why is the ppf downward sloping

An economy achieves a point on its production possibilities curve only if it allocates its factors of production on the basis of comparative advantage. While even smaller than the second plant, the third was primarily designed for snowboard production but could also produce skis. Creative Commons Attribution License Given the labor and the capital available at both plants, it can produce the combinations of the two goods at the two plants shown. To see this relationship more clearly, examine Figure 2.3 The Slope of a Production Possibilities Curve. Thats the trade-off this society faces. The opportunity cost would be the healthcare society has to give up. However, putting those marginal dollars into education, which is completely without resources at point A, can produce relatively large gains. In the book 'Principles of Microeconomics' where this article is taken from, budget constraints are discussed first then PPF. We measure the additional education by the horizontal distance between B and C. The foregone healthcare is given by the vertical distance between B and C. The slope of the PPF between B and C is (approximately) the vertical distance (the rise) over the horizontal distance (the run). Productive efficiency means it is impossible to produce more of one good without decreasing the quantity that is produced of another good. Sort by: To shift from B to B, Alpine Sports must give up two more pairs of skis per snowboard. These days, when you open a PPF account, the balance is available online. Points that lie on the PPF illustrate combinations of output that are. c. relatively cheap at low levels of output. The steeper the curve, the greater the opportunity cost of an additional snowboard. Just because you can make a billion phones because it is along the PPF curve is not reasonable. If all the factors of production that are available for use under current market conditions are being utilized, the economy has achieved full employment. Such an allocation implies that the law of increasing opportunity cost will hold. So, a society must choose between tradeoffs in the present. Just as with Alphonsos budget constraint, the slope of the production possibilities frontier shows the opportunity cost. b. a downward-sloping curve that is bowed inward. When countries engage in trade, they specialize in the production of the goods that they have a comparative advantage in, and trade part of that production for goods they do not have a comparative advantage in. Draw a market which you believe would represent the market for a cure to the current Coronavirus. Economists say that an economy has a comparative advantage in producing a good or service if the opportunity cost of producing that good or service is lower for that economy than for any other. Instead of the bowed-out production possibilities curve ABCD, we get a bowed-in curve, ABCD. Now suppose that a large fraction of the economys workers lose their jobs, so the economy no longer makes full use of one factor of production: labor. In effect, the production possibilities frontier plays the same role for society as the budget constraint plays for Alphonso. Understand specialization and its relationship to the production possibilities model and comparative advantage. I'm pretty sure it wasn't mentioned in previous videos in this section. The Production Possibility Frontier (PPF): Assumptions, Characteristics At point A, all available resources are devoted to healthcare and none are left for education. Should the government promote the product or what? Production of all other goods and services falls by OA OB units per period. labor, land, capital, raw materials, etc.). Thus, all choices along a given PPF like B, C, and D display productive efficiency, but R does not. With all three plants producing only snowboards, the firm is at point D on the combined production possibilities curve, producing 300 snowboards per month and no skis. The production of both goods rises. The PPF looks a bit like a budget constraint. The answer is Yes, and the key lies in comparative advantage. b. used efficiently. Because the PPF is downward sloping from left to right, the only way society can obtain more education is by giving up some healthcare. Such specialization is typical in an economic system. c. a downward-sloping straight line. Countries tend to have different opportunity costs of producing a specific good, either because of different climates, geography, technology, or skills. This situation would be extreme and even ridiculous. This is because its slope is given by the relative prices of the two goods, which from the point of view of an individual consumer, are fixed, so the slope doesn't change. This time, however, imagine that Alpine Sports switches plants from skis to snowboards in numerical order: Plant 1 first, Plant 2 second, and then Plant 3. We can think of each of Ms. Ryders three plants as a miniature economy and analyze them using the production possibilities model. 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. Production Possibilities Frontier - saylordotorg.github.io If you're behind a web filter, please make sure that the domains *.kastatic.org and *.kasandbox.org are unblocked. The slope of Plant 1s production possibilities curve measures the rate at which Alpine Sports must give up ski production to produce additional snowboards. During the Second World War, Germanys factories were decimated. See full answer below. If you use it this way . Direct link to Louis Lepper's post I don't get the answer to, Posted 3 years ago. If on the one hand, very few resources are currently committed to education, then an increase in resources used can bring relatively large gains. Plant 3 has a comparative advantage in snowboard production because it is the plant for which the opportunity cost of additional snowboards is lowest. If the firm wishes to increase snowboard production, it will first use Plant 3, which has a comparative advantage in snowboards. Thus, all choices along a given PPF like B, C, and D display productive efficiency, but R does not. 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. Suppose an economy fails to put all its factors of production to work. In our example, Brazil has an absolute advantage in sugar cane and the U.S. has an absolute advantage in wheat. Choices outside the PPF are unattainable and choices inside the PPF are wasteful. The combined production possibilities curve for the firms three plants is shown in Figure 2.5 The Combined Production Possibilities Curve for Alpine Sports. 