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...

This paper uses the exponential generalised heteroscedasticity model-in-mean (EGARCH- M) to analyse the relationship between the equity risk premium and macroeconomic volatility. This premium depends upon conditional volatility, which is significantly affected by the long bond yield, acting as a...

This paper develops an arbitrage-free macroeconomic model of the yield curve and uses this to explain the behaviour of the UK Treasury bond market. Unlike previous models of this type, which assume a homoscedastic error process I develop a general affine model which allows volatility to be...

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...

We adapt the Meiselman (1962) OLS forward rate revision framework to obtain the discrete time analogue of the Heath, Jarrow and Morton (1992) specification and use it for estimating and testing term structure models. Our framework is based upon the Wold representation of the factor dynamics and...

This paper develops a macro-finance model of the yield curve and uses this to explain the behavior of the US Treasury market. Unlike previous macro-finance models which assume a homoscedastic error process and suppose that the one-period return is directly observable, I develop a general affine...

This paper develops a multi-country macro-finance model to study international economic and financial linkages. This approach models economic and financial variables jointly using both to throw light on such issues. The world economy is modelled using data for the US and aggregate OECD economies...
