To avoid electric-infrastructure-induced wildfires, millions of Californians had their power cut for hours to days at a time. We show that rooftop solar-plus-battery-storage systems increased in zip codes with the longest power outages. Rooftop solar panels alone will not help a household avert outages, but a solar-plus-battery-storage system will. Using this fact, we obtain a revealed-preference estimate of the willingness to pay for electricity reliability, the Value of Lost Load, a key parameter for electricity market design. Our estimate, with an average of $4,980/MWh, suggests California’s wildfire-prevention outages resulted in losses from foregone consumption of $406 million to residential electricity consumers.
为避免因电力基础设施引发野火,数百万加州人被断电数小时至数天不等。我们的研究表明,在停电时间最长的邮政编码中,屋顶太阳能加电池存储系统的数量有所增加。单靠屋顶太阳能电池板无法帮助家庭避免停电,但太阳能加蓄电池系统却可以。利用这一事实,我们获得了电力可靠性支付意愿的显性偏好估计值,即电力市场设计的关键参数--损失负荷值。我们估算的平均值为 4,980 美元/兆瓦时,这表明加州因预防野火而造成的停电给居民电力消费者带来了 4.06 亿美元的损失。

We propose a simple utility framework and design a novel two-part experiment to study the relevance of personal norms across various economic games and settings. We show that personal norms — together with social norms and monetary payoff — are highly predictive of individuals’ behavior. Moreover, they are: (i) distinct from social norms across a series of economic contexts; (ii) robust to an exogenous increase in the salience of social norms; and (iii) complementary to social norms in predicting behavior. Our findings support personal norms as a key driver of economic behavior.
我们提出了一个简单的效用框架,并设计了一个新颖的两部分实验来研究个人准则在各种经济游戏和环境中的相关性。我们的研究表明,个人准则与社会准则和货币报酬一起,对个人行为具有很强的预测性。此外,它们还(i) 在一系列经济环境中与社会规范截然不同;(ii) 对社会规范显著性的外生增加具有稳健性;(iii) 在预测行为方面与社会规范相辅相成。我们的研究结果支持个人准则成为经济行为的关键驱动因素。

Assessment-led school reforms are a central pillar of policy packages recommended to address low student achievement in developing countries. We use direct audit evidence to assess the truthfulness of official assessments in a reform that has tested over 6 million students annually since 2011 in the large Indian state of Madhya Pradesh. Comparing responses to the same test questions by the same students shows a doubling of reported achievement in administrative data versus independent tests. This difference is lower, within schools, in grades with multiple test booklets and external grading. Overall, in contexts with weak governance, interventions relying on test-based accountability appear unlikely to succeed without complementary investments to assure data integrity.
以评估为主导的学校改革是发展中国家为解决学生成绩低下问题而推荐的一揽子政策的核心支柱。自 2011 年以来,印度中央邦每年对 600 多万名学生进行测试,我们利用直接审计证据来评估官方评估改革的真实性。比较相同学生对相同测试问题的回答,结果显示,行政数据与独立测试相比,报告的成绩翻了一番。在学校内部,这种差异在有多种测试卷和外部评分的年级较小。总之,在治理薄弱的情况下,如果没有确保数据完整性的辅助投资,依靠考试问责的干预措施似乎不太可能取得成功。

In several countries, students who fail high-stakes exams at the end of high school are faced with the choice of retaking or forgoing postsecondary education. We explore exogenous variation generated by a policy that imposed a performance threshold for admission into postsecondary education in Greece to estimate the effect of retaking exams on the exam performance and various measures of the quality of received offers. Using a fuzzy regression discontinuity design and novel administrative data, we find that low-achieving students who retake national exams improve their performance by around 0.6 standard deviation. We also find that they obtain higher quality postsecondary offers, thanks to improved performance and more ambitious re-application choices.
在一些国家,高中毕业时未能通过高考的学生面临着重考或放弃中学后教育的选择。我们探讨了希腊对中学后教育录取设置成绩门槛的政策所产生的外生变化,以估计重考对考试成绩的影响以及对录取质量的各种衡量标准。利用模糊回归不连续设计和新颖的行政数据,我们发现重考国家考试的低成绩学生的成绩提高了约 0.6 个标准差。我们还发现,由于成绩的提高和更大胆的重新申请选择,他们获得了更高质量的中学后录取通知书。

