1. Aggregate demand (AD) is the total demand for final goods and services in an economy at a given time.
AD = C + I + G + NX
2. Real money demand L(i,Y) = 8 - 2i + 0.5Y, Y = \$10 billion, real money supply MS = \$7 Billion.
L = MS, so:
8 - 2i + 0.5*10 = 7
The money demand formula is L = 8 - 2i + 5
3-What is the equilibrium (nominal interest rate?
L = MS, so:
8 - 2i + 0.5*10 = 7
2i = 6,
i = 3%
4. If the central bank increases the real money supply to \$4, the new interest rate will be:
8 - 2i + 5 = 4
2i = 9
i = 4.5%
