Ma. Petersen et Rg. Rajan, THE EFFECT OF CREDIT MARKET COMPETITION ON LENDING RELATIONSHIPS, The Quarterly journal of economics, 110(2), 1995, pp. 407-443
This paper provides a simple framework showing that the extent of comp
etition in credit markets is important in determining the value of len
ding relationships. Creditors are more likely to finance credit-constr
ained firms when credit markets are concentrated because it is easier
for these creditors to internalize the benefits of assisting the firms
. The paper offers evidence from small business data in support of thi
s hypothesis.
