I am a Professor Emeritus at the Department of Sociology, University of Haifa.   My main interests are economic sociology, digital economy, social network analysis, and Internet studies.  I examine how social structure shapes economic behavior, and how relational patterns affect exchange and social interaction.  In various studies I have investigated inter-relations among a variety of actors such as: economic producers, nations, organizations,  communities, and Internet users.  My recent research is on the new digital economy, including  online currencies,  algorithmic regulation, and peer to peer monetary groups.
