Individuals are never fully certain whether economic developments are persistent or temporary. This column shows that this permanent-transitory confusion has pervasive implications. It argues that the confusion injects the past into even purely forward-looking New-Keynesian frameworks, and shows empirically that inflationary forecasts indeed rely on past inflation.

Existing theoretical and empirical evidence suggests that less expansionary monetary policies lead to lower inflation and dampened inflation expectations. This column considers how the dispersion of inflation expectations can affect this relationship. The results show that an increase in the policy rate can give rise to higher inflation in the short run if professional inflation forecasts differ widely. These findings highlight the importance of considering the amount of agreement about inflation expectations in monetary policy decision-making.
