Hurricanes are considered among the most destructive natural disasters in the United States. The exposure of agricultural production systems to hurricanes varies between regions in contrast to global risks like commodity price volatility and international trade policies. The regional differences in hurricane exposure may lead to heterogeneity in crop insurance premium rates. This work aims to measure the impact of hurricane incidence on production losses for crops grown in the Mississippi Delta. We leverage a county-month panel of insurance losses spanning 2002–2021 from the US Department of Agriculture Risk Management Agency, and daily data from the National Oceanic and Atmospheric Administration National Hurricane Center, to construct novel measures for hurricane treatment assignment under a difference-in-differences identification strategy. We find hurricane incidence results in economically significant losses that are strikingly heterogeneous across crops. We also demonstrate that measuring hurricane treatment is a critical concern for credible identification as simplistic approaches are associated with attenuation bias relative to our approach which accounts for the dynamic changes in the scope and intensity of a hurricane. We discuss implications of these results for two important policy instruments, traditional crop insurance premium rating and the more recently released Hurricane Insurance Protection—Wind Index product.

飓风被认为是美国最具破坏性的自然灾害之一。与大宗商品价格波动和国际贸易政策等全球风险相比,农业生产系统受飓风影响的程度因地区而异。飓风风险的区域差异可能导致农作物保险费率的异质性。这项工作旨在衡量飓风对密西西比三角洲作物生产损失的影响。我们利用美国农业部风险管理局2002年至2021年间的县月保险损失面板,以及国家海洋和大气管理局国家飓风中心的每日数据,在差异中差异识别策略下构建飓风处理分配的新措施。我们发现飓风的发生会导致经济上的重大损失,而这些损失在不同作物之间有着显著的异质性。我们还证明,测量飓风处理是可靠识别的关键问题,因为相对于我们的方法,简化方法与衰减偏差有关,这种方法解释了飓风范围和强度的动态变化。我们讨论了这些结果对两种重要政策工具的影响,即传统的农作物保险保费评级和最近发布的飓风保险保护-风指数产品。

We study racial differences in internal migration responses to one of the most severe climatic shocks in US history—the drought of the 1930s. Using data from the 1940 census on 70 million adults, we find that individuals exposed to more severe drought between 1935 and 1940 were more likely to make an inter-county move and that this responsiveness was greater for Black individuals than White individuals. This racial difference was particularly pronounced among the rural population. Black individuals' migration premium came despite their systematic disadvantage in the economy of the 1930s and evidence along dimensions other than race that disadvantage limited individuals' ability to adapt to the drought through migration. Federal relief spending under the Agricultural Adjustment Act (AAA) magnified this racial difference, reducing the migration response to drought for White individuals and increasing it for Black individuals. These results help to better understand how the reactions of different groups aggregate to determine the magnitude and composition of migration responses to natural disasters, as well as the roles of migration and government policy in disadvantaged groups' responses to natural disasters.

我们研究了美国历史上最严重的气候冲击之一——20世纪30年代的干旱——在国内移民反应中的种族差异。利用1940年对7000万成年人的人口普查数据,我们发现,1935年至1940年间遭受更严重干旱的个体更有可能进行跨县迁移,而且这种反应在黑人个体中比白人个体更大。这种种族差异在农村人口中尤为明显。尽管黑人在20世纪30年代的经济中处于系统性劣势,并且有证据表明,除了种族之外,其他方面的劣势限制了个人通过移民适应干旱的能力,但他们的移民溢价还是出现了。《农业调整法案》(AAA)下的联邦救济支出放大了这种种族差异,减少了白人对干旱的迁移反应,增加了黑人对干旱的迁移反应。这些结果有助于更好地理解不同群体的反应如何共同决定移民对自然灾害的反应程度和构成,以及移民和政府政策在弱势群体对自然灾害的反应中所起的作用。

