The price of complexity in financial networks. [PDF]
Proc Natl Acad Sci U S A, 2016 Significance Estimating systemic risk in networks of financial institutions represents, today, a major challenge in both science and financial policy making. This work shows how the increasing complexity of the network of contracts among institutions comes with the price of increasing inaccuracy in the estimation of systemic risk. The

The hyperbolic geometry of financial networks. [PDF]
Sci Rep, 2021 AbstractBased on data from the European banking stress tests of 2014, 2016 and the transparency exercise of 2018 we construct networks of European banks and demonstrate that the latent geometry of these financial networks can be well-represented by geometry of negative curvature, i.e., by hyperbolic geometry.

Transfer Entropy between Communities in Complex Financial Networks [PDF]
Entropy, 2019 In this paper, we analyze information flows between communities of financial markets, represented as complex networks. Each community, typically corresponding to a business sector, represents a significant part of the financial market and the detection ...

Social dynamics of financial networks [PDF]
EPJ Data Science, 2018 Recurrent interactions between agents play an essential role in the organization of a dynamic complex system. While intensive researches have been done on social systems formed by human interactions, dynamical rules are not well understood in economic ...

Proceedings of the Second ACM International Conference on AI in Finance, 2021 We study financial systems from a game-theoretic standpoint. A financial system is represented by a network, where nodes correspond to firms, and directed labeled edges correspond to debt contracts between them. The existence of cycles in the network indicates that a payment of a firm to one of its lenders might result to some incoming payment.

A Network View of Portfolio Optimization Using Fundamental Information
Frontiers in Physics, 2021 This article proposes the use of a novel approach to portfolio optimization, referred to as “Fundamental Networks” (FN). FN is an effective and robust network-based fundamental-incorporated method, and can be served as an alternative to classical mean ...
