Instructions:
MS
1. Label equilibrium price as old price to consumer/producer and
equilibrium quantity as old quantity with dotted lines and labels.
2. Choose 3 points on supply curve: one near the bottom of the
supply curve (Huey), one at equilibrium (Dewey) and one near
the top of the supply curve (Louie).
3. Draw an arrow down from each point by the dollar amount of
the subsidy (use price scale), marking points at the bottom.
4. Sketch a new curve through these points and label it MS1.

6. At the new equilibrium draw a dotted line across to the price

axis and label this “price consumer pays” (P ).

7. At the new equilibrium, draw a dotted line up to the old supply
curve and then across to the price axis and label “price