Balancing conflicting policy goals is a key challenge in the transition to sustainable agricultural systems. An important example is herbicide use reduction potentially conflicting with conservation tillage—which often strongly relies on herbicide use. We investigate the joint uptake of two agri-environmental schemes, conservation tillage and herbicide-free agriculture systems. To this end, we use a combination of detailed survey data on farmer behavior, environmental and agronomic data, and census data on the complete population of all farmers from Switzerland. Findings based on a multinomial logit and fixed effects multinomial logit indicate that, conditional on observable factors, the systems are not complementary, but joint adoption occurs for 35% of farmers. Behavioral factors explain 26% of joint adoption behavior, emphasizing the role of risk taking, openness to innovation, and biodiversity valuations in farmers' decisions. Our analysis provides broader implications for assessing and navigating conflicting sustainability goals in agriculture globally.

平衡相互冲突的政策目标是向可持续农业系统过渡的一项关键挑战。一个重要的例子是,减少除草剂的使用可能与保护性耕作相冲突,保护性耕作往往严重依赖除草剂的使用。我们研究了两种农业环境方案,保护性耕作和无除草剂农业系统的联合吸收。为此,我们结合了农民行为的详细调查数据、环境和农艺数据以及瑞士所有农民的人口普查数据。基于多项logit和固定效应多项logit的研究结果表明,在可观察因素的条件下,两种制度不是互补的,但35%的农民会联合采用。行为因素解释了26%的共同采用行为,强调了风险承担、创新开放和生物多样性评估在农民决策中的作用。我们的分析为评估和引导全球农业中相互冲突的可持续发展目标提供了更广泛的意义。

Farm delinquency is linked to many negative indicators of farm survival, including increased risk of bankruptcy and farm failure. Minority farmers and ranchers (MFR) have been found to exhibit higher rates of delinquency on U.S. Department of Agriculture (USDA) Farm Service Agency (FSA) loans compared to their non-Hispanic White male counterparts. These findings persist even after accounting for economic/financial factors expected to predict loan repayment performance. In this study, to further explore the existing discrepancy between loan default rates for MFR and White, non-Hispanic borrowers, we look more broadly than financial indicators and introduce MFR representation on the FSA County Office Committee (COC) as a proxy for the local cultural climate in an agricultural community. Using changes in COC membership demographics over time and across counties, this study suggests that MFR representation on the COC is associated with a lower probability of MFR delinquency by roughly 10 percentage points. With the probability of delinquency also being about 10 percentage points higher among MFR, the effect represents a significant improvement in loan repayment outcomes for the group. The FSA COCs represent an important linkage between the USDA and the local agricultural community. Moreover, elected minority representation on COCs can be considered as indicative of supportive cultural climates for minorities in agriculture. Given that COC membership composition may represent a proxy for local cultural climate in agriculture, this research raises interesting questions about the potential relationship of MFR representation and community engagement, to FSA program performance.

农场拖欠与农场生存的许多负面指标有关,包括破产和农场倒闭的风险增加。与非西班牙裔白人男性相比,少数族裔农民和牧场主(MFR)在美国农业部(USDA)农场服务局(FSA)贷款中表现出更高的拖欠率。即使在考虑了预计会预测贷款偿还表现的经济/金融因素后,这些发现仍然存在。在本研究中,为了进一步探讨MFR与白人、非西班牙裔借款人的贷款违约率之间存在的差异,我们的研究范围比财务指标更广泛,并引入了MFR在FSA县办公室委员会(COC)中的代表性,作为农业社区当地文化气候的代表。利用COC成员人口统计数据随时间和郡县的变化,本研究表明,COC中MFR的代表与MFR犯罪概率降低了大约10个百分点有关。由于MFR的拖欠概率也高出约10个百分点,该效应表明该群体在贷款偿还结果方面有显著改善。FSA COCs代表了美国农业部和当地农业社区之间的重要联系。此外,委员会中选出的少数民族代表可以被认为是对农业少数民族的支持性文化气候的指示。鉴于COC成员组成可能代表了当地农业文化气候的代表,本研究提出了关于MFR代表和社区参与与FSA计划绩效之间潜在关系的有趣问题。

