Abstract ‘Right to Buy’, a large-scale natural experiment whereby incumbent tenants in public housing could buy properties at heavily subsidised prices, increased the United Kingdom homeownership rate by over 10 percentage points between its 1980 introduction and the 1990s. This paper studies the impact of this reform on crime by leveraging exogenous variation in eligibility for the policy. Results show that Right to Buy generated significant property crime reductions. Behavioural changes of incumbent tenants and renovation of public properties were the main drivers of this crime reduction. This is evidence of a novel means by which subsidised homeownership and housing policy can reduce criminality.
“购买权”是一项大规模的自然实验,使公共住房的现有租户可以以大量补贴的价格购买房产,从1980年引入到20世纪90年代,英国的住房自有率提高了10个百分点以上。本文通过利用政策适用资格的外生变异来研究这一改革对犯罪的影响。结果表明,“购买权”大大减少了财产犯罪。现有租户的行为改变和公共物业的翻新是犯罪率下降的主要原因。这证明了补贴住房所有权和住房政策可以减少犯罪的一种新手段。

Abstract We experimentally test how psychological motivations can impact the processing of purely objective information. We first document that, when the high-stakes College Entrance Exam is held in the month of Ramadan, Chinese Muslim students perform significantly worse. When asked about the impact of fasting, they severely underestimate the cost of taking the exam during Ramadan, even when presented with direct empirical evidence. In the experiment, we randomly offer students reading materials in which well-respected Muslim clerics explain that it is permissible to postpone the fast until after the exam. Consistent with an interpretation of motivated cognition, students who receive the material distort the statistics about the fasting cost significantly less and become more accepting of delaying the fast for the exam.
我们通过实验测试心理动机如何影响纯客观信息的处理。我们首先证明,当高风险的大学入学考试在斋月举行时,中国穆斯林学生的表现明显更差。当被问及禁食的影响时,他们严重低估了在斋月期间参加考试的成本,即使有直接的经验证据。在实验中,我们随机给学生提供一些阅读材料,在这些材料中,受人尊敬的穆斯林神职人员解释说,将斋戒推迟到考试之后是允许的。与动机认知的解释一致,收到材料的学生扭曲了关于禁食成本的统计数据,并且更容易接受推迟禁食以参加考试。

Urban Sprawl and Social Capital: Evidence from Indonesian Cities 城市扩张与社会资本:来自印度尼西亚城市的证据

Abstract We use detailed data from Indonesian cities to study how variation in density within urban areas affects social capital. For identification, we instrument density with soil characteristics, and control for community averages of observed characteristics. Under plausible assumptions, these controls address sorting on observables and unobservables. We find that lower density increases trust in neighbours and community participation. We also find that lower density is associated with reduced interethnic tolerance, but this relationship is explained by sorting. Heterogeneity analysis suggests that crime in dense areas undermines community trust and participation, intensifying the negative impact of density.
摘要本文利用印度尼西亚城市的详细数据,研究城市区域内人口密度的变化对社会资本的影响。为了识别,我们用土壤特征来测量密度,并控制观测特征的群落平均值。在合理的假设下,这些控制处理可观察和不可观察的分类。我们发现,低密度增加了对邻居的信任和社区参与。我们还发现,较低的密度与较低的种族间容忍度有关,但这种关系可以用分类来解释。异质性分析表明,人口密集地区的犯罪破坏了社区的信任和参与,加剧了人口密度的负面影响。

Unraveling Firms: Demand, Productivity and Markups Heterogeneity 拆解企业:需求、生产率和价差异质性

