Empirical data show that firms tend to improve their ranking in the productivity distribution over time. A sticky-price model with firm-level productivity growth fits this data and predicts that the optimal long-run inflation rate is positive and between 1.5% and 2% per year. In contrast, the...

In the standard new Keynesian models, the optimal inflation rate is zero while the long-run inflation rate is non-zero positive in many countries. In this paper, we provide a new rationale for the non-zero trend inflation by utilizing the productivity gap between the intermediate-goods sector...

The paper estimates the NAIRU from a Phillips curve relationship in the state-space framework. To identify the inflation-unemployment trade-off we account for a time-varying inflation trend to control for the part of inflation that is not affected by the cyclical component of unemployment. In...

This paper investigates the relationship between the Great Moderation and two measures of inflation performance: trend inflation and inflation volatility. Using annual data from 1970 to 2011 for a large panel of 180 developed and developing economies, the results show that, as expected, both...

This paper explains the weak 'Phillips correlation' under low trend inflation.This correlation is confirmed empirically but the standard sticky price models fail to account for it. This paper extends the standard sticky price model to the case of the "smoothed off kinked" demand curve, which is...

This paper studies the welfare consequences of exogenous variations in trend inflation in a New Keynesian economy. Consumption and leisure respond asymmetrically to a rise and a decline in trend inflation. As a result, an increase in the variance of shocks to the trend inflation process...

This note proposes a full description of the Calvo price-setting model based on partial prices indexation and studies the interaction between partial indexation and trend inflation. We show that to use a hybrid version of the Phillips curve partly decreases the risks of overestimate due to the...

We provide new evidence on the fit of the hybrid Phillips curve based on indexation of prices to lagged inflation and trend inflation for the Euro area and the United States over the period 1970-2002. The GMM-West estimates suggest that (i) a full indexation scheme is not data consistent whereas...

This paper presents a new mechanism through which monetary policy rules affect inflation persistence. When assuming that price reset hazard functions are not constant, backward-looking dynamics emerge in the NKPC. This new mechanism makes the traditional demand channel of monetary transmission...

This paper proposes a new econometric framework for estimating trend inflation and the slope of the Phillips curve with a regime-switching model. As a unique aspect of our approach, we assume regimes for the trend inflation at one-percent intervals, and estimate the probability of the trend...
