What is a Production Possibility Diagram?
A Production Possibility Diagram (PPD), also known as the Production Possibility Frontier (PPF), is a graphical tool used in economics to illustrate key concepts like scarcity, choice, and opportunity cost. It's a graph that shows all the possible combinations of two goods that can be produced with available resources and technology.
Imagine you run a small business making skateboards. There are two main types of goods to consider:
- 🪵 Capital Goods: The machines and tools needed to produce skateboards (e.g., wood shapers, drills, presses, workshop space).
- 🛹 Consumer Goods: The finished products you sell (skateboards).
Key Features of the PPD
- Production Possibility Frontier (PPF):
- The curved line on the diagram shows the maximum number of skateboards you can produce (consumer goods) considering the limitations of your workshop space and machinery (capital goods).
- As you use your tools and space to make more skateboards, it becomes trickier to squeeze in additional production. This reflects the trade-off between quantity and efficiency.
- Points on the PPF:
- Points on the curve represent situations where you are utilising your workshop and tools to their full capacity for a specific combination of capital goods (machinery) and consumer goods (skateboards). You are producing the most skateboards possible with your current setup.
- These are points A, B, C, D and F on the graph
- If you choose to allocate all of your resources to consumer goods, then you could produce at point A, but you won’t have any resources to allocate to your capital goods and vice versa
- Points Inside the PPF:
- These points show situations where you're not using your resources to their full potential. Maybe you are only producing a few skateboards a day – there's room for improvement! This area is like the "inefficient zone" where you could be making more skateboards.
- This is point E on the graph
- Points Outside the PPF:
- These points represent situations that are impossible with your current resources. You can't magically produce a hundred skateboards a day with your limited workshop space and machinery. These points fall outside the "attainable zone."
- This is point G on the graph
🛠️ Additional Considerations
PPF Shift: If you invest in more machinery or expand your workshop space (increasing capital goods), the PPF can shift outwards. This allows you to produce more skateboards (consumer goods) without sacrificing efficiency.
🚀 Economic Growth and the PPD
Did You Know? The PPF can help explain economic growth!
Economic growth refers to an increase in the economy's production capacity over time. This means the economy can produce more goods and services without necessarily using more resources.
It is usually measured by increases in real per capita Gross Domestic Product (GDP)/output per person by dividing GDP by the population.
PPD as a Starting Point: Shows the maximum combinations of goods an economy can produce with its current resources.
Economic Growth: Increase in production capacity, often measured by increases in real per capita GDP.
Economic growth is often depicted as a shift of the PPD outward. This outward shift signifies that the economy can now produce more of both goods (represented by the axes) simultaneously compared to before.
What are Factors that shifts the PPD outwards?
Reserves, fertile land, or improvements in resource extraction can expand the total resources available.
Technological Advancements: New technologies can make production more efficient, allowing for more output with the same amount of resources. Think of advancements in automation, robotics, or even better farming techniques.
- Example of technological advancements: Read this blog to see how farmers are deploying tech to boost yields and reduce waste using AI and machine learning! 👇
Improved Human Capital: A more educated and skilled workforce can be more productive, leading to increased output without additional resources.
Entrepreneurship and Innovation: New businesses and innovative ideas can lead to more efficient production methods and the creation of new goods and services, potentially expanding the overall production possibilities.
Bonus: What are factors that shift the PPD inwards?
These factors all limit an economy's ability to produce, making the PPD contract:
- ⛏️ Resource depletion (fewer resources to produce with)
- 🌪️ Natural disasters (damaging infrastructure and resources)
- ⚔️ War and conflict (diverting resources and disrupting production)
- 🏛️ Political instability (discouraging investment and growth)
- 📉 Decline in workforce skills (less efficient use of resources)
⚠️ NOTE: Moving along the PPF is different to shifting the PPF!
Shifting the PPF curve for example outwards, uses either more resources or resources of a greater quality. This reduces the opportunity cost of producing either capital or consumer goods, since more goods can be produced overall.
Moving along the PPF uses the same number and state of resources, and reallocates production from fewer consumer goods to more capital goods, for instance. This incurs an opportunity cost.

Technical Efficiency and Economic Efficiency
If you remember, in economies, we have the basic economic problem which refers to the scarcity of resources in relation to the unlimited wants and needs of individuals and society.
Therefore the challenge is to allocate these resources in the most efficient way possible to satisfy as many wants and needs as possible!
