For an even number of firms with identical transport cost, spatial Cournot competition in a circular city generates a continuum of equilibria. We establish that any transport cost differential between the firms, however small, may eliminate all the equilibria, except the partial agglomeration...

This article reconsiders the linear new economic geography model under heterogeneous agents developed by Tabuchi and Thisse (2002) by applying an analytical technique introduced by Ludema and Wooton (1999). Two problematic aspects are identified: first, the divergence pattern for countries which...

This paper studies an effect of a horizontal merger where a product consolidation by the merged firm may alter the substitutability in the industry. We show that as the number of firms in the industry increases, this type of merger becomes profitable for merging firms, while unprofitable for...

This paper studies the stability of mergers between firms in a Cournot market. Unlike most existing works, we consider a demand structure where the substitutability between firms is asymmetric. We specifically focus on the stability of the grand coalition by analyzing the core allocation. The...
