Scholarship on competition policy has begun to explore the implications of learning from behavioral research and to challenge the assumption of profit maximization at the heart of neoclassical economic theory of the firm. This scholarship is briefly reviewed, focusing on merger control. Prospects for basing merger control entirely on data from actual mergers or laboratory experiments are explored. Also explored are implications of behavioral research for merger assessment in consumer-goods industries. The conclusion is that competition policy should continue to rely on neoclassical economic analysis based on the assumption of profit maximization.
竞争政策方面的学术研究已经开始探索从行为研究中学习的含义,并开始挑战新古典经济企业理论核心的利润最大化假设。本文简要回顾了这方面的研究,重点是合并控制。探讨了完全基于实际合并或实验室实验数据的合并控制的前景。还探讨了行为研究对消费品行业并购评估的影响。结论是,竞争政策应继续依赖于基于利润最大化假设的新古典经济学分析。

Do Government Agencies Respond to Market Pressures? Evidence from Private Prisons 政府机构会对市场压力做出反应吗?来自私人监狱的证据

This paper examines the role of privatization on the cost of government-provided services. We examine data on the cost of housing public and private prisoners from all 50 states over the time period 1996-2004, and find that the existence of private prisons in a state reduces the growth in per prisoner expenditures by public prisons by a statistically significant amount. In 2004, the average Department of Corrections expenditures in states without private prisoners was approximately $493 million. Our findings suggest that if the "average" state in that group were to introduce the use of private prisons, the potential savings for one year in Department of Corrections expenditures for public prisons could be approximately $13 to $15 million for that particular hypothetical state. These savings on public prisons would be in addition to any direct savings from the use of private prisons by itself.
本文探讨了私有化对政府提供服务成本的影响。我们研究了1996年至2004年期间全美50个州的公共和私人囚犯的住房成本数据,发现在一个州,私人监狱的存在在统计上显著地降低了公共监狱每个囚犯支出的增长。2004年,惩教署在没有私人囚犯的州的平均支出约为4.93亿美元。我们的研究结果表明,如果这一组中的“平均”州引入了私人监狱的使用,那么对于这个特定的假设州来说,惩教部一年用于公共监狱的支出可能节省大约1300万到1500万美元。除了使用私人监狱本身所节省的任何直接开支外,这些公共监狱的开支也将节省下来。

Sex Discrimination in the Labor Market 劳动力市场中的性别歧视
Pub Date : 2007-01-02 DOI: 10.1561/0700000007
J. Hersch
This paper examines sources of gender pay disparity and the factors that contribute to this pay gap. Many researchers question the role of discrimination and instead attribute the residual pay gap to gender differences in preferences. The main issue considered in this paper is whether gender differences in choices, especially with respect to the family and household, are indeed responsible for the gender pay gap, or whether discrimination plays a role. On balance, the evidence indicates that sex discrimination remains a possible explanation of the unexplained gender pay gap. This is consistent with the continuing high profile sex discrimination litigation suggestive of on-going inferior treatment on the basis of sex.
本文探讨了性别薪酬差距的来源以及造成这种薪酬差距的因素。许多研究人员质疑歧视的作用,而是将剩余的薪酬差距归因于性别偏好的差异。本文考虑的主要问题是,在选择方面的性别差异,特别是在家庭和家庭方面,是否确实是造成性别收入差距的原因,或者歧视是否起了作用。总的来说,证据表明,性别歧视仍然是无法解释性别薪酬差距的一个可能解释。这与持续不断的引人注目的性别歧视诉讼是一致的,这些诉讼表明,基于性别的待遇一直很差。

