Without trade, the farmer produced and consumed 2 pounds of pork and 4 pounds of tomatoes and the rancher produced and consumed 4 pounds of pork and 2 pounds of tomatoes. then, each person agreed to specialize in the production of the good in which he has a comparative advantage and trade 4 pounds of pork for 6 pounds of tomatoes. as a result,

the farmer gained 6 hours worth of production and the rancher gained 8 hours worth of production.

Explanation:

Labor Hours to Make 1 lb. of lbs. Produced in 24 Hours

Pork Tomatoes Pork Tomatoes

Farmer 6 3 4 8

Rancher 4 4 6 6

If both decide to specialize in producing only one good, the farmer will produce 8 pounds of tomatoes per day and the rancher will produce 6 pounds of pork per day.

This way when the rancher trades 4 pounds of pork in exchange for 6 pounds of tomatoes, he is gaining 2 pounds of pork which is equivalent to 8 labor hours.

When the rancher trades 6 pounds of tomatoes in exchange for 4 pounds of pork, he is gaining 2 pounds of tomatoes which is equivalent to 6 labor hours.
