When making a location decision, a firm considers only its own trading costs and ignores trading costs paid by trading partner firms. The exclusion of the latter is the source of locational externalities. We examine this locational externality in the Tokyo metropolitan area, using the actual trade networks. Results show (1) we classify what trade patterns involve locational externalities, (2) the ratio of trades involving locational externalities is about 8%, and (3) the transfer of a randomly-chosen 5% of firms to the center of Tokyo can generate external benefits of 0.13-0.21% in the total industry in terms of value added.
企业在进行选址决策时,往往只考虑自身的贸易成本,而忽略了贸易伙伴企业支付的贸易成本。后者的排除是区位外部性的根源。我们使用实际的贸易网络来研究东京大都市区的区位外部性。结果表明:(1)我们对涉及区位外部性的贸易模式进行了分类;(2)涉及区位外部性的贸易比例约为8%;(3)随机选择5%的企业向东京中心转移,可产生的增加值在全产业中的外部效益为0.13-0.21%。

The general trend away from traditional, formal insolvency proceedings opens up a vast area to private ordering, with all the associated opportunities and risks. The transition can be less costly if the resulting uncertainty is reduced to a minimum. This presents national legislators with a delicate challenge. They should not be overly prescriptive and should effectively delegate decision-making to stakeholders and expert professionals, who are likely to be better informed and better incentivised. At the same time, the law must provide for information to flow where needed and for the creation of optimal incentives. Against this background, guidance on best practices can be of great value. It may assist policymaking in one jurisdiction by drawing attention to successes and failures in others, and it may allow professionals, advisors, debtors, creditors and courts to find common ground in the formulation of high-quality distress resolution plans and in distinguishing viable and non-viable distressed debtors. Based on extensive empirical research in four European Union states, this book takes up the challenge of unearthing and crystallising some of the most critical best practices in the various stages of a distress resolution process. Drawing on these best practices, it provides lawmakers with several ‘Policy Recommendations’, and other key stakeholders with a set of ‘Guidelines’. Of particular interest will be development of a relative priority rule (recently recommended by the European Council for incorporation in the draft directive on preventive restructuring); and discussion of the utility of a duty to file versus one to avoid wrongful trading; crisis events and early warning indicators; fairness in plan formulation, voting, examination, and confirmation; class formation and ‘cram-down’ issues; the goals, contents, and structure of high-quality plans; the role of professional advisors; negotiation best practices; the impact of prudential rules on NPLs on banks’ behaviour in corporate workouts; and plan implementation and monitoring. Special attention is given to the particular needs of micro, small, and medium enterprises.
传统的、正式的破产程序逐渐消失的大趋势,为私人命令开辟了广阔的领域,带来了所有相关的机会和风险。如果由此产生的不确定性减少到最低限度,则转换的成本可以降低。这给国家立法者提出了一个微妙的挑战。它们不应过于规范,而应有效地将决策授权给利益相关者和专业人士,因为他们可能更了解情况,也更有动力。与此同时,法律必须规定信息在需要的地方流通,并制定最佳的奖励办法。在这种背景下,关于最佳实践的指导可能非常有价值。它可以通过提请注意其他司法管辖区的成功和失败来协助一个司法管辖区的决策,它可以使专业人员、顾问、债务人、债权人和法院在制定高质量的解决困境计划和区分可行和不可行的陷入困境的债务人方面找到共同点。基于对四个欧盟国家的广泛实证研究,本书提出了在解决困境过程的各个阶段挖掘和具体化一些最关键的最佳实践的挑战。根据这些最佳做法,它向立法者提供了几项“政策建议”,并向其他主要利益攸关方提供了一套“指导方针”。特别令人感兴趣的将是制定一项相对优先的规则(欧洲理事会最近建议将其纳入关于预防性改组的指令草案);讨论了申报义务与避免不当交易义务的效用;危机事件和预警指标;方案制定、表决、审查、确认的公正性;阶级形成和“压制”问题;高质量规划的目标、内容和结构;专业顾问的作用;谈判最佳做法;不良贷款审慎规则对银行在企业重组中的行为的影响;以及计划的实施和监控。特别注意微型、小型和中型企业的特殊需要。

When Less is More: Experimental Evidence on Information Delivery During India&Apos;S Demonetization 当少即是多:印度废钞运动期间信息传递的实验证据

