The
economy of a country is represented by the model below:
Goods
Market:
++
Consumption function: C = 15,000 + 0.75(Yd)
++
Investment function: I = 5,000 – 50i
++
Government expenditures: G = 5,000
++
Export function: X = 5,000
++
Import function: M = 1,000 + 0.1Y
++
Taxes: T = 1,000 + 0.1Y
Money
Market:
++
Money Supply: Ms = 30
++
Money Demand (Transaction): Mdt = 0.25Y
++
Money Demand (Asset): Ma = 2,000 – 20i
(Yd =
disposable income & Y = level of output in the economy, R =
interest)
a)
Calculate the equilibrium level of output and the equilibrium level
of interest for this economy.
b)
Please sketch diagrams illustrating the equilibrium.
c)
Assume that the money supply DECREASES. Illustrate and explain the
effects in both markets.
d)
Assume that the exchange rate APPRECIATES. Illustrate and explain
the effect in both markets.
