We model cross-market Bitcoin prices as long-memory processes and study dynamic interdependence in a fractionally cointegrated VAR framework. We find (i) long-memory in both individual market and five-market systems depicting non-homogeneous informational inefficiency and (ii) a cointegration relationship with slow adjustment of shocks where uncertainty leaves a negative impact.

Using a sample of 1,632 U.K. firm‐year observations from 2002 to 2013, this paper investigates the impact of multidimensional corporate environmental performance (CEP) on firm risk. Considering two dimensions of CEP, namely environmental management performance (EMP) and environmental operational performance (EOP), we find that EMP serves as an effective mechanism in reducing firm risk, and such an effect is mainly driven by the manufacturing sector. Meanwhile, there is no clear association between EOP and firm risk. However, our findings highlight a moderating effect of EOP on the relationship between negative EMP and firm risk. This provides new insights into the value of multidimensional CEP and suggests that the complex relationship between outcome‐ and process‐based environmental performance is important for understanding the real effects of CEP on firm risk. Our results have important implications for managerial decision‐making in strategy and risk management, as well as for policymaking in environmental regulation.

This paper comprehensively examines the performance of a host of popular variables to predict Bitcoin returns. We show that time-series momentum, economic policy uncertainty, and financial uncertainty outperform other predictors in all in-sample, out-of-sample, and asset allocation tests.Bitcoin returns have no exposure to common stock and bond market factors but rather are affected by Bitcoin-specific and external uncertainty factors.

Research Question/Issue: We examine the role of corporate executives in dividend tunneling activity by controlling shareholders and whether the correlation between executive ownership and dividend tunneling is influenced by internal and external governance mechanisms.Research Findings/Insights: We find increased executive ownership may lead to a higher level of dividend tunneling. This is further strengthened by our finding that the positive effect of executive ownership on dividend tunneling is more pronounced for firms with weaker minority shareholder protection. In addition, our results show that higher degrees of state ownership may further intensify this positive association.Finally, we find that analyst coverage has a moderating effect and constrains the collusion between controlling shareholders and executives in dividend tunneling activity.Theoretical/Academic Implications: Our study contributes to the literature on the role of managerial ownership in controlling shareholders' dividend tunneling activity.We fill a gap in the literature on the corporate agency problem by providing evidence that dividends have been employed by controlling shareholders as a means of tunneling and that executives with higher ownership are more likely to collude with controlling shareholders in dividend tunneling activities.Practitioner/Policy Implications: This study contributes to the debates around the promotion of the cash dividend policy in China, as our findings show that cash dividends are used as a tunneling vehicle. Providing important evidence to regulators, our findings support the argument that external monitoring by financial analysts can effectively constrain dividend tunneling by dominant shareholders, especially in the context of emerging stock markets with high ownership concentration, weak minority shareholder protection, and an underdeveloped legal system.
