The effects of monetary policy: a DSGE model analysis of Taiwan

This article attempts to use empirical data to analyse the impact of monetary policy in a dynamic stochastic general equilibrium model. According to the monetary policy decisions of the Central Bank of China (Taiwan), maintaining price, financial stability and fostering economic growth are the ultimate goals of monetary policy during the empirical period. First, this article uses the cointegration tests to determine the operating targets, the intermediate targets and the ultimate goals of monetary policy. Then, a forward-looking aggregate demand–aggregate supply model for a small open economy is specified, and policy discretion is included in this model. Finally, the model is estimated by a linear state space model and is used to analyse the short-run effects of a systematic monetary change.
