Abstract

This paper investigates how an incumbent monopolistic can weaken potential rivals or deter entry in the output market by manipulating the access of these rivals in the input market. We analyze two polar cases. In the first one, the input market is assumed to be competitive with the input being supplied inelastically. We show that the situation opens the door to entry deterrence. Then, we assume that the input is supplied by a single seller who chooses the input price. In this case we show that entry deterrence can be reached only through merger with the seller of the input.
