The Effect of Board Independence on Information Asymmetry

Boards have an important role in ensuring that investors’ interests are protected. Our paper first examines whether the independence of a firms board affects information asymmetry among investors. We provide evidence that greater board independence leads to lower information asymmetry. Next, we provide evidence that more voluntary disclosure and greater analyst coverage are two underlying mechanisms via which greater board independence reduces information asymmetry. Of the two mechanisms, we find that analyst coverage is more significant in influencing how board independence affects information asymmetry. Overall, our paper contributes to a better understanding of the effect of board independence on information asymmetry.

Tax Aggressiveness and Auditor Resignation

We examine the relation between client tax aggressiveness and auditor’s resignation decision. Consistent with the agency view of tax avoidance which suggests that client tax aggressiveness can increase litigation and reputational risk to auditors and increase the potential conflict with managers, we find a positive association between our proxies for tax aggressiveness and the likelihood that an auditor resigns from an audit engagement. Further, this association is stronger when external monitoring of the client firm is less effective, when there is greater potential for agency problems in the client firm, and when the economic importance of the fees received from the client firm is lower. Overall, our study identifies client tax risk as an important determinant of auditors’ resignation. This result should be of interest to auditors who actively manage client audit risks and to tax authorities who have incentives to identify firms with abusive tax reporting behavior.

Corporate Tax Aggressiveness and Managerial Rent Extraction: Evidence from Insider Trading

We examine the association between corporate tax aggressiveness and the profitability of insider trading under the assumption that insider trading profits reflect managerial opportunism. We document that insider purchase profitability, but not sales profitability, is significantly higher on average in more tax aggressive firms. We also find that the positive association between tax aggressiveness and insider purchase profitability is attenuated for firms with more effective monitoring and is accentuated for firms with a more opaque information environment. In addition, we provide empirical evidence that tax aggressiveness is significantly associated with greater insider sales volume in the fiscal year prior to a stock price crash. Finally, we find that the association between tax aggressiveness and insider purchase profitability weakens after the introduction of FIN 48, consistent with the increased transparency of tax positions under the new disclosure requirement reducing insiders’ information advantage and hence their ability to profit from insider trading. To the extent that insider trading profits reflect managerial opportunism, our results are consistent with managers exploiting the opacity arising from tax aggressive activities to extract rent from shareholders, particularly those who sold their shares to the managers. Our findings are particularly important in light of the number of studies relying on the agency view of tax avoidance to develop arguments or to draw inferences.
