Differentiated Bertrand markets: restoring the minimum differentiation principle

Author

  • Stefano Colombo

Abstract

I introduce non-perfect substitutability between products into the spatial Bertrand model. I show that if goods are complements, the firms always agglomerate. If goods are substitutes, the firms agglomerate if the transportation costs are not too high. Copyright Springer-Verlag Berlin Heidelberg 2013
