         內容簡介:This paper provides a test for existence and identification of a solution for nonparametric instrumental variable models. A solution to the nonparametric instrumental variable model can be linked to the left invertibility of the corresponding integral operator. Based on the connection, we give necessary and sufficient conditions for existence of a unique solution and provide a uniformly invertible test statistic for existence and identification. The uniformly invertible test generalizes the rank test of the discrete case in Newey and Powell (2003). The test is consistent and can be used to test consistency of the proposed finite truncation nonparametric estimator. We investigate the finite sample properties of the test and estimator through a Monte Carlo study.                     報告人簡介:徐吉良,暨南大學經濟與社會研究院副教授
