The Asymptotic Distribution of the LIML Estimator in a Partially Identified Structural Equation
نویسنده
چکیده
We derive a closed form expression for the asymptotic distribution of the LIML estimator for the coefficients of both endogenous and exogenous variables in a partially identified linear structural equation. We extend previous results of Phillips (1989) and Choi and Phillips (1992) where the focus was on IV estimators. We show that partial failure of identification affects the LIML in that its moments do not exist even asymptotically. JEL Classification: C13, C30

Origins of the limited information maximum likelihood and two-stage least squares estimators
Theil, Basmann, and Sargan are often credited with the development of the two-stage least squares (TSLS) estimator of the coefficients of one structural equation in a simultaneous equations model. However, Anderson and Rubin had earlier derived the asymptotic distribution of the limited information maximum likelihood (LIML) estimator by finding the asymptotic distribution of what is essentially...
متن کاملOn the Asymptotic Optimality of the LIML Estimator with Possibly Many Instruments
We consider the estimation of the coefficients of a linear structural equation in a simultaneous equation system when there are many instrumental variables. We derive some asymptotic properties of the limited information maximum likelihood (LIML) estimator when the number of instruments is large; some of these results are new as well as old, and we relate them to results in some recent studies....
متن کاملAn Optimal Modification of the LIML Estimation for Many Instruments and Persistent Heteroscedasticity
We consider the estimation of coefficients of a structural equation with many instrumental variables in a simultaneous equation system. It is mathematically equivalent to an estimating equation estimation or a reduced rank regression in the statistical linear models when the number of restrictions or the dimension increases with the sample size. As a semi-parametric method, we propose a class o...
متن کاملA New Light from Old Wisdoms : Alternative Estimation Methods of Simultaneous Equations with Possibly Many Instruments
We compare four different estimation methods for a coefficient of a linear structural equation with instrumental variables. As the classical methods we consider the limited information maximum likelihood (LIML) estimator and the two-stage least squares (TSLS) estimator, and as the semi-parametric estimation methods we consider the maximum empirical likelihood (MEL) estimator and the generalized...
متن کاملThe Asymptotic Distribution of Tests for Over-identification in Partially Identified Linear Structural Equations
We study the asymptotic distribution of the statistics suggested by Sargan/Byron/Wegge and Basmann for testing for over-identification in partially identified linear structural equations and derive closed form expressions for their asymptotic densities. These allow us to understand the asymptotic behaviour of these statistics in cases where identification of the structural parameters fails. We ...
