This new book investigates how the relationships of international business networks (one buyer-multiple suppliers) develop over time, looking at the geographical angle as well as an actor composition point of view. Bart Kamp presents a framework that reveals what business-to-business (b2b) factors explain buyer-supplier co-location patterns, making it possible to predict the geographical behaviour of suppliers, and also assesses whether longevity is truly the deep-rooted feature of international b2b network relationships that it is often claimed to be.
