unpublished papers

• Coordination with Independent Private Values: Why Pedestrians Sometimes Bump into Each Other, February 2014. I wrote this paper without knowing this 2007 paper by Bill Sandholm, which is a mostly more comprehensive analysis than mine. I like the story in my paper, but there is little added value in terms of formal results. However this paper has eventually led to Renegotiation and Coordination with Private Values - with Yuval Heller, September 2019 and supplementary online appendix (see also above), which does have very new results.
• An incomplete information justification of symmetric equilibrium in symmetric games. 
  With Brian Rogers, November 2010.
• The Evolution of Moral Codes of Behavior. With Carlos Rodriguez-Sickert, revised May 2009. 
• Individual and group selection in symmetric 2-player games. November 2003.
