(Scarcity principle) The slope of the PPC measures all possible combinations of two goods, which an economy can produce with available resources. Basically, what this means is that as an economy devotes more of. If we started at the other end of the PPF at point F and moved to point D, we would be moving doctors from teaching to healthcare with the result that the gain in healthcare would be large while the loss in education would be small (the same logic we used above). That's the trade-off this society faces. What is allocative efficiency? Plant R has a comparative advantage in producing calculators. 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. The absolute value of the slope of any production possibilities curve equals the opportunity cost of an additional unit of the good on the horizontal axis. Why does the PPF bow outward and what does that imply? While even smaller than the second plant, the third was primarily designed for snowboard production but could also produce skis. Now imagine that some of these resources are diverted from healthcare to education, so that the economy is at point B instead of point A. When an economy is operating on its production possibilities curve, we say that it is engaging in efficient production. The curvature of the production possibilities frontier shows that as additional resources are added to education, moving from left to right along the horizontal axis, the original gains are fairly large, but gradually diminish. How did the war affect Germanys production possibilities curve? Thus, the slope of the PPF is relatively steep near the horizontal-axis intercept. In a market-oriented economy with a democratic government, the choice will involve a mixture of decisions by individuals, firms, and government. Ski sales grew, and she also saw demand for snowboards risingparticularly after snowboard competition events were included in the 2002 Winter Olympics in Salt Lake City. Direct link to Letladi Sebesho's post In the book 'Principles o, Posted 4 years ago. An inefficient organization operates with long delays and high costs, while an efficient organization meets schedules, is focused, and performs within budget. Had the firm based its production choices on comparative advantage, it would have switched Plant 3 to snowboards and then Plant 2, so it could have operated at a point such as C. It would be producing more snowboards and more pairs of skisand using the same quantities of factors of production it was using at B. The Production Possibilities Frontier, Part 1 The Economic Lowdown Video Series. Suppose that Alpine Sports is producing 100 snowboards and 150 pairs of skis at point B. With all three of its plants producing skis, it can produce 350 pairs of skis per month (and no snowboards). If society has a total of 10 teachers, education can be provided to a maximum of 250 students. Now draw the combined curves for the two plants. Wed love your input. The slope of the PPF indicates the opportunity cost of producing one good versus the other good, and the opportunity cost can be compared to the opportunity costs of another producer to determine comparative advantage. b. used efficiently. Some workers are without jobs, some buildings are without occupants, some fields are without crops. Comparative advantage is not the same as absolute advantage, which is when a country can produce more of a good. The production of both goods rises. Suppose it begins at point D, producing 300 snowboards per month and no skis. Direct link to Al's post 1. Plant 3 would be the last plant converted to ski production. 2.2 The Production Possibilities Frontier and Social Choices Suppose it considers moving from point B to point C. . Why production possibility curve slopes downward - YouTube Suppose a society desires two products, healthcare and education. At point A, Alpine Sports produces 350 pairs of skis per month and no snowboards. It can produce skis and snowboards simultaneously as well. PPF is more likely to be a downward-sloping curve that is bowed outward than a downward-sloping straight line because most resources are NOT: relatively cheap at low levels of output. This spending took a variety of forms. The curve is a downward-sloping straight line, indicating that there is a linear, negative relationship between the production of the two goods. Would you be able to consume what you consume now? Now consider the other end, at the lower right, of the production possibilities frontier. At point A, all available resources (i.e. Considering the situation in Figure 1 (shown again below), suppose we have only two types of resources: doctors and teachers. Production Possibilities Frontier - saylordotorg.github.io 1. As discussed in class, what fundamental question - Chegg Thus, all choices along a given PPF like B, C, and D display productive efficiency, but R does not. The production possibilities curve shown suggests an economy that can produce two goods, food and clothing. Figure 2.8 Idle Factors and Production shows an economy that can produce food and clothing. But it would not have any resources to produce education. In other words production of one good can be increased only after sacrificing some quantity of other good. The downward slope of the production possibilities curve is an implication of scarcity. Because the PPF is downward sloping from left to right, the only way society can obtain more education is by giving up some healthcare. View Answer. 18. We shall consider two goods and services: national security and a category we shall call all other goods and services. This second category includes the entire range of goods and services the economy can produce, aside from national defense and security. If the firm were to produce 100 snowboards at Plant 3, ski production would fall by 50 pairs per month (recall that the opportunity cost per snowboard at Plant 3 is half a pair of skis). The production possibilities frontier can illustrate two kinds of efficiency: productive efficiency and allocative efficiency. In either case, production within the production possibilities curve implies the economy could improve its performance. If Brazil devoted all of its resources to producing wheat, it would be producing at point A. Suppose Alpine Sports operates the three plants we examined in Figure 2.4 Production Possibilities at Three Plants. Suppose it considers moving from point B to point C. What would be the opportunity cost for the additional education? Watch this video to see another explanation as to why the PPF is curved. However, it does not have enough resources to produce outside the PPF. Over time, a growing economy will tend to shift the PPF outwards. The increase in spending on security, to SA units of security per period, has an opportunity cost of reduced production of all other goods and services. The production possibilities frontier is downward sloping: producing more of one good requires producing less of others. Production on the production possibilities curve ABCD requires that factors of production be transferred according to comparative advantage. Lets dig into this. 