This paper proposes an approach to guide statistical capacity building in developing countries using an analysis based on components of the World Bank’s Statistical Performance Indicator on a sample of 215 countries. The approach demonstrates the importance of expanding traditional capacity-building activities to include programs to strengthen and better monitor the ability of National Statistical Systems (NSS) to respond to user data needs. Based on this analysis, the paper recommends a two-step strategy for building and enhancing the statistical capacity of national statistical systems in developing countries. The strategy creates a sustainable trajectory for developing NSSs that meets the growing demands of local and global data users. The paper emphasizes the importance of donor coordination and South-South learning initiatives for international capacity-building efforts.
本文提出了一种指导发展中国家统计能力建设的方法,该方法基于对215个国家样本的世界银行统计绩效指标组成部分的分析。这种方法表明了扩大传统能力建设活动的重要性,包括加强和更好地监测国家统计系统响应用户数据需求的能力的方案。基于这一分析,本文建议了一个两步走的战略,以建立和加强发展中国家国家统计系统的统计能力。该战略为发展满足本地和全球数据用户日益增长的需求的国家安全设施创造了可持续的发展轨迹。该文件强调了捐助者协调和南南学习倡议对国际能力建设工作的重要性。

No Panic in Pandemic: The Impact of Individual Choice on Public Health Policy and Vaccine Priority 大流行中没有恐慌:个人选择对公共卫生政策和疫苗优先级的影响
Pub Date : 2021-01-10 DOI: 10.2139/ssrn.3763514

Infectious disease outbreaks such as COVID-19 pose significant public health threats and challenges worldwide due to their high transmissibility and potentially severe symptoms and complications. Although public health interventions such as social distancing and lockdown can slow the disease spread, the disruption to regular economic and social activities caused by these interventions have caused significant financial losses. Strategic planning is required to optimize the timing and intensity of these public health interventions by considering individual response. We derive insightful structural properties of the optimal public health interventions and conduct numerical studies based on representative COVID-19 data in Minnesota. We find that the individual equilibrium activity level is higher than the socially optimal activity level due to an individual’s ignorance of the negative externality imposed on others, with the largest difference at a middle-range disease prevalence. As a result, lockdowns and social distancing policies are more effective when the disease prevalence is not at its peak level. Social distancing is more effective than lockdowns based on the representative COVID-19 data from Minnesota. Moreover, due to the limited vaccine capacity, vaccination priority strategy needs to consider the trade-off between the higher mortality rate of the less active group and the higher negative externality imposed by the more active group. Changes in vaccine production capacity, mortality rate ratio and infection rate may affect vaccination priorities. Lastly, while the vaccine priority to the elderly group is most effective in reducing total deaths, it has to be accompanied with more stringent social distancing policies.
COVID-19等传染病暴发由于其高传播性和潜在的严重症状和并发症,在全球范围内构成重大的公共卫生威胁和挑战。虽然保持社交距离和封锁等公共卫生干预措施可以减缓疾病的传播,但这些干预措施对正常经济和社会活动造成的破坏造成了重大的经济损失。需要进行战略规划,通过考虑个人应对措施,优化这些公共卫生干预措施的时机和强度。我们得出了最优公共卫生干预措施的深刻结构特征,并基于明尼苏达州具有代表性的COVID-19数据进行了数值研究。我们发现,由于个体对强加于他人的负外部性的无知,个体均衡活动水平高于社会最优活动水平,在中等范围的疾病患病率上差异最大。因此,在疫情未达到高峰时,封锁和保持社会距离政策更为有效。根据明尼苏达州的代表性COVID-19数据,社交距离比封锁更有效。此外,由于疫苗容量有限,疫苗接种优先策略需要考虑较不活跃群体较高的死亡率与较活跃群体较高的负外部性之间的权衡。疫苗生产能力、死亡率和感染率的变化可能影响疫苗接种的优先次序。最后,虽然以老年人群体为重点的疫苗在减少总死亡人数方面最有效,但它必须伴随着更严格的社会距离政策。

