Not long ago, there lived an American economist who thought that it would be best to close down the Federal Reserve, the US central bank. A rather drastic view. What makes it particularly interesting is that it wasn’t voiced by some extremist, sidelined, unrecognised scholar. On the contrary. This view was held by Milton Friedman, one of the most influential economists that ever lived, a Nobel Prize winner economic counsellor to President Reagan.
Despite a zero interest rate the threat of falling prices is imminent, which hurts the economy rather badly. In a famous 2002 speech, former Fed chair Ben Bernanke proposed a conceptual solution to this very situation: as the printing press is a monopoly of the state, newly printed money should be injected into the economy, which will prevent deflation. Later on he also had the opportunity to do the stunt in practice.
