SIMILAR-ON-THE-BOUNDARY TESTS FOR MOMENT INEQUALITIES EXIST, BUT HAVE POOR POWER By
نویسندگان
چکیده
This paper shows that moment inequality tests that are asymptotically similar on the boundary of the null hypothesis exist, but have poor power. Hence, existing tests in the literature, which are asymptotically non-similar on the boundary, are not de cient. The results are obtained by rst establishing results for the nite-sample multivariate normal one-sided testing problem. Then, these results are shown to have implications for more general moment inequality tests that are used in the literature on partial identi cation. Keywords: Moment inequality, one-sided test, power, similar, test. JEL Classi cation Numbers: C12, C15.

Consistent and Asymptotically Similar MinP Tests of Multiple Inequality Moment Restrictions∗
This paper considers the general problem of testing multiple inequality moment restrictions against an unrestricted alternative. We first introduce a test based on a maximum statistic and show how, via a partially recentered bootstrap scheme, we may obtain a testing procedure that delivers, at least asymptotically, an exact α-level test for any configuration of the parameters on the boundary of...
متن کاملInference for Parameters Defined by Moment Inequalities Using Generalized Moment Selection By
The topic of this paper is inference in models in which parameters are defined by moment inequalities and/or equalities. The parameters may or may not be identified. This paper introduces a new class of confidence sets and tests based on generalized moment selection (GMS). GMS procedures are shown to have correct asymptotic size in a uniform sense and are shown not to be asymptotically conserva...

متن کاملNonparametric Inference Based on Conditional Moment Inequalities
This paper develops methods of inference for nonparametric and semiparametric parameters de ned by conditional moment inequalities and/or equalities. The parameters need not be identi ed. Con dence sets and tests are introduced. The correct uniform asymptotic size of these procedures is established. The false coverage probabilities and power of the CSs and tests are established for xed altern...
