GARCH-in-mean modelIn this paper, we review the Lucas hypothesis that the impact on real output to unanticipated nominal shocks is inversely related across countries to the variability of such shocks. In doing so, we model money supply volatility explicitly to capture important volatility effects ...

I propose an estimation strategy for the stochastic time-varying risk premium parameter in the context of a time-varying GARCH-in-mean (TVGARCH-in-mean) model. A Monte Carlo study shows that the proposed algorithm has good finite sample properties. Using monthly excess returns on the CRSP inde...
