Accounting comparability among peer firms in the same industry reflects the similarity and the relatedness of firms’ operating environments and financial reporting. From the perspectives of “inherent audit risk” and “external information efficiency,” comparability is helpful for auditors in assessing client audit risk and lowers the costs of information acquisition, processing, and testing. I posit that the availability of information about comparable clients helps improve audit efficiency and accuracy. Empirical results show that comparability is negatively related to audit effort (surrogated by audit fees and audit delay). Moreover, comparability is negatively associated with the likelihood of audit opinion errors. These findings are robust to different specifications of regression models, particularly for the “endogeneity” issues due to the possible reverse causality that auditor style might influence client firms’ comparability. In sum, the study shows that accounting comparability enhances the utility of accounting information for external audits.

Earnings smoothing via accounting discretion could improve or garble actual earnings information. Although managers prefer a less volatile earnings path and perceive lower risk for earnings smoothness, prior studies show that there is no discernible relation between smoothness and firm valuation. Recent literature documents that socially responsible firms behave differently from other firms in their earnings management and financial reporting. We conjecture that the reported earnings of smoothers that are socially responsible deviate less from their permanent earnings, thus their reported earnings are more value relevant. Our empirical tests show income-smoothing firms with higher corporate social responsibility (CSR) experience higher contemporaneous earnings-return relationship, greater Tobin’s Q, and stronger current return-future earnings relationship. The results show that CSR is proved desirable as it adds a unique “quality dimension” to earnings attributes and is useful for firm valuation.

Recent microstructure research finds that liquidity risk, in particular its information component, plays an important role in explaining the post‐earnings‐announcement drift ( PEAD ). We decompose liquidity risk into an accounting‐associated component and a nonaccounting‐associated component and examine their relative importance in explaining PEAD . Our research is motivated by recent findings that liquidity risk is a systematic risk and earnings quality is negatively associated with liquidity risk. We find that the accounting‐associated component is more strongly related to PEAD returns than is its nonaccounting‐associated counterpart. Further analyses reveal that the relation between accounting‐associated liquidity risk and PEAD returns is weaker for firms with greater analyst following. We also find that in a significant market downturn, the relation between accounting‐associated liquidity risk and PEAD returns becomes more pronounced. Our study is the first to document a liquidity risk‐based role of accounting quality in explaining the PEAD phenomenon. It parses out the PEAD risk premia associated with accounting versus nonaccounting sources and, by so doing, sheds light on the role of accounting quality in shaping the liquidity risk‐ PEAD returns relation.

The engagement quality review is a key component of an audit firm's quality control system. This study leverages unique data on individual engagement quality reviewers (EQRs) to examine how previous shared working experience between EQRs and engagement partners affects audit quality. While prior research suggests that within‐firm network ties between predecessor and successor partners facilitate knowledge transfer, we find that prior shared working experience between EQRs and engagement partners is associated with lower audit quality. Mechanism tests indicate that such experience is associated with a higher likelihood of regulatory enforcement actions related to deficiencies in audit procedures, insufficient evidence, and a lack of professional skepticism. We also find that such experience corresponds with higher materiality thresholds, suggesting reduced scrutiny during audit planning and execution. Additional analyses reveal that these adverse effects primarily arise when previous shared working relationships did not produce adverse outcomes, when EQRs are not audit industry leaders, and when they face lower reputational risk. These findings are especially salient given that EQRs’ previous shared working experience with engagement partners appears to weigh heavily in EQR assignments. Overall, our study provides important insights into the implications of EQR independence and the determinants of engagement quality review effectiveness.

Exploiting a unique setting in China where internal controls are intended to manage risks, we investigate how internal controls shape the cash holding policies. Results show that firms with higher internal control quality (ICQ) are less likely to have abnormal cash holdings, either excess or deficit cash, and this effect is not driven by corporate governance quality. We also find that firms with higher ICQ are more likely to increase dividend payments and are less likely to increase M&A investments, especially when the firms have had a negative experience with prior M&A investments. Furthermore, our tests on the market valuation of cash holdings show that investors place a higher value on cash holdings of firms with higher ICQ. Collectively, our findings suggest that internal controls help companies shape reasonable cash policies that lead to value creation.

This study examines the role of information transparency in facilitating peer firms' investment in follow‐on innovation. We capture information transparency with both textual and numerical information disclosed in 10‐Ks. Using patent citations to proxy for investment in follow‐on innovation, we predict and find a positive association between transparency at the knowledge source and follow‐on innovation. We further show that the effect of information transparency varies with the degree of uncertainty around technological innovation. Thus, the evidence suggests that information transparency facilitates investment in follow‐on innovation by resolving uncertainty associated with investment in technological innovation. An analysis using the cited firms' going‐private decision as a negative shock to information transparency confirms the significant effect of a cited firm's disclosure on its decision to invest in follow‐on innovation. Our study contributes to the literature on the positive externalities of peer‐firm disclosures and highlights the important role of information transparency in shaping innovation investment decisions.
