Production Possibility Curve Definition and Labeled Diagram
The concept of production possibility curve (PPC) is vital in economics and Commerce. It shows how economies must make choices about resource allocation due to scarcity. Understanding the PPC helps students perform well in school and competitive exams, and also understand economic trade-offs in business and daily life.
| Concept | Description |
|---|---|
| Production Possibility Curve (PPC) | Graph showing maximum possible output combinations of two goods produced with limited resources. |
| Production Possibility Frontier (PPF) | Alternative term for PPC; highlights the boundary of efficient production. |
| Opportunity Cost | What must be given up to produce more of one good, shown by the movement along the curve. |
| Efficiency | Points lying on the curve mean resources are fully and efficiently used. |
| Inefficiency/Unemployment | Points inside the curve show underutilized resources or unemployment. |
| Unattainable Points | Points outside the curve cannot be achieved with current resources and technology. |
Production Possibility Curve Definition
The production possibility curve (PPC) is a graph that shows all the possible combinations of two goods or services that can be produced using available resources, given the state of technology. The PPC highlights the concept of scarcity, economic trade-offs, and opportunity cost. This topic is fundamental for exams and business decision-making.
PPC Schedule and Diagram
A PPC schedule is a table listing different possible production combinations. The diagram is a graph based on the schedule. Both help visualize the economic choices and trade-offs an economy faces. Below is a common PPC schedule and a diagram description.
| Combination | Good A (e.g., Watermelons) | Good B (e.g., Pineapples) |
|---|---|---|
| P | 0 | 130,000 |
| Q | 15,000 | 120,000 |
| R | 30,000 | 105,000 |
| S | 45,000 | 85,000 |
| T | 60,000 | 60,000 |
In a typical PPC diagram, Good A is measured on the X-axis, and Good B on the Y-axis. The curve is downward sloping and concave to the origin, showing increasing opportunity cost. Points P to T from the table above would be plotted to form the curve.

Features of Production Possibility Curve
- Downward sloping: More of one good can be produced only by reducing the production of the other.
- Concave shape: Due to the law of increasing opportunity cost.
- Shows resource allocation between two goods at full efficiency.
- Any point on the PPC indicates efficient use of resources.
- Points inside show inefficiency or unemployment; points outside are unattainable.
Assumptions of Production Possibility Curve
- Resources are fixed in quantity and quality.
- Technology remains constant during analysis.
- Only two goods or types of goods are produced.
- Resources can be shifted freely between the two goods.
- Economy operates with full efficiency.
Significance and Applications of PPC
The PPC is significant for illustrating the basic economic problem of scarcity and choice. It helps students understand opportunity cost, economic efficiency, and the impact of growth or technological progress. In real life, businesses and governments use the model to analyze trade-offs, such as allocating budgets between sectors. For more on opportunity cost, see What is Opportunity Cost on Vedantu.
PPC Example and Practice Question
Suppose a country produces only wheat and rice. Using available resources and technology, the PPC is:
| Combination | Wheat (tons) | Rice (tons) |
|---|---|---|
| A | 0 | 100 |
| B | 20 | 90 |
| C | 40 | 70 |
| D | 60 | 40 |
| E | 80 | 0 |
Stepwise Calculation Example
If moving from combination B to C (from 20 wheat, 90 rice to 40 wheat, 70 rice), the opportunity cost of gaining 20 more tons of wheat is a loss of 20 tons of rice. This demonstrates increasing opportunity cost, a core idea of the PPC.
Shifting the Production Possibility Curve
Economic growth or new technology can shift the PPC outward, showing more goods can be produced overall. Negative shocks, like disasters, can shift it inward. Such changes are important for competitive exams and business strategy.

FAQs on Concept of Production Possibility Curve (PPC) Explained
1. What is the production possibility curve (PPC)?
The production possibility curve (PPC), also known as the production possibility frontier (PPF), is a graphical representation showing the maximum possible combinations of two goods or services an economy can produce using all available resources efficiently. It illustrates the concept of opportunity cost and economic trade-offs.
2. What is the basic concept of PPC?
The PPC demonstrates that with limited resources, producing more of one good requires producing less of another. This trade-off is represented by the downward-sloping curve. Points on the curve represent efficient production, while points inside the curve represent inefficiency, and points outside are unattainable with current resources.
3. What is the concept of PPF?
The production possibility frontier (PPF) is another name for the production possibility curve (PPC). It represents the maximum output combinations of two goods an economy can achieve given its existing resources and technology. Understanding the PPF is crucial for analyzing resource allocation and economic efficiency.
4. What is the concept of production possibility curve with diagram?
The production possibility curve (PPC) is best understood visually. A diagram displays two goods on the x and y axes. The curve itself shows the maximum combinations of these goods producible. The shape of the curve (usually concave) reflects the increasing opportunity cost involved in shifting resources from one good to another. Points inside the curve denote underutilization of resources, while points outside the curve represent currently unattainable production levels.
5. What does a point inside the PPC indicate?
A point inside the PPC signifies that the economy is not using its resources efficiently. This could be due to unemployment or underemployment of resources. The economy is producing below its potential.
6. Why is the PPC concave to the origin?
The PPC's concave shape illustrates the principle of increasing opportunity cost. As an economy shifts resources from producing one good to another, the amount of the second good sacrificed increases. This is due to the varying suitability of resources for different production processes.
7. How can the PPC shift outward?
An outward shift of the PPC indicates economic growth. This happens due to improvements in technology, an increase in the quantity or quality of resources (e.g., more skilled labor, capital investment), or improvements in resource allocation efficiency.
8. What is production possibility curve explain with diagram Class 11?
In Class 11 economics, the production possibility curve (PPC) is a fundamental concept illustrating the trade-offs between producing different goods given limited resources. A diagram shows two goods on axes, and the curve shows the maximum attainable combinations. Understanding this helps explain opportunity cost and economic efficiency. The concave shape reflects increasing opportunity costs.
9. What is the meaning of production possibility curve?
The production possibility curve (PPC) shows the maximum combinations of two goods or services an economy can produce when using all available resources efficiently. It illustrates scarcity, choice, and opportunity cost — fundamental concepts in economics.
10. What is a production possibility schedule?
A production possibility schedule is a table that shows different combinations of two goods that an economy can produce given its resources and technology. It's a tabular representation of the data used to create the production possibility curve (PPC) or production possibility frontier (PPF). It lists different combinations and highlights the opportunity cost involved in shifting resources.
11. Who introduced the concept of production possibility curve?
While the concept of the production possibility curve (PPC) evolved gradually, its popularization and formalization are often attributed to economist Paul Samuelson.
12. Explain concept of production possibility curve with diagram?
The production possibility curve (PPC) is a graph showing the maximum attainable combinations of two goods an economy can produce with its available resources and technology. The curve's downward slope reflects trade-offs, while its concave shape illustrates increasing opportunity costs. A diagram helps visualize efficient and inefficient production levels and the impact of economic growth.
