We take the Fujita & Thisse (2003) growth-cum-geography model to investigate the implications of seeing social ties as an important reason for the generation of knowledge. Moreover, we model migration as an important channel through which the distance decay effect of cross-regional knowledge...

We argue that geographical clustering helps the weakest firms to survive. We model this neglected negative externality by adapting the heterogeneous firms model of Melitz (2003) to include firms that invest in R&D and firms that do not. Separating the chance of post-entry market exit into a...
