This paper studies references to case law in merger control decisions by the EC Directorate General for Competition (DG COMP) in 1990–2022. I use the full set of references to Court of Justice of the European Union (CJEU) judgments in DG COMP decisions to examine implementation, industry dynamics and effects of the 2004 merger control reform. New case law is shown to be immediately incorporated into the merger control practice without a learning period, subsequent citations correlate with industry-specific merger activity and the 2004 ECMR reform changed which judgments are frequently cited. European merger control should thus be viewed as a dynamic framework rather than constant in time and across industries. When controlling for quantifiable determinants of case law citations, the ceteris paribus relevance of case law is constant for 20–25 years, implying that judgments do not intrinsically lose relevance over time.
本文研究了 1990-2022 年欧盟竞争总司(DG COMP)在兼并控制决策中对判例法的引用。我利用竞争总司决策中对欧盟法院判决的全套引用来研究 2004 年兼并控制改革的实施、行业动态和效果。结果表明,新判例法无需学习期即可立即融入兼并控制实践,随后的引用与特定行业的兼并活动相关,而 2004 年的欧盟兼并控制改革改变了哪些判决被频繁引用。因此,欧洲兼并控制应被视为一个动态框架,而不是在时间上和行业间保持不变。在控制判例法引用的可量化决定因素时,判例法的比照相关性在 20-25 年间保持不变,这意味着判决并不会随着时间的推移而失去其固有的相关性。

Jury priors and observable defendant characteristics 陪审团先验和可观察的被告特征
IF 0.9 3区 社会学 Q3 ECONOMICS Pub Date : 2025-03-01 Epub Date: 2025-01-06 DOI: 10.1016/j.irle.2025.106245

Although prohibited, jurors sometimes condition, consciously or subconsciously, their belief that a defendant is guilty on the defendant’s race or ethnicity or other observable characteristics. This can be viewed as a juror forming a prior or pre-trial/evidence disclosure belief of guilt. In doing this, they rely on their perceptions of education, socio-economic status, religion, beliefs, networks, etc. for the defendant’s race (or other observable characteristic) and how they perceive those to influence the probability the defendant is guilty. This is consistent with aversive discrimination, which suggests that people want to be egalitarian and not condition on race but have a tendency to base decisions on factors that are discriminatory when race is not salient. When this prior or pre-trial/evidence disclosure belief of guilt overestimates the prior probability of guilt for those in the minority group, it underestimates the prior probability of guilt for those in the majority group. Prohibiting conditioning on observable defendant characteristics can be viewed as requiring the use of the population prior/pre-trial probability of guilt. Conditions for when such prohibition improves accuracy are provided. While it is difficult to effectively prohibit this, studies of aversive discrimination suggest that making race salient in a trial can reduce implicit bias on race. So these results may provide some guidance on when such activity should be permitted.
虽然被禁止,但陪审员有时会有意识或潜意识地以被告的种族或其他可观察到的特征来决定他们对被告有罪的信念。这可以被视为陪审员形成事先或审前/证据披露的有罪信念。在这样做的过程中,他们依靠他们对被告种族(或其他可观察到的特征)的教育、社会经济地位、宗教、信仰、网络等的看法,以及他们如何看待这些因素来影响被告有罪的可能性。这与厌恶歧视是一致的,这表明人们想要平等,不以种族为条件,但当种族不突出时,人们倾向于基于歧视性因素做出决定。当这种先前或审判前/证据披露的有罪信念高估了少数群体的有罪先验概率时,它低估了多数群体的有罪先验概率。禁止对可观察到的被告特征施加条件可以被视为要求使用人口在先/审前有罪概率。提供了这种禁止何时提高准确性的条件。虽然很难有效地禁止这种情况,但对厌恶歧视的研究表明,在试验中突出种族可以减少对种族的隐性偏见。因此,这些结果可能为何时允许此类活动提供一些指导。

An inspector calls: On the optimality of warning firms about ongoing inspections in antitrust policy 一名检查员呼吁:在反垄断政策中警告公司正在进行的检查的最优性