In disseminating information, policymakers face a choice between broadcasting to everyone and informing a small number of “seeds” who then spread the message. While broadcasting maximizes the initial reach of messages, we offer theoretical and experimental evidence that it need not be the best strategy. In a field experiment during the 2016 Indian demonetization, we delivered policy information, varying three dimensions of the delivery method at the village level: initial reach (broadcasting versus seeding); whether or not we induced common knowledge of who was initially informed; and number of facts delivered. We measured three outcomes: the volume of conversations about demonetization, knowledge of demonetization rules, and choice quality in a strongly incentivized policy-dependent decision. On all three outcomes, under common knowledge, seeding dominates broadcasting; moreover, adding common knowledge makes seeding more effective but broadcasting less so. We interpret our results via a model of image concerns deterring engagement in social learning, and support this interpretation with evidence on differential behavior across ability categories.
在传播信息时,政策制定者面临着一个选择:是向所有人传播信息,还是通知少数“种子”,然后由他们传播信息。虽然广播最大化了信息的初始覆盖范围,但我们提供的理论和实验证据表明,它不一定是最好的策略。在2016年印度废钞运动期间的一项实地试验中,我们传递了政策信息,在村庄层面上改变了传递方法的三个维度:初始覆盖(广播与播种);我们是否诱导了谁最初被告知的常识;以及传递的事实数量。我们测量了三个结果:关于废除纸币的对话量,废除纸币规则的知识,以及在强烈激励的政策依赖决策中的选择质量。在所有三种结果中,在常识下,播种机主导广播;此外,常识的加入使播种更有效,而广播则不那么有效。我们通过一个形象顾虑阻碍社会学习参与的模型来解释我们的结果,并用不同能力类别的差异行为的证据来支持这一解释。

Primitives of Legal Protection in the Era of Data-Driven Platforms 数据驱动平台时代法律保护的基本要素
Pub Date : 2018-03-14 DOI: 10.2139/ssrn.3140594
M. Hildebrandt
In this essay I discuss the political economy of data driven platforms in terms of monopolies and monopsonies, arguing that the concentration of buying and selling power builds on and extends a pseudo-omniscient data architecture that feeds on an increasingly seamless data ecosystem. As the mathematical underpinnings of data driven architectures are further extended into the hardware of smart homes, driverless cars and smart cities, they may at some point diminish or eradicate the semantic discontinuity that provides room for dissent and dissonance. Such discontinuity depends on a text driven environment and affordances such as dissonance and adversariality cannot be taken for granted in the pervasive data ecosystem that drives the political economy of platforms. I contend that we need a small set of primitives of legal protection to shoot holes in the semantic continuity that is generated by the backend systems of data driven platforms; competition law, consumer law and tort law cannot contribute to the effective contestability of algorithmic decision-making all by themselves. They require effective and practical rights to data minimisation and purpose limitation and an actionable right not to be subject to automated decisions without a contestable justification. Once these primitives of legal protection are operational both the pseudo-omniscient nature of data architectures and the seamless nature of data ecosystems will be ruptured, thus reinstating the interstices for innovation, and for meaningful individual and political self-determination.
在这篇文章中,我从垄断和垄断的角度讨论了数据驱动平台的政治经济学,认为买卖权力的集中建立在并扩展了一种伪无所不知的数据架构,这种架构以日益无缝的数据生态系统为基础。随着数据驱动架构的数学基础进一步扩展到智能家居、无人驾驶汽车和智能城市的硬件中,它们可能会在某种程度上减少或消除为不同意见和不和谐提供空间的语义不连续性。这种不连续性取决于文本驱动的环境,而在驱动平台政治经济的无处不在的数据生态系统中,不和谐和对抗性等能力不能被视为理所当然。我认为,我们需要一组法律保护的原语来弥补数据驱动平台的后端系统所产生的语义连续性的漏洞;竞争法、消费者法和侵权法不能单独促进算法决策的有效可诉性。它们需要有效和实际的数据最小化和目的限制权利,以及在没有可争议的理由的情况下不受自动决策约束的可诉权利。一旦这些法律保护的基本要素开始运作,数据架构的伪全知性质和数据生态系统的无缝性质都将被打破,从而恢复创新的间隙,以及有意义的个人和政治自决。

