Ground beef is an important component of overall beef demand. We utilize retail scanner data of branded ground beef with differing lean percentage levels to provide information on appropriate aggregation schemes and determine whether these schemes are consistent with weakly separable preferences. This study provides the first estimated price and income elasticities for individual ground beef lean percentage and branded products. These estimates provide better understanding of how consumers make decisions concerning ground beef purchases.
