Import Restrictions in the Presence of a Health Risk : An Illustration Using Fmd

We present a simple model linking infection risk from imports to a tariff. The risk causes the exporter of the infected product to face a higher tariff than would otherwise be the case. A numerical example is developed for U.S. beef imports from nations with Foot‐and‐Mouth Disease (FMD). The additional tariffs are sensitive to the specification of risk and the expected magnitude of loss due to an FMD outbreak. For a low risk of importing FMD, the tariffs levied against the exporter of FMD‐infected beef are not prohibitive but become so as the risk or expected output loss rises
