Identification of auction models using order statistics
نویسندگان
چکیده
Auction data often contain information on only the most competitive bids as opposed to all bids. The usual measurement error approaches unobserved heterogeneity are inapplicable due dependence among order statistics. We bridge this gap by providing a set of positive identification results. First, we show that symmetric auctions with discrete identifiable using two consecutive statistics and an instrument. Second, extend results ascending unknown competition heterogeneity.

چکیده: فرض کنید که تابعی از اپسیلون یک مجموع نامتناهی از احتمالات موزون مربوط به مجموع های جزئی براساس یک دنباله از متغیرهای تصادفی مستقل و همتوزیع باشد، و همچنین فرض کنید توابعی مانند g و h وجود دارند که هرگاه امید ریاضی توان دوم x متناهی و امیدریاضی x صفر باشد، در این صورت می توان حد حاصلضرب این توابع را بصورت تابعی از امید ریاضی توان دوم x نوشت. حالت عکس نیز برقرار است. همچنین ما با استفاده...

In this paper, we study stochastic comparisons of order statistics of independent random variables with proportional hazard rates, using the notion of variance majorization.
متن کاملMicrophone Identification using Higher-Order Statistics
This paper presents a statistical framework for microphone identification using only digital audio recordings. To accomplish this task, the microphone-induced artifacts are modeled using a nonlinear function and then a statistical tool based on higher-order statistics is used to capture these artifacts. More specifically, polyspectral analysis is used to capture microphone-induced artifacts. Di...
متن کاملNonlinear system identification using higher order statistics
A general formula is given for the conditional mean in terms of higher order statistics. Using this formula, a general scheme for nonlinear system identi cation is introduced including a broad range of nonlinearities which depends on the probability density function of the input. As a special case of that general scheme, the polynomial system identi cation problem is treated. It is shown that o...
متن کاملIdentification of Search Models using Record Statistics∗
This paper shows how record-value theory, a branch of statistics that deals with the timing and magnitude of extreme values in sequences of random variables, can be used to nonparametrically identify the offer distribution of wages workers face. Using NLSY wage data, I show that the data supports the hypothesis that the wage offer distribution is Pareto but rejects that it is lognormal. In addi...
