The main result of this study is that a financial constraint may serve as a
disciplining device on the internal efficiency of a firm, and the tougher
the product market competition, the higher the disciplining power. This lim
ited liability mechanism may, in part, account for the alleged disciplining
power of product market competition on firm efficiency. However, even if p
olicies that promote competition enhance x-efficiency, the gain may be outw
eighed by a less efficient allocation of risk. Moreover, this adverse risk-
effect has repercussions, implying that the effect of reduced entry barrier
s on competition and consumer's welfare is small. (C) 2000 Elsevier Science
