Should central banks’ inflation targets be raised?

Is a target of 2% actually superior to one of 3% or 4%, for instance, or does it merely owe its exalted status to tradition? 

The relative damage done by extremely high or accelerating price growth may be easily visible, but economists have struggled to identify differences in the costs to an economy from different stable, low-single-digit inflation rates. 

If the costs of a slightly higher inflation target are small, the benefits are potentially sizeable. Chiefly, it could help central bankers avoid the so-called zero lower bound on nominal interest rates