Abstract We develop a novel framework that simultaneously allows recovering heterogeneity in demand, quantity total factor productivity and markups across firms while leaving the correlation between the three dimensions unrestricted. We accomplish this by explicitly introducing demand heterogeneity and systematically exploiting assumptions used in previous productivity estimation approaches. In doing so, we provide an exact decomposition of revenue productivity in terms of the underlying heterogeneities, thus bridging the gap between quantity and revenue productivity estimations. We use Belgian firms’ production data to quantify total factor productivity, demand and markups, and show how they are correlated with each other across time and with measures obtained from other approaches. In doing so, we find quantity total factor productivity and demand to be strongly negatively correlated with each other, so suggesting a trade-off between the quality of a firm’s products and their production cost. We also show how our framework provides deeper and sharper insights on the response of firms to increasing import competition from China. In particular, we find that changes in revenue productivity materialise as the outcome of complex and sometimes offsetting changes in quantity total factor productivity, demand, markups and production scale.
我们开发了一个新的框架,同时允许恢复需求、数量、全要素生产率和企业间加价的异质性,同时使三个维度之间的相关性不受限制。我们通过明确地引入需求异质性和系统地利用在以前的生产力估计方法中使用的假设来实现这一点。在此过程中,我们根据潜在的异质性提供了收入生产率的精确分解,从而弥合了数量和收入生产率估计之间的差距。我们使用比利时公司的生产数据来量化全要素生产率、需求和加价,并显示它们如何随时间相互关联,并与从其他方法获得的措施相关联。在这样做的过程中,我们发现数量全要素生产率和需求之间存在强烈的负相关关系,因此表明企业产品质量与其生产成本之间存在权衡关系。我们还展示了我们的框架如何为企业应对来自中国的进口竞争提供更深入、更清晰的见解。特别是,我们发现收入生产率的变化是数量、全要素生产率、需求、加价和生产规模的复杂变化(有时是相互抵消的变化)的结果。

Abstract This paper provides novel evidence for links between historic farming practices and current norms of cooperative behaviour. We hypothesise that the cooperation required in wetland rice farming gives rise to strong cultural norms of cooperativeness. We compare participants from prefecture cities that predominately practice wetland rice cultivation to those from non-rice regions. A public goods game with and without punishment is the main measure for cooperative behaviour. Results indicate a strong and robust positive effect of wetland rice farming on cooperative behaviour and pro-social punishment. Complementary, consistent evidence from a natural field experiment and a survey further enriches our data.
摘要本文为历史农业实践与当前合作行为规范之间的联系提供了新的证据。我们假设,湿地水稻种植所需的合作产生了强烈的合作文化规范。我们比较了主要种植湿地水稻的地级市和非水稻地区的参与者。有无惩罚的公共产品博弈是衡量合作行为的主要尺度。研究结果表明,湿地水稻种植对合作行为和亲社会惩罚有很强的正向影响。来自自然野外实验和调查的补充、一致的证据进一步丰富了我们的数据。

Abstract How does a citizen’s decision to participate in political activism depend on the participation of others? We conduct a nationwide natural field experiment in collaboration with a major European party during a recent national election. In a party survey, we randomly provide canvassers with true information about the canvassing intentions of their peers. When learning that more peers participate in canvassing than previously believed, canvassers significantly reduce both their canvassing intentions and behaviour. An additional survey among party supporters underscores the importance of free-riding motives and reveals that there is strong heterogeneity in motives underlying supporters’ behavioural responses.
公民参与政治活动的决定如何取决于他人的参与?在最近的一次全国选举中,我们与一个主要的欧洲政党合作,在全国范围内进行了一次自然实地试验。在一项政党调查中,我们随机向拉票者提供有关其同伴拉票意图的真实信息。当得知参与拉票的同伴比之前认为的要多时,拉票者会显著减少他们的拉票意图和行为。另一项针对政党支持者的调查强调了搭便车动机的重要性,并揭示了支持者行为反应背后的动机存在很强的异质性。

Designing Effective Teacher Performance Pay Programs: Experimental Evidence from Tanzania* 设计有效的教师绩效薪酬方案:来自坦桑尼亚的实验证据*

Abstract We use a nationally representative field experiment in Tanzania to compare two teacher performance pay systems in public primary schools: a ‘pay-for-percentile’ system (a rank-order tournament) and a ‘levels’ system that features multiple proficiency thresholds. Pay for percentile can potentially induce socially optimal effort among teachers, while levels systems can encourage teachers to focus on students near passing thresholds. Despite the theoretical advantage of the tournament system, we find that both systems improved student test scores across the distribution of initial learning levels after two years. However, the levels system is easier to implement and is more cost effective.
摘要:我们在坦桑尼亚进行了一项具有全国代表性的实地实验,比较了公立小学的两种教师绩效薪酬制度:“百分位数薪酬”制度(排名顺序锦标赛)和具有多个熟练程度阈值的“水平”制度。按百分位数付费可以潜在地促使教师做出社会最优努力,而等级制度可以鼓励教师关注接近及格门槛的学生。尽管比赛系统在理论上具有优势,但我们发现两年后,这两种系统都提高了学生在初始学习水平分布中的考试成绩。然而,等级系统更容易实施,成本效益更高。

