We examine the effects of the 1998 merger of Price Waterhouse ( PW ) and Coopers & Lybrand ( CL ) on the audit quality of the merged firm PricewaterhouseCoopers (PwC) at both the firm and office levels, where audit quality is surrogated by the auditor's propensity to issue a going‐concern opinion, clients’ likelihood of meeting or beating analysts’ earnings forecasts, and clients’ accrual quality. At the firm level, we find that the merger increased audit quality for PwC relative to the audit quality of the other Big N firms. At the office level, our findings, albeit mixed, collectively suggest that the improvement in firm‐level audit quality was likely driven by the improvement in audit quality at PwC's overlapping offices, that is, offices in cities where both PW and CL had separate offices prior to the merger. Further, our findings suggest that although the PW / CL merger increased auditor concentration in local audit markets with PwC overlapping offices, the merger improved (rather than hurt) audit quality in those markets. Overall, our study contributes to the extant sparse literature on the effect of Big N mergers on audit quality, and is of potential interest to regulators.

We investigate whether the financial riskiness of large U.S. audit firm clienteles varied with the changing audit litigation liability environment during the period 1975‐99. Partitioning the period of study into four distinct periods (a benchmark period (1975‐84), a period of increasing concerns about litigation liability (1985‐89), a period of lobbying for reform (1990‐94), and a post‐relief period (1995‐99)), we find some evidence of risk decreases during 1985‐89, strong evidence of risk decreases during 1990‐94, and strong evidence of risk increases during 1995‐99. However, we also find that over the period of our study, a time during which Big 6 market shares grew appreciably, the proportion of litigious‐industry clients in Big 6 client portfolios grew at about the same rate as the proportion of such clients in the population. Moreover, the Big 6 share of the financially riskiest clients in the economy did not grow as fast as the overall Big 6 market share. In sum, although our evidence is consistent with the hypothesis that the riskiness of Big 6 client portfolios responded to changes in the audit litigation liability environment, we find no systematic evidence of a "race to the bottom" or "bottom fishing" by these firms in a bid to increase their market shares.

Under the assumption that audit quality relates positively to unobservable financial reporting quality, we investigate whether audit quality is associated with the predictability of accounting earnings by focusing on analyst earnings forecast properties. The evidence shows that analysts' earnings forecast accuracy is higher and the forecast dispersion is smaller for firms audited by a Big 5 auditor. We further find that auditor industry specialization is associated with higher forecast accuracy and less forecast dispersion in the non-Big 5 auditor sample but not in the Big 5 auditor sample. Overall, our results suggest that high-quality audit provided by Big 5 auditors and industry specialist non-Big 5 auditors is associated with better forecasting performance by analysts.

This study investigates whether and how a firm's real earnings management (REM) is influenced by the strength of a country's legal regime and the presence of a Big 4 auditor. In a cross‐country examination using data from 22 countries, we find that REM increases in countries with stronger legal regimes as firms switch from accrual‐based earnings management (AEM) to REM. The presence of a Big 4 auditor reduces REM (as well as AEM) and attenuates the positive relation between legal regime strength and REM. Our results suggest that higher‐quality auditors limit client firms’ use of REM, especially in countries with a strong legal regime.

In this paper, we first develop a model in which national legal environments play a crucial role in determining auditor effort and audit fees. Our model predicts that: (1) audit fees increase monotonically with the strength or strictness of a country’s legal liability regime; (2) given a legal liability regime, Big 4 auditors charge higher audit fees than non-Big 4 auditors; and (3) the Big 4 fee premium decreases as a country’s legal regime shifts from a weak to a strong regime. We then test the model’s predictions using a large sample of audit clients from 15 countries with different legal regimes where audit fee data are publicly available. The results of our cross-country regressions strongly support the above three predictions, and are robust to a variety of sensitivity checks. Furthermore, we find that the effects of a legal regime on audit pricing and the Big 4 premium are more salient for the small client segment than for the large client segment. Overall, our regression results indicate that a country’s legal environment plays an important role in determining both audit fees and the fee spread between Big 4 and non-Big 4 auditors.

Using 18,253 firm-year observations from 1998 through 2003, we build on literature suggesting that more informative disclosures allow returns to better reflect future earnings and test whether management earnings per share forecasts and their characteristics influence the future earnings response coefficient (FERC). We find that FERCs are greater for forecasting firms and when forecasts are more frequent or precise. We suggest that more frequent and more precise forecasts assist investors in better predicting future earnings. Importantly, we find that quarterly and short-term forecasts incrementally increase the association between returns and future earnings beyond annual and long-term forecasts; thus, even short-term, quarterly forecasts allow investors to form better expectations about future earnings. This suggests a benefit of quarterly earnings forecasts possibly overlooked in recommendations from the United States Chamber of Commerce, CFA Institute, Business Roundtable Institute for Corporate Ethics, and The Conference Board to eliminate quarterly earnings guidance.

We find that financial statement comparability enhances the ability of current period returns to reflect future earnings, as measured by the future earnings response coefficient (FERC). This suggests that comparability improves the informativeness of stock prices and allows investors to better anticipate future firm performance. In addition, using both the FERC and stock price synchronicity tests, we find that comparability increases the amount of firm‐specific information (rather than market/industry‐level information) reflected in stock prices. Analysts play an important role in improving stock price informativeness by producing more firm‐specific information when comparability is high. These findings suggest that comparability lowers the costs of gathering and processing firm‐specific information.

We study the effects of cross-listings on audit fees. We first develop a model in which legal environments play a crucial role in determining the auditor's legal liability. Our model and analysis predict that auditors charge higher fees for firms that are cross-listed in countries with stronger legal regimes than they do for non-cross-listed firms and that the cross-listing audit fee premium increases with the difference in the strength of legal regimes between the cross-listed foreign country and the home country. We then empirically test these predictions. The results of our cross-country regressions strongly support our predictions. In addition, we find no significant cross-listing fee premium for firms that are cross-listed in countries whose legal regimes are. no stronger than those of their home countries. This suggests that cross-listing audit fee premiums are associated with increased legal liability and not with increased audit complexity per se. Our findings help explain why cross-listing premiums occur and what determines their magnitude.
