Topic: Expert Rating versus Crowd Voting: Impact of Selection Mechanisms on Crowdsourcing Contests

Speaker: De Liu, Carlson School of Management, University of Minnesota

Time: Monday, July 3rd, 10:30-12:00 a.m

Place: Room 217, Guanghua Building 2

Abstract:

While expert rating is the default selection mechanism for many crowdsourcing contests, crowd voting is emerging as a new alternative. Using a novel database of crowdsourcing contests that allow independent expert rating and crowd voting in the same contest, we evaluate the impact of selection mechanisms on participation and winner determination. We find that including crowd voted prizes increases the odds of overall participation by 15%. It attracts those who are better equipped to win crowd-voted prizes and discourages those who are better equipped to win expert-rated prizes. An analysis of winner determination confirms that contestants who have performed well in crowd prizes are more likely to rank higher in crowd voting but not in expert rating. Furthermore, contestants who engage peers by praising their entries tend to rank higher in crowd voting, but not in expert rating. Overall, our findings suggest that crowd voting has an added benefit of encouraging broader participation and impacts the way winners are selected.
