Investing Over the Life Cycle with Long-Run Labor Income Risk

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. Investors typically hold very little in stocks when they are young, progressively increase their holdings as they age, and decrease their exposure to stock market risk when they approach retirement. The authors show how long-run labor income risk helps explain this evidence. Moreover, they discuss the effect of long-run labor income risk on the valuation of pension plan obligations, their funding, and the allocation of pension assets across different investment classes.

Conflict of Interest or Certification? Evidence from IPOs Underwritten by the Firm's Relationship Bank

We examine the long-term return performance and fundamental valuation of IPOs underwritten by relationship banks. We find that over one- to three-year horizons these IPOs yield returns similar to those on IPOs underwritten by non-relationship banks. Moreover, we show that there is selection among firms that go public with their relationship bank. Investors value these new issues higher than similar IPOs underwritten by non-relationship banks. These findings support the certification role of relationship banks and suggest that, in this respect, the effect of the 1999 repeal of Sections 20 and 32 of the Glass-Steagall Act has not been negative.

Human Capital and Long-Run Labor Income Risk

This review article examines the role of labor income risk in determining the value of a person’s human capital. We draw on the existing literature to present a model that incorporates various types of shocks to earnings. Within this framework, we highlight the implications of different assumptions about the correlation between market returns and labor income growth for the value of human capital and its riskiness. Further, the article surveys other work that applies similar ideas to assess the value and risk of pension promises. Finally, we discuss how to enrich the environment with heterogeneity in preferences and stock market exposures; endogenous labor supply and retirement decisions; health shocks; and human capital investment.

The Interplay between Financial Conditions and Monetary Policy Shocks

We study the interplay between monetary policy and financial conditions shocks. Such shocks have a significant and similar impact on the real economy, though with different degrees of persistence. The systematic fed funds rate response to a financial shock contributes to bringing the economy back towards trend, but a zero lower bound on policy rates can prevent this from happening, with a significant cost in terms of output and investment. In a retrospective analysis of the U.S. economy over the past 20 years, we decompose the realization of economic variables into the contributions of financial, monetary policy, and other shocks.
