07 of 09 Measurement of Productivity and Efficiency: Theory and Practice. D)technology is rapidly expanding. Sickles, R., & Zelenyuk, V. (2019). For an extensive discussion of various types of efficiency measures ( Farrell, Hyperbolic, Directional, Cost, Revenue, Profit, Additive, etc.) Allocative efficient is only achieved when the economy produces at quantities that match societal preference. A production possibilities frontier is a straight line when a. the more resources the economy uses to produce one good, the fewer resources it has available to produce the other good. C)opportunity costs are constant. Our experts can answer your tough homework and study questions. [16], With economies of scale, the PPF would curve inward, with the opportunity cost of one good falling as more of it is produced. 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. The correct answer is b) The production possibilities frontier is usually bowed outward Explanation: The production possibilities frontier can bow outward (usually), inward (sometimes), or be a straight line … c. producing additional units of one good results in proportionately smaller reductions in the output of the other good. If the shape of the PPF curve is a straight-line, the opportunity cost is constant as production of different goods is changing. - Definition & Example, The Elasticity of Demand: Definition, Formula & Examples, Business 121: Introduction to Entrepreneurship, CSET Business Subtest I (175): Practice & Study Guide, CSET Business Subtest II (176): Practice & Study Guide, CSET Business Subtest III (177): Practice & Study Guide, ILTS Business, Marketing, and Computer Education (171): Test Practice and Study Guide, Introduction to Management: Help and Review, UExcel Introduction to Macroeconomics: Study Guide & Test Prep, Information Systems and Computer Applications: Certificate Program, UExcel Business Law: Study Guide & Test Prep, Biological and Biomedical The slope of the production–possibility frontier (PPF) at any given point is called the marginal rate of transformation (MRT). At A all resources go to healthcare and at B, most go to 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. 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. Points that are unattainable can be achieved through external trade and economic growth. At point C, the economy is already close to its maximum potential butter output. But, opportunity cost usually will vary depending on the start and end points. ELI5:Why is a production possibility frontier displayed as a curve, rather than a straight line? Samuelson, Paul A. ', Figure 6a: Standard PPF: increasing opportunity cost, Figure 6b: Straight line PPF: constant opportunity cost, Figure 6c: inverted PPF: decreasing opportunity cost. A production possibilities frontier is a straight line when a. the rate of tradeoff between the two goods being produced depends on how much of each good is being produced. -----If the production possibilities curve is a straight line: The kingdom of Ruritania produces cuckoo clocks... An outward shift of the production possibilities... 3. [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. 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. Don't use plagiarized sources. This is known as opportunity cost. B. law of constant opportunity costs applies. (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. E. implies that opportunity costs will rise as production levels fall. Different points of PPF denote alternative combination of two commodities that the country can choose to produce. [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. This makes intuitive sense as straight lines have a constant slope. Production-Possibility Frontier delineates the maximum amount/quantities of outputs (goods/services) an economy can achieve, given fixed resources (factors of production) and fixed technological progress. When making this graph, a business considers many variables: Its access to resources, strengths and skill set. The shape of the PPF is typically curved outward, rather than straight. If, for example, the (absolute) slope at point BB in the diagram is equal to 2, to produce one more packet of butter, the production of 2 guns must be sacrificed. Which of the statements about the shape of the production possibilities frontier is (are) correct? [15] This case reflects a situation where resources are not specialised and can be substituted for each other with no added cost. A production possibilities frontier is a straight line when Select one a the more resources the economy uses to produce one good, the fewer resources it has available to produce the other good. Examples include importations of resources and technology, and the increase in the production of goods and services. February 12, 2014, sahan, Leave a comment. However, the cost of producing successive units of butter will increase as resources that are more and more specialized in gun production are moved into the butter industry. The production-possibility frontier can be constructed from the contract curve in an Edgeworth production box diagram of factor intensity. [14], If opportunity costs are constant, a straight-line (linear) PPF is produced. If the production possibilities curve is a straight line, then the A. opportunity cost of producing one good is zero. [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. 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. It shows that Econ Isle can produce a maximum of 12 gadgets and 6 widgets or any other combination along the line. 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. 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). C. producer can produce more of both goods simultaneously. Economics In Economics, I'd expect a PPF graph to be a straight line between using all resources to produce Product Y and all resources being used to produce product X. A PPF illustrates several economic concepts, such as allocative efficiency, economies of scale, opportunity cost (or marginal rate of transformation), productive efficiency, and scarcity of resources (the fundamental economic problem that all societies face).