Network Regulation: The Many Faces of Access 网络监管:接入的多面性
Pub Date : 2005-06-08 DOI: 10.2139/ssrn.740297
Daniel F. Spulber, C. S. Yoo
Telecommunications regulation has experienced a fundamental shift from rate regulation to increased reliance on compelled access, perhaps best exemplified by the Telecommunications Act of 1996's imposition of no fewer than four new access requirements. Unfortunately, each access requirement is governed by a separate set of rules for determining both the scope and the price of access. The resulting ad hoc regime has created difficult definitional problems and opportunities for regulatory arbitrage. In this article we propose a system inspired by the discipline of mathematics known as graph theory that integrates all of the different forms of access into a single analytical framework. This system separates different access regimes into five categories: (1) retail access, (2) wholesale access, (3) interconnection access, (4) platform access, and (5) unbundled access. It also provides insights into how each type of access complicates the already difficult problems of network configuration and management and introduces inefficient biases into decisions about network capacity and design. The approach we propose also provides insights into the transaction cost implications of the different types of access. Drawing on the Coasean theory of the firm, our approach examines the tradeoffs between internal governance costs and the external transaction costs of providing access to offer a theory of network boundaries. This framework shows how access regulation distorts networks' natural boundaries and provides a basis for evaluating whether private ordering through markets would lead to more efficient network design.
电信监管经历了从费率监管到越来越依赖强制接入的根本性转变,也许最好的例子是1996年《电信法》(Telecommunications Act of 1996)强加了不少于四项新的接入要求。不幸的是,每个访问需求都由一组单独的规则控制,用于确定访问的范围和价格。由此产生的临时机制造成了难以界定的问题,并为监管套利创造了机会。在这篇文章中,我们提出了一个被称为图论的数学学科启发的系统,它将所有不同形式的访问集成到一个单一的分析框架中。该系统将不同的接入机制分为五类:(1)零售接入,(2)批发接入,(3)互联接入,(4)平台接入,(5)非捆绑接入。本文还深入介绍了每种类型的访问如何使本已困难的网络配置和管理问题复杂化,并在有关网络容量和设计的决策中引入了低效的偏差。我们提出的方法还提供了对不同类型访问的交易成本含义的见解。利用科斯公司理论,我们的方法考察了内部治理成本和提供访问的外部交易成本之间的权衡,从而提出了网络边界理论。该框架显示了准入监管如何扭曲网络的自然边界,并为评估通过市场进行的私人排序是否会导致更有效的网络设计提供了基础。

Competition and Confidentiality: Signaling Quality in a Duopoly When There is Universal Private Information 竞争与保密:双寡头垄断中普遍存在私有信息时的信号质量
Pub Date : 2004-07-01 DOI: 10.2139/ssrn.566823

How does the need to signal quality through price affect equilibrium pricing and profits, when a firm faces a similarly-situated rival? In this paper, we provide a model of non-cooperative signaling by two firms that compete over a continuum of consumers. We assume "universal incomplete information;" that is, each market participant has some private information: each consumer has private information about the intensity of her preferences for the firms' respective products and each firm has private information about its own product's quality. We characterize a symmetric separating equilibrium in which each firm's price reveals its respective product quality. We focus mainly on a model in which the quality attribute is safety (so that the legal system is brought into play) and quality is unobservable due to the use of confidential settlements; a particular specification of parameters yields a common model from the industrial organization literature in which quality is interpreted as the probability that a consumer will find the good satisfactory. We show that the equilibrium prices, the difference between those prices, the associated outputs, and profits are all increasing functions of the ex ante probability of high safety. When quality is interpreted as consumer satisfaction, unobservable quality causes all prices to be distorted upward, and lowers average quality and ex ante expected social welfare, but increases ex ante expected firm profits (when either the probability of high quality or the extent of horizontal product differentiation is sufficiently high). When quality is interpreted as product safety, the foregoing results are modified in that for some parameter values ex ante expected social welfare is higher under confidentiality because such legal secrecy lowers expected litigation costs.
当一个公司面对一个处境相似的竞争对手时,通过价格表明质量的需求如何影响均衡定价和利润?在本文中,我们提供了一个非合作信号的模型,由两个公司在一个连续的消费者竞争。我们假设“普遍不完全信息”,也就是说,每个市场参与者都有一些私人信息:每个消费者都有关于她对公司各自产品偏好程度的私人信息,每个公司都有关于自己产品质量的私人信息。我们描述了一个对称分离均衡,其中每个公司的价格揭示了其各自的产品质量。我们主要关注一种模式,其中质量属性是安全(以便法律制度发挥作用),由于使用保密结算,质量是不可观察的;一个特定的参数规范产生了一个来自工业组织文献的通用模型,在这个模型中,质量被解释为消费者对商品满意的概率。我们证明了均衡价格、这些价格之间的差异、相关的产出和利润都是高安全性先验概率的递增函数。当质量被解释为消费者满意度时,不可观察的质量导致所有价格向上扭曲,降低了平均质量和事前预期的社会福利,但增加了事前预期的企业利润(当高质量的概率或横向产品差异化的程度足够高时)。当质量被解释为产品安全时,上述结果被修正为对于某些参数值,在保密情况下预期的社会福利更高,因为这种法律保密降低了预期的诉讼成本。

