We study the role of social learning in the diffusion of cash crops in a resettled village economy in northeastern Brazil. We combine detailed geo-coded data on farming plots with dyadic data on social ties among settlers, and we leverage natural exogenous variation in network formation induced by the land occupation movement and the agrarian reform. By using longitudinal data on farming decisions over 15 years we find consistent evidence of significant peer effects in the decision to farm new cash fruits (pineapple and passion fruit). Our results suggest that social diffusion is heterogeneous along observed plot and crop characteristics, i.e. farmers growing water-sensitive crop are more likely to respond to the actions of peers with similar water access conditions.
我们研究了社会学习在巴西东北部一个重新安置的村庄经济中经济作物扩散的作用。我们将农业用地的详细地理编码数据与定居者之间社会关系的二元数据结合起来,并利用由土地占领运动和土地改革引起的网络形成中的自然外生变化。通过使用超过15年的农业决策纵向数据,我们发现在种植新的现金水果(菠萝和百香果)的决策中存在显著的同伴效应的一致证据。我们的研究结果表明,根据观察到的地块和作物特征,社会扩散是异质的,即种植水敏感作物的农民更有可能对具有相似水获取条件的同伴的行为做出反应。

Viewing the Environmental Justice Critiques of Greenhouse Gas Auction-Cap-Trade-and-Invest Programs Through an Ethical Lens 从伦理角度看温室气体拍卖-限额交易-投资项目的环境正义批评
Pub Date : 2021-01-24 DOI: 10.2139/ssrn.3772045
R. McKinstry
Existing North American regional programs for capping and reducing greenhouse gas emissions have come under criticism based on concerns regarding their perceived impact on environmental justice communities. When viewed through an ethical lens, programs that distribute emissions allowances by way of an auction with a sufficient reserve price comport better with principles of distributive justice than traditional permitting mechanisms, which award pollution allowances based on prior appropriation and do so without compensating society for consumption of a scarce resource. There is no evidence supporting claims that these programs increase levels having adverse health effects in disadvantaged communities. While levels of pollutants having adverse impacts on EJ communities were disproportionately increasing before the 2013 initiation of the California program, that trend reversed after the program’s initiation. By reinvesting auction revenues in programs to increase energy conservation, efficiency, and distributed generation in disadvantaged communities, the existing programs offset or eliminate adverse price impacts.
现有的北美地区限制和减少温室气体排放的计划受到了批评,因为人们担心这些计划会对环境正义团体产生影响。从道德的角度来看,通过有足够底价的拍卖方式分配排放配额的计划比传统的许可机制更符合分配正义的原则,传统的许可机制是根据事先的拨款发放污染配额,而不是补偿社会对稀缺资源的消耗。没有证据支持这样的说法,即这些项目增加了对弱势社区健康产生不利影响的水平。虽然在2013年加州项目启动之前,对EJ社区产生不利影响的污染物水平不成比例地增加,但该项目启动后,这一趋势发生了逆转。通过将拍卖收入再投资于提高弱势社区节能、能效和分布式发电的项目,现有项目抵消或消除了不利的价格影响。

Price Limits in a Tradable Performance Standard 可交易性能标准中的价格限制
Pub Date : 2021-01-01 DOI: 10.3386/W28368
Banban Wang, W. Pizer, Clayton Munnings
Tradable performance standards are widely used sectoral regulatory policies. Examples include the US lead phasedown, fuel economy standards for automobiles, renewable portfolio standards, low carbon fuel standards, and—most recently—China’s new national carbon market. At the same time, theory and experience with traditional cap-and-trade programs suggests an important role for price limits in the form of floors, ceilings, and reserves. In this paper we develop a simple analytical model to derive the welfare comparison between tradable performance standards and a price-based alternative. This works out to be is a simple variant of the traditional Weitzman prices-versus-quantities result. We use this result to show that substantial gains could arise from shifting two programs, China’s new national carbon market (~60% gain) and the California Low Carbon Fuel Standard (~20% gain), to a price mechanism. This will generally be true when the coefficient of variation in the price under a TPS is larger than 50%. We end with a discussion of implementation issues, including full and partial consignment auctions based on actual and expected output.
可交易绩效标准是广泛使用的行业监管政策。例子包括美国逐步减少铅、汽车燃油经济性标准、可再生能源组合标准、低碳燃料标准,以及最近中国新的全国碳市场。与此同时,传统总量管制与交易计划的理论和经验表明,价格限制以最低限额、最高限额和储备的形式发挥着重要作用。在本文中,我们开发了一个简单的分析模型来推导可交易绩效标准和基于价格的替代方案之间的福利比较。这被证明是传统韦茨曼价格对数量结果的一个简单变体。我们利用这一结果表明,将中国新的全国碳市场(收益约60%)和加州低碳燃料标准(收益约20%)这两个项目转变为价格机制可能会产生可观的收益。当TPS下的价格变动系数大于50%时,这通常是正确的。最后,我们讨论了实施问题,包括基于实际和预期产出的全部和部分寄售拍卖。

