Marriage is declining in China. Among singles, the probability of marrying in 2019 was half that of marrying in 1999. We estimate a Choo and Siow (2006b) model using census data to quantify the relative roles of changes in population structure and changes in marital surplus, i.e., the value of marriage. We find that the increase in the supply of educated people explains half of the decline, partly due to a mismatch between highly-educated women and less-educated men. The deterioration of female-to-male ratio, known as marriage squeeze, explains an additional 13% for men. The decrease in surplus accounts for the remainder.
中国的结婚率正在下降。在单身人士中,2019年结婚的可能性是1999年结婚的一半。我们使用人口普查数据估算了Choo和Siow (2006b)模型,以量化人口结构变化和婚姻剩余(即婚姻价值)变化的相对作用。我们发现,受教育人数的增加解释了一半的下降,部分原因是受过高等教育的女性和受教育程度较低的男性之间的不匹配。男女比例的恶化,即所谓的“婚姻挤压”,解释了男性多出13%的原因。剩余部分的原因是盈余的减少。

Children’s say in the household 孩子们在家里说了算
IF 4.6 1区 经济学 Q1 ECONOMICS Pub Date : 2026-02-01 Epub Date: 2025-11-24 DOI: 10.1016/j.jdeveco.2025.103689

Analyzing children’s agency is crucial for understanding the inner workings of households. This issue is especially salient for developing countries, as childless families constitute a small portion of the population. This study tests the intra-household decision-making power of work-eligible children (age 12–17) in rural Bangladesh using a restriction implied by the collective household model. By comparing households with working and non-working children, the study also tests whether working children have a greater say in their households than non-working ones. The findings suggest some evidence for children’s decision-making power. The unitary household model is strongly rejected, and there is no evidence against Pareto efficiency. The results are particularly useful for the growing body of research that estimates intra-household inequality and individual-level poverty in developing countries using the collective model with certain assumptions on children’s decision-making power. In addition to investigating children’s say in the household, the study addresses several methodological issues in the literature regarding the price-based test of alternative collective models and Pareto efficiency.
分析儿童机构对于理解家庭内部运作至关重要。这个问题对发展中国家尤其突出,因为没有子女的家庭只占人口的一小部分。本研究使用集体家庭模型隐含的限制来测试孟加拉国农村符合工作条件的儿童(12-17岁)的家庭内部决策权。通过比较有工作和不工作的孩子的家庭,这项研究还测试了工作的孩子是否比不工作的孩子在家庭中有更大的发言权。这些发现为儿童的决策能力提供了一些证据。单一家庭模型被强烈拒绝,并且没有证据反对帕累托效率。这些结果对越来越多的研究机构特别有用,这些研究机构使用集体模型,对儿童的决策权进行某些假设,估计发展中国家家庭内部的不平等和个人一级的贫困。除了调查儿童在家庭中的发言权外,该研究还解决了文献中关于基于价格的替代集体模型和帕累托效率测试的几个方法学问题。

Air pollution and manufacturing productivity: Understanding the roles of technology and adaptation 空气污染与制造业生产力:了解技术和适应的作用
IF 4.6 1区 经济学 Q1 ECONOMICS Pub Date : 2026-02-01 Epub Date: 2025-09-15 DOI: 10.1016/j.jdeveco.2025.103597

I analyze the impact of air pollution on manufacturing productivity in India, examining how technology and adaptation influence the damages. Using firm panel and satellite-derived pollution data, I estimate the effect of pollution on productivity, with wind velocity serving as an instrument for air pollution. While sensitivity is detected among labor-intensive industries, no meaningful average effect is found. To explain these patterns, I present a model showing that firms adapt by lowering output to mitigate pollution damages and that industries’ production technology contributes to heterogeneity. Applying the model, I estimate that a one standard deviation increase in the labor intensity of production technology results in a 0.6 percentage point greater negative impact of pollution on productivity. The findings imply that the damages of pollution to profits are twice as high among adversely affected industries than the average and four times higher when inputs remain fixed relative to when they adapt.
我分析了空气污染对印度制造业生产力的影响,研究了技术和适应如何影响损害。利用固定面板和卫星导出的污染数据,我估计了污染对生产力的影响,风速作为空气污染的一种工具。虽然在劳动密集型产业中发现了敏感性,但没有发现有意义的平均效应。为了解释这些模式,我提出了一个模型,表明企业通过降低产量来减轻污染损害,而行业的生产技术有助于异质性。运用该模型,笔者估计生产技术的劳动强度每增加一个标准差,污染对生产率的负面影响就会增加0.6个百分点。研究结果表明,在受到不利影响的行业中,污染对利润的损害是平均水平的两倍,而在投入保持固定的情况下,污染对利润的损害是适应时的四倍。

