Production Possibility Curve under Constant and Increasing Costs
Each set of equations should be on its own graph and each graph should have Is there a relationship between the opportunity cost and the slope of the PPF? A linear PPF has constant opportunity cost since its slope does not change as. The shape of the curve depends on the assumptions made about the opportunity costs. It may be assumed that opportunity cost is constant. In this case the. The Production Possibilities Curve (PPC) is a model used to show the tradeoffs constant opportunity costs, when the opportunity cost of a good remains.
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. If you have a bowed out curve shaped like the outside of a circle then you have increasing opportunity costs as you specialize, or produce more of the same good. The bowed out PPF means that production favors a mix of products produced, rather than specialization.
If you have a bowed in curve than the opportunity costs decline as you specialize in one good. Examples of these three cases are shown below: A PPF production possibilities frontier shows the different combinations of goods that can be produced in a certain amount of time given fixed inputs.
In general, as the economy increases the quantity supplied of a good, the opportunity cost increases.

And if cost is higher, then sellers need a higher price, resulting in the law of supply. The Production Possibilities Curve Production Possibilities Curve The slope of the production possibilities curve is the opportunity cost of the good measured on the horizontal axis, which in this example is storage sheds.
Opportunity cost values for segments between each pair of points is presented on this production possibilities curve. The opportunity cost of producing the first shed, and the slope of the curve moving from point A to point B, is 5 dozen crab puffs or Moving along the production possibilities curve, the slope becomes steeper that is, the absolute value of the slope increasesreaching a value of an absolute value of between points J and K.
This reflects the law of increasing opportunity cost and results in the convex shape for the production possibilities curve. Three Curves Three alternatives help to illustrate the connection between opportunity cost and the shape of the production possibilities curve.
Increasing Cost Click the [Convex] button: This is the standard convex production possibilities curve with increasing opportunity cost. Because it best reflects the economy, it is the one most commonly seen throughout the study of economics. In this case the economy foregoes increasing amounts of one good when producing more of the other. Constant Cost Click the [Straight Line] button: This is a straight line production possibilities "curve" that indicates constant opportunity cost.
In this case, opportunity cost does not change with production. This is not a realistic reflection of the entire economy, but it can represent the production of some goods. Here the economy foregoes the same amount of one good when producing more of the other. Points inside the curve such as g -represent outputs of less than full employment and are therefore not considered.
Points beyond the curve, such as hrequire more resources than the country possesses and are therefore also beyond consideration.

The full employment output under consideration must be on the production possibilities curve. The slope of the production possibilities curve is the marginal rate of transformation. The slope shows the reduction required in one commodity in order to increase the output of the second commodity.
Since the MRT is constant the slope must be constant and thus the production possibilities curve must be straight line. It can be seen that the MRT of G for D is 8 to 1; reducing the output of D by one unit will provide resources sufficient to expand output of G by 8 units.
Country, Z has a comparative advantage in the production of D; less G has to be given up for each additional unit of D. On the other hand, country W has the comparative advantage in the production of G1 less D has to be given up to produce an additional unit G. With constant returns to scale, trade can take place only when each nation has a different MRT. The greater the difference, the greater is the gains from trade.
The gains from trade rest further upon the amount of trade taking place. Obviously a larger volume of trade allows larger gains from trade and a greater increase in the standard of living.
Under constant cost, the exchange ratio is determined solely by costs; the demand determines only the allocation of available factors between the two branches of production, and hence the relative quantities of G and D which are produced. In this case, demand has nothing to be with the price. It would seem unlikely that most nations would be confronted with constant costs over the substantial range of production.
Constant costs imply that all resources are of equal quality and that they are all equally suited to the production of both commodities. Increasing opportunity costs mean that for each additional unit of G produced, ever-increasing amounts of D must be given up. At first as production G is increased, resources suited to G but not to D are used to increase greatly the output of G and reduce the output of D by little.
Increasing opportunity costs can best be explained by the use of a table.
