我们的比赛模型与一个固定比例的奖品,如分级曲线,作为所有支付拍卖,更高的努力弱增加的可能性奖。我们发现理论预测的异质性影响拍卖规模的努力,从高和低类型。我们在实验室实验中测试我们的预测,比较行为在两个投标人,一个奖项的拍卖行为在20个投标人,10个奖项的拍卖。我们发现一个统计上显着增加11.8%,总投标时,从小到大的拍卖。影响是异质的:随着拍卖规模的增加,低类型减少努力,但高类型增加努力。此外,更大的拍卖提供了努力和能力之间更强的等级相关性,将更多的奖品授予更高技能的人,并提高了奖品分配的效率。
We model contests with a fixed proportion of prizes, such as a grading curve, as all-pay auctions where higher effort weakly increases the likelihood of a prize. We find theoretical predictions for the heterogeneous effect auction size has on effort from high- and low-types. We test our predictions in a laboratory experiment that compares behavior in two-bidder, one-prize auctions with behavior in 20-bidder, 10-prize auctions. We find a statistically significant 11.8% increase in aggregate bidding when moving from the small to large auction. The impact is heterogeneous: as the auction size increases, low-types decrease effort but high-types increase effort. Additionally, the larger auction provides a stronger rank-correlation between effort and ability, awarding more prizes to the higher-skilled and improving the efficiency of prize allocation.
