TThis paper describes a study of the two-sided matching problem with type-specific maximal and minimal quotas with the deferred acceptance mechanism in a student– supervisor assignment. In this problem, both students and supervisors were classified by type according to their affiliations, and the supervisors set type-specific maximal and minimal quotas. In the proposed mechanism, the maximal quotas were dynamically adjusted to fulfill the minimal quotas. We found that while the mechanism may not be strategy-proof, it eliminates justified envy among students of the same “type,” and it achieved feasibility with a certain distributional constraint. Moreover, if the sum of the ranks of students and supervisors in the final assignment is viewed as a measure of welfare, there is no domination relationship between our mechanism and the deferred acceptance mechanism. As evidence, the paper presents a case study of the proposed mechanism in use at a Japanese university.
本文研究了具有延迟接受机制的学生-导师分配中具有特定类型的最大和最小配额的双边匹配问题。在这个问题中,学生和导师都按照所属的类型进行分类,导师设置针对类型的最大和最小配额。在该机制中,最大配额被动态调整以满足最小配额。我们发现,虽然这种机制可能不是策略证明,但它消除了同一“类型”学生之间的合理嫉妒,并且在一定的分配约束下实现了可行性。此外,如果学生和导师在最终作业中的排名总和被视为福利的衡量标准,那么我们的机制和延迟接受机制之间就不存在支配关系。作为证据,本文提出了一个在日本一所大学使用该机制的案例研究。

Civil Liberties and Social Structure 公民自由和社会结构
Pub Date : 2020-06-27 DOI: 10.2139/ssrn.3637178
Selman Erol, Camilo García-Jimeno
Governments rely on a variety of forms of coercion to aggregate distributed information relevant to governmental objectives from the prosecution of regime stability threats to terrorism or epidemics. To do so, they exploit the existing social structure, as reliable information will often come from friends and acquaintances. Civil liberties, in turn, restrict the government’s ability to exercise such coercion. We present an equilibrium theory of the joint determination of social structure and civil liberties. The depth of civil liberties shapes citizens’ decisions on how intensely and with whom to socialize. Features of the social structure such as its cohesiveness and the extent of segregation, in turn, shape the government’s willingness to enforce civil liberties protections such as search and seizure restrictions, standards of proof, and equal treatment under the law. We show that the relationship between civil liberties and social structure is mediated by a commitment problem by the government, and that this commitment problem is in turn mediated by the strength of civil society. We also show that segregation and unequal treatment sustain each other, characterize when unequal treatment against a minority or a majority can be sustained, and how equilibrium social cohesiveness and civil liberties respond to the arrival of widespread surveillance technologies, shocks to collective perceptions about the likelihood of threats or the importance of privacy, or to community norms such as codes of silence.
各国政府依靠各种形式的强制手段收集与政府目标有关的已发布信息,从起诉政权稳定威胁到恐怖主义或流行病。为了做到这一点,他们利用了现有的社会结构,因为可靠的信息通常来自朋友和熟人。反过来,公民自由限制了政府行使这种强制的能力。我们提出了社会结构和公民自由共同决定的均衡理论。公民自由的深度决定了公民对社交的强烈程度和与谁交往的决定。社会结构的特点,如凝聚力和隔离程度,反过来又决定了政府执行公民自由保护的意愿,如搜查和扣押限制、举证标准和依法平等对待。我们表明,公民自由和社会结构之间的关系是由政府的承诺问题调解的,而这个承诺问题反过来又由公民社会的力量调解。我们还表明,隔离和不平等待遇是相互维持的,体现了对少数人或多数人的不平等待遇何时可以持续,以及平衡的社会凝聚力和公民自由如何应对广泛监控技术的到来,对威胁可能性或隐私重要性的集体观念的冲击,或对沉默准则等社区规范的冲击。

A Problem Shared Is a Problem Halved? Risky Tax Avoidance Decisions and Intra-Group Payoff Conflict 问题共享,问题减半?风险避税决策与群体内收益冲突
Pub Date : 2020-06-15 DOI: 10.2139/ssrn.3626982

