We compare two widely used pricing assumptions in the New-Keynesian literature: the Calvo and Rotemberg price-setting mechanisms. We show that, once trend in?ation is taken into account, the two models are very different. i) The long-run relationship between inflation and output is positive in...

Calvo pricing implies output gains, while Rotemberg pricing implies output losses after a disinflation. Introducing real wage rigidities has opposite effects: it generates a long-lasting boom in output in Calvo, and a moderate output slump in Rotemberg.

We study monetary policy in a New Keynesian (NK) model with endogenous growth and knowledge spillovers external to each firm. We find the following results: (i) technology and government spending shocks have different effects on growth; (ii) disinflationary monetary policies entail positive...

This paper analyzes the cost of disinflations under real wage rigidities in a micro-foundedNew Keynesian model. The consensus is that real wage rigidities can be a useful mechanismto induce the inflation persistence that is absent in the standard Calvo model...

When taken to examine disinflation monetary policies, the current workhorse DSGE model of business cycle fluctuations successfully accounts for the main stylized facts in terms of recessionary effects and sacrifice ratio. We complement the transitional analysis of the short-run costs with a...
