The bias to order T~(-2) for the general k-class estimator in a simultaneous equation model

摘要

Kinal (1980) showed that k-dass estimators for which k<1 possess all necessary higher moments. A bias approximation to order T~(-2) is derived for the general k-class estimator extending the earlier result for 2SLS of Mikhail (1972) thus improving our knowledge of a potentially interesting class of estimators.
