Sustainability of collusion with imperfect price discrimination and inelastic demand functions

Abstract

We study the impact of product differentiation on collusion sustainability in the case of imperfect price discrimination and inelastic demand functions. We show that differentiation facilitates the sustainability of collusion. Therefore, the indifference result of Gupta and Venkatu (2002) does not hold when imperfect price discrimination is introduced.