Collaborative Corporate Governance: Listing Standards, State Law and Federal Regulation 协同公司治理:上市标准、州法律和联邦法规
Pub Date : 2003-08-05 DOI: 10.2139/SSRN.429621

The traditional view of corporate law as arising from state law, with federal law in a supporting role no longer describes the post Sarbanes-Oxley world. This paper presents modern corporate governance as a collaborative process between the federal government (mostly acting through the SEC), state law (mostly acting through the Delaware courts, but also including its legislature and those in other states) and the self-regulatory organizations such as the stock exchanges. The focus is on the third source, particularly the listing requirements of the New York Stock Exchange. The Reforms announced in 2002 portend a dramatic increase in the role of the listing requirement in defining American corporate governance. The interaction between the NYSE and state and federal law is heavily tilted toward its overlap with federal law. The pattern of NYSE regulation of the last decade is that the SEC chair makes a speech or a telephone call identifying a problem, the Exchange convenes a committee of experts and proposes a solution that is sent to the SEC and the various interested parties engage the Exchange and the SEC in discussions about what the law should be. Prominent examples include requirements for independent directors, shareholder approval of stock options, audit committee procedures and one share/one vote rules. This is a different process than what occurs in state law or in direct SEC regulation and it is becoming a larger part of American corporate governance.
公司法起源于州法,联邦法起辅助作用的传统观点不再适用于萨班斯-奥克斯利法案后的世界。本文将现代公司治理描述为联邦政府(主要通过美国证券交易委员会行事)、州法律(主要通过特拉华州法院行事,但也包括其立法机构和其他州的立法机构)和证券交易所等自我监管组织之间的协作过程。重点是第三个来源,特别是纽约证券交易所的上市要求。2002年宣布的改革预示着上市要求在定义美国公司治理方面的作用将大幅增强。纽交所与州和联邦法律之间的互动严重倾向于与联邦法律重叠。过去十年,纽交所的监管模式是:SEC主席发表演讲或打电话指出问题,交易所召集一个专家委员会,提出解决方案,并将其提交给SEC,各利益相关方与交易所和SEC就法律应该是什么进行讨论。突出的例子包括要求独立董事、股东批准股票期权、审计委员会程序和一股一票规则。这是一个不同于州法律或证券交易委员会直接监管的过程,它正在成为美国公司治理的一个更大的组成部分。

