Analysis on Korean Economy with an Estimated DSGE Model after 2000

Abstract

This paper attempts to search the driving forces of the Korean economy after 2000 by analyzing an estimated DSGE model and observing the degree of implementation regarding non-systematic parts of both the monetary and fiscal policy during the global financial crisis. Two types of trends, various cyclical factors and frictions are introduced in the model for an empirical analysis in which historical decompositions of key macro variables are quantitatively assessed after 2000. While the monetary policy during the global financial crisis have reacted systematically in accordance with the estimated Taylor rule relatively, the fiscal policy which was aggressively expansionary is not fully explained by the estimated fiscal rule but more by the large magnitude of non-systematic reaction.
