內容簡介:In this paper, we develop an integrated quantile based nonparametric test for exogenous participation hypothesis in first price auctions. Using the fact that two distributions being equal is equivalent to their integrals over arbitrary interval being equal, we propose simple quantile based statistic for testing the null hypothesis that the private values of bidders are drawn from the same distribution in two samples of auctions with different numbers of bidders against the alternative hypothesis that the private value distributions are different with different numbers of bidders. Our test is convenient in practice since it only involves one step estimation of quantile functions of bids. We also characterize the asymptotic distribution of the integrated quantile based statistic under the null hypothesis with regularity conditions. We show that it is the supremum of absolute value of Gaussian process with mean zero. The simulation results show that our test performs well under moderate sample sizes. Finally, we adapt our testing procedure to auctions with entry.
