Abstract This paper examines whether differences in accrual accounting methods across balance sheet accounts influence the time‐series process of earnings. We define earnings quality as the responsiveness of earnings to shifts in permanent earnings and predict that responsiveness will increase in a firm's use of variable rate debt, where accruals move directly with shifts in interest rates. We also predict that responsiveness will decrease in a firm's investment in property plant and equipment because depreciation is largely predetermined and does not respond to shifts in opportunity costs. </P><P>To test these hypotheses, we regress earnings on lagged earnings and a proxy for permanent earnings (that is, the implied dividend annuity in lagged equity value). Within the context of an adjustment cost model, this regression captures the responsiveness of earnings by the coefficient on lagged price and by one minus the coefficient on lagged earnings. Consistent with this framework, we find the unconstrained estimated coefficients on these two variables to be negatively correlated. Furthermore, consistent with our hypotheses, we find that the coefficient on lagged earnings (lagged price) is positively (negatively) associated with the relative magnitude and life of fixed assets on the balance sheet and negatively (positively) associated with the relative magnitude of variable rate debt on the balance sheet.</P>
