We suggest that the proximity of a country to other countries is a factor that affects its choice as an MNE location. We introduce the concept of a country’s proximity to the global distribution of knowledge, markets and resources, and frame this concept as a function of both geographic distance and the worldwide spatial distribution of these factors. We test our location model on a dataset com...

Abstract Researchers in science and engineering have a long tradition of collaboration, and increasingly carry out these collaborations across geographical distance. Similar trends exist in industry, where virtual teams are increasing in frequency. While we know that such dispersed collaborations are difficult, there is growing evidence of success. The physical and biological sciences have led ...
