Plants 2 and 3, if devoted exclusively to ski production, can produce 100 and 50 pairs of skis per month, respectively. Productive efficiency means that, given the available inputs and technology, it is impossible to produce more of one good without decreasing the quantity that is produced of another good. For society, there are many scarce resources. Lesson summary: Opportunity cost and the PPC - Khan Academy The related concept of marginal cost is the cost of producing one extra unit of something. Suppose a society desires two products, healthcare and education. At D most resources go to education, and at F, all go to education. In Plant 2, she must give up one pair of skis to gain one more snowboard. In this way, the law of increasing opportunity cost produces the outward-bending shape of the production possibilities frontier. a. better suited for the production of some goods than others. Instead, it lays out the possibilities facing the economy. The curve shown combines the production possibilities curves for each plant. The production possibilities curve illustrates the choices involved in this dilemma. Notice the curve still has a bowed-out shape; it still has a negative slope. citation tool such as, Authors: Steven A. Greenlaw, David Shapiro, Daniel MacDonald. Society can choose any combination of the two goods on or inside the PPF. Inefficient production implies that the economy could be producing more goods without using any additional labor, capital, or natural resources. 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. 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. 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. Wed love your input. Producing more snowboards requires shifting resources out of ski production and thus producing fewer skis. In drawing the production possibilities curve, we shall assume that the economy can produce only two goods and that the quantities of factors of production and the technology available to the economy are fixed. 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. But it does not have enough resources to produce outside the PPF. 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. Draw and explain what would happen to this market if an . Explain the concept of the production possibilities curve and understand the implications of its downward slope and bowed-out shape. The PPF looks a bit like a budget constraint. The slope of the linear production possibilities curve in Figure 2.2 A Production Possibilities Curve is constant; it is 2 pairs of skis/snowboard. Suppose it considers moving from point B to point C. . Most important, the production possibilities frontier clearly shows the tradeoff between healthcare and education. Use the production possibilities model to distinguish between full employment and situations of idle factors of production and between efficient and inefficient production. In particular, its slope gives the opportunity cost of producing one more unit of the good in the x-axis in terms of the other good (in the y-axis). Producing 1 additional snowboard at point B requires giving up 2 pairs of skis. 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. Figure 2.4 Production Possibilities at Three Plants shows production possibilities curves for each of the firms three plants. This spending took a variety of forms. On the other hand, if a large number of resources are already committed to education, then committing additional resources will bring relatively smaller gains. The exhibit gives the slopes of the production possibilities curves for each of the firms three plants. People are having cosmetic surgery on every part of their bodies, but no high school or college education exists. It need not imply that a particular plant is especially good at an activity. The law of increasing opportunity cost holds that as an economy moves along its production possibilities curve in the direction of producing more of a particular good, the opportunity cost of additional units of that good will increase. A production possibilities frontier defines the set of choices society faces for the combinations of goods and services it can produce given the resources available.