We estimate the impacts of China's extensive high-speed railroads (HSR) expansions using both county-level and household-level agricultural data. Our estimates indicate that HSR expansions: (i) facilitated the outflow of labor from agriculture and reduced cropland in connected rural areas, particularly in underdeveloped regions; (ii) increased agricultural total factor productivity (TFP), effectively offsetting the negative impacts on agricultural output from reduced inputs; (iii) significantly boosted local GDP and government revenue, providing financial support for agriculture and critical investments in agricultural infrastructure and rural roads; (iv) facilitated farmers' access to technical training and encouraged the entry of new agribusiness firms; and (v) increased farmers' revenues and profits, strengthening their economic incentives for production and collectively improving agricultural TFP.
我们使用县级和家庭农业数据来估计中国高速铁路(HSR)广泛扩张的影响。我们的估计表明,高铁的扩张:(1)促进了农业劳动力的外流,减少了农村地区的耕地面积,特别是在欠发达地区;(ii)提高农业全要素生产率(TFP),有效抵消投入减少对农业产出的负面影响;(iii)显著提高了当地GDP和政府收入,为农业和农业基础设施和农村道路的关键投资提供了财政支持;便利农民获得技术培训,鼓励新的农业综合企业进入;(五)增加农民收入和利润,增强农民生产的经济激励,共同提高农业全要素生产率。

Digital revitalization or useless effort? Public e-commerce support and local specialty sales 数字复兴还是无用的努力?公共电商支持和地方特产销售
IF 4.6 1区 经济学 Q1 ECONOMICS Pub Date : 2026-02-01 Epub Date: 2025-10-14 DOI: 10.1016/j.jdeveco.2025.103665

We examine how a government-initiated e-commerce platform (GEP) affects sales of a local specialty in China’s Pu’er tea market. Using a unique dataset from field experiments and surveys of 983 farmers, we examine changes in online and offline sales over time. We employ two-way fixed effects (TWFE) models to identify the causal impact of GEP access. The results reveal significant substitution effects: access to the GEP increases online sales by 16.649% and decreases offline sales by 15.549%, indicating an overall shift from offline to online sales. On the extensive margin, households that previously sold only offline become more likely to sell online. On the intensive margin, adopters expand their online channels and offer a wider range of tea qualities. The mediation analysis suggests that the increase in online sales channels and product variety accounts for the impact of GEP access on the shift to online transactions.
我们研究了政府发起的电子商务平台(GEP)如何影响中国普洱茶市场上当地特产的销售。使用来自983名农民的实地实验和调查的独特数据集,我们研究了线上和线下销售随时间的变化。我们采用双向固定效应(TWFE)模型来确定GEP获取的因果影响。结果显示显著的替代效应:使用GEP使线上销售增加了16.649%,使线下销售减少了15.549%,表明整体销售从线下转向线上。从广泛的角度来看,以前只在线下销售的家庭更有可能在网上销售。在密集的边际上,采用者扩大了他们的在线渠道,并提供了更广泛的茶叶品质。中介分析表明,在线销售渠道和产品种类的增加是GEP访问对在线交易转移的影响。

Environmental regulation, induced innovation, and greener transition: Firm-level evidence 环境监管、诱导创新和绿色转型:企业层面的证据
IF 4.6 1区 经济学 Q1 ECONOMICS Pub Date : 2026-02-01 Epub Date: 2025-11-03 DOI: 10.1016/j.jdeveco.2025.103678

