Abstract We present a theory in which the interaction between limited sharing of idiosyncratic labor income risk and labor adjustment costs (that endogenously arise through search frictions) determines interest rate dynamics. In the general equilibrium, the interaction of these two ingredients relates bond risk premiums, cross-sectional skewness of income growth, and labor market tightness. Our model rationalizes an upward-sloping average yield curve and predicts a negative relation between labor market tightness and bond risk premiums. We provide evidence for our theory’s mechanism and predictions.

Abstract We show that time-varying risk premium in financial markets can explain a key, yet puzzling, feature of labor markets: the large differences in unemployment risk across worker age groups over the business cycle. Our search model features a time-varying risk premium and learning about unobserved heterogeneity in worker productivity. Their interaction generates large real effects through firms’ labor policies. Our model predicts higher unemployment risk of younger workers relative to prime-age workers when risk premium is high, and the employment ratio of prime-age to young workers to be more cyclical in high beta industries. We find empirical support for these predictions. Authors have furnished an Internet Appendix, which is available on the Oxford University Press Web site next to the link to the final published paper online.

We document several facts about corporate debt maturity: (1) debt maturity is pro-cyclical, (2) higher-beta firms tend to have longer maturity, and (3) shorter maturity amplifies the sensitivity of credit spreads to aggregate shocks. We present a dynamic capital structure model that explains these facts. In the model, leverage and maturity choices are interdependent, which reflect the tradeoffs of liquidity discounts of long-term debt, repayment risks of short-term debt, and the benefit of short-term debt as a commitment device for timely leverage adjustments. Additionally, the model helps quantify the effects of maturity dynamics on the term structure of credit spreads.
