ABSTRACT
This chapter deals with the study of recruitment processes in the labor market and the geographical differentiation in occupations which develops under various assumptions about them. Given continuous radially symmetric personal search fields and a uniformly distributed expectation of vacancies, it is possible to generate a spatial process of job change and the geographical differentiation in occupations which results. If author make the probability of having an acquaintance result from central place interaction, then each acquaintance field will be hierarchical, and the spread process will match the spatial structure of the central places. Of course it is only partly true that the spatial structure of shops, including their hierarchical functions, will match that of jobs.
