Final answer:
Jane has the comparative advantage in the production of green beans because she has a lower opportunity cost than Jake for producing the same amount of green beans.
Step-by-step explanation:
Based on the provided production possibilities schedule for Jake and Jane, we can determine who has the comparative advantage in the production of green beans by comparing the opportunity cost of producing green beans for each individual. Someone has a comparative advantage in producing a good if they have a lower opportunity cost for that good than someone else. To find out who has the comparative advantage in the production of green beans, we need to compare the opportunity cost for each person. For Jake, the opportunity cost of producing 10 pounds of green beans is giving up 40 pounds of corn (160 - 120). For Jane, the opportunity cost of producing 20 pounds of green beans is 20 pounds of corn (80 - 60). If we normalize this to the opportunity cost for 10 pounds of green beans by dividing Jane's numbers by 2, Jake's opportunity cost is 40 pounds of corn for every 10 pounds of green beans, and Jane's is 10 pounds of corn for every 10 pounds of green beans. Since Jane's opportunity cost to produce the same amount of green beans is lower than Jake's, Jane has the comparative advantage in the production of green beans. We determine comparative advantage by who can produce a good at a lower opportunity cost, not by who can produce more of a good.
