I present evidence consistent with managers using derivatives and discretionary accruals as partial substitutes for smoothing earnings. Using 1994–1996 data for a sample of Fortune 500 firms, I estimate a set of simultaneous equations that captures managers' incentives to maintain a desired level of earnings volatility through hedging and accrual management. These incentives include increasing managerial compensation and wealth, reducing corporate income taxes and debt financing costs, avoiding underinvestment and earnings surprises, and mitigating volatility caused by low diversification. After controlling for such incentives, I find a significant negative association between derivatives' notional amounts and proxies for the magnitude of discretionary accruals.

The balance sheet accumulates the effects of previous accounting choices, so the level of net assets partly reflects the extent of previous earnings management. We predict that managers' ability to optimistically bias earnings decreases with the extent to which the balance sheet overstates net assets relative to a neutral application of GAAP. To test this prediction, we examine the likelihood of reporting various earnings surprises for 3,649 firms during 1993–1999. Consistent with our prediction, we find that the likelihood of reporting larger positive or smaller negative earnings surprises decreases with our proxy for overstated net asset values.

We examine the value relevance of a comprehensive set of summary performance measures including sales, earnings, comprehensive income, and operating cash flows. We find that, while value relevance peaks for measures “above the line,” no single measure dominates around the world. Instead, a measure is more relevant when it captures, directly and quickly, information about firms’ cash flows. Specifically, for each performance measure by country, we estimate eight attributes commonly used to assess earnings quality. We find these attributes highly correlated—most of their variance is explained by only two principal factors. A factor capturing articulation with cash flows is positively associated with a measure’s value relevance; a factor reflecting the measure’s persistence, predictability, smoothness, and conservatism is negatively associated. Our results suggest that, when it comes to equity valuation, accounting researchers and standard-setters should focus not on what performance measure is “best” at a given point in time, but on the underlying attributes that investors find most relevant.

Using functional magnetic resonance imaging, we capture neural activity in the ventral striatum—a key area in the human brain's reward processing circuit—of 35 adult investors learning the earnings per share disclosed by 60 publicly traded companies. Before imaging, investors forecasted each company's earnings and took either a long or a short position in its stock. Consistent with prospect theory, we find strong neurobiological evidence of an asymmetric reaction to positive and negative earnings surprises. Moreover, investors' personality traits and investment positions, as well as firms' earnings predictability, modulate the brain's reaction to earnings news. We also find a strong association between the magnitude of the brain's reaction and risk-adjusted stock returns and abnormal share trading around earnings announcements for our sample firms; these findings evince the brain's reaction to earnings news as an alternative, biological measure of the information content of earnings.
