House Prices and the Stance of Monetary Policy: The Case of Korea

This paper is an empirical investigation on whether the Bank of Korea should respond to the housing price developments in conducting monetary policy. For that aim, we construct a small scale empirical model of the Korean economy, simulate the estimated model with a set of alternative monetary policy rules, and compare the stabilization performances of those rules. There turns out to be ample room for further stabilization of inflation and output, if the central bank shifts from the historically conducted monetary policy rule to the optimal rule. The stabilization gains under the optimal rule, however, are not attributable to additional policy indicators (such as housing price inflation) the optimal rule involves. Rather, the optimal rule improves upon the historical one because the former takes a quite different reaction scheme toward the historical policy indicators. Moreover, as long as the Bank of Korea maintains appropriate reactions to the historical policy indicators, housing price inflation does not contain much extra information for further stabilization
