In this paper we (1) estimate the effects of international R&D spillovers on total factor productivity growth of the seven largest industrialized countries (G-7); (2) analyze the effect of spillovers on the structure of production , i.e. the effects on factor dema d such as labor and investment...

We model research as a signal on an unknown parameter of a technology.

In this paper we review a number of analytical mothods and issues related to identifying and estimating the source of productivy growth.
