The economics of web search and social networks has taken a central role in today's Internet activity. 
This workshop aims to bring together researchers and practitioners from academia and industry to discuss the latest developments in these areas.

We solicit work that develops and furthers the economic theory of web search and social networks, with an emphasis on practically oriented work that uses novel models, algorithms, and data to support and guide the research. Position statements and theoretical work with a practical focus are also welcome. 

Examples of topics of interest include:
- web search advertising
- advertisement exchanges
- data exchanges
- game theoretic analysis of web search and data mining
- mechanism design on social networks
- marketing and advertising over social networks
- social network analysis
- network creation games
- models of user behavior
- user incentives and rewards
- geo-based marketing models
- advertising on mobile devices
- economics of privacy
- empirical methods

This workshop can be considered non-archival, meaning contributors are free to publish their results later in journals or conferences. Recently published papers of high quality are also welcome.

We also welcome panel discussion proposals and invited speaker suggestions.

To be held in conjunction with the Sixth ACM WSDM Conference on Feb 4, 2013 in Rome, Italy.
