Two-firm horizontal Cournot mergers give rise to multi-plant firms in spatial markets. We study location equilibria on the circle for competition between a two-store merged entity and one then two single-store competitors. Several results turn up. First of all, we get equilibrium location...

Mergers and spin-offs are typically opposite strategies for firms, and are not simultaneously profitable in a standard linear Cournot model. We propose a simple spatial Cournot framework, where merger is profitable but subsequent divisionalization is even more. However, this is true only for...

It is proved that the irrelevance result of Poyago-Theotoky can be extended from the linear-quadratic case to general inverse demand and cost functions. Hence, as long as firms are profitable at the first-best, the optimal subsidy decentralizes it in mixed oligopoly irrespecitve of whether the...

White (1996), Poyago-Theotoky (2001) and Myles (2002) prove that in the mixed oligopoly the optimal subsidy, equilibrium output level, all firms' profits and social welfare are identical irrespective of whether the public firm maximizes welfare or profit and moves simultaneously with private...