A Review of Nudges: Definitions, Justifications, Effectiveness 《轻推:定义、理由、有效性》综述
Pub Date : 2020-11-10 DOI: 10.2139/ssrn.3728512
Luca Congiu, Ivan Moscati
In an influential book published in 2008, Thaler and Sunstein suggested a novel approach to policy making based on the notion of a ‘nudge.’ Roughly speaking, a nudge is defined as an aspect of the decisional context that steers people’s decisions by acting on their cognitive biases. The book generated an intense debate, over the course of which concerns were raised about: (1) the exact definition of nudges, (2) their ethical justifiability, and (3) their effectiveness. In this paper, we review the nudge literature by focusing on these three concerns.
在2008年出版的一本颇具影响力的书中,塞勒和桑斯坦提出了一种基于“助推”概念的新政策制定方法。粗略地说,助推被定义为决策环境的一个方面,它通过人们的认知偏见来引导人们的决策。这本书引发了一场激烈的辩论,在此过程中,人们提出了以下问题:(1)轻推的确切定义,(2)其道德合理性,(3)其有效性。在本文中,我们通过关注这三个问题来回顾轻推文献。

Principles to Advance Energy Justice for Native Americans 促进美洲原住民能源公平的原则
Pub Date : 2020-10-01 DOI: 10.2139/ssrn.3770406
C. Sandoval
On many Native American reservations, lack of energy access reduces economic, health, and educational opportunities. The U.S. Energy Information Administration (EIA) reported in 2000 that 14% of households on Native American reservations had no access to electricity, compared to 1.4% nationally. Neither the EIA, nor the U.S. Census Bureau have published reliable updates on the status of the Native American Reservation electricity gap. While several projects led by Native American tribes have narrowed the Native American reservation electricity gap, thousands of households and institutions serving tribal members in the United States remain without electric grid access in 2020. The electric grid’s absence fuels lack of access to infrastructure interconnected with electricity including water, water treatment, telephone, and Internet facilities and services. Enabling electricity access will improve fire safety, water and wastewater access and treatment, telecommunications access, health, educational, economic, and civic opportunity.

This article proposes six principles to advance energy justice for Native Americans:

Principle 1: Respect Tribal Sovereignty;

Principle 2: Energy Access is Foundational to Energy
Justice; Principle

3: Foster Tribal Energy Ownership and Clean Energy Opportunities; Principle

4: Support Native American Energy Contracting, Employment, and Entrepreneurial Opportunities; Principle

5: Promote Access to Energy Efficiency and Energy Affordability Programs; Principle

6: Assess and Address the Impact of Climate Change on Native American Reservations, Tribal Lands, and Native American Tribal Members. This article concludes that fostering energy justice for Native Americans will improve prospects for all Americans, advance our economy, protect the environment, and promote equity.
在许多印第安人保留地,缺乏能源获取减少了经济、健康和教育机会。美国能源情报署(EIA)在2000年的报告中称,14%的印第安人保留地家庭没有电力供应,而全国的这一比例为1.4%。美国环境影响评估署和美国人口普查局都没有公布有关美国原住民保留区电力缺口状况的可靠更新。虽然印第安部落领导的几个项目缩小了印第安人保留地的电力差距,但到2020年,美国仍有数千户家庭和为部落成员服务的机构没有电网接入。电网的缺失导致人们无法获得与电力相连的基础设施,包括水、水处理、电话、互联网设施和服务。实现电力供应将改善消防安全、水和废水的获取和处理、电信接入、卫生、教育、经济和公民机会。本文提出了促进美洲原住民能源正义的六项原则:原则1:尊重部落主权;原则2:能源获取是能源公正的基础;原则3:促进部落能源所有权和清洁能源机会;原则4:支持美洲原住民能源合同、就业和创业机会;原则5:促进获得能源效率和能源可负担性方案;原则6:评估和解决气候变化对印第安人保留地、部落土地和印第安人部落成员的影响。本文的结论是,促进美洲原住民的能源公平将改善所有美国人的前景,促进我们的经济发展,保护环境,促进公平。

