Abstract
We develop a New Keynesian Phillips curve based on a combination of staggered price contracts and indexation to past inflation. This Phillips curve links current inflation dynamics to past inflation with a positive weight, as well as current and lagged expectations of inflation and output, giving a possible alternative explanation for recent empirical findings on the role of expectations in the determination of inflation
