A: Terrific question! Let's investigate.
There is a relationship between budget deficits and the health of the economy, but is certainly not a perfect one. There can be massive budget deficits when the economy is doing quite well - the past few years of the United States being a prime example.
That being said, government budgets tend to go from surplus to deficit (or existing deficits become larger) as the economy goes sour. This typically happens as follows:
- The economy goes into recession, costing many workers their jobs, and at the same time causing corporate profits to decline. This causes less income tax revenue to flow to the government, along with less corporate income tax revenue. Occasionally the flow of income to the government will still grow, but at a slower rate than inflation, meaning that flow of tax revenue has fallen in real terms.
- Because many workers have lost their jobs, their is increased use of government programs, such as unemployment insurance. Government spending rises as more individuals are calling on government services to help them out through tough times.
- To help push the economy out of recession and to help those who have lost their jobs, governments often create new social programs during times of recession and depression. FDR's "New Deal" of the 1930s is a prime example of this. Government spending then rises, not just because of increased use of existing programs, but through the creation of new programs.
