What is the marginal cost of harvesting corn for each individual? For producing tomatoes? c. Who has the comparative advantage in harvesting corn? In producing tomatoes? Explain your reasoning. d. Draw individual PPF’s for both Anna and Bob. Explain the relationship between the slope of the PPF and marginal cost for each person. e. Create an Economy-Wide PPF.
