The Predominant Role of Signal Precision in Experimental Beauty Contests [PDF]

The B.E. Journal of Theoretical Economics, 2016
AbstractThe weight assigned to public information in Keynesian beauty contests depends on both the precision of signals and the degree of strategic complementarities. This experimental study shows that the response of subjects to changes in signal precision and the degree of strategic complementarities is qualitatively consistent with theoretical ...
