We provide a theoretical model linking firm characteristics and expected returns. The key ingredient of our model is technological shocks embodied in new capital (IST shocks), which affect the profitability of new investments. Firms' exposure to IST shocks is endogenously determined by the...

Average return differences among firms sorted on valuation ratios, past investment, prof-itability, market beta, or idiosyncratic volatility are largely driven by differences in exposures offirms to the same systematic factor related to embodied technology shocks. Using a calibratedstructural...

We extend the standard q theory of investment into a two-capital setup in which firms use both physical capital (long-term asset) and short-term capital (current asset) as production inputs. We find this simple extension is capable of explaining the stronger return predictive power of total...

Tobin's Q exceeds one, even without any adjustment costs, for a firm that earns rents as a result of monopoly power or of decreasing returns to scale in production. Even when there are no adjustment costs and marginal Q is always equal to one, Tobin's Q is informative about the firm's growth...

Empirical evidence suggests that capital separation is an important phenomenon over and beyond depreciation and that reallocation is a costly and time-consuming process. In addition, both separation and reallocation rates display substantial variation over the business cycle. We build a dynamic...
