5. Shifts in production possibilities Suppose the United Kingdom produces two types of goods: agricultural and capital. The following diagram shows its current production possibilities frontier for wheat, an agricultural good, and locomotives, a capital good. Drag the production possibilities frontier (PPF) on the graph to show the effects of a technological advance in medicine that allows workers to live longer and have extended careers. Note: Select either end of the curve on the graph to make the endpoints appear. Then drag one or both endpoints to the desired position. Points will snap into position, so if you try to move a point and it snaps back to its original position, just drag it a little farther. 54 " '3, 450 -- PPF 360 270 180 LOCOMOTIVES (Thousands) 0 100 200 300 400 500 600 WHEAT (Millions of bushels)
