Multiple Job Holding,Skill Diversification,and Mobility

In this article, we investigate the interrelated dynamics of dual jobholding, human capital, occupational choice, and mobility, using a panel sample (1991–2005) of UK employees from the British Household Panel Survey. The evidence suggests that individuals may be using multiple jobholding as a conduit for obtaining new skills and expertise and as a stepping‐stone to new careers, also involving self‐employment. Individuals doing a different secondary job than their primary occupation are more likely to switch to a new primary job in the next year, and a job that is different than their current primary employment. The results show that there are human capital spillover effects between primary and secondary employment.