This paper investigates the dynamics of group decisions regarding risky tax avoidance strategies using a laboratory experiment. To identify the causes of risk taking by groups, we compare individual to group decisions in three scenarios. The first scenario allocates payoffs from group decisions equally to all members of a group. The second and third scenario introduce intra-group payoff conflict as a new influential factor in group dynamics. Hereby, we separate intra-group payoff conflicts in the distribution of costs and profits. This manipulation allows us to disentangle group discussion effects resulting from the competing theories of polarization and diversification of opinions. Our overall findings support a predominant diversification of opinions effect. When group members share all payoffs equally, this effect overcomes polarization in 100% of the cases where outstanding individuals are risk averse, while group polarization appears to be more likely towards outstanding risk loving subjects. Intra-group payoff conflict shifts these likelihoods, supporting the importance of rational arguments in group polarization. Consequently, our experimental results support a strong increase in the level of average tax avoidance following group decisions in case of all or negative outcomes being shared equally by group members. Intra-group payoff in the distribution of costs, however, removes this difference and shifts, both individual and group preferences, towards safety.
本文利用实验室实验研究了关于高风险避税策略的群体决策动力学。为了确定群体承担风险的原因,我们在三种情况下比较了个人和群体决策。第一个场景将群体决策的收益平等地分配给群体的所有成员。第二和第三种情景将群体内收益冲突作为群体动力学的一个新的影响因素引入。因此,我们将成本和利润分配中的集团内部收益冲突分开。这种操纵使我们能够理清由于两极分化和意见多样化理论的竞争而产生的小组讨论效应。我们的总体研究结果支持意见多样化的主要效应。当团队成员平均分享所有收益时,这种效应在100%的情况下克服了两极分化,在这种情况下,杰出的个人是风险厌恶者,而群体两极分化似乎更可能发生在杰出的风险偏好者身上。群体内的收益冲突改变了这些可能性,支持了理性争论在群体极化中的重要性。因此,我们的实验结果支持在所有或负面结果由群体成员平均分享的情况下,群体决策后平均避税水平的大幅提高。然而,成本分配中的群体内收益消除了这种差异,并将个人和群体的偏好转向安全。

More than Average Income? Preferences for Income Equality and Mobility Statistics 超过平均收入?收入平等偏好与流动性统计
Pub Date : 2020-06-15 DOI: 10.2139/ssrn.3627896
Bernardo Lara, Kenneth Shores
To describe preferences for income mobility/equality, we generate statistics that can be interpreted as marginal rates of substitution and converted to willingness-to- pay (WTP). All else constant, U.S. residents are willing to pay $2,736 dollars to increase income equality 10 percentiles and $1,778 dollars to increase income mobility 10 percentiles. Liberals’ WTP for income equality is two times larger than conservatives’; there are no significant differences in the WTP for mobility. Educational attainment, income, ideology, and beliefs about upward mobility negatively predict a WTP for income equality; the only predictor of the WTP for mobility is gender.
为了描述对收入流动性/平等的偏好,我们生成了可以解释为边际替代率并转换为支付意愿(WTP)的统计数据。在其他条件不变的情况下,美国居民愿意支付2736美元来提高收入平等性10个百分点,愿意支付1778美元来提高收入流动性10个百分点。自由派在收入平等上的WTP是保守派的两倍;移动性的WTP没有显著差异。受教育程度、收入、意识形态和向上流动的信念负向预测收入平等的WTP;流动性WTP的唯一预测指标是性别。

Social Preferences Under the Shadow of the Future 未来阴影下的社会偏好
Pub Date : 2020-06-08 DOI: 10.2139/ssrn.3622125

Social interactions predominantly take place under the shadow of the future. Previous literature on infinitely repeated games has highlighted the primary role of self-interested strategic considerations in explaining outcomes. Using indefinitely repeated prisoner’s dilemma games, this paper demonstrates experimentally the importance of social preferences for achieving efficient cooperative outcomes. Sorting agents by their pro-sociality, we find that cooperation is three to four times higher among prosocial players compared to selfish players. We also show that social preferences are less important when individuals interact in mixed populations. This can explain why the influence of social preferences has not been detected in previous studies.
社会互动主要发生在未来的阴影下。之前关于无限重复博弈的文献强调了自利战略考虑在解释结果中的主要作用。利用无限重复的囚徒困境博弈,实验证明了社会偏好对实现高效合作结果的重要性。我们发现亲社会参与者的合作程度是自私参与者的三到四倍。我们还表明,当个体在混合群体中互动时,社会偏好不那么重要。这可以解释为什么社会偏好的影响在以前的研究中没有被发现。

Dissecting Inequality-Averse Preferences 剖析不平等厌恶偏好
Pub Date : 2020-06-01 DOI: 10.2139/ssrn.3729710

