a production possibilities frontier is a straight line when

Provide the reason behind it. Production Possibility curves can assume different slopes. [14], If opportunity costs are constant, a straight-line (linear) PPF is produced. The sacrifice in the production of the second good is called the opportunity cost (because increasing production of the first good entails losing the opportunity to produce some amount of the second). An efficient point is one that lies on the production possibilities curve. This curve throws light on the problems of scarcity and choice and illustrates the concept of opportunity cost which is a key concept for decision making and resource allocation. Draw a production possibilities frontier for a society that produce... Essentials of Economics (MindTap Course List) Explain how lower lending standards and lower interest rates can lead to higher house prices. Different points of PPF denote alternative combination of two commodities that the country can choose to produce. … As more of a product is produced, it becomes increasingly more difficult to find resources that are well-suited to producing that product. Samuelson, Paul A. [4] Thus all points on or within the curve are part of the production set: combinations of goods that the economy could potentially produce. In Figure 7, producing 10 more packets of butter, at a low level of butter production, costs the loss of 5 guns (shown as a movement from A to B). 2. A production possibilities frontier is a straight line when. To produce 10 more packets of butter, 50 guns must be sacrificed (as with a movement from C to D). Points that lie to the right of the production possibilities curve are said to be unattainable because they cannot be produced using currently available resources. It measures how much of good Y is given up for one more unit of good X or vice versa. At point C, the economy is already close to its maximum potential butter output. This scenario is represented in the figure titled "Absence of Resource Specialization," which plots the production of right shoes versus left shoes. Sickles, R., & Zelenyuk, V. (2019). So in order to answer this question, we're going to go through a two different sections from Chapter two, Um, and in both, you're doing a scenario of health care versus education. C As output moves from point a to point b to point c along the PPF in the … Measurement of Productivity and Efficiency: Theory and Practice. Practice: Interpreting graphs of the production possibilities curve (PPC) Such a shift reflects, for instance, economic growth of an economy already operating at its full productivity (on the PPF), which means that more of both outputs can now be produced during the specified period of time without sacrificing the output of either good. Market failure (such as imperfect competition or externalities) and some institutions of social decision-making (such as government and tradition) may lead to the wrong combination of goods being produced (hence the wrong mix of resources being allocated between producing the two goods) compared to what consumers would prefer, given what is feasible on the PPF.[3]. Hey, everyone, Today we're going through Problem number 12 from chapter to the textbook, which asks, Why is the production possibilities frontier Jonah's occurred rather than the street life. The straight downward-sloping line is the production possibility frontier. The PPF is a straight line when the resources used to produce the two products are perfectly interchangeable, and thus the opportunity cost of producing more units is constant. B) the two products must have the same price. c. the rate of tradeoff between the two goods being produced is constant. [12] The example used above (which demonstrates increasing opportunity costs, with a curve concave to the origin) is the most common form of PPF. 28. Finally, if the two products are very similar to one another, the production possibility frontier may be shaped more like a straight line. PPCs for increasing, decreasing and constant opportunity cost. D)technology is rapidly expanding. [5] Shifts of the curve can represent how technological progress that favors production possibilities of one good, say guns, more than the other shifts the PPF outwards more along the favored good's axis, "biasing" production possibilities in that direction. The marginal opportunity costs of guns in terms of butter is simply the reciprocal of the marginal opportunity cost of butter in terms of guns. B. law of constant opportunity costs applies. It describes all possible quantity combinations of wine and cheese that can be achieved by the U.S. economy. Examples include importations of resources and technology, and the increase in the production of goods and services. B. an economy is interdependent and engaged in trade instead of self-sufficient. Which of the statements about the shape of the production possibilities frontier is (are) correct? PPFs are normally drawn as bulging upwards or outwards from the origin ("concave" when viewed from the origin), but they can be represented as bulging downward (inwards) or linear (straight), depending on a number of assumptions. C) the opportunity costs of the products are constant. [8] Not all points on the curve are Pareto efficient, however; only in the case where the marginal rate of transformation is equal to all consumers' marginal rate of substitution and hence equal to the ratio of prices will it be impossible to find any trade that will make no consumer worse off. Why PPF are drawn as a curve and not as a straight line. The slope of the production–possibility frontier (PPF) at any given point is called the marginal rate of transformation (MRT). Constructing a Production Possibilities Curve. Graphically bounding the production set for fixed input quantities, the PPF curve shows the maximum possible production level of one commodity for any given production level of the other, given the existing state of technology. For example, if one assumes that the economy's available quantities of factors of production do not change over time and that technological progress does not occur, if the economy is operating on the PPF, production of guns would need to be sacrificed to produce more butter. Cambridge: Cambridge University Press. In which of the following cases is it impossible for both Abby and Liam to benefit from trade? Points that lie strictly to the left of the curve are said to be inefficient, because existing resources would allow for production of more of at least one good without sacrificing the production of any other good. Since it is a boundary line it is called a frontier. a worker would be equally effective whether (s)he was in computing, mining or bus driving. 