Confidence intervals for bias and size distortion in IV and local projections - IV models

Ganics, Gergely Akos; Inoue, Atsushi; Rossi, Barbara - 2018

En este documento se proponen nuevos métodos con el objetivo de construir intervalos de confianza para el sesgo del estimador de mínimos cuadrados en dos etapas y para la distorsión del tamaño del test de Wald asociado a los modelos de variables instrumentales. Es importante destacar que...

Consistent Estimation with Weak Instruments in Panel Data

Kao, Chihwa; Liu, Long - Center for Policy Research, Maxwell School - 2007

This note analyzes the asymptotic distribution for instrumental variables regression for panel data when the available instruments are weak. We show that consistency can be established in panel data.

A Remark on Bimodality and Weak Instrumentation in Structural Equation Estimation

Phillips, Peter C. B. - Cowles Foundation for Research in Economics, Yale University - 2005

/LIML estimator is always bimodal and this is most apparent when the concentration parameter is small. Weak instrumentation is the … of the concentration parameter and the weakness of the instruments. The limit distribution of the OLS estimator is normal …
