Vertical Differentiation With A Positional Good

Listed author(s):
  • L. Lambertini
  • R. Orsini

We investigate the role of positional effects in a market for vertically differentiated goods. We consider the two alternative settings, a single-product monopoly and a single-product duopoly. We evaluate the performance of both regimes against social planning. Contrary to conventional wisdom, we establish that it can be socially inefficient to expand the product range.
