Abstract

We analyze productivity-improving mergers in mixed triopoly and explore stable market structures. We find the only stable market structure contains a merged public-private firm and one private firm with about 57% of shares owned by the public firm.

Key words: mergers; mixed oligopoly; the core of market structures
JEL classification: D21; L13; L33
