Does trade credit facilitate access to bank finance? An empirical evidence from Portuguese and Spanish small medium size enterprises

This paper examines if trade credit is as a substitute and/or a complement to bank credit in order to assess the existence of credit rationing. Using a panel dataset of 468 and 7019 Portuguese and Spanish small medium size enterprises for the period 1998-2006, and controlling for endogeneity problems by using GMM estimators, the results confirm the existence of credit rationing, since the substitution hypothesis is confirmed. This effect is particularly strong for firms that maintaining an exclusive relationship with one bank, which indicate a greater severity of adverse selection problems for those firms. Although the substitution hypothesis is confirmed, the results also indicate that the substitution and complementary hypothesis are not mutually exclusive, especially for a specific group of firms: the younger and smaller firms. In line with the theories that emphasize the informational role of trade credit, due the informative advantage of suppliers, our empirical results confirm that trade credit allow the younger and smaller firms to improve their reputation, as trade credit reveals the private information of the supplier to the bank, in turn, banks can update their beliefs about customer default risk and agree to increase bank credit.
