Final answer:
False. The resource-based model does not assume that if firms have rare or costly to imitate resources, this is sufficient for competitive advantage.
Step-by-step explanation:
False. The resource-based model does not assume that if firms have resources that are rare or costly to imitate, this is sufficient to form a basis for competitive advantage. The model actually suggests that resources must also be valuable and organized effectively to create a sustainable competitive advantage. Rare and costly to imitate resources are necessary conditions, but not sufficient. For example, a firm may have a rare and costly to imitate resource like patented technology, but if it is not valuable in the marketplace or if the firm fails to organize and utilize the resource effectively, it may not lead to a competitive advantage.
