We present a model of imperfect price competition where not all firms can sell to all consumers. A network structure … network, which corresponds to perfect competition, and decreases monotonically as the network becomes less connected until … competition when consumerscan either buy from a single firm or from all firms. -- Network markets ; price competition ; oligopoly …

When workers send applications to vacancies they create a network. Frictions arise if workers do not know where other … workers apply to (this affects network creation) and firms do not know which candidates other firms consider (this affects … network clearing). We show that those frictions and the wage mechanism are in general not independent. Equilibria that exhibit …
