Since the government collects an income tax on each transaction, the money introduced by the government spending is gradually withdrawn as it is re-spent. This "leakage" of money out of circulation places a limit on the total amount of spending and income that can ultimately arise. The eventual total level of aggregate income was shown to be a multiple, \(\frac {1}{\theta}\), of the initial government spend (where \(\theta\) is the tax rate). Here we'll consider what changes in this story when the population decide to save some of their income.
