Working Papers from HAL

Abstract: This article investigates the evolution of the US risk premium in periods of crisis. First, we estimate a conditional CAPM with time-varying systematic risk and price of risk using a multivariate GARCH-in-Mean model. Second, we study the structural breaks in the US risk premium. Finally, we relate the obtained results to important facts and economic events. Our findings show that the US risk premium increased significantly during periods of crisis and that the last 2007-2009 financial crisis has had the largest impact.