2.4: The Ricardian Model Production Possibility Frontier 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. Here, the opportunity cost is lowest at Plant 3 and greatest at Plant 1. Most importantly, the production possibilities frontier clearly shows the tradeoff between healthcare and education. It need not imply that a particular plant is especially good at an activity. In the graph, healthcare is shown on the vertical axis and education is shown on the horizontal axis. Want to cite, share, or modify this book? 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. We recommend using a That is certainly one possible way of allocating a societys resources, but it would mean there would be no resources left for education. That would bring ski production to 300 pairs, at point B. Suppose a society allocated all of its resources to producing health care. Figure 2.4 Production Possibilities at Three Plants shows production possibilities curves for each of the firms three plants. Society can choose any combination of the two goods on or inside the PPF. For government, this process often involves trying to identify where additional spending could do the most good and where reductions in spending would do the least harm. Why is a production possibilities frontier typically drawn as a curve, rather than a straight line? 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). Inefficient production implies that the economy could be producing more goods without using any additional labor, capital, or natural resources. That will require shifting one of its plants out of ski production. In this way, the law of diminishing returns produces the outward-bending shape of the production possibilities frontier. So it is constant because the slope is constantly the same. Instead, it lays out the possibilities facing the economy. One can easily see this with a simple observation of the extreme production points in the PPFs of the two countries. Due to the limitation of resources and technology, if the economy wants to produce more units of good 1, it has to reduce the quantity of good 2, which depicts the downwards slope of the PPF. Where will it produce them? A PPF curve is downward sloping, that is, it shows a negative relationship between the goods. We assume that the factors of production and technology available to each of the plants operated by Alpine Sports are unchanged. What are the similarities between a consumers budget constraint and societys production possibilities frontier, not just graphically but analytically? Plant R has a comparative advantage in producing calculators. For example in the marginal opportunity cost schedule given in Q. Whats the difference between a budget constraint and a PPF? All choices on the PPF in Figure 2.4, including A, B, C, D, and F, display productive efficiency. The Great Depression was a costly experience indeed. That's the trade-off this society faces. Thus, the slope of the PPF is relatively flat near the vertical-axis intercept. Take another look at the production possibilities frontier in this video about the imaginary Econ Isle.. What determines how far a PPF is from the origin. Here they are, the 100 best restaurants in New York City, ranked. 1.12 we . What happen if society wants less products than what are on the productive efficiency point? Figure 2. All choices along a production possibilities frontier display productive efficiency; that is, it is impossible to use societys resources to produce more of one good without decreasing production of the other good. Workers, for example, specialize in particular fields in which they have a comparative advantage. 1999-2023, Rice University. If Alpine Sports were to produce still more snowboards in a single month, it would shift production to Plant 2, the facility with the next-lowest opportunity cost. This situation is illustrated by the production possibilities frontier in this graph. Use the production possibilities model to distinguish between full employment and situations of idle factors of production and between efficient and inefficient production. When an economy is operating on its production possibilities curve, we say that it is engaging in efficient production. (Many students are helped when told to read this result as 2 pairs of skis per snowboard.) We get the same value between points B and C, and between points A and C. Figure 2.2 A Production Possibilities Curve. The curve is a downward-sloping straight line, indicating that there is a linear, negative relationship between the production of the two goods. People are having cosmetic surgery on every part of their bodies, but no high school or college education exists! The production possibilities model suggests that specialization will occur. 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. To understand why the PPF is curved, start by considering point A at the top left-hand side of the PPF. As it does, the production possibilities frontier for a society will shift outward and society will be able to afford more of all goods. The bowed-out production possibilities curve for Alpine Sports illustrates the law of increasing opportunity cost. For example, children are seeing a doctor every day, whether they are sick or not, but not attending school. However, improvements in productive efficiency take time to discover and implement, and economic growth happens only gradually. 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. 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. We shall examine the significance of the bowed-out shape of the curve in the next section. The opportunity cost of an additional snowboard at each plant equals the absolute values of these slopes. 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. On this graph, the y-axis is Healthcare, and the x-axis is Education.. A production possibilities frontier showing health care and education. Imagine that you are suddenly completely cut off from the rest of the economy. Why does the shape of the ppf slope downwards to the right - Answers 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. The law of increasing opportunity cost tells us that, as the economy moves along the production possibilities curve in the direction of more of one good, its opportunity cost will increase. The following. Much of the land in the United States has a comparative advantage in agricultural production and is devoted to that activity. 