This paper explores the implications of time varying volatility for optimal monetary policy and the measurement of welfare costs. We show how macro-economic models with linear and quadratic state dependence in their variance structure can be used for the analysis of optimal policy within the...

In this paper, we used modified multivariate EGARCH-M models to assess the relation between the equity risk premium, macroeconomic risk, and inflationary expectations. To rationalise this link between equity risk premia and macroeconomic volatilities, we built our empirical study on the...
