Q: What is the consumption function?
A: The consumption function describes how consumption depends on disposable income:
C=C(Y−T)
C=C(Y−T).
Q: What is the investment function?
A: The investment function describes how investment depends on the interest rate:
I=I(r)
I=I(r).
Q: What is the difference between nominal and real interest rates?
A: The nominal interest rate is the stated rate, while the real interest rate adjusts for inflation:
r=i−π
r=i−π.
Q: What is the role of financial markets in the economy?
A: Financial markets balance savings and investment, determining the equilibrium interest rate.
Q: What happens to investment when government spending increases?
A: Investment decreases due to the crowding-out effect, as higher government spending raises interest rates.
The consumption function describes how consumption depends on disposable income:
C=C(Y−T)
C=C(Y−T).
The investment function describes how investment depends on the interest rate:
I=I(r)
I=I(r).
The real interest rate adjusts the nominal interest rate for inflation:
r=i−π
r=i−π.
Financial markets balance savings and investment, determining the equilibrium interest rate.
Increased government spending leads to higher interest rates, which reduces private investment.
