Aggregate models of innovation diffusion do not capitalise on valuable consumer adoption dynamics that emerge from consumer surveys. This is despite other modelling strategies which suggest that such dynamics may be very important to the process of diffusion. We present a segmental Gompertz...
This paper presents research exploring further the concept that many SMEs do not adopt computer based technologies due to decision maker's negative attitudes towards computers generally. Importantly, by assessing the entrepreneur's belief structure, we provide quantitative evidence how SMEs,...

The significant growth of the Information & Communication Technology (ICT) sector has created a widening gap in productivity between the leading industrialised and developing economies. The emergence of a digital divide constitutes a critical constraint on the potential for the future growth of...
This paper deals with statistical modelling to predict failure of Brazilian companies in the light of the Basel II definition of default using a new set of explanatory variables.A rearrangement in the official format of the Balance Sheet is put forward. From this rearrangement a framework of...

Demand forecasting is a crucial aspect of the planning process in supply-chain companies. The most common approach to forecasting demand in these companies involves the use of a simple univariate statistical method to produce a forecast and the subsequent judgmental adjustment of this by the...
A study of short-term forecasting in UK supply chain companies has revealed that some companies make limited use of the facilities that are available in the statistical forecasting software that they have purchased. Despite their costs, the software packages are often used for little more than...
There has been strong empirical evidence that demand variability increases as one moves up the supply chain (from the retailer to the raw materials supplier), a phenomenon called bullwhip effect. This paper examines the bullwhip effect and in particular one of its main causes, demand...
Forecasting at the Stock Keeping Unit (SKU) disaggregate level in order to support operations management has proved a very difficult task. The levels of accuracy achieved have major consequences for companies at all levels in the supply chain; errors at each stage are amplified resulting in poor...
