This paper describes a search model with a continuum of worker and job types, transferable utility and an increasing returns to scale contact technology. We apply a second order Taylor expansion to characterize the equilibrium. One third of the increasing returns in contacts are absorbed by...

We characterize the equilibrium of a search model with a continuum of job and worker types, wage bargaining, free entry of vacancies and on-the-job search. The decentralized economy with monopsonistic wage setting yields too many vacancies and hence too low unemployment compared to first best....