This paper investigates the effects of disclosing information about the likelihood of an inspection on the sustainability of cartels. To this end, I develop a model in which the Antitrust Authority can credibly disclose this type of information before firms make strategic decisions. In this way, the Antitrust Authority can distort the optimal behavior of the cartel firms related to production and cartel activities between inspection periods and non-inspection periods. I show how this can destabilize some cartel agreements, but it can also create productive inefficiencies not considered in standard models of collusion, to the extent that it induces cartel firms to devote costly resources to cartel activities.
本文研究了披露有关检查可能性的信息对卡特尔可持续性的影响。为此,我开发了一个模型,在这个模型中,反垄断机构可以在企业做出战略决策之前可靠地披露这类信息。通过这种方式,反垄断机构可以扭曲卡特尔企业在检查期和非检查期之间与生产和卡特尔活动相关的最优行为。我展示了这会如何破坏一些卡特尔协议的稳定,但它也会造成标准共谋模型中没有考虑到的生产效率低下,以至于它诱使卡特尔公司将昂贵的资源投入到卡特尔活动中。

Allocating the common costs of a public service operator: An axiomatic approach 公共服务经营者的公共成本分配:一种公理方法
IF 0.9 3区 社会学 Q3 ECONOMICS Pub Date : 2025-03-01 Epub Date: 2025-02-03 DOI: 10.1016/j.irle.2025.106247

Accurate cost allocation is a challenge for both public service operators and regulatory bodies, given the dual objectives of ensuring essential public service provision and maintaining fair competition. Operators have the obligation to provide essential public services for all individuals, which may incur additional costs. To compensate this, the operators receive state aids, which are determined by an assessment of the net cost associated with these obligations. However, these aids introduce the risk of distorting competition, as operators may employ them to subsidize competitive activities. To avoid this risk, a precise cost allocation method that adequately assess the net cost of these obligations becomes necessary. Such a method must satisfy specific properties that effectively prevent cross-subsidization. In this paper, we propose a method grounded in cooperative game theory that offers a solution for allocating common costs between activities and obligations in public service provision. We adopt a normative approach by introducing a set of desirable axioms that prevent cross-subsidization. We provide two characterizations of our proposed solution on the basis of these axioms. Furthermore, we present an illustration of our method to the allocation of common costs for a public service operator.
鉴于确保提供基本公共服务和维持公平竞争的双重目标,准确的成本分配对公共服务经营者和监管机构都是一项挑战。运营商有义务为所有人提供基本的公共服务,这可能会产生额外的费用。为了弥补这一点,运营商获得国家援助,这是由与这些义务相关的净成本评估确定的。然而,这些辅助措施带来了扭曲竞争的风险,因为运营商可能会利用它们来补贴竞争活动。为了避免这种风险,必须采用一种精确的费用分配方法,充分评估这些债务的净费用。这种方法必须满足有效防止交叉补贴的特定性质。在本文中,我们提出了一种基于合作博弈论的方法,该方法为公共服务提供中的活动和义务之间的共同成本分配提供了解决方案。我们采用了一种规范的方法,引入了一套防止交叉补贴的理想公理。我们在这些公理的基础上给出了我们提出的解决方案的两个特征。此外,我们还展示了我们的方法来分配公共服务运营商的共同成本。

Norms as obligations 作为义务的规范
IF 0.9 3区 社会学 Q3 ECONOMICS Pub Date : 2025-03-01 Epub Date: 2024-11-26 DOI: 10.1016/j.irle.2024.106235

Economists model legal compliance as the process of maximizing utility while weighing the consequences from norm violation against other (monetary and non-monetary) considerations. Legal philosophers, on the other hand, believe that the normative side of law is central. Citizens comply because they have an obligation to do so. Legal norms provide exclusionary reasons that prevent weighing up on other issues. We test and compare both models in a controlled online experiment. We conduct a modified dictator game with partially unknown yet ascertainable payoffs, and vary between treatments the presence and content of authoritative norms. Our experimental results show that – in the presence of a norm – participants follow norms without searching for information that they deem important in the absence of a norm. This pattern is independent of the specific content of the norm. Our results are consistent with the legal model of norm compliance.
经济学家将遵守法律视为效用最大化的过程,同时将违反规范的后果与其他(货币和非货币)考虑因素进行权衡。而法律哲学家则认为,法律的规范性是核心。公民遵守法律是因为他们有义务这样做。法律规范提供了排除性的理由,阻止了对其他问题的权衡。我们在一个受控在线实验中测试并比较了这两种模式。我们进行了一个改良的独裁者博弈,博弈中的报酬部分未知,但可以确定,并且在不同的处理中,权威性规范的存在和内容会有所不同。我们的实验结果表明,在有规范的情况下,参与者会遵守规范,而不会搜索他们在没有规范的情况下认为重要的信息。这种模式与规范的具体内容无关。我们的结果与遵守规范的法律模型是一致的。

