Contagion in networks
According to social contagion theory [29, 30], a person's attitudes and behavior can be contagious to others in their social networks [31]. Thus, people tend to adapt their actions to the behavior ...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.

Xiong et al. (2018) proposed an emotional independent cascade model in which individual emotion can affect the subsequent emotion of his/her friends aiming to show the detailed process and characteristics of emotional contagion within social media (Xiong et al., 2018).

First, we construct a high-dimensional dynamic financial network model to capture risk contagion effects. Second, considering the ripple effect of financial risk …Contagion is defined as a significant increase in cross-market co-movement of asset returns (Dungey et al., Citation 2004; Forbes & Rigobon, Citation 2002). According to Forbes and Rigobon (Citation 2002) and Celik (Citation 2012), the co-movements between financial markets may arise from the contagion or interdependence among financial markets ...In terms of Internet speed, most people agree that faster is always better. If you’re wondering what your network speed is, there are speed tests available on the Internet that enable you to test and measure the speed of your connection.This paper develops an analytical model of contagion in financial networks with arbitrary structure. We explore how the probability and potential impact of contagion is influenced by aggregate and idiosyncratic shocks, changes in network structure and …Here we are interested in studying the differences on the final contagion densities in networks with or without memory (Fig. 5.b main panel), all other parameters of the rumor spreading model ...Systemic Risk and Stability in Financial Networks Daron Acemogluy Asuman Ozdaglarz Alireza Tahbaz-Salehix This version: January 2013 First version: December 2011 Abstract We provide a framework for studying the relationship between the financial network architecture and the likelihood of systemic failures due to contagion of counterparty risk.Antonio Cabrales & Piero Gottardi & Fernando Vega-Redondo, 2017.

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.Complex contagions that require more than two contacts to "infected" sources can be described with threshold rules. In the following description of such general contagion dynamics, the components of a network are regarded as either active or inactive and change their state according to three fundamental processes: (i) an active node becomes spontaneously inactive in a time interval ...Two algorithms for computing the contagion threshold are presented. • Contagion thresholds of connected sets of nodes in a tree are completely determined. • Bounds for contagion thresholds of nodes in a general network are established. • Having more than six friends may make you more contagious than your locally dominating friend. •Keywords: Di usion, Homophily, Segregation, Social Networks.

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.A great network makes all the difference between a successful consulting career and a stagnant one. Learn why networking is crucial and how to do it best. Trusted by business builders worldwide, the HubSpot Blogs are your number-one source ...Abstract. The vast majority of strategies aimed at controlling contagion processes on networks consider a timescale separation between the evolution of the system and the unfolding of the process. However, in the real world, many networks are highly dynamical and evolve, in time, concurrently to the contagion phenomena.
Contagion theory is mixed. Results Naive contagion estimates.
