They must be rare among a firm’s current and potential competition. This simply means that this resource or strategy cannot be implemented by other firms at the same time. 3 They must be imperfectly imitable (hard to copy for other firms) and 4. There cannot be strategically equivalent substitutes for this resource that are valuable, but neither rare or imperfectly imitable. Can anyone think of a specific firm, or a type of business or industry, which has a clear example of sustained competitive advantage? Short discussion.
We thought about what kind of a firm could gain a sustained competitive advantage, and came to the conclusion that certain pharmaceutical companies are able to gain perfect sustained competitive advantage. To explain why, we need to have a look at the pharmaceutical market. To make things a bit simple, we can divide the industry into two different categories: Companies which develop new kinds of medicine, and others which copy the original medicine, and produce what...
