This paper characterizes the \nclass of all conditional moment restrictions that lead to \n\u221a<jats:italic>n<\/jats:italic>-consistent estimators for these models. The \nsemiparametric efficiency bound for each conditional moment \nrestriction is derived. In the case of a nonzero bound it is \nshown how an estimator can be constructed and that an appropriately \nweighted version can attain the efficiency bound. These estimators \nalso work when the disturbance is independent of the regressors. \nThe paper discusses combining conditional moment restrictions \nfor more efficient estimation in this case.<\/jats:p>","DOI":"10.1017\/s0266466601175018","type":"journal-article","created":{"date-parts":[[2002,7,27]],"date-time":"2002-07-27T09:16:52Z","timestamp":1027761412000},"page":"863-888","source":"Crossref","is-referenced-by-count":21,"title":["CONDITIONAL MOMENT RESTRICTIONS IN CENSORED AND TRUNCATED \nREGRESSION MODELS"],"prefix":"10.1017","volume":"17","author":[{"given":"Whitney K.","family":"Newey","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"56","published-online":{"date-parts":[[2001,9,25]]},"container-title":["Econometric Theory"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.cambridge.org\/core\/services\/aop-cambridge-core\/content\/view\/S0266466601175018","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2019,5,7]],"date-time":"2019-05-07T18:49:10Z","timestamp":1557254950000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.cambridge.org\/core\/product\/identifier\/S0266466601175018\/type\/journal_article"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2001,9,25]]},"references-count":0,"journal-issue":{"issue":"5","published-print":{"date-parts":[[2001,10]]}},"alternative-id":["S0266466601175018"],"URL":"https:\/\/doi.org\/10.1017\/s0266466601175018","relation":{},"ISSN":["0266-4666","1469-4360"],"issn-type":[{"value":"0266-4666","type":"print"},{"value":"1469-4360","type":"electronic"}],"subject":[],"published":{"date-parts":[[2001,9,25]]}}}
