Economics: An Emerging Small World?
Goyal, Sanjeev; van der Leij, Marco; Moraga, Jose Luis - 2004
This paper examines the small world hypothesis. The first part of the paper presents empirical evidence on the evolution of a particular world: the world of journal publishing economists during the period 1970-2000. We find that in the 1970's the world of economics was a collection of islands....
