“Upgrade or Migrate: the Effects of Fertilizer Subsidies on Rural Productivity and Migration”
[paper | twitter thread | mastodon thread]

abstract

Rural development programs often emphasize investments in agriculture, but farmers may instead prefer to divest and leave. I explore how input subsidy programs allow adjustments across two margins: agricultural upgrades and out-migration. Using a large-scale Zambian program and a difference-in-differences design, I find that subsidies increased both fertilizer adoption (upgrades, +79%) and out-migration (+12%). Out-migration rose, funded by farmers re-selling subsidized inputs in the short term (+11%) and using income from productivity gains in the medium term (+14%). Estimates from a choice model show that resales efficiently reallocate fertilizer, and that the ISP achieved higher agricultural upgrades than revenue-neutral cash-transfers.