Securities Fraud as Corporate Governance: Reflections Upon Federalism 证券欺诈作为公司治理:对联邦制的反思
Pub Date : 2002-12-15 DOI: 10.2139/SSRN.362860
R. Thompson, Hillary A. Sale
Federal securities law and enforcement via securities fraud class actions today has become the most visible presence in regulating corporate governance. State law, long at center stage in discussions of corporate governance, continues to provide the legal skeleton for the corporate form and state fiduciary duty litigation continues as a frequent means to monitor managers. Yet, in today's world, state law does so almost entirely in the specific contexts of decisions about acquisitions or in self-dealing transactions. The empirical evidence in this Article illustrates that corporate governance outside of these areas has passed to federal law and in particular to shareholder litigation under Rule 10b-5. The Sarbanes-Oxley Act of 2002, passed by Congress in the wake of the current corporate accountability scandals, provides new evidence of the expanded role of federal law. But, the move to federal corporate governance is broader than that law and has a longer history than the current scandals. The ascendancy of federal law in corporate governance reflects at least three factors. First, disclosure has become the most important method to regulate corporate managers and disclosure has been predominantly a federal, not a state, methodology. Second, state law has focused largely on the duties and liabilities of directors, and not officers, and federal law has increasingly occupied the space defining the duties and liabilities of officers. Officers have become the fulcrum of governance in today's corporations. Third, federal shareholder litigation based on securities fraud has several practical advantages over state shareholder litigation based on fiduciary duty that have contributed to the greater use of the federal forum. As a result of these trends, federal law now occupies the largest part of the legal corporate governance infrastructure in the 21st century. The outpouring of suggested reforms that have followed in the wake of Enron and WorldCom have focused on federal law and on the conduct of officers and directors, rather than state law, which in practice, focuses mainly on directors. Indeed, the discussions about reforms have excluded state law almost entirely. In this article, we develop the idea of federal law as corporate governance in three parts organized around history, empirical data, and analysis. In Part I, we begin with the traditional legal template. State corporate law is the focus and federal securities law plays a supporting role. In Part II, we present empirical data on the use of both federal and state litigation to regulate corporate governance. We begin with a data set we have developed of securities fraud class action complaints filed in 1999. Our analysis of those complaints shows that securities fraud class action litigation is being used mostly in areas that relate to the managers' operation of the business. Not surprisingly, for example, many of the complaints raise concerns about the ways in which managers have recognized re
通过证券欺诈集体诉讼的联邦证券法和执法今天已经成为监管公司治理的最明显的存在。长期处于公司治理讨论中心位置的州法,继续为公司形式提供法律框架,州信托责任诉讼继续作为监督经理的常用手段。然而,在当今世界,州法几乎完全是在有关收购或自营交易的决定的特定背景下这样做的。本文中的经验证据表明,这些领域之外的公司治理已经转移到联邦法律,特别是根据规则10b-5的股东诉讼。在当前的公司问责丑闻之后,国会通过了2002年的《萨班斯-奥克斯利法案》(Sarbanes-Oxley Act),为联邦法律的作用扩大提供了新的证据。但是,转向联邦公司治理的范围比该法律更广泛,而且比当前的丑闻历史更悠久。联邦法律在公司治理方面的优势至少反映了三个因素。首先,信息披露已成为监管公司经理的最重要方法,而且信息披露主要是联邦政府而非各州的方法。其次,州法律主要关注董事的职责和责任,而不是管理人员,联邦法律越来越多地占据了定义管理人员职责和责任的空间。管理人员已经成为当今公司治理的支点。第三,与基于信义义务的州股东诉讼相比,基于证券欺诈的联邦股东诉讼具有几个实际优势,这些优势有助于更多地利用联邦法院。由于这些趋势,联邦法律现在占据了21世纪法律公司治理基础设施的最大部分。在安然(Enron)和世通(WorldCom)事件之后,各方纷纷提出改革建议,重点关注的是联邦法律以及高管和董事的行为,而不是实际上主要针对董事的州法律。事实上,关于改革的讨论几乎完全排除了州法律。在本文中,我们将围绕历史、实证数据和分析三个部分来发展联邦法律作为公司治理的理念。在第一部分中,我们从传统的法律模板开始。州公司法是重点,联邦证券法起辅助作用。在第二部分中,我们提出了使用联邦和州诉讼来规范公司治理的实证数据。我们从1999年证券欺诈集体诉讼投诉的数据集开始。我们对这些投诉的分析表明,证券欺诈集体诉讼主要用于与经理经营业务相关的领域。例如,毫不奇怪,许多投诉引发了人们对管理人员确认收入或从事某种形式的会计操纵的方式的担忧。在此基础上,我们使用其他人开发的关于证券欺诈集体诉讼的更普遍的数据来扩展故事。然后,我们将导致证券欺诈索赔的交易与另一个数据集进行比较,该数据集涵盖了同年在特拉华州衡平法院提交的所有公司案件。其结果是,令人惊讶的是,对州诉讼的关注范围很窄,而对联邦诉讼的关注范围要广得多,这暴露出在公司治理的标准学习上存在差距。在第三部分中,我们讨论了我们提供的联邦证券欺诈图景如何与当前公司治理理论中的州股东诉讼相适应。

