Comparative advantage and the terms of trade . In effect, the production possibilities frontier plays the same role for society as the budget constraint plays for Alphonso. Q12) In general, if a production possibilities curve is concave rather than a straight line, it shows: Decreasing opportunity cost of specializing in production. Both the budget constraint and the PPF show the constraint that each operates under. However, economics can point out that some choices are unambiguously better than others. To understand why the PPF is curved, start by considering point A at the top left-hand side of the PPF. The straight-line production possibilities curve introduced in the text Countries tend to have different opportunity costs of producing a specific good, either because of different climates, geography, technology or skills. When government spends a certain amount more on reducing crime, for example, the original gains in reducing crime could be relatively large. However, when you think of improvements in education, you can think of accomplishments like more years of school completed, fewer high-school dropouts, and higher scores on standardized tests. Explain why production possibility curve is concave? Its always drawn as a curve and not a straight line because there a cost involved in making a choice i.e when the quantity of one good produced is higher and the quantity of the other is low. 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. No. If on the one hand, very few resources are currently committed to education, then an increase in resources used can bring relatively large gains. The PPF is called a frontier or a boundary line because any point on the curve represents full employment of resources. Environmental Protection and Negative Externalities, Introduction to Environmental Protection and Negative Externalities, 12.4 The Benefits and Costs of U.S. Environmental Laws, 12.6 The Tradeoff between Economic Output and Environmental Protection, Chapter 13. Society can choose any combination of the two goods on or inside the PPF. But additional increases typically cause relatively smaller reductions in crime, and paying for enough police and security to reduce crime to nothing at all would be tremendously expensive. In our example, Brazil has a comparative advantage in sugar cane and the U.S. has a comparative advantage in wheat. The PPF curve can be for a single company or producer, or for the economy as a whole. 1.3 How Economists Use Theories and Models to Understand Economic Issues, 1.4 How Economies Can Be Organized: An Overview of Economic Systems, Introduction to Choice in a World of Scarcity, 2.1 How Individuals Make Choices Based on Their Budget Constraint, 2.2 The Production Possibilities Frontier and Social Choices, 2.3 Confronting Objections to the Economic Approach, 3.1 Demand, Supply, and Equilibrium in Markets for Goods and Services, 3.2 Shifts in Demand and Supply for Goods and Services, 3.3 Changes in Equilibrium Price and Quantity: The Four-Step Process, Introduction to Labor and Financial Markets, 4.1 Demand and Supply at Work in Labor Markets, 4.2 Demand and Supply in Financial Markets, 4.3 The Market System as an Efficient Mechanism for Information, 5.1 Price Elasticity of Demand and Price Elasticity of Supply, 5.2 Polar Cases of Elasticity and Constant Elasticity, 6.2 How Changes in Income and Prices Affect Consumption Choices, 6.4 Intertemporal Choices in Financial Capital Markets, Introduction to Cost and Industry Structure, 7.1 Explicit and Implicit Costs, and Accounting and Economic Profit, 7.2 The Structure of Costs in the Short Run, 7.3 The Structure of Costs in the Long Run, 8.1 Perfect Competition and Why It Matters, 8.2 How Perfectly Competitive Firms Make Output Decisions, 8.3 Entry and Exit Decisions in the Long Run, 8.4 Efficiency in Perfectly Competitive Markets, 9.1 How Monopolies Form: Barriers to Entry, 9.2 How a Profit-Maximizing Monopoly Chooses Output and Price, Chapter 10. B) economic resources are perfectly shiftable between the production of the two products. Suppose a society desires two products, healthcare and education. Clearly, Brazil has a lower opportunity cost of producing sugar cane (in terms of wheat) than the U.S. 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. 16) Explain why societies cannot make a choice above their production possibilities frontier and should not make a choice below it The production possibility frontier (PPF) is used to illustrate the different combination of two good or services produced with all the resources available. 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. Question 35. Most important, the production possibilities frontier clearly shows the tradeoff between healthcare and education. Different points of PPF denote alternative combination of two commodities that the country can choose to produce. This is because its slope is given by the relative prices of the two goods. Now imagine that some of these resources are diverted from healthcare to education, so that the economy is at point B instead of point A. 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). Straight-line PPFs show constant If the production possibility curve for a two-good economy is a straight line, then? An inefficient organization operates with long delays and high costs, while an efficient organization meets schedules, is focused, and performs within budget. equal quantities of the two goods will be produced at each possible point on the curve. What is the shape of production possibility curve: (a) Concave to the origin ... Straight line (d) None of the above. This is known as opportunity cost. Production possibilities curve concave to the origin. With trade, goods are produced where the opportunity cost is lowest, so total production increases, benefiting both trading parties. The budget constraints presented earlier in this chapter, showing individual choices about what quantities of goods to consume, were all straight lines. While every society must choose how much of each good it should produce, it does not need to produce every single good it consumes. Explain why societies cannot make a choice above their production possibilities frontier and should not make a choice below it. Its always drawn as a curve and not a straight line because there a cost involved in making a choice i.e when the quantity of one good produced is higher and