Thank you for this article Gregg!
I've been thinking about human capital in terms of being its own portfolio (of skills, knowledge, network, influence, creativity, etc). Each of these "assets" may or may not be at their optimal allocation to maximize an individual's earnings. Suppose I have great technical skills, but a poor personal network, so I am not easily able to get my marketable skills to the top bidder. I have seen myself and others invest more time and energy in areas where we are already heavily invested, thinking that a Master's or a PhD will be the key to multiplying my earnings potential, when in reality, there is another factor that may be the greater multiplier. Can portfolio theory be applied to an individual's human capital? I am working on this idea to identify measurable factors. I'd like to use the analogy in my role as a corporate trainer and business coach.
Cheers!