10. [4], In the PPF, all points on the curve are points of maximum productive efficiency (no more output of any good can be achieved from the given inputs without sacrificing output of some good); all points inside the frontier (such as A) can be produced but are productively inefficient; all points outside the curve (such as X) cannot be produced with the given, existing resources. Specifically, at all points on the frontier, the economy achieves productive efficiency: no more output of any good can be achieved from the given inputs without sacrificing output of some good. If the two production goods depicted are capital investment (to increase future production possibilities) and current consumption goods, the higher the investment this year, the more the PPF would shift out in following years. For the professor, a graph that shows his various possible mixes of output (lectures given per day and papers written per day) is called his. In microeconomics, the PPF shows the options open to an individual, household, or firm in a two good world. A production possibilities frontier is a straight line when. A) Opportunity costs are constant. duction possibilities frontier is a straight line. The production-possibility frontier can be constructed from the contract curve in an Edgeworth production box diagram of factor intensity. That is, as an economy specializes more and more into one product (such as moving from point B to point D), the opportunity cost of producing that product increases, because we are using more and more resources that are less efficient in producing it. An economy that is operating on the PPF is said to be efficient, meaning that it would be impossible to produce more of one good without decreasing production of the other good. Use the following to answer questions 28-29: 28. If a production possibilities frontier is straight line, then production occurs under conditions of: a. increasing opportunity costs b. constant opportunity costs c. decreasing opportunity costs d. infinite opportunity costs e. uncertain opportunity costs A. opportunity costs are constant B. the firm faces increasing costs C. The resources used to produce the two goods are different D. Both A and C 3. The production possibility frontier is bowed out from the origin because: C) economic growth leads to inefficiency. If at AA, the marginal opportunity cost of butter in terms of guns is equal to 0.25, the sacrifice of one gun could produce four packets of butter, and the opportunity cost of guns in terms of butter is 4. Allocative efficient is only achieved when the economy produces at quantities that match societal preference. [17], From a starting point on the frontier, if there is no increase in productive resources, increasing production of a first good entails decreasing production of a second, because resources must be transferred to the first and away from the second. A PPF typically takes the form of the curve illustrated above. Points along the curve describe the tradeoff between the goods. Sometimes, the production possibility frontier does not look like a curve—instead, it’s linear, meaning that it’s simply a straight line. If the shape of the PPF curve is a straight-line, the opportunity cost is constant as production of different goods is changing. It is also called the (marginal) "opportunity cost" of a commodity, that is, it is the opportunity cost of X in terms of Y at the margin. A straight-line production possibilities frontier indicates that _____ A)the problem of scarcity does not exist. Any society’s economic problems can be illustrated by using the production possibilities curve. 79. A production possibilities frontier shows the possible combinations of goods and services that a society can produce with its limited resources. ANS: The PPF is typically bowed-outward due to the law of increasing opportunity costs. If a production possibility frontier is a straight line, it tells us that the opportunity cost of producing one more unit of good X: C) is equal to the inverse of the amount of good Y. [2], From a macroeconomic perspective, the PPF illustrates the production possibilities available to a nation or economy during a given period of time for broad categories of output. Belarus has a comparative advantage in the production of linen, but Russia has an absolute advantage in the production of linen. a. the rate of tradeoff between the two goods being produced depends on how much of each good is being produced. (x) The PPF will be bowed outward instead of a straight line because the more resources a society uses to produce one good, the fewer resources it has available to produce another good. One good can only be produced by diverting resources from other goods, and so by producing less of them. In the long run, if technology improves or if the supply of factors of production increases, the economy's capacity to produce both goods increases; if this potential is realized, economic growth occurs. What is implied if the production possibilities frontier (PPF) is outward bow shaped. An outward shift of the PPC results from growth of the availability of inputs, such as physical capital or labour, or from technological progress in knowledge of how to transform inputs into outputs. Thus, MRT increases in absolute size as one moves from the top left of the PPF to the bottom right of the PPF.[11]. D) there are no opportunity costs. 1983). The slope defines the rate at which production of one good can be redirected (by reallocation of productive resources) into production of the other. At first, the least qualified (or most general) gun workers will be transferred into making more butter, and moving these workers has little impact on the opportunity cost of increasing butter production: the loss in gun production will be small. [14] More specifically, with constant returns to scale, there are two opportunities for a linear PPF: if there was only one factor of production to consider or if the factor intensity ratios in the two sectors were constant at all points on the production-possibilities curve. (1947, Enlarged ed. If a production possibility frontier was a straight line, it would imply that any factor of production was equally good at operating in any industry – i.e. This is the currently selected item. The two main determinants of the position of the PPF at any given time are the state of technology and management expertise (which are reflected in the available production functions) and the available quantities of factors of production (materials, direct labor, and factory overhead). [13] It represents a disparity, in the factor intensities and technologies of the two production sectors. This tradeoff is usually considered for an economy, but also applies to each individual, household, and economic organization. Lesson summary: the production possibilities frontier. Let's assume that two brands of wine are produced, Brand A and Brand B, and that these two brands use the same grapes and production process, differing only in the name on the label. The points from A to F in the above diagram shows this. [15] This case reflects a situation where resources are not specialised and can be substituted for each other with no added cost. With reference to the above production possibilities frontier, ... None of them, because straight-line production possibility curves are never plausible. The rate of tradeoff between producing chairs and producing couches is constant in, Refer to Figure 3-10. Using your own words, … That increase is shown by a shift of the production-possibility frontier to the right. If today's level of production is at the purple point, the level of investment in capital goods (i.e. Cambridge: Cambridge University Press. Samuelson, Paul A., and William D. Nordhaus (2004). Specialization in producing successive units of a good determines its opportunity cost (say from mass production methods or specialization of labor).
