Power Indices in the Context of Social Learning Behaviour in Social Networks
Figure 13
Impact of social learning efficiency and social relationship structure. Voters play a voting game in a social network with 13 players and a 30% random connection probability. Subgraph (a) shows the simulation results of voters’ social power and relationship closeness with neighbors. Subgraph (b) shows the simulation results of changes in power indices (), in which voters play a repeated voting game with the social learning efficiency () increasing from to while leaving other parameters unchanged. The integrated power of voters with higher social impact or closeness decreases accompanied by the increases of social learning efficiency (), and the voters with lower social impact or closeness are the opposite, while both cases are possible for the voters with middle social impact or closeness.
