Suppose that the demand for real balances is (M / P)d = (5Y) - (20r). If the supply of real balances is 300, and the gross domestic product is 90, then the equilibrium interest rate is
Answer:
7.5
Step-by-step explanation:
Given that (M / P)d = (5Y) - (20r).
Where supply of real balances is 300
The gross domestic product is 90
Hence we have 300 = (5Y) - (20r)
Therefore, we have 300 = (5×90) - (20r)
=> 300 = 450 - 20r
=> 20r = 450 - 300
=> 20r = 150
=> r = 150 ÷ 20
=> r = 7.5
Therefore, in this case, the correct answer to the question is that the equilibrium interest rate is 7.5
