Answer:
The answer is "Both potatoes and wheat"
Step-by-step explanation:
- The actual value of US production is a productivity gain, which is the value of potatoes and wheat, since it will yield more with a given day than in Ireland.
- Unless the country has it, otherwise nation A (USA) created the product more for country B (Ireland), the benefit between two commodities.
- Instead of the national comparative benefit, foreign trade is based on the concept of competitive advantage.
