Abstract:To understand the effects of incentives on crowdsourcing participation and submission quality, we conduct a field experiment on Taskcn, a large Chinese crowdsourcing site using all-pay auction mechanisms.We systematically vary the size of the reward, and the presence of a soft reserve in the form of the early entry of a high-quality submission. We find that a higher reward induces significantly more submissions and attracts higher quality users. However, unpredicted by theory, we find that high-quality users are significantly less likely to enter tasks where a high quality solution has already been submitted, resulting in lower quality in subsequent submissions in such soft reserve treatments.
