Nous cherchons a apporter une solution satisfaisante a l'enigme de la prime de risque decouverte en 1985 par Mehra et prescott.

Our study is three-fold: we, first review the non-linear tests that we suggest to use to detect non-linearities. We, next, investigate the empirical power of the tests, using simulations under the null hypothesis that we have a linear AR model. We, then, turn to empirical data: the returns of...
