Ultra low interest rates have led many to conclude that monetary policy can no longer be relied upon to underpin the world economy. Governments should boost spending and cut taxes without worrying about the deficit until after inflation picks up.
If governments follow this advice, growth should accelerate, boosting stock markets. If inflation were to stay low, all well and good. If not, then interest rates can be raised.
Amongst economists, the most extreme proponents of fiscal policy are advocates of “Modern Monetary Theory” (MMT), several of whom are now serving as economic advisers to Democrat politicians in the United States. MMT argues that a country that issues its own currency cannot run out of money and therefore does not need to worry about the path of government debt. Instead of quantitative easing (QE) being used to buy government debt, it should be used to finance government spending. If inflation did eventually rise, higher taxes could be used to rein in spending and cool price pressures. Given that massive doses of QE by the world’s leading central banks have failed to generate much inflation since the global financial crisis, there is an implicit hope that inflation might stay low.
As an indicator of the change in the intellectual climate, central bankers, such as the outgoing President of the European Central Bank, Mario Draghi, have advocated fiscal expansion in Europe; the former head of the US Federal Reserve, Ben Bernanke, has done so in the US. Even the International Monetary Fund, the world’s fiscal steward, has advocated fiscal expansion, albeit only for a select group of countries like Germany and South Korea.
