Nestedness in Networks: A Theoretical Model and Some Applications Michael D. König, Claudio J. Tessone and Yves Zenou


We develop a dynamic network formation model that can explain the observed nestedness in real-world networks. Links are formed on the basis of agents' centrality and have an exponentially distributed lifetime. We use stochastic stability to identify the networks to which the network formation process converges and find that they are nested split graphs. We completely determine the topological properties of the stochastically stable networks and show that they match features exhibited by real-world networks. Using four different network data sets, we empirically test our model and show that it fits well the observed networks.

Interdisciplinary European Studies

Trust in the European Union in Challenging Times

2018-Trust-in-the-European-Union-by-Oxelheim.jpg

This is the first book in the Interdisciplinary European Studies collection. This volume provides an interdisciplinary perspective on trust in the EU from the vantage point of political science, law and economics. Lars Oxelheim, Lund University and affiliated to IFN, is one of the authors.

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.
