A farm grows corn and produces eggs. The marginal cost of producing each of these products increases as more of it is produced.

a. Make a graph that illustrates the farm’s PPF .

b. The farm adopts a genetically modified method that allows it to increase its corn yield.

On your graph, sketch the impact of this new method on the farm’s PPF .

c. With the farm using the new method described in part (b), has the opportunity cost of producing a carton of eggs increased, decreased, or remained the same? Explain and illustrate your answer.

d. Is the farm more efficient with the new method of genetic engineering than it was without it? Why?