This paper examines the impact of environmental regulations on hazardous chemical use and the role of innovation in firms’ adjustment processes. Using a newly constructed dataset that links firm-level chemical usage with patent activity, we analyze the effects of Korea’s plausibly exogenous chemical safety Acts promulgated in 2015. Our findings show that firms subject to stricter regulations reduced their reliance on hazardous chemicals to comply with the new laws. Innovation plays a crucial role in this transition, facilitating a shift toward eco-friendly practices. Specifically, stricter regulations induced more firm-level innovation, and firms with greater product innovation significantly reduced their hazardous chemical usage. The effect was particularly strong among firms that use hazardous substances as intermediate inputs. These findings demonstrate that well-designed regulation can promote the principles of Green Chemistry, prevention through redesign, by driving innovation.
本文考察了环境法规对危险化学品使用的影响以及创新在企业调整过程中的作用。使用一个新构建的数据集,将企业层面的化学品使用与专利活动联系起来,我们分析了韩国2015年颁布的看似外生的化学品安全法的影响。我们的研究结果表明,受到更严格监管的公司减少了对危险化学品的依赖,以遵守新法律。创新在这一转变中发挥着至关重要的作用,促进了向环保实践的转变。具体而言,更严格的法规诱导了更多的企业层面的创新,产品创新程度更高的企业显著减少了危险化学品的使用。这种影响在使用有害物质作为中间投入的公司中尤为明显。这些发现表明,设计良好的监管可以通过推动创新来促进绿色化学原则,通过重新设计来预防。

Irrigation infrastructure and satellite-measured land cultivation impacts: Evidence from the Senegal river valley 灌溉基础设施和卫星测量的土地耕作影响:来自塞内加尔河谷的证据

Expanding irrigation in sub-Saharan Africa is widely viewed as a promising strategy for closing yield gaps and enhancing resilience to climate change. Drawing on more than 3,000 satellite images over a 30-year period, we examine the impact of irrigation infrastructure development in the Senegal River Valley. We find that cultivation rates increase substantially following irrigation project completion. Cultivation rates are remarkably stable at around 25 percentage points above pre-irrigation levels for the first 20 years, and trend even higher from years 20 to 25. Moreover, we show that crops cultivated on irrigated land are significantly less sensitive to both positive and negative temperature shocks, underscoring the role of irrigation in climate adaptation. Despite these aggregate gains, we document considerable heterogeneity in project outcomes, with intermittent land use remaining widespread. To shed light on these patterns, we complement the satellite analysis with farmer survey data, which point to persistent water access constraints as a key barrier to continuous cultivation—constraints that cannot be resolved solely through individual farmer action.
在撒哈拉以南非洲扩大灌溉被广泛认为是缩小产量差距和增强应对气候变化能力的一项有希望的战略。利用30年期间的3000多张卫星图像,我们研究了塞内加尔河谷灌溉基础设施发展的影响。我们发现,灌溉工程完成后,种植率大幅提高。前20年的种植率非常稳定,比灌溉前的水平高出约25个百分点,从第20年到第25年的趋势甚至更高。此外,我们发现灌溉土地上种植的作物对正、负温度冲击的敏感性显著降低,强调了灌溉在气候适应中的作用。尽管取得了这些总体收益,但我们发现项目结果存在相当大的异质性,间歇性土地使用仍然普遍存在。为了阐明这些模式,我们用农民调查数据对卫星分析进行了补充,这些数据表明,持续存在的取水限制是持续种植的关键障碍,而这些限制不能仅通过农民个人行动来解决。

Impact evaluations in data-scarce environments: The case of stress-tolerant rice varieties in Bangladesh 数据匮乏环境中的影响评价:孟加拉国耐应力水稻品种的案例

