Earnings Quality Measures and Excess Returns

This paper examines how commonly used earnings quality measures fulfill a key objective of financial reporting, i.e., improving decision usefulness for investors. We propose a stock-price-based measure for assessing the quality of earnings quality measures. We predict that firms with higher earnings quality will be less mispriced than other firms. Mispricing is measured by the difference of the mean absolute excess returns of portfolios formed on high and low values of a measure. We examine persistence, predictability, two measures of smoothness, abnormal accruals, accruals quality, earnings response coefficient and value relevance. For a large sample of US non-financial firms over the period 1988–2007, we show that all measures except for smoothness are negatively associated with absolute excess returns, suggesting that smoothness is generally a favorable attribute of earnings. Accruals measures generate the largest spread in absolute excess returns, followed by smoothness and market-based measures. These results lend support to the widespread use of accruals measures as overall measures of earnings quality in the literature.

Audit Fees and IAS/IFRS Adoption: Evidence from the Banking Industry

The adoption of International Accounting Standards/International Financial Reporting Standards (IAS/IFRS) has two opposite effects on audit fees: on the one hand, greater effort is required from auditors, which is likely to be reflected by higher fees; on the other hand, if IAS/IFRS improve the quality of financial reporting, expected liability costs could decrease and lower fees may be demanded. We consider a large sample of Italian banks and we examine the effect of IAS/IFRS adoption on audit fees. The results show that higher fees (19.29 per cent in real terms) are paid after the switch to the new standards. Using a standard earnings management model, we do not find support for the idea that financial reporting quality is affected by the adoption of IAS/IFRS. The observed increase in fees is positively associated with the presence of financial derivatives held for hedging purposes. This paper extends the findings of prior research on the effect of IAS/IFRS adoption on audit fees; contrary to prior contributions, our analysis concentrates on the banking industry. Furthermore, unlike prior works, we consider both listed and non-listed firms.

Accounting-Based Anomalies in the Bond Market

We examine the relation between future bond returns and 32 accounting-based fundamental variables shown by other researchers to be related to future stock returns. Findings indicate that the frequency of significant returns to trading strategies based on these anomalies is similar in both the bond and stock markets. The magnitude of returns is generally lower with bonds, but the significance and Sharpe ratios of these returns are comparable to those observed with stocks. Although the correlation between bond and stock returns is high, we document several intriguing differences between the returns to bond and stock trading strategies. Surprisingly, the significance of bond returns is generally robust to controlling for the equity returns of the hedge strategies.

Managerial Discretion in Accruals and Informational Efficiency

In this paper, we examine the relation between managerial discretion in accruals and informational efficiency. We measure managerial discretion in accruals by the absolute value of abnormal accruals. Assuming that efficient prices follow a random walk, we measure informational efficiency by using stock return variance ratios. We find that the absolute value of abnormal accruals is negatively associated with the price deviation from a random walk pattern, estimated in the 12-month period subsequent to the accrual reporting; hence, future informational efficiency increases with the extent to which managers exercise discretion over accruals. The results are consistent with the view that discretionary accruals, on average, convey useful information to investors and facilitate the price convergence to its fundamental value. Our findings are robust to a battery of tests, including tests to validate both our measures of informational efficiency and our measure of managerial discretion in accruals.

Managerial Discretion in Accruals and Informational Efficiency: MANAGERIAL DISCRETION AND INFORMATIONAL EFFICIENCY

In this paper, we examine the relation between managerial discretion in accruals and informational efficiency. We measure managerial discretion in accruals by the absolute value of abnormal accruals. Assuming that efficient prices follow a random walk, we measure informational efficiency by using stock return variance ratios. We find that the absolute value of abnormal accruals is negatively associated with the price deviation from a random walk pattern, estimated in the 12‐month period subsequent to the accrual reporting; hence, future informational efficiency increases with the extent to which managers exercise discretion over accruals. The results are consistent with the view that discretionary accruals, on average, convey useful information to investors and facilitate the price convergence to its fundamental value. Our findings are robust to a battery of tests, including tests to validate both our measures of informational efficiency and our measure of managerial discretion in accruals.
