Economies of scope ? or scale

First cousin to economies of scale is economies of scope, factor that make it cheaper to produce a range of products together than to produce each one of them on its own. Such economies can come from businesses sharing centralised functions, such as finance or marketing. Or they can come from interrelationships elsewhere in the business process, such as cross-selling one product alongside another, or using the outputs of one business as the inputs of another.

The idea of economies of scope has been the underpinning for other sorts of corporate behaviour including mass production and Merger & Acquisitions, but particularly diversification. The desire to garner economies of scope was the driving force behind the vast international conglomerates built up in the 1970s and 1980s, including BTR and Hanson in the UK and ITT in the United States. The logic behind these amalgamations lay mostly in the scope for the companies to leverage their financial skills across a diversified range of industries.

A number of conglomerates put together in the 1990s relied on cross-selling, thus reaping economies of scope by using the same people and systems to market many different products. The combination of Travelers Group and Citicorp in 1998, for instance, was based on the logic of selling the financial products of the one by using the sales teams of the other.
