A semiflexible, Concave and Separable Quadratic Demand System

Research output: Contribution to journal › Article › peer-review

Abstract

Maintaining both separability and concavity in large demand systems allows to ensure that the model will satisfy integrability conditions while saving degrees of freedom. We provide an example of how separability and concavity can be managed in order to obtain a set of nonredundant restrictions, within a semiflexible QUAIDS specification: with proper data scaling, the imposition of these restrictions at a point does not imply more complexity than in the common AIDS model.
