We investigate the interface between trade and damages from invasive species (IS), focusing on escalation in tariffs between raw-input and processed-good markets, and its implication for IS-based damages. The current tariff escalation in processed agro-forestry products motivates our analysis. Tariff escalation exacerbates the likelihood of IS introduction by biasing trade flows towards increased trade of primary commodity flows and against processed-product trade. We show that a reduction of tariff escalation, by lowering the tariff on processed goods increases allocative efficiency and reduces IS-based damages, 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.
