Is there any evidence of VAT related buoyancy effects in Greece?

This paper investigates the presence of buoyancy effects in VAT revenue. The projected improvement in economic conditions from 2014 onwards could result in cumulative gains in VAT revenue up to 0.70% of GDP in the period from 2014 to 2016. There is evidence that the intensification of VAT related audits and a likely shift in consumption patterns away from necessity goods (that are taxed at lower VAT rate) will further increase tax efficiency. The abovementioned factors can boost VAT revenue beyond what is currently expected, facilitating the achievement of future primary balance targets.
