Price level is fixed & Fed increases money supply by 10% to $2.2 trillion

How much does the GDP increase or decrease?

### 1 Answer | Add Yours

The quantity theory of money states that:

Money supply*Money velocity = Price Level*Quantity

Price level*Quantity = real GDP

Therefore, assuming that the price level is fixed and the money velocity is fixed, real GDP will increase by 0.2 trillion or $200 billion. Here is the math:

2.2 trill / 1.1 = 2 trill (how much we started with)

2.2 trill - 2 trill = 0.2 trillion