Time-Consistent Monetary Policy, Terms of Trade Manipulation and Welfare in Open Economies 开放经济中的时间一致性货币政策、贸易条件操纵与福利
Pub Date : 2018-02-05 DOI: 10.2139/ssrn.3118957
Sebastian Schmidt
A key insight from the open economy literature is that domestic price stability is in general not optimal for countries that exert some market power over their terms of trade. Under commitment, a national benevolent monetary policymaker improves upon the allocation associated with stable domestic prices by manipulating the terms of trade to her own country’s advantage. In this paper, I study optimal monetary policy in a sticky-price small open economy model when the policymaker lacks a commitment device. Without commitment, the benevolent policymaker’s attempt to improve national welfare by manipulating the terms of trade can be self-defeating. By steering international relative prices the discretionary policymaker induces fluctuations in domestic prices, the costs of which she is unable to fully internalize in her decision-making. Society may thus be better off if it appoints an inward-looking policymaker who aims for domestic price stability and resists the temptation to exploit the country’s monopoly power in trade. Accounting for the effective lower bound on nominal interest rates further strengthens the case for the inward-looking policy objective. JEL Classification: E52, F41
开放经济文献的一个关键观点是,对于那些对其贸易条件施加一定市场力量的国家来说,国内价格稳定通常不是最佳的。在承诺下,一个仁慈的国家货币政策制定者通过操纵贸易条件,使其对本国有利,从而改善与稳定国内价格相关的分配。本文研究了政策制定者缺乏承诺机制时粘性价格小型开放经济模型下的最优货币政策问题。没有承诺,仁慈的政策制定者试图通过操纵贸易条件来提高国家福利的努力可能会弄巧成拙。通过操纵国际相对价格,自由裁量权的决策者引起了国内价格的波动,其成本无法在决策中充分内化。因此,如果任命一位着眼于国内价格稳定、抵制利用国家在贸易中的垄断力量的诱惑的内向型政策制定者,社会可能会变得更好。考虑到名义利率的有效下限,进一步强化了内向型政策目标的理由。JEL分类:E52, F41

Longterm Decision Making Under the Threat of Earthquakes 地震威胁下的长期决策
Pub Date : 2017-12-01 DOI: 10.2139/ssrn.3298413
Carmen Camacho, Yu Sun
Under the threat of earthquakes, long-term policy makers need tools to decide optimally on the economic trajectories that maximize the society welfare. Tools should be flexible and account for the consequences of earthquakes, incorporating the best estimate of their frequency and intensity. In this regard, we propose in this paper a modeling strategy that combines optimal control techniques and Bayesian learning: after an earthquake occurs, policy makers can improve their knowledge and adjust policies optimally. Two numerical examples illustrate the advantages of our modelling strategy along different dimensions. While Japan symbolizes the policy maker who has learned from earthquakes protecting the economy accordingly; Italy helps us illustrate the importance of prevention capital.
在地震的威胁下,长期政策制定者需要工具来最优地决定社会福利最大化的经济轨迹。工具应该是灵活的,并考虑到地震的后果,包括对地震频率和强度的最佳估计。为此,本文提出了一种将最优控制技术与贝叶斯学习相结合的建模策略:在地震发生后,决策者可以提高他们的知识水平并最优地调整政策。两个数值例子说明了我们的建模策略沿不同维度的优势。日本象征着从地震中吸取教训的决策者相应地保护了经济;意大利帮助我们说明了预防资本的重要性。

