Parameter Uncertainty


This project is concerned with estimation errors and parameter uncertainty in the investment process. The first study extends a previous study using investors reaction to parameter uncertainty to predict the equity premium to further predict a large variety of factor premia. The second study is extending the uncertainty of estimating expected returns to uncertainty about the estimation of the entire return distribution.
