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.
