The Expat-preneur: A real deal?

Over the last week, I read a couple of academic papers about expatriation. Many papers are dealing with the effect of expatriation on the relationship and the influence of the Expat Partner on the success of the assignment.
One paper, in particular, caught my attention: „The expat-preneur: conceptualizing a growing international career phenomenon“ by M. Vance, Y. McNulty, Y. Paik and J. D’Mello.
