Significance of Price Elasticity of Supply
Significance of Price Elasticity of Supply (PES)
PES shows how quickly and easily producers can increase supply when the price of a product rises. A high PES (elastic supply) is usually better for firms because it helps them respond fast to market changes.
Why firms prefer high PES
It helps them stay competitive in the market.
They can earn more revenue and profit when prices rise.
Firms can increase PES by:
Having spare capacity
Keeping large stock levels
Using better storage systems
Upgrading to modern technology
Improving distribution systems
Training workers to increase labour mobility
When PES is low (Inelastic supply)
If supply is inelastic, firms cannot increase output quickly. So when demand rises:
Prices go up a lot
Firms get higher profit margins
But it may not help the whole economy, especially if foreign competitors can supply more easily
Government interest in PES
Housing market:If housing supply is inelastic, prices rise sharply when demand increases.This makes houses expensive and increases the wealth gap.Governments may intervene to ensure affordable housing.
Labour market:Low PES in labour supply can cause labour shortages and high wages.Governments may allow migrant workers to increase labour supply and make the market more responsive.
