why is the ppf downward sloping

That's the trade-off this society faces. This book uses the As we combine the production possibilities curves for more and more units, the curve becomes smoother. On the other hand, if a large number of resources are already committed to education, then committing additional resources will bring relatively smaller gains. Due to its climatic conditions, Brazil can produce quite a bit of sugar cane per acre but not much wheat. In other words, each resource is not worth the same at producing different products. Direct link to Sage Taki's post In the self-check questio, Posted 2 years ago. As we saw earlier, the curvature of a countrys PPF gives us information about the tradeoff between devoting resources to producing one good versus another. The downward slope of the production possibilities curve is an implication of scarcity. 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. 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 opportunity cost would be the health care that society has to give up. Say the doctors are practicing medicine and the teachers are helping out as best they can. Were now readyto address the differences between societys PPF and an individuals budget constraint. the PPF). For example, children are seeing a doctor every day, whether they are sick or not, but not attending school. Figure 2.9 Efficient Versus Inefficient Production. The opportunity cost would be the healthcare society has to give up. 2.2 The Production Possibilities Curve - Principles of Economics Figure 2.6 Production Possibilities for the Economy. 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. Why does the PPF bow outward and what does that imply? Increasing the availability of these goods would improve the standard of living. PPC is downward sloping because production of one item can be increased only after sacrificing some of the other good. Alpine Sports can thus produce 350 pairs of skis per month if it devotes its resources exclusively to ski production. Suppose a society desires two products, healthcare and education. 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. An economy's production possibilities boundary is given by 45 = A + 5B, where A is the quantity of good A and B is the quantity of good B. The result is the bowed-in curve ABCD. By now you might be saying, Hey, this PPF is sounding like the budget constraint. If so, read the following Clear It Up feature. Most importantly, the production possibilities frontier clearly shows the tradeoff between healthcare and education. 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. 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. There are at least two ways to read this list. The fact that the opportunity cost of additional snowboards increases as the firm produces more of them is a reflection of an important economic law. PP curve slopes down from left to right because in presence of scarcity of resources more of one good can be produced only if resources are withdrawn from production of other good. Here, an economy that can produce two categories of goods, security and all other goods and services, begins at point A on its production possibilities curve. Now imagine that some of these resources are diverted from health care to education, so that the economy is at point B instead of point A. To put this in terms of the production possibilities curve, Plant 3 has a comparative advantage in snowboard production (the good on the horizontal axis) because its production possibilities curve is the flattest of the three curves. 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. This choice is shown in Figure 1 at point A. We will see in the chapter on demand and supply how choices about what to produce are made in the marketplace. But the production possibilities model points to another loss: goods and services the economy could have produced that are not being produced. Now consider what would happen if Ms. Ryder decided to produce 1 more snowboard per month. The plant for which the opportunity cost of an additional snowboard is greatest is the plant with the steepest production possibilities curve; the plant for which the opportunity cost is lowest is the plant with the flattest production possibilities curve. Similarly, as additional resources are added to health care, moving from bottom to top on the vertical axis, the initialgains are fairly large but again gradually diminish. A concave curve is one that bends outward from the origin. Production Possibility Frontier for the U.S. and Brazil. 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. 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. And is this the case of allocative inefficiency? As we choose more of one good and less of another, we are simply spending dollars on different items, but every dollar is worth the same in purchasing any item. Points that lie inside (or below) the PPF are a . Plant 3 has a comparative advantage in snowboard production because it is the plant for which the opportunity cost of additional snowboards is lowest. At A all resources go to healthcare and at B, most go to healthcare. Suppose the first plant, Plant 1, can produce 200 pairs of skis per month when it produces only skis. Just as with Charliesbudget constraint, the opportunity cost is shown by theslope of the production possibilities frontier. The reverse is also true: the U.S. has a lower opportunity cost of producing wheat than Brazil. While even smaller than the second plant, the third was primarily designed for snowboard production but could also produce