| economics about gdp?
Does anyone know how the interest rate and the real gdp depending one on each other? Because I'm doing my homework and that what they ask me:
Consider the following money demand function:
M d = 500 - 20i
where M d is the quantity of money demanded (in billions of dollars), and i is the
interest rate in percentage. For example, i = 2 means the interest rate is 2%.
The supply of money is $400 billion.
The aggregate expenditure function in billions of dollars is
AE = 1000 + 0.8Y
a. Compute the equilibrium interest rate in the money market and find the
equilibrium real GDP.
I found that the equilibrium interest rate is 5%. Now I have to find the equilibrium real GDP, but I don't know how.
Please help
