To test the existence of tipping points in financial markets, based on the alternating offer strategic model we propose a network of bargaining agents who...

We study the betweenness centrality of fractal and non-fractal scale-free network models as well as real networks. We show that the correlation between degree and betweenness centrality C of nodes is much weaker in fractal network models compared to non-fractal models. We also show that nodes of...