skis. An outward shift in the production possibilities frontier (PPF) indicates an expansion in the economy caused by a change in technology or an increase in resources. Suppose there is an improvement in medical technology that enables more healthcare to be provided with the same amount of resources. Had the firm based its production choices on comparative advantage, it would have switched Plant 3 to snowboards and then Plant 2, so it would have operated at point 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. While every society must choose how much of each good it should produce, it does not need to produce every single good it consumes. An Emerging Consensus: Macroeconomics for the Twenty-First Century, 33.1 The Nature and Challenge of Economic Development, 33.2 Population Growth and Economic Development, 34.1 The Theory and Practice of Socialism, 34.3 Economies in Transition: China and Russia, Appendix A.1: How to Construct and Interpret Graphs, Appendix A.2: Nonlinear Relationships and Graphs without Numbers, Appendix A.3: Using Graphs and Charts to Show Values of Variables, Appendix B: Extensions of the Aggregate Expenditures Model, Appendix B.2: The Aggregate Expenditures Model and Fiscal Policy. In this way, the law of diminishing returns produces the outward-bending shape of the production possibilities frontier. Figure 2.4 Production Possibilities at Three Plants. A production possibilities frontiershows the possiblecombinations of goods and services that a society can produce with its limited resources. d. an upward-sloping straight line. Why is the production possibilities curve bowed out in shape? False. That is the tradeoff society faces. Health care is shown on the vertical (or y) axis, and education is shown on the horizontal (or x) axis. Specialization implies that an economy is producing the goods and services in which it has a comparative advantage. 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). That would bring ski production to 300 pairs, at point B. I'm pretty sure it wasn't mentioned in previous videos in this section. 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. However, it does not have enough resources to produce outside the PPF. While every society must choose how much of each good or service it should produce, it does not need to produce every single good it consumes. In this lesson, let's assume we can produce either baseballs or puzzles. The PPF captures the concepts of scarcity, choice, and tradeoffs. 2.3 Applications of the Production Possibilities Model, 4.2 Government Intervention in Market Prices: Price Floors and Price Ceilings, 5.2 Responsiveness of Demand to Other Factors, 7.3 Indifference Curve Analysis: An Alternative Approach to Understanding Consumer Choice, 8.1 Production Choices and Costs: The Short Run, 8.2 Production Choices and Costs: The Long Run, 9.2 Output Determination in the Short Run, 11.1 Monopolistic Competition: Competition Among Many, 11.2 Oligopoly: Competition Among the Few, 11.3 Extensions of Imperfect Competition: Advertising and Price Discrimination, 14.1 Price-Setting Buyers: The Case of Monopsony, 15.1 The Role of Government in a Market Economy, 16.1 Antitrust Laws and Their Interpretation, 16.2 Antitrust and Competitiveness in a Global Economy, 16.3 Regulation: Protecting People from the Market, 18.1 Maximizing the Net Benefits of Pollution, 20.1 Growth of Real GDP and Business Cycles, 22.2 Aggregate Demand and Aggregate Supply: The Long Run and the Short Run, 22.3 Recessionary and Inflationary Gaps and Long-Run Macroeconomic Equilibrium, 23.2 Growth and the Long-Run Aggregate Supply Curve, 24.2 The Banking System and Money Creation, 25.1 The Bond and Foreign Exchange Markets, 25.2 Demand, Supply, and Equilibrium in the Money Market, 26.1 Monetary Policy in the United States, 26.2 Problems and Controversies of Monetary Policy, 26.3 Monetary Policy and the Equation of Exchange, 27.2 The Use of Fiscal Policy to Stabilize the Economy, 28.1 Determining the Level of Consumption, 28.3 Aggregate Expenditures and Aggregate Demand, 30.1 The International Sector: An Introduction, 31.2 Explaining InflationUnemployment Relationships, 31.3 Inflation and Unemployment in the Long Run, 32.1 The Great Depression and Keynesian Economics, 32.2 Keynesian Economics in the 1960s and 1970s, 32.3. Here, we have placed the number of pairs of skis produced per month on the vertical axis and the number of snowboards produced per month on the horizontal axis. Some workers are without jobs, some buildings are without occupants, some fields are without crops. c. a downward-sloping straight line. See full answer below. .How would you define a production point that represent efficient versus inefficient use of the resources? Direct link to Andrea Burgio's post I dont know if i'm missin, Posted 2 years ago. Two years later she added a third plant in another town. The PPF: Law of Increasing Opportunity Cost - St. Louis Fed The decision to devote more resources to security and less to other goods and services represents the choice we discussed in the chapter introduction. The U.S. economy looked very healthy in the beginning of 1929. then you must include on every digital page view the following attribution: Use the information below to generate a citation. Plant S has a comparative advantage in producing radios, so, if the firm goes from producing 150 calculators and no radios to producing 100 radios, it will produce them at Plant S. In the production possibilities curve for both plants, the firm would be at M, producing 100 calculators at Plant R.
