Elasticity of supply shows how sensitive producers are to a change in price. The elasticity of supply is based on time limitations. Essentially, similar to how customers respond to price changes, producers need time to produce more.

  1. Elastic Supply:
    • Producers are highly responsive to price changes.
    • The supply curve is flatter.
    • Typically applies in the long-run, as producers have more time to adjust
    • For example, manufactured goods like cars or electronics.
  2. Inelastic Supply:
    • Producers are less responsive to price changes.
    • The supply curve is steeper.
    • Common in the short-run, when production adjustments are limited.
    • For example, agricultural goods (e.g., crops) during a growing season.
  3. Perfectly Inelastic Supply:
    • Quantity supplied does not change, regardless of price.
    • Represented by a vertical line.
    • For example, fixed supply goods, like unique artworks or land in a specific location.

Perfectly inelastic is when the Q doesn’t change (vertical line) and perfectly elastic is a horizontal line. See:

Determinants of Elasticity of Supply

  1. Time Horizon:
    • Short-Run: Supply is usually inelastic due to limited production flexibility.
    • Long-Run: Supply becomes more elastic as firms can adjust resources and production.
  2. Flexibility of Production:
    • Goods that can be produced quickly and cheaply are more elastic.
    • For example, t-shirts vs. heavy machinery
  3. Availability of Inputs:
    • Easy access to raw materials makes supply more elastic.
    • For example, abundant wood supply allows quick production of furniture.
  4. Storage Capabilities:
    • Goods that can be stored are more elastic since producers can respond to price changes by releasing inventory.
    • For example, non-perishable goods like canned food.
