We propose a simple framework for understanding accounting-based stock return regularities. A firm's accounting reports provide noisy information about hidden economic states that evolve according to a Markov process. In response to the accounting reports, a representative Bayesian investor...

We propose and validate a new measure of earnings quality based on a hidden Markov model. This measure, termed earnings fidelity, captures how faithful earnings signals are in revealing the true economic state of the firm. We estimate the measure using a Markov chain Monte Carlo procedure in a...

We use a rational expectations model to examine how public disclosure requirements affect listing decisions by rent-seeking corporate insiders, and allocation decisions by liquidity traders seeking to minimize trading costs. We find that exchanges competing for trading volume engage in a...

Given a standard moral hazard problem, the agent's optimal compensation can be cast as a function of either (i) the gross outcome, or (ii) the net outcome, which is the gross outcome net of the agent's compensation. Contracts based on the net outcome are important in practice because (i)...

Evidence contrasting U.S. insider trades in high- and low-jeopardy periods and across firms at high and low risk for 10b-5 litigation indicates that insiders condition their trades on foreknowledge of price-relevant public disclosures, but avoid profitable trades when the jeopardy associated...

Regulation requiring insiders to publicly disclose their stock trades after the fact complicates the trading decisions of informed, rent-seeking insiders. Given this requirement, we present an insider's equilibrium trading strategy in a multiperiod rational expectations framework. Relative to...

We examine the stock option exercise decisions of over 50,000 employees at seven corporations to provide evidence on the distribution of price-relevant non-public information among employees. When option exercise (adjusted for other factors affecting exercise) is low, stock returns in the coming...

We investigate stock option exercise decisions by over 50,000 employees at seven corporations. Controlling for economic factors, psychological factors in*uence exer- cise. Consistent with psychological models of beliefs, employees exercise in response to stock price trends|exercise is positively...

Research in sociology and ethics suggests that individuals adhere to social norms of behavior established by their peers. Within an agency framework, we model endogenous social norms by assuming each agent's cost of implementing an action depends on the social norm for that action, defined to be...
