By formulating a nested test of the asymmetric response model of Bawa, Brown, and Klein (1981), the mean-lower partial moment CAPM (LPMCAPM) of Bawa and Lindenberg (1977) and the mean-variance CAPM of Sharpe (1963, 1964), Lintner (1965) and Mossin (1969), this paper investigates the relative...

In 1990, Britain became the first developed country to reorganise its electricity industry to run on competitive lines. The British reforms are widely regarded as the benchmark for other reforms and the model used provides the basis for reforms of electricity and other network industries around...

Creative destruction is an economic theory of innovation popularised by the Austrian economist Joseph Schumpeter (2006). In this paper, Schumpeter’s theories are used to explain how radical technological innovations in information-intensive industries are influencing the erosion of traditional...