[1]. [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. Points within the curve show when a country’s resources are not being fully utilised. Choices outside the PPF are unattainable and choices inside the … Concepts covered include efficiency, inefficiency, economic growth and contraction, and recession. and their relationships, see Sickles and Zelenyuk (2019, Chapter 3). [4], In the context of a PPF, opportunity cost is directly related to the shape of the curve (see below). A production possibilities frontier is a straight line when A. the more resources the economy uses to produce one good, the fewer resources it has available to produce the other good. A production–possibility frontier (PPF), production possibility curve (PPC), or production possibility boundary (PPB), or Transformation curve/boundary/frontier is a curve which shows various combinations of the amounts of two goods which can be produced within the given resources and technology/a graphical representation showing all the possible options of output for two products that can be produced using all factors of production, where the given resources are fully and efficiently utilized per unit time. 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. D. causes the production possibilities frontier to be a straight line. Since it is a boundary line it is called a frontier. If every trade-off were the same, it would create a straight line. Only points on or within a PPF are actually possible to achieve in the short run. A. causes the production possibilities curve to shift outward. As far as i know it can be either concave, convex or a straight line. 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). A … In contrast, if the economy is operating below the curve, it is said to be operating inefficiently because it could reallocate resources in order to produce more of both goods or some resources such as labor or capital are sitting idle and could be fully employed to produce more of both goods. c. the rate of tradeoff between the two goods being produced is constant. 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. A. increasing the production of one good by x units entails no opportunity cost in terms of the other good. 7. b.an economy is interdependent and engaged in trade instead of self-sufficient. Production Possibilities Frontier Framework Assume that two products are being produced: benches and chairs. 80. This page was last edited on 1 December 2020, at 20:35. An efficient point is one that lies on the production possibilities curve. Similarly, not all Pareto efficient points on the frontier are Allocative efficient. [12] The example used above (which demonstrates increasing opportunity costs, with a curve concave to the origin) is the most common form of PPF. Answer and Explanation: c. negatively sloped straight line. 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. Points within the curve show when a country’s resources are not being fully utilised The ratio of gains to losses is determined by the marginal rate of transformation. Consider the situation in … (1947, Enlarged ed. If this nation devotes all its resources and technology to produce good A, the maximum it can produce is 30 units in a month. 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]. 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. Thus, MRT increases in absolute size as one moves from the top left of the PPF to the bottom right of the PPF.[11]. b. the more resources the economy uses to produce one good, the fewer resources it has available to produce the other good. In other words, the opportunity cost of producing 2 widgets is now 4 gadgets. Points along the curve describe the tradeoff between the goods. 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. It is traditionally used to show the movement between committing all funds to consumption on the y-axis versus investment on the x-axis. C) the opportunity costs of the products are constant. Production possibility curve or production possibility frontier is the graph that represents the combination of two commodities that the economy can produce. In the above diagram, the new technique results in wine production that is double its previous level for any level of grain production. The trade-off of producing one more extra unit of good X is: -1/5 Suppose there is a nation that can produce only two goods (good A and good B). 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. Specialization in producing successive units of a good determines its opportunity cost (say from mass production methods or specialization of labor). By doing so, it defines productive efficiency in the context of that production set: a point on the frontier indicates efficient use of the available inputs (such as points B, D and C in the graph), a point beneath the curve (such as A) indicates inefficiency, and a point beyond the curve (such as X) indicates impossibility. A production possibilities frontier is a straight line when a. the more resources the economy uses to produce one good, the fewer resources it has available to produce the other good. All rights reserved. b. an economy is interdependent and engaged in trade instead of self-sufficient. 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. The PPC reflects the concept of choice, scarcity, and trade-off. C. is illustrated by a point outside the production possibilities curve. C. the economy is producing efficiently. 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. A production possibility frontier will be a straight line when: A. efficiency is achieved. Samuelson, Paul A., and William D. Nordhaus (2004). However, most economic contractions reflect not that less can be produced but that the economy has started operating below the frontier, as typically, both labour and physical capital are underemployed, remaining therefore idle. b. the society will be producing inside its production possibilities frontier. With increasing production of butter, workers from the gun industry will move to it. Because a company’s ability to produce two distinct items is not always equal, the chart reveals a bowed-shape curve instead of a linear function. Conversely, the PPF will shift inward if the labour force shrinks, the supply of raw materials is depleted, or a natural disaster decreases the stock of physical capital. Pareto efficiency is achieved when the marginal rate of transformation (slope of the frontier/opportunity cost of goods) is equal to all consumers' marginal rate of substitution. A Healthcare vs. Education Production Possibilities Frontier This production possibilities frontier shows a tradeoff between devoting social resources to healthcare and devoting them to education. The shape of the PPF is typically curved outward, rather than straight. Any societyâ s choice problem is illustrated by using a diagram, called production possibilities curve (PPC) or production possibilities frontier (PPF). b. an economy is interdependent and engaged in trade instead of self-sufficient. B. the goods on the axes are perfect substitutes in consumption. Cambridge: Cambridge University Press. Equilibrium for a firm will be the combination of outputs on the PPF that is most profitable.
