The Longitudinal nature of patent value and technological usefulness exploring PLS structural equation models

The purpose of this paper is to investigate the evolution of patent value and technological usefulness over time using longitudinal structural equation models. The variables are modeled as endogenous unobservable variables which depend on three exogenous constructs: the knowledge stock used by compa...
