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...

Optimal investment of firms implies that expected stock returns are tied with the expected marginal benefit of investment divided by the marginal cost of investment. Winners have higher expected growth and expected marginal productivity (two major components of the marginal benefit of...

Q-theory predicts that investment frictions steepen the relation between expected returns and firm investment. Using financing constraints to proxy for investment frictions, we document only weak evidence that the investment-to-assets and asset growth effects in the cross-section of returns are...

We offer an investment-based interpretation of price and earnings momentum. The neoclassical theory of investment implies that expected stock returns are tied with the expected marginal benefit of investment divided by the marginal cost of investment. Winners have higher expected growth and...

The neoclassical investment model matches cross-sectional asset prices both in first differences and in levels. With ten book-to-market deciles as the testing portfolios, the investment model largely matches the Tobin's Q spread, while maintaining a good fit for the average return spread across...

An investment factor, long in low investment stocks and short in high investment stocks, helps explain the new issues puzzle. Adding this factor into standard factor regressions reduces substantially the magnitude of the underperformance following equity and debt offerings and the composite...
