In other words, the size of multiplier is equal to 1/1- MPC = 1/MPC Thus, the value of multiplier can be obtained if we know either the value of MPS or MPS. If, for example, this ratio is greater than 1, machinery can be bought at one price and then generate output worth the larger amount that is reflected in its market value, giving positive economic profit.

Thus investment is everything that remains of total expenditure after consumption, government spending, and net exports are subtracted (i.e. In calculating the GDP expenditure approach, the formula of aggregate income (Y) equals to the sum of household consumption (C), business investment (I), government income (G), plus export (X) minus imports (M).

If we assume that our economy is a closed economy than we can find out calculate our investment spending by re-arranging our GDP equation such that: Which is actually exactly the same as our national savings formula. Thus, multiplier =∆Y/∆I =1/ 1-b equals marginal propensity to save (MPS) the value of investment multiplier is equal to 1/1-b = 1/s where s stands for marginal propensity to save. In an open economy.
