Answer:
Competitive Advantage
Step-by-step explanation:
A competitive advantage refers to a condition that allows a company (e.g. St. Jude Medical) to offer better products than the competition at the same price, or offer similar products at a lower price.
In this specific case, St. Jude Medical is able to sell better products (mechanical heart valves, tissue heart valves, pacemakers, and implantable cardiovascular defibrillators) at similar prices than its competitors.
If a company offers a better product at a higher price, they do not have any type of competitive advantage. Competitive advantages result from higher efficiency and lower opportunity costs.
