David Smith sets us straight on this one:
One of the most enduring claims about the British economy in recent years is that the then coalition government abandoned austerity in 2012. It is a claim that gives comfort to those who see everything that has happened to the economy through the lens of fiscal policy. Only when austerity was abandoned in 2012, some argue, did the economy begin to recover. Unfortunately it does not fit the facts. It is a myth.
There are two elements to this. The first is the question of whether, in response to slower growth in the economy, or other factors, George Osborne abandoned his programme of fiscal consolidation.
The two foremost authorities on fiscal policy in Britain are the Institute for Fiscal Studies and the Office for Budget Responsibility. The IFS set out the position clearly after each budget and autumn statement during the last parliament. Chart 1.6 on p26 in its latest green budget, here, sets out the broad position. As it shows, consolidation continues through the parliament.
The IFS’s updated figures, published as part of its Election 2015 coverage, has the following sequence of numbers for the fiscal consolidation: 2010-11, 1.5% of GDP, 2011-12 2.3%, 2012-13 1.1%, 2013-14 1.5%, 2014-15 0.7%, 2015-16 0.6%, adding up to a cumulative fiscal tightening between 2009-10 and 2015-16 of 7.7% of GDP.
The OBR also addressed this, in its paper, Crisis and Consolidation in the Public Finances, here. Chapter 3 is the relevant chapter which, like the iFS, shows a programme of fiscal consolidation extending through the parliament. There was no abandonment of austerity.
There is more here, with other points of interest, hat tip goes to Chris Giles.
