这些发现为政策制定者评估平台收费监管的有效性提供了实证依据。

Flipping the Coin: Are Spacs Post-Merger Value-Creating or Value-Destroying? An Empirical Study on the Value Effects of Special Purpose Acquisition Companies in the United States 抛硬币:合并后的航天是创造价值还是破坏价值?美国特殊目的收购公司价值效应实证研究
Pub Date : 2021-06-10 DOI: 10.2139/ssrn.3872422
Koen Bodewes
This study examines the merger announcement and post-announcement value effects of special purpose acquisition company (“SPAC”) transactions in the United States from January 2010 up to March 2021. It finds positive cumulative abnormal merger announcement returns (“CARs”) and negative long-term buy-and-hold abnormal returns (“BHARs”) post-announcement - consistent with previous research. The short-term effect is considerably larger (10.50%) for post-COVID SPACs, with faster deals, fewer redemptions, and more frequent PIPE involvement during bull markets with high market volatility and a low cost of debt. The BHARs are on average positive up until 15 months after merger announcement and negative afterwards. This study shows the effect of long-term performance is influenced by several SPAC characteristics. Firstly, the post-merger performance is better for SPACs with management with C-suite operational experience. Surprisingly though, prior experience of managers with SPAC transactions is not indicative of future results, as serial sponsors consistently underperform first-time sponsors. Secondly, SPAC deals with a higher proportion of PIPE financing show superior long-term performance, due to external deal validation leading to fewer redemptions. This study contributes to the limited existing literature on the post-merger effects of SPACs, by introducing new explanatory variables, performing multivariate regressions, and incorporating post-COVID SPAC mergers, leading to larger sample sizes. Given recent SPAC popularity, my findings have important implications for U.S. public market investors, corporate finance advisors, regulators and early-stage companies considering merging with a SPAC.
本研究考察了2010年1月至2021年3月期间美国特殊目的收购公司(“SPAC”)交易的合并公告和公告后价值效应。研究发现,并购公告后的累积异常收益为正,公告后的长期买入并持有异常收益为负,这与之前的研究结果一致。对于后covid - 19的SPACs,短期影响要大得多(10.50%),交易更快,赎回更少,在市场波动大、债务成本低的牛市期间,PIPE参与更频繁。在宣布合并后的15个月内,bhr平均为正,之后为负。本研究表明,长期绩效的影响受到几个SPAC特征的影响。首先,拥有高管层运营经验的SPACs合并后绩效更好。然而,令人惊讶的是,SPAC交易经理的先前经验并不代表未来的结果,因为连续发起人的表现始终不如首次发起人。其次,由于外部交易验证导致赎回较少,SPAC交易中PIPE融资比例较高的交易表现出较好的长期绩效。本研究通过引入新的解释变量,进行多变量回归,并纳入covid后的SPAC合并,从而扩大了样本量,从而弥补了现有关于SPAC合并后影响的有限文献。鉴于最近SPAC的流行,我的研究结果对美国公开市场投资者、企业财务顾问、监管机构和考虑与SPAC合并的早期公司具有重要意义。

It finds positive cumulative abnormal merger announcement returns (“CARs”) and negative long-term buy-and-hold abnormal returns (“BHARs”) post-announcement - consistent with previous research. The short-term effect is considerably larger (10.50%) for post-COVID SPACs, with faster deals, fewer redemptions, and more frequent PIPE involvement during bull markets with high market volatility and a low cost of debt. The BHARs are on average positive up until 15 months after merger announcement and negative afterwards. This study shows the effect of long-term performance is influenced by several SPAC characteristics. Firstly, the post-merger performance is better for SPACs with management with C-suite operational experience. Surprisingly though, prior experience of managers with SPAC transactions is not indicative of future results, as serial sponsors consistently underperform first-time sponsors. Secondly, SPAC deals with a higher proportion of PIPE financing show superior long-term performance, due to external deal validation leading to fewer redemptions. This study contributes to the limited existing literature on the post-merger effects of SPACs, by introducing new explanatory variables, performing multivariate regressions, and incorporating post-COVID SPAC mergers, leading to larger sample sizes. Given recent SPAC popularity, my findings have important implications for U.S. public market investors, corporate finance advisors, regulators and early-stage companies considering merging with a SPAC.","PeriodicalId":430354,"journal":{"name":"IO: Empirical Studies of Firms & Markets eJournal","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116074587","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}

Price Reference Effects and Vertical Contracts in the Book Retail Market
Pub Date : 2021-06-05 DOI: 10.2139/ssrn.3861004

