The Production Possibility Curve (PPC) is an economic model that considers the maximum possible production (output) that a country can generate if it uses all of its factors of production to produce only two goods/services
Any two goods/services can be used to demonstrate this model
Many PPC diagrams show capital goods & consumer goods on the axes
Capital goods are assets that help a firm or nation to produce output (manufacturing). For example, a robotic arm in a car manufacturing company is a capital good
Consumer goods are end products & have no future productive use. For example, a watch
The use of PPC to depict the maximum productive potential of an economy
The curve demonstrates the possible combinations of the maximum output this economy can produce using all of its resources (factors of production)
At A, its resources are used to produce only consumer goods (300)
At B, its resources are used to produce only capital goods (200)
Points C & D both represent full (efficient) use of an economy's resources as these points fall on the curve. At C, 150 capital goods and 120 consumer goods are produced
The use of PPC to depict opportunity cost
To produce one more unit of capital goods, this economy must give up production of some units of consumer goods (limited resources)
If this economy moves from point C (120, 150) to D (225, 100), the opportunity cost of producing an additional 105 units of consumer goods is 50 capital goods
A movement in the PPC occurs when there is any change in the allocation of existing resources within an economy such as the movement from point C to D
The use of PPC to depict efficiency, inefficiency, attainable and unattainable production
Producing at any point on the curve represents productive efficiency
Any point inside the curve represents inefficiency (point E)
Using the current level of resources available, attainable production is any point on or inside the curve and any point outside the curve is unattainable (point F)