Officers have become the fulcrum of governance in today's corporations. Third, federal shareholder litigation based on securities fraud has several practical advantages over state shareholder litigation based on fiduciary duty that have contributed to the greater use of the federal forum. As a result of these trends, federal law now occupies the largest part of the legal corporate governance infrastructure in the 21st century. The outpouring of suggested reforms that have followed in the wake of Enron and WorldCom have focused on federal law and on the conduct of officers and directors, rather than state law, which in practice, focuses mainly on directors. Indeed, the discussions about reforms have excluded state law almost entirely. In this article, we develop the idea of federal law as corporate governance in three parts organized around history, empirical data, and analysis. In Part I, we begin with the traditional legal template. State corporate law is the focus and federal securities law plays a supporting role. In Part II, we present empirical data on the use of both federal and state litigation to regulate corporate governance. We begin with a data set we have developed of securities fraud class action complaints filed in 1999. Our analysis of those complaints shows that securities fraud class action litigation is being used mostly in areas that relate to the managers' operation of the business. Not surprisingly, for example, many of the complaints raise concerns about the ways in which managers have recognized re","PeriodicalId":340204,"journal":{"name":"Vanderbilt University Law School","volume":"56 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2002-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126603431","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}

Vertical Integration and Media Regulation in the New Economy 新经济中的垂直整合与媒体监管
Pub Date : 2002-07-16 DOI: 10.2139/SSRN.319122
C. S. Yoo
Recent mergers and academic commentary have placed renewed focus on what has long been one of the central issues in media policy: whether media conglomerates can use vertical integration to harm competition. This Article seeks to move past previous studies, which have explored limited aspects of this issue, and apply the full sweep of modern economic theory to evaluate the regulation of vertical integration in media-related industries. It does so initially by applying the basic static efficiency analyses of vertical integration developed under the Chicago and post-Chicago Schools of antitrust law and economics to three industries: broadcasting, cable television, and cable modem systems. An analysis of the market structure of these industries reveals that the preconditions recognized by both Schools as necessary for vertical integration to harm competition do not exist. In addition, the cost structure of these industries suggests that vertical integration may well lead to efficiencies sufficient to justify allowing such integration to occur. A dynamic efficiency analysis also suggests that attempts to regulate vertical integration in these industries are probably misguided. Growing reliance on compelled access to redress the problems purportedly caused by vertical integration threatens to dampen investment incentives in technologically dynamic industries in which such incentives are particularly