In microeconomics, a production–possibility frontier (PPF), production possibility curve (PPC), or production possibility boundary (PPB) is a graphical representation showing all the possible options of output for two that can be produced using all factors of production, where the given resources are fully and efficiently utilized per unit time.
Suppose production occurs initially on the production possibility frontier (PPF) at point A. Suppose there is an increase in the labour endowment. This will cause an outward shift in the labour constraint. The PPF and thus production will shift to point B. Production of clothing, the labour-intensive good, will rise from C 1 to C 2.
(This can be obtained by setting F = 0 in their respective PPF equations and summing them up). Here the slope of the joint PPF is −1/2. Here the slope of the joint PPF is −1/2. If we want more fish, we should shift that person who has a comparative advantage in fish hunting (i.e. Friday) out of coconut gathering and into fish hunting.
The production possibilities frontier (PPF) for guns versus butter. Points like X that are outside the PPF are impossible to achieve. Points such as B, C, and D illustrate the trade-off between guns and butter: at these levels of production, producing more of one requires producing less of the other.
When it produces at point B, it can trade with the other country and consume at point S. We now look at our Offer curve and draw a ray at the level 5 Y for 7 X. When full specialization occurs, K then produces at point A, trades and then consumes at point T. The price has reduced to 1 Y for 1 X, and the economy is now at equilibrium.
Productive capacity has a lot in common with a production possibility frontier (PPF) that is an answer to the question what the maximum production capacity of a certain economy is which means using as many economy’s resources to make the output as possible. In a standard PPF graph, two types of goods’ quantities are set.
An example PPF: points B, C and D are all productively efficient, but an economy at A would not be, because D involves more production of both goods. Point X cannot be achieved. Productive efficiency occurs under competitive equilibrium at the minimum of average total cost for each good, such as the one shown here.
If we were to decrease pressure by increasing volume, the equilibrium of the above reaction will shift to the left, because the reactant side has a greater number of moles than does the product side. The system tries to counteract the decrease in partial pressure of gas molecules by shifting to the side that exerts greater pressure.
