Accounting for Peer Effects in Treatment Response
Dieye, Rokhaya; Djebbari, Habiba; Barrera-Osorio, Felipe - HAL - 2014
When one's treatment status affects the outcomes of others, experimental data are not sufficient to identify a treatment causal impact. In order to account for peer effects in program response, we use a social network model. We estimate and validate the model on experimental data collected for...

A model of influence in a social network
Grabisch, Michel; Rusinowska, Agnieszka - HAL - 2010
In the paper, we study a model of influence in a social network. It is assumed that each player has an inclination to say YES or NO which, due to influence of other players, may be different from the decision of the player. The point of departure here is the concept of the Hoede-Bakker index -...

A study of the dynamic of influence through differential equations
Maruani, Emmanuel; Grabisch, Michel; Rusinowska, Agnieszka - HAL - 2011
The paper concerns a model of influence in which agents make their decisions on a certain issue. It is assumed that each agent is inclined to make a particular decision, but due to a possible influence of the others, his final decision may be different from his initial inclination. Since in...

Ordered Weighted Averaging in Social Networks
Förster, Manuel; Grabisch, Michel; Rusinowska, Agnieszka - HAL - 2012
We study a stochastic model of influence where agents have yes-no inclinations on some issue, and opinions may change due to mutual influence among the agents. Each agent independently aggregates the opinions of the other agents and possibly herself. We study influence processes modelled by...

A model of influence based on aggregation functions
Grabisch, Michel; Rusinowska, Agnieszka - HAL - 2011
The paper concerns a dynamic model of influence in which agents have to make a yes-no decision. Each agent has an initial opinion, which he may change during different phases of interaction, due to mutual influence among agents. The influence mechanism is assumed to be stochastic and to follow a...

Social networks: Prestige, centrality, and influence (Invited paper)
Rusinowska, Agnieszka; Berghammer, Rudolf; Swart, Harrie De - HAL - 2011
We deliver a short overview of di erent centrality measures and influence concepts in social networks, and present the relation-algebraic approach to the concepts of power and influence. First, we briefly discuss four kinds of measures of centrality: the ones based on degree, closeness,...
