A Market-Based Evaluation of Discretionary Accrual Models

In this study we specify a simple earnings model, present managerial discretion hypotheses from existing literature, and assume efficient markets in order to evaluate five discretionary-accrual models. The five discretionary accrual models are the same as those evaluated in Dechow, Sloan, and Sweeney 1995. The models are Healy 1985; DeAngelo 1986; Jones 1991; Jones as modified in Dechow, Sloan, and Sweeney 1995; and the industry model proposed by Dechow and Sloan 1991. We specify three managerial discretion hypotheses. First, under the performance measure hypothesis, discretionary accruals help managers produce a reliable and more timely measure of firm performance (i.e., earnings) than using nondiscretionary accruals alone. Second, the opportunistic accrual management hypothesis is that discretionary accruals are employed to hide poor performance or postpone a portion of unusually good current earnings to future years. Finally, discretionary accruals are noise in earnings. This is the noise hypothesis. Our contribution is to make the joint hypotheses explicit and generate explicit predictions about the relative variability of earnings components,
