Influence of dividend tax policy tied to investment horizon on stock price stability: Evidence from the 2015 dividend tax reform in China

Abstract

AbstractWe examine how the dividend tax cut policy tied to the investment horizon enforced on September 8, 2015, influences stock price stability in China's A‐share market. As the new dividend tax policy waives the tax on cash dividends for investors holding a stock for more than a year, it encourages long‐term investment behavior. From 2013 to 2017, we find that stock turnover, return volatility, and turnover volatility decrease after the policy enforcement, especially for stocks with high dividend yields. This result shows that dividend tax reforms increase investors' stock investment horizons and help stabilize the market. However, our findings demonstrate that stock crash risk increases after policy enforcement. Further analysis shows that earnings management through real activities manipulation for stocks with a higher dividend yield contributes to an increase in stock crash risk. Therefore, one externality of the dividend tax cut policy tied to the investment horizon is that top managers of firms with a higher dividend yield may take advantage of investors' passive longer‐term investment behavior and engage in more earnings management. This result suggests that regulatory agencies should pay attention to top managers' earnings management behavior after enacting policies that encourage long‐term investment.
