All About Balance? A Test of the Jack-of-all-Trades Theory Using Military Enlistment Data
According to the Jack-of-all-trades theory, people with a balanced set of skills are more suitable for self-employment than are those without. In this paper we test this theory using Swedish Military Enlistment data. […] We find clear support for the Jack-of-all-trades theory, in the sense that the likelihood of being self-employed is higher for individuals whose skills are balanced. In addition, their earnings from self-employment tend to be higher.
