Bundling (Economics)
Bundling is the practice of selling two or more products together as a single package. It can extract more total revenue from heterogeneous buyers than separate sales, and is especially powerful for information goods whose marginal cost is near zero.
Bundling is a pricing strategy in which a seller offers multiple distinct products together at a single price. Pure bundling sells the components only as a package (a cable TV lineup, a stadium season ticket); mixed bundling offers both the bundle and the individual items, usually with the bundle priced below the sum of its parts. Familiar examples include Microsoft Office, fast-food combo meals, streaming-service catalogs, academic journal "big deals," and cable-channel packages. Economically, bundling can be profitable when buyers differ in how they value the components. By forcing them to buy the bundle, the seller smooths out individual valuations and extracts more total consumer surplus than per-item pricing — a result formalized by George Stigler in 1963 and developed by William Baumol, Yannis Bakos, and Erik Brynjolfsson for information goods in particular. Because the Marginal Cost of Digital Reproduction of adding another title to a digital bundle is near zero, the seller can include even low-value items without meaningfully raising cost, while pulling in buyers who would not have purchased them separately. Bundling also functions as price discrimination, a defensive move against competitors (raising switching costs), and a way to leverage market power from a strong product into a weaker one — which is why bundling has periodically attracted antitrust attention, as in the United States v. Microsoft case over Internet Explorer and Windows. Related strategies include tying, Freemium tiering, and versioning.
