خلق و خوی مثبت و تصمیمات سرمایه گذاری : شواهد از حضور فیلم کمدی در ایالات متحده

Positive mood has been repeatedly shown to affect decision-making under risk. In this study I exploit the time-series variation in the domestic theatrical release of comedy movies as a natural experiment for testing the impact that happy mood (proxied by weekend comedy movie attendance) has on the demand for risky assets (proxied by the performance of the U.S. stock market). Using a sample of data from 1994 to 2010, I estimate that an increase in comedy attendance on a given weekend is followed by a decrease in equity returns on the subsequent Monday, which is consistent with the mood-maintenance hypothesis.
