Friendship Network in the Classroom: Parents Bias and Peer Effects
Landini, Fabio; Montinari, Natalia; Pin, Paolo; … - Økonomisk Institut, Københavns Universitet - 2014
We interview both parents and their children enrolled in six primary schools in the district of Treviso (Italy). We study the structural differences between the children network of friends reported by children and the one elicited asking their parents. We find that the parents’ network has a...

Continuous Homophily and Clustering in Random Networks
Gauer, Florian; Landwehr, Jakob - Institut für Mathematische Wirtschaftsforschung, … - 2014
We propose a random network model incorporating heterogeneity of agents and a continuous notion of homophily. Unlike … the vast majority of the corresponding economic literature, we capture homophily in terms of similarity rather than … homophily levels. As a possible application we provide a stylized labor market model, where a firm can hire a worker via the …

Persistent Classmates: How Familiarity with Peers Protects from Disruptive School Transitions
Ly, Son Thierry; Riegert, Arnaud - HAL - 2013
Students' social networks are deeply disrupted during school transitions and students start in a classroom environment where almost all their peers are new. In this study, we investigate the consequences of keeping partly the same classmates during the transition to high school. To overcome the...

Network security
Larson, Nathan - Volkswirtschaftliche Fakultät, … - 2011
In a variety of settings, some payoff-relevant item spreads along a network of connected individuals. In some cases, the item will benefit those who receive it (for example, a music download, a stock tip, news about a new research funding source, etc.) while in other cases the impact may be...

Diffusion and cascading behavior in random networks
Lelarge, Marc - In: Games and Economic Behavior 75 (2012) 2, pp. 752-775
The spread of new ideas, behaviors or technologies has been extensively studied using epidemic models. Here we consider a model of diffusion where the individualsʼ behavior is the result of a strategic choice. We study a simple coordination game with binary choice and give a condition for a new...

Random Graphs as Models of Networks
Newman, M. E. J. - Santa Fe Institute - 2002
The random graph of Erdos and Renyi is one of the oldest and best studied models of a network, and possesses the considerable advantage of being exactly solvable for many of its average properties. However, as a model of real-world networks such as the Internet, social networks or biological...

Ego-Centered Networks and the Ripple Effect
Newman, M. E. J. - Santa Fe Institute - 2001
Recent work has demonstrated that many social networks, and indeed many networks of other types also, have broad distributions of vertex degree. Here we show that this has a substantial impact on the shape of ego-centered networks, i.e., sets of network vertices that are within a given distance...

Diffusion and contagion in networks with heterogeneous agents and homophily
JACKSON, Matthew O.; LOPEZ-PINTADO, Dunia - Center for Operations Research and Econometrics (CORE), … - 2012
among agents in an a social network that exhibits segregation or homophily (the tendency of agents to associate with others … under which a behavior diffuses and becomes persistent in the population. These conditions relate to the level of homophily … with its own type. In particular, we show that homophily can facilitate diffusion from a small initial seed of adopters. …
