Piecewise Pseudo-maximum Likelihood Estimation in Empirical Models of Auctions.

In applications of game theory to auctions, researchers assume that players choose strategies based upon a commo nly known distribution of the latent characteristics. Rational behavior, within an assumed class of distributions for the latent process, imposes testable restrictions upon the data generating process of th e equilibrium strategies. Unfortunately, the support of the distributi on of equilibrium strategies often depends upon all of the parameters o f the distribution of the latent characteristics, making the standard application of maximum likelihood estimation procedures inappropriat e. The authors present a piecewise pseudo-maximum likelihood estimator as well as the conditions for its consistency and its asymptotic distribution.
