UK Budget Deficit
A budget deficit occurs when government spending is greater than tax revenues, Therefore the government has to make up the shortfall by borrowing from the private sector.

The estimated PSNB for 2011/12 is £125bn - just under 10% of GDP

- 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
- A cyclical deficit is not necessarily a bad thing during a recession. If the government tried to balance the budget in a recession this would involve higher taxes and less spending reducing AD further.
