Weak Instrumental Variables Models for Longitudinal Data
Longitudinal Data Nearly Weak Instruments Panel Data Weak Instruments Within-group TSLS Estimator
2011/4/1
This paper considers the estimation and testing of a within-group two-stage least squares (TSLS) estimator for instruments with varying degrees of weakness in a longitudinal (panel) Data model. We sho...
Weak Instrumental Variables Models for Longitudinal Data
Weak Instrumental Variables asymp-totic consistency limiting distribution
2011/4/2
In this paper, we study a weak instrumental variables model for longitudinal data. A two stage least-squares estimator (the instrumental variables estimator) is presented. We show that the asymp-totic...
Convergency and Divergency of Functional Coefficient Weak Instrumental Variables Models
Discontinuity Divergence Endogenous variables Functional coefficient model Weak instrumental variables Local linear fitting Simultaneous equations
2011/4/6
In this paper, we consider a simultaneous equations model under a functional coefficient representation for the structural equation of interest and adopt the local-to-zero assumptions as in Staiger an...
Effient Estimation of Partially Varying Coefficient Instrumental Variables Models
Endogenous variables Functional-coefficient models Instrumental variables Local linear fitting Nonparametric smoothing Simultaneous equations
2011/4/6
We study a new class of semiparametric instrumental variables models with the structural function represented by a partially varying coefficient functional form. Under this representation, the models ...
