Bayesian learning in social networks

[PDF] from 128.32.135.2
Full text - MIT Libraries
D Gale… - Games and Economic Behavior, 2003 - Elsevier
We extend the standard model of social learning in two ways. First, we introduce a social
network and assume that agents can only observe the actions of agents to whom they are
connected by this network. Secondly, we allow agents to choose a different action at each ...

Individual preferences for giving

[PDF] from escholarship.org
R Fisman, S Kariv… - Yale Law & Economics …, 2005 - papers.ssrn.com
Abstract: Economic thought has in recent years increasingly departed from the paradigm of
narrow self-interestedness to take up other-regarding preferences. We study one class of
such preferences-individual preferences for giving.
