Suppose the elasticity of money demand with respect to income is 2/3. If the money supply increases by 10% and output increases by 4.5%, while the real interest rate and the expected inflation rate are unchanged, then the price level increases by
A) 3%
B) 7%
C) 13%
D) 10%
Answer:
OPTION B: 7%
Reason:
Price elasticity = 2/3
= Percentage change in quantity.output/ percentage change in price
Since it is given that output increased by 4.5%
We can calculate the chnage in price level by putting this into th eformula of elasticity
2/3 = 4.5/x
x = 4.5/2*3
x = 6.75% or 7 % approximately
Hence, increase in price level is 7%
