Answer:
Airbus benefits from first-mover advantage.
Step-by-step explanation:
First-mover advantage is the advantage of a pioneer firm gains by purchasing resources early or building technological leadership. The firm is then rewarded with monopoly-like status or very large profit margins.
In this case Aribus is the technological leader for developoing the superjumbo jet first. And it is rewarded with monopoly status because Boeing has been effectively shut out.
