Not that much in economic terms, or so it seems according to a new paper by David Yarmack:

This paper shows connections between chief executive officers’ (CEOs’) absences from headquarters and corporate news disclosures. I identify CEO absences by merging records of corporate jet flights and CEOs’ property ownership near leisure destinations. CEOs travel to their vacation homes just after companies report favorable news, and CEOs return to headquarters right before subsequent news releases. When CEOs are away, companies announce less news, mandatory disclosures occur later, and stock volatility falls sharply. Volatility increases when CEOs return to work. CEOs spend fewer days out of the office when ownership is high and when weather is bad at their vacation homes.

The published version is here, other versions are here. Hat tip goes to the excellent Kevin Lewis.
