Section 1 - Instruction

You've mastered demand curves, supply curves, and elasticity! Now let's see the magic happen when supply and demand curves meet on the same graph.

This intersection point is called market equilibrium - where the market naturally settles.

What term describes the point where buyers and sellers meet in the market?

Section 2 - Instruction

Market equilibrium occurs where supply and demand curves intersect. At this point, quantity demanded equals quantity supplied - no shortages, no surpluses.

The price where this happens is called the equilibrium price. The quantity is called equilibrium quantity.

If demand is 100 units and supply is 80 units, is this equilibrium?

Section 3 - Instruction

Let's find equilibrium with real data. Coffee demand at $3: 200 cups. Coffee supply at $3: 200 cups. Perfect match!

At $4: demand is 150 cups, supply is 250 cups. At $2: demand is 300 cups, supply is 100 cups.

Which price creates equilibrium: $2, $3, or $4?

Section 4 - Instruction

When markets aren't at equilibrium, they naturally move toward it. If supply exceeds demand, prices fall. If demand exceeds supply, prices rise.

Think of it like water finding its level - markets find their equilibrium.

What happens to price when there's a shortage?

Section 5 - Instruction

Now for the exciting part: comparative statics! This means predicting how equilibrium changes when something shifts supply or demand curves.

Remember those curve shifters from previous sessions? They create new equilibrium points.

If coffee becomes trendy, which way does the demand curve shift?

Section 6 - Instruction

Let's trace through a demand shift. Coffee becomes trendy - demand shifts right. At the old equilibrium price, there's now excess demand.
