Thus, the production possibilities curve not only shows what can be produced; it provides insight into how goods and services should be produced. That is the tradeoff society faces. Similarly, the society could allocate all of its resources to producing education, and none to producing healthcare, as shown at point F. Alternatively, the society could choose to produce any combination of health care and education shown on the production possibilities frontier. 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 law of diminishing returns holds that as increments of additional resources are devoted to producing something, the marginal increase in output will become smaller and smaller. What does the slope of the PPF measure? 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. However, we drew the production possibilities frontier for healthcare and education as a curved line. Society can choose any combination of the two goods on or inside the PPF. Society can choose any combination of the two goods on or inside the PPF. An economys factors of production are scarce; they cannot produce an unlimited quantity of goods and services. This time, however, imagine that Alpine Sports switches plants from skis to snowboards in numerical order: Plant 1 first, Plant 2 second, and then Plant 3. The slope of Plant 1s production possibilities curve measures the rate at which Alpine Sports must give up ski production to produce additional snowboards. Given the labor and the capital available at both plants, it can produce the combinations of the two goods at the two plants shown. d. used to produce consumption goods. 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. That is because the resources transferred from the production of other goods and services to the production of security had a greater and greater comparative advantage in producing things other than security. Producing 100 snowboards at Plant 2 would leave Alpine Sports producing 200 snowboards and 200 pairs of skis per month, at point C. If the firm were to switch entirely to snowboard production, Plant 1 would be the last to switch because the cost of each snowboard there is 2 pairs of skis. As a result of a failure to achieve full employment, the economy operates at a point such as B, producing FB units of food and CB units of clothing per period. Two years later she added a third plant in another town. Just as individuals cannot have everything they want and must instead make choices, society as a whole cannot haveeverything it might want, either. It illustrates the production possibilities model. Its land is devoted largely to nonagricultural use. Productive efficiency means it is impossible to produce more of one good without decreasing the quantity that is produced of another good. We shall examine the significance of the bowed-out shape of the curve in the next section. 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. If you use it this way . The production possibilities frontier can illustrate two kinds of efficiency: productive efficiency and allocative efficiency. The steeper the curve, the greater the opportunity cost of an additional snowboard. the PPF). That will require shifting one of its plants out of ski production. Now suppose the firm decides to produce 100 snowboards. We can use the production possibilities model to examine choices in the production of goods and services. This situation would be extreme and even ridiculous. If there are idle or inefficiently allocated factors of production, the economy will operate inside the production possibilities curve. Inefficient production implies that the economy could be producing more goods without using any additional labor, capital, or natural resources. The particular mix of goods and services being producedthat is, the specific combination of healthcare and education chosen along the production possibilities frontiercan be shown as a ray (line) from the origin to a specific point on the PPF. In this example, production moves to point B, where the economy produces less food (FB) and less clothing (CB) than at point 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 NOT: relatively cheap at low levels of output. Where does the PPF come from? When devoted solely to snowboards, it produces 100 snowboards per month. Clearly, Brazil has a lower opportunity cost of producing sugar cane (in terms of wheat) than the U.S. No matter how many of each good or service a consumer buys, the prices stay the same. Thus, all choices along a given PPF like B, C, and D display productive efficiency, but R does not. As time passes, the production possibilities frontier shifts outward due to the accumulation of inputs and technological progress. hover over link. Plant 3, though, is the least efficient of the three in ski production. Because at any given moment, society has limited resources, it follows that theres a limit to the quantities of goods and services it can produce. Say the doctors are practicing medicine and the teachers are helping out as best they can. If all the factors of production that are available for use under current market conditions are being utilized, the economy has achieved full employment. What could be wrong with an upward slopping PPF? The U.S. economy looked very healthy in the beginning of 1929. This observation is based on the concept of efficiency. Just as individuals cannot have everything they want and must instead make choices, society as a whole cannot have everything it might want, either. d. an upward-sloping straight line. Suppose Alpine Sports operates the three plants we examined in Figure 2.4 Production Possibilities at Three Plants. In that case, it produces no snowboards. The firm then starts producing snowboards. 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. 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. Our mission is to improve educational access and learning for everyone. The Production Possibilities Frontier and Social Choices. One can easily see this with a simple observation of the extreme production points in the PPFs of the two countries. Figure 2.9 Efficient Versus Inefficient Production. Production possibilities represent the alternative choices of goods that the economy can produce. Suppose an economy fails to put all its factors of production to work. There are more similarities than differences between individual choice and social choice. 