Using data generated from laboratory experiments, we test and compare the empirical accuracy of two models that focus on judgment errors associated with processing information from random sequences. We test for regime-shifting beliefs of the type theorized in Barberis, Shleifer, and Vishny...

Recent empirical studies find that options trading enhances firm value by allowing for a more efficient allocation of firm resources. In this paper, we develop and test the hypothesis that, in addition to a more efficient allocation of firm resources, options trading also enhances firm value...
