The welfare impact of a merger involves the market power offense and the efficiency defense. Salant et al. (1983) show … for a profitable merger to increase welfare but leave open whether it exists.

Monopolistic competition in general equilibrium: beyond the CES
ZHELOBODKO, Evgeny; KOKOVIN, Sergey; PARENTI, Mathieu; … - Center for Operations Research and Econometrics (CORE), … - 2011
We propose a general model of monopolistic competition and derive a complete characterization of the market equilibrium using the concept of Relative Love for Variety. When the RLV increases with individual consumption, the market generates pro-competitive effects. When it decreases, the market...

Verti-zontal differentiation in export markets
DI COMITE, Francesco; THISSE, Jacques - Center for Operations Research and Econometrics (CORE), … - 2013
Many trade models of monopolistic competition identify cost efficiency as the main determinant of firm performance in export markets. To date, the analysis of demand factors has received much less attention. We propose a new model where consumer preferences are asymmetric across varieties and...

Comparative Advantage under Oligopoly
CORDELLA, Tito; GABSZEWICZ, Jean - Center for Operations Research and Econometrics (CORE), … - 1993
We analyze the principle of comparative advantage when agents in the world market are aware of the influence their individual supply exerts on the equilibrium exchange rate of goods. We show that specialization following comparative disadvantage can be an oligopoly equilibrium in a Ricardian...

Home market effect versus multinationals
TOULEMONDE, Eric - Center for Operations Research and Econometrics (CORE), … - 2007
In this paper, based on the cyclic scheduling formulation of Schilling and Pantelides [22], we propose a continuous time mixed integer linear programming (MILP) formulation for the cyclic scheduling of a mixed plant, i.e. a plant composed of batch and continuous tasks. The cycle duration is a...

Welfare, home market effects, and horizontal foreign direct investment
BEHRENS, Kristian; PICARD, Pierre M. - Center for Operations Research and Econometrics (CORE), … - 2005
We investigate the spatial distribution and organization of an imperfectly competitive industry when firms may choose to operate more than a single production unit. Focusing on a short-run setting with a fixed mass of firms, we fully characterize the spatial equilibria analytically. Comparing...
