Short Description: Supply and demand, voiced by the market itself, over a funk groove that mirrors the push-and-pull of buyers and sellers.

Includes price floors, ceilings, and deadweight loss. Economics that grooves.

Lyrics:

I am the market.
I never sleep.
I balance the buyers,
I balance the sheep.

The Law of Demand - price goes up, quantity falls.
Price goes down, the buyers run through the malls.
Inverse relationship, that's the demand curve slope.
Downward to the right. That's how the buyers cope.

The Law of Supply, price goes up, quantity grows.
Sellers want more profit, that's how the market flows.
Direct relationship, that's the supply curve climb.
Upward to the right. The sellers chase the dime.

Where they cross - that's where the magic happens.
Where they meet - that's where the market relaxes.
Quantity demanded equals quantity supplied.
Equilibrium - the market-clearing tide.

I am the invisible hand.
I push the price up, I pull it down, that's the plan.
Surplus above, shortage below.
The market always finds the flow.
Demand meets supply, that's where I stand.
I am the invisible hand.

Now learn the shifters, what makes the curves move.
Demand has five to throw you out of your groove:
Income, tastes, and numbers, what the future implies,
And the price of related goods that can swing high.

Income goes up, demand for normal goods shifts right.
Inferior goods shift left when the wallet feels light.
Supply has six: technology, inputs, the count of firms,
Taxes, expectations, alternative terms.

Tech improves, supply curve shifts right.
Input prices climb — supply pulls back tight.
Hear me close, here's the trap they'll set:
A shifter moves the curve, don't you forget.

But a price change only moves you along
same curve, different point. Sing the right song.

Where they cross, that's where the magic happens.
Where they meet, that's where the market relaxes.
Quantity demanded equals quantity supplied.
Equilibrium, the market-clearing tide.

I am the invisible hand.
I push the price up, I pull it down - that's the plan.
Surplus above, shortage below.
The market always finds the flow.
Demand meets supply - that's where I stand.
I am the invisible hand.

Price too high, surplus on the floor.
Sellers can't move it. They lower at the door.
Price too low, shortage at the gate.
Buyers bid it up. The price escalates.

Then there's the floors and the ceilings of the state:
Floors keep things UP, surplus is the fate.
Ceilings keep things DOWN, shortage at the line.
Binding price controls, they break the design.

Floor above, ceiling below, that's how they bind.
Any other way, they leave no mark behind.
Deadweight loss when the trades can't clear.
The market mourns the deals that disappear.

I am the invisible hand.
I push the price up, I pull it down - that's the plan.
Surplus above, shortage below.
The market always finds the flow.
Demand meets supply, that's where I stand.
I am the invisible hand.

I am the market.
I never sleep.
I balance the buyers,
I balance the sheep.
