We study whether bestowing chief executive officer (CEO) and board chairman duties on one individual affects a boards decision to dismiss an ineffective CEO. The results show that the sensitivity of CEO turnover to firm performance is significantly lower when the CEO and chairman duties are vested in the same individual. These results are consistent with the view that the lack of independent leadership in firms that combine the CEO and Chairman positions makes it difficult for the board to remove poorly performing managers.

We investigate a pervasive voluntary disclosure practice—managers including balance sheets with quarterly earnings announcements. Consistent with expectations, we find that managers voluntarily disclose balance sheets when current earnings are relatively less informative, or when future earnings are relatively more uncertain. Specifically, balance sheet disclosures are more likely among firms: (1) in high technology industries; (2) reporting losses; (3) with larger forecast errors; (4) engaging in mergers or acquisitions; (5) that are younger; and (6) with more volatile stock returns. This is consistent with managers disclosing balance sheets in response to investor demand for value relevant information to supplement earnings.

This paper examines the impact of measuring accruals as the change in successive balance sheet accounts, as opposed to measuring accruals directly from the statement of cash flows. Our primary finding is that studies using a balance sheet approach to test for earnings management are potentially contaminated by measurement error in accruals estimates. In particular, if the partitioning variable used to indicate the presence of earnings management is correlated with the occurrence of mergers and acquisitions or discontinued operations, tests are biased and researchers are likely to erroneously conclude that earnings management exists when there is none. Additional results show that the errors in balance sheet accruals estimation can confound returns regressions where discretionary and non‐discretionary accruals are used as explanatory variables. Moreover, we demonstrate that tests of market mispricing of accruals will be understated due to erroneous classification of “extreme” accruals firms.

This paper uses recursive methods to characterize the payoff frontier of self-enforcing trade agreements between countries of asymmetric size. We show that at points on the frontier where only one country's incentive constraint binds, the efficient agreement will be a non-stationary one that starts with a positive trade distortion but eventually reaches free trade. Our analysis illustrates how (i) relative country size, (ii) consumption smoothing incentives, and (iii) sunk investments affect the form of efficient trade agreements. In contrast to previous work on gradualism, our results are obtained from a model in which the economic environment is stationary.

Abstract This paper examines the effect of earnings announcements on information asymmetry as perceived by specialists. We use changes in quoted bid‐ask spreads and depths (relative to the average value in the non‐announcement period) as proxies for changes in information asymmetry in the market. To our knowledge, we are the first to employ a model that captures the simultaneous nature of the specialists' choice of spreads and depths in reaction to earnings news. We provide evidence that spreads are wider and depths are smaller before the release of earnings announcements. We also find that changes to depths are greater for announcements of quarterly earnings than for announcements of annual earnings and changes to spreads persist longer into the post‐announcement period when announcements are made outside trading hours. These changes to spreads and depths persist when earnings announcements are made after trading hours.

Substantial academic research explains why firms should hedge, but little work has addressed how firms should hedge. We assume that firms can experience costly states of nature and derive optimal hedging strategies using vanilla derivatives (e.g., forwards and options) and custom “exotic” derivative contracts for a value-maximizing firm facing both hedgable (price) and unhedgable (quantity) risks. Customized exotic derivatives are typically better than vanilla contracts when correlations between prices and quantities are large in magnitude and when quantity risks are substantially greater than price risks. Finally, we discuss how our model may be applied in practice.