Polarization, Hyperbole and the Battle for Control over the Narrative 两极分化、夸张和对叙事控制权的争夺
Pub Date : 2020-07-13 DOI: 10.2139/ssrn.3683160
G. Rausser, Leo Simon, Jinhuan Zhao
We investigate the causal connections between elite polarization, hyperbole in public discourse and narrative control. The victor of a narrative battle gains a strategic advantage in hyperbole, steering a contentious policy in its preferred direction. This gain, weighed against the information loss from hyperbole, determines the equilibrium narrative. Platform polarizations, which relate to elites’ messages, are induced by, and amplify, preference polarizations, which relate to their political orientations. IS polarizations, in which two opposing factions move further apart, intensify the narrative battle and decrease social welfare. These effects are reversed for IB polarizations, in which each faction becomes more homogeneous.
我们研究了精英极化、公共话语中的夸张和叙事控制之间的因果关系。叙事之战的胜利者在夸张中获得战略优势,将一项有争议的政策引向自己喜欢的方向。这种增益与夸张所造成的信息损失相权衡,决定了均衡叙事。与精英传递的信息相关的平台极化是由与其政治取向相关的偏好极化诱导并放大的。伊斯兰国的两极分化,即两个对立的派别进一步分化,加剧了叙事之争,减少了社会福利。这些影响在IB极化中是相反的,在IB极化中,每个阵营变得更加均匀。

Pervasive Infancy: Reassessing the Contract Capacity of Adults in Modern America 无处不在的婴儿期:重新评估现代美国成年人的契约能力
Pub Date : 2020-06-18 DOI: 10.2139/ssrn.3526991

This article argues that the law of consumer contracts should permit adults to access the same protections available to children where data about adult performance indicates that the two categories of people are similarly situated in the domain of consumer contracts. In making this claim, this article relies upon a description of capacity articulated by Professor Martha Nussbaum in her important work on the subject. Professor Nussbaum explains that capacity is a function, not only of a person’s innate capabilities, but of a person’s opportunity or ability to deploy those capabilities within environmental limitations. Capacity to contract in a free society has demanded sufficient internal self-control to direct action and make decisions we would expect of a free person vested with a set of important personal rights. Nussbaum’s standard raises the possibility that even people with substantial internal capabilities may not have capacity if the environment in which they are seeking to express their capacities negates them. This article argues that the law of consumer contracts is one such domain. It therefore argues that this domain should reassign risks between consumers and sellers in the consumer contracting market, where data about adult decision-making in the domain suggests that adults do not have the power to protect their contract rights through bargaining by applying reasoned decision-making. It does so as a means of saving the very institution of contract law itself, which is a central mechanism for securing freedom of choice for Americans.
本文认为,消费者合同法应允许成年人获得与儿童相同的保护,如果有关成人表现的数据表明,这两类人在消费者合同领域的地位相似。在提出这一主张时,本文依赖于玛莎·努斯鲍姆教授在她关于这一主题的重要工作中对能力的描述。努斯鲍姆教授解释说,能力是一种功能,不仅是一个人的先天能力,而且是一个人在环境限制下部署这些能力的机会或能力。自由社会中的契约能力要求有足够的内部自我控制能力来指导行动和做出决定,这是我们所期望的一个被赋予一系列重要个人权利的自由人的行为。努斯鲍姆的标准提出了一种可能性,即即使是具有强大内在能力的人,如果他们寻求表达能力的环境否定了他们的能力,他们也可能没有能力。本文认为,消费者合同法就是这样一个领域。因此,本文认为该领域应该在消费者合同市场中重新分配消费者和销售者之间的风险,该领域中有关成年人决策的数据表明,成年人没有权力通过合理决策来保护他们的合同权利。它这样做是为了拯救合同法本身的制度,而合同法本身是保障美国人选择自由的核心机制。

A Model of Stock-Market-Based Rulemaking 基于股市的规则制定模型
Pub Date : 2020-05-29 DOI: 10.2139/ssrn.3440321
Yoon-Ho Alex Lee
We consider the extent to which a government regulator can harness information about a proposed rule from observing the stock price movements of the affected firms—information the regulator may in turn use to deliberate whether to adopt the rule. The rule comes with an uninformed ex ante (expected) value, which can be positive or negative. We find that if the rule’s ex ante value is positive and the regulator fully relies on the aggregate market reaction to guide its decision, then with many firms in the market, prices will exhibit maximal informativeness. When the ex ante value is negative, however, the regulator’s reliance on the market will dampen speculators’ incentives to gather information, and prices will become completely uninformative. This latter effect, however, can be mitigated if the regulator’s reliance is only partial. We also consider the presence of stakeholders who may be motivated to manipulate the market to steer the regulator toward privately beneficial outcomes. We find that with many firms in the market, such stakeholders’ incentives to manipulate will dissipate. The theoretical findings of this article suggest the potential benefits of a stock-market-based rulemaking mechanism in the absence of other forms of reliable empirical evidence.
我们考虑政府监管机构在多大程度上可以通过观察受影响公司的股价变动来利用有关拟议规则的信息——监管机构可能反过来使用这些信息来考虑是否采用该规则。该规则带有一个未知的事前(预期)值,可以是正的,也可以是负的。我们发现,如果规则的先验值为正,且监管者完全依赖市场的总体反应来指导其决策,那么当市场上有许多公司时,价格将表现出最大的信息性。然而,当事前价值为负时,监管机构对市场的依赖将抑制投机者收集信息的动机,价格将变得完全没有信息。然而,如果监管者只是部分依赖,后一种影响是可以减轻的。我们还考虑了利益相关者的存在,他们可能有动机操纵市场,引导监管机构走向对私人有利的结果。我们发现,当市场上有许多公司时,这些利益相关者的操纵动机将消散。本文的理论发现表明,在缺乏其他形式的可靠经验证据的情况下,以股票为基础的规则制定机制的潜在好处。

