The document discusses the need for improved economic analysis of the impacts of animal diseases in developing countries, particularly analyses that consider poverty impacts and incorporate a bottom-up approach. It outlines how value chain analysis can provide a framework for understanding the interactions between diverse actors and how this impacts disease transmission and control. The document calls for new modeling approaches and data resources that integrate epidemiology and economics from a systems perspective and better reflect the behavioral constraints and incentives of actors throughout the value chain.
