Many financial advisors and much of the academic literature often argue that young people should place most of their savings in stocks. In contrast, a significant fraction of U.S. households do not hold stocks. Moreover, life-cycle stock holdings are 'hump shaped:' Young investors typically hold very little in stocks, progressively increase their holdings as they age, and decrease their exposure to stock market risk when they approach retirement. In this article, we show how long-run labor income risk helps explain this evidence. Next, we discuss recent developments in the literature that has studied the effect of long-run labor income risk on the valuation of pension fund obligations, their funding, and the allocation of pension assets across different investment classes.
