Local and Consistent Centrality Measures in Parameterized Networks Vianney Dequiedt and Yves Zenou


We propose an axiomatic approach to characterize centrality measures for which the centrality of an agent is recursively related to the centralities of the agents she is connected to. This includes the Katz–Bonacich and the eigenvector centrality. The core of our argument hinges on the power of the consistency axiom, which relates the properties of the measure for a given network to its properties for a reduced problem. In our case, the reduced problem only keeps track of local and parsimonious information. Our axiomatic characterization highlights the conceptual similarities among those measures.

2018 Bergh Funcke Wernberg - Timbro Sharing Economy Index-1fHemsidan.jpg

Andreas Bergh, IFN and Lund University, is one of the authors of this book. The Timbro Sharing Economy Index is the first global index of the sharing economy. The index has been compiled using traffic volume data and scraped data, and provides a unique insight into the driving factors behind the peer-to-peer economy.

About the book

Events

Seminars organized by IFN

 

To present ongoing research informal brown-bag seminars are held on Mondays at 11:30 am. This is an opportunity for IFN researchers to test ideas and results.

Academically oriented seminars are most of the time held on Wednesdays at 10 am. At these events researchers from IFN and other institutions present their research.

In addition, IFN organizes seminars open to the public. Topics for these are derived from the IFN research.
