This paper examines the effect of trading on earnings management under the setting of China's non-tradable share reform. The government-enforced reform converted non-tradable shares to tradable and thus enabled blockholders and insiders to reduce holdings via public trading. We find significant increases in accruals among Chinese listed companies after the reform. The impact of the reform on earnings manipulations is increasing with the potential for share trading, the degree of information asymmetry and the intensity of stock selling by insiders and blockholders. Our findings support that trading by large shareholders and insiders significantly increases earnings manipulations.

This paper investigates the effects of shareholder protection law on corporate R&D investment. I find that the institutional protection of shareholder benefits reduces both underinvestment and overinvestment in R&D projects. Legal shareholder rights significantly increase R&D investment for firms that may underinvest, but reduce R&D for firms that may overinvest. Shareholder protection further enhances the growth of firms in R&D intensive industries, and promotes the economic growth of innovative countries. The results consistently show that enforcing stronger legal shareholder protection can help firms achieve an overall more efficient capital allocation to productive R&D investment.

We examine the influence of political connections on firms' environmental performance within the setting of China's Regulation 18, which prohibits government officials from taking business positions. Firms that lost political connections due to Regulation 18 experienced increases in environmental performance. This improvement is mainly driven by the tunneling channel rather than the sheltering channel. Specifically, we decompose the environmental ratings into strengths and concerns, and find the effect is stronger on strengths. The environmental improvements are more pronounced for firms with a higher degree of tunneling, and are value-enhancing. Our findings suggest that political connections impede firms' environmental performance and generate negative externality to the environment.

With superior information about their customers’ prospects, suppliers extend trade credit to capture future profitable business. We show that this information advantage generates significant return predictability. After controlling for major firm characteristics, firms that rely more on trade credit relative to debt financing have higher subsequent stock returns. The return predictability by trade credit is stronger among firms with lower borrowing capacity or profitability, and is more significant for firms with a higher degree of information asymmetry. Our findings suggest that trade credit extension reveals suppliers’ information that diffuses gradually across the investing public.
