This paper aims to propose a new framework for estimating and forecasting diffusion of high technology products, along with the construction of a price index. Into that context, the “diffusion–price” model is presented, as an innovative concept providing a long term estimation of both price and diffusion elasticity. This corresponds to the bidirectional estimation of the mutual influence of the...

The diffusion of new technologies is often mediated by spatial and socioeconomic factors. This paper empirically examines the diffusion of an important renewable energy technology: residential solar photovoltaic (PV) systems. Using detailed data on PV installations in Connecticut, we identify the spatial patterns of diffusion, which indicate considerable clustering of adoptions. This clustering...

This paper discusses different policy options for the diffusion of information technology (IT) in rural areas. An IT programme for the northern part of Norway is assessed, and the effects of the programme are compared with the consequences of the ongoing diffusion of IT in the region. The analysis shows that the programme initiated some successful projects, but that it as a whole had minor effe...

In this paper, we develop an output diffusion model in which a monopoly firm faces a cost of adjusting output over time and across geographic regions. First, we investigate a dynamic monopoly model and a simple spatial model with only regional adjustment costs. Then, we explore how the firm maximizes profits over time and space, a calculus of variation problem. The Euler equation yields a parti...

Technology or lack of it will play an important role in Africa’s effort to achieve inclusive development. Although a key determinant of competitiveness, new technology can exacerbate exclusion of the majority from the mainstream economic activities. To minimise potential technology exclusion while leveraging its critical role in African’s development, requires insight into technology diffusion ...

Recent Mental Health Acts provide evidence of diverging UK1 and Scottish government policy styles. The UK legislative process lasted almost ten years following attempts by ministers to impose decisions and an unprecedented level of sustained opposition from interest groups. In contrast, the consultation process in Scotland was consensual, producing high levels of stakeholder ‘ownership’. This a...

background and purpose : there has been no report in which preoperative evaluation of adc for prediction of post therapeutic outcome was presented. the aim of our study was to retrospectively evaluation the use of the apparent diffusion coefficient (adc) for the prediction of malignancy and the outcome of malignant astrocytic tumors. methods: we reviewed mri of 26 male and 14 female patients wi...

The aim of this thesis is to contribute to the Open Source Software (OSS) research by a comprehending study of the factors that determine OSS diffusion, as well as the economic and social impact of this diffusion. The research focuses on the process of diffusion over time and assesses cause and effect relationships of the phenomenon. Firstly, it identifies and assesses the factors determining t...
