Recent empirical studies have highlighted that valuation effects associated with fluctuations of nominal exchange rates are one of the key components that drive the behaviour of the net foreign assets position of a country. In this paper, we propose a two-country overlapping-generations model of...

The purpose of this paper is to examine the covariance structure of multivariate GARCH (M-GARCH) models that have been introduced in the literature the last fifteen years, and have been greatly favoured by time series analysts and econometricians. In particular, we analyze the second moments of...

This paper investigates an equilibrium model of the term structure of nominal interest rates on default-free, zero coupon bonds. In a pure exchange economy with incomplete information, a representative agent is unable to observe the expected growth rates of both exogenous real output and money...

There is a large theoretical literature in both economics and psychology on decision making under ambiguity (as distinct from risk) and many preference functionals proposed in this literature for describing behaviour in such contexts. However, the empirical literature is scarce and largely...

Since the beginning of 2000s the world economy has witnessed a sub-stantial increase in oil prices, which is seen to be an important source of economic fluctuations, causing high inflation, unemployment and low or negative growth rates. Recent experience, however, has not validated this view....
