Draw and explain a production possibilities frontier for an economy that produces cheese and milk. What happens to this frontier if a disease kills half of the economy’s cows? (1 Mark) Use a production possibilities frontier to describe the idea of “efficiency

(Shape of the PPF) Suppose a production possibilitiesfrontier includes the following combinations:Cars                         Washing Machines0                                   1,000100                                 600200                                     0a. Graph the PPF, assuming that it has no curvedsegments.b. What is the cost of producing an additional car when50 cars are being produced?

Complete the following table by indicating whether each point represents output combinations that are inefficient, efficient, attainable, or not attainable. Check all that apply. Inefficient Efficient Attainable Not attainable Point A B E F O O (O

6. Shifts in production possibilities Suppose Argentina produces two types of goods: agricultural and capital. The following diagram shows its current production possibilities curve (PPC) for barley, an agricultural good, and airplanes, a capital good. Drag the production possibilities curve (PPC) on the graph to show the effects of a time-saving innovation in the manufacturing of airplanes. 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. AIRPLANES (Thousands) 180 150 120 8 O 60 30 0 0 70 PPC 140 210 280 BARLEY (Millions of bushels) 350 420 PPC

2. Comparative and absolute advantage David and Morgan are farmers. Each one owns a 16-acre plot of land. The following table shows the amount of squash and maize each farmer can produce per year on a given acre. Each farmer chooses whether to devote all acres to producing squash or maize or to produce squash on some of the land and maize on the rest. David Morgan Squash (Pounds per acre) 8 28 Maize (Pounds per acre) 8 7

8. Economic growth The following graph shows the production possibilities curve (also known as the production possibilities frontier) of an economy that produces cars and computers. Suppose that a rise in this economy's saving rate allows for investment in modern, efficient manufacturing plants. Adjust the production possibilities curve (PPC) to show the economy's new production possibilities after the rise in the saving rate. 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. QUANTITY OF CARS (Mor) 24 PPC 5 10 QUANTITY OF COMPUTERS (Mor) 15 Suppose society faces a broad tradeoff between allocating resources to the production of investment goods (computers) and consumption goods (cars) before the rise in the saving rate described above. Which of the following events…
