What to Focus On

  • Supply = Quantity a producer is WILLING to sell at a given price over a time period
  • Supply is a 'desired' quantity — it reflects seller's intention, not actual sales
  • Supply always has a price reference — it changes as price changes

  • Stock = total quantity available for sale; Supply = part of stock offered at a specific price
  • Stock is a point-of-time concept; Supply is a period-of-time concept
  • Supply is always less than or equal to stock

  • Time-based types: Market Period (no change possible), Short Period (partial change), Long Period (complete change)
  • In market period, supply is fixed regardless of price changes
  • In long period, all factors of production can be adjusted

Common Mistakes to Avoid

Supply means the total quantity a producer HAS, not what they are willing to SELL.

A change in price causes a SHIFT of the supply curve (change in supply), not a movement along it.

Expansion of supply and increase in supply mean the same thing — both mean 'supply goes up'.

Memory Tips

Meaning of Supply — quantity offered for sale at a particular price and time
