Normal business (No EOS)
Cost
Economy of scale

Market: Diamonds
• Factor # 1: new technology emerges to
make diamond mining more efficient
• Factor # 2: popular documentary shows
the enslavement of diamond miners
1.Construct a market graph and draw the
appropriate shifts in Supply & Demand
2.Explain what happens to price &
quantity?
Market: hamburgers
• Factor # 1: Price of corn used for feed drops
• Factor # 2: Reputable new study shows beef is
now healthy for you—refuting earlier studies
