We examine the relative importance of firm, industry and country characteristics in explaining earnings quality in a wide sample of firms in 38 countries over 1990–2003. An aggregate earnings quality measure based on seven earnings attributes (accruals quality, persistence, predictability, smoothness, value relevance, timeliness and conservatism) indicates firm and industry characteristics today explain much more of the variation in earnings quality rankings than country characteristics. The main results hold for different levels of a country's economic development and investor protection. We also find that firm and industry characteristics became more important in the late 1990s as accounting and financial globalization accelerated. Thus, firm and industry characteristics have incremental explanatory power beyond cross-country variation in determining earnings quality worldwide.
