Historical Context
The concept of a production set has its roots in the broader field of production theory, which studies how goods and services are created. The development of the production set and the related production function was influenced by classical economists such as Adam Smith and later by neoclassical economists including Léon Walras and Alfred Marshall.
Definition and Explanation
A production set consists of all possible combinations of inputs and outputs that a firm or an economy can produce with existing technology. Mathematically, it can be represented as a set of points in a multi-dimensional space where each point corresponds to a particular combination of inputs and outputs.
- Production Function: The upper boundary of the production set, representing efficient input-output combinations. Points on this boundary are technologically efficient.
- Inefficiency: Points inside the production set are considered inefficient because more output could be produced with the same or fewer inputs.
- Convex Production Set: Represents a technology with non-increasing returns to scale, indicating that doubling the inputs will at most double the outputs.
Mathematical Representation
In mathematical terms, a production set \(P\) can be represented as:

D[Production Set]
D --- E[Efficient Frontier]
E --> F[Efficient Combinations]
D --- G[Inefficient Combinations]
Importance and Applicability
Understanding the production set is crucial for several reasons:
- Efficiency Analysis: Helps firms identify and move towards more efficient production processes.
- Economic Planning: Enables policymakers to understand the potential output of an economy and make informed decisions.
- Resource Allocation: Assists in optimal allocation of resources to maximize output and efficiency.
Examples
Consider a firm that produces two goods, \(A\) and \(B\), using labor and capital as inputs. The production set will include all feasible combinations of labor and capital that can produce varying quantities of \(A\) and \(B\). The efficient combinations lie on the production function, while any point inside the set represents inefficiency.
Related Terms
- Production Function: The functional relationship between inputs and outputs.
- Isoquant: A curve representing all combinations of inputs that yield the same level of output.
- Returns to Scale: The rate at which output increases as inputs are increased proportionally.
Comparisons
- Production Set vs. Production Possibility Frontier (PPF): While both concepts deal with production, the PPF represents maximum possible output combinations of two goods in an entire economy, whereas the production set pertains to feasible combinations for a single firm.
Interesting Facts
- The concept of the production set can be extended to multiple firms and even entire economies, providing a macroeconomic perspective.
- The production function can be non-linear, reflecting complexities in real-world production processes.
Inspirational Story
Consider the story of Toyota’s introduction of the Just-In-Time (JIT) production system. By optimizing the production set and focusing on efficient combinations of inputs and outputs, Toyota transformed from a small car manufacturer to a global leader in the automotive industry.

Proverbs and Clichés
- “Don’t put all your eggs in one basket.” (Regarding diversification in production inputs)
Jargon and Slang
- Lean Production: A methodology aimed at reducing waste within manufacturing systems.
- Bottleneck: A stage in production where the flow is limited or slowed down.
FAQs
Q1: What is a production set in economics? A: A production set represents all technologically feasible input-output combinations for a firm or an economy.
Q2: How does the production function relate to the production set? A: The production function forms the upper boundary of the production set, representing efficient combinations of inputs and outputs.
Q3: Why are points inside the production set considered inefficient? A: Because more output could be produced with the same or fewer inputs, indicating wastage of resources.
