Market Size, Technology Choice, and Market Structure

Walter Elberfeld and Georg Götz ()

German Economic Review, 2002, vol. 3, issue 1, pages 25-41

Abstract: We introduce technology choice into a model of monopolistic competition and analyze the structural effects of changes in market size. A larger market leads to the adoption of a large-scale technology. If a technology switch occurs, the number of firms decreases, and a rationalizing effect arises: individual and aggregate output increases; prices fall. This need not benefit consumers since a technology switch is associated with a decrease in product variety. Copyright Verein fü Socialpolitik and Blackwell Publishers Ltd 2002.
