This paper considers the panel data model with a multifactor structure in both the errors and the regressors which was studied by Pesaran (“Estimation and Inference in Large Heterogeneous Panels with a Multifactor Error Structure, Econometrica, 2006). Estimators are proposed that are...

This paper examines observational equivalence in a class of nonparametric structural equations models under weaker conditions than those currently available in the literature. It allows for several endogenous variables, does not impose differentiability or continuity of the equations which are...

The paper approaches structural econometric models using an algebraic approach. It shows that the invariance properties of the reduced form and the decision to exclude some of the exogenous variables from the structural equations fundamentally affect the functional form of the structural...
