We investigate a general multiple security equilibrium model in which firms adjust their capital stock in response to economic shocks. Asset values are determined by competitive risk-averse investors. When corporate capital increases in value, firms react by creating more of it. This leads to additional risk that must be borne by investors. Overall, the model generates a VAR(1) structure for the state variables determining the cross-section of expected returns, and is broadly consistent with stylized facts (e.g., the value premium, size premium, earnings momentum, and investment premium). In addition, the paper tests a new prediction of the model and finds support for it in the data.
