Monetary Policy in Estimated Models of Small Open and Closed Economies

This paper compares monetary policy effects in New-Keynesian models of small open and closed economies fit to Canada. A monetary policy rule allows the central bank to systematically manage the nominal interest rate in response to inflation, output, and money growth variations. The structural parameters of a small open-economy (SOE) and a closed-economy (CE) models are estimated using a maximum-likelihood procedure with a Kalman filter. Estimation results show that the SOE and CE models lead to qualitatively similar estimates for the Canadian economy. Also, the effects of monetary policy shocks, and of other domestic shocks, generated in the SOE model resemble to those generated in the CE model. In addition, the forecast-error decomposition shows that foreign shocks account for small fractions of the variability observed in Canadian macroeconomic variables.
