On January 4th 2011, the standard rate of value added tax (VAT) jumped from 17.5% to 20%. For the first time, the UK VAT rate is now the same as the basic rate of income tax! Prime Minister David Cameron has stated publicly that the rise in VAT is likely to be permanent rather than temporary. The UK economy will thus have to adjust to this higher rate but what are some of the possible macroeconomic consequences?
