Fields from Afar: Evidence of Heterogeneity in United States Corn Rotational Response from Remote Sensing Data

We construct estimates of own- and cross-price corn rotation elasticities using a field-level dataset that accounts for over 83% the US corn-producing area. allow rotational response to vary by estimating separate models across 115 subsamples we delineate Major Land Resource Areas (MLRAs) soil characteristics. The results show high degree heterogeneity. Across country, find is elastic in some areas near zero others. After aggregating national level, modeling without allowing heterogeneity produces short-run own-price elasticity planting around 0.50, which conforms latest literature. When heterogeneous price sensitivity, our preferred estimate 0.69. This evidence imposing uniform could seriously bias aggregate estimates.
