The following graph shows the production possibilities frontier for the imaginary country of Arcadia under conditions of increasing costs. In the absence of trade, the relative cost of corn in Arcadia in terms of phones (or the marginal rate of transformation (MRT) of corn into phones) is shown by the slope of line 71, tangent to the production possibilities frontier at point A. 100 A 80 Consumption After Trade 70 CORN (Bushels) GO C B 40 30 20 10 2 6 8 10 12 14 16 18 20 PHONESWhich of the following most accurately describes Arcadia's economy in the absence of trade? Arcadia produces 78 bushels of corn but consumes only 60 bushels of corn. Arcadia produces and consumes 6 phones and 60 bushels of corn. Arcadia consumes 6 phones and 78 bushels of corn. O Arcadia produces 6 phones and 78 bushels of corn. Arcadia produces and consumes 6 phones and 78 bushels of corn. At point A, the slope of line 71 reveals that Arcadia must forego bushels of corn in order to produce 1 phone. (Hint: Select a line to see its slope.) Suppose that Arcadia recognizes that it has a comparative advantage in the production of phones. Arcadia decides to specialize in making phones and enters international trade. The international terms of trade (the price of corn in terms of phones) are shown by the slope of the line (2, tangent to the production possibilities frontier at point B. The slope of 12 reveals that now Arcadia foregoes bushels of corn in order to produce 1 phone. This means that the absolute value of the production possibilities frontier's slope Assume that Arcadia chooses to consume the same number of phones as it did in the absence of trade. On the previous graph, use the purple point (diamond symbol) to indicate Arcadia's consumption after trade. According to the graph, Arcadia's production gain from specialization is , and its consumption gain from trade is
