Coupons and ‘everyday low prices’: price competition with multiple instruments

Abstract

A simple two‐stage game is examined, where firms compete in prices by chosen pricing instruments. Those considered include a simple, uniform pricing technology and a promotional pricing technology like an advertised discount coupon. Consumers are separated by types, informed and uninformed. Therefore, a motive for price competition exists for the purpose of separating the two types of consumers. It is shown that the sustainability of an asymmetric choice of pricing instrument between the two firms will prevail in a duopoly market in equilibrium. Consequently, the coexistence of two different pricing schemes is viable even when firms are otherwise symmetric. JEL Classification: L1, L13 Coupons et « bas prix tous les jours » : concurrence par les prix à l’aide de multiples instruments Ce mémoire examine un simple jeu à deux étapes dans lequel des entreprises se concurrencent par les prix à l’aide d’un instrument particulier. Les instruments considérés incluent une simple technologie de prix uniforme, et une technologie de prix de promotion sous la forme de l’annonce d’un coupon d’escompte. On divise les consommateurs en deux groupes – ceux qui sont informés et ceux qui ne le sont pas. Un des motifs pour ce genre de concurrence est de séparer les deux types de consommateurs. On montre qu’on peut soutenir un choix asymétrique d’instrument de tarification entre les deux entreprises dans un marché de duopole en équilibre. En conséquence, la coexistence de deux stratégies de prix différentes est viable quand les entreprises sont symétriques sous tous les autres rapports.
