Final answer:
Dunkin' Donuts and Subway sharing space exemplifies a multi-brand strategy, leveraging the advantages of shared spaces and resources, and catering to a diverse customer base.
Step-by-step explanation:
Firms like Dunkin' Donuts and Subway sharing space with quick service restaurants is an example of a multi-brand strategy. This approach involves multiple brands working under a single umbrella or within the same space, which can be advantageous for maximizing the usage of space, catering to diverse customer preferences, and potentially saving costs through shared resources. Such a strategy stands in contrast to a single-source market, economies of scale, mini-stores, and economies of scope, though it may share certain characteristics such as diversification with the latter. Restaurants, especially those that operate as franchises, frequently pursue such strategies to broaden their market reach and brand presence, capitalizing on the firms' established reputations and consumer loyalties.