Abstract We assess the career earnings losses that individual Swedish workers suffered when their occupations’ employment declined. High-quality data allow us to overcome sorting into declining occupations on various attributes, including cognitive and non-cognitive skills. Our estimates show that occupational decline reduced mean cumulative earnings from 1986–2013 by no more than 2%–5%. This loss reflects a combination of reduced earnings conditional on employment, reduced years of employment and increased time spent in unemployment and retraining. While on average workers successfully mitigated their losses, those initially at the bottom of their occupations’ earnings distributions lost up to 8%–11%.
摘要我们评估职业收入损失,个人瑞典工人遭受当他们的职业就业下降。高质量的数据使我们能够克服根据各种属性(包括认知和非认知技能)对衰退职业进行分类的问题。我们的估计表明,从1986年到2013年,职业衰退使平均累积收入减少了不超过2%-5%。这一损失反映了以就业为条件的收入减少、就业年数减少以及用于失业和再培训的时间增加的综合情况。虽然平均而言,工人们成功地减轻了损失,但那些最初处于职业收入分配底部的人的损失高达8%-11%。

Abstract Safety net programs, common in settings with high informality like Latin America, often use a means test to establish eligibility. We ask: in settings in which organised crime provides lucrative opportunities in the informal market, will discouraging formal employment via benefits eligibility criteria increase criminal enterprise activity? We link administrative socioeconomic microdata with the universe of arrests in Medellín over a decade, and exploit exogenous variation in formal-sector employment around a socioeconomic-score cutoff, below which individuals receive generous benefits if not formally employed. Regression discontinuity estimates confirm this policy reduced formal-sector employment and generated a corresponding increase in arrests associated with organised crime. We do not find increases for crimes unlikely to be associated with organised entities, such as crimes of impulse or opportunity. Effects on arrests are strongest in neighbourhoods where organised crime is most prevalent.
安全网项目在拉丁美洲等非正式性较高的地区很常见,通常使用经济状况调查来确定资格。我们的问题是:在有组织犯罪在非正式市场上提供有利可图的机会的情况下,通过福利资格标准阻止正式就业是否会增加犯罪企业活动?我们将行政社会经济微观数据与Medellín十多年来的逮捕范围联系起来,并利用社会经济得分截止点附近正式部门就业的外生变化,低于该截止点的个人如果没有正式就业,则可以获得丰厚的福利。回归不连续估计证实,这一政策减少了正规部门的就业,并导致与有组织犯罪有关的逮捕相应增加。我们没有发现不太可能与有组织实体相关的犯罪增加,例如冲动犯罪或机会犯罪。在有组织犯罪最猖獗的地区,逮捕效果最强。

Abstract We investigate which form of corporate culture is most effective in enhancing individual performance in creative tasks conducted in group settings. We combine a series of experiments with a questionnaire on corporate values to test whether performance ranking and incentives succeed in instantiating a creative corporate culture. Being ranked against competitors and setting incentives at the group level serves as a social cue that appears to induce in members a significantly stronger pro-social attitude. When this attitude is shared by group members, a social norm of high effort emerges, and creative performance is significantly higher.
摘要:我们研究了哪种形式的企业文化在团队环境下进行创造性任务时最有效地提高个人绩效。我们将一系列实验与企业价值观问卷相结合,以测试绩效排名和激励措施是否能成功地体现出一种创造性的企业文化。与竞争对手进行排名,并在群体层面设置激励措施,作为一种社会暗示,似乎会诱导成员产生明显更强的亲社会态度。当这种态度被团队成员所分享时,一种高度努力的社会规范就会出现,创造性表现也会显著提高。