There are two main types of efficiency we need to grasp:
Technical Efficiency and Economic Efficiency. Both play a vital role in determining how well resources are utilised to produce goods and services.
💼 Economic Efficiency
Definition: Economic efficiency is achieved when the allocation of resources maximises the production of goods and services, and all waste is eliminated.
When we are efficient, we waste fewer resources and achieve better outcomes.
- This is important for individuals, businesses and society as a whole.
💡 Key Points
- Maximising Output: Achieving the highest production with the given resources.
- Minimising Waste: Using resources in the most efficient way.
- Importance: Improves outcomes for individuals, businesses and society.
📊 Understanding Economic Efficiency with a Production Possibility Diagram (PPD)
Imagine you are running a small business making hats and scarves. You have limited resources (fabric, machines, time) – that is scarcity! Let's use a PPD to explain economic efficiency 👇
Economic Efficiency Explained:
Point A on the PPD represents an economically efficient point. This means you are using your resources (fabric, machines, time) in the best possible way to produce hats and scarves.
- You are not wasting any resources, and you are at your maximum production capacity for this combination of goods.
Points Inside the Boundary (Inefficient):
- Any points inside the curved line (like point B) represent inefficient production.
- You are not using all your resources effectively. There is room to produce more hats or scarves (or both) without acquiring additional resources.
Points Outside the Boundary (Unreachable):
- Points outside the curve (like point C) are simply not possible with your current resources. You can't magically make more hats and scarves than your limitations allow.
Key Points to note from the Explanation:
💡Economic Efficiency (Point A): This is where all resources are allocated in the best way with minimal waste (like Point A on the PPD).
🚀Moving to Efficiency (No Opportunity Cost): Moving from an inefficient point (like B) to an efficient point (like A) does not involve an opportunity cost. You are simply using your resources more effectively.
⚙️ Technical Efficiency
Definition: Technical efficiency is about producing maximum output from minimum
input.
NOTE: Economic efficiency includes being technically efficient. Technical efficiency is a type of economic efficiency.
💡 Key Points
- Output Maximisation: Achieving the highest output with the given inputs.
- No Resource Waste: Utilising every bit of resource efficiently.
- Importance: Reduces costs and increases productivity.
Imagine you are running a lemonade stand with your friend. Here is how it applies:
Here are some more examples of Technical Efficiency:
🍋 A factory that optimises its production lines to minimise wasted materials and maximise the number of products made.
🌾 A farmer who uses the latest farming techniques and the right amount of fertiliser to get the highest crop yield from their land.
🏥 A hospital that streamlines its patient intake process to see more patients without compromising on basic care.
Importance of Technical Efficiency:
- Reduces Costs: Businesses that are technically efficient can save money by using their resources wisely and minimising waste.
- Increases Profits: By getting more output from the same amount of input, businesses can potentially increase their profits.
- Sustainable Practices: Technical efficiency can also contribute to sustainability by reducing the amount of resources needed to produce goods and services.
🤯Did you know that businesses using artificial intelligence like ChatGPT can improve employee performance by 66 percent?!
Artificial Intelligence (AI) is when computers are programmed to do things that usually need human intelligence. It is like teaching computers to think and learn on their own, like we do. AI helps computers understand language, recognise faces, drive cars, and lots more. It is like giving brains to machines!
AI is a good example of technical efficiency. How?
AI helps with automating processes, optimising resource use, and improving decision-making. It helps organisations to maximise output with minimal input, reducing waste and increasing productivity!

Technical Efficiency Explained with a Lemonade Stand:
- Making the Most Lemonade: You and your friend are technically efficient if you are using all your lemons, sugar, and water to make the most glasses of lemonade possible without anything going to waste. You are not slacking off or spilling ingredients!
- Using Resources Wisely: Technical efficiency focuses on the relationship between inputs (resources you use) and outputs (what you produce).
- In the lemonade stand example, your inputs are lemons, sugar, water, and your time. The output is the delicious lemonade you sell.
- Getting the Best Ratio: Minimising waste by finding the perfect balance between your inputs.
- You do not want to use too much sugar that your lemonade becomes syrup or too little water that it is too strong. You want to use the right amount of each resource to get the most lemonade possible.
- Not About the Best Quality: Focus on quantity: Technical efficiency is primarily concerned with getting the most output, not necessarily the highest quality.
- While you might strive to make the best lemonade ever, from a purely technical efficiency standpoint, just making the most lemonade with the resources you have is the goal.
