Professor Dechow's research focuses on accounting accruals, the quality and reliability of earnings, the use of earnings information in predicting stock returns, and the effect of analysts' forecasts on investors’ perceptions of firm value.Accounting and Auditing Enforcement Release Dataset: https://sites.google.com/usc.edu/aaerdataset/home

Implied equity duration was originally developed to analyze the sensitivity of equity prices to discount rate changes. We demonstrate that implied equity duration is also useful for analyzing the sensitivity of equity prices to pandemic shutdowns. Pandemic shutdowns primarily impact short-term cash flows, thus they have a greater impact on low-duration equities. We show thatimplied equity duration has a strong positive relation to U.S. equity returns and analyst forecast revisions during the onset of the 2020 COVID-19 shutdown. Our analysis also demonstrates that the underperformance of “value” stocks during this period is a rational response to their lower durations.
We hypothesize that one way accounting practices spread is through law firm connections. We investigate this prediction by examining companies that avoided reporting compensation expense by engaging in stock option backdating. We hypothesize that executives engaged in backdating because they were desensitized to its inappropriateness when they learned through their legal counsel that other companies were engaging in thispractice. We identify backdating companies through backdating-related restatements of earnings. Using network analysis, we find that backdating companies are highly connected with other backdating companies via shared law firms. Logistic regressions reveal that the odds of a company backdating are 53 to 88 percent higher when its law firm has another client that backdates, and that law firm connections are incremental to board interlocks and geographic location. Finally, law firms with backdating clients have more other clients with ‘‘lucky’’ grants, suggesting that backdating spread to other companies, but only some restated.
This paper investigates whether maintaining a reputation for consistently beating analysts’ earnings expectations can motivate executives to move from “within GAAP” earnings management to “outside of GAAP” earnings manipulation. We analyze firms subject to SEC enforcement actions and find that these firms consistently beat analysts’ quarterly earnings forecasts in the three years priorto the manipulation period and continue to do so by smaller “beats” during the manipulation period. We find that manipulating firms beat expectations around 86 percent of the time in the12 quarters prior to the manipulation period (versus 75 percent for control firms) and that manipulation often ends with a miss in expectations. We document that executives of manipulating firmsface strong stock market and CEO pressure to perform. Prior to the manipulation period, these firms have high analyst optimism, growing institutional interest, and high market valuations, alongwith powerful CEOs. Further, we find that maintaining a reputation for beating expectations is more important than CEO overconfidence and is incremental to CEO equity incentives forexplaining manipulation. Our results suggest that pressure to maintain a reputation for beating analysts’ expectations can encourage aggressive accounting and, ultimately, earnings manipulation.
