Spatial Interaction and Economic Growth

Spatial interaction is a central characteristic of economic activity. This thesis aims at providing new insights into the role of integration in the agglomeration-growth nexus and argues that integration is a multidimensional concept that pins down the impact of institutions to a spatial dimension. Also, the impact of genetic distance and data revisions on knowledge spillovers is discussed. Finally, knowledge spillovers are analyzed by applying a multi-region endogenous growth model to the US.