In many settings, behavioral economists have documented a price reference effect: the fact that a consumer's willingness to pay for a good is affected by difference between the observed price and the reference price they rationally expect. In this paper, we show that such preferences interact with vertical contracting in a way that can overturn standard textbook intuition. In particular, we show that if this price reference effect is sufficiently large, vertical integration between an upstream producer and a downstream retailer can decrease joint profits, unlike in the textbook case where vertical integration improves profits. The key intuition is that the increase in quantity is smaller when consumers expect lower prices in the new equilibrium. To test whether this force is large in a real-world setting, we develop a model of a downstream retailer who faces behavioral consumers and bargains with an upstream producer. We estimate this model using a novel dataset from a large online book retailer, where we observed retail prices, quantities sold and wholesale prices. Counterfactual simulations show that vertical integration would reduce joint profits by 11%. These findings highlight the importance of incorporating consumer expectations in the analysis of optimal pricing and firm profits.
在许多情况下,行为经济学家已经证明了价格参考效应:消费者购买商品的意愿受到观察到的价格与他们理性预期的参考价格之间差异的影响。在本文中,我们展示了这种偏好与垂直收缩的相互作用,这种方式可以推翻标准的教科书直觉。特别是,我们表明,如果这种价格参考效应足够大,上游生产商和下游零售商之间的垂直整合会降低共同利润,这与教科书中垂直整合提高利润的案例不同。关键的直觉是,在新的均衡中,当消费者预期价格较低时,数量的增加较小。为了测试这种力量在现实世界中是否很大,我们建立了一个下游零售商的模型,该零售商面对行为消费者并与上游生产商讨价还价。我们使用一个来自大型在线图书零售商的新数据集来估计这个模型,我们观察了零售价格、销售数量和批发价格。反事实模拟表明,垂直整合将使联合利润减少11%。这些发现突出了在最优定价和企业利润分析中纳入消费者期望的重要性。

Firm Size and Pharmaceutical Mergers: A Cross-National, Cross-Sector Perspective 企业规模与制药企业合并:一个跨国、跨部门的视角
Pub Date : 2021-05-31 DOI: 10.2139/ssrn.3874139

Mergers in the pharmaceutical sector warrant special scrutiny not only because of concerns over affordability of medicines, but also because the institutional details of pharmaceutical markets complicate the economic analysis of merger effects. Standard anti-trust analysis of mergers, in pharmaceuticals as in other industries, focuses on the proposed merger’s potential to raise prices or reduce innovation by eliminating potential competitors in individual product markets defined by substitutability and geography. Ignored by this exclusive focus on individual markets is the potential for horizontal mergers to increase market power though leverage and cross-market effects enabled by large portfolios that span individual markets.

The thesis of this paper is that leverage and cross-market effects exist in pharmaceutical markets and can be exacerbated by mergers because larger firms have bargaining leverage and other advantages in dealing with reimbursement, marketing and selling in pharmaceutical markets. The relevant institutional details — and the potential risks to competition — differ across countries and between originator and generic drugs. An earlier paper outlined these potential cross-market effects in mergers of originator pharmaceutical firms in the US. This paper extends the analysis to examine how far similar cross-market effects are also a concern in mergers of originator firms in Europe and for generic firms in the US and Europe. It concludes that cross-market effects are potentially of greatest concern for originator pharmaceutical mergers and, to lesser extent, for generics mergers in the US, because the US healthcare system relies primarily on market forces rather than regulation to assure consumer welfare. While cross-market concerns could arise in pharmaceutical mergers in Europe, they are substantially mitigated by various regulatory features of European pharmaceutical markets.
制药部门的合并需要特别审查,这不仅是因为对药品负担能力的担忧,还因为制药市场的制度细节使合并效应的经济分析复杂化。制药业和其他行业的标准反垄断合并分析,关注拟议的合并是否有可能通过消除由可替代性和地理位置决定的单个产品市场上的潜在竞争者,从而提高价格或减少创新。这种对单个市场的独家关注忽视了横向合并的潜力,这种潜力可以通过跨越单个市场的大型投资组合带来的杠杆和跨市场效应来增强市场力量。本文的论点是,杠杆效应和跨市场效应存在于医药市场中,并且由于大公司在医药市场的报销、营销和销售方面具有议价杠杆和其他优势,并购可能会加剧杠杆效应和跨市场效应。相关的制度细节——以及潜在的竞争风险——在不同的国家以及原产药和仿制药之间有所不同。早些时候的一篇论文概述了这些潜在的跨市场效应在美国原产制药公司的合并。本文扩展了分析,以检验在欧洲的原创公司合并以及美国和欧洲的仿制公司合并中,类似的跨市场效应在多大程度上也是一个问题。它的结论是,跨市场效应可能是最令人担忧的原创制药合并,而在较小程度上是美国仿制药合并,因为美国医疗保健系统主要依靠市场力量,而不是监管来确保消费者福利。虽然欧洲制药企业合并可能出现跨市场问题,但欧洲制药市场的各种监管特点大大减轻了这些问题。
