Internal and external labour mobility in Canada

Abstract

Quasi-longitudinal Canadian microdata was used to compare the movement of individuals between employers with job changes taking place within firms. Internal mobility is found to be much less common than job changing between firms. Workers changing jobs within a firm are more likely to be older and have higher wages and longer tenures in the jobs they leave than individuals employers. This provides some support for the job-matching hypothesis underlying recent research on the causes of individual mobility, although it is also clear that workers in large or unionized firms are more likely to have the opportunity for internal promotion. While wage gains obtained through internal mobility are smaller than those achieved through external mobility, wage levels are higher for individuals moving within the firm. It is argued that this observation is consistent with a dual labour markets interpretation of mobility patterns.
