Financial assets such as stocks and bonds ar only one component of an investor's total economic worth. Other assets, such as human capital, real estate, and pensions often represent a significant portion of an investor's total wealth.

This paper provides evidence that industry-specific human capital, region-specific housing wealth, and pensions have statistically significant exposures to different asset classes and risk factors.

Gamma will vary for different types of investors and for different strategies; however in this paper we focus on five fundamental financial planning decisions/techniques: a total wealth framework to determine the optimal asset allocation, a dynamic withdrawal strategy, incorporating guaranteed income products (i.e., annuities), tax-efficient decisions, and liability-relative asset allocation optimization.
