Therefore the shape of ppc becomes concave to the origin. ️ When a curve is concave to the origin ,it means that it has an increasing slope ,as we move along this curve ,from left to right . 4 where the PPC has the wrong curvature at the endpoints for small 22 or z 1 and has the concave curvature to the origin for the middle ranges. Recall that a property of a concave up part of a graph is that its slope or rate of change is always increasing. Atinput prices (w ∗), costsare at thelevel C(w ). We will call this curve AD, using the letters at each end of the curve. It is also known as Production Possibility Frontier (PPF) or transformation curve. Concavity of PPC implies: A. increasing slope B. decreasing slope C. constant slope D. none of these SOLUTION. It implies that the resources are underutilised. The graph in the figure below is called concave up. Important: Probably the most difficult thing to understand about PPFs is that the slope of the curve is equal to the opportunity cost or trade off of changing which goods are produced.The most basic PPF is a linear one, where the opportunity cost or trade off of switching between goods remains constant. Consider ﬁgure 2. Production possibility curve is concave to the origin. The rate at which an amount of product is sacrificed for producing the amount of another product is called Marginal Rate of Transformation (MRT). Rockafellar [14, p. 82] showsthata concave function deﬁned on an open set(w > 0)is continuous. Production Possibilities Curve as a model of a country's economy. relative risk aversion (CRRA).4 The concavity of W(U), by contrast, involves a value judgment that indicates society’s aversion to inequality in the distribution of utilities. Production Possibility Curve with the help of an example. One way to represent a system described by the One-Dimensional Motion with Constant Acceleration Model graphically is to draw a velocity versus time graph for that system. The bowed-out curve of Figure 2.5 “The Combined Production Possibilities Curve for Alpine Sports” becomes smoother as we include more production facilities. Concavity of PPC implies. The points from A to F in the above diagram shows this. The curve of PPC … 25) The bowed-out (concave) shape of a production possibilities frontier A) is due to the equal usefulness of resources in all activities. Answer Key. ️ When a curve is concave to the origin ,it means that it has an increasing slope ,as we move along this curve ,from left to right . Marginal Decision Making: When some resources are shifted from Use-1 to Use-2 (given technology), the marginal rate of transformation. The curve of PPC shows convex. Answer Key. It shows an increasing slope because more and more of commodity Y is to be sacrificed for every additional unit of commodity X. That is, as we move down along the PPC, the opportunity cost increases. The slope will always be NEGATIVE, because there is a trade off between the two goods, demonstrating the principles of scarcity and opportunity cost. The linear PPC shows constant opportunity cost and the concave PPC shows increasing opportunity cost. PPC is concave to origin because as the production increases, then, in order to produce each additional unit of one good, more and more units of another good needs to be sacrificed.In other words, the opportunity cost of producing one good in terms of another increases. The slope of the PPC is negative at all points on the curve. The graph in the figure below is called, The slope of the tangent line (first derivative) decreases in the graph below. increases. On the left side the slope is negative; however, as x increases the slope gets less and less, -5, -3, -2, till it reaches 0, from where on it increases to 1, 5, 6, etc. It helps in guiding the movement of resources from producer goods to capital goods, such as machines, which, in turn, increases the productive resources of a country for achieving a high production level. The slope of the PPF represents the opportunity cost of moving from one combination of goods to another. As shown in Figure, the attainable combinations are A, B, C, D and E from the given resources. concavity constraints on the PPF and the distance function. Marginal Decision Making: Production Possibility Curve (PPC) is concave to the origin because of the increasing opportunity cost. Ex 5.4.20 Describe the concavity of $\ds y = x^3 + bx^2 + cx + d$.