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. Why does the PPF is a downward sloping curve? The opportunity cost would be the health care that society has to give up. If all resources in the economy where allocated to produci. Could a nation be producing in a way that is allocatively efficient, but productively inefficient? We assume that the factors of production and technology available to each of the plants operated by Alpine Sports are unchanged. Society can choose any combination of the two goods on or inside the PPF. Conversely, the U.S. can produce a lot of wheat per acre, but not much sugar cane. If it is using the same quantities of factors of production but is operating inside its production possibilities curve, it is engaging in inefficient production. We can think of each of Ms. Ryders three plants as a miniature economy and analyze them using the production possibilities model. When an economy is operating on its production possibilities curve, we say that it is engaging in efficient production. As you read this section, focus on the similarities. Production Possibility Frontier Questions and Answers Economists conclude that it is better to be on the production possibilities curve than inside it. Watch this video to see another explanation as to why the PPF is curved. Now suppose Alpine Sports is fully employing its factors of production. The opportunity cost of the first 200 pairs of skis is just 100 snowboards at Plant 1, a movement from point D to point C, or 0.5 snowboards per pair of skis. Suppose it considers moving from point B to point C. What would the opportunity cost be for the additional education? Use the production possibilities model to distinguish between full employment and situations of idle factors of production and between efficient and inefficient production. A PPF w/Constant Opportunity Cost is a linear line, meaning the line is straight (not curved), and To be linear means the change between any two points anywhere on the line will be consistent. Bowed when -factors of production are heterogeneous (Some laborers are better at one thing than the other) OR Production Possibilities Frontier - saylordotorg.github.io The OpenStax name, OpenStax logo, OpenStax book covers, OpenStax CNX name, and OpenStax CNX logo There are more similarities than differences, so for now focus on the similarities. Imagine that you are suddenly completely cut off from the rest of the economy. We will generally draw production possibilities curves for the economy as smooth, bowed-out curves, like the one in Panel (b). 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 PPF graph is major simplification of the real world. Because the PPF is downward sloping from left to right, the only way society can obtain more education is by giving up some healthcare. It can produce skis and snowboards simultaneously as well. Further, the economy must make full use of its factors of production if it is to produce the goods and services it is capable of producing. The decision to devote more resources to security and less to other goods and services represents the choice we discussed in the chapter introduction. Theres another way to think about this. If Brazil devoted all of its resources to producing wheat, it would be producing at point A. Clearly, the transfer of resources to the effort to enhance national security reduces the quantity of other goods and services that can be produced. we learned that every society faces the problem of scarcity, where limited resources conflict with unlimited needs and wants. This production possibilities frontier shows a tradeoff between devoting social resources to healthcare and devoting them to education. The downward sloping nature of the PPC is due to the law of increasing opportunity cost. By 1933, more than 25% of the nations workers had lost their jobs. The next 100 pairs of skis would be produced at Plant 2, where snowboard production would fall by 100 snowboards per month. 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. (i) Why is PP curve downward sloping from left to right? (D 2006C) (ii Plant 3s comparative advantage in snowboard production makes a crucial point about the nature of comparative advantage. The production possibilities model does not tell us where on the curve a particular economy will operate. The PPF is a simple economic model (usually demonstrated as a graph) that helps explain the potential output in an economy given the available resources. These days, when you open a PPF account, the balance is available online. A concave curve is one that bends outward from the origin. The reason for the shape of the Production Possibilities Curve (PPC) is something called the law of increasing opportunity costs. Total production can increase if countries specialize in the goods they have comparative advantage in and trade some of their production for the remaining goods. Suppose further that all three plants are devoted exclusively to ski production; the firm operates at A. Whether or not we have specific numbers, conceptually we can measure the opportunity cost of additional education as society moves from point B to point C on the PPF. However, the opportunity cost lost to health will be fairly large, and thus the slope of the PPF between D and F is steep, showing a large drop in health for only a small gain in education. Where will it produce them? Wouldn't allocative efficiency occur at the origin? However, it does not have enough resources to produce outside the PPF. Countries tend to have different opportunity costs of producing a specific good, either because of different climates, geography, technology or skills. Economists often use models such as the production possibilities model with graphs that show the general shapes of curves but that do not include specific numbers.
