The five-day workweek system and investor inattention

Research output: Journal Publications and ReviewsRGC 21 - Publication in refereed journalpeer-review

Abstract

In this paper, we show that work schedule is a key factor driving investor inattention to Friday earnings announcements using the introduction of the five-day workweek system in the financial sector of Korea in 2002 as a natural experiment. Our analyses show a stronger immediate response and a weaker delayed response to Friday news under the six-day workweek system. The trend was, however, reversed under the five-day workweek system. We also find out consistent evidence from the movement of trading volume. These findings demonstrate that the trade-off between weekend distraction and additional working hours during the weekend determines investors’ attention to Friday earnings announcements.
