Tariff Escalation and Invasive Species Risk

By Anh Thuy Tu and John C. Beghin

Abstract

We investigate the interface between trade and invasive species (IS) risk, focusing on the existing tariff escalation in agricultural and food-processing markets and its implication IS risk. Tariff escalation in processed agro-forestry products exacerbates the risk of IS by biasing trade flows towards increased trade of primary commodity flows and against processed-product trade. We show that reductions of tariff escalation by reduction of the tariff on processed goods increase allocative efficiency and reduce the IS externality, a win-win situation. We also identify policy menus for trade reforms involving tariffs on both raw input and processed goods leading to win-win situations.International Relations/Trade,
