Demand and equilibrium with inferior and Giffen behaviors

Le Van, Cuong and Pham, Ngoc-Sang (2019): Demand and equilibrium with inferior and Giffen behaviors.

Abstract

We introduce a class of differentiable, strictly increasing, concave utility functions exhibiting an explicit demand of a good which may have Giffen behavior. We provide a necessary and sufficient condition (bases on prices and consumers’ preferences and income) under which this good is normal, inferior or Giffen.
