Why do some people become entrepreneurs while others stay in paid employment? Searching for a distinctive set of entrepreneurial skills that matches the profile of the entrepreneurial task, Lazear (2005) introduced a theoretical model featuring skill variety for entrepreneurs. He argues that because entrepreneurs perform many different tasks, they should be multi-skilled in various areas. We investigate whether a variety of early interests and activities in adolescence predicts subsequent variety in skills and knowledge. We also investigate determinants of skill variety and variety of early interests and activities.
