Monetary Policy in a New Keynesian Model with Endogenous Growth

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 effects on growth; (iii) the optimal long-run inflation rate is zero; (iv) the Ramsey dynamics implies deviation from full inflation targeting in response to technology and government spending shocks; (v) the optimal operational rule is backward looking and responds to inflation and output deviations from their long-run levels.