New technologies are sometimes introduced at times or in places that lack the necessary data to conduct a well-identified impact evaluation. We develop a methodology that combines Earth Observation (EO) data and deep learning with administrative and survey data so as to allow researchers to conduct impact evaluations when traditional economic data is missing. To demonstrate our method, we study stress tolerant rice varieties (STRVs) first introduced to Bangladesh 15 years ago. Using EO data on rice production and flooding for the entire country, spanning two decades, we find evidence of STRV effectiveness. We highlight how the nature of the technology, which is only effective under a specific set of circumstances, creates a Goldilocks Problem that EO data is particularly well suited to addressing. Our findings speak to the promises and challenges of using EO data to conduct impact evaluations in data-scarce environments.
新技术有时在缺乏必要数据进行明确确定的影响评价的时候或地方引入。我们开发了一种方法,将地球观测(EO)数据和深度学习与行政和调查数据相结合,使研究人员能够在传统经济数据缺失的情况下进行影响评估。为了证明我们的方法,我们研究了15年前首次引入孟加拉国的耐胁迫水稻品种(strv)。利用20年来全国水稻生产和洪水的EO数据,我们发现了STRV有效性的证据。我们强调了这项技术的本质,它只在特定的情况下有效,创造了一个金发姑娘问题,EO数据特别适合解决这个问题。我们的研究结果说明了在数据稀缺的环境中使用EO数据进行影响评估的前景和挑战。

Digitalization as a double-edged sword: Winning services and losing manufacturing in India 数字化是一把双刃剑:印度服务业赢了,制造业输了
IF 4.6 1区 经济学 Q1 ECONOMICS Pub Date : 2026-02-01 Epub Date: 2025-09-12 DOI: 10.1016/j.jdeveco.2025.103618

Digitalization can increase firm productivity, but in developing countries with labor market frictions, not all firms are able to capitalize on digitalization opportunities. This study uses data from India – where a demonetization policy led to a large increase in digital payments – to examine the impacts of digitalization on firms across sectors in a developing country in the short run. I find that service firms experienced growth in income and productivity while manufacturing firms witnessed a decline. I then explore the mechanisms driving this divergence. The results show that service firms invested more in information and communications technology (ICT) capital and hired more complementary skilled ICT labor, whereas manufacturing firms did not. Notably, this influx of skilled ICT workers into the service sector was drawn from the manufacturing sector due to limited spatial labor mobility. During this period, wages for ICT labor were driven up while remaining stagnant for other workers. These findings underscore how digitalization, in the presence of labor market constraints, can exacerbate short-term sectoral divergence in productivity growth and shed light on its impacts on the growth trajectories of developing countries.
数字化可以提高企业生产率,但在存在劳动力市场摩擦的发展中国家,并非所有企业都能够利用数字化机会。本研究使用来自印度的数据——印度的废钞政策导致了数字支付的大幅增长——来研究数字化在短期内对发展中国家各行业企业的影响。我发现,服务企业的收入和生产率都在增长,而制造业企业的收入和生产率却在下降。然后,我将探讨导致这种分歧的机制。结果表明,服务业企业对信息通信技术(ICT)资本的投入和雇佣互补性较强的熟练ICT劳动力,而制造业企业则不然。值得注意的是,由于劳动力空间流动性有限,流入服务部门的熟练信通技术工人来自制造业。在此期间,信息通信技术劳动力的工资上涨,而其他工人的工资却停滞不前。这些发现强调了在劳动力市场存在约束的情况下,数字化如何加剧生产率增长的短期部门差异,并揭示了其对发展中国家增长轨迹的影响。

A growing body of literature indicates that heat stress and precipitation deficiencies can pose a critical threat to human health, particularly in less developed countries with low coping capacities and high exposure. The aims of this study are twofold. First, we shed light on the recall of drought events in rural Thailand by linking longitudinal survey data with objective meteorological data. Here, an anomaly in the survey design serves as a natural experiment. We find that a shorter time interval between surveys has a large positive effect on households correctly reporting a drought event. Second, we examine the health effects of droughts comparing two drought measures. In our panel over seven waves, we find a strong effect on diseases, which is slightly stronger for the objective measure than when using the reported drought measure.
越来越多的文献表明,热应激和降水不足可能对人类健康构成严重威胁,特别是在应对能力低、暴露程度高的欠发达国家。这项研究的目的是双重的。首先,我们通过将纵向调查数据与客观气象数据联系起来,阐明了对泰国农村干旱事件的回忆。在这里,调查设计中的异常可以作为自然实验。我们发现,较短的调查时间间隔对正确报告干旱事件的家庭有很大的积极影响。其次,我们通过比较两种干旱措施来检验干旱对健康的影响。在我们的七波小组中,我们发现了对疾病的强烈影响,这种影响在客观测量中比使用报告的干旱测量时略强。
