This paper studies the relationship between firm leverage and supplier market structure. We find that firm leverage decreases with the degree of competition between suppliers. Specifically, leverage decreases with the elasticity of substitution between suppliers. Leverage also decreases with the number of suppliers when the elasticity of substitution is high, and increases with the number of suppliers when the elasticity is low. We also provide empirical evidence that is consistent with the model predictions.
