Dovonon and Renault (2013) recently raised a local identification issue stemming from this type of degenerate Jacobian. The local identification issue leads to a slow rate of convergence of the GMM estimator and a nonstandard asymptotic distribution of the over-identification test statistics. We show that the known form of rank-deficient Jacobian matrix contains nontrivial information about the economic model. By exploiting such information in estimation, we provide GMM estimator and over-identification tests with standard properties. The main theory developed in this paper is applied to the estimation of and inference about the common conditionally heteroskedastic (CH) features in asset returns. The performances of the newly proposed GMM estimators and over-identification tests are investigated under the similar simulation designs used in Dovonon and Renault (2013).<\/jats:p>","DOI":"10.1017\/s026646661700024x","type":"journal-article","created":{"date-parts":[[2017,6,6]],"date-time":"2017-06-06T06:02:26Z","timestamp":1496728946000},"page":"790-814","update-policy":"http:\/\/dx.doi.org\/10.1017\/policypage","source":"Crossref","is-referenced-by-count":12,"title":["ON STANDARD INFERENCE FOR GMM WITH LOCAL IDENTIFICATION FAILURE OF KNOWN FORMS"],"prefix":"10.1017","volume":"34","author":[{"given":"Ji Hyung","family":"Lee","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zhipeng","family":"Liao","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"56","published-online":{"date-parts":[[2017,6,6]]},"reference":[{"key":"S026646661700024X_ref11","doi-asserted-by":"crossref","first-page":"369","DOI":"10.1080\/07350015.1993.10509966","article-title":"Testing for common features","volume":"11","author":"Engle","year":"1993","journal-title":"Journal of Business and Economic Statistics"},{"key":"S026646661700024X_ref24","doi-asserted-by":"publisher","DOI":"10.2307\/2171753"},{"key":"S026646661700024X_ref5","doi-asserted-by":"publisher","DOI":"10.1016\/0304-4076(92)90032-M"},{"key":"S026646661700024X_ref4","doi-asserted-by":"publisher","DOI":"10.1111\/j.1467-6419.2004.00232.x"},{"key":"S026646661700024X_ref22","unstructured":"Sentana E .
