The case study presents an analysis of macroeconomic variables focusing on demand, private saving, and the government's fiscal deficit. The provided equations serve as the foundation for understanding the interplay between interest rates, savings, and government finances within an economy.
The government’s demand for funds is expressed by the equation \( I_d = 0.5r \), where \( r \) denotes the interest rate. Private saving \( S \) is represented as \( S = 1875 + 37.5r \), indicating that private savings increase with rising interest rates. The government’s deficit \( T - G \) is fixed at -175, implying that the government runs a surplus of 175 units, thus reducing the overall fiscal deficit or increasing national savings.
To determine the equation for national saving, one must consider both private saving \( S \) and the government’s surplus. Since \( T - G \) is a measure of the government’s savings (positive if surplus, negative if deficit), the total or national saving \( S_{national} \) can be derived as follows:
\[
S_{national} = S + (T - G)
\]
Substituting the given values:
\[
S_{national} = (1875 + 37.5r) + (-175)
\]
Simplifying, the equation for national saving becomes:
\[
S_{national} = 1700 + 37.5r
\]
Next, to find the new equilibrium interest rate, we recognize that equilibrium in the loanable funds market occurs where savings equals investment demand:
\[
S_{national} = I_d
\]
Setting the two equations equal:
\[
1700 + 37.5r = 0.5r
\]
Rearranging:
\[
1700 = 0.5r - 37.5r = -37r
\]
Solving for \( r \):
\[
r = -\frac{1700}{37} \approx -45.95
\]
A negative interest rate indicates that, under current conditions, the interest rate would tend toward a negative equilibrium, which is theoretically possible but practically unlikely. This suggests that the economy’s savings exceeds investment at all positive interest rates and that adjustments or policy interventions might be required.
To compute the values of national savings at this equilibrium interest rate:
\[
S_{national} = 1700 + 37.5 \times (-45.95) \approx 1700 - 1723.13 \approx -23.13
\]
This negative value implies a net dis-saving situation at this interest rate, which could signal an imbalance in the economy's savings-investment dynamics.
In conclusion, the analysis highlights key macroeconomic relationships: the derivation of national savings from private savings and government surplus, calculations of the equilibrium interest rate, and associated savings levels. The findings suggest that current fiscal and savings policies could be adjusted to stabilize the interest rate and promote sustainable economic growth.