Effect of a transfer shock on subnational debt: Micro evidence from Mexico 转移冲击对国家以下各级债务的影响:墨西哥的微观证据

This paper examines how a shock to the distribution of federal transfers to Mexican municipalities affects their demand for long-term loans aimed at funding productive investments. Transfers are municipalities’ main source of debt payment and collateral. Using granular supervisory data, I find a positive effect on municipalities’ loan volume, normalized by the country’s total municipal loans, driven by obligations with private lenders. However, I find little or no average effect on take-up — despite many governments being unbanked —, repayment, or volume at the intensive margin. Governments with lower payment capacity and other preexisting debt are more sensitive to the shock. In particular, those with short-term debt are more likely to start borrowing from private lenders, while those with bonds turn to the development bank. The additional revenue mostly funds current rather than capital expenditures. These findings highlight that the policy goal of deepening subnational credit markets in developing countries must also address weaknesses in local investment capacities.
本文探讨了对墨西哥各市联邦转移支付分配的冲击如何影响其对旨在为生产性投资提供资金的长期贷款的需求。转移支付是市政当局偿债和抵押的主要来源。通过使用细粒度的监管数据,我发现对市政当局的贷款额有积极影响(按全国市政当局贷款总额归一化计算),这是由与私人贷款人的债务驱动的。然而,我发现,尽管许多政府没有银行账户,但在密集边际上,对接受贷款、还款或贷款额的平均影响很小或没有影响。支付能力较低和存在其他债务的政府对冲击更为敏感。尤其是那些有短期债务的政府更有可能开始向私人贷款机构借款,而那些有债券的政府则转向开发银行。额外收入主要用于经常性支出,而不是资本支出。这些发现突出表明,发展中国家深化国家以下一级信贷市场的政策目标还必须解决地方投资能力薄弱的问题。

Uneven recessions and optimal firm subsidies 不均衡的衰退和最佳企业补贴

How should policymakers distribute firm subsidies when supply shocks hit some firms and spill over to others through demand externalities? I propose a model to answer that question. The optimal policy depends on the severity of the supply shock and the degree of substitution across goods. If shocks are not too large or widespread, it is optimal to subsidize only firms not hit by supply shocks. For larger and more widespread shocks, the results depend on the elasticity of substitution: If complementarities across the varieties produced by firms are high, firms facing supply shocks should be prioritized, and the opposite is true if complementarities are low.
当一些企业受到供给冲击,并通过需求外部性波及其他企业时,政策制定者应如何分配企业补贴?我提出了一个模型来回答这个问题。最佳政策取决于供应冲击的严重程度和商品之间的替代程度。如果冲击不太大或范围不太广,最佳的做法是只对未受供应冲击的企业提供补贴。对于较大和较普遍的冲击,结果取决于替代弹性:如果企业生产的产品种类之间的互补性较高,则应优先考虑面临供应冲击的企业;如果互补性较低,则应优先考虑面临供应冲击的企业。

This paper assesses the effect of the creation of specialised intimate partner violence (IPV) courts on the reporting of IPV, and the incidence of IPV homicides in Spain. We find that the opening of a specialised IPV court increases the reporting of IPV by nearly 122 offences per 100,000 inhabitants, or 28% in the preferred specification. The rise in reporting is primarily driven by an increase in the reporting of moderate offences. We do not find conclusive evidence on the effects of specialised courts on IPV homicides.
本文评估了在西班牙设立专门的亲密伴侣暴力(IPV)法庭对 IPV 举报和 IPV 凶杀案发生率的影响。我们发现,开设专门的亲密伴侣暴力法庭后,每 10 万名居民中的亲密伴侣暴力报案率增加了近 122 起,在首选规范中增加了 28%。报案量的增加主要是由于中度犯罪报案量的增加。我们没有发现关于专门法庭对 IPV 凶杀案影响的确凿证据。

