We discuss the effects of resonances in driven quantum systems within the context of quantum averaging techniques in the Floquet representation. We consider in particular iterative methods of KAM type and the extensions needed to take into account resonances. The approach consists in separating...

Trading volume and order flow have both been closely associated with informed trader activity in the market microstructure literature. Using theory that explains regular intraday patterns in trading data, we transform these two variables into proxies for private information and examine their...

From Prof Steve Thomas and Mr Richard A. Werner.Sir, Mervyn King deserves praise for recognising that things could turn ugly when the housing bubble bursts ("King links rises in rates to fears on house prices", July 1). But is his recommended plan of action suitable - namely to raise interest...

This paper presents and implements a number of tests for non-linear dependence and a test for chaos using transactions prices on three LIFFE futures contracts: the Short Sterling interest rate contract, the Long Gilt government bond contract, and the FTSE 100 stock index futures contract. While...

This paper examines several problems involved in modelling the structure of consumer behaviour. A new model of consumer demand is presented which encompasses the indirect translog, the CES and the LES as special cases, enabling nested comparisons to be made. Within this framework we show that...

Relatively there is little empirical research that has been taken to understand how the underlying economy affects customers’ subsequent financial product purchase behaviours. A better understanding of this influence and being able to predict the probability of purchasing are important for...

Purpose – The purpose of this research is to undertake an examination of the impacts of socio-demographic and economic variables on the probability of purchasing financial products. There is relatively little empirical research that has been taken to understand how the underlying economy...

This article examines how microstructure effects, evident in high frequency data, influence bid–ask spreads and volatility in transaction price series. It uses the event of European Monetary Union (EMU), and the upheaval that this entailed, as an opportunity to empirically investigate these...

The extent of non-trading is shown to be much greater in the UK than in the more heavily researched US equity markets. Over the period 1975 to 1995 we find that almost 44% of all stocks in our sample failed to trade on the last day of a given month, a figure which is significantly higher than...
