Resumen
Descripción
This article provides a structural framework for studying the market performance of various food
industries. It revisits the benefit-function approach to modeling demand and extends its application
to the empirical industrial-organization literature. We illustrate the empirical value of our model
in an econometric analysis of competitive conditions in the retail market for branded yogurt.
The results show that retailers are engaged in imperfect competition. Furthermore, national brand
yogurt remains an important tool for retail profitability.
