A More General Theory of Commodity Bundling

  • Mark Armstrong

This paper discusses the incentive to bundle when consumer valuations are non-additive and/or when products are supplied by separate sellers.� Whether integrated or separate, a firm has an incentive to introduce a bundle discount when demand for the bundle is more elastic than the overall demand for products.� When separate sellers coordinate on a bundle discount, they can use the discount to relax competition, which can harm welfare.
