Equity Premium Used in 2011 for the USA by Analysts, Companies and Professors: A Survey

The average Market Risk Premium (MRP) used in 2011 by professors for the USA (5.7%) is higher than the one used by analysts (5.0%) and companies (5.6%). The standard deviation of the MRP used in 2011 by analysts (1.1%) is lower than the ones of companies (2.0%) and professors (1.6%). Most previous surveys have been interested in the Expected MRP, but this survey asks about the Required MRP. The paper also contains the references used to justify the MRP, comments from 58 persons that do not use MRP, and comments of 110 that do use MRP. The comments illustrate the various interpretations of the required MRP and its usefulness. Professors, analysts and companies that cite Ibbotson as their reference use MRP for USA between 2% and 14.5%, and the ones that cite Damodaran as their reference use MRP between 2% and 10.8%.
