An exploratory study of earnings management detectability, analyst coverage and the impact of IFRS adoption: Evidence from China

摘要

Analysts serving as external monitors to managers is a topic of considerable interest in the analyst coverage literature. There are two outcomes of analyst coverage studies: curbing and stimulating earnings management. However, recent studies (such as Yu, 2008) only provide evidence supporting the curbing side. Given the fact that the data of these studies focus on developed markets and the finding of Rodriguez-Perez and Hemmen (2010) that external governance mechanisms may stimulate earnings management in an opaque information environment, we conjecture whether stimulating side would be dominant in emerging markets. China offers a valuable setting for us to test the question. Using the data of China capital market from 2003 to 2009, we find that analyst coverage stimulates earnings management through above-the-line items (ALIs) where earnings management cannot be easily detected, and curbs earnings management through below-the-line items (BLIs) where earnings management can be easily detected. We also find that the adoption of International Financial Reporting Standards (IFRS) in China does create many new opportunities for managers' earnings management but does not significantly improve the monitoring effect of analyst coverage. We only find that compared to those without analyst coverage, firms with analyst coverage have a lower level of earnings management through BLIs after IFRS adoption. These findings suggest that information opacity may weaken the monitoring effect of external corporate governance mechanisms and high quality accounting standards in the literal sense may not enhance the monitoring effect of external corporate governance mechanisms if it is not compatible with the market's institutional environment. In addition, we find that firms with earnings meeting the benchmark have a lower level of earnings management, which indicates that bright-line accounting based rules used in emerging capital markets may constrain the managers' behavior.
