The concept of center and periphery was first introduced by [[Raúl Prebisch]] in the 1950s. However, the qualitative notion that social networks can have a core-periphery structure has a long history in disciplines such as sociology, international relations (Nemeth & Smith, 1985), and economics (Snyder & Kick, 1979). Observed trade flows and diplomatic ties among countries fit this structure. Paul Krugman (1991) suggests that when transportation costs are low enough manufacturers concentrate in a single region known as the core and other regions (the periphery) limit themselves to the supply of agricultural goods.
