The dynamics of betas will also vary across assets according to the assets' cash-flow structure. In a calibration exercise, we show that value and growth firms have cash-flow structures that imply an opposing beta dynamics that goes in the direction of solving the value premium puzzle. During high uncertainty periods, value betas are higher while growth be...
