Cyclical Deficit:
During a recession it is likely that there will be an increase in govt borrowing. This is because:
- Tax revenues will be lower.
- less people are working therefore income tax will be less
- Consumer spending is lower therefore VAT receipts are lower
- Government spending will increase
- More will be spent on unemployment benefits
- To increase AD fiscal policy requires higher spending and lower taxes

Relationship Between Output Gap and Government Borrowing

Note: A negative output gap means output is less than potential. This indicates spare capacity. A large negative output gap suggests the economy is experiencing a recession. This usually causes a rise in government borrowing.
Note: Government deficits can be indirectly financed by Central Banks buying up bonds, in a policy of quantitative easing.