important. Not only does forcing a monopolist to share an input deviate from the system of well-defined property rights needed to promote efficient levels of investment, it also deprives new entrants seeking to compete directly with the supposed monopoly bottleneck of their natural strategic partners. The Article also engages a complex web of arguments involving the extent to which technological innovation is affected by market concentration, standardization, and network externalities. A close review of the economic literature reveals that the relationship between these factors is too ambiguous to support the type of simple policy inference needed to prohibit vertical integration as a regulatory matter. The Article concludes with an analysis of the intellectual and institutional obstacles for adopting a more integrated economic approach to vertical integration in these industries.
最近的并购和学术评论重新将焦点放在了媒体政策长期以来的核心问题之一:媒体集团是否可以利用垂直整合损害竞争。本文试图超越以往的研究,这些研究只探讨了这个问题的有限方面,并运用现代经济理论的全面范围来评估媒体相关行业的垂直整合监管。本文首先将芝加哥学派和后芝加哥学派的反托拉斯法和经济学发展起来的垂直整合的基本静态效率分析应用于三个行业:广播、有线电视和有线调制解调器系统。对这些行业市场结构的分析表明,两派认为垂直整合损害竞争所必需的先决条件并不存在。此外,这些行业的成本结构表明,垂直整合很可能带来足够的效率,足以证明允许这种整合发生是合理的。一项动态效率分析也表明,试图规范这些行业的垂直整合可能是错误的。越来越多地依靠强迫进入来解决据称由垂直一体化造成的问题,这可能会削弱对技术上有活力的工业的投资奖励,而这种奖励在这些工业中是特别重要的。强迫垄断者分享投入不仅偏离了提高投资效率所需的明确界定的产权制度,而且还剥夺了寻求与天然战略伙伴的所谓垄断瓶颈直接竞争的新进入者。这篇文章还涉及了一系列复杂的争论,包括技术创新在多大程度上受到市场集中度、标准化和网络外部性的影响。对经济文献的仔细审查表明,这些因素之间的关系过于模糊,无法支持将禁止垂直一体化作为监管事项所需的简单政策推断。文章最后分析了在这些行业采用更综合的经济方法进行垂直整合的智力和制度障碍。

Realigning Corporate Governance: Shareholder Activism by Labor Unions 重组公司治理:工会的股东行动主义
Pub Date : 1993-04-01 DOI: 10.2139/SSRN.1729348
Stewart J. Schwab, Randall S. Thomas
Labor unions are aggressively using their ownership power to push corporate-governance reforms. So far, much of their activity is tactical. Lasting changes in corporate governance can occur if unions develop a more strategic model of their role in corporate governance. A stretegic model would require unions to concentrate on areas where their interests coincide with other shareholders and where they can demonstrte that their actions will increase firm value. This requires that labor unions adopt a platform of maximizing long-term growth for shareholders and other stakeholders, as well as for themselves. In particular, unions must convince other shareholders that they are acting in areas where they have an informational advantage about the corporation's and management's operations. If labor can demonstrate to other sharholders that it is using its monitoring advantagaes to take actions to increase firm value by policing management shirking and reducing the agency costs of equity, then other shareholders will be more willing to follow its lead in future voting initiatives. This opens up the possibility that labor union shareholders could reinvigorate some currently ineffectual corporate-governance systems. These might include the policing of securities fraud and other types of corporate misconduct through the use of existing litigation techniques.
工会正积极利用其所有权推动公司治理改革。到目前为止,他们的大部分活动都是战术性的。如果工会发展出一种更具战略性的公司治理模式,公司治理就会发生持久的变化。一个战略模式将要求工会专注于他们与其他股东利益一致的领域,以及他们能够证明自己的行动将增加公司价值的领域。这就要求工会采取一个为股东和其他利益相关者以及工会自身实现长期增长最大化的平台。特别是,工会必须让其他股东相信,他们在公司和管理层运作方面拥有信息优势。如果工会能够向其他股东证明,它正在利用其监督优势采取行动,通过监管管理层的逃避行为和降低股权的代理成本来增加公司价值,那么其他股东将更愿意在未来的投票倡议中跟随它的领导。因此,工会股东有可能重新激活目前一些无效的公司治理体系。这些可能包括通过使用现有的诉讼技术来监管证券欺诈和其他类型的公司不当行为。
