Diverting some resources away from A to B causes relatively little reduction in health because the last few marginal dollars going into healthcare services are not producing much additional gain in health. But additional increases after that typically causerelatively smaller reductions in crime, and paying for enough police and security to reduce crime to zerowould be tremendously expensive. However, additional increases typically cause relatively larger increases in the opportunity cost of reducing crime, and paying for enough police and security to reduce crime to nothing at all would be a tremendously high opportunity cost. It is the amount of the good on the vertical axis that must be given up in order to free up the resources required to produce one more unit of the good on the horizontal axis. Plant 3 would be the last plant converted to ski production. If the firm wishes to increase snowboard production, it will first use Plant 3, which has a comparative advantage in snowboards. d. used to produce consumption goods. More generally, as society produces more and more of some good or service, the cost of production grows larger and larger relative to the cost of producing other goods or services. We may conclude that, as the economy moved along this curve in the direction of greater production of security, the opportunity cost of the additional security began to increase. all the doctors and all the teachers) are devoted to providinghealth care and none isleft for education. A concave curve is one that bends outward from the origin. If you use it this way . In the chapter on International Trade you will learn that countries differences in comparative advantage determine which goods they will choose to produce and trade. Productive efficiency means it is impossible to produce more of one good without decreasing the quantity that is produced of another good. Why is a production possibilities frontier typically drawn as a curve, rather than a straight line? Neither skis nor snowboards is an independent or a dependent variable in the production possibilities model; we can assign either one to the vertical or to the horizontal axis. Figure 1. 2.4: The Ricardian Model Production Possibility Frontier Wed love your input. (Scarcity principle) The slope of the PPC measures all possible combinations of two goods, which an economy can produce with available resources. Want to cite, share, or modify this book? In Welcome to Economics! Watch this video to see another explanation as to why the PPF is curved. Often how much of a good a country decides to produce depends on how expensive it is to produce it versus buying it from a different country. Notice also that this curve has no numbers. An economys factors of production are scarce; they cannot produce an unlimited quantity of goods and services. The plant with the lowest opportunity cost of producing snowboards is Plant 3; its slope of 0.5 means that Ms. Ryder must give up half a pair of skis in that plant to produce an additional snowboard. PDF Microeconomics 12th Edition Arnold Test Bank In that case, it produces no snowboards. That is the tradeoff society faces. By 1933, more than 25% of the nations workers had lost their jobs. In the summer of 1929, however, things started going wrong. In the first case, a society may discover that it has been using its resources inefficiently, in which case by improving efficiency and producing on the production possibilities frontier, it can have more of all goods (or at least more of some and less of none). Just as with Alphonsos budget constraint, the slope of the production possibilities frontier shows the opportunity cost. The opportunity cost would be the healthcare society has to give up. The most important difference between the two graphs, though, is that a budget constraint is a straight line, while a production possibilities curve is typically bowed outwards, i.e. Such an allocation implies that the law of increasing opportunity cost will hold. The PPF is downward sloping because it depicts the trade-off between two products. However, putting those marginal dollars into education, which is completely without resources at point A, can produce relatively large gains.

The production possibilities curve shown suggests an economy that can produce two goods, food and clothing. Suppose society has chosen to operate at point B, and it is considering producing more education. Society can choose any combination of the two goods on or inside the PPF, but it doesnthave enough resources to produce outside the PPF. Figure 2.4 illustrates these ideas using a production possibilities frontier between healthcare and education. If all the factors of production that are available for use under current market conditions are being utilized, the economy has achieved full employment. At A all resources go to healthcare and at B, most go to healthcare. Bowed when -factors of production are heterogeneous (Some laborers are better at one thing than the other) OR Similarly, as additional resources are added to healthcare, moving from bottom to top on the vertical axis, the original gains are fairly large, but again gradually diminish. Suppose Alpine Sports expands to 10 plants, each with a linear production possibilities curve. To find this quantity, we add up the values at the vertical intercepts of each of the production possibilities curves in Figure 2.4 Production Possibilities at Three Plants. In such a case, more of one good can be produced only by taking resources away from the production of another good. A movement from A to B requires shifting resources out of the production of all other goods and services and into spending on security. A PPF is more likely to be a downward-sloping curve that is bowed outward than a downward-sloping straight line because most resources are. https://cnx.org/contents/vEmOH-_p@4.44:BxoHdm8G@8/The-Production-Possibilities-F, https://www.flickr.com/photos/senoranderson/3890652995/, https://www.youtube.com/watch?v=Nw0ugthoc8o, https://www.youtube.com/watch?time_continue=6&v=nsQi2ipSP2c, Explain