Asset Pricing Implications of Firms' Financing Constraints

We use a production-based asset pricing model to investigatewhether financing constraints are quantitatively important forthe cross-section of returns. Specifically, we use GMM to explorethe stochastic Euler equation imposed on returns by optimalinvestment. Our methods can identify the impact of financialfrictions on the stochastic discount factor with cyclical variationsin cost of external funds. We find that financing frictionsprovide a common factor that improves the pricing of cross-sectionalreturns. Moreover, the shadow cost of external funds exhibitsstrong procyclical variation, so that financial frictions aremore important in relatively good economic conditions. (JELE22, E44, G12)
