Term Structure of Equity and Bond Yields over Business Cycles

Abstract

Recent findings on the term structure of equity and bond yields pose serious challenges to existing equilibrium asset pricing models. This paper presents a new equilibrium model of subjective expectations to explain the joint historical dynamics of equity and bond yields (and their yield spreads). Equity/bond yields movements are mainly driven by subjective dividend/GDP growth expectations. Yields on short-term dividend claims are more volatile because short-term dividend growth expectation mean-reverts to its less volatile long-run counterpart. Procyclical slope of equity yields is due to the counter-cyclical slope of dividend growth expectations. The correlation between equity returns/yields and nominal bond returns/yields switched from positive to negative after the late 1990s, mainly owing to a stronger correlation between real GDP growth and real dividend growth expectations, and only partially due to procyclical inflation. Dividend strip returns are predictable and the strength of predictability decreases with maturity due to predictable dividend forecast errors and revisions. The model is also consistent with the data in generating persistent and volatile price-dividend ratios, and excess return volatility.
