Basically, what this means is that as an economy devotes more of its resources to one kind of product, it becomes less efficient.
Productive efficiency and Pareto efficiency A PPF production possibility frontier Production possibility frontier different combinations takes the form of the curve illustrated above.
An economy that is operating on the PPF is said to be efficientmeaning that it would be impossible to produce more of one good without decreasing production of the other good. 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.
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.
B if guns are of interest, C if more butter is needed, D if an equal mix of butter and guns is required. 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.
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. An efficient point is one that lies on the production possibilities curve.
At any such point, more of one good can be produced only by producing less of the other. If we are interested in one good, a composite score of the other goods can be generated using different techniques. Opportunity cost 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.
Points along the curve describe the tradeoff between the goods. 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.
Opportunity cost is measured in the number of units of the second good forgone for one or more units of the first good. If the shape of the PPF curve is a straight-line, the opportunity cost is constant as production of different goods is changing.
But, opportunity cost usually will vary depending on the start and end points. In the diagram on the right, 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.
At point C, the economy is already close to its maximum potential butter output. To produce 10 more packets of butter, 50 guns must be sacrificed as with a movement from C to D.
The ratio of gains to losses is determined by the marginal rate of transformation. Marginal rate of transformation[ edit ] Marginal rate of transformation increases when the transition is made from AA to BB. The slope of the production—possibility frontier PPF at any given point is called the marginal rate of transformation MRT.
The slope defines the rate at which production of one good can be redirected by reallocation of productive resources into production of the other.
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 measures how much of good Y is given up for one more unit of good X or vice versa.Please find a list of our global and regional case studies below.

Effective Modeling for Good Decision-Making What is a model? A Model is an external and explicit representation of a part of reality, as it is seen by individuals who wish to use this model to understand, change, manage and control that part of reality.
Production possibility frontiers. A PPF shows all the possible combinations of two goods, These combinations can also be shown graphically, the result being a production possibility frontier.
The production possibility frontier (PPF) for computers and textbooks is shown here. where L S and L NS are susceptible and non-susceptible labour inputs and C is computer capital.
Computer capital is supplied perfectly elastically at market price per efficiency unit, where the market price is falling exogenously with time due to technological progress. The production possibility curve (PPC), also referred to as the production possibility frontier (PPF) or transformation curve, depicts the maximum output possibilities for two goods contingent.