the production possibilities frontier. This situation is illustrated by the production possibilities frontier in Figure 1. This pattern is so common that it has been given a name: thelaw of diminishing returns. The reason for this difference is pretty simple: the slope of a budget line is defined as the ratio of the prices of the two goods or services. The curve is a downward-sloping straight line, indicating that there is a linear, negative relationship between the production of the two goods. Every economy faces two situations in which it may be able to expand consumption of all goods. For the sake of concreteness, you can imagine that in the movement from D to F, the last few doctors must become high school science teachers, the last few nurses must become school librarians rather than dispensers of vaccinations, and the last few emergency rooms are turned into kindergartens. PPC is downward sloping because production of one item can be increased only after sacrificing some of the other good. Suppose it considers moving from point B to point C. . What happen if society wants less products than what are on the productive efficiency point? If it fails to do that, it will operate inside the curve. Why is a PPF curve concave? - KnowledgeBurrow.com In an actual economy, with a tremendous number of firms and workers, it is easy to see that the production possibilities curve will be smooth. Suppose a society desires two products: health care and education. Over time, a growing economy will tend to shift the PPF outwards. All choices along a production possibilities frontier display productive efficiency; that is, it is impossible to use societys resources to produce more of one good without decreasing production of the other good. For this reason, the shape of the PPF from A to B is relatively flat, representing a relatively small drop-off in health and a relatively large gain in education. When factors of production are allocated on a basis other than comparative advantage, the result is inefficient production. For society, there are many scarce resources. In this section, we shall assume that the economy operates on its production possibilities curve so that an increase in the production of one good in the model implies a reduction in the production of the other. The U.S. has comparative advantage in wheat and Brazil has comparative advantage in sugar cane. Inefficient production implies that the economy could be producing more goods without using any additional labor, capital, or natural resources. If on the one hand, very few resources are currently committed to education, then an increase in resources used can bring relatively large gains. When countries engage in trade, they specialize in the production of the goods in which they have comparative advantage, and trade part of that production for goods in which they do not have comparative advantage. By now you might be saying, Hey, this PPF is sounding like the budget constraint. If so, read the following Clear It Up feature. Conversely, the U.S. can produce a lot of wheat per acre, but not much sugar cane. PPF slopes downwards: PPF shows all the maximum possible combination of two goods, which can be produced with the available resources and technology. Here they are, the 100 best restaurants in New York City, ranked. Considering the situation in Figure 1 (shown again below), suppose we have only two types of resources: doctors and teachers. Just as individuals cannot have everything they want and must instead make choices, society as a whole cannot have everything it might want, either. The study of economics does not presume to tell a society what choice it. While the slope is not constant throughout the PPFs, it is quite apparent that the PPF in Brazil is much steeper than in the U.S., and therefore the opportunity cost of wheat is generally higher in Brazil. She also modified the first plant so that it could produce both snowboards and skis. Between 1929 and 1942, the economy produced 25% fewer goods and services than it would have if its resources had been fully employed. More generally, the absolute value of the slope of any production possibilities curve at any point gives the opportunity cost of an additional unit of the good on the horizontal axis, measured in terms of the number of units of the good on the vertical axis that must be forgone. We recommend using a Law of Increasing Opportunity Cost - Study.com Suppose the firm decides to produce 100 radios. Why is the PPF downward sloping? Suppose society has chosen to operate at point B, and its considering producing more education. Would you be able to consume what you consume now? We would say one teacher could produce 25 students worth of education using the education processes available. The result is a far greater quantity of goods and services than would be available without this specialization. An Emerging Consensus: Macroeconomics for the Twenty-First Century, 33.1 The Nature and Challenge of Economic Development, 33.2 Population Growth and Economic Development, 34.1 The Theory and Practice of Socialism, 34.3 Economies in Transition: China and Russia, Appendix A.1: How to Construct and Interpret Graphs, Appendix A.2: Nonlinear Relationships and Graphs without Numbers, Appendix A.3: Using Graphs and Charts to Show Values of Variables, Appendix B: Extensions of the Aggregate Expenditures Model, Appendix B.2: The Aggregate Expenditures Model and Fiscal Policy. Figure 2. c. relatively cheap at low levels of output. When government spends a certain amount more on reducing crime, for example, the original increase in opportunity cost of reducing crime could be relatively small. In the second case, as resources grow over a period of years (e.g., more labor and more capital), the economy grows. The curve of the production possibilities frontier shows that as additional resources are added to education, moving from left to right