Artificial Intelligence and Collusion: A Literature Overview 人工智能与共谋:文献综述
Pub Date : 2017-07-21 DOI: 10.2139/ssrn.3656822
Steven Van Uytsel
The use of algorithms in pricing strategies has received special attention among competition law scholars. There is an increasing number of scholars who argue that the pricing algorithms, facilitated by increased access to Big Data, could move in the direction of collusive price setting. Though this claim is being made, there are various responses. On the one hand, scholars point out that current artificial intelligence is not yet well-developed to trigger that result. On the other hand, scholars argue that algorithms may have other pricing results rather than collusion. Despite the uncertainty that collusive price could be the result of the use of pricing algorithms, a plethora of scholars are developing views on how to deal with collusive price setting caused by algorithms. The most obvious choice is to work with the legal instruments currently available. Beyond this choice, scholars also suggest constructing a new rule of reason. This rule would allow us to judge whether an algorithm could be used or not. Other scholars focus on developing a test environment. Still other scholars seek solutions outside competition law and elaborate on how privacy regulation or transparency reducing regulation could counteract a collusive outcome. Besides looking at law, there are also scholars arguing that technology will allow us to respond to the excesses of pricing algorithms. It is the purpose of this chapter to give a detailed overview of this debate on algorithms, price setting and competition law.
在定价策略中使用算法受到竞争法学者的特别关注。越来越多的学者认为,随着对大数据访问的增加,定价算法可能会朝着合谋定价的方向发展。虽然有人提出了这种说法,但有各种各样的回应。一方面,学者们指出,目前的人工智能还没有发展到触发这种结果的程度。另一方面,学者认为算法可能有其他定价结果,而不是合谋。尽管使用定价算法可能导致串通价格的不确定性,但大量学者正在就如何处理算法导致的串通价格制定提出意见。最明显的选择是利用现有的法律文书。除了这种选择,学者们还建议构建一种新的理性规则。这个规则将允许我们判断一个算法是否可以使用。其他学者则专注于开发测试环境。还有一些学者寻求竞争法之外的解决方案,并详细阐述了隐私监管或降低透明度的监管如何抵消共谋的结果。除了关注法律,也有学者认为,技术将使我们能够对定价算法的过度行为做出反应。本章的目的是详细概述关于算法、价格设定和竞争法的辩论。

There is an increasing number of scholars who argue that the pricing algorithms, facilitated by increased access to Big Data, could move in the direction of collusive price setting. Though this claim is being made, there are various responses. On the one hand, scholars point out that current artificial intelligence is not yet well-developed to trigger that result. On the other hand, scholars argue that algorithms may have other pricing results rather than collusion. Despite the uncertainty that collusive price could be the result of the use of pricing algorithms, a plethora of scholars are developing views on how to deal with collusive price setting caused by algorithms. The most obvious choice is to work with the legal instruments currently available. Beyond this choice, scholars also suggest constructing a new rule of reason. This rule would allow us to judge whether an algorithm could be used or not. Other scholars focus on developing a test environment. Still other scholars seek solutions outside competition law and elaborate on how privacy regulation or transparency reducing regulation could counteract a collusive outcome.

Right to Information About, and Involvement in, Environmental Decision Making Along the Silk Road Economic Belt 丝绸之路经济带环境决策的知情权和参与权

The ecological vulnerability of the regions within the Silk Road Economic Belt requires environmental protection. The infrastructure-pillared structure of the Belt and legal procedures on environmental impact assessment (EIA) of various infrastructures inform the article’s approach to environment protection along the Belt through the right to information about and involvement in environmental decision-making (the right to information and involvement). How to protect this right along the Belt? The rights-approach to environment, as the paper first examines, lead to an exploration of the social and historical background of the adoption of the Convention on Access TO Information, Public Participation in Decision-making and Access to Justice in Environmental Matters (Aarhus Convention). Parties to the Aarhus Convention largely overlap with the countries within the Belt. Critical analysis of the EIA legislation and it in practice, and the contradiction within the principle of “public participation” reveal the inadequacy of formal legislation in protecting the right to information and involvement. A case study on informal participation in environmental decision-making in China illustrates the value of informal participation in protecting this right. Informal participation is forming a communicative form of environment governance in Singapore, in which the right to information and involvement is protected. This article argues that informal participation can facilitate the protection of the right to information and involvement along the Belt.
丝绸之路经济带区域的生态脆弱性需要环境保护。“一带一路”以基础设施为支柱的结构和各种基础设施环境影响评价的法律程序,为本文提供了通过环境决策的知情权和参与权(知情权和参与权)来保护“一带一路”环境的途径。如何保护这一权利?本文首先考察了环境权利观,探讨了通过《关于获取信息、公众参与决策和在环境问题上诉诸司法的公约》(《奥胡斯公约》)的社会和历史背景。《奥胡斯公约》的缔约国在很大程度上与“一带”内的国家重叠。对环境影响评价立法及其实践的批判性分析,以及“公众参与”原则内部的矛盾,揭示了正式立法在保护知情权和参与权方面的不足。中国非正式参与环境决策的案例研究说明了非正式参与在保护这一权利方面的价值。非正式参与正在形成新加坡环境治理的一种交流形式,在这种形式中,知情权和参与权受到保护。本文认为,非正式参与可以促进“一带一路”沿线的知情权和参与权保护。