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. A budget constraint shows the different combinations of goods and services a consumer can purchase with their fixed budget. In our simple example above, there were two different resources: doctors and teachers, and each resource is better at one job than at the other. Why is a production possibilities frontier typically drawn as a curve, rather than a straight line? The bowed-out curve of Figure 2.5 The Combined Production Possibilities Curve for Alpine Sports becomes smoother as we include more production facilities. That is the tradeoff society faces. The opportunity cost of skis at Plant 2 is 1 snowboard per pair of skis. PDF Microeconomics 12th Edition Arnold Test Bank What is productive efficiency? 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. Thus, the production possibilities curve not only shows what can be produced; it provides insight into how goods and services should be produced. What could be wrong with an upward slopping PPF? We see in Figure 2.5 The Combined Production Possibilities Curve for Alpine Sports that, beginning at point A and producing only skis, Alpine Sports experiences higher and higher opportunity costs as it produces more snowboards. Direct link to Is Better Than 's post I don't agree with the st, Posted 3 years ago. Of course, an economy cannot really produce security; it can only attempt to provide it. Direct link to Louis Lepper's post I don't get the answer to, Posted 3 years ago. This curve depicts an entire economy that produces only skis and snowboards. An economy cannot operate on its production possibilities curve unless it has full employment. Society can choose any combination of the two goods on or inside the PPF. People work and use the income they earn to buyperhaps importgoods and services from people who have a comparative advantage in doing other things. Conversely, the opportunity cost of sugar cane is lower in Brazil. In that case, it produces no snowboards. The U.S. has comparative advantage in wheat and Brazil has comparative advantage in sugar cane. However, economics can point out that some choices are unambiguously better than others. So it makes sense for teachers to be reallocated from healthcare to education. The negative slope of the production possibilities curve reflects the scarcity of the plants capital and labor. Just as individuals cannot have everything they want and must instead make choices, society as a whole cannot haveeverything it might want, either. The Great Depression was a costly experience indeed. Between points A and B, for example, the slope equals 2 pairs of skis/snowboard (equals 100 pairs of skis/50 snowboards). Its land is devoted largely to nonagricultural use. In the wake of the 9/11 attacks in 2001, nations throughout the world increased their spending for national security. Plants 2 and 3, if devoted exclusively to ski production, can produce 100 and 50 pairs of skis per month, respectively. Suppose the first plant, Plant 1, can produce 200 pairs of skis per month when it produces only skis. Direct link to Martin's post What is a budget constrai, Posted 3 years ago. . The production of a good has an opportunity cost. The specific choice along a production possibilities frontier that reflects the mix of goods society prefers is the choice with allocative efficiency. These intercepts tell us the maximum number of pairs of skis each plant can produce. OpenStax is part of Rice University, which is a 501(c)(3) nonprofit. We can use the production possibilities model to examine choices in the production of goods and services. The opportunity cost of each of the first 100 snowboards equals half a pair of skis; each of the next 100 snowboards has an opportunity cost of 1 pair of skis, and each of the last 100 snowboards has an opportunity cost of 2 pairs of skis. 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. If resources are given and utilized in the most efficient way, then an economy can give up some good to get more good. Conversely, the opportunity cost of sugar cane is lower in Brazil. If Alpine Sports selects point C in Figure 2.9 Efficient Versus Inefficient Production, for example, it will assign Plant 1 exclusively to ski production and Plants 2 and 3 exclusively to snowboard production. She also modified the first plant so that it could produce both snowboards and skis. Because the PPF is downward sloping from left to right, the only way society can obtain more education is by giving up some healthcare. Suppose it considers moving from point B to point C. What would the opportunity cost be for the additional education? In the summer of 1929, however, things started going wrong. Producing a snowboard in Plant 3 requires giving up just half a pair of skis. Think about what life would be like without specialization. Combination A involves devoting the plant entirely to ski production; combination C means shifting all of the plants resources to snowboard production; combination B involves the production of both goods. For example, point R is productively inefficient because it is possible at choice C to have more of both goods: education on the horizontal axis is higher at point C than point R (E2 is greater than E1), and healthcare on the vertical axis is also higher at point C than point R (H2 is great than H1). 