Towards a “Keynesian” world: What consequences?
Major countries’ economic policies are becoming more and more Keynesian: the Biden administration wants to increase public spending on healthcare, education, infrastructure and energy transition; the euro zone and the United Kingdom have implemented a recovery plan focused on energy transition and digital development; in China, Japan, fiscal deficits have been increased due to public investment. What should we look at when the world becomes “Keynesian”? First, that the fiscal deficit does not exceed the ex ante excess of private savings over investment; if it does, real interest rates will rise; Second, the nature of government spending, to see whether it can be expected to raise potential growth .
