Charity Art Auctions
利用eBay艺术品拍卖数据，发现慈善属性使成交概率提高46%、竞拍人数增加111%、成交价提高45%，但效果随时间递减，存在捐赠疲劳现象。
Abstract Using a unique panel data set of art auctions on eBay, we conduct an empirical analysis of the impact of charity status on the outcome of an auction and find it to be substantial. Charity status increases the probability of sale by 46%, the observed number of bidders by 111% and the sale price by 45%. In addition, charity status substantially lowers the auction's opening price. Interestingly, the effect of charity status declines over time indicating that charity auctions may be susceptible to donor fatigue.
