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...

We introduce endogenous growth in an otherwise standard NK model with staggered prices and wages. Some results follow: (i) monetary volatility negatively affects long-run growth; (ii) the relation between nominal volatility and growth depends on the persistence of the nominal shocks and on the...

We study Ramsey monetary policy in a New Keynesian (NK) model with endogenous growth and knowledge spillovers external to each firm. We find that in contrast with the standard NK model, the Ramsey dynamics implies deviation from full inflation targeting in response to technology and government...

We analyze the implications for monetary policy when deficient aggregate demand can cause a permanent loss in potential output, a phenomenon termed as "output hysteresis." In the model, incomplete stabilization of a temporary shortfall in demand reduces the return to innovation, thus reducing...

Empirical evidence suggests that recessions have long-run effects on the economy's productive capacity. Recent literature embeds endogenous growth mechanisms within business cycle models to account for these "scarring" effects. The optimal conduct of monetary policy in these settings, however,...

We analyze the implications for monetary policy when deficient aggregate demand can cause a permanent loss in potential output, a phenomenon termed as output hysteresis. In the model, incomplete stabilization of a temporary shortfall in demand reduces the return to innovation, thus reducing TFP...

This paper analyzes conditions for determinacy in a new Keynesian model with endogenous growth. Endogenous growth shrinks the determinacy region considerably. Complying with the Taylor principle is not sufficient for determinacy, which decreases in the spillovers from actual on potential output....

This paper examines how the mechanism driving growth in the economy is likely to affect the optimal monetary policy response to shocks. We consider the Ramsey policy in a New Keynesian model in which growth is sustained by the creation of new patented technologies through R&D and we compare the...

This note presents an analysis which generalizes the results reached by Blackburn and Pelloni on the relationship between short-term stabilization policy and long-term growth by considering both deliberate (internal) and serendipitous (external) learning mechanisms for productivity growth

This paper studies fiscal policy in a New Keynesian DSGE model with endogenous technology growth in which scarring can occur endogenously through hysteresis effects in TFP. Both demand- and supply-driven recessions can weaken investment in R&D and technology adoption, thus depressing the...
