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.","PeriodicalId":55537,"journal":{"name":"American Journal of Agricultural Economics","volume":"107 4","pages":"1117-1151"},"PeriodicalIF":4.2,"publicationDate":"2025-04-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144524604","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.","PeriodicalId":55537,"journal":{"name":"American Journal of Agricultural Economics","volume":"107 5","pages":"1261-1289"},"PeriodicalIF":3.3,"publicationDate":"2025-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/ajae.12536","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145022350","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.","PeriodicalId":55537,"journal":{"name":"American Journal of Agricultural Economics","volume":"107 4","pages":"993-1015"},"PeriodicalIF":4.2,"publicationDate":"2025-03-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144524629","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Because nationally representative food-consumption data are absent during this time, we use several data sources to predict changes in diet quality. We first estimate a model of diet quality as a function of food source acquisitions using prepandemic food-consumption surveys. These estimates are applied to observed changes in monthly acquisitions across five food sources: grocery, fast food, restaurant, school, and other sources. Although we predict the average school-aged child experienced a loss in daily diet quality by 2%–3% on a typical school day, results are largely driven by those receiving free or reduced-price school meals. Specifically, students in the full-price category maintained comparable diet quality from March 2020 to July 2022, deviating no more than 1% from prepandemic levels. Students typically receiving free/reduced-price meals, however, had lower-quality diets by at least 3% during each school month, upwards of 5.5%. The lower bound prediction is driven by the reduced consumption of school meals, whereas the upper bound is driven by the degree to which schools opted to relax the nutritional standards for school meals due to COVID-19 federal waivers. Results highlight the important effects of school meal programs on diet quality, especially for children from lower-income households.","PeriodicalId":55537,"journal":{"name":"American Journal of Agricultural Economics","volume":"108 1","pages":"363-382"},"PeriodicalIF":3.3,"publicationDate":"2025-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/ajae.12542","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145706473","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is clear that poverty contributes to food insecurity, but extant research focuses almost exclusively on income poverty (IP). We move beyond income-centric conceptions of poverty to propose that net worth poverty (NWP) is an important, but overlooked, measure of marginalization and financial hardship that puts families at risk of food insecurity. A family is NWP if they have insufficient net worth to meet basic needs for 3 months, and NWP has increased in recent decades even while IP declined. This paper explores how NWP and its two subcomponents—asset and debt poverty—relate to food insecurity using data from the 2015–2021 Panel Study of Income Dynamics on 5762 households with at least one resident child under 18. Net worth poor households were 11.3% more likely than households that were neither net worth nor income poor to be food insecure. Although asset poverty and debt poverty were associated with increased risks, asset poverty more than doubled the risk of food insecurity relative to debt poverty. Black and Hispanic child households were more likely to be NWP and food insecure than White households, but associations between poverty and food insecurity did not vary by racial and ethnic subgroup. Findings demonstrate how low wealth, including financial assets and debts, affect risks of food insecurity.","PeriodicalId":55537,"journal":{"name":"American Journal of Agricultural Economics","volume":"107 4","pages":"1016-1040"},"PeriodicalIF":4.2,"publicationDate":"2025-03-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144524549","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
