We distinguish between the goods and services sectors in an otherwise standard unobserved components model of US inflation. Our main finding is that, while both sectors used to contribute to the overall variation in aggregate trend inflation, since the 1990s this variation has been driven almost...

How and under what circumstances can adjusting the inflation target serve as a stabilization-policy tool and contribute to welfare improvement? We answer these questions quantitatively with a standard New Keynesian model that includes cost-push type shocks which create a trade-off between...

Does raising an inflation target require increasing the nominal interest rate in the short run? We answer this question using a standard New Keynesian model with rich backward-looking elements. We first analytically show that the short-run comovement between inflation and the nominal interest...

I make inferences about complicated patterns of structural breaks in inflation dynamics. I extend Chib's (1998) approach by allowing multiple parameters such as the unconditional mean, a group of persistence parameters, and/or the residual variance to undergo mutually independent structural...

How and under what circumstances can adjusting the inflation target serve as a stabilization-policy tool and contribute to welfare improvement? We answer these questions quantitatively with a standard New Keynesian model that includes cost-push type shocks. Our proposed inflation target rule...

Would raising the inflation target require an increase in the nominal interest rate in the short run?We answer this policy question, first analytically in a small-scale New Keynesian model with backward-looking components where a closed-form solution exists, and then in a medium-scale model of...
