Several theories explaining clusters coexist and confront each other. When examined closely, they converge on at least two points. On the one hand, they all find their roots in the late-nineteenth-century work by British economist Alfred Marshall. Going back to Marshall’s seminal contribution is therefore essential, since several ...
