Abstract

We derive a (quadratic) inverse demand system (IQUAIDS), that generalizes the (almost ideal) inverse demand system. We discuss how the assumptions of separability and concavity can be simultaneously accommodated within the model, thus giving a (locally) separable and concave quadratic demand system. An empirical application is provided for illustrative purposes.
