AI, Business Strategy, and Ethics Practice Exam

The idea tested here is how some competitive advantages become self-reinforcing and can lead to winner-takes-most dynamics: economies of scale and network effects. Economies of scale happen when increasing production lowers average costs, letting larger players offer lower prices or reinvest more aggressively, which pushes competitors with smaller scale out of the market. Network effects occur when the value of a product or platform grows as more people use it—think social networks, payment networks, or operating systems—so each additional user makes the offering more attractive to everyone else. These two forces together create a powerful barrier to entry and a path for dominance: the big can get bigger, the value proposition strengthens with scale and adoption, and newcomers find it hard to overcome the entrenched position.

Other factors can influence competition, but they don’t inherently generate the same self-reinforcing dominance. Brand reputation and customer loyalty matter, yet they can be built over time by competitors and can be eroded. Regulatory protections and patent ownership can create barriers, but they are often finite or subject to legal change. Distribution access and supplier power influence market dynamics, but they don’t automatically produce the kind of escalating value that scales and networks do.
