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 concept of production possibilities curve?
The production possibilities curve (PPC) is a graphical representation that shows the maximum possible output combinations of two goods or services an economy can produce using its available resources efficiently. It illustrates the concept of opportunity cost by highlighting the trade-offs between different choices. The shape and position of the curve reflect the economy’s resource allocation, technology, and efficiency. By analyzing the PPC, we understand how economic growth, resource scarcity, and opportunity costs influence production decisions. The curve is essential for understanding basic economic problems and helps explain why societies must make choices.
2. What is the basic concept of PPC?
The basic concept of the PPC, or production possibilities curve, is to show the different combinations of two goods that can be produced with a fixed amount of resources and technology. It assumes that resources are fully and efficiently employed. The PPC demonstrates scarcity, choice, and opportunity cost by revealing what is given up when more of one good is produced. Economists use the PPC to analyze production efficiency and the cost of shifting resources between goods. This foundational tool drives home the idea that every economic decision involves trade-offs due to limited resources.
3. What concept does the production possibility curve illustrate?
The production possibility curve mainly illustrates the concept of opportunity cost. As an economy moves along the PPC, producing more of one good means producing less of another due to limited resources. Economic concepts illustrated by the PPC include:
- Scarcity—resources are limited, so not all goods can be produced simultaneously.
- Efficiency—points on the curve show maximum productive use of resources.
- Trade-offs—increasing one type of output decreases another.
- Opportunity Cost—what is sacrificed to gain more of another product.
By understanding the PPC, individuals see how real-world choices reflect scarcity, efficiency, and the economic cost of decisions.
4. What is the concept of PPF?
The production possibility frontier (PPF) is another term for the production possibilities curve. It depicts the maximum output combinations of two products an economy can make when resources are used efficiently and technology is fixed. The PPF makes clear the limitations imposed by scarcity and shows the opportunity cost of choosing to produce one good over another. Points on the frontier are attainable and efficient, while those inside the curve indicate underutilized resources. In short, the PPF visualizes the economic trade-offs every society faces due to limited resources.
5. How does the production possibility curve demonstrate opportunity cost?
The production possibility curve demonstrates opportunity cost by showing how producing more of one good requires sacrificing some of another. As the PPC is typically concave, moving from one point to another on the curve reveals what must be given up to gain more of one product. For example, producing more consumer goods means producing fewer capital goods, and vice versa. The slope of the curve at any point reflects the opportunity cost rate. This visual representation helps economists and policymakers understand the cost of shifting resources and making economic choices.
6. What does a point inside the production possibilities curve represent?
A point inside the production possibilities curve shows that resources are not being used efficiently in an economy. Such a point implies that more of one or both goods could be produced without sacrificing the other, simply by using resources better. This might be due to unemployment, underutilized capital, or inefficiency in production methods. If the economy operates inside the PPC, it is not maximizing its output potential. Efficient and full utilization of resources would place production on the curve itself, rather than inside it.
7. Why is the production possibilities curve usually concave to the origin?
The PPC is generally concave to the origin because resources are not equally efficient in producing all goods. As production shifts from one good to another, increasingly more resources are needed to gain additional units. This reflects the law of increasing opportunity cost. The curve’s shape shows that as you specialize in producing more of one product, you give up larger quantities of the other because resources better suited to one good become less efficient when used for the other. This concavity highlights real-world trade-offs in resource allocation.
8. What factors can cause the production possibility curve to shift?
The PPC shifts when an economy’s productive capacity changes. This can result from several key factors:
- Increase in resources such as labor, land, or capital equipment.
- Improvements in technology that boost productivity.
- Education and skill development among workers.
- Better management or organizational methods.
A rightward shift represents economic growth and more possibilities, while a leftward shift could signify a loss in resources or technological decline. These changes reflect the dynamic nature of economic growth and the importance of investment and innovation.
9. What assumptions are made when drawing a production possibilities curve?
Several key assumptions underlie the construction of a production possibilities curve. These include:
- Resources are fixed—the available amount of land, labor, and capital does not change.
- Technology is constant—no advancements occur during analysis.
- Only two goods are produced—simplifying the model.
- Resources are fully and efficiently used.
These assumptions allow the PPC to focus on trade-offs and opportunity costs within a simplified, controlled economic framework, making analysis more practical.
10. How does the production possibilities curve illustrate efficiency?
The production possibilities curve illustrates efficiency by showing all the possible combinations of goods that can be produced when an economy fully utilizes its resources. Points on the PPC represent efficient production levels because no additional output can be achieved without reducing the output of another good. If production occurs inside the curve, it signals underutilization or inefficiency. Thus, the PPC not only visualizes maximum possible output but also serves as a benchmark to measure productive efficiency in any economy or firm.
11. How can the production possibilities curve be used to show economic growth?
Economic growth is represented by an outward shift of the production possibilities curve. This shift shows that more of both goods or services can be produced than before due to increased resources or technological progress. The PPC’s movement outward indicates:
- Improvement in resource quantity and quality
- Advancement in technology
- Expansion of educational and human capital
A growing economy means new choices and higher living standards—the PPC visually demonstrates this by expanding the frontier of what’s possible to produce.
12. Why can the production possibilities curve be a straight line in some cases?
The production possibilities curve can be a straight line if the opportunity cost of producing each good is constant. This situation arises when resources are equally suited for producing both products, so shifting one unit from one good to another does not change the trade-off rate. In reality, this is rare, but it provides a useful starting point for simple models. The linear PPC shows that the law of increasing opportunity cost does not apply in these special cases, simplifying the illustration of resource allocation choices.