Understanding the impacts of environmental conditions is critical for shaping policies aimed at improving human capital outcomes in developing contexts. This study utilizes individual-level data on children from Pakistan to investigate the impact of rainfall shocks, from the in-utero stage to age 16, on human capital development. The results reveal that positive rainfall shocks reduce cognitive performance in older children (ages 11–16), as their school attendance declines and their participation in labor increases. In contrast, younger children (ages 5–10) are mostly unaffected. Positive rainfall shocks during school transition and early teenage years (ages 11–16) reduce the overall educational attainment among young adults (ages 16–30) and increase the likelihood of marriage between ages 18 and 24. Conversely, children born during years of positive rainfall shocks exhibit improved physical and cognitive development, and are less likely to engage in child marriage or child labor. These long-term effects are especially pronounced among girls.

了解环境条件的影响对于制定旨在改善发展中国家人力资本成果的政策至关重要。本研究利用巴基斯坦儿童的个人数据,调查从胎儿期到16岁的降雨冲击对人力资本发展的影响。结果显示,积极的降雨冲击降低了年龄较大的儿童(11-16岁)的认知表现,因为他们的入学率下降,参与劳动的人数增加。相比之下,年龄较小的儿童(5-10岁)大多不受影响。在学校过渡时期和青少年早期(11-16岁)的积极降雨冲击降低了年轻人(16-30岁)的总体受教育程度,并增加了18至24岁之间结婚的可能性。相反,在积极降雨年份出生的儿童表现出更好的身体和认知发展,并且不太可能从事童婚或童工。这些长期影响在女孩中尤为明显。

Smallholder farmers in low- and middle-income countries face several constraints to technology adoption. We test the relative efficacy of interventions designed to incentivize the production and consumption of a biofortified orange-fleshed sweet potato crop by female farmers in Uganda. Through a clustered randomized controlled trial involving more than 8000 female farmers across 210 communities, we track the impact of the interventions on adoption, consumption, and health outcomes, both in the short term and long term. Our findings suggest that the provision of inputs and agricultural extension is an effective approach to adoption, leading over 60% of households to cultivate and 50% to consume the crop. Nutrition training emphasizing the crop's health benefits has limited impact on cultivation, but it leads 20% of households to consume the biofortified crop. Combining the two approaches with supplementary credit and insurance products has limited marginal effects on adoption. We also observe improvements in dietary diversity resulting from the tested interventions, along with spillover effects through social networks in neighboring communities. We find little evidence of treatment effects on higher-order outcomes such as visual acuity, child health and nutrition, or income.

低收入和中等收入国家的小农在采用技术方面面临若干限制。我们测试了旨在激励乌干达女性农民生产和消费生物强化橙肉甘薯作物的干预措施的相对功效。通过一项涉及210个社区8000多名女性农民的聚类随机对照试验,我们跟踪了干预措施对短期和长期采用、消费和健康结果的影响。我们的研究结果表明,提供投入和农业推广是一种有效的采用方法,导致超过60%的家庭种植作物,50%的家庭消费作物。强调作物健康益处的营养培训对种植的影响有限,但它使20%的家庭消费生物强化作物。将这两种方法与补充信贷和保险产品相结合,对采用的边际效应有限。我们还观察到,经过测试的干预措施改善了饮食多样性,并通过邻近社区的社会网络产生了溢出效应。我们发现很少有证据表明治疗对高阶结果(如视力、儿童健康和营养或收入)有影响。

Many fish consumers reveal a preference for sustainably sourced seafood in their purchasing decisions. We propose a bioeconomic modeling approach and an empirical strategy, based on a discrete choice experiment, to quantify the resulting effects on fishery dynamics and to derive implications for efficient fishery management. We show that a “consumer stock effect” arises, which stabilizes a fishery under open access and which decreases catches under economically efficient management. We quantify these effects for the Western Baltic cod fishery.

