Prior research finds evidence suggesting a long-term trend of declining accruals quality in the U.S. Using the Dechow and Dichev (2002) accruals quality measure, we provide new evidence that this decline began to reverse around 2000, with accruals quality generally improving through 2016. We...

We find that lower ex-ante earnings volatility leads to higher Post-Earnings Announcement Drift (PEAD). PEAD is a function of both the magnitude of an earnings surprise and its persistence. While prior research has largely investigated market reactions to the magnitude of the earnings surprise,...

We evaluate the impact of complexity and content of new information on stock return volatility dynamics around 10-K fillings. On average, return volatility increases by 0.4% in the first four weeks after the release of the report, followed by a 2.6% decrease in the subsequent six weeks. This...

This paper examines how a firm adjusts its disclosure quality in response to technological innovations that improve investors' private information. We show that more precise private information can endogenously amplify supply shocks and, hence, increase noise-driven (or non-fundamental) price...

This paper studies the impact that pre-IPO cash flow volatility has on the initial and long-term value of a publicly traded firm. From the perspective of corporate risk management theory, higher cash flow volatility should reduce value in the form of higher borrowing costs, reduced investment,...

This paper analyzes the asset pricing implications of periodic cash payouts within the context of a stationary rational expectations model with heterogeneous investors. The periodicity of cash payouts provides a natural motivation for time-varying conditional volatility in stock returns. I show...

The ad hoc Black-Scholes (AHBS) model is one of the most widely used option valuation models among practitioners models. The main contribution of this study is methodological. We have two main results: (1) we make the empirical observation that typically the call and put sneers are discontinuous...

We find that weekend, holiday and overnight trading breaks generate excessive perceived risk in the option markets, presumably due to asymmetric information, which, in turn, encourages uninformed option traders to postpone trading. This perceived risk subsides after two days accompanied by an...
