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. As we saw earlier, the curvature of a country’s PPF gives us information about the tradeoff between devoting resources to producing one good versus another. The shape of the PPF is typically curved outward, rather than straight. To understand why the PPF is curved, start by considering point A at the top left-hand side of the PPF. In Figure 1, healthcare is shown on the vertical axis and education is shown on the horizontal axis. Lesson summary: the production possibilities frontier. The curvature of the PPF is likely to differ by country, which results in different countries having comparative advantage in different goods. This pattern is common enough that it has been given a name: the law of diminishing returns, which holds that as additional increments of resources are added to a certain purpose, the marginal benefit from those additional increments will decline. B)the exchange of one good or service for another. 04 Therefore, international trade should lead to an increase in economic efficiency and economic growth. What is productive efficiency? 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. endowment points. What are the similarities between a consumer’s budget constraint and society’s production possibilities frontier, not just graphically but analytically? That is the tradeoff society faces. c) unattainable and efficient. With trade, goods are produced where the opportunity cost is lowest, so total production increases, benefiting both trading parties. This situation is illustrated by the production possibilities frontier in Figure 1. On the other hand, if a large number of resources are already committed to education, then committing additional resources will bring relatively smaller gains. 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. Production possibilities frontier is also known as the production possibilities curve (PPC). 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. (Points: 1) simplify reality in order to highlight what really matters attempt to duplicate reality in all its complexity ignore the facts, and instead try to determine what the facts should be do all of the above 2. 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. 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.

However, economics can point out that some choices are unambiguously better than others. In contrast, points outside the frontier are not attainable given the resources and technology present. This would make the PPF steeper, corresponding to an increase in the opportunity cost of education, since resources devoted to education would now mean forgoing a greater quantity of healthcare. 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. 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. Complete the following: a. Graph a PPC Curve. The gains to education from adding these last few resources to education are very small. Every economy faces two situations in which it may be able to expand consumption of all goods.

Become a Study.com member to unlock this People are having cosmetic surgery on every part of their bodies, but no high school or college education exists. 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. A point beneath the curve indicates inefficiency, and a point beyond the curve indicates impossibility. In effect, the production possibilities frontier plays the same role for society as the budget constraint plays for Alphonso. 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. Practice: Interpreting graphs of the production possibilities curve (PPC) How to determine what a society desires can be a controversial question, and is usually discussed in political science, sociology, and philosophy classes as well as in economics. But it cannot produce at points outside the frontier. The production possibilities curve is also called the PPF or the production possibilities frontier. The Impacts of Government Borrowing, Introduction to the Impacts of Government Borrowing, 31.1 How Government Borrowing Affects Investment and the Trade Balance, 31.2 Fiscal Policy, Investment, and Economic Growth, 31.3 How Government Borrowing Affects Private Saving, Chapter 32. Over time, a growing economy will tend to shift the PPF outwards. 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). If this were a real world example, that data would be available. b. the citizens of the country have a greater desire to consume goods and services than do the citizens of other countries. Sciences, Culinary Arts and Personal Because society has limited resources (e.g., labor, land, capital, raw materials) at any point in time, there is a limit to the quantities of goods and services it can produce. This observation is based on the concept of efficiency. When you think of improvements in healthcare, you can think of longer life expectancies, lower levels of infant mortality, and fewer outbreaks of disease. point outside the production possibility frontier are attainable but inefficient. 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. Due to its climatic conditions, Brazil can produce a lot of sugar cane per acre but not much wheat. While every society must choose how much of each good it should produce, it does not need to produce every single good it consumes. This quiz has around twelve questions of the same topic; choose the correct answer. For example, children are seeing a doctor every day, whether they are sick or not, but not attending school. Only one of the productively efficient choices will be the allocatively efficient choice for society as a whole. A point or combination that is on the production possibilities frontier is. Question: At Various Points Along The Production Possibilities Frontier, A. The first difference between a budget constraint and a production possibilities frontier is that the PPF, because it’s looking at societal choice, is going to have much larger numbers on the axes than those on an individual’s budget constraint. Principles of Economics by Rice University is licensed under a Creative Commons Attribution 4.0 International License, except where otherwise noted. But improvements in productive efficiency take time to discover and implement, and economic growth happens only gradually. Poverty and Economic Inequality, Introduction to Poverty and Economic Inequality, 14.4 Income Inequality: Measurement and Causes, 14.5 Government Policies to Reduce Income Inequality, Chapter 15. It is easiest to understand the PPF by visualizing it in just two dimensions. It also suffered many human casualties, both soldiers and civilians. In our example, Brazil has a comparative advantage in sugar cane and the U.S. has a comparative advantage in wheat. All choices along a production possibilities frontier display productive efficiency; that is, it is impossible to use society’s resources to produce more of one good without decreasing production of the other good. D)opportunity cost. 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. 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). true or false. Production points inside the curve show an economy is not producing at its comparative advantage. The Production Possibilities Frontier . Countries tend to have different opportunity costs of producing a specific good, either because of different climates, geography, technology or skills. At the individual and firm level, the market economy coordinates a process in which firms seek to produce goods and services in the quantity, quality, and price that people want. However, putting those marginal dollars into education, which is completely without resources at point A, can produce relatively large gains. The reverse is also true; the U.S. has a lower opportunity cost of producing wheat than Brazil. Allocative efficiency? If on the one hand, very few resources are currently committed to education, then an increase in resources used can bring relatively large gains.
