Study Notes

The IS-LM Model

Macroeconomics considers Gross National Product (GNP), money, and distribution
The IS-LM model is a balance between the real sector and monetary sector, considering supply and demand of all goods and services.
The model separates the economy into two sectors: real (national income, savings, investment, capital productivity, government spending, and taxation) and monetary (money supply, interest rates, and liquid cash balances).
The real sector's equilibrium condition is Savings (S) = Investment (I).
Investment is a function of interest rate (r) and National Income (Y), I = I(r, Y).
Savings is a function of interest rate (r) and National Income (Y), S = S(r, Y).
The IS curve shows the combinations of r and Y where S = I. It has a negative slope because lower interest rates encourage more investment and higher income encourages more saving.
The monetary sector's equilibrium condition is the demand for money (DM) equals the supply of money (SM): DM = SM.
The demand for money is a function of interest rate and national income, DM = L(r, Y).
The supply of money (SM) is controlled by the government.
The LM curve shows the combinations of r and Y where DM = SM. It has a positive slope because when income increases, the demand for money increases, resulting in a higher interest rate.
Combining the IS and LM curves gives a single equilibrium point (r*, Y*) where both the real and monetary sectors are in equilibrium.
The IS-LM model can be used to analyze the impact of changes in policy (fiscal and monetary) or exogenous factors on interest rates and national income.
Exogenous factors can be changes in saving rates, investment efficiency, or liquidity preferences.

Limitations of the IS-LM Model

The IS-LM model is a simplified representation of reality.
It does not account for all factors affecting the economy.
It ignores time lags.
It does not have a precise definition of money and struggles to accurately capture the current state of the economy.
