초록
Several studies on mixed oligopoly indicate that the ownership pattern of firms does not affect the equilibrium price. This idea often suggests that ownership is irrelevant. In a mixed duopoly under price competition, firm ownership is irrelevant. This study reveals that ownership is irrelevant in a single publicly owned firm and in any positive number of privately owned firms. However, if two or more publicly owned firms exist, then ownership becomes relevant in a homogeneous good market with a strictly increasing convex cost schedule and a downward sloping demand curve. If firms set the price sequentially and if the lone public firm is a price leader, then social welfare is constantly greater than when the latter is a price follower. The unique price is the competitive price when the public firm moves first in the sequential game.
Abstract
Several studies on mixed oligopoly indicate that the ownership pattern of firms does not affect the equilibrium price. This idea often suggests that ownership is irrelevant. In a mixed duopoly under price competition, firm ownership is irrelevant. This study reveals that ownership is irrelevant in a single publicly owned firm and in any positive number of privately owned firms. However, if two or more publicly owned firms exist, then ownership becomes relevant in a homogeneous good market with a strictly increasing convex cost schedule and a downward sloping demand curve. If firms set the price sequentially and if the lone public firm is a price leader, then social welfare is constantly greater than when the latter is a price follower. The unique price is the competitive price when the public firm moves first in the sequential game.
