Selection,Market Size and International Integration: Do Vertical Linkages Play a Role?
Authors:Antonella Nocco
Abstract:We analyze how increases in the market size and in the level of international integration affect the process of selection among firms with heterogeneous productivity levels when they are interconnected by vertical linkages. We show that when vertical linkages among firms are relatively weak (strong), an increase in the market size softens (toughens) the competition facing firms in this market and more firms of a lower (higher) efficiency survive, increasing (decreasing) the welfare level. Moreover, an increase in the level of economic integration softens competition only for intermediate vertical linkages, worsening the welfare level only for strong linkages.
