This paper investigates the gambling preference of Chinese investors in the convertible bond (CB) market through a natural experiment—the 2018 amendment of Article 142 of the Company Law. Utilizing CB issuance data from 2016 to 2023, we employ a cohort difference-in-difference approach and find a 4% to 7% increase in IPO premiums for high-repurchase-expectation CBs across various measures. This significant increase indicates that the legal revision reshapes investors’ expectation and adjusts their valuation of CBs. Furthermore, the event-study analysis reveals the escalating impact of legal revision, driven by the herding behavior of gambling investors.

We find a negative relation between share repurchase and corporate risk-taking using a sample of Chinese listed companies covering the period of 2014–2021. Our analysis yields consistent evidence even after consideration of endogeneity issues and the conducting of other robustness tests. We find that the impeded effect of share repurchase on corporate risk-taking is more pronounced for Chinese non-state-owned enterprises, firms with high competition in the product market, and firms located in low marketization regions. The possible mechanisms underlying these dynamics include share repurchase increasing the restrictions on low-cost financing and reducing over-investment. Our findings provide important implications for policyand low-making and are generalizable to other emerging markets.

Using sample of Chinese listed firms from Q1 2017 to Q4 2022, this article examines the impact of economic policy uncertainty on share repurchases. We find that economic policy uncertainty significantly increases the probability and scale of open market share repurchases. Private enterprises, government-supported enterprises, innovative enterprises, and investment hotspot enterprises repurchased more shares during periods of high economic policy uncertainty. Additionally, the market value of repurchase programs issued during periods of high economic policy uncertainty is larger. We also discover that economic policy uncertainty substantially influences the characteristics, timing, and outcomes of the repurchase programs. Lastly, this article confirms that share repurchase behavior has a similar effect to voluntary disclosures and can alleviate the information asymmetry triggered by economic policy uncertainty. In summary, Chinese listed firms have resorted to more share repurchases during periods of high economic policy uncertainty to convey their actual value and boost investor confidence, aligning with the signaling motive. Open market share repurchases surface as an efficacious instrument to cope with the risk from economic policy uncertainty.