I investigate the labor supply effects of the introduction of an exceptionally large unconditional cash benefit. I exploit the unique design of the child benefit program in Poland to identify the effects of the monthly transfer in a difference-in-differences design. The transfer had no short-term effects but caused sizable negative medium-term effects on household labor supply. In the medium run, population estimates indicate that for every extra 100 dollars in monthly child benefit transfers households received, they reduced their after-tax earnings by 25 dollars, spent 32 dollars on consumption, and saved 43 dollars. These negative labor supply effects are much larger and much more precisely estimated among households with low socioeconomic status. Additional evidence shows that the program had a positive impact on investments in human capital and home production efficiency.
我研究了引入特别大额无条件现金福利对劳动力供给的影响。我利用波兰儿童福利项目的独特设计,通过差分设计来确定每月转移支付的效果。转移支付没有短期影响,但对家庭劳动力供给产生了可观的中期负面影响。从中期来看,人口估计表明,家庭每月每多收到 100 美元的儿童福利转移支付,他们的税后收入就会减少 25 美元,消费支出减少 32 美元,储蓄减少 43 美元。在社会经济地位较低的家庭中,这些对劳动力供给的负面影响要大得多,估计的结果也要精确得多。其他证据表明,该计划对人力资本投资和家庭生产效率产生了积极影响。

We investigate the unintended impact of minimum wage increases on workplace safety. Using establishment-level data from the United States and a cohort-based stacked difference-in-differences design, we find that large increases in minimum wages have significant adverse effects on workplace safety. Our findings indicate that, on average, a large minimum wage increase results in a 4.6 percent increase in the total case rate. Event study estimates show that this adverse effect persists in the medium run. Furthermore, we find a more salient effect for firms more likely to be financially constrained or subject to a higher labor market rigidity in firing workers. We provide suggestive evidence that small minimum wage increases might reduce injury rates, highlighting the potential heterogeneity in the impact of minimum wage changes. We do not find evidence that capital-labor substitution could be behind the findings.
我们研究了提高最低工资对工作场所安全的意外影响。利用美国的机构级数据和基于队列的堆叠差分设计,我们发现最低工资的大幅提高对工作场所安全有显著的不利影响。我们的研究结果表明,平均而言,最低工资的大幅提高会导致总案件率上升 4.6%。事件研究的估计结果表明,这种不利影响会在中期持续存在。此外,我们还发现,对于那些更有可能受到财务限制或在解雇工人时受到劳动力市场更高的刚性约束的企业来说,这种影响更为显著。我们提供了小幅提高最低工资可能会降低工伤率的提示性证据,凸显了最低工资变化影响的潜在异质性。我们没有发现证据表明这些发现背后可能存在资本-劳动力替代。

The long run impact of childhood interracial contact on residential segregation 儿童时期的种族间接触对居住隔离的长期影响

This paper exploits quasi-random variation in the share of Black students across cohorts within US schools to investigate whether childhood interracial contact impacts the residential choices of Whites when they are adults. We find that, 20 years after exposure, Whites who had more Black peers of the same gender in their grade go on to live in census tracts with more Black residents. Further investigation suggests that this result is unlikely to be driven by economic opportunities or social networks. Instead, the effect on residential choice appears to come from a change in preferences among Whites.
本文利用美国学校不同年级黑人学生比例的准随机变化,研究童年时期的种族间接触是否会影响白人成年后的居住选择。我们发现,在接触黑人同学 20 年后,年级中有更多同性黑人同学的白人会居住在有更多黑人居民的人口普查区。进一步的调查表明,这一结果不太可能是由经济机会或社会网络驱动的。相反,对居住选择的影响似乎来自于白人偏好的改变。

We find that, 20 years after exposure, Whites who had more Black peers of the same gender in their grade go on to live in census tracts with more Black residents. Further investigation suggests that this result is unlikely to be driven by economic opportunities or social networks. Instead, the effect on residential choice appears to come from a change in preferences among Whites.</div></div>","PeriodicalId":48436,"journal":{"name":"Journal of Public Economics","volume":"239 ","pages":"Article 105242"},"PeriodicalIF":4.8,"publicationDate":"2024-10-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142423881","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
