%T Consistency of Heckman-type two-step Estimators for the Multivariate Sample-Selection Model %A Tauchmann, Harald %J Applied Economics %N 30 %P 3895- %V 42 %D 2009 %= 2011-04-01T04:35:00Z %~ http://www.peerproject.eu/ %> https://nbn-resolving.org/urn:nbn:de:0168-ssoar-241938 %X This analysis shows that multivariate generalizations to the classical Heckman (1976 and 1979) two-step estimator that account for cross-equation correlation and use the inverse Mills ratio as correction-term are consistent only if certain restrictions apply to the true error-covariance structure. An alternative class of generalizations to the classical Heckman two-step approach is derived that condition on the entire selection pattern rather than selection in particular equations and, therefore, use modified correction-terms. It is shown that this class of estimators is consistent. In addition, Monte-Carlo results illustrate that these estimators display a smaller mean square prediction error. %G en %9 journal article %W GESIS - http://www.gesis.org %~ SSOAR - http://www.ssoar.info
