Leverage and the Cross‐Section of Equity Returns

Building on theoretical asset pricing literature, we examine the role of market risk and the size, book‐to‐market (BTM), and volatility anomalies in the cross‐section of unlevered equity returns. Compared with levered (stock) returns, unlevered market beta plays a more important role in explaining the cross‐section of unlevered equity returns, even after controlling for size and BTM. The size effect is weakened, while the value premium and the volatility puzzle virtually disappear for unlevered returns. We show that leverage induces heteroskedasticity in returns. Unlevering returns removes this pattern, which is otherwise difficult to address by controlling for leverage in regressions.     

DETERMINANTS OF THE SAVING RATE: AN INTERNATIONAL COMPARISON

Economists have extensively analyzed the interactions between economic-demographic factors and saving. Fertility rates and the dependency ratio have received considerable attention, but the effect of life expectancy improvements have not been analyzed explicitly. This paper provides an added dimension to the existing literature by empirically examining the role of life expectancy as a determinant of saving. Recent data demonstrate that life expectancy is a statistically significant and quantitatively important factor affecting less developed countries' saving performance. One must consider human capital investments when assessing population growth's impact on saving. The analysis here is one of few that incorporate human capital in defining saving. The overall results are sensitive to level of development and regional diversity .
