2. What predicts good work performance?
Personality (e.g., Rauch & Frese, 2007; Zhao &
Seibert, 2006)?
Competencies (e.g. Markman, 2007)?
Selfish passion for work (e.g., Shane, Locke &
Collins, 2003)?

13. Measurement equivalence may be an issue when
comparing sub-cultures
The self employed have more work engagement
and work more excessively, but not more
compulsively than salaried employees
Working compulsively suppressed the positive
effect of working excessively
This pattern more visible among the self-
emloyed,
This effect stronger for innovation and extra role
behavior
