The Impacts of Policy Uncertainty on Asset Prices: Evidence from China’s Market

We employ the "Two Sessions," comprising the National People’s Congress and the Chinese People’s Political Consultative Conference, as a proxy for measuring policy uncertainty. In our analysis, we utilize a regression model, the three-path mediated effect framework, and the Campbell and Shiller decomposition method to delve into the influence of policy uncertainty on asset pricing within China’s financial market. Our findings reveal an increase in stock returns during the months leading up to the "Two Sessions," evident at both the market and firm levels. Notably, the extent to which stock returns respond to policy uncertainty is contingent on various firm-specific characteristics, including ownership structure, company size, and profitability. Furthermore, our investigation confirms that investor sentiment serves as a complete mediator in the relationship between policy uncertainty and its impact on asset prices. Additionally, we identify future cash flow as the primary conduit through which policy uncertainty directly exerts its influence on asset prices.
