Coupons and oligopolistic price discrimination

Article Abstract:

Sales promotion through coupons in a duopolistic market is analyzed. Coupons enable sellers to segregate market segments with varying degrees of consumer brand loyalty. Price discrimination in this form is profitable for individual sellers when costs of couponing is low enough. However, couponing increases competition and lessens profits at equilibrium levels. Consumer surplus is reduced when the cost of couponing increases.