Although different approaches and methods have been used to measure inequality aversion, there remains no consensus about its drivers at the individual level. We conducted an experiment on a sample of more than 1,576 first-year undergraduate economics and business students in Uruguay to understand why people are inequality averse. We elicited inequality aversion by asking participants to make a sequence of choices between hypothetical societies characterized by varying levels of average income and income inequality. In addition, we use randomized information treatments to prime participants into competing narratives regarding the sources of inequality in society. The main findings are that (1) the prevalence of inequality aversion is high: most participants’ choices revealed inequality-averse preferences; (2) the extent of inequality aversion depends on the individual’s position in the income distribution; (3) individuals are more likely to accept inequality when it comes from effort rather than luck regardless of their income position; (4) the effect of social mobility on inequality aversion is conditional on individual’s income position: preferences for mobility reduces inequality aversion for individuals located at the bottom of the income distribution, where risk aversion cannot play any role.
尽管不同的方法和方法被用来衡量不平等厌恶,但在个人层面上,对其驱动因素仍未达成共识。我们对乌拉圭1576多名经济学和商学一年级本科生进行了一项实验,以了解人们为什么厌恶不平等。我们通过要求参与者在不同平均收入水平和收入不平等的假设社会之间做出一系列选择,引发了对不平等的厌恶。此外,我们使用随机信息处理,使参与者进入关于社会不平等来源的竞争叙述。研究发现:(1)不平等厌恶的普遍程度较高,大多数参与者的选择显示出不平等厌恶偏好;(2)厌恶不平等的程度取决于个人在收入分配中的位置;(3)无论收入状况如何,个体都更容易接受来自努力而非运气的不平等;(4)社会流动性对不平等厌恶的影响取决于个体的收入地位:对于处于收入分配底部的个体,流动性偏好降低了不平等厌恶,风险厌恶无法发挥任何作用。

Russian Abstract: Цель статьи – структурировать основные проблемы, с которыми сталкивается современная теория рентоориентированного поведения. Предмет исследования – на основе обзора различных подходов к содержанию категории «рента» в зарубежной научной литературе рассмотреть генезис концепта рентоискательства. В результате обоснована правомерность разграничения понятий «рентоориентированное поведение» и «рентоискательство». Проведенный анализ современной российской научной литературы выявил наличие взаимоисключающих подходов российских исследователей к содержанию категории ренты.

Рассмотрены попытки интеграции концептов ренты и рентоискательства в рамках единой теории. В заключении авторы предлагают собственное определение категории ренты, исходя из местоположения субъекта присвоения в социально-экономическом пространстве. Представленное определение направлено на конструктивное решение проблемы «несводимости» доминирующих концептов ренты и рентоориентированного поведения.

English Abstract: The purpose of the article is to structure the main problems faced by the modern theory of rent-oriented behavior. Subject of the research is based on a review of various approaches to the content of the "rent" category in foreign scientific literature, to consider the genesis of the concept of rent-seeking. As a result, the legitimacy of the distinction between the concepts of "rent-oriented behavior" and "rent-seeking" is substantiated. The analysis of modern Russian scientific literature revealed the presence of mutually exclusive approaches of Russian researchers to the content of the annuity category. The multidirectionality of studies of Russian and foreign authors on rental issues, which is the reason for the “irreducibility” of the dominant theory of rent-seeking and the theory of rental relations in Russia, is shown. Attempts to integrate the concepts of rent and rent-seeking in the framework of a unified theory are considered. In conclusion, the authors propose their own definition of the category of rent based on the location of the subject of appropriation in the socio-economic space. The presented definition is aimed at a constructive solution to the problem of “irreducibility” of the dominant concepts of rent and rent-oriented behavior. A side result was the formulation of the problem of establishing the coordinate systems of the political and institutional and economic space.
俄罗斯的Abstract:本文的目的是构造现代行为理论面临的主要问题。研究的主题是,根据外国科学文献中对“租金”类别的不同研究方法来研究“租金”概念的起源。因此,区分“以市场为导向的行为”和“以市场为导向的行为”是合理的。对俄罗斯现代科学文献的分析显示,俄罗斯研究人员对租金类别的相互排斥态度。俄罗斯和外国关于租金问题的作者的研究显示了多样化,这导致了占主导地位的任意性理论和俄罗斯的任意性理论。在统一理论的框架内,人们试图整合租金概念和成本扭曲。最后,作者根据受试者在社会经济空间中的位置提出了自己的租赁类别。该定义旨在建设性地解决占主导地位的租金概念和基于成本的行为的不确定性问题。一个副作用是建立政治经济和制度经济空间的坐标系问题。英语Abstract:这首诗是由rent- orivior的现代理论引起的主要问题。在《科学文献》中,《宗教文献》中的“宗教文献”是对“宗教文献”的基本评论。作为一种反应,“分离主义”的传统被称为“分离主义”,而“分离主义”的概念被接受了。现代俄罗斯科学literature评论了俄罗斯对《卡特戈里》的评论。俄罗斯工作室多方面的权威和权威在rental issues,为什么这是对“rent- seoplity”和“rental - relations”的回归,这是一个挑战。在统一理论框架的框架中,Attempts被引入。在conclusion中,authors决定了在社会经济空间中为次等空间提供的基础。最具代表性的定义是对“irredubility”问题的定义。这是政治、制度和经济空间问题的形式问题。

