Quantity Demanded Inverse relationship between price and quantity demanded As prices decrease, quantity demanded increases (consumers are willing to buy MORE units of a good or service) As prices increase, quantity demanded decreases (consumers tend to buy LESS units of a good or service) PRICE causes a change in the number of units consumers wish to purchase Demand curve is downward sloping

Quantity Supplied Positive relationship between price and quantity supplied Quantity of a product that producers are willing and able to sell at any and all prices Sellers are interested in making a profit – 1. How much it will cost to produce? – 2. How much can the good/service be sold for? Supply curve is an upward sloping line

Equilibrium Market clearing price Supply and demand intersect – Most sellers are willing to sell at this point – Most buyers are willing to buy at this point A price above equilibrium causes a surplus (lower price) A price below equilibrium causes a shortage (increase price)

Determinants of demand 1.Tastes and Preferences 2.Number of buyers 3.Expectations 4.Price of related goods (substitutes and complements) 5.Income These factors will cause your demand curve to SHIFT. A shift to the right (increase); A shift to the left (decrease)