ESG disclosure, investor awareness, and carbon risk pricing: Evidence from the Chinese market ESG信息披露、投资者意识和碳风险定价:来自中国市场的证据
IF 0.9 3区 社会学 Q3 ECONOMICS Pub Date : 2024-12-01 Epub Date: 2024-07-25 DOI: 10.1016/j.irle.2024.106217

This article examines the relationship between carbon disclosure, equity returns, and investor awareness in the Chinese A-share market. The study uses firm-disclosed and proprietary vendor-estimated carbon emissions data for A-share listed companies and investigates whether the presentation of carbon risks affects the cross-sectional equity returns of Chinese domestically listed firms. The results indicate that main-board listed companies with higher unscaled carbon emissions tend to earn higher equity returns, even after controlling for factors such as size, book-to-market ratio, momentum, and firm characteristics. Moreover, the observed carbon risk premium associated with carbon-emitting companies decreases as investor awareness improves following the launch of policy agendas promoting carbon neutrality in China. These findings support the research hypothesis that investors seek higher returns for equity investments in carbon-emission-intensive companies to compensate for the higher carbon risks associated with such firms. The study also highlights the importance of carbon disclosure, as companies generally disclose their ESG information when they have improved performance in reducing their carbon emissions.

本文探讨了中国 A 股市场碳信息披露、股票收益和投资者意识之间的关系。研究利用公司披露的碳排放数据和专有供应商估算的碳排放数据,考察了碳风险的表述是否会影响中国国内上市公司的横截面股票回报。结果表明,即使在控制了规模、市净率、发展势头和公司特征等因素后,无标度碳排放量较高的主板上市公司也倾向于获得较高的股票回报。此外,在中国推出促进碳中和的政策议程后,随着投资者意识的提高,观察到的与碳排放公司相关的碳风险溢价也会降低。这些发现支持了研究假设,即投资者在碳排放密集型公司的股权投资中寻求更高的回报,以补偿这类公司相关的较高碳风险。该研究还强调了碳信息披露的重要性,因为公司一般会在其碳减排业绩有所改善时披露其 ESG 信息。

The broken-windows theory of crime: A Bayesian approach 破窗犯罪理论:贝叶斯方法

The broken-windows theory of crime is based on the idea that aggressive enforcement of petty crimes, like misdemeanors, will have a deterring effect on would-be perpetrators of more serious crimes. This paper develops a model of this theory that depends on three factors: (1) potential offenders make decisions about committing crimes based on their beliefs about the probability of apprehension; (2) those beliefs depend on prior observations or knowledge about the rate of petty crimes; and (3) there is a linkage across criminal categories (minor vs. serious crimes) as a component of actual enforcement policy. Our results show that even if these factors are all present, increased enforcement of low-harm crimes does not necessarily lead to fewer high-harm crimes.
犯罪 "破窗理论 "的理论基础是,对轻罪等轻微犯罪积极执法,会对可能犯下更严重罪行的人产生威慑作用。本文为这一理论建立了一个模型,该模型取决于三个因素:(1) 潜在罪犯根据他们对被捕概率的信念做出犯罪决定;(2) 这些信念取决于先前对轻罪犯罪率的观察或了解;(3) 作为实际执法政策的一部分,不同犯罪类别(轻罪与重罪)之间存在联系。我们的结果表明,即使这些因素都存在,加强对低危害性犯罪的执法也不一定会导致高危害性犯罪的减少。

Estimating the effect of concealed carry laws on murder: A response to Bondy, et al. 估计隐蔽携带枪支法对谋杀案的影响:对邦迪等人的回应
IF 0.9 3区 社会学 Q3 ECONOMICS Pub Date : 2024-12-01 Epub Date: 2024-11-13 DOI: 10.1016/j.irle.2024.106234

