Question

(i) The consumption bundles under trade are calculated as follows: John produces (15T, 7.5P) and Jane produces (20T, 5P). After the trade, John consumes (15+15=30T, 7.5-5=2.5P), while Jane consumes (20-15=5T, 5+5=10P). (ii) The question asks us to consider what would happen if John and Jane had to consume only what they produce, without trading. In this case, John can only produce (30T, 0P), but he consumes (30T, 2.5P). This means he gains a total of 2.5P. Similarly, Jane can only produce (0T, 10P), but she consumes (5T, 10P). She gains 5T. Therefore, both John and Jane would not be able to consume the quantities found in (i) if they had to consume only what they produce. (iii) The question asks if Jane would be interested in trading with John if she can produce either 40 tomatoes and 0 peppers or 0 tomatoes and 20 peppers. The answer is no because the opportunity cost (OC) for Jane is 1P=2T. This means that for every pepper she produces, she gives up the opportunity to produce 2 tomatoes. The same goes for John, whose OC is also 1P=2T. Since their OCs are the same, there is no comparative advantage, and there would be no gains from trade.
