1. The modeling method of disease dissemination that we adopted is a standard S-I-R (susceptible-infectious-removed) type model. Interested readers can refer to Miller (1979) or Rich (2004) for a complete description of the dynamic system.
2. We are not aware of any previous study that provides estimates for the export demand elasticity of U.S. beef to South Korea. Different values for this parameter were tried in the simulated scenarios; the results for inventories, prices, and welfare measures did not change significantly. For example, when −0.5 instead of −1 was used in scenario 6 of the first set, consumer surplus decreased by 0.0177 percent and producer surplus increased by 0.478 percent; when −2 was used in the same scenario, consumer surplus increased by 0.36 percent and producer surplus decreased by 0.81 percent. Different values did not change the conclusion drawn about the different scenarios.
