This study examines how PCAOB international inspections of non-U.S. auditors affect international Merger and Acquisition (M&A) outcomes. We find that clients of inspected auditors are more likely to become acquisition targets after the public disclosure of auditor's inspection report. We also find that deal completion is more likely and deal announcement returns are higher if deals involve targets with auditors for which inspection reports are available. Engagement deficiencies and unremediated quality control deficiencies identified in inspection reports weaken the positive effect of PCAOB oversight on M&A outcomes. Collectively, our results suggest that PCAOB oversight reduces information uncertainty in M&A deals.

Using jumps in stock prices as a proxy for large information shocks, we provide evidence consistent with short-term underreaction in the US equity market. Strategies long (short) stocks with positive (negative) lagged jump returns earn significantly positive returns over the next one- to three-month horizons. The results based on intraday jumps, especially overnight jumps, provide further evidence consistent with underreaction. The underreaction is robust to controlling for other firm characteristics, extends stock return momentum over intermediate to short horizons, and captures market underreaction to information shocks beyond earnings surprises. We further show that limited investor attention contributes to short-term underreaction.

We examine whether the Public Company Accounting Oversight Board (PCAOB) international inspection program improves audit quality for a sample of non-US-listed foreign public client companies from 55 countries audited by foreign (i.e., non-US) auditors. For a sample of non-US-listed clients of PCAOB-registered foreign auditors, we find that initial PCAOB inspections improve audit quality, over and above the threat of such inspections, for foreign auditors’ non-US-listed foreign clients. Our findings document the benefits of PCAOB international inspections for foreign investors in non-US-listed foreign companies which could increase the acceptability of the PCAOB international inspection program abroad.

By employing two alternative measures of fundamental value, we reexamine the value relevance of accounting information over time. Consistent with some recent studies, we do not find evidence on the temporal decline in R 2s of conventional value-relevance regressions when the stock price is replaced by these measures as the dependent variable. Further, our results show that the divergence between fundamental value and the prevailing stock price (a) increases over time and (b) is associated with measures of noise trading and other arbitrage risks and costs. Additional analyses also reveal that proxies measuring the extent of noise trading increase over time. Overall, we do not find evidence that there is a loss over time in the value relevance of accounting information with respect to fundamental value. More importantly, we show that measures of price divergence are associated with noise trading as well as other arbitrage costs and risks (such as transaction costs and information uncertainty) that prohibit market prices from converging to fundamental values.

We show evidence that consistent with category-learning behavior, investors allocate more attention to macroeconomic news than to firm-specific news, such as earnings announcements. Despite the distracting effect of macroeconomic news on investor attention, we find that earnings announcements with concurrent macroeconomic news announcements actually have significantly stronger immediate market response and weaker post-earnings announcement drift. We hypothesize that the combined total attention to macroeconomic news and earnings announcements helps investors understand both the systematic and firm-specific components of earnings surprises. Consistent with the hypothesis, our results show that the macroeconomic news effect is mainly driven by firms with high exposure to macroeconomic news. Moreover, we show that the effect is stronger when macroeconomic news contains more information and for firms with greater information uncertainty. Finally, we provide evidence that macroeconomic news helps reduce stock return uncertainty and enhance stock price efficiency.
