Suppose that there is a Production Possibility Frontier drawn with milk on the vertical axis and beef on the horizontal axis. The PPF has the usual concave shape. A new beef preparing technique is developed that assists with the production of beef, but is of no use to milk production. How will this shift the PPF? The PPF has the same vertical intercept, and shifts outwards at other points The PPF will not move The PPF has the same horizontal intercept, and shifts outwards at other points The PPF will shift outwards at all points
