Our … simulation results on model risk show that the locally risk-minimizing hedges are robust with respect to uncertainty and even …

The effect of monetary policy on financial risk premia is analysed in a simple general equilibrium model with sticky … wages and an optimising central bank. Analytical results show that equity risk premia and term premia are higher under … inflation targeting than under output targeting, and that inflation risk premia are higher for policies that strike a balance …