the quantity of the other is low. Since resources are scarce, increasing... See full answer below. At point A, all available resources are devoted to healthcare and none are left for education. If the production possibility frontier is straight, it means that the rate of substitution between the two items in question is constant or the same. But it does not have enough resources to produce outside the PPF. At its most basic, allocative efficiency means producers supply the quantity of each product that consumers demand. Expert Answer . This problem has been solved! Outside the PPF curve is impossible. This is known as opportunity cost. The second is the absence of specific numbers on the axes of the PPF. When countries engage in trade, they specialize in the production of the goods that they have comparative advantage in, and trade part of that production for goods they do not have comparative advantage in. Monetary Policy and Bank Regulation, Introduction to Monetary Policy and Bank Regulation, 28.1 The Federal Reserve Banking System and Central Banks, 28.3 How a Central Bank Executes Monetary Policy, 28.4 Monetary Policy and Economic Outcomes, Chapter 29. However, any choice inside the production possibilities frontier is productively inefficient and wasteful because it is possible to produce more of one good, the other good, or some combination of both goods. equal quantities of the two products will be produced at each possible point on the curve. The study of economics does not presume to tell a society what choice it should make along its production possibilities frontier. The slope of the PPF gives the opportunity cost of producing an additional unit of wheat. The specific choice along a production possibilities frontier that reflects the mix of goods society prefers is the choice with allocative efficiency. By the end of this section, you will be able to: Just as individuals cannot have everything they want and must instead make choices, society as a whole cannot have everything it might want, either. See all questions in Production–possibility frontier. The curve is a downward-sloping straight line, indicating that there is a linear, negative relationship between the production of the two goods. Monopoly and Antitrust Policy, Introduction to Monopoly and Antitrust Policy, Chapter 12. This can be illustrated by the PPFs of the two countries in Figure 3. For example, point R is productively inefficient because it is possible at choice C to have more of both goods: education on the horizontal axis is higher at point C than point R (E2 is greater than E1), and healthcare on the vertical axis is also higher at point C than point R (H2 is great than H1). In other words, the PPF would rotate clockwise around the horizontal intercept. b. 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. 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. For example, production could take place at point D, with 9 million units of food and 3 million units of cloth being produced. Issues in Labor Markets: Unions, Discrimination, Immigration, Introduction to Issues in Labor Markets: Unions, Discrimination, Immigration, Chapter 16. A straight-line production possibilities curve has a constant opportunity cost. How did the war affect Germany’s production possibilities curve? Allocative efficiency requires productive efficiency, because it pertains to choices along the production possibilities frontier. As it does, the production possibilities frontier for a society will tend to shift outward and society will be able to afford more of all goods. In the chapter on International Trade you will learn that countries’ differences in comparative advantage determine which goods they will choose to produce and trade. In the second case, as resources grow over a period of years (e.g., more labor and more capital), the economy grows. 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. Could a nation be producing in a way that is allocatively efficient, but productively inefficient? What is productive efficiency? Answer: (a) Concave to the origin. …  opportunity costs increase as production of one good rises. Inside the PPF curve is inefficient or involves unemployed workers. Sort by: Top Voted. Increasing opportunity cost of specializing in production. the two goods are equally important to consumers. Every economy faces two situations in which it may be able to expand consumption of all goods. Government Budgets and Fiscal Policy, Introduction to Government Budgets and Fiscal Policy, 30.3 Federal Deficits and the National Debt, 30.4 Using Fiscal Policy to Fight Recession, Unemployment, and Inflation, 30.6 Practical Problems with Discretionary Fiscal Policy, Chapter 31. If the production possibilities curve is a straight line, the two goods will sell at the same market prices. Now consider the other end, at the lower right, of the production possibilities frontier. Suppose it considers moving from point B to point C. What would the opportunity cost be for the additional education? Draw Farmer Brown's production possibilities frontier (PPF), corn on horizontal axis and tobacco on vertical … Combinations of output that are inside the production possibilities … By moving from point A to point B Brazil would give up a relatively small quantity in wheat production to obtain a large production in sugar cane. 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. Answer. The production possibilities frontier can illustrate two kinds of efficiency: productive efficiency and allocative efficiency. 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. As a result, the curve cannot be a straight line. Next: 2.3 Confronting Objections to the Economic Approach, 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. Below is an example of the trade-off between investing people in high tech industries versus entertainment industries. It's impossible to draw a straight line through those 3 points. The most important difference between the two graphs, though, is that a budget constraint is a straight line, while a production possibilities curve is typically bowed outwards, i.e. If the production possibilities curve is a straight line: economic resources are perfectly substitutable between the production of the two products. Inefficient and Infeasible Points. 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. 1.1 What Is Economics, and Why Is It Important?
