Technological diffusion, welfare and growth technological succession in the presence of network externalities by Paul Windrum ( )
2 editions published in 2002 in English and held by 5 WorldCat member libraries worldwide
The paper examines the conditions under which technological successions can occur in the presence of network externalities. A multi-agent model is developed in which the product designs offered by firms co-evolve with consumer preferences. Firms compete though product innovation. The model incorporates a modified genetic algorithm (GA) in which imitation is conducted via a process of selective transfer (a one-way crossover) and internal R&D is conducted via selective mutation. Following an initial period in which old technology firms develop their designs and network externalities accrue, a technological shock occurs in which new technology-based firms enter the market. The findings of the model indicate that a necessary condition for a technological succession are the existence of at least one consumer group that champions the new technology, developing new preferences for its characteristics. Further, the introduction of novel characteristics are have a greater bearing on the probability of a succession than incremental gains in characteristics offered by the old technology. Third, the analysis identifies an inverse relationship between time the probability of a technological succession
Structural change in the presence of network externalities: a co-evolutionary model of technological successions by Paul Windrum ( )
2 editions published in 2004 in English and held by 5 WorldCat member libraries worldwide
The paper examines the conditions under which technological successions can occur in the presence of network externalities. A two-stage, multi-agent simulation model is presented in which product designs co-evolve with consumer preferences. It provides a rich framework in which to study the complex phenomenon of quality. Following an initial period, in which old technology firms develop their designs and externalities accrue, a technological shock occurs. New technology firms and new consumer classes enter the market. Data from the simulation model is analysed by identifying a robust econometric model of the probability of succession, given the immediate state of the post-shock market. 4 factors affecting the probability of a succession are identified
Predicting UK business cycle regimes by Chris Birchenhall ( Book )
2 editions published between 1996 and 1997 in English and held by 2 WorldCat member libraries worldwide
"This paper uses logistic regression to construct a one-quarter ahead prediction model for classical business cycle regimes in the UK. The binary dependent variable is obtained by applying simple mechanical rules to date turning points in quarterly real GPD data from 1963 to 1999. Using a range of real and financial leading indicators, several parsimonious one-ahead models are developed for the GPD regimes, with model selection based on the SIC criterion. A real M4 variable is consistently found to have predictive content. One model that performs well combines this with nominal UK and German short-term interest rates. The role of the latter emphasises the open nature of the UK economy."--Editor
