    Parallel Title: Erscheint auch als Print Version: Carletto, Calogero Agricultural Data Collection to Minimize Measurement Error and Maximize Coverage
    Keywords: Agricultural Knowledge and Information Systems ; Agricultural Research ; Agricultural Sector Economics ; Agriculture ; Data Collection ; Survey Design
    Abstract: Advances in agricultural data production provide ever-increasing opportunities for pushing the research frontier in agricultural economics and designing better agricultural policy. As new technologies present opportunities to create new and integrated data sources, researchers face trade-offs in survey design that may reduce measurement error or increase coverage. This paper first reviews the econometric and survey methodology literatures that focus on the sources of measurement error and coverage bias in agricultural data collection. Second, it provides examples of how agricultural data structure affects testable empirical models. Finally, it reviews the challenges and opportunities offered by technological innovation to meet old and new data demands and address key empirical questions, focusing on the scalable data innovations of greatest potential impact for empirical methods and research

    Parallel Title: Erscheint auch als Print Version: Carletto, Calogero Migration, Economic Crisis and Child Growth in Rural Guatemala: Insights from the Great Recession
    Keywords: 2008 Great Recession ; Child Growth ; Early Child and Children's Health ; Economic Shock ; Health, Nutrition and Population ; Migration ; Poverty Reduction ; Remittances ; Stunting
    Abstract: Migration has been demonstrated by various studies to be closely linked to improvements in individual- and household-level outcomes. Rather than examining the effects of migration, this paper explores whether an economic shock in United States negatively affected migrant households in rural Guatemala. Treating the Great Recession as a natural experiment affecting migrant and non-migrant households differently, the paper puts the spotlight on the effect on child anthropometry, including longer-term indicators of height-for-age z-scores. Panel data on children and multiple children in households enable double- and triple-difference estimation. In relative terms, migrant households fared far worse than non-migrant households over the period. In particular, large advantages in child anthropometric status for the youngest children in migrant households in 2008, just prior to the crisis, were substantially diminished four years later. The findings underscore the possible fragility of the benefits of migration, particularly in the face of a substantial economic shock, and point to the potential importance of deepening social safety nets
