Suppose society has chosen to operate at point B, and it is considering producing more education. 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. 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. Opportunity cost. 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. .How would you define a production point that represent efficient versus inefficient use of the resources? However, economics can point out that some choices are unambiguously better than others. While every society must choose how much of each good it should produce, it does not need to produce every single good it consumes. The opportunity cost of an additional snowboard at each plant equals the absolute values of these slopes. The PPF is downward sloping because it depicts the trade-off between two products. Some workers are without jobs, some buildings are without occupants, some fields are without crops. Points on the production possibilities curve thus satisfy two conditions: the economy is making full use of its factors of production, and it is making efficient use of its factors of production. 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. 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. Point R on the graph represents the good that drops in quantity as a result of greater efficiency in producing other goods. That is the tradeoff society faces. The production possibilities curves for the two plants are shown, along with the combined curve for both plants. The study of economics does not presume to tell a society what choice it. The reason for the shape of the Production Possibilities Curve (PPC) is something called the law of increasing opportunity costs. hover over link. I don't agree with the statement that allocative efficiency must imply productive efficiency. We often think of the loss of jobs in terms of the workers; they have lost a chance to work and to earn income. However, putting those marginal dollars into education, which is completely without resources at point A, can produce relatively large gains. It has two plants, Plant R and Plant S, at which it can produce these goods. In this way, the law of diminishing returns produces the outward-bending shape of the production possibilities frontier. 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. (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.". Why is a production possibilities frontier typically drawn as a curve, rather than a straight line? It suggests that to obtain efficiency in production, factors of production should be allocated on the basis of comparative advantage. In Plant 2, she must give up one pair of skis to gain one more snowboard. In this way, the law of diminishing returns produces the outward-bending shape of the production possibilities frontier. The shape of the PPF is typically curved outward, rather than straight. 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. 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. In contrast, the PPF has a curved shape because of the law of the diminishing returns. 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. In a market-oriented economy with a democratic government, the choice will involve a mixture of decisions by individuals, firms, and government. We recommend using a In that case, it produces no snowboards. Suppose that, as before, Alpine Sports has been producing only skis. Production Possibility Frontier for the U.S. and Brazil. 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. Suppose Alpine Sports operates the three plants we examined in Figure 2.4 Production Possibilities at Three Plants. Much of the land in the United States has a comparative advantage in agricultural production and is devoted to that activity. 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. Use the production possibilities model to distinguish between full employment and situations of idle factors of production and between efficient and inefficient production. Opportunity Cost Increases Along the PPF You may have noticed that the PPF was drawn such that it is bowed out from the origin. 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. Suppose it considers moving from point B to point C. What would be the opportunity cost for the additional education? Clearly, Brazil has a lower opportunity cost of producing sugar cane (in terms of wheat) than the U.S. In effect, the production possibilities frontier plays the same role for society as the budget constraint plays for Charlie. As it does, the production possibilities frontier for a society will shift outward and society will be able to afford more of all goods. Producing more skis requires shifting resources out of snowboard production and thus producing fewer snowboards. If Brazil devoted all of its resources to producing wheat, it would be producing at point A. Just as individuals cannot have everything they want and must instead make choices, society as a whole cannot have everything it might want, either. 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. 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. We would say that Plant 1 has a comparative advantage in ski production. There, 50 pairs of skis could be produced per month at a cost of 100 snowboards, or an opportunity cost of 2 snowboards per pair of skis. We illustrate this by the PPFs of the two countries in Figure 2.5. In the self-check questions, it is stated in the solution that both in consumers budget constraint and societys production possibilities frontier, the graph shows the opportunity cost graphically as the slope of the constraint (budget or PPF). Just as individuals cannot have everything they want and must instead make choices, society as a whole cannot haveeverything it might want, either. The economy had moved well within its production possibilities curve. The slope of the PPF gives the opportunity cost of producing an additional unit of wheat. Because the PPF is downward sloping from left to right, the only way society can obtain more education is by giving up some healthcare.
