Answer:
Suppose the economy is experiencing an output gap of –3%
a. Monetary policy or fiscal policy can be used to raise actual output toward potential output when:
The government can increase its spending or reduce taxes, which will shift the IS curve to the right and increase GDP.
The Fed can reduce the interest rate, which will shift the MP curve down and increase GDP.
b. The policies identified in part a,
can be used together to raise actual output toward potential output.
Explanation:
Investment-Savings (IS) curve shows all the levels of interest rates and output (GDP) at which an economy's total desired investment (I) equals its total desired saving (S). This equilibrium can be achieved at a level of interest rate that maximizes output. The IS curve slopes downward, and to the right because at a lower interest rate, investment is higher, which produces more total output (GDP) for the economy.