许多鱼类消费者在购买决定中表现出对可持续来源海鲜的偏好。我们提出了一种基于离散选择实验的生物经济建模方法和经验策略,以量化对渔业动态的影响,并得出有效渔业管理的启示。我们的研究表明,“消费存量效应”产生了,它稳定了开放获取下的渔业,并在经济有效的管理下减少了渔获量。我们量化了这些对西波罗的海鳕鱼渔业的影响。

Women's work and agricultural productivity gaps in India 印度妇女的工作和农业生产力差距

Most studies on gender gaps in agricultural productivity leverage within-household differences between plots managed by women and men. Such a gender-based division of plot management simplifies empirical tests for productivity differences, but it is not a common arrangement outside some locations in sub-Saharan Africa. In most rural households, women and men jointly participate in production, complicating the identification of gender-based productivity differences. This study proposes a broader empirical test of productivity gaps that applies to such systems and is rooted in gender-based inequities rather than gender per se. We explore productivity gaps in rice-cultivating Indian households, where women and men perform distinct cultivation tasks. We measure productivity gaps based on the differential use of family and hired female labor across households and then compare them with gaps based on the differential use of family and hired male labor. Using plot-level data, we identify significant gender-based productivity gaps after controlling for input use and plot- and household-level characteristics, along with using village fixed effects and machine learning estimators to address selection and model misspecification concerns. We find that households using family female labor have lower agricultural productivity than those also hiring female workers, such that forgone production value is greater than the cost of hiring women. We find suggestive evidence that this gap stems from skill differences between hired and family female workers. In contrast, we find no similar gap regarding male labor use. Overall, household welfare is lower because of gender-based inequities, and highlights the potential productivity implications of expanding women's labor choices in both on- and off-farm roles.

大多数关于农业生产力性别差距的研究都利用了家庭内女性和男性管理地块之间的差异。这种基于性别的地块管理划分简化了对生产力差异的经验检验,但在撒哈拉以南非洲的一些地区之外,这并不是一种常见的安排。在大多数农村家庭中,妇女和男子共同参与生产,使确定基于性别的生产力差异变得更加复杂。本研究提出了适用于此类制度的生产率差距的更广泛的实证检验,其根源在于基于性别的不平等,而不是性别本身。我们探讨了印度种植水稻家庭的生产力差距,在这些家庭中,女性和男性从事不同的种植任务。我们根据不同家庭使用家庭和雇佣女性劳动力的差异来衡量生产率差距,然后将其与基于家庭和雇佣男性劳动力使用差异的差距进行比较。利用地块水平数据,我们在控制投入使用、地块和家庭水平特征后,确定了显著的基于性别的生产力差距,并使用村庄固定效应和机器学习估计器来解决选择和模型错误规范问题。我们发现,使用家庭女性劳动力的家庭的农业生产率低于同时雇佣女性劳动力的家庭,因此放弃的生产价值大于雇佣女性的成本。我们发现了暗示性的证据,表明这种差距源于雇佣女工和家庭女工之间的技能差异。相比之下,我们发现在男性劳动力使用方面没有类似的差距。总体而言,由于基于性别的不平等,家庭福利较低,并突出了扩大妇女在农场和非农岗位上的劳动选择对生产力的潜在影响。

Such a gender-based division of plot management simplifies empirical tests for productivity differences, but it is not a common arrangement outside some locations in sub-Saharan Africa. In most rural households, women and men jointly participate in production, complicating the identification of gender-based productivity differences. This study proposes a broader empirical test of productivity gaps that applies to such systems and is rooted in gender-based inequities rather than gender per se. We explore productivity gaps in rice-cultivating Indian households, where women and men perform distinct cultivation tasks. We measure productivity gaps based on the differential use of family and hired female labor across households and then compare them with gaps based on the differential use of family and hired male labor. Using plot-level data, we identify significant gender-based productivity gaps after controlling for input use and plot- and household-level characteristics, along with using village fixed effects and machine learning estimators to address selection and model misspecification concerns. We find that households using family female labor have lower agricultural productivity than those also hiring female workers, such that forgone production value is greater than the cost of hiring women. We find suggestive evidence that this gap stems from skill differences between hired and family female workers. In contrast, we find no similar gap regarding male labor use.

