Economist Debates: Inflation: Statements: an increase in the target inflation rate would tend to undermine the rationale for central bank independence. Furthermore, it would constitute an additional movement away from recognition of the economic necessity for intertemporal discipline.

What does an increase in the target inflation rate from 2%/year to 4%/year possibly have to do with the rationale for central bank independence? How is a different inflation trend a thing that undermines the recognition of economic necessity?
