Historical Context
The concept of supply elasticity is rooted in classical economics and has been discussed since the 19th century. Notable economists like Alfred Marshall and Léon Walras contributed significantly to the formalization of supply and demand theories, which include the elasticity of supply.
Types/Categories
- Perfectly Inelastic Supply (Elasticity = 0): Quantity supplied does not change at all with changes in price.
- Relatively Inelastic Supply (Elasticity < 1): Quantity supplied changes, but by a smaller proportion than the price change.
Key Events
- Marshallian Demand Theory (1890s): Alfred Marshall introduced the concept of elasticity of supply in his seminal work “Principles of Economics”.
- Development of General Equilibrium Theory: Léon Walras and other economists developed models illustrating how markets with inelastic supply function in equilibrium.
Detailed Explanations
In economics, the elasticity of supply measures how the quantity supplied of a good or service responds to changes in its price. Specifically, inelastic supply refers to situations where the elasticity of supply is less than 1. This indicates that a percentage increase in price results in a smaller percentage increase in quantity supplied.
Mathematical Formulas/Models
The formula for price elasticity of supply (Es) is:
If \(E_s < 1\), the supply is considered inelastic.

Importance and Applicability
Understanding inelastic supply is crucial for:
- Policy Makers: Making informed decisions on regulations and taxes.
- Businesses: Planning production and pricing strategies.
- Investors: Assessing market opportunities and risks.
Examples
- Agricultural Products: Due to factors like growing seasons and land availability, agricultural products often have inelastic supply.
- Utilities: Supply of services like electricity and water tend to be inelastic due to infrastructure constraints.
Considerations
- Production Capacity: Firms may have limited capacity to increase production in response to price changes.
- Market Entry Barriers: High barriers can prevent new firms from entering the market easily, leading to inelastic supply.
Related Terms with Definitions
- Elastic Supply: A situation where the elasticity of supply is greater than 1.
- Unitary Elastic Supply: Supply elasticity equals 1, meaning the percentage change in quantity supplied equals the percentage change in price.
Comparisons
- Elastic vs. Inelastic Supply: In elastic supply, quantity supplied changes significantly with price changes. In inelastic supply, quantity supplied changes little with price changes.
Interesting Facts
- Historical Agricultural Crises: Past food shortages have highlighted the inelastic nature of agricultural supply.
Inspirational Stories
- Ford’s Assembly Line: Revolutionized production but initially faced inelastic supply issues due to limited infrastructure and technology.

Summary
Inelastic supply is a fundamental concept in economics that describes a situation where the quantity supplied responds minimally to price changes. This condition is influenced by factors such as production capacity and market barriers. Understanding inelastic supply is essential for policymakers, businesses, and investors for making informed decisions and strategies.
