• Demand & Supply Demand & Supply of a of a product determines the product determines the PRICEPRICE of a product!!!of a product!!!
• WhenWhen
• Demand = Supply Demand = Supply EquilibriumEquilibrium
• Demand ≠ Supply Demand ≠ Supply DisequilibriumDisequilibrium

Demand = Supply (Equilibrium Point)

Why the Equilibrium Changes?
–Change in Demand–Change in Supply–Change in Demand & Supply

When there is a shortage, producers
raise prices

S&D Analysis Practice
Analyze Hamburgers1. Price of sushi (a substitute) increases2. New cooking technology cuts production time in half3. Price of hamburgers falls from $3 to $1. 4. Price for beef triples (x3)5. Human fingers found in many hamburgers in McDonalds.
1. Before Change (Draw equilibrium) 2. The Change (S or D, Identify Shifter)3. After Change (Price and Quantity After)
