In this paper we highlight a specific mechanism through which social networks help in job search. We characterize the strength of a network by its likelihood of providing a job offer. Using a theoretical model we show that the wage differential in jobs found using networks versus those found...

We show that increasing the probability of obtaining a job offer through a network should raise the observed wages of workers in jobs found through formal channels relative to those in jobs found through the network. This prediction holds at all percentiles except the highest and lowest. The...

We study how professional networks are related to immigrant labour market integration. Matched employer-employee data for Sweden show that networks grow with time in the host country and that their composition changes from immigrant toward native network members. A firm-dyadic analysis of...

We analyse the effect of strong and weak ties on the individual probability of finding a job. Using the dynamic model of Calvó-Armengol and Jackson (2004), two results are put forward: (i) the individual probability of finding a job is increasing in the number of strong and weak ties; (ii) the...
