Answer:
a) 2000
b) 4000
c) 2000 and 4800
Explanation:
The quantitative theory of money shows how the monetary side of an economy behaves, that is, the effect of money supply on income. It is given by the equation MV = PY, where M = money supply, V is the currency's velocity, P is the price level and Y is the real income level.
M = 500, V = 8, P = 2
a) The real income level:
MV = PY
500 x 8 = 2 x Y
Y = 2000
b) Nominal income level (price level multiplied by real income)
PY
2 x 2000 = 4000
C) If the money supply increases by 20%, ie to 600, the real income will be:
MV = PY
600 x 8 = 2.4 x Y (Y is full employment income, so the effects of money supply will be on the price level)
Y = 2000 Real income remains the same, increase in money supply does not affect real output, only price level, which increases from 2 to 2.4.
The nominal income, in turn, will be:
PY
2.4 x 2000 = 4800
That is, an increase in the money supply only increases nominal income.