along the horizontal axis, the initialgains are fairly large, but those gains gradually diminish. It can shift to ski production at a relatively low cost at first. With all three plants producing only snowboards, the firm is at point D on the combined production possibilities curve, producing 300 snowboards per month and no skis. we learned that every society faces the problem of scarcity, where limited resources conflict with unlimited needs and wants. PPF has a negative slope due to it's downward sloping nature. In the first case, a society may discover that it has been using its resources inefficiently, in which case by improving efficiency and producing on the production possibilities frontier, it can have more of all goods (or at least more of some and less of none). This lawasserts that as additional increments of resources are devotedto a certain purpose, the marginal benefit from those additional increments will decline. We will generally draw production possibilities curves for the economy as smooth, bowed-out curves, like the one in Panel (b). Could a nation be producing in a way that is allocatively efficient, but productively inefficient? Were now readyto address the differences between societys PPF and an individuals budget constraint. In drawing production possibilities curves for the economy, we shall generally assume they are smooth and bowed out, as in Panel (b). Why is PPF downward sloping? Just because you can make a billion phones because it is along the PPF curve is not reasonable. When can PPC be a straight line? Choices outside the PPF are unattainable and choices inside the PPF are wasteful. Solved A PPF is more likely to be a downward-sloping curve - Chegg When an economy is operating on its production possibilities curve, we say that it is engaging in efficient production. Clearly, the transfer of resources to the effort to enhance national security reduces the quantity of other goods and services that can be produced. Because the production possibilities curve for Plant 1 is linear, we can compute the slope between any two points on the curve and get the same result. Want to create or adapt books like this? That is the tradeoff society faces. The lesson is not that society is likely to make an extreme choice like devoting no resources to education at point A or no resources to health at point F. Instead, the lesson is that the gains from committing additional marginal resources to education depend on how much is already being spent. It is clear that productive inefficiency is a waste since resources are being used in a way that produces less goods and services than a nation is capable of. At point A, all available resources (i.e. To understand why the PPF is curved, start by considering point A at the top left-hand side of the PPF. In microeconomics, a production-possibility frontier ( PPF ), production possibility curve ( PPC ), or production possibility boundary ( PPB) is a graphical representation showing all the possible options of output for two goods that can be produced using all factors of production, where the given resources are fully and . In effect, the production possibilities frontier plays the same role for society as the budget constraint plays for Alphonso. The opportunity cost of an additional snowboard at each plant equals the absolute values of these slopes (that is, the number of pairs of skis that must be given up per snowboard). Thus, the production possibilities curve not only shows what can be produced; it provides insight into how goods and services should be produced. But the amount of education gained is great, because thats what teachers are trained for. Even though each of the plants has a linear curve, combining them according to comparative advantage, as we did with 3 plants in Figure 2.5 The Combined Production Possibilities Curve for Alpine Sports, produces what appears to be a smooth, nonlinear curve, even though it is made up of linear segments. Suppose it begins at point D, producing 300 snowboards per month and no skis. The PPF is downward sloping because it depicts the trade-off between two products. Suppose that, as before, Alpine Sports has been producing only skis. If it were to allocate all of its resources to education, it could produce at point F. Alternatively, the society could choose to produce any combination of healthcare and education shown on the production possibilities frontier. The table shows the combinations of pairs of skis and snowboards that Plant 1 is capable of producing each month. Why does the shape of the ppf slope downwards to the right - Answers And is this the case of allocative inefficiency? Because the PPF is downward sloping from left to right, the only way society can obtain more education is by giving up some healthcare. In effect, the production possibilities frontier plays the same role for society as the budget constraint plays for Alphonso. Direct link to Joshua's post The PPF graph is major si, Posted 2 years ago. While the slope is not constant throughout the PPFs, it is quite apparent that the PPF in Brazil is much steeper than in the U.S., and therefore the opportunity cost of wheat is generally higher in Brazil. Plant 3, though, is the least efficient of the three in ski production. Because the PPF is downward sloping from left to right, the only way society can obtain more education is by giving up some health care. Comparative advantage is not the same as absolute advantage, which is when a country can produce more of a good. Notice that this production possibilities curve, which is made up of linear segments from each assembly plant, has a bowed-out shape; the absolute value of its slope increases as Alpine Sports produces more and more snowboards. Suppose there is an improvement in medical technology that enables more healthcare to be provided with the same amount of resources. Explain the concept of the production possibilities curve and understand the implications of its downward slope and bowed-out shape.
