We propose a new identification strategy mainly based on the condition that the selection variable becomes independent of the covariates for large values of the outcome. No large support on the covariates is required. Moreover, we prove that this condition is testable. We finally show that our strategy can be applied to the identification of generalized Roy models.<\/jats:p>","DOI":"10.1017\/s026646661200028x","type":"journal-article","created":{"date-parts":[[2012,7,6]],"date-time":"2012-07-06T11:53:49Z","timestamp":1341575629000},"page":"213-224","source":"Crossref","is-referenced-by-count":22,"title":["ANOTHER LOOK AT THE IDENTIFICATION AT INFINITY OF SAMPLE SELECTION MODELS"],"prefix":"10.1017","volume":"29","author":[{"given":"Xavier","family":"D\u2019Haultfoeuille","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Arnaud","family":"Maurel","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"56","published-online":{"date-parts":[[2012,7,6]]},"reference":[{"key":"S026646661200028X_ref11","doi-asserted-by":"crossref","first-page":"679","DOI":"10.2307\/1913937","article-title":"Shadow prices, market wages, and labor supply","volume":"42","author":"Heckman","year":"1974","journal-title":"Econometrica"},{"key":"S026646661200028X_ref22","doi-asserted-by":"crossref","first-page":"S7","DOI":"10.1086\/260821","article-title":"Education and self-selection","volume":"87","author":"Willis","year":"1979","journal-title":"Journal of Political Economy"},{"key":"S026646661200028X_ref18","doi-asserted-by":"crossref","first-page":"777","DOI":"10.1016\/j.jeconom.2006.11.004","article-title":"Endogenous selection or treatment model estimation","volume":"141","author":"Lewbel","year":"2007","journal-title":"Journal of Econometrics"},{"key":"S026646661200028X_ref20","doi-asserted-by":"crossref","first-page":"40","DOI":"10.1017\/S0266466602181035","article-title":"On intercept estimation in the sample selection model","volume":"18","author":"Schafgans","year":"2002","journal-title":"Econometric Theory"},{"key":"S026646661200028X_ref16","doi-asserted-by":"crossref","first-page":"996","DOI":"10.1093\/biomet\/93.4.996","article-title":"Identification of a competing risks model with unknown transformations of latent failure times","volume":"93","author":"Lee","year":"2006","journal-title":"Biometrika"},{"key":"S026646661200028X_ref3","doi-asserted-by":"crossref","first-page":"497","DOI":"10.1111\/1467-937X.00055","article-title":"Semiparametric estimation of the intercept of a sample selection model","volume":"65","author":"Andrews","year":"1998","journal-title":"Review of Economic Studies"},{"key":"S026646661200028X_ref13","doi-asserted-by":"crossref","first-page":"325","DOI":"10.1093\/biomet\/76.2.325","article-title":"The identifiability of competing risks models","volume":"76","author":"Heckman","year":"1989","journal-title":"Biometrika"},{"key":"S026646661200028X_ref17","doi-asserted-by":"crossref","unstructured":"Lee, S. & Lewbel, A.
