When politicians use the term "stimulus" they usually mean the government's spending. For an economist, stimulus could also refer to spending however not every expenditure is "stimulus."
Why isn't every spending transaction taken into consideration as a "stimulus?" The way we analyze "stimulus" by looking at its effect, such as the amount of multiplier effect (additional dollars created by the initial expenditure) as well as the velocity effect (the speed at which money moves through the economy) and whether the impact is immediate. We also look at whether the money comes from existing revenue of the government or borrowing dollars, as both have distinct ancillary effects.
Additionally, not all "stimulus" is government spending; "stimulus" can be exactly the opposite: tax cuts. Tax cuts, similar to spending represents the use of the government's revenue. Through denying tax revenue, when tax cuts are made it encourages private sector spendingthat under the right circumstances could have critical immediate impact and substantial multiplier and velocity effects.
The differences in expenditure and their stimulating effect are very important. What is a simple example of spending which is immediate however has no potential for a multiplier or turn around effect? You are likely to drink five glasses a day.
Suppose as an "stimulus" the government paid you to drink an additional sixth glass of drinking water each day. It's a direct result of promoting the production of water as well as consumption. Once the glass of water has been consumed, there is no multiplier. All the government paid for was one glass of water beyond the norm, and in order to get the next glass of alcohol, the government needs to reimburse you another time. When the government stops paying for the additional drinking, it ceases. Since it does not promote consumption by you or other people, there is no effect of multiplier or velocity.
