Contagion in networks.
Many behavioral phenomena have been found to spread interpersonally through social networks, in a manner similar to infectious diseases. An important difference between social contagion and traditional infectious diseases, however, is that behavioral phenomena can be acquired by non-social mechanisms as well as through social transmission.
Prediction of contagion dynamics is of relevance for epidemic and social complex networks.

Four different models and corresponding algorithms describe influence or information spreading in social networks. Alg-cc and Sim-sc, indicated by the green colour, are basic models for describing complex contagion and simple contagion processes, respectively. Alg-cc is based on an analytical mathematical expression.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 ...

The network is particularly vulnerable to contagion when the originating node is large, highly leveraged, and, crucially, has a relatively high proportion of its obligations held by other financial institutions as opposed to the nonfinancial sector, what we will call high financial connectivity.
fore generates less total peer adoption in the network. Overall, we find that viral product design features generate econometrically identifiable peer influence and social contagion effects and provide a model for how randomized trials can identify peer influence in networks. 2.

We consider the most general setting in which different communication platforms or categories form multiplex networks. Specifically, we propose a contact-based information spreading model, and show that the critical point of the multiplex system associated with the active phase is ...Learn More .

Introduction. The aim of this chapter is to provide an introduction to the literature on financial contagion in networks. We aim to do this by focusing on a limited number of papers in some formal detail, trying to illustrate their analogies and differences as much as possible within a common framework. We divide the discussion in two parts.
While the tendency of social networks to act as vehicles for social influence within organizations has been long recognized in empirical organizational research (Krackhardt & Porter, 1985), the underlying mechanisms of social contagion linking the individual and social remain poorly understood.
The risk contagion research is carried out from three aspects:guarantee mechanism, partner selection mechanism, and production parameter. The research shows that: (1) Firm size distribution takes on a power-law tail. (2) Guarantee network provides a channel for risk contagion and aggravates risk contagion among firms.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 a population of N individuals.To study the transition from simple to complex contagion in the LFC, we consider networks of N + 1 = 240 agents. This is significantly smaller than for the LTM, but the ...Additive manufacturing plays a decisive role in the field of industrial manufacturing in a wide range of application areas today. However, process monitoring, …There are many studies in the marketing and diffusion literature of the conditions in which social contagion affects adoption processes. Yet most of these studies assume that social interactions do not change over time, even though actors in social networks exhibit different likelihoods of being influenced across the diffusion period. Rooted in physics and epidemiology theories, this study ...Contagion: In economics and finance, a contagion can be explained as a situation where a shock in a particular economy or region spreads out and affects others by way of, say, price movements. Description: The contagion effect explains the possibility of spread of economic crisis or boom across countries or regions. This phenomenon may occur ...

Related literature. Our study is related to separate strands of the literature on interbank networks. First, it relates to the literature on contagion channels.The development of chickenpox can be traced to 17th century Europe. Along with a number of other contagions, it migrated to the Western Hemisphere in what has been called the Columbian Exchange.The risk contagion of the stock market is more from the downside of fundamentals and the low expectations of investors. In the high-frequency connectedness network structure, Saudi Arabia and France have the highest TO connectedness and NET connectedness, indicating that they are the senders of short-term risk contagion due to emergencies.
Multilayer networks represent systems in which there are several topological levels each one representing one kind of interaction or interdependency between the systems' elements. These networks have attracted a lot of attention recently because their study allows considering different dynamical modes concurrently.

The content individuals produce in daily social-media-based micro-communications, and the emotions therein expressed, may impact the emotional states of others. A recent experiment performed on Facebook hypothesized that emotions spread online, even in absence of non-verbal cues typical of in-person ...Here, we propose an alternative method for detecting emotional contagion in massive social networks that is based on instrumental variables regression, a technique pioneered in economics [23]. In an experiment we would directly control each user's emotional expression to see what impact it has on their friends' emotional expression.Back to Our Network. Ho Chi Minh City.

Our work on social networks and human behavior thus covers several domains and relies on diverse data and approaches. It builds on prior research on ‘peer effects’ and interpersonal influence by examining data in which individuals are embedded in networks much larger than two people. We summarize this work and describe critiques, …Network contagion models are relevant policy tools to monitor systemic risk.
