At its simplest, Keynesian economics makes the case for the role of aggregate demand in determining output and employment in the economy as a whole. Government policies should therefore attempt to achieve low levels of unemployment through the management of aggregate demand, or the growth of expenditure. A crude form of this emphasises fiscal policy, the balance between tax revenues and public spending. A weak economy with rising unemployment may need an expansionary fiscal policy, with public spending increases or tax cuts to boost demand, while an overheating economy may need the opposite, to reduce demand and lower inflation.
This is a crude characterisation of a major school, or truthfully what has given rise to many schools, of economic thought. It is unfortunate since, in the wake of economic crises in recent decades, particularly that of 2008-09, commentators proclaimed the return of Keynesian ideas as governments across the world responded to recession with degrees of expansionary fiscal policy, as the use of monetary policy alone was deemed to be inadequate. But it didn’t last, and the turn to austerity and ‘tighter’ fiscal policy quickly followed. Alongside a return to reliance on monetary policy and the adoption of Quantitative Easing (QE), this played a role in the weakness of the recovery.
Following the global pandemic and the advent of war in Ukraine, many countries now face the prospect of stagflation, the combination of weak growth and rising unemployment alongside high inflation. Policymakers are now tightening monetary policy by raising interest rates, even as recent fiscal expansions come to an end. Crude Keynesianism appears to have little to offer, echoing its abandonment during the stagflation of the 1970s.
But genuine Keynesianism does have far more to offer public policy than expansionary fiscal policy during a deep recession. It may start with a focus on aggregate demand, but can be used to illustrate the importance of industrial policy, the reduction of inequality and the reform of the global monetary and trade system. This post intends to explain how. Continue reading
