R&D components are investigated in dynamic factor demand models using pooled Japanese data. Models without R&D, with R&D (double or) wrongly counted and (once or) correctly counted are compared by means of GMM estimates, (non-)nested GMM tests and residual analyses. The results indicate that R&D...
