Explaining the Equity Risk Premium

Working Paper: CEPR ID: DP5017

Authors: Laurian Lungu; Patrick Minford

Abstract: We develop a simple overlapping generations model in which the young have a choice in investing in equities and index-linked bonds. Projections of share price uncertainty over a 30-year period show that the risk associated with such a long-term investment predicts an equity premium that matches historical values.
