Questions about the end game for inflation over the next few years

The Reserve Bank's target is to maintain inflation between 1 and 3 percent.

Economist Cameron Bagrie says Treasury's forecasting inflation to average 4.1 percent over a five year period --- and we've been used to it averaging 2 percent for the past 30-odd years.

He says maybe the economic cost of getting inflation back down towards two percent...is too hard.

Bagrie says maybe two percent inflation is a little pie in the sky and as the economic costs become too hard to bear, we shift the inflation goalposts.
