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 …
