Empirical data indicate that firms tend to have below-average productivity upon entry and that they tend to experience post-entry productivity growth. I present a New Keynesian model with growth in firm-specific productivity and firm turnover that captures these two phenomena. The model predicts...

Empirical data show that firms tend to improve their ranking in the productivity distribution over time. A stickyprice 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...

Empirical data suggest that new firms tend to grow faster than incumbent firms in terms of their productivity. A sticky-price model with learning-by-doing in new firms fits this data and predicts that for plausible calibrations, the optimal long-run inflation rate is positive and between 0.5%...

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...

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 argument made in this manuscript is that the two traditional macroeconomic tools, fiscal policy and monetary policy, are insufficient to bring back efficiently into equilibrium an economy that has had a major crisis. Both traditional macro-tools only work through the demand side, and there...
