In this article, we re-examine the causality between the stock returns and investor sentiment in China. The number of net added accounts is used as a proxy for investor sentiment. To mimic the different investment horizons of market participants, we use the wavelet method to decompose stock returns and investor sentiment into time series with different frequencies. Additionally, we test for nonlinear causal relationships based on Taylor series approximation. Our results indicate that there is a one-directional linear causality from stock returns to investor sentiment on the original series, while there is a strong bi-directional nonlinear causality between stock returns and investor sentiment at different timescales.

This article investigates the dependence structure between monetary policy and stock market liquidity in China. The dynamic 'symmetrized JC' copula copula is applied to capture evolving asymmetric behaviours and tail dependence. The empirical evidence shows that less liquid stock markets are influenced by contractionary monetary policy, and highly liquid stock markets are dependent on expansionary monetary policy. The asymmetric effect of monetary shocks on stock market liquidity is also found. The empirical results also indicate that the strength of lowertail dependence between monetary liquidity and stock liquidity rises significantly for the post-crisis period.

This paper examines how institutional characteristics of emerging economies influence the effect of controlownership divergence on market liquidity. We find that the divergence is negatively associated with liquidity and that this negative relationship is more pronounced in firms with more severe agency problems and information asymmetry. We argue that in an emerging market, the negative effect of the divergence on liquidity is worsened by state ownership and poorer shareholder protection, both of which result in more severe agency conflicts; we also find, however, that this effect is alleviated by the NTS reform, which aligns the interest of different shareholders. 2 control-ownership divergence on market liquidity.