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. Chapter 2: Downward Slopping PPF and Scarcity - YouTube This production possibilities frontier shows a tradeoff between devoting social resources to healthcare and devoting them to education. Thats the trade-off this society faces. This opportunity cost equals the absolute value of the slope of the production possibilities curve. Say the doctors are practicing medicine and the teachers are helping out as best they can. When countries engage in trade, they specialize in the production of the goods that they have a comparative advantage in, and trade part of that production for goods they do not have a comparative advantage in. Between 1929 and 1942, the economy produced 25% fewer goods and services than it would have if its resources had been fully employed. Conversely, the U.S. can produce large amounts of wheat per acre, but not much sugar cane. However, improvements in productive efficiency take time to discover and implement, and economic growth happens only gradually. Allocative efficiency means that the particular mix of goods being producedthat is, the specific choice along the production possibilities frontierrepresents the allocation that society most desires. Figure 2.4 illustrates these ideas using a production possibilities frontier between healthcare and education. That will require shifting one of its plants out of ski production. Created by Sal Khan. 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 other words, the products are limited because the resources are limited. The slopes of the production possibilities curves for each plant differ. The bowed-out production possibilities curve for Alpine Sports illustrates the law of increasing opportunity cost. 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). Panel (a) of Figure 2.6 Production Possibilities for the Economy shows the combined curve for the expanded firm, constructed as we did in Figure 2.5 The Combined Production Possibilities Curve for Alpine Sports. .How would you define economic growth in terms of this model? I don't agree with the statement that allocative efficiency must imply productive efficiency. In terms of the production possibilities curve in Figure 2.7 Spending More for Security, the choice to produce more security and less of other goods and services means a movement from A to B. Imagine that society starts at choice D, which is devoting nearly all resources to education and very few to healthcare, and moves to point F, which is devoting all spending to education and none to healthcare. The slope of the PPF at a given point is the amount of good 'A' that would have to be sacrificed to get an additional unit of good 'B" That is the opportunity cost of getting an extra unit of good . To see this relationship more clearly, examine Figure 2.3 The Slope of a Production Possibilities Curve. To construct a combined production possibilities curve for all three plants, we can begin by asking how many pairs of skis Alpine Sports could produce if it were producing only skis. 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). Understand the difference between comparative advantage and . Why is allocative inefficiency also wasteful? Did you have an idea for improving this content? In drawing production possibilities curves for the economy, we shall generally assume they are smooth and bowed out, as in Panel (b). Suppose an economy fails to put all its factors of production to work. Just as individuals cannot have everything they want and must instead make choices, society as a whole cannot have everything it might want, either. By contrast, the slope of a PPF is the cost to society of producing one good or service relative to the other good or service. However, any choice inside the production possibilities frontier is productively inefficient and wasteful because it is possible to produce more of one good, the other good, or some combination of both goods. The combined production possibilities curve for the firms three plants is shown in Figure 2.5 The Combined Production Possibilities Curve for Alpine Sports. Suppose it considers moving from point B to point C. What would the opportunity cost be for the additional education? At A all resources go to healthcare and at B, most go to healthcare. It is hard to imagine that most of us could even survive in such a setting. 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 . Now imagine that some of these resources are diverted from healthcare to education, so that the economy is at point B instead of point A. Check with . Theres another way to think about this. They continued to fall for several years. Society can choose any combination of the two goods on or inside the PPF. The result is the bowed-in curve ABCD. Direct link to Andrea Burgio's post I dont know if i'm missin, Posted 2 years ago. (i) PP curve slopes down. This book uses the Should the government promote the product or what? Explain why societies cannot make a choice above their production possibilities frontier and should not make a choice below it. In our example, all three plants are equally good at snowboard production. This is a result of transferring resources from the production of one good to another according to comparative advantage. For example, children are seeing a doctor every day, whether theyre sick or not, but not attending school. The PPF is downward sloping because it depicts the trade-off between two products. all the doctors and all the teachers) are devoted to providinghealth care and none isleft for education. There are no specific numbers because we do not know the exact amount of resources this imaginary economy has, nor do we know how many resources it takes to produce healthcare and how many resources it takes to produce education. The second plant, while smaller than the first, was designed to produce snowboards as well as skis. 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 short, the slope of the PPF from point F to D would be steep, and the opportunity cost of education in terms of healthcare would be high. . 