Merger Breakups 合并分手
Pub Date : 2020-11-18 DOI: 10.2139/ssrn.3469984
Menesh S. Patel
One of today’s most pressing antitrust questions is how antitrust should address the conduct of dominant technology companies. Once considered untouchable by antitrust law, these technology behemoths are now the subject of growing calls for antitrust breakup, including through actions by the federal antitrust agencies to challenge and unwind key mergers in the technology space. But nearly every one of the technology mergers identified for ex post challenge and breakup was previously reviewed and cleared by the antitrust agencies pursuant to the existing federal merger review scheme, even after a lengthy investigation in some instances. The calls for the antitrust breakup of these identified technology mergers therefore implicate a much more fundamental antitrust question: should the antitrust agencies more readily challenge mergers that they themselves previously reviewed and cleared pursuant to the existing federal merger review scheme? This Article offers a qualified affirmative response to that question. The antitrust agencies should increase the extent of their challenges to previously reviewed and cleared mergers but should do so in a principled way that respects the significant mitigating factors associated with an expansion in such ex post merger challenges. By conducting that principled analysis, this Article identifies important limiting conditions on the expansion of agency challenges to previously reviewed and cleared mergers.
当今最紧迫的反垄断问题之一是,反垄断应如何应对占主导地位的科技公司的行为。这些科技巨头曾被认为是反垄断法无法触及的对象,但如今,要求拆分反垄断的呼声越来越高,包括联邦反垄断机构采取行动,挑战和解除科技领域的关键合并。但是,几乎每一个被认定为事后挑战和拆分的技术合并都是事先由反垄断机构根据现有的联邦合并审查计划进行审查和批准的,即使在某些情况下经过了漫长的调查。因此,要求对这些已确定的技术合并进行反垄断拆分的呼声隐含了一个更为根本的反垄断问题:反垄断机构是否应该更容易地挑战它们自己先前根据现有的联邦合并审查计划审查并批准的合并?本文对这个问题作出了有条件的肯定答复。反垄断机构应增加对先前审查和批准的合并的挑战程度,但应以一种原则性的方式进行,尊重与此类合并后挑战扩张相关的重大缓解因素。通过进行原则性分析,本文确定了机构挑战扩大到先前审查和清除的合并的重要限制条件。

Guidance Documents: The Sirens of the Cannabis Odyssey 指导文件:大麻奥德赛的塞壬
Pub Date : 2020-11-13 DOI: 10.2139/ssrn.3754530
T. Sims
The growing cannabis industry in the United States has presented both economic opportunity and legal complexity. States that allow medical or recreational cannabis conflict with federal regulations and lawyers who represent cannabis businesses are caught in an ethical maze. This article discusses an often-overlooked cause of this complexity: guidance documents from the Department of Justice. The rapid growth of the cannabis industry correlates with a series of memos issued by the Department of Justice, one of which is known as the “Cole Memorandum”, and all of which have been rescinded. The ambiguities and shortcomings of current administrative law have played a large part in creating the confusing legal status of the cannabis industry. Resolutions must reflect this reality to adequately address the ethical, financial, and legal problems in the cannabis industry.
美国不断增长的大麻产业既带来了经济机会,也带来了法律复杂性。允许医用或娱乐用大麻的州与联邦法规发生冲突,代表大麻企业的律师陷入了道德迷宫。本文讨论了导致这种复杂性的一个经常被忽视的原因:司法部的指导文件。大麻产业的快速发展与司法部发布的一系列备忘录有关,其中一份被称为“科尔备忘录”,所有这些备忘录都已被废除。现行行政法的含糊不清和缺陷在造成大麻工业令人困惑的法律地位方面发挥了很大作用。决议必须反映这一现实,以充分解决大麻产业的道德、财政和法律问题。

Do Firms Experiencing More Wildfires Disclose More Wildfire Information in Their 10-Ks? 经历更多野火的公司在10- k中披露了更多野火信息吗?
Pub Date : 2020-08-31 DOI: 10.2139/ssrn.3683551

