Using non-parametric weak separability tests that are extended to allow for measurement errors in the data, a broad group of UK monetary assets is found to be weakly separable from consumer goods and leisure over the larger part of the nineties. Financial innovations have made assets with...

Linear models reach their limitations in applications with nonlinearities in the data. In this paper new empirical evidence is provided on the relative Euro inflation forecasting performance of linear and non-linear models. The well established and widely used univariate ARIMA and multivariate...

Numerous studies find that monetary models of exchange rates cannot beat a random walk model. Such a finding, however, is not surprising given that such models are built upon money demand functions and traditional money demand functions appear to have broken down in many developed countries. In...

We compare the empirical performance of a capital certain monetary services index and an index that is extended to contain assets with substantial interest rate risk, such as unit trusts, within a cointegration money demand framework for the UK. Technological changes and innovations have...

This study compares the empirical performance of a capital certain Divisia index and an index that is extended to contain assets with substantial interest rate risk, such as unit trusts, within a cointegration money demand framework. Financial innovations have increased the liquidity of risky...

This paper tests the weak separability of the assets in the Bank of England's household-sector Divisia index from 1977Q1 to 2000Q4. The study is based on a revealed preference framework and uses a nonparametric procedure that jointly tests necessary and sufficient conditions for weak...

This article presents out-of-sample inflation forecasting results based on relative price variability and skewness. It is demonstrated that forecasts on long horizons of 1.5-2 years are significantly improved if the forecast equation is augmented with skewness.

In the Full-Scale Optimization approach the complete empirical financial return probability distribution is considered; and the utility maximizing solution is found through numerical optimization. Using a portfolio choice setting of three UK equity indices we identify several utility functions...

In this paper we propose a unified framework for testing weak separability. We present a new three-step procedure, which is a joint test of necessary and sufficient conditions that takes account of possible measurement error and incomplete adjustment. We illustrate the operational capability of...
