The Strategic Effect of Bundling: A New Perspective

This paper investigates the strategic effect of the bundling strategy that is adopted by a multi-product firm that produces two complementary goods and faces one single-product rival in each market. I consider both the Cournot and Bertrand cases. When firms compete in quantities, bundling is completely ineffective. Under price competition, selling as a package is profitable when market competition is particularly tough. In such circumstances, the multi-product firm resorts to bundling to dampen the negative impact of low brand differentiation and/or scarce product complementarity. However, overall prices increase as a result of bundling, and not only consumer surplus, but also total social welfare, shrink. Copyright Springer Science+Business Media New York 2013
