title: Selling Crops Early to Pay for School: A Large-scale Natural Experiment in Malawi

description: &lt;p&gt;PI-Provided Abstract: In 2010, primary school in Malawi began in September, three months earlier than in 2009. We show that this change forced households to sell crops early, when prices are low. The effect is limited to households with school children, increases in the number of children, and is present only for poor households. Households that financed school by selling crops early missed out on an expected 17.3-26.5% increase in output prices over three months. There is little evidence of improved schooling outcomes as a result of the change. We discuss the implications for policies that offer farmers commitment opportunities at harvest.&lt;/p&gt;

title: The Role of Nonfarm Influences in Ricardian Estimates of Climate Change Impacts on U.S. Agriculture

description: &lt;p&gt;PI-provided Abstract: The Ricardian approach is a popular hedonic method for analyzing climate change impacts on agriculture. The approach typically relies on a cross-sectional regression of farmland asset prices on fixed climate variables, making it particularly vulnerable to omitted variables. I conduct a long-spanning Ricardian analysis of farmland prices in the eastern US (1950-2012) and find a convergence of evidence indicating that large and precisely-estimated climate change damages for recent cross-sections (&gt;1970s), also found in the literature, can be explained by omitted factors extraneous to the agricultural sector. I propose and evaluate a simple strategy to circumvent such nonfarm biases in the form of a Ricardian model based on cash rents (2009-2016). The new damage estimates on non-irrigated cropland and pasture rents cannot be statistically distinguished from zero but point to a cautionary long-term outlook for US agriculture under extreme climate change scenarios. The findings are robust to multiple checks and alternative explanations.&lt;/p&gt;

title: Reproduction Materials for: A randomized trial of iron- and zinc-biofortified pearl millet-based complementary feeding in children aged 12 to 18 months living in urban slums

description: &lt;p&gt;Background &amp; aimsBiofortification of staple crops with higher levels of micronutrients via traditional breeding methods is a sustainable strategy and can possibly complement fortification and other interventions to target micronutrient deficiencies in low resource settings, particularly among vulnerable populations such as children. We aimed to determine if iron- and zinc-biofortified pearl millet (FeZnPM, Dhanashakti, ICTP-8203Fe)-based complementary feeding improves nutritional status, including iron biomarkers and growth, in children living in urban slums of Mumbai.MethodsWe conducted a randomized controlled trial of FeZnPM among 223 children aged 12–18 months who were not severely anemic at baseline (hemoglobin ≥9.0 g/dL). Children were randomized to receive either FeZnPM or conventional non-biofortified pearl millet (CPM) daily for 9 months. Iron status (hemoglobin, serum ferritin), and anthropometric indicators (length, weight, mid-upper arm circumferences, triceps and subscapular skinfolds) were evaluated at enrollment and throughout the trial. World Health Organization (WHO) anthropometric Z-scores were calculated using WHO growth standards. Primary outcomes were hemoglobin and serum ferritin concentrations, and growth, defined as WHO Z-scores. An intent to treat approach was used for analyses. We used the Hodges–Lehmann–Sen test to assess the change in primary outcomes between baseline and the last visit and report corresponding 95% confidence intervals.ResultsAt baseline, 67.7% of children were anemic (hemoglobin &lt;11 g/dL) and 59.6% were iron deficient (serum ferritin &lt;12 μg/L). FeZnPM did not significantly increase iron biomarkers or improve growth, compared to CPM. In subgroup analyses, FeZnPM improved hemoglobin concentrations in male children, and in children with iron deficiency or iron depletion (serum ferritin &lt;25.0 μg/L) at baseline, relative to CPM.ConclusionsDaily consumption of FeZnPM-based complementary foods did not significantly impact iron and zinc status or growth in children living in Mumbai's urban slums. However, the intervention significantly improved hemoglobin concentrations among male children and among individuals who were iron-deficient or iron-depleted at baseline.&lt;/p&gt;

title: Replication files for: Nutrition and the Gut Microbiota in 10–18-Month Old Children Living in Urban Slums of Mumbai, India

