We show that immediate and delayed abnormal returns following earnings announcement surprises differ across market states. Immediate abnormal returns are more sensitive to earnings surprises in down markets, while delayed abnormal returns are less sensitive; underreaction is attenuated in down...

One possible determinant of overpricing on asset markets is a lack of self-control abilities of traders. Self-control is the individual capacity to override or inhibit undesired behavioral tendencies such as impulses and to refrain from acting on them. We implement the first experiment that is...

This paper studies the effect of new fund flows on investment behavior and the resulting equilibrium price of risk. The Small Fund Industry model shows equilibria with overinvestment in unprofitable and underinvestment in profitable investment opportunities. The Large Fund Industry model derives...

We examine the role of concurrent information in the striking increase in investor response to earnings announcements from 2001 to 2016, as measured by return variability and volume following Beaver (1968). We find management guidance, analyst forecasts, and disaggregated financial statement...
