[Verse 1]
Three ways to measure what the country makes
Expenditure counts what everyone takes
Income adds up what workers earn
Production shows what factories turn
GDP tells us how we're doing
Is the economy growing or just renewing
[Chorus]
Macro moves the whole world round
Supply and demand where growth is found
Fiscal spending, money supply
Watch the cycles rise and fly
From recession to expansion's peak
Macroeconomics is what we seek
[Verse 2]
Aggregate demand slopes down to the right
Higher prices make spending tight
Aggregate supply shows what firms will make
Short run sticky, long run's what it takes
Shifts move curves, movements slide along
Get the difference or you'll get it wrong
[Chorus]
Macro moves the whole world round
Supply and demand where growth is found
Fiscal spending, money supply
Watch the cycles rise and fly
From recession to expansion's peak
Macroeconomics is what we seek
[Verse 3]
Business cycles have four phases clear
Trough to peak then contraction's here
Leading indicators show what's coming next
Lagging follows, coincident's in the text
Employment, GDP, and sales we track
To see if the economy's on track
[Bridge]
Government spends to boost demand
Multiplier effects across the land
But Ricardian says we're not fooled
Future taxes leave us cooled
Deficit spending has its cost
Sustainability can't be lost
[Verse 4]
Central banks control the money flow
Open market ops make rates go low
Reserve requirements, discount rate
Quantitative easing when it's late
Money supply meets money demand
Interest rates help us understand
[Chorus]
Macro moves the whole world round
Supply and demand where growth is found
Fiscal spending, money supply
Watch the cycles rise and fly
From recession to expansion's peak
Macroeconomics is what we seek
[Verse 5]
Demand-pull inflation from too much cash
Cost-push prices rise in a flash
Phillips curve shows the trade-off game
Unemployment and inflation's claim
Expectations change the curve around
Natural unemployment rate is found
[Outro]
Frictional, structural, cyclical too
Different types of jobless blues
From micro choices to macro trends
The economic story never ends
Learn these concepts, make them stick
Macroeconomics does the trick