In 2021 we wrote a short paper noting that truncating the sample when estimating the effect of right to carry laws on crime could be biased by comparisons to states that already adopted the law, instead of states without the law. In 2023 Bondy et al. criticized our paper but inaccurately described what we did and provided selective and misleading results. More importantly, they completely missed the point of our analysis, namely that applying two-way fixed effects to a truncated sample, say 1991–2018, biases the resulting RTC coefficient by invalidly comparing newly treated states to 11 previously treated states. The bias is so large that even if the true coefficient on the right-to-carry dummy is negative, the estimated coefficient could be positive. These biased results can be corrected by using new DID estimators, that do not make invalid comparisons, and which are robust to time and state heterogeneity. Using these new estimators, we find that RTC laws do not significantly increase violent crime. We find evidence that RTC laws significantly reduce murder and that constitutional carry laws significantly reduce rape.
2021 年,我们撰写了一篇短文,指出在估算携带权法对犯罪的影响时,对样本进行截断,可能会因为与已通过该法律的州而非未通过该法律的州进行比较而产生偏差。2023 年,邦迪等人批评了我们的论文,但对我们所做工作的描述并不准确,并提供了选择性和误导性的结果。更重要的是,他们完全忽略了我们分析的重点,即对一个截断样本(如 1991-2018 年)应用双向固定效应,会使得出的 RTC 系数产生偏差,因为他们将新近接受治疗的州与之前接受治疗的 11 个州进行了无效比较。偏差如此之大,以至于即使携带权虚拟变量的真实系数为负,估计系数也可能为正。使用新的 DID 估计器可以纠正这些有偏差的结果,这种估计器不会进行无效比较,而且对时间和州异质性具有稳健性。利用这些新的估计方法,我们发现 RTC 法律并没有显著增加暴力犯罪。我们发现有证据表明,RTC 法律大大减少了谋杀案,而宪法规定的随身携带法律则大大减少了强奸案。

We use machine learning methods to predict which patents end up in court using the population of US patents granted between 2002 and 2005. We show that patent characteristics have significant predictive power, particularly value indicators and patent-owner characteristics. Furthermore, we analyze the predictive performance concerning the number of observations used to train the model, which patent characteristics to use, and which predictive model to choose. We find that extending the set of patent characteristics has the biggest positive impact on predictive performance. The model choice matters as well. More sophisticated machine learning methods provide additional value relative to a simple logistic regression. This result highlights the existence of non-linearities among and interactions across the predictors. Our results provide practical advice to anyone building patent litigation models, e.g., for litigation insurance or patent management more generally.

我们使用机器学习方法,以 2002 年至 2005 年间获得授权的美国专利为样本,预测哪些专利最终会被送上法庭。我们的研究表明,专利特征具有显著的预测能力,尤其是价值指标和专利所有人特征。此外,我们还分析了用于训练模型的观测数据的数量、使用哪种专利特征以及选择哪种预测模型等方面的预测性能。我们发现,扩展专利特征集对预测性能的积极影响最大。模型的选择也很重要。相对于简单的逻辑回归,更复杂的机器学习方法能提供更多价值。这一结果凸显了预测因素之间存在非线性和交互作用。我们的研究结果为任何建立专利诉讼模型的人提供了实用的建议,例如用于诉讼保险或更广泛的专利管理。

On the strategic choice of overconfident lawyers 关于过于自信的律师的战略选择
IF 0.9 3区 社会学 Q3 ECONOMICS Pub Date : 2024-12-01 Epub Date: 2024-09-12 DOI: 10.1016/j.irle.2024.106231

This paper analyzes how the plaintiff selects her lawyer based on lawyers’ confidence in their trial-effort productivity. The plaintiff’s lawyer works on a contingent fee and makes litigation decisions on the plaintiff’s behalf. When the lawyer’s preferences are decisive at both the settlement and the trial stage, the plaintiff must anticipate that a more confident lawyer evaluates settlement compared to trial differently and implies different equilibrium trial effort levels. When the lawyer implements the plaintiff’s ideal settlement demand, only the influence of the confidence level on trial effort levels is relevant. In both cases, the plaintiff prefers an overconfident lawyer but would be harmed by excessive overconfidence. In many circumstances, the optimal confidence level maximizes the plaintiff’s trial payoff. However, when the lawyer’s preferences are decisive at both the settlement and trial stage, the plaintiff may choose an even more confident lawyer to raise the settlement level her lawyer demands from the defendant.

本文分析了原告如何根据律师对其审判效率的信心来选择律师。原告律师以或有收费方式工作,并代表原告做出诉讼决定。当律师的偏好在和解和审判阶段都起决定性作用时,原告必须预见到,与审判相比,更自信的律师对和解的评价不同,这意味着不同的均衡审判努力水平。当律师执行原告的理想和解要求时,只有信心水平对审判努力水平的影响是相关的。在这两种情况下,原告都更喜欢过于自信的律师,但过度过度自信会损害原告的利益。在许多情况下,最佳信心水平会使原告的审判报酬最大化。然而,当律师的偏好在和解和审判阶段都起决定性作用时,原告可能会选择一名更加自信的律师,以提高其律师向被告要求的和解水平。
