dc.description.abstract | This study provides analytical results on the systematic relationship
between the elasticities obtained from item-aggregated data and those from SKU level data. It is shown that the brand level (or any aggregate level) elasticities are share-weighted averages of SKU elasticities. As SKUs in a brand are substitutes each other in general, the own brand elasticities would be smaller in magnitude than the own SKU elasticities and the crossbrand elasticities will be larger than cross-SKU elasticities. It is also found that when the SKU level demand function is given by a homogeneous logit model with the latent utility being linear in price, the price sensitivity parameter estimated from the brand level data should be the same as that from SKU level data if the brand level model fits data well and the brand prices are given by the weighted averages of SKU prices with the weights being within-brand SKU shares. | - |