Using data on the site choices of marine recreational anglers fishing in the Gulf of Mexico, we build on previous literature that finds anglers are willing to encumber travel costs to avoid sites located in areas with more predominant Black and Hispanic populations. Upon exploring the nature of this discrimination, we find results that are consistent with the predictions of statistical discrimination theory, as more experienced anglers discriminate less than less experienced anglers. We also find some results consistent with taste-based discrimination, as we observe different degrees of discrimination among anglers from less (more) diverse trip origins. However, the evidence of taste-based discrimination disappears in analyses using a novel dataset containing angler-level race and ethnicity data. We conclude that the observed discrimination is predominantly statistical in nature, a product of a choice setting involving imperfect information that becomes less imperfect as anglers gain experience.

利用墨西哥湾海洋休闲垂钓者的地点选择数据,我们建立在先前文献的基础上,发现垂钓者愿意负担旅行费用,以避免位于黑人和西班牙裔人口较多的地区。在探索这种歧视的本质后,我们发现结果与统计歧视理论的预测一致,因为经验丰富的垂钓者比经验不足的垂钓者歧视更少。我们还发现了一些与品味歧视一致的结果,因为我们观察到来自较少(较多)不同旅行来源的垂钓者之间存在不同程度的歧视。然而,在使用包含垂钓者种族和民族数据的新数据集进行分析时,基于品味的歧视的证据消失了。我们的结论是,观察到的歧视主要是统计性质的,是一个包含不完美信息的选择设置的产物,随着垂钓者获得经验而变得不那么不完美。

Ethnic and gender disparities in U.S. agriculture: An analysis of technology and technical efficiency differentials 美国农业中的种族和性别差异:技术和技术效率差异的分析

We explore ethnic and gender disparities in U.S. agriculture by comparing productivity gaps between male- and female-headed family farms, and between non-Hispanic White and minority-headed family farms. Using Agricultural Resource Management Survey data from 2017 to 2020, propensity score matching techniques are applied to obtain comparable samples based on observable covariates. Statistical tests reveal structural differences in production technologies between male- and female-headed farms, and between non-Hispanic White and minority-headed farms, thus requiring the estimation of separate production technologies for each group. Accordingly, a stochastic metafrontier framework is used to envelop the group frontiers and assess technology gaps. The results indicate that female and minority-principal operators not only use different production technologies but are also less proficient at combining inputs to maximize farm output. The results also reveal within-group gender and ethnic differences—ceteris paribus, among non-Hispanic White and minority-led farms, female producers generated substantially less output compared to their male counterparts. Similarly, among male principal operators, Hispanic producers generated more output compared to their non-Hispanic White and non-Hispanic non-White counterparts.

我们通过比较男性和女性为户主的家庭农场以及非西班牙裔白人和少数族裔为户主的家庭农场之间的生产率差距,探讨了美国农业中的种族和性别差异。利用2017 - 2020年农业资源管理调查数据,基于可观测协变量,应用倾向得分匹配技术获得可比较样本。统计测试揭示了男性和女性当家农场之间以及非西班牙裔白人和少数族裔当家农场之间生产技术的结构性差异,因此需要对每个群体的单独生产技术进行估计。因此,采用随机元前沿框架来包络群体前沿并评估技术差距。结果表明,女性和少数民族经营者不仅使用不同的生产技术,而且在组合投入以实现农业产出最大化方面也不太精通。研究结果还揭示了群体内部的性别和种族差异——在其他条件下,在非西班牙裔白人和少数族裔主导的农场中,女性生产者的产出明显低于男性生产者。同样,在男性主要经营者中,西班牙裔生产者比非西班牙裔白人和非西班牙裔非白人生产者产出更多。
