This paper is a study of the impact of the weighted average cost of capital on corporate investment. Analytically q is decomposed into a cash flow component and a cost of capital component. Empirically firms with a high cost of debt and with high leverage invest less. When the cost of equity is estimated using the CAPM (or a related factor model) the cost of equity has a positive effect on investment. When the cost of equity is inferred from the Gordon growth model (or a related implied cost of equity capital) high cost of equity firms invest less.
