Supply curve (supply schedule) – Shows how much of the product that sellers are willing to sell at various price levels. Demand curve (demand schedule) – Shows how much of the product buyers are willing to purchase at various price levels. Equilibrium (market) price – The point at which the supply and demand curves meet. – The price at which producers are willing to sell their products and the price at which consumers will buy those products. Price Quantity Demand Supply

 On the island of Mocha, what was caused by the storm and the war?  Shortage of wood  What is a shortage?  When there is not enough of a product  What is a surplus?  When there is too much of a product

 Shortage  When supply of a good falls short of the demand.  A price below equilibrium results in a shortage  Prices increase  Surplus  When supply of a good exceeds the demand.  A price above equilibrium results in a surplus.  Prices decrease Price Quantity Demand Supply Shortage Surplus
