Our findings indicate that the People＇s Bank of China responded to inflation and output changes, but did not react to asset price fluctuations during the period from January 1997 to March 2010. The optimal monetary responses to exogenous shocks are also examined It is revealed that using asset prices to formulate monetary policy would not help to improve monetary authorities ＇performance in lowering the volatilities of output growth and inflation while keeping output growth and inflation in their safety zones. The effectiveness of monetary policy and fiscal policy in reacting to external shocks is also discussed.展开更多
