There is an increasing number of Collaborative Question Answering (CQA) websites and
a growing reliance of the online community on user-generated content. In this paper,
we study users’ motivation to win social recognition contests (best answers) and how
multitasking and flexible hours influence the rate of winning contests. Heterogeneity of
contest motivation is estimated at the user level in a standard contest framework and
used to demonstrate that, for those who are more highly motivated to win contests,
multitasking across subjects is associated with a lower performance rate, while flexible
hours are associated with a higher performance rate.
