Professor Francis Greene looks at how self-employed men have higher levels of testosterone

Professor Francis Greene is undertaking a study that is looking at how abundance of the sex hormone testosterone is associated with being self-employed.

Alongside colleagues from the University of Surrey and the University of Adelaide, the researchers found that in a study of Australian men, those individuals with higher testosterone levels were more likely to be self-employed than either employed or not working. Professor Greene said:

Because men's testosterone levels have been associated with risk-taking and competitive behaviours in past studies, our study sought to examine if there was also a relationship between testosterone levels and self-employment.

The study assessed 1,199 adult Australian males aged between 35 and 80 years-old. The paper, Testosterone is associated with self-employment among Australian men, is published in the March edition of Economics and Human Biology.
