Entry Decision and Pricing Policies

We extend the analysis of the impact of firms' pricing policies upon entry to a framework where price competition and differentiated products are present. We consider a model where an incumbent serves two distinct and independent geographical markets and an entrant may enter in one of the markets. Entry under discriminatory pricing is more likely than under uniform pricing when entry is profitable under discriminatory pricing but unprofitable under uniform pricing. Our results show entry under discriminatory pricing may be more, less or equally likely than under uniform pricing. We show that the degree of product substitutability affects the impact of pricing policies upon entry decision.
