The missing lowflation revolution: It will soon be eight years since the US Federal Reserve decided to bring its interest rate down to 0%. Other central banks have spent similar number of years (or much longer in the case of Japan) stuck at the zero lower bound. In these eight years central banks have used all their available tools to increase inflation closer to their target and boost growth with limited success. GDP growth has been weak or anemic, and there is very little hope that economies will ever go back to their pre-crisis trends.
Some of these trends have challenged the traditional view of academic economists and policy makers about how an economy works. ...
My own sense is that the view among academics and policy makers is not changing fast enough and some are just assuming that this would be a one-time event that will not be repeated in the future (even if we are still not out of the current event!).
The comparison with the 70s when stagflation produced a large change in the way academic and policy makers thought about their models and about the framework for monetary policy is striking. During those year a high inflation and low growth environment created a revolution among academics (moving away from the simple Phillips Curve) and policy makers (switching to anti-inflationary and independent central banks). How many more years of zero interest rate will it take to witness a similar change in our economic analysis?
