Consider the market for minivans. For each of the events listed here, identify which of the determinants of demand or supply are affected. Also indicate whether demand or supply increases or decreases. Then draw a diagram to show the effect on the price and quantity of minivans.

People decide to have more children.

A strike by steelworkers raises steel prices.

Engineers develop new automated machinery for the production of minivans.

The price of sports utility vehicles rises.

A stock market crash lowers people's wealth.

Consider the markets for film streaming services, TV screens, and tickets at movie theaters.

For each pair, identify whether they are complements or substitutes:

Film streaming and TV screens

Film streaming and movie tickets

TV screens and movie tickets

Suppose a technological advance reduces the cost of manufacturing TV screens. Draw a diagram to show what happens in the market for TV screens.

Draw two more diagrams to show how the change in the market for TV screens affects the markets for film streaming and movie tickets.

Suppose that the price of basketball tickets at your college is determined by market forces. Currently, the demand and supply schedules are as follows:

Draw the demand and supply curves. What is unusual about this supply curve? Why might this be true?

What are the equilibrium price and quantity of tickets?

Your college plans to increase total enrollment next year by students. The additional students will have the following demand schedule:

Price	Quantity Demanded
$4	4,000 tickets
8	3,000
12	2,000
16	1,000
20	0

Price	Quantity Demanded	Quantity Supplied
$4	10,000 tickets	8,000 tickets
8	8,000	8,000
12	6,000	8,000
16	4,000	8,000
20	2,000	8,000

Now add the old demand schedule and the demand schedule for the new students to calculate the new demand schedule for the entire college. What will be the new equilibrium price and quantity?
