Social Network Analysis of Corruption Structures: Adjacency Matrices Supporting the Visualization and Quantification of Layeredness

Often, corruption is described as taking place within or supported by a network: A collection of individuals structured in such a way as to enable the transaction of bribes for favors. Surprisingly, despite the network nomenclature, corruption is rarely analyzed from the network perspective using the tools of network science. Here, we will argue that analyzing corruption from the perspective of network science is beneficial to its understanding. In passing this chapter, a contribution to the Liber Amicorum in honor of Leo Huberts, then gives a very short introduction into social network analysis.
