"Global Spatially Explicit Land Supply Elasticity Estimates for Economic Modeling" Authors: Braaksma, Matthew, Justin Johnson, Victor Nechifor and Willem-Jan Van Zeist Abstract National-level land supply elasticities mask crucial spatial heterogeneity in how land use responds to economic incentives. We develop high-resolution land supply elasticities at 300-meter global resolution, capturing variation in cropland, managed forest, and cultivated pastureland. We estimate fractional logit models relating land use fractions to market access and biophysical characteristics using a block regression approach applied to ~8.4 billion pixels. The resulting pixel-level elasticity database enables flexible aggregation to GTAP-AEZ zones, conservation regions, or gridded frameworks, replacing uniform national parameters with spatially explicit estimates capturing where conversion pressure concentrates. This extends prior continental analyses to global coverage and demonstrates computational feasibility of high-resolution econometric analysis at global scale. |
