[email protected] August 2013 Abstract: We specify measures of accounting consistency based on the textual similarity of accounting policy footnotes both across time and within industry and we examine how these measures relate to earnings quality. Consistency over time is positively associated with earnings quality, as proxied by earnings persistence, predictability, smoothness, accrual quality, and absolute discretionary accruals. We also find a positive association between accounting consistency within industry and accrual quality and absolute discretionary accruals proxies, but this positive association stems from measurement error in the earnings quality proxies. Our results suggest that accounting consistency is an important factor in the measurement of earnings quality.

Introduction Earnings quality is a frequently studied, albeit elusive, construct in accounting research. The large surge of research on earnings quality has prompted some recent reflection about what earnings quality is and the importance of measurement in this research. Dechow et al. (2010) note that various proxies are used for earnings quality and that each of these proxies capture different aspects of quality.
