Yes, most likely. The firm-level evidence on costly reversibility is even stronger than the prior evidence at the plant level. The firm-level investment rate distribution is highly skewed to the right, with a small fraction of negative investments, 5.79%, a tiny fraction of inactive investments,...

A detailed treatment of aggregation and capital heterogeneity substantially improves the performance of the investment CAPM. Firm-level predicted returns are constructed from firm-level accounting variables and aggregated to the portfolio level to match with portfolio-level stock returns....

Many recently proposed, seemingly different factor models are closely related. In spanning tests, the q-factor model largely subsumes the Fama-French (2015, 2018) 5-and 6-factor models, and the q5-model captures the Stambaugh-Yuan (2017) model. The Stambaugh-Yuan factors are sensitive to their...

A deep-ingrained doctrine in asset pricing says that if an empirical characteristic-return relation is consistent with investor “rationality,” the relation must be “explained” by a risk (factor) model. The investment approach questions the doctrine. Factors formed on characteristics are...

We derive and test q-theory implications for cross-sectional stock returns. Under constant returns to scale, stock returns equal levered investment returns, which are tied directly to firm characteristics. When we use GMM to match average levered investment returns to average observed stock...

Integrating national accounting with financial accounting, we provide firm-specific estimates of current-cost capital stocks for the entire Compustat universe, as well as an array of estimates of investment flows, economic depreciation rates, and capital and investment price deflators. The...
