Efficiency and Redistribution in Environmental Policy: An Equilibrium Analysis of Agricultural Supply Chains

Autor: Tomas Domínguez-Iino

Abstract: I build an empirical model of the South American agricultural sector to show how environ mental policy is transmitted along a supply chain when regulation at the externality’s source is infeasible. Given obstacles to a carbon tax on farmers, I show how alternative market-based policies—downstream agribusiness taxes—reduce upstream emissions but their effectiveness is limited by international leakage and domestic mistargeting, while also being regressive. Agribusiness monopsony power worsens targeting by lowering pass-through to upstream farmers in uncompetitive and emissions-intense regions, thus eroding the Pigouvian signal where social cost is highest. By contrast, command-and-control tools perform robustly when markets face pre-existing distortions.
