Prior theory suggests that time variation in the degree to which leverage constraints bind affects the pricing kernel. We propose a measure for this leverage constraint tightness by inverting the argument that constrained investors tilt their portfolios to riskier assets. We show that the...

We develop a new method to estimate Tobin's qs of conglomerate divisions without relying on standalone firms. Divisional qs differ considerably from qs of standalone firms and, consistent with theories of corporate diversification, are less volatile and less sensitive to macroeconomic shocks. In...

Firms with high levels of organization capital, a firm-specific production factor provided by key employees, are known to be risky and earn high stock returns. We argue that fragility of organization capital -- its sensitivity to potential disruptions -- is an independently important determinant...

The Fama-French factors are ubiquitous in empirical finance, industry, and law. We find that factor returns differ substantially depending on when the data were downloaded. The effects of these retroactive changes are large. Holding the sample period constant and varying only factor vintages, we...
