I investigate the collective impact of passive and active investment on stock price efficiency using a quasi-natural experiment.

Institutional factors are then taken into consideration as possible explanatory variables of the dis...

These digressions may be viewed as particularly pronounced forms of unsolicited interruptions as they contain information not directly related to the caller’s intended activity. In human–human conversation, interruptions are considered to be speech acts which intrinsi...
