Using synthetic variables in instrumental variable estimation of spatial series models

Auteur(s) et Affiliation(s)



Description :
This paper explores the use of synthetic variables in IV estimation when the analysis is of spatial data series. It considers two situations of interest: first, the case where there are no clear candidates for instrumentation and the instruments are comprised of purely synthetic variables; second, the case when there are substantive but weak instruments that can be enhanced by the addition of synthetic variables. The approach proposed is illustrated with an empirical example.