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. In this way, the law of increasing opportunity cost produces the outward-bending shape of the production possibilities frontier. Expanding snowboard production to 51 snowboards per month from 50 snowboards per month requires a reduction in ski production to 98 pairs of skis per month from 100 pairs. What does the slope of the PPF measure? The absolute value of the slope of a production possibilities curve measures the opportunity cost of an additional unit of the good on the horizontal axis measured in terms of the quantity of the good on the vertical axis that must be forgone. Why the PPF is downward slopping? - Answers (I mean, we should move point A higher and don't change point F.) The question about task 1 in Self-Check questions, "Output mixes that had more healthcare (and less education) would have a steeper ray, while those with more education (and less healthcare) would have a flatter ray.". Solution The production possibility curve is downward sloping from left to right because more of good X can be produced only with less production of good Y, when the given resources are assumed to be fully and efficiently utilised, using the given technology. Notice also that this curve has no numbers. In this way, the law of diminishing returns produces the outward-bending shape of the production possibilities frontier. Figure 1 (shown again). A production possibilities frontier showing health care and education. If however it had devoted all of its resources to producing sugar cane instead, it would be producing a much larger amount than the U.S., at point B. If every trade-off were the same, it would create a straight line. As it does, the production possibilities frontier for a society will tend to shift outward and society will be able to afford more of all goods. You must produce everything you consume; you obtain nothing from anyone else. However, we drew the production possibilities frontier for healthcare and education as a curved line. What type of resources are going to move to producing education? When can PPC be a straight line? Figure 2. The curvature of the PPF is likely to differ by country, which results in different countries having comparative advantage in different goods. Want to create or adapt books like this? 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. Both images have y-axes labeled Sugar Cane and x-axes labeled Wheat. In image (a), Brazils Sugar Cane production is nearly double the production of its wheat. Draw the production possibilities curve for Plant R. On a separate graph, draw the production possibilities curve for Plant S. Which plant has a comparative advantage in calculators? Direct link to Joshua's post The PPF graph is major si, Posted 2 years ago. In applying the model, we assume that the economy can produce two goods, and we assume that technology and the factors of production available to the economy remain unchanged. The reverse is also true: the U.S. has a lower opportunity cost of producing wheat than Brazil. So it is constant because the slope is constantly the same. In such a case, more of one good can be produced only by taking resources away from the production of another good. Also, the simplified PPF does not show demand. Suppose it considers moving from point B to point C. What would be the opportunity cost for the additional education? What happen if society wants less products than what are on the productive efficiency point? 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. The law of increasing opportunity cost tells us that, as the economy moves along the production possibilities curve in the direction of more of one good, its opportunity cost will increase. If there is always a three-for-one tradeoff between goods X and Y, then the PPF between X and Y is a. a downward-sloping curve that is bowed outward. Direct link to anutkalaund's post I don't understand: if we, Posted 5 days ago. 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. The production possibilities curve illustrates the choices involved in this dilemma. The law also applies as the firm shifts from snowboards to skis. 2. it, Posted 2 years ago. Why is the PPF downward sloping? And when they move, the society doesnt lose much healthcare, because the teachers werent very good at that. Because of this, the magnitude of the slope of the PPF increases, meaning the slope gets steeper, as we move down and to the right along the curve. The budget constraints that we presented earlier in this chapter, showing individual choices about what quantities of goods to consume, were all straight lines. Conversely, as we add more resources to healthcare, moving from bottom to top on the vertical axis, the original declines in opportunity cost are fairly large, but again gradually diminish. An economy that fails to make full and efficient use of its factors of production will operate inside its production possibilities curve. It suggests that to obtain efficiency in production, factors of production should be allocated on the basis of comparative advantage.

A production possibilities frontiershows the possiblecombinations of goods and services that a society can produce with its limited resources. Explain the concept of the production possibilities curve and understand the implications of its downward slope and bowed-out shape. This video explains why PPC slopes downward with a simple examplePrevious concept - production possibility curve(link - https://youtu.be/gaZij24SJvk )Related. Use the production possibilities model to distinguish between full employment and situations of idle factors of production and between efficient and inefficient production. In the production possibilities framework, economic growth is depicted by the PPF In effect, the production possibilities frontier plays the same role for society as the budget constraint plays for Alphonso. At point A, all available resources are devoted to healthcare and no resources are left for education. https://openstax.org/books/principles-economics-3e/pages/1-introduction, https://openstax.org/books/principles-economics-3e/pages/2-2-the-production-possibilities-frontier-and-social-choices, Creative Commons Attribution 4.0 International License, Interpret production possibilities frontier graphs, Contrast a budget constraint and a production possibilities frontier, Explain the relationship between a production possibilities frontier and the law of diminishing returns, Contrast productive efficiency and allocative efficiency. With trade, manufacturers produce goods where the opportunity cost is lowest, so total production increases, benefiting both trading parties. Given the labor and the capital available at both plants, it can produce the combinations of the two goods at the two plants shown. The study of economics does not presume to tell a society what choice it should make along its production possibilities frontier. Figure 2.9 Efficient Versus Inefficient Production. Production and employment fell. 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. The 100 Best Restaurants in NYC - The New York Times Output mixes that had more healthcare (and less education) would have a steeper ray, while those with more education (and less healthcare) would have a flatter ray. d. an upward-sloping straight line.
