Study Notes

IS Curve

The IS curve summarizes the various combinations of the real interest rate and the level of real income that equilibrium in the goods and services market.
The IS curve shows the relationship between the real interest rate and the level of real income.

Effects of Government Spending and Real Interest Rate on IS Curve

An increase in government spending shifts the IS curve to the right.
A decrease in the real interest rate increases planned investment spending, leading to an increase in total planned spending and a shift to the right of the IS curve.
The equation for the IS curve is not provided.
A decrease in the real interest rate from r1 to r2 increases planned investment.
The real interest rate and investment spending have a negative relationship on the IS curve.

LM Curve

The Theory of Liquidity Preference is concerned with the demand and supply of money.
A reduction in cash usage due to Covid-19 safety precautions increases the demand for money, leading to an upward shift of the LM curve.
A decrease in real money demand shifts the LM curve to the right.
An increase in real interest rates leads to a decrease in the demand for money, shifting the LM curve to the left.

Effects of Interest Rate and Government Spending on Output

A decrease in the real interest rate leads to an increase in output.
An increase in government spending leads to an increase in output.

Effects of Interest Rate on Investment Spending

A fall in the interest rate leads to an increase in investment spending.
A decrease in the real interest rate leads to an increase in planned investment spending.

IS-LM Model

An increase in government spending has no effect on the LM curve in the IS-LM model.
A reduction in cash usage due to Covid-19 safety precautions has no effect on the IS curve in the IS-LM model.
An upward shift in the LM curve in the IS-LM model leads to an increase in investment spending.
