By Simon Wren-Lewis – Or maybe the middle ages, but certainly not anything more recent than the 1920s. Keynes advocated using fiscal expansion in what he called a liquidity trap in the 1930s. Nowadays we use a different terminology, and talk about the need for fiscal expansion when nominal interest rates are stuck at the Zero Lower Bound or Effective Lower Bound.
When monetary policy loses its reliable and effective instrument to manage the economy, you need to bring in the next best reliable and effective instrument: fiscal policy.
The Eurozone as a whole is currently at the effective lower bound. Rates are just below zero and the ECB is creating money for large scale purchases of assets: a monetary policy instrument whose impact is much more uncertain than interest rate changes or fiscal policy changes (but certainly better than nothing). The reason monetary policy is at maximum stimulus setting is that Eurozone core inflation seems stuck at 1% or below. Time, clearly, for fiscal policy to start lending a hand with some fiscal stimulus.
You would think that causing a second recession after the one following the GFC would have been a wake up call for European finance ministers to learn some macroeconomics. Yet what little learning there has been is not to make huge mistakes but only large ones: we should balance the budget when there is no crisis. more>