description: &lt;p&gt;&lt;strong&gt;PI-Provided Abstract&lt;/strong&gt;: In this cross-sectional study, we describe the composition and diversity of the gut microbiota among undernourished children living in urban slums of Mumbai, and determine how nutritional status, including anthropometric measurements, dietary intakes from complementary foods, feeding practices, and micronutrient concentrations, are associated with their gut microbiota, for the first time. We collected rectal swabs from children aged 10–18 months living in urban slums of Mumbai participating in a randomized controlled feeding trial and conducted 16S rRNA sequencing to determine the composition of the gut microbiota. Across the study cohort, Proteobacteria dominated the gut microbiota at over 80% relative abundance, with Actinobacteria representation at &lt;4%, suggesting immaturity of the gut. Increased microbial ɑ diversity was associated with current breastfeeding, greater head circumference, higher fat intake, and lower hemoglobin concentration and weight-for-length Z-score. In redundancy analyses, 47% of the variation in Faith’s PD could be accounted for by age, and iron and polyunsaturated fatty acid intakes. Differences in community structure (β-diversity) of the microbiota were observed among those consuming fats and oils the previous day compared to those consuming none. Our findings suggest that growth, diet, and feeding practices are associated with gut microbiota metrics in undernourished children, whose gut microbiota were comprised mainly of Proteobacteria, a phylum containing many potentially pathogenic taxa.Keywords: infant, child, growth, diet, nutrition, feeding practices, microbiome, fat intake, anthropometry&lt;/p&gt;

title: HIFLD OPEN US Coal Fields 1

description: This dataset is a polygon shapefile representing the most recent update of the coal fields of the conterminous United States. Scale of data is 1:5,000,000. This publication is based on a USGS paper map that was a representation of the coal fields and major regions of the time (Trumbull, 1960). Trumbull's 1960 map was digitized and coal fields from the Gulf Coast were added to create USGS OFR 96-92, Coal Fields of the Conterminous United States (Tully, 1996). Tully's (1996) publication consisted of a map in pdf format that could be printed, and an ArcInfo coverage of the coal fields, attributed with rank and potential economic use (minability) of the coal. This new dataset includes a pdf showing updated coal fields and a shapefile that contains attributes on coal rank (without regard to outdated economic standards), province, name, and age. The data used to update Tully's (1996) digital map was collected from the National Coal Resource Assessment (NCRA) regional Professional Papers produced by the USGS and from AAPG Discovery Series 14/Studies in Geology 62, all of which were conducted by USGS geologists and professional staff. A small number of field names were added and or updated in the western states of Washington, Oregon, California, Utah, Colorado and New Mexico using additional coal resource literature.The full study is available from USGS: https://doi.org/10.3133/ofr20121205<br>

title: Reproducibility Package for: Managing a policy paradox? Responses to textual warning labels on e-cigarette advertisements among US national samples of youth overall and adults who smoke and/or vape

description: &lt;p&gt;&lt;strong&gt;PI-Provided Abstract&lt;/strong&gt;: We conducted a web-based survey experiment to test the impact of five e-cigarette warning labels on youth and adult e-cigarette risk beliefs, willingness to use e-cigarettes, and (among people who smoke or vape) considerations to quit these products. The five warnings appeared on e-cigarette advertisements and featured either the current FDA warning about nicotine, a youth-targeted warning about the risks of vaping on youth cognitive development, chemical constituents of vaping products, chemical constituents + specific associated harms, or constituents + harms + equivalence with combustible cigarettes. We contracted with NORC to collect data resulting in final samples of 1639 adults (ages 18+) who smoke, vape, or use both products, from NORC’s probability-sampled AmeriSpeak Panel and 1217 youth (ages 14–17) from NORC’s AmeriSpeak Teen Panel and Lucid's non-probability opt-in panel. Provided here are the complete datasets, which include data on additional outcomes, along with complete study materials and syntax to replicate the findings we report in Niederdeppe et al. (2023).&lt;/p&gt;

title: Antecedents and Near-Term Consequences for Interdisciplinary Dissertators

description: &lt;p&gt;PI-Provided Abstract: Given the complexity of questions studied by academicians, institutions are increasingly encouraging interdisciplinary research to tackle these problems; however, neither the individual-level pathways leading to the pursuit of interdisciplinary research nor the resulting market outcomes have been closely examined. In this study, we focus attention on the individuals who complete interdisciplinary dissertations to ask “who are they and how do they fare after earning the PhD?” Since interdisciplinary research is known to be relatively risky among academics, we examine demographic variables that are known to be associated in other contexts with risk-taking before considering whether interdisciplinarians’ outcomes are different upon graduating. First among our three main findings, students whose fathers earned a college degree demonstrated a 1.2% higher probability of pursuing interdisciplinary research. Second, the probability that non-citizens pursue interdisciplinary dissertation work is 4.7% higher when compared with US citizens. Third, individuals who complete an interdisciplinary dissertation tend to earn approximately 2% less in the year after graduation; however, mediation analyses show that the decision to become a postdoctoral researcher accounts for the apparent salary penalty. Our findings shed light on the antecedents and near-term consequences for individuals who complete interdisciplinary dissertations and contribute to broader policy debates concerning supports for academic career paths.

