      abstract = {When elementary prices move strictly proportionately,  aggregation over a group of diverse products is valid, and  group demand responses can be decomposed into quality and  quantity responses. This study shows that when relative  elementary prices and group prices are stochastically  independent, a similar decomposition is valid. Empirical  results suggest consumers respond to changes in prices and  income mostly by altering the quality of meat products.  These findings imply that using commercial disappearance as  a proxy for food demand can be misleading for policy  analysis.
