Abstract

We examine the different effects of monetary policy actions and central bank communication on China’s stock market bubbles with a Time-varying Parameter SVAR model. We find that with negative responses of fundamental component and positive responses of bubble component of asset prices, contractionary monetary policy induces the observed stock prices to rise during periods of large bubbles. By contrast, central bank communication acts on the market through expectation guidance and has more significant effects on stock prices in the long run, which implies that central bank communication be used as an effective long-term instrument for the central bank’s policymaking.

Summary

Introduction

The 2008 financial crisis and the high volatility of China’s stock market in recent years highlight the importance of financial stability. There have been limited studies on how different kinds of monetary policy instruments should react to it. The emergence of unconventional monetary policy has caused widespread concern among academia and industry, bringing the comparison of conventional and unconventional monetary policy on the table. Previous studies mention that transmission efficiency of conventional monetary policy is lower in developing than in developed countries because of the financial market incompleteness.