Wildfires pose a significant risk that threatens firm value. That risk may have risen significantly in recent years in light of record-breaking wildfires in the United States and elsewhere. It is an open question, however, whether such increasing wildfire risk affects firms’ disclosures of wildfire-related information. We match the location of wildfires in the United States to firms with headquarters in the same county as the wildfire. We find that firms exposed to more wildfire days on average provide more textual 10-K disclosure of wildfire-related information in their filings compared to firms exposed to fewer wildfire days. Our results are also significant economically. For example, an increase of wildfire days from zero to one day increases 10-K wildfire word count by 30 percent. We attribute this positive relation to increasing trends in climate change risks and disclosure guidance related to heightened wildfire concerns. These concerns emanate mainly from wildfire-exposed firms in the western states, in the utility and banking industries, those exhibiting a high level of tangible assets, and those having experienced wildfire impacting their past operations. Overall, the findings deepen our knowledge of a heretofore unstudied risk factor important for firm value.
野火构成了威胁公司价值的重大风险。近年来,鉴于美国和其他地方破纪录的野火,这种风险可能大大增加。然而,不断增加的野火风险是否会影响公司对野火相关信息的披露,这是一个悬而未决的问题。我们将美国发生野火的地点与总部位于野火发生地同一县的公司进行比对。我们发现,与遭遇较少野火天数的公司相比,遭遇更多野火天数的公司平均在其文件中提供更多野火相关信息的文本10-K披露。我们的成果在经济上也很重要。例如,将野火天数从零增加到一天,10-K野火字数将增加30%。我们将这种正相关关系归因于气候变化风险的增加趋势和与野火担忧加剧相关的披露指南。这些担忧主要来自于西部各州的公用事业和银行业中那些暴露于野火的公司,这些公司展示了高水平的有形资产,以及那些经历过野火影响其过去运营的公司。总的来说,这些发现加深了我们对迄今为止尚未研究的对公司价值重要的风险因素的认识。

Instrument Validity for Heterogeneous Causal Effects 异质性因果效应的工具效度
Pub Date : 2020-08-31 DOI: 10.2139/ssrn.3686562
Zhenting Sun
This paper provides a general framework for testing instrument validity in heterogeneous causal effect models. We first generalize the testable implications of the instrument validity assumption provided by Balke and Pearl (1997), Imbens and Rubin (1997), and Heckman and Vytlacil (2005). The generalization involves the cases where the treatment can be multivalued (and ordered) or unordered, and there can be conditioning covariates. Based on these testable implications, we propose a nonparametric test which is proved to be asymptotically size controlled and consistent. Because of the nonstandard nature of the problem in question, the test statistic is constructed based on a nonsmooth map, which causes technical complications. We provide an extended continuous mapping theorem and an extended delta method, which may be of independent interest, to establish the asymptotic distribution of the test statistic under null. We then extend the bootstrap method proposed by Fang and Santos (2018) to approximate this asymptotic distribution and construct a critical value for the test. Compared to the test proposed by Kitagawa (2015), our test can be applied in more general settings and may achieve power improvement. Evidence that the test performs well on finite samples is provided via simulations. We revisit the empirical study of Card (1993) and use their data to demonstrate application of the proposed test in practice. We show that a valid instrument for a multivalued treatment may not remain valid if the treatment is coarsened.
本文提供了一个在异质性因果效应模型中检验工具效度的一般框架。我们首先概括了Balke和Pearl(1997)、Imbens和Rubin(1997)以及Heckman和Vytlacil(2005)提出的工具效度假设的可测试含义。泛化涉及处理可以是多值(和有序)或无序的情况,并且可以存在条件协变量。基于这些可检验的意义,我们提出了一个非参数检验,证明了它是渐近大小控制和一致的。由于所讨论问题的非标准性质,测试统计量是基于非光滑映射构建的,这会导致技术上的复杂性。我们提供了一个扩展的连续映射定理和一个扩展的delta方法,这可能是独立的兴趣,以建立检验统计量在零下的渐近分布。然后,我们扩展了Fang和Santos(2018)提出的bootstrap方法来近似这个渐近分布,并为检验构造一个临界值。与Kitagawa(2015)提出的测试相比,我们的测试可以应用于更一般的设置,并可能实现功率改进。仿真结果表明,该方法在有限样本条件下性能良好。我们重新审视Card(1993)的实证研究,并使用他们的数据来证明所提出的测试在实践中的应用。我们表明,如果治疗变得粗糙,多值治疗的有效工具可能不再有效。

