Topic: China's Model of Managing the Financial System

Speaker: Wei Xiong, Princeton University and NBER

Time: Wednesday, 26 February, 10:00-11:30 am Beijing Time

Location: Microsoft Teams Online conference room


China’s economic model involves active government intervention in financial markets. We develop a theoretical framework that anchors government intervention on amission to prevent market breakdown and volatility explosion caused by the reluctance of short-term investors to trade against noise traders. In the presence of information frictions the government can alter market dynamics by making noise in its intervention program an additional factor driving asset prices, and can divert investor attention toward acquiring information about this noise factor rather than fundamentals (as a result of complementarity in investors’ information acquisition). Through this latter channel, the widely-adopted objective of government intervention to reduce asset price volatility may exacerbate, rather than improve, information efficiency of asset prices.
