This study offers a framework for understanding the causes and impact of reengineering. The framework views the causes and impact from two aspects, namely, external and internal dimensions. Using case research, it was found that both external and internal factors were important in driving...

A model of profits switches between four regimes with fixed probabilities; the rationally expected profits stream implies the stock market value. This efficient market model is not rejected by UK post-war time-series behaviour of either profits or the FTSE index.

This article extends the results of Byers et al. (1997) on long memory in support for the Conservative and Labour Parties in the UK using longer samples and additional poll series. It finds continuing support for the ARFIMA(0, d, 0) model, though with somewhat smaller values of the long memory...

Standard parametric specifications of Cumulative Prospect theory (CPT) can explain why agents bet on longshots at actuarially unfair odds. However, the standard specification of CPT cannot explain why people might bet on more favoured outcomes, where by construction the greatest volume of money...

A number of authors have found significant cointegrating relationships between spot exchange rates and domestic and foreign price levels for the major currencies where the magnitude of the coefficients makes economic interpretation of PPP cumbersome. Using theoretically well motivated nonlinear...

This paper analyses the asymmetries in the response of petrol prices to oil price shocks. We show that previous work, based on the determination of asymmetric responses, can be improved upon by allowing for asymmetries in short term dynamics. The paper shows that a significant determinant of the...

The answer to this question, based on a study of 1000 greyhound races, is 'no'. Although the efficient markets hypothesis asserts that speculative market prices optimally encapsulate all relevant information, it is found that 'Shin probabilities' (based on Shin, 1993), in which a dog's winning...