We show that a valid instrument for a multivalued treatment may not remain valid if the treatment is coarsened.","PeriodicalId":83406,"journal":{"name":"University of California, Davis law review","volume":"24 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87237997","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}

Mapping the Intellectual Property/Social Justice Frontier 绘制知识产权/社会正义前沿
Pub Date : 2020-07-22 DOI: 10.2139/ssrn.3658767
Peter S. Menell
This chapter explores the interplay of intellectual property and social justice. Part I constructs a philosophical framework for thinking about the many cross-currents between intellectual property and social justice. Part II distinguishes between the internal, largely utilitarian analysis of particular modes of intellectual property protection and the external interplay of intellectual property systems and broader social justice concerns. Part III examines the macro interplay of intellectual property and inequality, gender and racial inclusion, and global justice challenges, highlighting complexities, tensions, and paradoxes. The chapter considers how intellectual property law and policy can be seen not just as an engine of economic progress, but also as an engine of human and cultural flourishing, dignitary values, access, inclusion, and empowerment.
本章探讨知识产权与社会正义的相互作用。第一部分为思考知识产权与社会正义之间的诸多交叉趋势构建了一个哲学框架。第二部分区分了知识产权保护特定模式的内部,主要是功利主义分析和知识产权制度与更广泛的社会正义问题的外部相互作用。第三部分考察了知识产权与不平等、性别和种族包容以及全球正义挑战之间的宏观相互作用,突出了复杂性、紧张关系和悖论。本章探讨了知识产权法律和政策如何不仅被视为经济进步的引擎,而且被视为人类和文化繁荣、尊严价值观、获取、包容和赋权的引擎。

Supremacy of the Constitution: The Constitutionality of International Business Transactions Involving the Government of Ghana 宪法至上:涉及加纳政府的国际商业交易的合宪性
Pub Date : 2020-07-21 DOI: 10.2139/ssrn.3657344
Reginald Nii Odoi
Ghana has over the years developed into a world player with its Government engaging in all kinds of international business and economic transactions with foreign partners. All the same, Ghana being a sovereign nation does not act in a vacuum. All its actions must be done in line and in accordance with the laws of the country specifically the Constitution.

It is without doubt that Ghana’s Constitution reigns Supreme and is not superseded by any other law, act, etc be it domestic or international. Over the years, these international transactions entered into by the Government of Ghana and other international partners have ended up before the Courts of Ghana where the Courts in upholding the Supremacy of the Constitution have held that all these transactions being contracts involving the Government of Ghana are in a certain class which thus demands compliance with certain laid down requirements in the Constitution failure of which grave consequences have been suffered by these international partners.

It is thus necessary to consider the decisions in the light of Ghana’s Constitutional Supremacy, to sift out the road-maps as set out by the Courts of Ghana in order that Legal Advisers to foreign entities that contract with the Government of Ghana are aware of these important case laws in order to guide them appropriately on the Ghanaian law on this issue.
加纳多年来已发展成为一个世界参与者,其政府与外国伙伴进行各种国际商业和经济交易。尽管如此,加纳作为一个主权国家并不是在真空中行动。它的一切行动都必须符合和符合国家的法律,特别是宪法。毫无疑问,加纳宪法是至高无上的,不被任何其他法律、法令等所取代,无论是国内的还是国际的。这么多年来,加纳政府和其他国际伙伴签订的这些国际交易最终都在加纳法院结束,法院在维护宪法至上原则的情况下裁定,所有这些交易都是涉及加纳政府的合同,属于某一类,因此需要遵守《宪法》中规定的某些要求,否则这些国际伙伴将遭受严重后果。因此,有必要根据加纳宪法至上原则来审议这些决定,筛选加纳法院制定的路线图,以便与加纳政府签订合同的外国实体的法律顾问了解这些重要的判例法,以便适当地指导他们了解关于这个问题的加纳法律。
