Earnings Management? Erroneous Inferences Based on Earnings Frequency Distributions
提供三方面证据，说明盈余分布中所谓的“间断”现象很可能由盈余管理之外的因素导致，提醒研究者不能仅凭分布形状就断定存在盈余管理。
ABSTRACT A vast literature following Hayn [1995] and Burgstahler and Dichev [1997] attributed the so‐called “discontinuities” in earnings distributions around zero to earnings management. Despite recent evidence that these discontinuities are likely caused by other factors, researchers and teachers continue to point to the shapes of these distributions as evidence of earnings management. We provide three sets of further evidence that these discontinuities are likely caused by factors other than earnings management: (1) we provide, as an example, a detailed analysis of the severe effects of sample selection in a recent study; this study erroneously concludes that the shape of an earnings distribution is evidence of earnings management, (2) we provide a simple explanation for the shape of the earnings distribution that is most often cited as evidence of earnings management; the relation between earnings and prices differs with the magnitude and the sign of earnings, and (3) we provide further examples that support the main point of our paper; evidence beyond the mere shape of a distribution must be brought to bear before researchers can draw conclusions regarding the presence/absence of earnings management.
