摘要	When facing a single-product entrant in one of its two differentiated good markets, a multi-product firm may respond by choosing among the three strategies: (i) continue to operate at the status quo with keen price competition with the entrant, (ii) exit the competing-good market and concentrate on selling its monopoly good, and (iii) bundle the two differentiated goods and only sell the bundled package. We show that if two goods are substitutes, both strategies of bundling and exiting the second-good market for the multi-product firm are better than those of the status quo. Nevertheless, if two goods are complements, the status quo and bundling two goods as a bundle are better than exiting the market. We further compare whether the multi-product firm finds it a profitable strategy to exit the competing-good market or to bundle the products as a package depends crucially on the substitutability or complementarity between the two products. In terms of welfare, we find that product bundling yields welfare superior to the other two strategies, regardless of whether the two products are substitutes or complements.
