OxTalks is Changing
OxTalks will soon move to the new Halo platform and will become 'Oxford Events.' There will be a need for an OxTalks freeze. This was previously planned for Friday 14th November – a new date will be shared as soon as it is available (full details will be available on the Staff Gateway).
In the meantime, the OxTalks site will remain active and events will continue to be published.
If staff have any questions about the Oxford Events launch, please contact halo@digital.ox.ac.uk
Networks and Ideology
Abstract:
I study information transmission in networks with ideological agents, having in mind political economy applications such as networks of elected policy-makers in different jurisdictions. When all players are ideologically distant from each other, the optimal network is the line in which players are ordered according to their ideologies. This ordered line network is implemented as Nash equilibrium of a game in which each link requires sponsorship by both linked agents. This is in sharp contrast with earlier results that identified the star as the optimal network for information transmission in the absence of ideology. When agents are clustered in ideologically cohesive groups, it is optimal for all agents that the clusters organize as factions: stars whose only link with the other clusters is through the star centers (the faction leaders). My results suggest positive and normative rationales for horizontal links between like-minded agents in political networks, as opposed to hierarchical networks such as the star that prevail in organizations whose agents’ preferences are closely aligned.
