Budgetary Deficit: A Flow Concept
Understanding Deficits in Economics
In economics, a deficit is generally considered a flow concept.
A flow refers to a quantity measured over a period of time. Think of it like water flowing through a pipe; we measure how much water passes in a minute, an hour, or a day.
Similarly, a deficit is calculated over a specific fiscal period, such as a financial year (e.g., April 1st to March 31st).
Flow vs. Stock Concepts
Flow concepts are contrasted with stock concepts.
A stock refers to a quantity measured at a particular point in time. It's like a snapshot. For example, the total amount of water in a tank at a specific moment is a stock.
Example of a Stock Concept: National debt is a stock concept. It represents the total accumulated borrowing of a government at a particular point in time.
Deficit in the Context of Budgets
When we talk about a government's deficit (like a budget deficit), we are referring to the difference between its total expenditures and its total revenues over a given fiscal year.
For instance, if a government spends $100 billion and earns $80 billion in a fiscal year, it has a $20 billion deficit for that year. This $20 billion is the 'flow' of the deficit during that period.
The opposite of a deficit is a surplus, which also is a flow concept, representing excess revenue over expenditure in a given period.