title: Reproduction Materials for: The Role of Education Interventions in Improving Economic Rationality

description: &lt;p&gt;PI-Provided Abstract: Schooling rewards people with labor market returns and non-pecuniary benefits in other realms of life. However, there is no experimental evidence showing that education interventions improve individual economic rationality. We examine this hypothesis by exploiting a randomized one-year financial support program for education in Malawi that reduced absence and dropout rates, and increased scores on a qualification exam of female secondary school students. We measured economic rationality four years after the intervention using lab-in-the-field experiments to create scores of consistency with utility maximization that are derived from revealed preference theory. We find that those treated had higher scores of economic rationality. The results remain robust after controlling for changes in cognitive and non-cognitive skills. Our results suggest that education enhances the quality of economic decision-making. This study was pre-registered as: S. Choi, B. Kim, H. B. Kim, C.

title: Reproducibility Package for: Sources of Family Income Across Childhood in Families with Nonresident Fathers

description: &lt;p&gt;Unpartnered mothers rely upon a variety of formal and informal sources of income to support their coresident minor children. We build upon work that has focused on selective populations and shorter time horizons to describe the family income sources that U.S. women and their minor children rely upon over up to 17 years following an unpartnered birth or union dissolution (Panel Study of Income Dynamics 2001-2017, N=12,369 person-year records from 3,164 children). Using rich description and fixed-effect models, we treat family income as dynamic, mapping change in the share and amount of family income from multiple sources as children age and women gain employment experience, enter new unions, move into or out of eligibility for public support programs, and receive contributions from kin, friends, and other household members. A patchwork of income sources is the norm throughout childhood, with mothers’ earnings nearly universal but insufficient as a sole source of family income. Maternal repartnering increases family income through new partner earnings, but with offsetting reductions in other income sources, particularly from outside the household. In the context of weak institutional support for U.S. families, families with nonresident fathers rely on a complex mix of income sources to make ends meet.Keywords: family income; income transfers; father nonresidence; unpartnered parenthood&lt;/p&gt;

title: Effects of 30% and 50% Cigarette Pack Graphic Warning Labels on Visual Attention, Negative Affect, Quit Intentions, and Smoking Susceptibility among Disadvantaged Populations in the United States

description: &lt;p&gt;Abstract from Reference Pubication (see publications tab for citation): Introduction: Though the WHO Framework Convention for Tobacco Control (FCTC) calls for the implementation of large graphic warning labels (GWLs) on cigarette boxes, the courts have blocked the implementation of 50% labels in the United States. We conducted an experiment to explore whether changing the size of GWLs is associated with changes in visual attention, negative affect, risk beliefs, and behavioral intentions. Method: We recruited adult smokers (N = 238) and middle-school youth (N = 237) throughout the state of New York in May 2016. We randomly assigned participants to one of three between-subject conditions (no GWL [control], 30% GWL, 50% GWL). Results: Adult and youth participants looked at the GWLs longer when the GWL covered 50% versus 30% of the pack’s front. Increasing GWL size from 30% to 50% did not influence negative affect or risk beliefs, though both GWL sizes increased negative affect relative to the no-GWL control group. Exposure to 50% GWLs increased adult smokers’ intentions to quit compared to no-GWL, but smokers exposed to 30% GWLs did not differ from control. There were no differences between 50% GWLs, 30% GWLs, and control on youth smoking susceptibility. Conclusions: Findings provide some evidence of the benefits of a 50% versus 30% GWL covering the front of the pack for adult smokers and at-risk youth from socioeconomically disadvantaged backgrounds—though not on all outcomes. Implications: This research shows that 30% GWLs on cigarette packages increase negative affect relative to packages without front-of-package GWLs. Larger GWLs on cigarette packages (50% vs. 30%) increase visual attention to the warning and its pictorial content among low-SES smokers and at-risk youth but do not further increase negative affect. A 50% GWL increased adults’ quit intention compared to no GWL at all, but we were underpowered to detect modest differences in quit intentions between a 50% and 30% GWL. Future work should thus continue to explore the boundary conditions under which relatively larger GWLs influence cognitive, affective, and behavioral outcomes.&lt;/p&gt;
