Many mechanisms have been developed to deliver only relevant informationto the web users and prevent information overload. The most popularrecent developments in the e-cornmerce domain are the user-preference basedpersonalization and recommendation techniques. However, the existing...

This paper provides a framework of using news articles andeconomic data to model the exchange rate changes between Euro andUS dollars. Many studies have conducted on the approach of regressingexchange rate movement using numerical data such as macroeconomicindicators. However, this approach is...

Fully taking into account the hints possibly hidden in the absent data,this paper proposes a new criterion when selecting attributes for splitting tobuild a decision tree for a given dataset. In our approach, it must pay a certaincost to obtain an attribute value and pay a cost if a prediction...

Whilst Cumulative Prospect theory (CPT) provides an explanation of gambling on longshots at actuarially unfair odds, it cannot explain why people might bet on more favoured outcomes. This paper shows that this is explicable if the degree of loss aversion experienced by the agent is reduced for...

Nonlinear models of deviations from PPP have recently provided an important, theoretically well motivated, contribution to the PPP puzzle. In recent work the equilibrium level has been modelled either as constant or as time varying with very similar statistical fits and very different economic...

Recent research by Gu and Wu (2003) and Basu and Markov (2004) suggests that the well-known optimism bias in analysts’ earnings forecasts is attributable to analysts minimizing symmetric, linear loss functions when the distribution of forecast errors is skewed. An alternative explanation for...

This paper adopts a nonlinear framework to model the deviations of the real exchange rate from its fundamental value implied by International Real Business Cycle models with complete asset markets. By focusing on the post Bretton Woods era, we find that in several cases there is a long run...
