Unconstrained estimates of the equity risk premium

Abstract

Estimates of the equity risk premium implied by analyst forecasts-generally 2-4 %-are often significantly below realized equity returns of 6 %. Measurement error could result from conservative assumptions, reliance upon consensus rather than detailed forecasts, the use of market rather than target prices, and regression analysis, which can be influenced by a small number of observations. We address these potential sources of measurement error. Our estimates are consistent with subsequently realized returns and capture systematic risk exposure. Alternative techniques could capture another form of priced risk or identify firm characteristics associated with systematic mispricing. From 1999 to 2008, we estimate an average equity risk premium in the United States of 5.3 %. The estimate increases from 3.1 % for 1999-2000 to 5.9 % from 2001 to 2008, comparable to the historical average of realized equity returns
