A Reuters market analyst (John Kemp) has created a stir by effectively declaring that the global economy is governed by some global NAIRU – a non-accelerating rate inflation rate of unemployment – such that the advanced economies cannot reduce their unemployment rates by expansionary fiscal policy and major structural reforms are needed. In a recent article – Mind the global output gap – he argues that “(e)scalating food and fuel prices are a sign the global economy is approaching full resource utilisation and the limits of sustainable output”. He claims that the “high unemployment and idle factories” in the advanced economies are not a sign of a “cyclical lack of demand’ but rather reflect “structural shifts”. From a policy perspective this is natural rate theory on a global scale and effectively denies that sovereign governments can influence domestic demand and real output (within their own policy boundaries) through aggregate demand management. This is the ultimate neo-liberal denial of the effectiveness of fiscal policy. It doesn’t stand scrutiny as you might expect.
