ARE PROMISES MEANINGLESS IN AN UNCERTAIN CROWDFUNDING ENVIRONMENT?
利用Kickstarter数据，分析影响众筹项目按时交付奖励的因素，发现延迟普遍存在且难以用项目特征解释，揭示了众筹中奖励的不确定性。
We use a prominent crowdfunding organization, Kickstarter, to analyze the factors that determine timeliness of delivery of rewards to financial backers. We seek to determine the extent to which promised rewards are delivered on time and to characterize projects that have stronger likelihood of timely delivery of rewards. We find that lateness commonly occurs, yet cannot be explained universally with any given set of project characteristics, implying that the uncertainty of rewards involved with crowdfunding entities is difficult to overcome.
