When the number of instruments increases at the same rate as the sample size, we establish that the conventional<jats:italic>AR<\/jats:italic>and<jats:italic>J<\/jats:italic>tests are asymptotically incorrect. Some versions of these tests, which are developed for situations with moderately many instruments, are also shown to be asymptotically invalid in this framework. We propose modifications of the<jats:italic>AR<\/jats:italic>and<jats:italic>J<\/jats:italic>tests that deliver asymptotically correct sizes. Importantly, the corrected tests are robust to the numerosity of the moment conditions in the sense that they are valid for both few and many instruments. The simulation results illustrate the excellent properties of the proposed tests.<\/jats:p>","DOI":"10.1017\/s0266466610000307","type":"journal-article","created":{"date-parts":[[2010,9,13]],"date-time":"2010-09-13T08:14:42Z","timestamp":1284365682000},"page":"427-441","source":"Crossref","is-referenced-by-count":38,"title":["SPECIFICATION TESTING IN MODELS WITH MANY INSTRUMENTS"],"prefix":"10.1017","volume":"27","author":[{"given":"Stanislav","family":"Anatolyev","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Nikolay","family":"Gospodinov","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"56","published-online":{"date-parts":[[2010,9,13]]},"reference":[{"key":"S0266466610000307_ref16","doi-asserted-by":"publisher","DOI":"10.1006\/jmva.1995.1083"},{"key":"S0266466610000307_ref15","doi-asserted-by":"publisher","DOI":"10.1214\/aoms\/1177731492"},{"key":"S0266466610000307_ref13","doi-asserted-by":"publisher","DOI":"10.1016\/S0047-259X(03)00096-4"},{"key":"S0266466610000307_ref11","doi-asserted-by":"publisher","DOI":"10.1016\/S0304-4076(01)00064-1"},{"key":"S0266466610000307_ref9","doi-asserted-by":"publisher","DOI":"10.1016\/j.jeconom.2006.06.008"},{"key":"S0266466610000307_ref8","doi-asserted-by":"publisher","DOI":"10.1016\/S0304-4076(03)00118-0"},{"key":"S0266466610000307_ref7","doi-asserted-by":"publisher","DOI":"10.1111\/j.1468-0262.2005.00632.x"},{"key":"S0266466610000307_ref6","doi-asserted-by":"crossref","first-page":"294","DOI":"10.1080\/07350015.1996.10524658","article-title":"Small-sample properties of GMM-based Wald tests","volume":"14","author":"Burnside","year":"1996","journal-title":"Journal of Business and Economic Statistics"},{"key":"S0266466610000307_ref4","doi-asserted-by":"publisher","DOI":"10.2307\/2297968"},{"key":"S0266466610000307_ref3","doi-asserted-by":"publisher","DOI":"10.2307\/2937954"},{"key":"S0266466610000307_ref1","doi-asserted-by":"crossref","first-page":"328","DOI":"10.1080\/07350015.1996.10524660","article-title":"GMM estimation of a stochastic volatility model: A Monte Carlo study","volume":"14","author":"Andersen","year":"1996","journal-title":"Journal of Business and Economic Statistics"},{"key":"S0266466610000307_ref12","doi-asserted-by":"publisher","DOI":"10.1016\/S0304-4076(99)00014-7"},{"key":"S0266466610000307_ref5","doi-asserted-by":"publisher","DOI":"10.2307\/2951662"},{"key":"S0266466610000307_ref14","unstructured":"Newey W.K.
