The paper develops a stand-alone and testable gravity model to explain international patterns of foreign direct investment (FDI). The core model is based on knowledge-based gravitational forces that are directly or indirectly linked to a country's economic mass (GDP). The micro-economic part of...

We analyze the spatial interaction among regions in North America and in Western Europe. We use a gravity model extended by a spatial correlation structures where data allows to evaluate the level of impact and the length of the spatial tail. This allows us to address to effects external to the...
