Supply and demand models are an important part of economic theory and these models underlie much of the applied work done by economists. To answer questions about the effects of specific shocks to a sector, economists need estimates of the relevant supply and demand elasticities. To support the applied analysis of the Animal Products Branch, this bibliography of recent empirical estimates of U.S. demand and supply elasticities for livestock, meat, and poultry was compiled. Each reference is followed by a brief discussion of the techniques and data used and (usually) tables showing the estimated elasticities.