Wildfire Crime and Social Vulnerability in Italy: A Panel Investigation 意大利野火犯罪和社会脆弱性:一个小组调查
Pub Date : 2020-05-10 DOI: 10.2139/ssrn.3597341
A. Canepa, Federico Drogo
In this paper, we analyse the socio–economic determinants of wildfire crime in Italy through panel data at the regional level. Using fixed-effect Poisson models and fixed-effect quantile panel regression analysis, it is found that social vulnerability factors such as poverty, organised crime and inequality in income play an important role in driving wildfire crime. The quantile regression analysis highlights a significant heterogeneity of the effects of driving factors across the Italian peninsula. Finally, we also extend our analysis to investigate the effect of economic downturns on wildfire crime and we find a positive correlation between a deterioration of per capita income and wildfire crime.
在本文中,我们通过区域层面的面板数据分析了意大利野火犯罪的社会经济决定因素。利用固定效应泊松模型和固定效应分位数面板回归分析发现,贫困、有组织犯罪和收入不平等等社会脆弱性因素在野火犯罪的驱动中起着重要作用。分位数回归分析突出了意大利半岛各地驱动因素影响的显著异质性。最后,我们还扩展了我们的分析,以调查经济衰退对野火犯罪的影响,我们发现人均收入的下降与野火犯罪之间存在正相关。

Social Groups with Selfish Individuals 有自私个体的社会群体

I test the effect of multiple pivotal players on unfair choices in a setup with a leader and two followers deciding on whether to expropriate the payoff of a group member. Comparing unanimity decisions to individual decisions within the group, I find that leaders are fairer in the unanimity rule compared to individual decision-making. Followers are more unfair than leaders. These findings refute multiple pivotality as a source of unfair group decisions, and are in line with image and harm responsibility concerns. Control treatments suggest that a minority might prefer not to collectively redistribute the wealth away from a victim.
我测试了多个关键参与者对不公平选择的影响,在一个设置中,一个领导者和两个追随者决定是否剥夺一个团队成员的收益。将全体一致决策与群体内的个人决策进行比较,我发现领导者在全体一致规则下比个人决策更公平。跟随者比领导者更不公平。这些发现驳斥了多重枢纽作为不公平群体决策的来源,并符合形象和伤害责任的担忧。对照治疗表明,少数人可能不愿意集体重新分配受害者的财富。

Three Myths About Federal Regulation 关于联邦监管的三个误解
P. McLaughlin, C. Mulligan
Despite evidence to the contrary, three common myths persist about federal regulations. The first myth is that many regulations concern the environment, but in fact only a small minority of regulations are environmental. The second myth is that most regulations contain quantitative estimates of costs or benefits. However, these quantitative estimates appear rarely in published rules, contradicting the impression given by executive orders and Office of Management and Budget guidance, which require cost-benefit analysis (CBA) and clearly articulate sound economic principles for conducting CBA. Environmental rules have relatively higher-quality CBAs, at least by the low standards of other federal rules. The third myth, which is particularly relevant to the historic regulations promulgated during the COVID-19 pandemic, is the misperception that regulatory costs are primarily clerical, rather than opportunity or resource costs. If technocrats have triumphed in the regulatory arena, their victory has not been earned by the merits of their analysis.
尽管有相反的证据,但关于联邦法规的三个常见误解仍然存在。第一个误解是,许多法规都与环境有关,但实际上只有一小部分法规是与环境有关的。第二个误解是,大多数法规都包含对成本或收益的定量估计。然而,这些定量估计很少出现在公布的规则中,这与行政命令和管理和预算办公室的指导意见相矛盾,行政命令和管理和预算办公室的指导意见要求进行成本效益分析(CBA),并清楚地阐明进行CBA的合理经济原则。环境法规的cba质量相对较高,至少与其他联邦法规的低标准相比是这样。第三个误解与COVID-19大流行期间颁布的历史性法规特别相关,即错误地认为监管成本主要是文书成本,而不是机会或资源成本。如果技术官僚在监管领域取得了胜利,那么他们的胜利并不是由于他们的分析的优点。
