C) UNPUBLISHED RESEARCH
Digit Ratios and Social Preferences: A Comment on Buser (2012) (with Pablo Brañas), Chapman University Working Paper 13-31 (2013).
This comment illustrates that the measurement method of digit ratios used in Buser (2012) is biased and discusses the potential econometric issues arising in the econometric analysis due to this bias. The comment was rejected in Games and Economic Behavior and we are no longer trying to publish it. To give the problems in Buser (2012) certain visibility, the working paper is available on our webpages. We hope this will prevent other scholars from using Buser's methodology in their future work. We would like to thank the referees and other people working in related topics (see the Acknowledgment footnote) for their support.
A Survey on Social Preferences, Ikerlanak Working Paper Series 36/09 (2009).
This paper surveys the theories of social preferences and shows formally their predictions in classic experimental protocols. I have never tried to publish it. However, it is very useful while teaching the social preferences in undergraduate as well as graduate classes of experimental and behavioral economics.
