Explanation:
The multiplier is calculated by two marginal decisions by firms and individuals. A firm can decide whether to save the revenue or to consume it, therefore there is marginal propensity to consume and marginal propensity to save as options for both firms and individuals. Therefore, the size of the multiplier which is applied to a change in AD is dependent upon size of the marginal propensity to consume and marginal propensity to save.
