In the paper we test a homogenous agent version of the Montgomery's (1991) non-cooperative wage posting model. The inclusion of intrinsic costs, related to the uncertainty when changing the alternative agents are already using, alters the outcome of the model in two respects: firstly, it...

This paper explains why firms with identical opportunities may use different technologies and offer different wages. Our key assumption is that workers must engage in costly search in order to gather information about jobs (Stigler, 1961). In equilibrium, some firms adopt high fixed cost, high...
