''The gains from commitment when inflation persistence and data uncertainty coexist''
( 2011, Vol. 31 No.1 )
 
 
This paper investigates how the gains from commitment are large when inflation persistence and data uncertainty coexist. We consider two types of data uncertainty: measurement errors of potential output and inflation. We show that under a situation where data uncertainty exists, there are large gains from commitment as long as inflation is not extremely forward-looking or backward-looking. In particular, an increase in measurement error of inflation reduces the gains from commitment when forward-looking inflation is important, whereas there are large gains from commitment as long as inflation is not extremely backward-looking.
