Answer:
Differential competitive advantage.
Explanation:
A differential competitive advantage can be defined as the advantages or edge that a business or company gains as a result of providing (offering) superior goods and services that are unique, cheaper and different from that of its rivals in the same industry.
Some of the factors that enhances or contributes to differential competitive advantage that a company has over its rivals include patent, new technology, experienced employees, professionals or experts, brand identity etc.
Hence, a firm with a differential competitive advantage has its ability to provide a unique product or service that offers something of value to buyers besides simply a lower price.
An example of a company with differential competitive advantage in the mobile market is Apple Inc. through the production of iPhone.
