Instrumental-Variable Estimation of an Error-Components Model<869:IEOAEM>2.0.CO;2-6
p. 869-880

Takeshi Amemiya, Thomas E. MaCurdy

This paper proposes efficient instrumental-variable estimators for an error-components model considering alternative assumptions about the sources of endogeneity and the variance-covariance properties of disturbances. The analysis develops a general result that provides for the construction of asymptotically efficient estimators when there exist variables that are predetermined for only a subset of the equations making up a structural model.