Some Commentaries From the Neurosciences Point of View About the Relations Between Citizens and Public Agencies 从神经科学的角度看公民与公共机构的关系
Pub Date : 2020-04-16 DOI: 10.2139/ssrn.3577598
A. D. da Rocha
The success story continues making Nudge well read and much applied. The key message is that people are irrational on their decision making and need to be guided by policy markers, which are able to have useful insights from Psychology and Behavioral Economics about how to elaborate choice structures to rationalize people’s financial behavior. Inertia is one popular of these insights and refers to the tendency of humans to procrastinate in making choices. This tendency is acknowledged but not understood and explained. The same occurs with other reported insights. In contrast, the present paper proposes any decision guaranteeing the individual biological; psychological and social homeostasis are rational despite being or not the expected decision supported by any formal model. Most of the important human decisions are about keeping homeostasis within boundaries promoting well being, hence resulting from complex analyses of benefits; risks and costs from both the personal and social point of view as carried out by two different Personal and Social Decision Networks. Rational choice selects, therefore, high beneficial goods or services for promoting homeostasis at lowest risk and cost from both personal and social point of views. A decision neural model for decision making is presented and used to illustrate how rational choices are computed to guarantee individual homeostasis, and to propose that individuals seem to be irrational because the proposed economic formal theories take into consideration just the policy maker point of view disregarding the individual needs.
成功的故事继续使《助推》被广泛阅读和应用。关键的信息是,人们在决策时是非理性的,需要政策制定者的指导,这些政策制定者能够从心理学和行为经济学中获得有用的见解,说明如何精心设计选择结构,使人们的金融行为合理化。惯性是这些观点中最受欢迎的一种,它指的是人类在做出选择时拖延的倾向。这种倾向已得到承认,但尚未得到理解和解释。其他报告的见解也是如此。相反,本文提出了任何保证个体生物学的决策;心理和社会的内稳态是理性的,尽管它是否是任何正式模型所支持的预期决策。大多数重要的人类决策都是关于在促进福祉的边界内保持体内平衡,因此产生于对利益的复杂分析;风险和成本,从个人和社会的角度来看,由两个不同的个人和社会决策网络进行。因此,从个人和社会的角度来看,理性选择以最低的风险和成本选择高效益的商品或服务来促进体内平衡。本文提出了一个决策神经模型,用于说明如何计算理性选择以保证个人的内稳态,并提出个人似乎是非理性的,因为所提出的经济形式理论只考虑了政策制定者的观点,而忽视了个人的需求。

The key message is that people are irrational on their decision making and need to be guided by policy markers, which are able to have useful insights from Psychology and Behavioral Economics about how to elaborate choice structures to rationalize people’s financial behavior. Inertia is one popular of these insights and refers to the tendency of humans to procrastinate in making choices. This tendency is acknowledged but not understood and explained.

This paper examines firms’ adaptation to long-term changes in climatic conditions. Using detailed information on establishments owned by U.S. public firms, we show that higher abnormal temperatures over the previous five years in a county lead to a significant reduction in local employment and the number of establishments. The decline in employment and establishments is larger for firms in non-tradable and consumer-oriented sectors, suggesting that firms’ adaptation is largely due to a decline in local consumer demand. Additional tests show that prolonged high temperatures lead to lower consumption, higher unemployment rate, lower wage, and more out-migration across regions.
本文考察了企业对气候条件长期变化的适应。利用美国上市公司拥有的企业的详细信息,我们表明,在过去的五年里,一个县的高温异常导致当地就业和企业数量的显著减少。非贸易部门和面向消费者部门的企业的就业和机构的下降幅度更大,这表明企业的适应主要是由于当地消费者需求的下降。进一步的测试表明,持续的高温会导致消费下降、失业率上升、工资下降和跨地区的外迁。
