Answer:
The opportunity cost of wheat production is lower in Nation B.
Explanation:
A country has comparative advantage in production if it produces at a lower opportunity cost when compared with other countries.
For country A,
the opportunity cost of producing wheat = 30 / 50 = 0.6
The opportunity cost of producing brick = 50 / 30 = 1.7
For country B,
the opportunity cost of producing wheat = 20 / 40 = 0.5
The opportunity cost of producing brick = 40 / 20 = 2
The least cost producer of wheat is country B
The high cost producer of brick is country B
The opportunity cost of producing wheat is lower in country B when compared to country A.
According to the law of comparative advantage, country A should specialise in the production of bricks because it has the lower opportunity cost.