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. The reason for these straight lines was that the relative prices of the two goods in the consumption budget constraint determined the slope of the budget constraint. With trade, manufacturers produce goods where the opportunity cost is lowest, so total production increases, benefiting both trading parties. However, additional increases typically cause relatively larger increases in the opportunity cost of reducing crime, and paying for enough police and security to reduce crime to nothing at all would be a tremendously high opportunity cost. With trade, goods are produced where the opportunity cost is lowest, so total production increases, benefiting both trading parties. These resources were not put back to work fully until 1942, after the U.S. entry into World War II demanded mobilization of the economys factors of production. Hong Kong, with its huge population and tiny endowment of land, allocates virtually none of its land to agricultural use; that option would be too costly. 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. However, it would not have any resources to produce education. This production possibilities curve shows an economy that produces only skis and snowboards. Producing a snowboard in Plant 3 requires giving up just half a pair of skis. That is the tradeoff society faces. Why Is A Ppf Curved? - IosFuzhu Now consider what would happen if Ms. Ryder decided to produce 1 more snowboard per month. The study of economics does not presume to tell a society what choice it should make along its production possibilities frontier. Since we have assumed that the economy has a fixed quantity of available resources, the increased use of resources for security and national defense necessarily reduces the number of resources available for the production of other goods and services. Why does the PPF have a different shape? 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. Suppose further that all three plants are devoted exclusively to ski production; the firm operates at A. In other words production of one good can be increased only after sacrificing some quantity of other good. In short, the slope of the PPF from point F to D would be steep, and the opportunity cost of education in terms of healthcare would be high. 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. An economy that fails to make full and efficient use of its factors of production will operate inside its production possibilities curve. all the doctors and all the teachers) are devoted to providinghealth care and none isleft for education. Figure 2.4 illustrates these ideas using a production possibilities frontier between healthcare and education. In that case, it produces no snowboards. That is the tradeoff society faces. The production possibilities curve shown suggests an economy that can produce two goods, food and clothing. why is the ppf downward sloping The reason for the shape of the Production Possibilities Curve (PPC) is something called the law of increasing opportunity costs. Two years later she added a third plant in another town. Plants 2 and 3, if devoted exclusively to ski production, can produce 100 and 50 pairs of skis per month, respectively. MicroEcon Ch 2 Quiz Flashcards | Quizlet Wed love your input. Specialization means that an economy is producing the goods and services in which it has a comparative advantage. Characteristics of PPF: The two basic characteristics or features of PPF are: 1. What if on the horizontal axis of the PPF we plotted cigarettes, cocaine, opium and other drugs while on the vertical axis we plotted nuclear bombs or some other undesirable product? After all, thats not what they were trained for. The slope equals 2 pairs of skis/snowboard (that is, it must give up two pairs of skis to free up the resources necessary to produce one additional snowboard). Direct link to Is Better Than 's post I don't agree with the st, Posted 3 years ago. Solved Explain, in your own words, why the production - Chegg A production possibilities frontier showing health care and education. Conversely, the U.S. can produce a lot of wheat per acre, but not much sugar cane. A PPF w/Constant Opportunity Cost is a linear line, meaning the line is straight (not curved), and To be linear means the change between any two points anywhere on the line will be consistent. Due to the limitation of resources and technology, if the economy. A budget constraint shows the different combinations of goods and services a consumer can purchase with their fixed budget. If it is using the same quantities of factors of production but is operating inside its production possibilities curve, it is engaging in inefficient production. The Production Possibilities Frontier (PPF) is a graph that shows all the different combinations of output of two goods that can be produced using available resources and technology. Suppose that Alpine Sports is producing 100 snowboards and 150 pairs of skis at point B. One, of course, was increased defense spending. ANSWER: c 19. 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. Figure 2.4 Production Possibilities at Three Plants. Check with . The decision to devote more resources to security and less to other goods and services represents the choice we discussed in the chapter introduction. PPF has a negative slope due to it's downward sloping nature. But the amount of education gained is great, because thats what teachers are trained for. Direct link to nishankpatil25's post How to use clear it up fe, Posted 3 years ago. In material terms, the forgone output represented a greater cost than the United States would ultimately spend in World War II. Because the PPF is downward sloping from left to right, the only way society can obtain more education is by giving up some healthcare. To construct a combined production possibilities curve for all three plants, we can begin by asking how many pairs of skis Alpine Sports could produce if it were producing only skis. The second major difference is the absence of specific numbers on the axes of the PPF. Producing more skis requires shifting resources out of snowboard production and thus producing fewer snowboards. So it makes sense for teachers to be reallocated from healthcare to education. The greater the absolute value of the slope of the production possibilities curve, the greater the opportunity cost will be. I don't understand: if we don't raise amount of resourches for healtccare, why we reduce amount of resourches for education? 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.
