The paper surveys articles examining the economic impacts of a livestock disease outbreak and focuses on modeling issues. One set of papers considers setting an import barrier when there is a livestock disease risk. They show that the level of a risk-based import barrier is sensitive to the impact of disease on economic welfare. The remaining articles focus on estimates of the economic impacts. An outbreak is modeled in a U.S. agricultural sector model and shows the importance of lost exports and consumer response to the magnitude of losses. The final paper argues for de-composition of the welfare impacts. Lessons for future research include improved links to epidemiological research, improved inclusion of trade, extension to non-agricultural sectors, and knowledge of consumer response.
