Digital Databases Internet/Web Mapping Surveying
2015/11/13
The problem of the quality of architectural representation, in a dynamic use finalized in web or database publication, represents the main theme of the current debate regarding the ways in which to sh...
Limit Theory for Panel Data Models with Cross Sectional Dependence and Sequential Exogeneity
Panel Data Models Sequential Exogeneity
2015/9/22
The paper derives a general Central Limit Theorem (CLT) and asymptotic distributions for sample moments related to panel data models with large . The results allow for the data to be cross sec...
MEAN SQUARED ERROR REDUCTION FOR GMM ESTIMATORS OF LINEAR TIME SERIES MODELS
GMM LINEAR TIME SERIES MODELS
2015/9/22
In this paper we analyze Generalized Method of Moments (GMM) estimators for time
series models as advocated by Hansen and Singleton. It is well known that these estimators
achieve efficiency bo...
This paper extends kernel weighted GMM estimators recently proposed by the author in
the context of homoskedastic processes to a class of models with conditionally heteroskedastic
innovations. GMM e...
Optimal Instrumental Variables Estimation for ARMA Models
ARMA conditional heteroskedasticity instrumental variables
2015/9/22
In this paper a new class of Instrumental Variables estimators for linear processes
and in particular ARMA models is developed. Previously, IV estimators based on lagged
observations as instruments ...
