‘The Austerity Con’ is the title of a recent article in the London Review of Books. It is written by a leading Keynesian economist Professor Simon-Wren Lewis, who is also a fellow of Merton College, Oxford. The article is available to non-subscribers here. It deserves to be widely read because it contains two important arguments against austerity.
The first argument nails the lie that austerity was necessary because of an immediate crisis of government funding. The second argument exposes the myth that austerity has been responsible for an improvement in government finances. Both of these arguments will be familiar to regular readers of SEB and Prof. Wren-Lewis will give them a far wider airing. Given that averting the crisis in government finances is offered by the supporters of austerity as its main justification, the title of his piece is fully justified.
However there is a difference of view among opponents of austerity about the nature of the current crisis. It is important because it underpins both the overall analytical framework and the suggested policy prescriptions. Prof. Wren-Lewis says, “The place to begin is 2009. By then the full extent of the financial crisis had become apparent.” He goes on, “The financial crisis was leading consumers and firms to spend less and save more. That made sense for individuals, but the problem was that because everyone was doing it, the total amount of demand in the economy was falling. As demand fell, firms produced less, so they reduced their workforce.”
This is not entirely accurate. Demand is comprised of two components, consumption and investment. By taking a step back to 2007 it possible to see more clearly how the crisis arose. Regarding the industrialised countries as whole grouped in the OECD it is possible to see that only one of these experienced a sharp fall. This was investment not consumption.
