“…In equilibrium, both high quality and low quality firms pledge, but in very different ways: high quality firms pledge to maintain a lower degree of leverage in order to keep available collateral capacity, and low quality firms pledge by offering more collateral. This helps to explain the seemingly surprising results in Berger and Udell (1990) and John, Lynch, and Puri (2003), who find that interest rate increases with collateral. In contrast, Benmelech and Bergman (2009) show that, conditioning on the firm pledging collateral, better collateral carries lower interest rate, which is in line with our theory.…”
