Answer:
absolute advantage
Step-by-step explanation:
Until recently, the United States could produce oil-drilling equipment more efficiently than other countries, and, in a sense, monopolized the industry. In the market for oil-drilling equipment the United States had an absolute advantage.
Absolute advantage can be defined as the capability to produce more of a given product using less of a given resource than a competing entity. on the other hand, comparative advantage refers to the ability of a party to produce a particular good or service at a lower opportunity cost over another.
Looking at the scenario, what applies is absolute advantage because it mentions that production is done more efficiently by the United States. Efficiency relates to using less inputs to get more output which is characteristic of absolute advantage.
