By considering investor order placement strategy, this paper demonstrates that transaction costs cause bid-ask spreads to be an equilibrium property of asset markets. With transaction costs, the probability of a limit order executing does not go to unity as the order is placed infinitesimally close to a counterpart market quote; thus, with certainty of execution at the counterpart market quote, a "gravitational pull" is generated that keeps counterpart quotes from being placed infinitesimally close to each other. An equilibrium spread is defined and its size linked to market thinness; implications are noted for the design of a trading system.

We examine whether the complexity of mandatory accounting disclosures prompts managers to voluntarily disclose adjusted measures of actual earnings performance, and whether this practice reflects attempts to obfuscate or mitigate the informational opacity accounting complexity creates for investors. Using the metadata in XBRL filings, we construct measures of accounting complexity that map directly to the mandated standards applied in financial statement filings. We find a positive and economically significant association between accounting complexity and managers’ propensity to disclose non-GAAP earnings information. This relation is robust and incremental to common measures of business and linguistic complexity, and the transitory nature of firms’ economic activities. We also find that the quality and informativeness of adjusted earnings information increases with accounting complexity, consistent with motives to better inform investors when accounting disclosures are complex. Overall, our results suggest that managers use non-GAAP earnings disclosure to mitigate the adverse informational effects of accounting complexity.

Using the complete history of regular quarterly and annual filings by U.S. corporations, we show that changes to the language and construction of financial reports have strong implications for firms’ future returns and operations. A portfolio that shorts “changers” and buys “nonchangers” earns up to 188 basis points per month in alpha (over 22% per year) in the future. Moreover, changes to 10‐Ks predict future earnings, profitability, future news announcements, and even future firm‐level bankruptcies. Unlike typical underreaction patterns, we find no announcement effect, suggesting that investors are inattentive to these simple changes across the universe of public firms.

Prior evidence shows a reduction in leverage after covenant violations, but we do not know whether covenants affect leverage before they are violated. In this study, we use an exogenous accounting-based shock to debt covenants that relaxed covenant tightness (SFAS 160) and examine whether covenants constrain leverage for borrowers that are close to violation, even when the borrower is financially healthy. We find that SFAS 160 increased debt levels in firms that were close to violation. This increase in debt was driven by financially healthy firms, suggesting the likelihood of future covenant violations could impede borrowing by firms. We also find an increase in investment sensitivity to Q after SFAS 160 in firms close to violation, suggesting the additional debt was used to make legitimate investments. Because SFAS 160 was passed in the midst of the financial crisis, it is difficult to generalize our findings to more normal financial periods.
