We consider two channels via which foreign inputs into industrial production may lead to productivity effects. The first one concerns dynamic externalities between firms which share technical and organizational knowledge which is vital for the productivity growth of a particular industry. We...

All researchers could gain by sharing information due to the uncertainty of the arrival time of the discovery. As receiving information while withholding...
