• Supply is a curve or schedule that relates various quantities of an item that sellers will put in the market place at alternative prices, cp
• Therefore Supply expresses a relationship between Price and Quantity of Supply

LAW OF SUPPLY
• As Price Rises…
…Quantity Supplied Rises
• As Price Falls…
…Quantity Supplied Falls
A direct relationship exists between price and quantity supplied

• At equilibrium the firms are happyit is possible to sell all that can produce. At that Price consumers are happy because they are getting all they demand
• Above equilibrium is excess supply, and below is excess demand.

• Shifts in demand and supply cause the market equilibrium price to change and quantity to change.
• Demand decreases (left): both the price and quantity decrease
• Demand increases (right): both the price and quantity increase
• Supply decreases (Left): price increases and quantity decreases
• Supply increases (right): price decreases and the quantity increases
• To elimitate shortages and surpluses
• Shifts in demand and supply cause the market equilibrium price to change and quantity to change.

Problems to think aboutProblems to think about• Explain why supply curve has a positive
slope• Explain why an increase in number of
producers in a market causes the market supply curve to shift right
