Contagion in networks
The financial crisis of 2007–2008 produced an enormous impact on financial, social and political levels for many world countries (see e.g. [1, 2]).After this crisis the importance of contagion in financial networks gained a practical importance and generated serious academic research with various models proposed for the description of this …Dec 28, 2015 · tion is how network structure interacts with other potential sources of contagion. In the run-up to the crisis, leverage levels increased and capital buffers at some banks were extremely thin. Large financial institutions had increased their reliance on short-term Contagion in Financial Networks † Paul Glasserman and H. Peyton Young* The presence of complex contagion mechanisms has been assessed in various contexts 27, but largely in online social networks and forums 28,29, thanks to their unique data traceability.

Using these algorithms, we study the spread of contagion in scale-free networks with 1,000 players using millions of Monte Carlo simulations. Our analysis provides quantitative and qualitative insight into the design of policies to control or spread contagion in networks. The scope of application is enlarged given the many other situations ...We explore how the probability and potential impact of contagion is influenced by aggregate and idiosyncratic shocks, changes in network structure and asset market liquidity. Our findings suggest that financial systems exhibit a robust-yet-fragile tendency: while the probability of contagion may be low, the effects can be extremely widespread ...FIGURE 1.Illustration of a contagion process. The adoption of norms, behaviors, ideas, technological items, etc. is typically modeled as a spreading process over a network of social contacts. Red and blue nodes of the social network denote, respectively, the adopters (or infected individuals) and the non-adopters (or susceptible) of the item that is …This paper aims to construct a feasible two-layer network model for the emotional contagion of passenger groups in the case of large-scale flight delays. This improved emotional contagion model can study the emotional contagion mechanism and process of delayed passengers between online and offline social contact networks.Risk contagion to China’s banking network from 2013 to 2016. 4.4.1. Contagion caused by credit shocks. In this Section, we examine the trend in the contagion effect due to a credit shock over the 2013–2016 period. Under the complete network structure, the net core tier 1 capital was used to counter the shock.

To avoid these limits, this paper analyzes contagion risk in endogenous financial networks, which includes interbank networks, inter-firm networks and bank-firm networks. Closest to our work is Delli Gatti et al. [12]. However, our paper is different from theirs in network formation. The network formation in this paper is endogenous, while that ...Explosive contagion in SIS epidemics. The evolution of the spreading process depends both on transmission rates and dynamical rules imposed. For concreteness, we start the analysis by employing the exponential synergistic transmission rates (2) for contagion dynamics given by the rules of the SIS epidemic model applied to …
We develop a model for contagion risks and optimal security investment in a directed network of interconnected agents with heterogeneous degrees, loss functions, and security profiles. Our model generalizes several contagion models in the literature, particularly the independent cascade model and the linear threshold model. We state …Contagion effects, also known as peer effects or social influence process, have become more and more central to social science, especially with the availability of longitudinal social network data. However, contagion effects are usually difficult to identify, as they are often entangled with other factors, such as homophily in the selection ...

This paper provides an introduction to the literature on financial contagion in networks. In the first part, we consider contagion via transmission of shocks, i.e. an abrupt drop in the flow of revenue to one firm, which affects other firms connected to it through financial linkages. We then study informational contagion, by which we mean the process whereby a … publix super market at east lake atlanta photospeninsula ave new smyrna beach fllight switch plates lowes Explosive contagion in SIS epidemics.

For concreteness, we start the analysis by employing the exponential synergistic transmission rates (2) for contagion dynamics given by the rules of the SIS epidemic model applied to a population of N individuals.Conclusion. This work expands the literature on financial contagion in interbank credit markets, addressing the research question of how the presence of a network community structure affects the diffusion of liquidity contagion in a banking system. A community structure is a structural feature of complex networks, in which subsets of nodes are ...
